CN2786726Y - Electric leakage protector remote control receiver - Google Patents

Abstract

The utility model relates to a long distance remote control receiver with a leakage protector, which is composed of a double audio integrated circuit and a single chip computer chip processor circuit. The single chip computer chip processor circuit respectively controls a relay driving circuit, an information storing circuit and a photoelectric coupler so that a long distance remote control circuit can be switched on and off, so as to obtain the purpose of relieving operators'work intensity.

Description

Earth leakage protective device Remote receptacle

Technical field: the utility model relates to a kind of remote-controlled receiver, particularly relates to a kind of earth leakage protective device Remote receptacle that has.

Technical background: in vast rural area and outlying mountain area, the conveying connecting and disconnecting of electric power all need the electrician in rural area to make little runs to and fro, like this, wasted manpower on the one hand, on the other hand, also waste the time, also line fault can occur sometimes, need to detect and maintenance, so will cause the waste on the more man power and material.The purpose of this utility model will provide a kind of earth leakage protective device Remote receptacle exactly, and it can overcome the defective of above existence, accomplishes detection, the integrated control of remote control.

Summary of the invention: the purpose of this utility model is to realize like this; earth leakage protective device Remote receptacle; formed by double-tone frequency integrated circuit and singlechip chip processor circuit; it is characterized in that: described singlechip chip processor circuit is pilot relay driver IC, storage circuit and two photoelectrical couplers respectively.The utility model line design is reasonable, manipulates safety, convenient, and can realize remote-controlled operation, can report to the police automatically to the electric leakage circuit.

Description of drawings: Fig. 1 is line design figure of the present utility model

U1, double-tone integrated package U2, singlechip chip processor U3, relay driver integrated package U4 reservoir U7, photoelectrical coupler U8, photoelectrical coupler frequently in the drawings

Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing

In the drawings; earth leakage protective device Remote receptacle is made up of U1 double-tone frequency ic circuit and U2 singlechip chip processor circuit; it is characterized in that: described U2 singlechip chip processor circuit is controlled U3 relay driver integrated circuit respectively, U4 reservoir circuit and U7, two photoelectrical couplers of U8.During concrete enforcement, when incoming call, ringing level makes the conducting of U6 optocoupler by telephone socket J1 through R12, C12, and the output low level signal is delivered to 34 pin of U2 single-chip microcomputer, when ringing number is to set ringing number when identical by single-chip microcomputer, 32 pin level step-downs make Q2, Q3 conducting, the K9 adhesive, connect simulation off-hook resistance R *, R* determines by the voltage of telephone wire, and that guarantees to converse is stable, hears the prompt tone that 33 pin amplify through Q1 then.Next the operator just can input the password that " * " word is taken the lead, deliver to U1 by the double-audio signal that telephone wire sends, double-tone is 1,2 pin of integrated package frequently, amplify through inside, and decoding converts digital signal to, deliver to 36,37,38,39 pin of U2 singlechip chip processor, read in digital signal and carry out analyzing and processing, and with the value of former setting relatively, as identical, then send correct prompt tone, then send wrong sound as inequality.When hearing correct sound, just can to earth leakage protective device stop sending to row control, button " * " is opened in input, the numbering of input earth leakage protective device is carried out first protector as " * 1 " for the K1 adhesive and is given.The power failure button is set to the beginning of " # " word, disconnects for K8 as " #8 ", and promptly the 8th transmission line of electricity has a power failure.If do not know the power failure of current circuit and send electric situation and circuit whether leak current fault is arranged, during design, by the query key of " 9 " word beginning, as " 92 " is the ruuning situation of the 2nd circuit, hear " ticking " one for sending electricity, two for having a power failure, and for circuit fault arranged three." S1-S8 " is panel box, and input low level, delivers to 21 pin, hear 33 pin send the prompt tone that amplifies through R13, Q1, G3 three for this reason circuit fault is arranged.U3 relay driver integrated package can drive 8 relays simultaneously.U4 is a block storage, is writing down transmission or not situation and leak current fault situation and various parameter, and data are not lost when guaranteeing grid power blackout.S9 is the soft-touch type reset button, when the operator forgets the tinkle of bells, in the time of can not operating, is pressed into reset button during outage and does not discharge, and energized can be recovered the original start state again.

Claims (1)
