【摘要】：热等静压机的组成较为复杂,包括气体、加热、液压、冷却等系统,设备布局占地面积大,各控制和执行元器件因安装要求较为分散,电器控制系统的可靠性和安全互锁要求是设备关注的重点。基于PLC电器控制系统的设计不仅是打破传统的电器集中控制热等静压机的模式,同时通过优化硬件组态、模块化程序设计、软件模拟仿真、动态视窗控制实现了设备多任务窗口对接、在线监测和故障处理的自动化要求,是解决复杂设备控制可靠性和安全互锁要求的工程化应用的一种手段。本文通过应用PLC控制设备,选择基于目前国际上通用的Profibus DP现场总线的分布式I/O模块,在Step7软件开发平台上进行硬件组态、程序设计,利用其开放式、高灵活性、高可靠性等优势,开发过程控制自动化领域的高端应用,目的是降低复杂设备系统的调试和现场布线难度,缩短设计开发周期,提高故障处理效率,并为多任务系统提供灵活机动的扩展方案。热等静压设备的加热系统和温度控制系统是电器控制系统的重要组成部分,本文分析介绍了热等静压设备的加热系统和温度控制系统的组成。PID控制作为最常用的控制手段,本文分析了其优点与不足,并对PID控制参数的整定方法进行了研究。WinCC(Windows Control Center,窗口控制中心)是西门子公司(Siemens)实现PLC与上位机之间的通讯及上位机监控画面的制作的组态软件。主要介绍如何利用WinCC建立监控画面,使监控画面根据现场实际情况动态显示。以热等静压设备的控制系统为例,介绍了使用WinCC系统的硬件配置,组态监控系统,创建动态人机界面,实现过程监控的具体步骤。本文结合公司多年的热等静压机电器控制系统的设计经验,对设计对象进行现场技术调研,摸底设备存在的可靠性和安全性问题,通过需求分析、系统设计,对进口热等静压设备的电器控制系统进行全面升级改造。经过现场性能、功能检测,设备电器控制系统自动化升级改造满足用户协议要求,为公司热等静压机设计规范提供了坚实的理论基础和工程应用支撑。
[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.
