A 'black box' structure without any indicator lights or keys can be adopted, so the alarm arranged on a concealment separated from the telephone can not be destroyed and thus raise safety.
Description
The utility model belongs to a kind of device that utilizes telephone wire to report to the police automatically.
The telephone automatic alarm device is to call for help or during other alert in breaking out of fire, illegal invasion, acute disease, in time by the device of telephone wire to parties concerned's warning, how existing this class device is provided with a plurality of display elements and buttons on alarm, instruct the carrying out that pre-sets, cancels setting or other operation of alarm signal by the current state of display alarm.So alarm will be put together with phone, disguise and confidentiality are bad, easily destroyed.
The utility model aims to provide a kind of good concealment, and is simple in structure, the call voice autoalarm of easy operating.
The technical scheme that realizes above-mentioned purpose is (referring to Fig. 1), the utility model is provided with housing, be provided with in the housing and can coordinate each element circuit work, but and have an one-chip computer module (1) that data memory is preserved in power down, can send the probe of alarm signal, has speech recording and reproducing function, the warning message treatment circuit (2) of recording substance is not lost in power down, can decipher signaling circuit (4) frequently to the phone double-tone of decoding of phone double-audio signal and signaling, automatic switching circuit (6), and have the artificial handoff functionality of simulation, can transmit telephone keypad, audio alert, the telephone line repeat circuit (5) of audio signals such as audio coding; The output of described alarm probe connects single-chip microcomputer (1) input, alarm voice message circuit (2) control end and single-chip microcomputer join, be connected with the transmission of telephone line repeat circuit (5) two-way signaling simultaneously, telephone line repeat circuit (5) is deciphered signaling circuit (4) frequently by double-tone and is connected with the transmission of single-chip microcomputer two-way signaling, the audio output of outside line and subscriber phone links to each other with telephone line repeat circuit (5) by being subjected to monolithic processor controlled automatic switching circuit (6), and being provided with in the telephone line repeat circuit can the transmitted in both directions audio signal, and the audio frequency transformer that telephone network and this device power-supply system are isolated; It is characterized in that:
This device also is provided with typing and is solidified with the operation voice warning circuit (6) that content is not lost in human-computer dialogue voice signal, power down, and its control end links to each other with single-chip microcomputer, solidifies the voice signal output and links to each other with telephone line repeat circuit (5).
Operation principle of the present utility model is: in advance various fixedly suggestion voice signals by certain procedure operation are solidified to be stored in and operate voice warning circuit (3) lining, the user opens alarm and picks up a receiver, single-chip microcomputer is that the follow procedure tissue is finished each operation indicating voice signal, and be transferred in the telephone receiver by telephone line repeat circuit (5), operate with interactive mode guides user, the user can be under voice suggestion, required alarm call number etc. is imported with telephone keypad, pass to double-tone through the telephone wire repeat circuit and decipher signaling circuit (4) frequently, but the power down of storing one-chip computer module after the decoding is preserved in the data memory, more corresponding warning message is imported and is recorded to by monolithic processor controlled warning message treatment circuit (2) lining by microphone and telephone wire repeat circuit simultaneously.Generally, automatic switching circuit is in off state by Single-chip Controlling, and telephone wire repeat circuit and outside line are disconnected, and the telephone set that is connected on the outside line uses as usual.When probe sends alarm signal, single-chip microcomputer starts automatic switching circuit on the one hand this device telephone line repeat circuit and outside line is connected, and make the simulation of telephone line repeat circuit be (low resistance) phone off hook state, but single-chip microcomputer will exist power down to preserve corresponding alarm call in the data memory or PB plane No. sign indicating number to be passed to double-tone and to decipher frequently in the signaling circuit on the other hand, decoding back simulation keyboard dialing sends on the outside line by the telephone line repeat circuit that is in the simulation off hook state, the outside line of single-chip microcomputer identification simultaneously is to be in that the line is busy, busy tone, or on-state, the line is busy as if being in, the busy tone state, single-chip microcomputer makes telephone line repeat circuit and outside line shutoff be in the simulation hook state again by automatic switching circuit, and then send signal, open the telephone line repeat circuit and be in the simulation off hook state, continue the simulation dialing, be in on-state until recognizing outside line, at this moment promptly start the message treatment circuit of reporting to the police sends corresponding warning message signal or PB machine to outside line by the telephone line repeat circuit information code.
Because this device is provided with the operation voice warning circuit, available interactive mode is carried out various operations, not only made things convenient for the user, the more important thing is indicator light and button that various prompting operation programs needn't be set on warning device, that is to say that the user only needs can carry out various operations by follow procedure by telephone receiver and keyboard, make alarm can adopt " black box " structure of no any indicator light and button, so just can place it in the shelter of separating with telephone set, be not subject to destruction, improved fail safe.
