RFID combined with AGV car information data management

The AGV intelligent handling system has become an important technical means for manufacturing production. With the diversification of manufacturing enterprises, AGV trolleys have improved the level of enterprise production automation and enabled fewer people to operate. RFID technology is applied to AGV cars to make data collection more intelligent and information-based, allowing the cars to be positioned at fixed points, making it easier for managers to make deployments based on production conditions, effectively reducing labor costs and improving production efficiency. The application of RFID information data management is combined with the use of AGV cars. RFID combined with AGV car information data management greatly improves the corresponding work efficiency!

The RFID Card reader is installed inside the car. The card reader integrates free protocol and modbus communication protocol. Our company provides high-quality after-sales service to ensure that all kinds of problems encountered by customers during the installation project (such as product debugging, equipment installation, sensor selection) are solved. type, etc.). The AGV car walks on a prescribed path and installs a tag every short distance. The RFID reads the tag data and uploads it to the system. The system can then locate the car at a fixed point through algorithm comparison. The AGV car has a high degree of automation. When auxiliary materials are needed in a certain link in the workshop, the staff inputs relevant information into the computer terminal, and the computer terminal then sends the information to the central control room. The central management or manager holds a tablet to issue instructions to the computer. With the cooperation of electronic control equipment, this instruction was finally accepted and executed by the AGV - delivering the auxiliary materials to the corresponding location.

Advantages of RFID technology:

(1) It has strong penetrability and can easily penetrate objects to read tags without affecting the reading range;

(2) Strong anti-interference, other frequency band technologies are susceptible to interference from factors such as environmental humidity, noise, oil pollution, electromagnetic fields, strong vibrations, etc., and are prone to unstable card reading, resulting in data packet loss or failure to read tags. Chenkong AGV card reader Not easily disturbed and well able to avoid these problems;

(3) The card reading distance is moderate and stable. To achieve accurate parking, the AGV sensor (i.e. card reader) must have a stable and reasonable card reading distance. A reading distance that is too close means that the AGV chassis needs to be very low, which will undoubtedly increase the equipment failure rate; a reading distance that is too far means that the positioning is inaccurate, and the robot has read the tag and stopped before it reaches the site.

(4) The card reading speed is fast, and the stable tag reading speed reaches more than 2 meters/second. When the AGV is accelerating, the tag will not be read when the ordinary RFID Reader cannot read the electronic tag;

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. ; AGV reads ground signs through RFID and makes corresponding actions (change 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 host computer The machine's instructions are used to control the car.

The application of AGV unmanned trucks in the industry has greatly improved the level of automated production, improved production efficiency, saved manpower, material and financial resources, created a human-machine friendly production environment, and established a good corporate image.
