摘要
文章研究一种基于单总线的智能楼宇监测系统,实现对多点环境温度、湿度和火灾烟雾的实时监测。温度测量选用单总线智能温度传感器DS18B20,直接输出被测点温度的数字量;湿度和烟雾量的测量则通过湿度传感器HIH-3610和反射式光电感烟探测器输出模拟信号,经串行A/D转换器就地进行模数转换,再通过单总线接口按照1-Wire通信协议与温度传感器连到同一根串行通信总线上;检测信号的获取由单片机控制,单片机系统通过RS-232/485接口与PC主控制器相连,PC机上运行基于LabVIEW平台开发的后台监控软件,通过可视化模块实现监控场所的虚拟再现以及远程监测。
The monitoring system of intelligent buildings based on 1-Wire bus can realize the real-time monito- ring of the multi-point temperature, humidity and fire smoke. In temperature measurement, the intelligent temperature sensors DS18B20 are adopted, which can directly produce the figures of measured temperature. The measurement of humidity and smoke is through the humidity sensors HIH-3610 and photoelectric smoke detectors to output analog signals, and in situ analog-digital conversion is realized by the serial ADC DS2450. Then they connect to the 1-Wire with temperature sensors together through the 1-Wire interface in accordance with the 1-Wire communication agreement. The signal detections of access is controlled by the MCU. The MCU system connects to the PC through RS-232/485 interface. The monitoring software based on LabVIEW runs on the PC, thus achieving a virtual monitoring environment reproduction and remote monitoring through visualization module.
