Description

Break line type acousto-optic monitoring device

Technical field

The utility model belongs to electronic technology and monitoring technique field, is about a kind of break line type acousto-optic monitoring device.

Background technology

Monitoring alarm device on market is of a great variety, obtains the mode of alert and mainly contains: one is the maximum infrared sensor of market share be the alarm that (adding Fresnel Lenses with pyroelectric effect device) manufacture of popping one's head in; Two be with vehicle-mounted be representative with against shock, tamper evident, noiseproof vibration displacement sensor manufacture alarm; Three be a small amount of touch, inductive probe, microwave probe manufacture alarm etc.Although the leading position that these alarms are taken precautions against in a lot of field and positive role undoubted, they also also exist certain defect in actual use really.Break line type acousto-optic monitoring device described in the utility model is by looking for another way, and it solves or compensate for some shortcoming that some supervising device on the market exists.

It is applicable to the anti-thefting monitoring of indoor and outdoor valuables, can be cut off by people at connecting line of setting up defences, break, pass through audible and visual alarm when pulling apart, be applicable to shop door and window, warehouse, market shutter door, air-conditioner outdoor unit, electric motor car etc. set up defences, to prevent stranger from stealing, effectively avoid unnecessary damage to property.Supervising device is by extraction one wires, and end points around protection place, can close through after article, or be connected on metal, once extension line is touched disconnected supervising device pass through audible and visual alarm immediately by extension line by extension line.It has practical, applied widely, this break line type acousto-optic monitoring device be a kind of cannot the anti-theft monitoring device of artificial destruction.

Below describe in detail break line type acousto-optic monitoring device described in the utility model necessity involved in implementation process, guardian technique content.

Utility model content

Goal of the invention and beneficial effect: break line type acousto-optic monitoring device described in the utility model is by looking for another way, and it solves or compensate for some shortcoming that some supervising device on the market exists.It is applicable to the anti-thefting monitoring of indoor and outdoor valuables, can be cut off by people at connecting line of setting up defences, break, pass through audible and visual alarm when pulling apart, be applicable to shop door and window, warehouse, market shutter door, air-conditioner outdoor unit, electric motor car etc. set up defences, to prevent stranger from stealing, effectively avoid unnecessary damage to property.Supervising device is by extraction one wires, and end points around protection place, can close through after article, or be connected on metal, once extension line is touched disconnected supervising device pass through audible and visual alarm immediately by extension line by extension line.It has practical, applied widely, this break line type acousto-optic monitoring device be a kind of cannot the anti-theft monitoring device of artificial destruction.

Circuit working principle: it is made up of unidirectional thyristor trigger circuit and acousto-optic circuit two parts.Resistance R1 provides base bias current for NPN type triode VT1, circuit is when the static state of alert, due to the existence of the connection wire between connection terminal TX1, connection terminal TX2, NPN type triode VT1 ends, the gate pole triggerless electric current of unidirectional thyristor SCR and turning off, follow-up acousto-optic circuit dead electricity does not work, and hummer HA is noiseless.If someone forces open the door or pivot frame and entering, connect wire to be torn, NPN type triode VT1 conducting by resistance R1 acquisition base bias current, NPN type triode VT1 emitter current triggers unidirectional thyristor SCR through resistance R2, make unidirectional thyristor SCR open-minded, namely monitoring indication light diode (LED) is lit luminescence, and namely hummer HA sends alarm sound.Because unidirectional thyristor is operated in DC loop, once open-minded, even if its gate pole loses control action, even now robber recloses connecting wire, circuit still keeps alarm condition.Only have managerial personnel to cut off direct supply just can sound all clear.Therefore, break line type acousto-optic monitoring device described in the utility model has certain anti-destructive.

Technical scheme: break line type acousto-optic monitoring device, it comprises 6V direct supply, sets up defences and biasing circuit, unidirectional thyristor trigger circuit and acoustic-optic reminding circuit, it is characterized in that:

Set up defences and biasing circuit: it is made up of connection terminal TX1 and connection terminal TX2, set up defences connecting line and resistance R1, one end of connection terminal TX1 and connecting line of setting up defences, one end of resistance R1 and the base stage of NPN type triode VT1 are connected, the other end connection circuit positive pole VCC of resistance R1, connection terminal TX2 is connected with the other end of connecting line of setting up defences and the negative electrode of unidirectional thyristor SCR;

Unidirectional thyristor trigger circuit: it is made up of NPN type triode VT1, resistance R2 and unidirectional thyristor SCR, the model that NPN type triode VT1 adopts is 2SC9014, the collector connection circuit positive pole VCC of NPN type triode VT1, the emitter of NPN type triode VT1 connects the gate pole of unidirectional thyristor SCR by resistance R2, the anode connection circuit ground GND of unidirectional thyristor SCR;
