Abstract

The utility model relates to an intercom house guard mainly comprising a main machine. The interior of the main machine is provided with a circuit composed of a microprocessor, a voice memory and a ringing unit. The circuit is respectively connected with outdoor and indoor intercoms and a home telephone. An input terminal of the circuit is connected with a telephone office line. In normal state, the telephone can be used for intercommunicating with the intercoms. Moreover, when a user goes out, a plurality of telephone numbers can be arranged in the circuit, when a visitor press a belling button, the circuit automatically dials the user for talking to the visitor. In addition, when someone illegally enters the room, the utility model can automatically start an alarm and automatic dials a safety guard unit which is arranged in the circuit for notification. Therefore, the home guarding purpose is achieved.

Description

Intercom is protector at home

Main purpose of the present utility model provides a kind of intercom protector at home, it is provided with a main frame, make main frame be connected in chamber, inside and outside intercom and telephone set, and phone exchange line, and can be by the multiple groups of phone numbers that prestores in the set circuit in the main frame, when owner goes out and when having the visitor to ring the doorbell, main frame can dial automatically to the user, for the user with at one's side phone and the intercommunication of outdoor intercom formation.

Another purpose of the present utility model provides a kind of intercom protector at home, the main frame of this device can be connected in a siren, when only leaving old man or child among the manager and causing danger situation, can press intercom at any time to start siren, and transfer to preset number to inform user or relevant unit automatically, constitute the effect of protection at home.

Another purpose of the present utility model provides a kind of intercom protector at home, this main frame can be located at the door, window detecting element with the remote control mode intercommunication, when the user goes out and when having the people to invade, can start siren and automatically dialing give security unit, reach the purpose of home safety.

The utility model is achieved in that and mainly is provided with a main frame, inserted electronic circuit at this main frame, make this main frame be connected to an intercom, an outdoor intercom, a telephone set and phone exchange line, wherein, the electronic circuit of this main frame includes a microprocessing unit, make this microprocessing unit be connected in this indoor and outdoor intercom and telephone set,, constitute the intercommunication of indoor and outdoor intercom and telephone set by the processing of this microprocessing unit; The electronic circuit of this main frame includes another microprocessing unit that is connected in voice unit, memory again, for setting multiple groups of phone numbers and pre-recording the emergency voice, when the user goes out, can be by the automatic dialing of this microprocessor, constitute the user by the visitor intercommunication of distant place with outdoor intercom, or when urgent, press intercom, and dial into relevant unit automatically with voice help-asking, reach the purpose of protection at home.

The microprocessing unit of this main frame electronic circuit is connected with a siren, urgent or when having the people to invade, and can be by this siren of pushbutton enable of intercom, to constitute the purpose of caution, emergency.

The electronic circuit of this main frame can constitute the intercommunication of remote control with the monitoring element that is installed on door, window, when having the people to invade, can obtain the signal of monitoring element by main frame, to start siren or dialing emergency automatically.

Following conjunction with figs. and embodiment describe structure of the present utility model, characteristics and effect thereof in detail.
