摘要
针对电缆被偷盗的严重情况,设计了一套基于无线网络的电缆防盗报警系统。根据巴特沃斯快速设计方法,进行高通滤波器参数计算及仿真分析,使用对脉冲计数方式,完成了监控电路软硬件设计,与上位机相连运行模块测试软件,完成了控制系统的设计。该报警系统可以监测管理区域内电缆线路的运行情况,当电缆出现断路时,系统将及时把被盗窃电缆的信息传给监控中心,同时通过GSM(global system for mobile communications)无线网络把该信息以短信息形式转发到管理人员的手机。
According to the serious situation that cable is often stolen, a cable anti- theft alarm system is designed based on wireless network. The high - pass filter parameter is calculated and simulated. The monitoring circuit and software and hardware of control system is completed. The system can monitor cable line situation in the management area. When the cable is turning off, the system will promptly send cablestolen message to the monitoring center, and at the same time, the information in the form of short message is sent to manager＇s phone through GSM （global system for mobile communications）.
