The Design And Implementation Of A Monitor System For Small Thermo-Electric Power Machine

This article discusses the design and implementation of small thermo-electricity power machine running monitoring system, especially from its demand analysis, software design and program implementation.This system is a small-middle sized thermo-electricity power machine running monitoring information management system. Its completed configuration includes front unit, front PLC and specific control program, broadband bus network, master control station and data server. This monitoring system accomplishes overall online dynamic management and feedback track of the running status, and gives data reports, fault information, running status curves, etc. for engineer users. This article focuses on discussing the detailed demands of the monitoring task, such as running load monitoring, thermo machine water supply control, temperature control and fuel control. It discusses the above functions’process control modules and main user cases. As for the software design, the article gives main modules’ signal feedback processing and control flows, main programming construction, program units and multi-thread task division, etc. About programming implementation, it discusses this monitoring system’s main programs, and introduces the system’s main tasks and developing technology in programming.This system’s integrated workstation platform runs QNX real-time multi-tasks operating system, and the control front uses Mitsubishi PLC in FXN series as its basic configuration and is developed by C. After test running, it runs basically stable now and reaches its developing targets.
