摘要
为了解决用电安全隐患。该系统以电磁感应线圈和变压器的输出电压为检测用电发生漏电、过载、短路和超压故障时的取样电压信号,通过8051单片机控制,运用HD44780字符液晶显示模块和由ISD2650语音芯片,使其具有字符提示和语音提示,在严重故障时又能自动提前跳闸。改变了目前的漏电保护器和过载保护器功能单一,故障出现时没有任何提示等缺点。经大量实验证明单片机多功能用电故障控制器具有性能稳定、安全、可靠是理想的用电保护提示器。
Uses output voltage of the electromagnetic induction coil and transformer as vohage signal of the examination family has the leakage, the overload, the short circuit and presses when the breakdown , through 8051 MCU controlling, utilizes the HD44780 character LCD module and the ISD2650 speech chip, enables it to prompt the character and the voice, when serious failure can automatic advance trip. To change the unitary function of leakage protector and the overload protector, the breakdown appears when shortcomings and so on any prompt, make the family electricity safelier and reliabler.
