具有远程报警的用电保护器设计

Remote Alarm Electricity Protector Design

为了提高用电安全性和可靠性,减小用电事故发生。通过过压、过流、欠压、漏电和短路等,划分为安全、轻度故障和重大故障3个级别控制。由用电故障线圈采集数据,单片机根据安全用电故障级别系数Wi来确定故障的级别,输出提示、切断电源和报警信号。同时通过GR47无线模块和GPRS网络对相关人员进行用电故障远程报警,为避免重大用电故障发生抢得保贵时间,从而实现了用电故障远程监控的目的。实验表明,该智能化用电故障远程监控系统用于民房、学生宿舍、工厂和商场等用电场所,都具有良好的可靠性、实用性和安全性等优点。

To improve the safety and reduce the power failure, by rneans of over voltage, over current, leakage and short circuit monitor, the power status can be classified as safe, slight failure and major failure 3 levels of control. Data collected by electricity obstacle pickup coil, SCM determines the power failure level by the level coefficient Wi, and signals warning, cuts off power or alarms. Meanwhile, through GR47 wireless module and GPRS network sends out messages to avoid serious losses and save time for maintaining. The intelligent power failure remote monitoring system can be use in families, student dormitories, factories and stores.
