When I first came into contact with the AGV surface card reader, the editor was also at a loss. In fact, automated storage and transportation have also been widely used in manufacturing companies, including AGV automated transportation, unmanned forklift transportation, etc., but how to control it AGV transportation and recording of transported goods have become a difficult problem. With the introduction of RFID technology, the labor loss and cargo loss in various production enterprises have been greatly reduced. The following editor will introduce some application knowledge about the AGV surface card reader and RFID equipment launched by Shanghai Haobin?
1. First, let’s talk about why RFID equipment is used on the agv landmark reader in AGV:
AGV refers to equipment Automatic handling trolleys with electromagnetic or optical guidance devices, transport vehicles with safety protection and various transfer functions. As an unmanned industrial handling vehicle, high-speed, efficient and accurate positioning is very important for the AGV landmark reader transportation system. Using RFID to control the positioning of agv landmark readers, compared with other positioning methods (inertial positioning, ultrasonic positioning, laser positioning, two-dimensional code positioning, etc.), not only the structure is simple, the cost is low, and it is easier to achieve accurate positioning.
AGV is controlled by PLC, single-chip microcomputer or motion control board. AGV is equipped with a wireless communication system, which can communicate with the host computer wirelessly, report its operating position and working status, execute the instructions of the host computer, and transmit the work beat and workload in time To the host computer. An agv landmark card reader is installed on the bottom of the AGV body, and RFID electronic tags (landmark cards) are installed at the nodes on the ground, and the landmark cards on each node are given an ID number and definition.
The agv landmark card reader reads the RFID landmark card on the ground through RFID, and makes corresponding actions (change speed, select track, positioning and parking, etc.). For example, at node A, the representative AGV needs to select the track to turn, which is represented by ID number 00001. Once the transport vehicle passes by A, the AGV card reader will read the electronic tag ID number at A, and the AGV controller will make the trolley take corresponding actions according to the read data, thereby realizing the AGV dispatching system function and site positioning function .
2. Program composition
The carrier of AGV transportation goods is mainly based on pallets. RFID technology is used for AGV goods transportation, mainly by installing readers and antennas on the agv landmark reader, and installing electronic tags, pallets and goods on the pallets or goods. The information of the managed object is recorded on it. When the agv landmark reader transports goods, it records the information of the transported goods by reading the label on the pallet or the goods, and determines the route of the goods transportation through the goods information read by the reader, which is convenient for later query and allocation.
RFID electronic label : Used to identify cargo information;
RFID antenna : Used to transmit and receive radio signals;
RFID car reader : Used to collect tag data and feedback the collected information to the background, specially designed for vehicle use; RFID card issuer: used to write tag data and change tag data; RFID handset: used to collect tag data and The collected data is fed back to the background for later inventory; for agv landmark card readers, forklift transportation can use professionalRFID reader UR5306 , Adopting overall anti-vibration and waterproofing, to provide users with more stable and reliable physical and electrical connection methods, suitable for all kinds of harsh industrial environments, and provide new RFID solutions for intelligent unmanned storage.
Through the above introduction, many readers and friends have a certain understanding of the application of agv landmark reader and RFID products launched by Shanghai Haobin. Automation, informatization, and intelligence have become the needs of the development of the times. Since the beginning of the 21st century , Wireless technology and computer technology continue to develop in depth, and the Internet of Things industry is thriving.
