Problems solved by technology
[0003] At present, the ordinary ranging method adopted in China does not specifically measure the RFID reading range in the gate entrance environment. Therefore, the ordinary ranging method cannot realize the distance between the ranging sensor and multiple RFID antennas, tags, readers, and cargo conveyor belts. multi-party interface control

Embodiment Construction
[0019] Taking the pallet-level RFID entry and exit gate application detection system as an example, the RFID antenna uses Larid A9028 far-field antenna, and the maximum reading distance is about 15m. The RFID reader selects Speedway Revolution R420 UHF reader from Impinj Company of the United States. The ranging sensor chooses the X1TA101MHT88 laser ranging sensor from Wenglor Company in Germany, and the measuring distance range of this sensor is 50m.
[0020] When the RFID antenna power is adjusted to the maximum, the RFID reading distance should be about 15m. At this time, the RFID reading range automatic measurement method proposed by the present invention is adopted, and the method mainly includes the following five steps:
[0021] Step 1: Simulate the delivery of goods in and out of the warehouse. Set up a pallet on the cargo conveyor belt, place the cargo on the pallet, install a reflector on the cargo, set the lifting height of the pallet to 1m and the transmission spe...
