基于嵌入式实时内核的远程测控终端的研究
|
摘要
基于嵌入式实时内核的远程测控终端是以铁路供水系统为背景的、根据嵌入式系统设计原理构建的现场控制系统。
本文提出了远程测控终端设计方案,对远程测控终端各部分的功能做了描述。详细介绍了远程测控终端的CPU—W77E58单片机和键盘显示、数据采集、开关量输出、串行接口等外围电路。通过对实时内核μC/OS-II源代码的分析和研究,结合该系统使用的CPU提出了具体的移植方案。在此基础上,详细讨论了远程测控终端的外部输入/输出设备驱动程序的编写以及在μC/OS-II实时内核下的实现方法。
本文还分析了远程测控终端远程通信方式,利用RS485/以太网转换器实现远程测控终端与监控中心的通信功能。
该远程测控终端不仅可以用于铁路供水系统,还可以应用于电力、水利、石油、化工、市政等行业中,用于地理环境恶劣、无人值守的环境下进行远程监控,具有普遍的意义和实用价值。
The remote measuring and controlling terminal based on embedded real-time operating system (RTOS) discussed in this paper is a field control terminal system with the background of the railroad supply water system, and according to the embedded system design principle.
In this paper the design scheme of the remote measuring and controlling terminal is presented, and its functions of all parts are described in detail, which uses Winbond’s W77E58 as its MCU. The peripheral circuits of the terminal—display, keyboard, data collection, switch output, serial interface, are introduced. The real-time kernel ofμC/OS-II, which is a kind of real-time operating system, is introduced. Through analysis and research of source codes ofμC/OS-II, the kernel is known well. And the transplant plan is given based on W77E58 MCU. On these bases, the I/O devices are discussed in detail. To every device, we discuss their realization based onμC/OS-II.
Additionally, the communication method of the remote measuring and controlling terminal is introduced in this paper. Making use of the RS485/ Ethernet converter, the terminal realizes long-range measure and control communication function.
It may be applied not only in the railroad supply water system, but also in the electric power, water conservancy, petroleum, chemical engineering, etc. It is used in the bad geography environment and unmanned guard remote control system. It has widespread application and practical value.
