摘要:

为了提高森林火灾监测站的太阳能电源的监测管理水平,采用GPRS无线通信技术设计了分布式火灾监测站的太阳能电源监测管理系统,系统由数据中心管理服务器、监测站、太阳能电池板电源监测单元和传输网络组成；通过精密电阻分压的方法,利用单片机MSP430F149的ADC口测量太阳能电池板的输出和蓄电池的电压,并记录和运算蓄电池的放电电流和内阻,通过GPRS无线模块建立与数据中心服务器的TCP/IP网络连接,将采集到的火情和电源工作状态上传；数据中心服务器主要负责接收、处理、分析统计和显示来自各监测站的数据,并存入数据库ACCESS2003中；经过实验表明,该系统工作稳定可靠,实现了对森林火灾监测站点电源供电状态的集中管理,避免了由于电力故障造成火灾监测盲点的出现。

Abstract:

In order to improve the solar power management of fire monitoring stations in forest, the solar power monitoring and management system of distributed fire stations were designed using the GPRS wireless communication technology, the system was composed of data center management server, monitoring stations, solar panel power monitoring unit and the networks. Through a precision resistor divider method, the MSP430F149 microcontroller ADC port was used to measure the voltage of solar panel and battery, and the battery discharging current and the internal resistance of the battery were record and calculated, which were sent to the data centre server with the fire and power status through the TCP/IP network connection using GPRS wireless module. The data center server is mainly responsible for receiving, processing, analysis and display of data from various stations, and stores them in the database ACCESS2003. Experimental results show that the system is stable and reliable, achieving the power supply state centralized management for forest fire monitoring stations to avoid the fire monitoring blind spots due to power failure.
