RFID is applied to FAW-Volkswagen AGV cars

Cooperating with FAW-Volkswagen Co., Ltd., RFID technology was applied to the project of 96 AGV cars in the Qingdao assembly workshop of FAW-Volkswagen to solve the problem of fixed-point positioning of the cars. The central control system identified the ground RFID tags read by the RFID sensor on the AGV car chassis. Data, through algorithm calculation and comparison of tag data, the AGV car can be positioned at a fixed point, helping FAW-Volkswagen reduce costs and improve efficiency.

Domestic development of AGV cars

Nowadays, our country is facing problems such as the imminent loss of demographic dividend, sharp rise in labor costs, lack of well-trained industrial workers, and difficulty in recruiting workers. These problems have given rise to a strong driving force for the rapid growth of demand for intelligent manufacturing. Intelligent manufacturing is playing an important role in the field of automobile production. Due to its development and growth, many companies and colleges have realized that intelligent manufacturing can save manpower, improve work efficiency and save costs.

AGV intelligent handling systems have become a necessity for manufacturing production in many cases. In addition, the products of leading domestic companies have superior cost performance. As the cost pressure of manufacturing companies increases, AGV trolleys will become one of the few ways to improve the level of enterprise production automation. It is an effective means to reduce labor costs.

The application of RFID technology to AGV cars can solve problems such as the difficulty of fixed-point positioning of the cars, help staff understand the specific location of the cars in real time, facilitate management personnel to make deployments according to production conditions, effectively reduce labor costs and improve production efficiency.

Agv car fixed-point positioning technology

The technical difficulty of AGV cars lies in navigation and positioning technology. Currently, the commonly used ones on the market are: laser induction type, electromagnetic induction type, machine vision type, inertial navigation type, etc. Each of these technologies has its own advantages and disadvantages, and some technologies may require major modifications to the factory environment to achieve high-precision positioning.

The RFID sensors developed by our company are simple to install, have low environmental requirements, can adapt to respective harsh industrial production conditions, and can perfectly help solve fixed-point positioning problems, help the AGV system accurately locate the car, and facilitate managers to control the car and issue instructions to the car. .

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.

RFID sensors have the advantages of good anti-interference ability, strong environmental adaptability, and long communication distance. The cooperation between RFID and FAW-Volkswagen Qingdao Assembly Plant is a successful case of RFID technology application and automobile assembly industry. Nowadays, RFID has been widely used in AGV cars, warehouse management, assembly line production, etc., with mature product solutions.
