1.5
Power Supply
A safety-inspected power cable that satisfies the regulations of the
country of use is required for the device. Devices with metal housings
must only be connected to a grounded, shock proof socket.
The device must not be operated unless the nominal voltage of the
device matches the local supply voltage. Check the supply voltage of
the device in stationary devices.
When connecting and disconnecting wires, refer to the instructions in
the operating instructions for the device.
Do not use any damaged wires (damaged insulation, exposed wires). A
faulty wire poses a risk of electric shock or fire hazard.
1.6
Setup and Operation
During installation, make sure that no objects or fluids get inside the
device (risk of electric shock, short circuit).
In emergencies (e. g. if there is damage to the housing, control
elements or the mains cable, if fluids or foreign bodies have infiltrated
the equipment), switch off the power supply to the device immediately
and notify your SYMEO Service.
Protect the contacts of all of the device's sockets and plugs from static
electricity. Do not touch the contacts. If it is ever necessary to touch the
contacts, take the following precautionary measures: Touch a grounded
object or carry a ground strap before touching the contacts. This will
divert static charges.
Proper operation (in accordance with IEC60950/EN60950) of the device
is only assured if the housing and integral covers for mounting slots are
fully installed (electric shock, cooling, fire protection, noise suppression).
If necessary, refer to the corresponding instructions in the operating
instructions for the device.
In the case of high outside temperatures and intense, direct solar
radiation or other radiant heat, it may be necessary to provide a sun or
heat shield.
1.7
System Extensions and Accessories
Data links to peripheral devices must be provided with adequate
shielding.
For LAN cabling, the requirements in accordance with EN 50173 and
EN 50174-1/2 apply. Use of either a Category 5 shielded cable for
10/100 Ethernet or Category 5e shielded cable for gigabit Ethernet is a
minimum requirement. The specifications of standard ISO/IEC 11801

The folder “mobileUnits”
contains all files for the
vehicles. The folder
“staticCells” contains all files
for the LPR-2DB Integral
Station including the master
LPR-2DB Integral Station. The
folder name for all LPR stations

To allocate the stations for the customer, it makes sense to create a
text-file that describes the function of that LPR station, i.e.
“forklift_123_customer.txt”.
If it is later necessary to replace a LPR unit (e.g. due to a defect) you
can find easily the necessary configuration files for the appropriate
station.

3 System Description
SYMEO Industrial Local Positioning Radar (LPR) is a system for contactless, real-time
determination of distances and positions.
LPR B 2D is a distance measurement system which is particularly well suited for use in very
harsh, industrial environments, in which other systems such as mechanical rotary encoders
or lasers cannot function for long periods.
The system composes of mobile units and fixed, wall-mounted units at known positions. The
mobile units compute its position using the delay time of the radio-signals between wall
mounted units and the mobile unit.
LPR-2DB has an in-build communication channel to handle all background communication
necessary for operation of the positioning system. LPR-2DB units use the same frequency
band and the same hardware for communicating as for measuring distance. This means that
no external WLAN or cable networks are needed for transmitting measurement values and
other reference data.
The system is organized in a cellular fashion. 4 to 6 wall-mounted units are arranged to form
a group with a unique group-ID and an individual measurement ID ranging from 0-5 for each
wall-mounted unit. For the communication between the mobile unit and the 6 transponders 6
different measurement channels separated in frequency (FDMA) are used, allowing instant
position computation.
For arrangements with more than 6 transponders neighboring cells with different group IDs
can be set up. To separate the communication of neighboring cells different communication
frequency channels can be assigned for different cells. For some system topologies an
additional cell-master is required to handle measurement timing and communication.

Operating Mode
There are different system topologies to determine a 2D position with a Symeo LPR® system.
Which operating is best suited depends on the application and the environment. It depends
on the number of mobile units you want to track and on the number of cells which are
necessary to cover the environment.
Operating Mode

The operating mode is normally set by Symeo after consulting the
customer.
3.2.1
Operation Mode 1: Basic Cell
4-6 fixed mounted units (i.e. at a wall or on light poles) at known positions as basic cell and
one single mobile unit form the setup for mode 1. The fixed mounted units are configured as
reply units or “slave transponders”. Each fixed mounted unit has the same group ID and a
different measurement ID ranging from 0...5. Additionally, the units within the same group
must be set to the same communication channel. The positions of the fixed mounted units
are known to the mobile unit. The measurement of mode 1 is based on the measurement
principle RTOF (Round Trip Of Flight). It is organized as follows:
The mobile unit acts as “master base-station” and sends a measurement command to the
fixed mounted units. The fixed mounted units synchronize to this signal and transmit a return

signal with precisely known delay and an individual frequency offset corresponding to the
fixed mounted unit measurement ID. The mobile unit computes the round-trip time-of-flight
and therefore the 1D distance to each transponder. Finally, the mobile unit calculates of all
single 1D distances a 2D position.

3.2.2
Operation Mode 2: Managed Cell
Mode 2 is used when several mobile units are present at the same time within the cell. In this
case the measurement intervals between the mobile units are synchronized. This is done by
using the setup of mode 1 and an additional master transponder for coordination. The master
transponder assigns the measurement slots for different mobile units. The mobile unit no
longer initializes the measurement and simply acts as base-station. The measurement of
mode 2 is based on the measurement principle RTOF (Round Trip Of Flight). The detailed
measurement procedure is as follows:
The master transponder repeatedly broadcasts his group-ID. Base-stations in range reply to
this broadcast with their ID. The master transponder keeps a list of active base-stations in
range, assigns measurement slots to the stations and broadcasts them to the individual
stations in range. The base-station then transmits the broadband measurement signal and
computes its position as described in mode 1.
Measurement rate for the stations present can be set to equal distribution for all mobile units
or to a preferred channel with maximum measurement rate for one base-station and slower
measurement rate for the remaining stations.
System Description

Product Documentation
If desired the master transponder can store the coordinates of the cell (mode 2b). The
master transponder then repeatedly broadcasts his coordinates and all base-stations in
range receive the data. Alternatively the coordinates can be kept on the mobile unit
permanently as in mode 1 (mode 2a).
Finally, depending on the master-transponder type, the position data of the mobile units can
also be transmitted to the master transponder and can be retrieved by the user.

5: Broadband measurement signals
3.2.3
Operation Mode 3: TDOA
Sometimes many mobile units are present in a cell, or measurement of the position of mobile
units at exactly the same time is desired. Using mode 3, only the fixed mounted units
transmit broadband measurement signals. The mobile unit receives these signals and
computes its position from the time-differences of the signals.
Mode 3 has the same basic hardware as mode 2, but the organization of the measurement is
completely different:
The master transponder sends a broadband synchronization signal preceded by the group ID
of the cell. The slave transponders precisely synchronize to this signal and in turn each
transponder transmits the broadband measurement signal. All base-stations within the cell
receive the signal and compute the time-difference between the received signals. The timedifference is used to obtain the position.

Additionally to the described solution of a fixed master, there is the
possibility to use a moving master. In this case each fixed mounted unit
can be the master. The sequence is set by the user.

Vehicle Model
To determine a 2D-position with an LPR-2DB system a Kalmar filter is used. Therefore a
system model is necessary which represents the system. Depending on the vehicle type in
your application different models can be used:
Hover-Track-Model
Vehicle-Track-Model
Depending on the chosen model for the Kalman filter different numbers of states are
estimated (position, velocity, acceleration, angle, etc).

Hover-Track
The HoverTrack model is used for vehicles that can move in x- and y-direction but cannot
turn over its center. A typical example is the trolley of a crane. The name based on a
hovercraft which can move forward and backward as well as sideward.
To make a 2D-positioning the mobile unit needs at least one antenna. The usage of a
second, third or fourth antenna results in more robust and more reliable position.

Vehicle-Track
If the object can also turn around its center the vehicle-track model is used. Examples for the
vehicle model are each kind of steerable vehicles (fork lift, van carrier, automobile, etc.). It is
possible to determine besides the 2D position also the orientation of the vehicle. For this it is
at least a second antenna necessary.

BSB000605 (double receiver, TCP/IP interface, 2 antenna ports)
BSB000606 (double receiver, RS232 interface, 2 antenna ports)
During Installation, the LPR-2DB Station has to be opened. Therefore it
is important to avoid ingress of moisture, dust or any particles into the
housing during the installation process. Make sure that there is enough
room for the connectors, and particularly that the antenna cable is
accessible; pay attention to the permitted bending radius (center of
radius to cable core) for standard cables of 10,5cm (for multiple bending
under mechanical load) and 4cm (unloaded and static bending).
The LPR-2DB Station should preferably be installed so that the
connecting sockets point downwards. In this way, the connections are
protected from rain and dust.
To install the LPR-2DB Station, you require 4 round head M6 x 30
screws (at least).
Check the position of the station on the device on which the LPR-2DB Station is to be
installed (e.g. a crane bridge). Bear in mind the installation instructions listed above.
Drill holes in the device on which the LPR-2DB Station/ Rubber pads are to be installed.
Drill-hole distances: 11 cm wide, 24 cm high.
Rubber pads are provided by Symeo (see Figure 18). The rubber pads reduce vibration
to the LPR station. Place 4 rubber pad into the drill holes ad fasten the screws.
Open the LPR-2DB Station: With a Phillips screwdriver (Size 0), loosen the top four
screws of the LPR-2DB Station lid.
Screw the LPR-2DB Station tightly to the device. The installation holes of the rubber pads
are provided for this purpose. Check that the station is mounted securely.
Close the station: Place the cover of the LPR-2DB Station on top and fasten the cover
with the four screws. Make sure that the cover is securely attached to the housing.

Installation of LPR antennas
Connection of antenna cables to the mobile units (LPR-2DB Station)
If several antennas are used, ensure that they are connected to the
correct ports.
When installing the cable, ensure that electrostatic charging does not
occur.
Make sure that the cable is not kinked or trapped during installation. The
minimum bending radius must always be maintained. With the standard
antenna cables delivered, the minimum bending radius (center of radius
to cable core) for standard cables is 10,5cm (for multiple bending under
mechanical load) and 4cm (unloaded and static bending). The cable
must not be attached in a way that alters its cross-section. On demand,
cables with different flexibility characteristics are available.
The antenna plug must not be removed (e.g. for installation purposes)
or repaired because the specified electrical properties can only be
achieved with mechanical installation assistance.
When installing the antenna cable, ensure that the screw connection is
seated properly. The antenna cable plugs should be finger-tightened
before tightening with an appropriate tool to no more than 1.3 Nm

5.3.2
Mounting of LPR antennas
The line of sight between the antennas on each unit must not be
obstructed. Therefore, when installing the antenna fixture, ensure that
no components are blocking the line of sight between the antennas. If
necessary, contact the SYMEO technical department.
If you change the position of one antenna, this will affect the
measurement data that is output.
Install the antenna fixture according to the accompanying operating instructions.
Secure the antenna in the fixture.
Connect the antenna to the antenna cable.

Notes for mounting position of LPR antennas on the mobile unit
Considering the correct mounting position of the antennas you have to take care to
guarantee a free line of sight between the antenna(s) on the vehicle and all LPR-2DB
Integral Stations.
If construction on the vehicle partly interfere the free line of sight (e.g. driver cabin), the
distance between the antennas and this construction barrier should be chosen big to make
the “blind” sector small.

On the other hand the antenna should be close to the center of rotation of the vehicle type to
make the positioning error due to the rotation of the vehicle as small as possible (see Figure
24).
The position of the antenna(s) is in some cases a trade-off between minimizing the error due
to construction barrier on the vehicle and the minimizing the rotation error. Contact Symeo if
there are questions regarding the installation position of the antenna.
If a second antenna is used on the vehicle the distance to the first antenna should be at least
1 meter to calculate an orientation of the vehicle. The orientation is necessary to determine a
load position if the antenna is not mounted above the load position.

Figure 24 – Mounting position of antenna
Depending on the position of the LPR-2DB Integral Stations different minimum system
ranges result. The system range depends on the selection of the antennas and the antenna
cable length as well as of the antenna cable length. In general the antenna cable length on
the vehicle should be as short as possible to minimize the signal loss in the cable.

6 Coordinate System
The LPR-2DB Integral Station and the antennas of the mobile stations must be surveyed.
6.1
Survey Instructions for the LPR-2DB Integral Station
The Integral Stations are supplied already preassembled (hood + base) and with the bracket
separate. Figure 25 shows various views of the assembled LPR-2DB Integral Station
including the mounting bracket
Figure 25 – Complete LPR-2DB Integral Station including mounting bracket
6.1.1
Coordinate system of LPR-2DB Integral Station
The accuracy of the position output depends in large part on the exact recording of the
positions of the LPR-2DB Integral Station. Accordingly, the positions of the installed stations
must be calibrated to a tolerance of +/- 2 cm (in each direction). At the same time, the
orientation of each Integral Station in the x-y direction is also recorded. The inclination of the
stations is not recorded.
LPR works with a Cartesian coordinate system, which is spanned by the x-y plane (see
Figure 9). The positions of the Integral Stations are identified in this coordinate system. By
default, the coordinate system has a positive effective direction.

Figure 26 – transponder coordinate system
Positions in all four quadrants can be measured in the transponder coordinate system: LPR
calculates the 2D position in the plane spanned by x and y.
Since it is not always possible to mount all the LPR components (LPR-2DB Integral Station,
LPR-2DB Station antennas) in this plane, the deviation of the installation position in "z"
relative to this plane must be specified for all LPR components.
In plane areas the z-position can be estimated directly towards the ground level.
The LPR-2DB Integral Stations must be measured in x-/y- and z-direction.
6.1.2
Reference point of LPR-2DB Integral Station
The position of the measuring point is critical for measuring the LPR-2DB Integral Station.
The measuring point is marked by matting on the stations housing.
In a top view, the measuring point is located at the same level as the antenna patches
(horizontal structures, roughly in the middle of the board portion above the copper reflector).
In the front view, the zero point is located midway between the copper reflectors.

6.1.3
Orientation of LPR-2DB Integral Station
The alignment of the stations is recorded as a vector in the coordinate system that is defined
for the application, and is entered as an ex/ey value. Integer values are possible for ex/ey.
The following diagram illustrates this principle (corresponding negative values for an opposite
alignment).

It is also possible to compute the orientation vectors from the angle of the integral station in
the plane:
Figure 30 – Computation of ex/yx from angle a
Hereby is ex = cos(a) and ey = sin(a).
So just compute the values and multiplicate with 10 and truncate the decimal place:
Example: a = 12°, 10*cos(a)=9,78; 10*sin(a)=2,08 ex = 9; y = 2

9 Network Settings
Having a LPR station with TCP/IP interface the network settings for this station are described
in this chapter.
Therefore it is necessary to open a TCP/IP connection between your computer and the LPR
station.
9.1
TCP/IP connection between PC and LPR-2DB station
With delivery the LPR-2DB stations have the fixed IP-Address
192.168.1.99.
You can change the IP-Address of the LPR-2DB Station via the web interface of the LPRStation (see chapter 9.3).
To get a connection between your PC and the mobile station it is maybe
neccessary to change the network parameters of your computer. Both
units must be located in the same network. That means in this example
that the first three numeric pads of both IP-addresses must be the
same.
Disconnect your PC from the network. Connect the LPR-2DB station and the computer with a
network cable. Open your network settings of your computer.
Enter the following fixed IP-Address i.e.
192.168.1.1. The subnet mask should be set
to 255.255.255.0.
Click in both windows OK.
If you firewall settings are too restrictive, you may not get access to the
LPR-1D station. In this case temporarely deactivate the firewall under
the tab „Advanced“ in the dialog window “Network settings”.
The LPR-2DB Station should be available via your PC now. You can check the connection
with a „ping” to the LPR station:

10Symeo 2D Protocol
10.1 Introduction / Basics
The Symeo 2D protocol is the interface between the LPR 2D system and the user. To keep
the protocol simple (i.e. easy to parse) the following aspects are considered:
consistent data packet
The protocol has a standard data packet with a fixed length.
configuration
The structure of the protocol can be configured by the user. It is possible to output only
the required data. Therefore you can use also a slower data interface when using less
data.
The protocol is unidirectional. The LPR 2D system sends data to the user, but the LPR 2D
system does not receive any data from the user.
You can choose between the binary format and the ASCII format. The formal structure of
both protocols is the same.
10.1.1 Configuration file Symeo_2D.ini
To configure the protocol you have to set the parameters in the configuration file for the
protocol (Symeo_2D.ini).
Figure 57 – configuration file Symeo_2D.ini (example)
The following text must be contained in the configuration file to choose the format of the
protocol:
[format]
binary
or
[format]
ascii
Symeo 2D Protocol

Page 106 of 132
®
Symeo LPR -System
®
LPR -2DB
Product Documentation
A protocol output is sent at regular intervals - independent of the availability of a valid
position.
The default output interval is 100 milliseconds. To set another output interval (e.g. 200 ms),
insert the following parameter in the configuration file of the protocol:
[OutputInterval_ms]
200
With the default configuration (OutputOnlyLockedTracks=1 in data
field POSITION), only valid positions are sent (LOCKSTATE=2). If there
is no valid position available, no protocol output is generated – even if
other data available (e.g. system errors).
If the default configuration is overwritten
(OutputOnlyLockedTracks=0), an output is generated after each
[OutputInterval_ms] ms, even if no valid position is available. In
this case a position output of (0,0) is sent and LOCKSTATE has a value
of 0 or 1.
In some applications additional protocol output could be generated (not
only every OutputInterval_ms). If SYMEO software detects an
event (e.g. a container lift), an additional output is generated at the time
of the event.

10.2 Binary format of the protocol
For the binary format the entire data packet of the 2D protocol is transferred as binary data.
This means that the binary format is more compact than the ASCII format, but is not humanreadable.
10.2.1 Data types
The length of all data fields is a multiple of one byte.
The data types are exclusively bit field or integer. Integers can be signed or unsigned. This is
specified in the description of each integer data field. Integer data fields with a length of more
than one byte are all encoded in network byte order (Big Endian).
10.2.2 Byte Stuffing
The data packets are transmitted continuously with a constant length. The problem is here to
identify the beginning of a data packet. Although an identification character for the beginning
of the data packet is sent, exactly this identification can happen to appear in the following
data packet. Without an additional technique it is not possible to detect the beginning of the
data packet.
If the protocol is used with a TCP/IP interface, the first data packet is first sent when the
socket is connected. The first byte of the socket is always the beginning of the data packet.
Because all data packets have the same length and the transmission via TCP/IP is error
proof, it is possible to read always the same length (bytes) of data packets on the receiver
side.
If you use the RS-232 interface there is no proven failure free transmission of data. The
receiver might start reading the data at an arbitrary moment. There is no possibility to detect
the beginning of the data packet.
To use the protocol for a RS-232 interface the binary data must apply byte stuffing. When
byte stuffing is active, reserved symbols are used to identify the beginning and the ending of
a data packet. These symbols cannot be used in the regular data stream. Figure 58 shows
the principal layout of this binary packet.

If the reserved symbols are used in the data packet, they have to be substituted by the
following symbols:

0x7d 0x5d
0x7e
0x7d 0x5e
0x7f
0x7d 0x5f
Figure 59 – Substitution rules for byte stuffing
Each time one of the three exclusive symbols occurs in the data packet it is replaced by two
other symbols. In the worst case the whole data packet consists of exclusive symbols. In this
case the length of the data packet is doubled.
The byte stuffing makes sure that the receiver can identify the BINARY-START field
definitively, even if the payload data contains the reserved symbol.
Decoding the byte stuffing at the receiver side can be implemented as following:
When reading symbol 0x7d, discard this symbol and combine the next symbol via XORfunction with 0x20, which will restore the original symbol.
The byte stuffing can only be used for the binary format of the 2D protocol. It is activated per
default. If you want to disable byte stuffing you have to enter in the configuration file the
following line:
[DisableBytestuffing]
10.2.3 General Structure
The structure of the data packet of the 2D protocol is identified in the configuration file. For
one configuration all data packets have the same length and the same structure. In the
configuration file you identify the desired data fields. Figure 60 shows the structure of the
data packet for the standard configuration.
Data field
START
POSITION
END

If required additional data fields can be activated. The sequence of the activated data fields
is fixed and cannot be changed. Figure 61 shows the structure of the data packet with all
activated data fields.

10.3 ASCII format of the Protocol
For the ASCII format of the 2D protocol the entire data packet is transmitted as ASCII-code
by letters, numbers and some special characters. This means the ASCII code is humanreadable. Due to the fewer encoding characters the data is transmitted not as compact as for
the binary protocol, so the amount of data increases.
10.3.1 Data Types
Each data packet consists of characters/strings, numbers (optional with decimal point und
sign) and underline character. Each data packet consist of one row, terminated by the
special character LF (line feed \n, ASCII-Code 0x0a).
All numbers have a prescribed fixed quantity of characters. If less numbers are required for
the value, the value has to be filled by zeros.
Integer values exist as well as floating point numbers. The numbers in each data field are
described as follows:
Sign, always (+ or -)
Sign, only if value is negative (then -)
Single decimal number / character
Decimal point (only for floating point numbers)
Example:
The floating-point number to encode is: 12.34
description:
+###.####
coded number:
+012.3400
10.3.2 General Structure
A configuration file is the basis of the 2D protocol. Each data packet consists of one text row
– the end of each data packet is terminated by the ASCII-STOP sign \n (ASCII code 0x0a).
Once configured the each data packet has the same length and the same structure. The
configuration file specifies the data fields. Figure 62 shows the structure of the data field for
the default configuration:

10.4 Bit Mask SELECTED-FIELDS
The bit mask SELECTED-FIELDS is part of the data field START. It indicates which bit fields
are activated. Once the bit mask is configured, each data packet has the same length and
the same structure. Therefore the value of the bit mask SELECTED-FIELDS is constant. By
evaluation of the bit mask at the receiver side it is possible to check for plausibility of the
configuration file.
Each data field is presented as a single bit in the bit mask. If the data field is activated the
related bit is set.
Figure 64 shows the allocation of the single bits and data fields. Bit 31 is the most significant
bit and is found in the ASCII format of the protocol on the left most side.
Important: The order of bits in this bit mask does not correspond to the order of data fields in
a data packet. The order of the data fields is described in chapter 10.2.3 (binary format) or
chapter 10.3.2 (ASCII format).

10.5 CRC Calculation
To detect errors during data transmission, the data field CRC can be activated. For CRC the
CRC-16-IBM is used with the polynomial x16+x15+x2+1. The CRC is applied to all previous
data fields of the data packet except the data field START.
Example source code for CRC calculation in C:
// Holds a table to calculate crc16 values
static Uint16 crc_table[256];
// Initializes the CRC table
// MUST BE RUN before first crc calculation
Void InitCRCtable( void )
int i, j;
Uint16 k;
for (i = 0; i < 256; i++)
crc_table[i] = i;
for (i = 0; i < 256; i++)
k = 0xC0C0;
for (j = 1; j < 256; j <<= 1)
if (i & j)
crc_table[i] ^= k;
k = ((k & 0x7FFF) << 1) ^ 0x4003;

return crc;
10.6 Error Codes
If the system identifies self-contained an error (self-diagnosis), a system error is sent. The
error is sent as long as the error is not repaired. I.e. if a broken transponder is recognized as
broken then the appropriate error code is sent until the transponder is able to make a correct
measurement.
A special case is the error code 0xff. This error is sent if more than 5 errors appear at the
same time. Therefore not all error codes can be transmitted. This special error code is only
sent for the last error code of the system failure (ERROR-CODE-5).
An error consists always of the error code. Optional it can feature an error value which
consists of additional information to the error code.

10.6.2 Error codes
10.6.2.1 0x01 – broken TDOA cell master
If a TDOA cell master is broken, no measure commands are sent to the transponder of the
cell. If a transponder doesn't receive a measure command, it broadcasts an IDLE message
Symeo 2D Protocol

Symeo LPR -System
®
LPR -2DB
Product Documentation
once per second. But this can also happen if the line of sight between cell master and a
single transponder is broken (e.g. an obstacle between in the line of sight).
To detect a broken master, we count the number of IDLE messages of a single cell in the last
60 seconds. If we receive at least one IDLE message of at least two different transponders
during this time and received no valid transponder measurement during the observation
interval and the oldest IDLE message is at least 30 seconds old, we assume the cell master
is broken.
The error value contains the cell ID of the broken master.
10.6.2.2 0x02 – broken transponder
If a single transponder is broken, it is not measured by the base station, so the basestation
measures only the remaining transponders of a cell. But such failures can be position
dependent, so we have to check, if a transponder isn't measured at several positions of the
basestation.
To detect a broken transponder, we count the number of “positions bins”, in which the other
transponders of a cell was measured. A “position bin” is a square of 5x5 meter. If at least
50% of all cell transponders were successfully measured in at least 5 position bins (per
measured basestation antenna) and the observed transponder was not measured in any
position bin, we assume the transponder is broken.
The error value contains the LPR-B address (see chapter 10.6.3) of the broken transponder.
10.6.2.3 0x05 – broken LPR antenna
To detect a broken LPR antenna, we count the number of “positions bins”, in which we
measured another LPR antenna. A “position bin” is a square of 5x5 meter.
For the detection at least one LPR antenna must be measured at 10 “popular places” in the
last 10 minutes. A “popular place” is a position bin, visited for at least 10 times. If the
observed LPR antenna was never measured at any popular place, we assume the antenna
is broken.
The error value contains the antenna port of the broken LPR antenna. If the mapping of
antenna ports is not configured, the error value is set to -1.
10.6.2.4 0x06 – broken hardware component
The software FusionEngine communicates with the attached hardware components (sensors
etc.) via different interfaces (e.g. RS-232, TCP sockets etc.). If an communication timeout
occurs at one of these interfaces, the respective hardware component is marked as failed.
This error code can also caused by wrong FusionEngine configuration.
The error value contains the index of the concerned FusionEngine node. To find out the
hardware component of a FusionEngine node, the FusionEngine logfile must be analyzed.
