Problems solved by technology

[0002] The communication interfaces between existing scales and other equipment are mainly CAN bus, RS485 bus, RS232 serial interface or Ethernet interface, while existing computers gradually cancel the parallel device interface and serial device interface, and only retain the current common Ethernet interface and USB interface, and the wiring of the parallel device interface is complicated. The RS232 serial port device needs to install the serial device driver on the computer side or use the USB virtual serial port, and it is necessary to set the corresponding communication parameters according to the characteristics of the device, and the serial port is based on the The connection communication method has poor communication stability, and the number of computer Ethernet communication interfaces is small, the protocol layer is complex, and the implementation and application are difficult
