Design of Control System for Large Express Cabinet Based on PLC and Configuration Software
Abstract: This paper mainly introduces the background of the subject, the status quo of research at home and abroad, the purpose and significance of the study, the basic concept, working principle, development process and status of programmable logic controller (PLC) in industrial production. Household delivery more and more frequent the actual situation and the design of the express cabinet. This paper introduces the use, development and operation mode of the express cabinet, introduces the characteristics and usage of the configuration software, and discusses the overall framework and hardware structure of the control system in detail. This article mainly uses the Mitsubishi FX2N series PLC to control the express cabinet, expressly expresses the control request of the express delivery cabinet, designs the meet the request solution, the reasonable allocation to the input and output section, prepares the T chart, uses the existing experimental instrument to debug the control system, and completes PLC and configuration software communication between the use of PLC external hardware switch to control the configuration software simulation animation in the expected target. According to the final results analysis, with the PLC design out of the control system compared to more stable, reliable and convenient.
Key words: PLC; express cabinet control; ladder diagram; configuration simulation
