| Abstract: | Measuring the RSSI value of a RFID electronic tag can be used in industrial control as a kind of locational sensing technology, so as to expand the application area of the RFID. This paper mainly introduces the MODBUS agreement transplants on the MSP430 to achieve the communication between PLC and RFID electronic labels under the MODBUS agreement. Practice has proven that using this communication protocol in automatic loading and unloading control system of the train canimprove the fix position precision of the system and make it more effective. |
