Description

Intelligent automatic loop-locked warning device

The utility model belongs to a kind of intelligent automatic alarm system, is suitable for using in local user system, particularly small exchanger system.

In present all kinds warning device, radio or wire telegraph alarm device are arranged, be to utilize radio or wired electricity to adopt the intercommunication formula to report to the police for reporting to the police on-the-spot unmanned or warning people in case of emergency, can't send incidence of criminal offenses place and alerting signal to receiving system, also has a kind of parallel or serial digital code alarm device, as CN86201826, and the KBQ that has produced series alarm.These warning devices to fire prevention, antitheftly all can play a role, but, when wire transmission, also need independent stringing because to report to the police be to adopt coding to show that reflection is not directly perceived, increased the trouble of investment and installation and maintenance.

In view of above-mentioned prior art, the purpose of this utility model is the existing local line of a kind of utilization of design or group telephone circuit, switch, at the alarm device that does not influence purposes such as the antitheft or anti-danger of double as fire prevention under the normal situation about using of phone.This device has following advantage:

1, simple installation need not dedicated line, uses flexibly dependable performance.

2, total system does not power up (cold standby state) when alert state, does not influence the phone proper communication.

3, when the telephony switching gear switching is wrong, can discern immediately, reset rapidly, it is logical until exhaling to report to the police again, finishes the warning task.

4, be fit to emergency alarm, when in danger, do not need the field staff to speak, as long as button, nobody the time can start warning automatically by sensor, incidence of criminal offenses address or other are stored language send to receiver, and can listen to the on-the-spot sound.

But 5, site address can store arbitrarily, revise, and long preservation.

6, when receiver does not need to continue to listen to warning, receiver is resetted.

7, signalling machine can store two above telephone numbers, the touring warning.

The utility model can be added in the modulator port of ultrahigh frequency communication apparatus, is used for radio closed loop language and reports to the police automatically.

Task of the present utility model is finished like this: this device is to be made of signalling machine (caller) and receiver (called).In a group alarm system, signalling machine is a plurality of, and receiver is one, by the signalling machine activating alarm, and the receiver monitoring reception.This device also can signalling machine and receiver be combined into one the alarm that can the receive subordinate's primary network station primary alarm network alarming that can make progress again.Form by sensor or mechanical switch, electronic switch, clock-signal generator, logic control element, language switch, language synthesis unit, amplifier, identification circuit, pulse code transmitting element, status switch, impedance transformer, stabilized voltage supply as signalling machine.Receiver is made up of receipts bell circuit, monostable circuit, multivibrator, status switch, amplifier, impedance transformer, stabilized voltage supply.Closed loop recognition system of the present utility model is the logic control element by signalling machine, receipts bell circuit in pulse code transmitting element, identification circuit, status switch, impedance transformer and the receiver, monostable circuit, multivibrator, status switch, amplifier, impedance transformer are formed.The oscillator signal that multivibrator produces is an identification signal, when the pulse code transmitting element of signalling machine send ringing-current to give receiver through impedance transformer by exchange system, through receiving bell circuit start status switch the identification signal that multivibrator produces is passed through amplifier, impedance transformer and telephone line feed back to the identification circuit of signalling machine, if this multi-harmonic-oscillations frequency is within the frequency-selecting band of identification circuit frequency-selecting filter, then under the control of logic control element status switch with the control language switch, the language combiner circuit sends the language alarm signal, and via line is delivered to receiver after this signal process amplification and the impedance matching.If the frequency of the frequency-selecting filter frequency of identification circuit and multivibrator is not inconsistent or when meeting the switching equipment wrong connection then above-mentioned speech signal can not send, signalling machine can dial again until putting through under logic control element drives, form the recognition system of closed loop, finish the contact of sending and receiving news.When needing multiaddress to report to the police, then can store two above telephone number memories in some special occasions, realize automatically transferring call at the pulse code transmitting element.
