| The work aims to realize the automatic control of the batching weighing process and the real-time monitoring of the data, and improve the production efficiency of the batching link and the weighing and packaging precision. The automatic weighing batching control system based on DeviceNET fieldbus was designed. The core of the control system combined OMRON CJ1M-CPU13 PLC, power supply, I/O and other modules to achieve the automatic control of weighing and batching process. The data of remote weighing instrument were acquired through the DeviceNET fieldbus, and then transferred to the lower computer PLC by the bus for the processing, and all kinds of control commands were sent by the PLC. The management-level PC and the PLC communicated through Ethernet. The experimental results showed that the proposed control method could effectively improve the weighing batching precision, and the weighing error could be controlled within ±3 g. The control system has the advantages of strong stability, low cost and strong programmable ability. It greatly improves the batching weighing precision, and realizes the real-time monitoring of data. |
