摘要
针对红外组件可靠性试验环境的自动控制及失效保护要求,设计了一种自动化试验环境监控系统。系统采用可编程逻辑控制器(PLC)为控制核心,通过Profibus-DP总线通信对整个监控系统进行高速集中控制,实时监测现场设备状态,协调控制现场设备按序运行,实现试验真空的自动维持以及在真空失效时的报警保护。同时基于Wincc flexible软件设计了触摸屏人机操作界面,对设备运行数据的实时显示及存储。最后对该监控系统进行了实验验证,实验结果表明,该系统运行稳定可靠,自动维持的真空度优于10-4 Pa,自动维持的温度低于90 K,可满足红外组件寿命试验的要求。
Abstract
To deal with the requirements of automatic control and failure protection during the reliable test of IR component, a system to monitor the testing was proposed. Programmable logic controller (PLC) was used as the control center. By use of the profibus-DP bus as the communication bus, the field device was monitored in real time and coordinated to operate in sequence. And then the testing environment was automatically maintained. The failure protection would automatically run when the testing environment failures. Meanwhile, based on Wincc flexible, the operational status of equipment was displayed and stored the operational status of equipment in real-time with the human-machine interface. Finally, a reliable experiment was performed by use of the monitoring system, and the results show that the monitoring system can run stably. By use of which the auto maintaining vacuum is superior to 10-4 Pa, and the auto maintaining temperature is lower than 90 K, which can satisfy the requirements of the reliable test of IR component.
