2 RFID System Physical Anti-Collision Experimental Verification
meet the needs of large warehouse logistics enterprises, but the cost is high, which
is not suitable for the laboratory research system.
In order to explore the overall performance of the tag group in the process of
movement, the test system needs to complete the task of obtaining the recognition
distance of the tag group in the process of movement and collecting the distribution
image of the tag. With the system of goods entering and leaving the warehouse as
the model, RFID tags are attached to the goods. When the goods enter and leave the
warehouse, the system collects the goods information in real time. Therefore, the
design of the test system needs to simulate the process of goods in and out of the
warehouse, data collection and information processing. In the system designed in this
paper, the reader can transmit power-adjustable range, can complete long-distance
dynamic test, and can collect the tag image, the cost is low and easy to disassemble,
convenient for the use of the tag group performance expansion research. This system
makes up for the deficiency of the previous test system, the function is more advanced
and perfect.
The dynamic test system designed in this study includes reader antenna, laser
rangefinder, CCD camera, drive motor, RFID reader, reflector, guide rail, optical
lifting platform, data display, and computer. The system structure is shown in Fig. 2.1.
In Fig. 2.1, the guide rail and driving motor are used to simulate the process
of entering and leaving the warehouse of goods, and the reflector plate is used to
simulate the surface of goods. The reader antenna, RFID reader, laser rangefinder,
and CCD camera are used to simulate the data acquisition module. Computer and data
display for data processing. The reader antenna, laser rangefinder, and CCD camera
are located at one end of the guide rail and can be set horizontally by an optical lifting
platform. Among them, the reader antenna is used to transmit and receive microwave
