基于GPRS的荔枝园防盗远程监测系统

A Remote Alarm System Against Theft for Litchi Orchard Based on GPRS

针对种植规模大的荔枝园劳动力短缺以致安保管理困难的问题,提出了一种基于GPRS网络的防盗远程监测系统。该系统由单片机控制模块、GPRS通信模块、传感器模块、显示模块、报警模块及远程数据中心6部分组成,借助GPRS数据业务,实时地将荔枝园现场的防盗信息发送至远程数据中心,实现对异常情况的报警。测试结果表明:系统的平均数据传输时间为29.91s,6种传感器相邻安装模式中能正常报警的模式有两种。一种模式是传感器间距为3cm且夹角为30°,人到传感器距离为40cm;另一种模式是传感器间距为6cm且夹角为3 0°,人到传感器距离为7 0 cm。该系统安全性高,使用灵活,相比传统的监控系统更有优势。

Aiming at the security management difficulties in large-scale litchi orchards with labors shortage , a remote an-ti-theft alarm system based GPRS was proposed in this paper .The system was composed of single chip microcomputer module ,GPRS communication module , sensor module , display module and alarm module .The human body infrared in-duction probe was adopted to monitor orchard information in real time .The GPRS communication module was used to send abnormal location information to the users ’ mobile phones .Results showed that average data transmission time was 29 .19 s.Two modes could normally alarm in adjacent installation mode of six sensors .One mode was that the sensor spacing was 3 cm with 30 ＆#176;sensor angle and 40 cm-distance between the people to the sensor .Another mode was that the sensor spac-ing was 6 cm with 30 ＆#176;sensor angle and 70 cm-distance between the people to the sensor .This system was safe and agile , and it has more advantages over traditional monitoring systems .
