Industrial RFID Application Technology (14): Decrypt the core of AGV | Smart RFID and magnetic navigation technology to achieve safe driving

In recent years, domestic smart AGV trolleys have developed rapidly in the industrial manufacturing industry. AGV trolleys have gradually expanded from the automotive and other industries to food, machinery and equipment, pharmaceuticals, chemicals, freight logistics, household appliances, electronic devices and other fields. Although the smart AGV car started relatively late, its future development is promising.

The entire production process of the AGV car is very complicated, so there are certain requirements for technology, involving various technologies such as motion control systems, obstacle avoidance mechanisms, navigation technologies, and visual recognition systems. Among a series of technologies here, navigation technology is the most critical.

Chen controlled intelligent RFID application scenario for the AGV car develop a collection of RFID radio frequency identification technology and magnetic stripe in one of the AGV navigation sensors - CK-GL16, in this work the reader 134khz, supporting FDX-B standard Protocol label.

Magnetic navigation AGV positioning is accurate, path laying, changing or expansion is easier than electromagnetic navigation, and the cost is lower . FDX-B tags are durable, high protection level, and data is not easy to lose. The combination of the two gives the AGV trolley extremely high travel accuracy .

In order to facilitate customer installation and debugging, GL16 integrates Modbus RTU and Canopen two communication protocols. It can be directly connected to an industrial computer through RS232 or connected to a PLC using 485 bus and CAN bus to achieve multi-slave function.

Simply use the USB to 232 converter to connect the GL16 and the PC , and open the configuration software developed by the morning control technical team. Configuration software only need to select the corresponding Port mouth good, other do not need to set up, click on the link choose "Yes" to establish a connection with GL16.

After the connection is successful, click Scan to enter the working state. Now the editor uses an FDX-B tag and several magnets to test the sensitivity of GL16 reading. Put the tag into the GL16 sensing area and you can see the configuration software displays the internal data. Move The magnet can see that the red mark on the configuration software moves with the movement of the magnet.

Click "Configuration Communication" in the upper right corner to change the settings of GL16 , such as sensor station number, working baud rate, CAN baud rate, etc. Through this configuration software, it is very convenient for customers to use and debug. We also have professional Technical support staff will serve you.

In addition to RS232 direct connection to PC , GL16 sensor also supports parallel multiple devices using 485 bus and CAN bus. When multiple devices are parallel, the station number is used to process the device data.

The following is part of the Siemens smart200 example . After the PLC is started, enable " Always_OnSM0.0 " , the MBUS_CTRL block configures the baud rate, Port port and other equipment information, and establishes a connection with GL16 .
