Wireless radio frequency identification, achieving station identification of AGV transport vehicles through RFID technology 123
AGV material transport vehicle refers to a transport vehicle equipped with automatic guidance devices such as electromagnetic or optical devices, capable of traveling along a specified guidance path, with safety protection and various load transfer functions. Introducing RFID technology to automatically identify target objects and obtain relevant data, the recognition work does not require manual intervention and can work in various harsh environments. Using RFID technology to control AGV cars for station recognition, compared to other methods such as inertial positioning, ultrasonic positioning, laser positioning, etc., not only has a simple structure and low cost, but it is also easier to achieve accurate recognition.
The advantages of RFID technology application in AGV site identification
1. Real time monitoring of the working status of the AGV vehicle, recording the working information of the AGV vehicle, and timely grasping the transportation route of the AGV vehicle.
2. Quickly and accurately identify the position information of the AGV car, and be able to inspect and repair it in the event of a malfunction, reducing losses.
3. Intelligent management of AGV vehicles, achieving automated data acquisition, flexible control of vehicle activities, and efficient operation.
4. It can achieve 24-hour uninterrupted work, improve the level of production and transportation automation, reduce employee labor intensity, and improve work efficiency.
The AGV material cart is controlled by PLC and can communicate wirelessly with the upper computer, report its operating position and status, execute instructions from the upper computer, and timely transmit workload to the upper computer. The AGV body is equipped with?? Is there an RFID landmark sensor installed at the node position on the ground?? RFID Landmark Card??, And assign an ID number and definition to each landmark card on each node.

When the AGV car passes by, the RFID landmark card information is read to obtain the corresponding IP address, which can determine the current location information and complete the positioning recognition of the station. Then, based on the stored information of the RFID landmark card, the current working status is determined, and the next working status (turning, straight, terminal stop, etc.) is executed.
Recommended low-frequency RFID products for AGV site recognition: ETAG-R180. ETAG-R180, also known as AGV landmark reader or AGV reader, is a low-frequency RFID landmark reader designed specifically for industrial AGVs based on RFID technology. It is used to read AGV site landmarks (ETAG-T123), and AGV cars can perform various actions such as turning, stopping, accelerating, and decelerating based on ground landmark information. High frequency: ETAG-R320 ETAG-R320 is an AGV landmark sensor that meets IP65 protection level and supports MODBUS protocol. It can be used with different landmark cards ETAG-T383, ETAG-T353, and ETAG-T361 according to different environments/media such as indoor/outdoor/metal.
This device adopts a wide voltage design and MODBUS communication protocol, with communication interfaces such as RS232, RS485, RJ45, etc., which facilitates the connection between industrial electronic devices and makes networking more convenient.

RFID product installation precautions
1. To ensure that the RFID landmark card reader can recognize RFID landmark labels to a large extent, the RFID landmark sensor needs to be installed at the bottom of the AGV car, facing the RFID landmark on the ground track. When the AGV car passes by the RFID landmark, it reads the information of the RFID landmark label.
2. When encountering metal track nodes, the landmark needs to choose an anti metal label, so as not to be unreadable due to the influence of metal materials. The application of RFID technology in AGV vehicle station recognition has the characteristics of accurate and fast reading, strong penetration, and strong anti-interference, which can enable AGV vehicles to smoothly complete various picking, handling, and material distribution tasks.
