基于PSTN和PLMN的果园泵房智能监控系统

为解决果园泵房偏僻、难以防盗且需人工操作灌溉与喷雾设备的问题,设计了果园泵房智能监控系统。该系统以单片机为核心,结合双音多频远程数据传输技术,实现了电话拨号报警和远程控制两大功能。在选定果园对系统进行实地测试,系统功能成功率为96.5%,报警平均响应时间为4.58 s,远程控制平均响应时间为23.27 s,每次通信成本为通话费用。试验结果表明,该系统能实现其设计功能,满足果园泵房内防盗和远程控制灌溉与喷雾设备的要求。

Intelligent Monitoring System for Orchard Pump House Based on PSTN and PLMN

For finding a way to guard against theft and operate irrigation and spray equipment automatically of remote orchard pump house,an intelligent monitoring system was developed and tested.The system can accomplish two functions,including telephone dialing alarm and remote control with micro controller unit as the core,with dual-tone multi-frequency remote data transmission technology.The system was tested in the given orchard and it proved that the successful rate of accomplishing the functions was 96.5%,the alarm average response time was 4.58 s,the remote controlling average response time was 23.27 s,and every time the cost of communication was the normal telephone fee.Experiments show that the system can accomplish its functions and satisfy the requirements of guarding against theft and remote controlling irrigation and spray equipment of orchard pump house.
