无线环境监测模拟装置
摘要
1B1B1B1B1B1B1B1本论文设计的是一个以STC89C52单片机为主控芯片的无线环境监测模拟装置系统,主要由监测终端和监测节点组成。结合温度传感器DS18B20、光敏电阻以及空气质量传感器MQ-135等来实现对周围环境温度、光照情况和大气质量等数据的收集,采用无线通信技术,传送给监测终端的主机接收,同时通过LCD12864显示当前环境情况,实现对环境的监测。系统的节点主要由三部分构成:数据采集、数据处理、无线收发模块;在监测终端上由无线收发模块和数据处理两部分构成。该无线环境监测模拟装置利用无线收发技术,通信协议采用点名校对的方式,电路结构简单,系统性能稳定可靠,功耗较低。

Wireless Environmental Monitoring Analog Devices
Abstract
2B2B2B2B2B2B2B2This paper designed a STC89C52 MCU for master chip ireless environmental monitoring simulator system, mainly by monitoring terminals, and monitoring node. Combination of the temperature sensor DS18B20, photo resistor, as well as air quality sensors MQ-135 to ambient temperature, light conditions and air quality data collection, wireless communications technology, sent to the host of the monitoring terminal to receive, display the current environment through LCD12864 to achieve environmental monitoring. Node of the system consists of three parts: data acquisition, data processing, wireless transceiver modules; two parts by the wireless transceiver modules, and data processing in the monitoring terminal. The wireless environmental monitoring analog devices use wireless transceiver technology, communication protocol named the circuit structure is simple, stable and reliable system performance, lower power consumption.
