MINORPLANET AEMB100 Base Station AVL & Data Logging System System Overview & Installation Guide AEMB100 Base Station WM1003 Issue 1
MINORPLANET 1. OPERATION 1.1 Maptrack System Overview The Maptrack system brings together satellite based global positioning technology, microprocessor control, low power radio and international GSM communication infrastructure to achieve wide area communication, vehicle location, telematics and communication services. 1.1.1 Operation Overview 1.2 System Overview The AEM3000 is an electronic data collection and transmission device, incorporating GPS tracking and GSM communication technologies. Whilst the vehicle is in use, geographical and operational data is continually monitored and recorded within the DCU (data collection unit) memory. Up to 8 weeks of operational data can be held within the DCU. If the memory capacity is reached before the data is downloaded, the oldest records will be lost as new records are recorded. Recorded data may be downloaded for processing by the base computer in the following ways; a) bulk download of all held data via the GSM data channel b) snap shot of current ‘live’ data via the GSM SMS network. c) bulk download of held data via the FCC compliant low power radio interface upon return to base. Interrogation of the DCU is possible anywhere that benefits from GSM network coverage (subject to roaming agreements with GSM networks). AEMB100 Base Station WM1003 Issue 1
MINORPLANET 1.3 System Operation The Maptrack in-vehicle system consists of the DCU (data collection unit), GPS, GSM and Low Power Local Download antennae. Only power and ignition connections are made to the vehicle electrical system. When an ignition signal is present at the DCU the system records a start event and activates the GPS receiver, the vehicles geographical position, velocity and distance travelled are then continually recorded within the DCU until the ignition signal is removed, at which time a stop event is recorded, the DCU then performs any outstanding tasks before powering down the GPS receiver and GSM transceiver. When the vehicles ignition is turned off, the low power radio will power up and transmit a ‘Come And Get Me’ (CAGM) packet. If the vehicle is within range of its AEMB100 Base Station this packet will be received by the Base Station, which will request a transfer of data from the Vehicle to the Base Station. This transfer of data is via the Low Power Radio link in a half-duplex packet format. 1.4 AEMB100 Component Layout AEMB100 PCB Assembly AEMB100 Internal Wiring Radio Packet Controller Detail AEMB100 Base Station WM1003 Issue 1
MINORPLANET 2. SAFETY STANDARDS The AEMB1000 Base Station and associated equipment has been fully EMC tested to VCA recommendations in accordance with European Directive 95/54/EC, Annex 7 & 8 (emissions). 2.1 Low Power Radio Antenna Element The low power radio contained within the AEMB100 Base Station is designed to comply with FCC directive part 15. As such only aerials approved and supplied by Minorplanet may be used in conjunction with this product. It is forbidden to use any antennae other than those verified and approved by Minorplanet. Both the AEMB100 Base Station and its associated antenna must be installed, and/or protected, in such a way that they will be inaccessible to normal pedestrian traffic after installation. 3.
