[Abstract]:This paper studies a set of air compressor control system. As a kind of power output equipment in industrial production, air compressor is widely used in various production environments. At present, the stability, accuracy and real-time of air compressor output pressure are not high in most production environments. However, with the fine management of modern industrial production, many factories are demanding more and more air compressor system. In order to improve the high precision, low energy consumption and rapid response of air pressure control in production line, the system emerges as the times require. The design of the system is based on the project requirements. Through structured modeling, the whole control system is divided into input and output module, air compressor control module, sequential switching module and communication module. Separate cylinder PID regulation module and alarm module. In order to facilitate user operation and management, the man-machine interface of the system is developed with Wincc and can run stably on the Windows system. The HMI (man-machine interface) can be used to remotely control all kinds of devices under the control of the system, which is more safe and efficient than the traditional manual meter reading. The system also has historical query function and trend analysis function, which provides an effective analysis method for production analysis and process management. The system design has the following three key tasks: 1. The structural programming idea in software engineering is applied to the development of PLC project, which shows many advantages in the process of the project. Such as simple and clear program structure, easy to modify the program and system debugging, for the end of the project to save a lot of time. 2. Modbus polling method controls data communication. This method is more efficient and stable than the traditional sequential method when the communication is disturbed. Improve the stability and reliability of data reading and writing, and lay a good communication foundation for the whole system. 3. The control module of air compressor is developed by object-oriented programming. The extensibility and generality of the module are improved, and the extensibility and maintainability of the whole system are improved. It is convenient for system upgrade and secondary development. The system can reduce the pressure of gas supply network, save energy and reduce consumption, reduce the working time of air compressor, and balance the working loss of each machine by adjusting the working state of different machines. For the factory equipment maintenance and repair, upgrade to provide convenience. The work of air compressor is controlled by automatic program, which reduces the probability of personnel operation error, improves the real-time and accuracy of control, and is beneficial to the intelligent production management of the factory.
