Each functional circuit is respectively connected with the central control circuit, thereby, human control or automatic alarm is done toward systems such as police, fire-fighting, etc. by the existing communication line, and after the police receives the alarm, each positive remote prevention action is directly adopted to the alarm spot as well as by the common communication network, which saves time for all kinds of rescues.
Description
The utility model relates to a kind of alarm, particularly relates to a kind of intelligent alarm.
Existing alarm generally can only be reported to the police merely, and alerted parties can't directly be taked any active measures to the scene of reporting to the police, and often affects adversely opportunity, causes damage.
The purpose of this utility model is: providing a kind of can accurately report to the police rapidly, can directly take the intelligent alarm of various effective long-range strick precaution restriction measures to the scene of reporting to the police by the information of alerted parties by providing in the phone of receiving a crime report again.
Further purpose of the present utility model is: a kind of intelligent alarm with self-protection function is provided.It can send alerting signal automatically when circuit abnormal.
Task of the present utility model is finished like this: form intelligent alarm by touch-tone telephone and alarm control unit, be provided with the central control circuit that constitutes by micro computer CPU8031, storer EPROM2732 and combinational logic circuit in the alarm control unit, and be aided with three groups of functional circuits, each functional circuit is connected with the I/O device 8255 able to programme that is added in the 8031P1 mouth respectively:
A. alarm communication system signal processing circuit, comprise signal transceiver DTMF8800, multiple signals switch and by 4N25, the ring detecting circuit that LM358 forms, the alarm communication system signal processing circuit is connected with the I/O device 8255 able to programme that is added in the 8031P1 mouth, another input port links to each other with input buffer, and the input end of input buffer is provided with warning device;
B. recording and playing circuit is made up of sound circuit ISD1400 series, post pole body, little acoustic pickup and apportion device;
C. long-range anti-norm signal receiving processing circuit comprises driving circuit and on-off circuit that the interface circuit, C4066 and the MC1413 that are made up of 5551,5401 chips form, and four～16 code translator 74HC154; Under the control of CPU8031, the various alarm call numbers of employing telephone key input, subscriber-coded, and establish/withdraw a garrison password etc., all deposited in EPROM2732.The information that the alerted parties of prerecording must be understood directly is stored in the sound circuit.When abnormal conditions took place at the scene, the litigant was as long as start warning device, and alarm will be by signal transceiver DTMF8800 in the time of setting, and each alarm call to storage sends audio alert according to the order of sequence.After alerted parties is received alarm, can directly send long-range strick precaution order by the button on the phone of receiving a crime report, long-range strick precaution order is via signal transceiver DTMF8800, interface circuit, be converted into data-signal, carrying out long-range strick precaution by four～16 code translator 74HC154 again handles, to the various positive restriction measures of field conduct, press logical high electricity, open and take the photograph, video tape recorder, startup electromagnetic door automatic blocking, start Automatic Fire Extinguisher injection etc. as: silver-colored case.
Further task of the present utility model is finished like this: on intelligent alarm, is provided with again by 4N25, and the self-alarm and protection circuit that LM358, chips such as 4078 are formed, each chip is connected with the I/O device 8255 able to programme that is added in the 8031P1 mouth respectively.When warning device is attacked, or telephone line, when power lead is cut off, the received electric signal of input circuit will depart from the operation level of setting, the output alarm loop will start warning device immediately automatically or implement local alarm.
Because the utility model is provided with the central control circuit that is made of micro computer CPU8031, storer EPROM2732 and combinational logic circuit in alarm control unit, and be aided with three groups of functional circuits, both can pass through existing communication line, to system's Rapid Alarm such as public security, fire-fightings, and alerted parties is after receiving alarm, can carry out long-range anti-criminal to the scene by public communication network again, directly various positive restriction measures be taked at the scene of reporting to the police, for the time has been striven in various types of rescues;
Adopt detector as warning device, can make the monitoring scene be in the automatically-warning state after setting up defences, even on-the-spot generation is unusual under the unmanned state, detector still can start alarm equipment alarm automatically;
Be provided with the self-protection circuit, attacked, or telephone line, when power lead is cut off, still can starts alarm immediately automatically or implement local alarm, improve the reliability of alarm at warning device;
Be provided with uninterrupted power source, still can operate as normal under powering-off state.
Below, in conjunction with the accompanying drawings, introduce the utility model in detail.
