ABSTRACT
The topic "design of material trolley control system" comes from the needs of actual industrial applications, especially in the fields of automatic production line, material handling system and warehousing logistics. With the improvement of industrial automation, the efficiency and accuracy of material transportation are also more and more high. Therefore, it is particularly important to design a control system that can efficiently and accurately complete the task of material transportation.
This paper aims to design and realize a material transport trolley control system, which is based on the combination of electrical control principle and PLC programming technology. The system drives the car left and right through the three-phase asynchronous motor, and uses the photoelectric switch to accurately monitor the position of the car at the five docking points. The car has the ability to respond to the call button command. According to the comparison between the current stop station and the call button coding, it can automatically select the running direction and dock accurately. The system design includes the drawing of electrical schematic diagram, PLC program writing and system debugging, aiming to cultivate the ability of system analysis and design. The experimental results show that the system can realize the automatic control of trolley, meet the material demand, and have good stability and reliability.
