To understand the application of RFID in AGV automatic transport vehicles, we must first understand what AGV is. AGV trolley refers to a transport vehicle equipped with electromagnetic or optical automatic guidance devices, capable of traveling along a prescribed guidance path, with safety protection and various transfer functions. As an unmanned industrial handling vehicle, high-speed, high-efficiency and accurate positioning are very important for the AGV trolley transportation system.RFIDIt has the advantages of non-contact, non-line-of-sight, etc. Using RFID to control the positioning of the AGV trolley, compared with other positioning methods (inertial positioning, ultrasonic positioning), not only has a simple structure, low cost, but also is easier to implement and can accurately locate.

The specific application of Jianyong Technology’s long-distance high-speed RFID positioning technology
Automation, informationization, and intelligence have become the needs of the development of the times. Since the beginning of the 21st century, wireless technology and computer technology have continued to develop in depth, and the Internet of Things industry is booming. RFID radio frequency identification is a non-contact automatic identification technology, which automatically recognizes the target object and obtains related data through radio frequency signals. The identification work does not require manual intervention and can work in various harsh environments. With these characteristics of RFID, the use and value of RFID positioning technology integrated in AGV are very great.
A method of using RFID in AGV
A low-frequency and long-distance RFID card reader system is installed on the head of the AGV to connect with the AGV data system.Then install an electronic tag at the track node, and assign an ID number and definition to the electronic tag on each node. For example, node A represents the AGV turning, which is represented by ID number 00001. Once the transport vehicle passes through A, RFID The card reader system will read Aelectronic labelID number, and make the corresponding turning action according to the specific instruction of the ID number. The same principle applies to AGVs at nodes such as acceleration and bifurcation. As shown below:

Second, the advantages of long-distance high-speed RFID positioning technology of Jianyong Technology
1) Jianyong Technology’s long-distance RFID low-frequency technology can read electronic tags at a distance of more than 20cm, which is almost double the reading distance of ordinary RFID low-frequency technology. Installed on the AGV, it is more convenient to read the RFID electronic tags on the track, reducing the occurrence of loopholes or not being able to read the tags due to distance problems.
2) The low-frequency technology of Jian Forever Distance not only has a long reading distance, the reading speed of the tag is up to 2 m/s, and the reading is very stable. When the AGV is accelerating, when the tag is read, the electronic tag will not be read by the ordinary RFID reader.
