Design Of Electric Control System For Multi-function Sweeper Based On Motion Controller

The multi-functional sweeper is a new type of efficient washing and cleaning equipment,which has many functions such as road washing,road sweeping,road edge cleaning,sprayand dust reduction.With the improvement of the automation degree of the multi-function washing truck and the integration of functions,the form of the insurance relay group and the industrial field control PLC can no longer meet the needs of the product,and the CAN system is used to perform the vehicle signal using the motion controller.Acceptance and processing is the development trend of the truck electrical control system.In this article,the electric control system of ZTQ5160TXSE1J50 E multi-function sweeping truck is designed,the electric control system of the whole truck is designed by the combination of motion controller and CAN.The research and work contents are as follows:(1)Analyze the parameters,control requirements and control characteristics of key electrical components of the truck,explain and prepare the core components such as software programming and control box of CoDeSys motion controller for subsequent matching design.(2)Construction of CAN bus framework,design and application of CAN bus display integrated module.Analyze the display function requirementsealize information sharing with the auxiliary engine ECU and so on.(3)Design control box,CAN line display integrated display module and rear operation box to realize signal acquisition and signal processing and truck operation.According to the design principle of “distributed arrangement,centralized control”,the motion controller and power module are placed in the main control box,and the electric circuit is designed according to the performance.(4)The system simulation and testing were carried out using Codesys software to verify the correctness of the vehicle electrical system design.Through the software simulation test and loading experiment,the rationality of the vehicle’s electrical control strategy is verified,Further verify the correctness of the principle design of the electrical system and the vehicle’s practical performance is satisfied.The research conclusions are as follows:(1)It verifies the feasibility of the control method of “Motion controller and CAN bus”,and improves the technological advancement,reliability and cost reduction from the perspective of vehicle electrical architecture.(2)It verifies the correctness of the CAN bus information frame construction,realizes the sharing of the motion controller and the auxiliary engine ECU information message,reads the engine alarm signal,the speed signal and the oil pressure signal and simultaneously controls the speed signal to meet various tasks.(3)Through the design and physical evidence,the realization of various functions of the sweeping vehicle and the action process are carried out.The design can meet various road conditions for sweeping,dry sweeping,wet sweeping and washing,satisfying the dusty road section,the muddy road section and the ordinary road section.Work needs and different modes are selected for different road sections.
