The weighing and Filling machine is based on the field management and control system of single chip microcomputer, radio frequency card and network integration technology, which can effectively control the material filling in real time. The Filling system realizes the real-time detection of filling weight and the real-time opening and closing of the solenoid valve in the filling process, and the effective microcomputerized management of data upload. It mainly includes 89C52 MCU control part, RF card reader part, keyboard, display control circuit part, GM8125 serial port expansion circuit part, LED display circuit part, solenoid valve executive circuit part, PC database processing part.

The automatic filling machine reads the electronic label of the barrel body from the site and uploads the label code to the upper computer for identity determination. If the identity is legitimate, the following switching solenoid valve and filling work will continue. During the filling process, the effective weight data of the site will be uploaded to the upper computer in real time, which will be classified and summarized together with the electronic label code. Send data of each filling site. For a large filling system, the data transmission lines of multiple filling weights in the filling station are connected by serial bus, and the data is uploaded or exchanged by a single line, reducing the laying of lines to achieve the purpose of saving resources.
