The built-in communication of the formula Electronic scale is RS-485 (MODBUS-RTU) interface, while the serial communication port of the PC is RS-232C interface. Communication between the two requires an SC-09 adapter cable. The electronic scale uses the RS-232C standard to transmit signals through the voltage difference between the signal line and the common ground wire, using a unidirectional transmission method; The RS-485 standard utilizes the voltage difference of signals between transmission lines for transmission, and adopts a differential transmission method. The SC-09 cable enables the conversion between these two different signal transmission methods. The electronic scale picks up weight through the pressure weighing module, amplifies and filters the picked up weight signal, and then enters the A/D converter for analog-to-digital conversion. It is then sent to the weighing instrument for signal analysis and processing. The results are output to the industrial control through the RS232C communication port, and corresponding reactions and operations are performed based on the signal results. The ingredient distribution control method is adopted, which connects one host and multiple slaves through a network, and the host hands over the control tasks to each slave to complete. The entire industrial computer ingredient is divided into industrial control electronic scales and weighing instruments. In order to control personnel's direct and accurate raw material weighing data, the production process cannot have small quantities, shortages, or shortages of materials. Implement manual or automatic selection of bin number positions, automatic alarm of various ingredient inventory levels, and other functions. The digital display of the electronic scale is exchanged with PLC and touch screen for information exchange. All system controls will be collected on specialized system software. The controller only needs to click on the corresponding position to control functions such as electrical switches, rotating transportation components, water and gas valves, etc. The human-machine interface displays the entire production line in the form of dynamic and static graphics on the computer screen, allowing workers to understand the operation of the entire production ingredient without leaving their homes.
