Research Of Real-Time Measurement & Control Software Technology

Real-Time Measurement and Control (RTMC) system is a kind of common encountered control system in power electrics field with the typical characteristic that each measurement and control task has the real-time feature, which means an upper boundary in both time and space when a measurement and control task runs. RTMC software is the soul of RTMC system, and plays an important role in the design of RTMC system.RTMC system is constructed above the concepts of real-time processing, which include the concepts of real-time system and task schedule, real-time system performance measure, real-time scheduling algorithms, etc. These concepts are the theoretic guide of RTMC software design.The project of ATE RTMC System software development is a typical appliance of RTMC software technology. Real-time and general-utility are two design goals of ATE RTMC System, and the real-time requirements are indicated by data acquiring, data processing, data communicating and etc. After the hardware system designed, the software is usually developed as following steps: selecting the proper real-time software platform and developing method, specifying the software architecture modeling the software, coding and testing.In engineering practice, to solve the problem of real-time processing, the RTMC software designers usually adopt specific software platform to guarantee the real-time performance of underlying processing. Introducing Real-time Operating System (RTOS) is an effective way of building RTMC software platform, which can guarantee the real- time performance of underlying processing as well as prevent higher level software from real-time processing details. Windows is not RTOS, but when real-time extended, Windows can also serve as a candidate of RTMC software platform with considerable real-time performance. ATE RTMC System adopts the solution of Windows + RTX5.1 as its RTMC software platform.
