Abstract

The utility model provides a calling alarm device, which is composed of a microprocessor, a display circuit, a keyboard input circuit, a storage circuit, a snubber circuit, an alarm circuit, a diode coding circuit connected with the microprocessor. The paging communication and alarm display are independent devices and can be combined into one. When one user encounters the dangerous case, the room number which generates the dangerous case can be quickly and precisely displayed via a host machine box. The host machine simultaneously sends out the signals of indicating lamps to each extension for alarming the dangerous case. The utility model provides an integral and practical device for the communication of the tall building, theft protection, alarm, and indication.

Description

Calling alarm device

The utility model relates to a kind of building apartment warning device, especially a kind of call alarm device that is applicable to the many minutes families of building of skyscraper.

At present, existing various call burglar alarms, their major parts are to notify from a phone call, report to the police and separately use, notify from a phone call and just be used to communicate with each other, warning system also just is used for single warning, and automaticity is low, branch family terminal band less, the user uses inconvenience.

The purpose of this utility model provides notifies from a phone call communication and is the call alarm device of one with reporting to the police a kind of can the collection.

Technical solution of the present utility model is: be connected to display circuit 2, keyboard input circuit 3, storage circuit 4, buffer circuit 5 and warning circuit 6 with microprocessor 1, display circuit 2 joins with keyboard input circuit 3, is connected to diode coding circuit 7 with buffer circuit 5.

Also be connected to timing circuit 8 and sensing circuit 9 with buffer circuit 5.

Be connected to flasher circuit 10 with microprocessor.

The utility model is compared with prior art, is that employing is the call alarm display alarm of control core with the one-chip computer, notifies from a phone call communication and alarm indication, can be autonomous device, also can unite two into one.When certain branch family runs into dangerous situation, can on host box, demonstrate the room number that dangerous situation takes place quickly and accurately, and send the pilot lamp signal to all each extension sets, so that remind full building to notice that this building has dangerous situation to take place at the synchronization main frame.Room number on the display provides the open-and-shut site of an accident for the relevant personnel handle dangerous situation rapidly, is modern high-rise building communication, antitheft, the comprehensive utility unit of reporting to the police, showing.

Fig. 1 is the circuit block diagram of the utility model embodiment.
