Abstract
In order to reduce labor intensity, ensure the reliability and safety of unfamiliar production, reduce production costs, improve the operation efficiency and economic benefits of products is a major problem that enterprises must face. With the rapid development of China's national economy and the continuous progress of science and technology, more and more enterprises have put forward more requirements for the control system of container rail cranes, paying more attention to the work efficiency and safety performance of container rail cranes.
This design is based on the control idea of MCGS and PLC to study and design the monitoring system of container rail crane. The design of programmable logic controller (PLC) was introduced, determined the use of Siemens PLC model, used as a container rail crane monitoring system of the lower machine; Determine the PLC communication mode, and the container rail crane related control programming implementation. The MCGS configuration software is introduced, and the model of MCGS is determined, which can be used as the touch screen of man-machine interface. The communication mode between PC and PLC is determined. Using preinstalled MCGS configuration software to design the monitoring interface of container rail crane monitoring system. In order to understand the monitoring effect of the designed monitoring system in the actual application state, we choose to test through experiments, and implement automatic alarm and automatic protection for abnormal situations, realize the electromechanical integration of enterprises and improve the production efficiency of enterprises.
Key words: Container rail crane; The MCGS. PLC; The monitoring system
