RFID application in AGV automated transportation collection

With the rapid development of logistics systems, AGVs are increasingly used more and more widely, and automated AGV transportation plays a vital role in warehousing, production, and transportation. The application of RFID technology in AGV automated transportation has good environmental adaptability and rapid and accurate identification capabilities. It can ensure the efficient operation of materials without manual intervention, automatically obtain transportation status, and make work more efficient.

Install the RFID Reader/writer to the AGV car, and install the AGV landmark (RFID electronic tag) at each node of the driving track. When the AGV vehicle passes through the node, the RFID automatically obtains the material/product information that has been entered by the AGV landmark (RFID electronic tag). Guide the AGV to take corresponding actions and deal with related problems in a timely manner. RFID is of great significance in AGV automated transportation. The AGV inspection robot realizes positioning management by using RFID technology when monitoring at fixed points. By installing RFID electronic tags at important sites, when the AGV inspection robot stops at the site for inspection, it reads the RFID electronic tag information and combines it with the information it carries. Various sensors obtain status information and environmental information of inspection objects, and detect faults such as line heating and abnormal machine noise that are difficult for workers to detect.

Implementation function:

Intelligent identification of materials: By installing RFID on pallets and materials, the AGV trolley can accurately obtain information on the pallets and materials during transportation.

Automatic information transmission: The RFID reader transmits the read tag information to the background through the network port or serial port.

Automatic transportation of goods: The AGV car determines the route that the materials need to be transported and the area where the materials need to be placed by reading the labels of the materials.

Intelligent recording of goods: The AGV car can accurately record the quantity of materials transported and the number of times the materials are transported by reading the label information, making it easy to query at any time.

RFID is controlled by PLC in the AGV. The car is equipped with a wireless communication system, which can communicate wirelessly with the host computer, report its own running position and working status, execute the instructions of the host computer, and transmit the work rhythm and workload to the host computer in a timely manner. machine; AGV reads the ground signs through RFID and makes corresponding actions (changing speed, steering, positioning and parking, etc.). PLC can control the car according to the preset program, or upload the data to the host computer, and then according to the Control the car using instructions from the host computer.

The carrier of goods transported by AGV is mainly pallets. RFID technology is used for AGV goods transportation, mainly by installing readers and antennas on AGV landmark readers, and installing electronic tags on pallets or goods. Pallets and goods Information about managed objects is recorded on it. When the AGV landmark reader tranSports goods, it records the transported goods information by reading the labels on the pallets or goods. The cargo information read by the reader determines the route of the goods transportation, which facilitates subsequent inquiries and allocations.

RFID has many advantages in AGV automated transportation, which greatly reduces manual operations, reduces employee labor intensity, and improves work efficiency. RFID enables accurate data acquisition, flexible control of car activities, and efficient operation in AGV automated transportation.
