Central Heating On-site Monitoring Of Computer Systems Research And Design

The local central heating is become one of the necessary steps for city modernization in the north of china , it is more and more important that how to manage and control the heating net with scientific method as the heating net expands gradually.The Distributed Control System of Central Heating (DCSCH) solves the problem of heating net management and control with better effects.This paper is on the basis of the computer measurement and control system on heating net in Shenyang Huanggu heating-power plant <> The sub-station' s hardware and software of DCSCH is studied and designed by writer,, And the hardware is composed with power, A/D, D/A, DI, DO and display circuit which used by Single-chip computer of 89C52 while the software includes four parts: communication, data collect, display of LCD and control <, Using the serial port of Single-chip computer to communicate with upper-computer while communicate with LCM by adopting the bus to simulate serial port, some measurers of resisting interfere are adopted in hardware and software in order to composed a effective spot monitor computer system ?...
