本监测系统利用无线射频与GPRS网络相结合的方式,监测终端将温度传感器与烟雾浓度传感器采集到的数据通过无线射频发送到基站,再通过基站的GPRS网络将数据发送到监控中心,来实现对林火的实时监测。通过监控中心对整个网络的控制,可以实时监测森林的状况。本监测系统结合无线射频和GPRS网络的优势,无线射频使监测终端更加方便安装,GPRS网络可以实现远程监控管理。本监测系统可以通过短信、服务器、定时和报警触发方式启动,可以实时采集现场数据。本设计的硬件电路以LPC767芯片为核心,采用RF200无线射频芯片和MC55模块进行了各种外围电路设计,采取了低功耗与抗干扰措施。制作出了电路板,并且完成了部分功能的测试。
The monitoring system uses a combination of radio frequency and GPRS networks to monitor the terminal temperature sensor and smoke concentration sensor to collect data collected by wireless radio frequency to the base station, and then through the base station’s GPRS network to send data to the monitoring center to achieve the Forest fire real-time monitoring. By monitoring the entire network control center, you can monitor the status of the forest in real time. The monitoring system combines the advantages of radio frequency and GPRS networks, radio frequency to make monitoring terminals more convenient to install, GPRS network can achieve remote monitoring and management. The monitoring system can start by SMS, server, timing and alarm triggering, real-time acquisition of field data. The design of the hardware circuit to LPC767 chip as the core, using RF200 RF chip and MC55 module for a variety of peripheral circuits designed to take low-power and anti-jamming measures. Produced a circuit board, and completed some of the functions of the test.
