Development of a Measurement and Control System Based on TCP/IP Protocol

摘要:

产品进行湿热等环境试验的主要成本为人工费和试验设备使用费，降低批量产品环境试验成本的有效方法为提高试验效率，缩短试验总时长。多通道测控系统可实现多台产品同时测试，不仅可以简化单台产品测试流程，还可成倍缩短批量产品试验的总时长。基于1553B协议的多通道测控系统主要用于控制器单机产品的验收试验。集供电、通信与信号调理功能于一体的测控箱，实现了工控机与被测产品的电连接，采用分时复用技术实现多台被测产品同时试验，异步测量，成倍降低试验成本；以 VisualStudio为开发环境，采用C#语言，在工控机内设计开发一套测控软件，可实现智能通信、信号采集、数据分析与处理，试验结果清晰直观，大大简化了试验人员数据分析的繁琐。

Abstract:

The cost of hot and humid environment test is mainly the labor cost and equipment occupancy fee. The effective method to reduce the cost of mass product environment test is to improve the test efficiency and shorten the total time of the test. The multi channel measurement and control system can be used to test multiple products simultaneously. It can not only simplify the single product testing process, but also shorten the total time of the test. The multichannel measurement and control system based on 1553B protocol is mainly used in the acceptance test of the controller. A measuring and controlling box which integrates power supply, communication and signal conditioning functions in one, realizes the electrical connection between the industrial control machine and the measured product. The time division multiplexing technology is used to realize the simultaneous test of several measured products, asynchronous measurement, and double reduce the cost of the test. VisualStudio is used as the development environment and the C# language is used to design program in the industrial control machine. The set of measurement and control software can realize intelligent communication, signal acquisition, data analysis and processing. The test results are clear and intuitive, which greatly simplifies the tedious analysis of the data of the experimenter.
