reader RF unit fundamental block diagram
reader baseband unit fundamental block diagram
3.1.1 RF unit:
→The RF unit receive baseband signal and modulate carrier,then amplify the
modulated carrier signals and transmit the signals by selected antenna.
→The unit receive the back scatter signal from the RFID tag.After demodulating ,
amplifying ,comparing the signals ,the unit transmit the signals up to baseband unit.
→The unit adjust output power and frequency of the antenna interface under the
control of the baseband unit.
3.1.2 Baseband unit:
→The unit receive data & command from PC via RS-232 interface,or send data &
results to PC ;
→The unit transmit control signals of tags to RF unit;
→The unit accept tag signals from RF unit, modulate signals and
checkout;
→The unit can modify or query configure information of reader under the control of
PC command ;
3.1.3 Power unit:
→converts incoming alternating current (AC) to direct current (DC),out DC power
supply for the integrated equipment.
3.1.4 Data interface unit:
→Standard connector to connect the COM port ,network and power interface with
the rear panel of the integrated equipment ;
3.1.5 Case unit:
→The reader case is made of molded-in Aluminum.
3.2 Fundamental working principle
The complete RFID system is consist of XCRF-502C reader, antenna, tags, and
pc.
The baseband send the command to RF unit under the control of PC.RF unit
send signals to tags according to the tag type. When the tag is activated, it sends out
its number as well as other information .
The tags' response signals was amplified and shaped by the received-data
circuit. Then the signals was send to baseband unit. The baseband will decode the
received signal and then sends to PC via the communication interface of the
baseband unit.
The transmitting part of the RF unit will take the function of carrier generation,
carrier modulation, amplification and emission. The receiving part of the RF unit
will take the function of demodulation, amplify , compare
etc.
The FPGA part of baseband will take the code/decode function to tag data.
MCU will take the function of communication with PC.
4 Usage and operation
4.1 Reader connection
There are 2 antenna port on the XCRF-502C reader .The output port of antenna
interface is N plug.
4.2 Reader usage and operation
Connect the device as stated above, and the reader will work under the control
of PC command. Our company provide API function and reader
demo
software .User can use the software to test the reader. Please read user manual of the
reader demo software to get the information about test procedure and test method.
5 Usual failure analysis and exclusion
·When the reader is power on the signal lamp is not lighted:
→power fault: check if the input alternating current power is normal. The
alternating current voltage should between 100V～240V;
→If the other signal lamp is light, there is MCU or FPGA fault in the device. Once
you meet this problem, you can only contact with Invengon company to repair the
device;
·Can't read tag data:
→Please check if the serial port or the network cable is connect to the reader
correctly. If the cable is not joint firmly, reader can not get command from PC.
→If the power amplifier signal lamp is light ,user need to check if the antenna N
connector is screw down, or if the tag is fault. But if the power amplifier is not
light, maybe the FPGA or MCU is fault. User should contact Invengo
company
to repair the device;
6 Other notice
6.1 Production warranty
The warranty: period of our products is 2 years from delivery . If a defective is
found due to material processibility qualified problems of the product , we will
perform warranty commitment. Invengo company will decide whether repaire or
replace the fault product with certain qualified problem.
If a problem occurred is because the user's operation environment is not accord with
the product Specifications, or a problem occurred due to installation reasons, we will
not perform warranty commitment. we may charge the maintenance costs.
6.2 Safety note
When reader is working (emitting microwave),person who install or operate
the device should be 30cm away from antenna to meet the FCC safety standards
requirement about maximal tolerant radiation human body can take.
The item should be carry out when user install or operate the reader.
Not undertake item:
Any RF device, include this reader , maybe disturb the medical device without
correct protection. If you face this problem , you should listen to the counsel of
medical device manufactory . This reader may disturb other device when working .
