[Abstract]:The composition of the hot isostatic press is more complicated, including gas, heating, hydraulic, cooling and other systems. The layout of the equipment covers a large area, and the control and execution components are scattered because of the installation requirements. The reliability and safety interlocking requirements of electrical control system are the focus of attention. The design of electrical apparatus control system based on PLC is not only to break the traditional mode of centralized electric apparatus control hot isostatic press, but also to optimize hardware configuration, modularize program design and software simulation. Dynamic window control realizes the automation requirements of multi-task window docking, on-line monitoring and fault processing. It is a means of engineering application to solve the requirements of complex equipment control reliability and security interlocking. In this paper, the distributed I / O module based on the international Profibus DP fieldbus is selected by using the PLC control equipment, and the hardware configuration and program design are carried out on the Step7 software development platform, making use of its open architecture and high flexibility. With the advantages of high reliability and so on, the purpose of developing high-end applications in the field of process control automation is to reduce the difficulty of debugging and field wiring of complex equipment systems, shorten the design and development cycle, and improve the efficiency of fault handling. It also provides flexible and flexible expansion scheme for multitask system. The heating system and temperature control system of hot isostatic pressure equipment are important parts of electrical control system. The composition of heating system and temperature control system of hot isostatic pressure equipment is analyzed and introduced in this paper. PID control is the most commonly used control method. In this paper, the advantages and disadvantages are analyzed, and the tuning method of PID control parameters is studied by. WinCC (Windows Control Center,. Windows Control Center is the configuration software of Siemens (Siemens) to realize the communication between PLC and PC and to make the monitor picture of PC. This paper mainly introduces how to make use of WinCC to set up the monitor picture, so that the monitor picture can be dynamically displayed according to the actual situation on the spot. Taking the control system of hot isostatic pressure equipment as an example, this paper introduces the concrete steps of using WinCC system to configure the hardware, configure the monitoring system, create the dynamic man-machine interface and realize the process monitoring. In this paper, based on many years of experience in the design of electrical control system of hot isostatic press, the design object is investigated on the spot, the reliability and safety problems of the equipment are found out, and the system is designed through demand analysis. The electrical control system of imported hot isostatic pressure equipment is upgraded. Through field performance, function testing, automatic upgrading and upgrading of equipment and electrical control system to meet the requirements of user protocols, it provides a solid theoretical basis and engineering application support for the design specification of hot isostatic press in our company.
