[Abstract]:The advance of German industry 4.0 marks the arrival of the fourth industrial revolution, which is dominated by intelligent manufacturing, and has a great impact on the development of tobacco machine equipment control system. With the application of man-machine interaction system, expert system, remote monitoring and operation of equipment, cigarette machine equipment is developing towards the direction of intelligence while realizing automation. This paper takes the control system of the tobacco machine equipment as the research object, on the basis of the unified electronic control platform put forward by the Zhongyan Technology Center, using the development idea of the rapid prototyping model, combining the control technology based on PC and the Ether CAT communication technology. The control system of cigarette machine equipment is constructed, which lays a foundation for speeding up the research and development process of unified electronic control platform and realizing the research of intelligent control system. Firstly, this paper summarizes the research status and development trend of the control system, analyzes the control system of the domestic and foreign tobacco machine equipment, and introduces the unified electronic control platform proposed by the China Tobacco Technology Center. Then, according to the technical requirements of the unified electronic control platform and the main control function requirements of the tobacco machine equipment, the structure of "IPC embedded PC" is adopted, that is, the upper computer adopts the single IPC, motion controller and the German BECKHOFF embedded PC.. At the same time, according to the requirement of real time, the function of the system is divided into upper computer management module and lower computer control module. Hardware is the carrier of the system function. The control system is mainly composed of upper computer, main controller, communication module and I / O unit. In order to realize the function of the system, the overall hardware frame of the control system is determined, and the main control modules of the system are designed. Based on the comparison and analysis of the principle and performance of typical industrial real-time Ethernet technology, the communication mode between the devices is determined. This paper analyzes and tests the principle and method of communication between host computer and Twin CAT soft PLC, PC and Oracle database, compiles the PLC control program of lower computer, and develops the upper computer management module of control system with VC, including software structure and man-machine interface. Part of the functional interface, and so on. The professional database is used in the control system to realize the data storage, analysis and processing. Finally, on the basis of the hardware platform of the laboratory, the experiments of servo motor control, temperature control and database communication are carried out. It is verified that the control system studied in this paper can meet the requirements of the servo motor control I / O terminal input and output control and communication with the database.
