PAGE 基于多传感器信息判断的火警监控系统软件设计 摘要 为了最大限度的减少由于火灾事故所造成的损失，人们采用了各种措施防止此类事故的发生，其中火警监控系统就是为了减少火灾产生的巨大损失而集成了家用自动报警器和计算机多机串行通信技术于一体的一种集散测控系统。在该系统中，多机通信技术的实现对于系统正常完成实时监控任务具有重要意义。 基于上述原因，本文主要研究了以室内火警监控系统为例的PC机与多台单片机之间的多机串行通信系统的工作原理，通过选择串行通信总线标准、制定数据格式和通信校验方式为此监控系统制定了多机串行通信协议，并且采用VB6.0设计了可视化界面，编写了串行通信软件，接收来自火警监控下位机模拟软件发送的监控信息，并反馈相应应答信息给下位机模拟软件，同时实现了监控信息的实时显示与存储。 本文所设计的程序能对一氧化碳和温度检测系统发送的报警信号进行显示与处理，经过模拟实验验证，程序运行稳定，实现了报警信息的实时传送和显示与存储。该软件经过相应修改既能应用于相关应用场合，具有一定的实用价值。 关键字：VB6.0；MSComm控件；多机串行通信火警监控系统; 多传感器 Abstract In order to minimize due to loss caused by fire accident, people use all sorts of measures to prevent such incidents, including fire monitoring system is to reduce fire produced a loss and integration of the home to be automatic alarm and computer more machine serial communication technology in the integration of a distributed measurement and control system. In this system, computer communication technology for the realization of the complete system normal real-time monitoring task is of important significance. Based on the above reasons, this paper researches on the fire monitoring system for example interior of the PC and many sets of single chip computer serial communication between the working principle of the system, by choosing serial communication standard buses, make data format and communication parity for this monitoring system established computer serial communication protocol, and the visual interface designed through VB6.0, write serial communication software, receive from under fire monitoring a machine simulation software to send monitoring information, and feedback information to a corresponding response under machine simulation software, and realize the monitoring information of real-time display and storage. In this paper the design program to carbon monoxide and temperature testing system of alarm signal sent to display and processing, through simulation experiment, to run the program stability, realizes the alarm information of real-time transmission
