摘要
目前火灾报警系统逐步向智能化、网络化方向发展。文中介绍了一种多点测量火灾报警系统。以数字温度传感器为探测器,以AT89C51为数据处理核心,并连接PC机作为上位监控系统。文中对数字温度传感器中便笺式存储器读取的9字节数据进行了详细说明,对温度数据格式与数据处理进行了描述。阐述了在程序设计时实现温度测量需要完成的步骤。给出了可组网的火灾报警系统连接图和在液晶显示器上的温度数据显示。火灾报警系统有良好的扩展性而且组网方便。
Fire alarm system is gradually developing with the network and intelligence. Introduced a fire alarm system with many point measurement. The digital temperature sensor is a detector. Single-chip microcomputex AT89C51 is the core of data processing. PC is the monitoring and control system as the upper level. 9 bytes data that is read from scratchpad memory of temperature sensor was illustrated in details. The data format and data processing of temperature were described. In order to realize the temperature measurement, the program procedure was expounded. Fire alarm system connection figure and temperature display on the LCD were given out. The fire alarm system has good expansibility and network is easily constructed.
