摘要
城轨新型供电装置具有监控变量多、实时性要求强、控制策略复杂等特殊性,本文设计了与之配套的监控系统。该监控系统的硬件构成为以嵌入式平台为主控制节点,辅控DSP为从节点,工业以太网为主要传输介质,多通道缓冲串口为从节点与供电装置的通讯接口。文章完整地描述了监控系统从节点的软件设计,针对性地提出了周期函数有效值的改进算法,介绍了嵌入式Wince控制平台下人机交互界面的软件设计,并给出了相应的实验结果。实践表明:监控系统具有良好的功能和性能,达到了预期的各项要求。
Because urban rail transit new power supply unit has many monitoring variables and its real-time request is very strict.This article proposed an appropriate monitor system.The hardware of this monitor system contained： the master node（embedded platform）,slave node（DSP）,transmission media（industrial Ethernet） and the communication interface between slave node and power supply unit（MCBSP）.This article described the design of slave node’s software flowchart,designed a new method to calculate the RMS of Periodic function,and mainly introduced the software’s design of the master node based on embedded Wince operating system.At last,the experimental results were shown.According to the practice,this monitor system had fine function and it could reach the expected demand.
