摘要
针对Linux操作系统下自动考核测试系统的需求进行系统设计,提出了整体测试方案和外部仪表设备的测控方案。利用Python语言实现基于VISA的仪表测控、自动流程控制、Modbus通讯和多线程等功能,创新地采用Web服务器的方式提供测试系统操作界面,并给出了设计思路和实现方法。测试结果表明,系统满足自动测试系统的要求,在提高效率的同时还避免了操作人员在有害实验环境下的长期工作。
A system is designed according to the requirement of automatic examination test system for Linux operating system, and the overall test plan and the measurement and control scheme of external instrument are proposed. VISA based instrumentation measurement and control, automatic process control, Modbus communication, multi-threading and other functions are achieved by using Python language. The test system operating interface is provided innovatively by using Web server. The design idea and implementation method are given.The test results show that the system can meet the requirements of automatic test system, and it can improve the efficiency and avoid the long term operation of operators in the harmful experiment environment.
