Description
Technical field
The present invention relates to a kind of burglar alarm and equipment thereof, relate in particular to a kind of burglar alarm and anti-thefting monitoring equipment thereof that is used for being undertaken during by improper opening anti-thefting monitoring at dodge gate.
Background technology
Conventional anti-theft monitoring device adopts microwave watch-dog, infrared monitor control device and ultrasonic monitor usually, be under the situation about opening when dodge gate, the user must not forget to close the primary controller that matches separately with them constantly, or remove the alarm condition of the burglar alarm that partly is made of one by these watch-dogs and separately primary controller, otherwise will produce false alarm.In addition, because these anti-theft monitoring devices are as monitored object with live animal (for example personage, animal or other dynamic object), and, the monitoring range of these anti-theft monitoring devices is restricted because of its principle of work, therefore exists the hidden danger of report to the police inaccurate (promptly failing to report alert and false alarm).
Be published in and disclose a kind of magnet controlled burglar alarm in " electric era ", the 8th phase in 1997 " magnet controlled burglar alarm " literary composition of the 9th page with open circuit and the dual warning function of short circuit acousto-optic by permanent magnet control.The core component of this anti-theft monitor is a dual operational amplifier, and just often, the tongue tube of alarm is near eternal magnet, and its contact adhesive is in closure state.When permanent magnet left tongue tube, tongue tube disconnected rapidly because of its contact of loss of excitation, or extension line is when being cut off, and the open circuit alarm circuit of alarm is connected, and the open circuit alarm lamp is bright, and loudspeaker sends chimes of doom.When extension line during by short circuit, the short-circuit alarming loop is connected, and the short-circuit alarming pilot lamp is bright, and loudspeaker sends chimes of doom.Because it is ultimate principle that magnet controlled burglar alarm is limited by permanent magnet with magnetic switch, therefore when the invador adopts the stronger magnet of magnetic to act on the magnetic switch of having set, just exist the hidden danger that magnetic switch easily lost efficacy.
Summary of the invention
The object of the present invention is to provide defective that a kind of magnetic switch of the anti-theft monitoring device that overcomes above-mentioned prior art easily lost efficacy and anti-theft monitoring device and the equipment thereof that improves the warning reliability.
In order to realize purpose of the present invention, according to a first aspect of the invention, the invention provides a kind of anti-theft monitoring device, it comprises: power supply is used for providing operating voltage to anti-theft monitoring device; The monitoring control circuit, form by first automatic reset switch that is provided with first elastic key and first capacitor, first automatic reset switch has two normally closed points, two normal battles and two common points, first end of first capacitor is connected with first common point of first automatic reset switch, and the second end ground connection of first capacitor, second common point of first automatic reset switch links to each other with the positive pole of power supply, and two normal battles of first automatic reset switch link to each other; Filtering circuit is used to suppress from undesired signals such as the random signal of monitoring control circuit and outside noises, and the capacity of the filter capacitor of filtering circuit is less than first capacitor volume; Electronic switching circuit, its power control terminal links to each other with the first normally closed point of first automatic reset switch, the input control end links to each other with the second normally closed point of first automatic reset switch, be used for when first elastic key discharges, in conducting under the control of the sparking voltage of filtered first capacitor of filtering circuit, with the output switching voltage; The coding integrated circuit is used under the control of switching voltage, adopts random code and key-encryption algorithm to produce combination pin, and password is converted to pulse-width signal and exports modulation signal; Signal sending circuit adopts the modulation signal of high-frequency oscillating circuits own coding integrated circuit in future to convert the high frequency alarm control signal to, and the emission alarm control signal; The 3rd elastic key and base, the elastic force of the 3rd elastic key is greater than the 3rd elastic key of the elastic force of first elastic key, be used to be installed in the doorframe of antitheft door, the 3rd elastic key holds out against first elastic key, wherein, when anti-theft monitoring device is in the monitoring state, first elastic key is compacted, and the normal battle of first automatic reset switch and common point are connected, and the first and second normally closed points of first automatic reset switch disconnect, electronic switching circuit is opened circuit, thereby do not provide switching voltage to the coding integrated circuit; And when first elastic key was released under monitor state, first capacitor discharged to electronic switching circuit, caused the electronic switching circuit conducting, with trigger pip transtation mission circuit emission alarm control signal.
According to a second aspect of the invention, this anti-theft monitoring device also comprises: device warning control circuit, form by second automatic reset switch that is provided with second elastic key and second capacitor, second automatic reset switch has two normally closed points, two normal battles and two common points, first end of second capacitor is connected with second common point of second automatic reset switch, the second end ground connection of second capacitor, first normally closed o'clock of second automatic reset switch links to each other with the second normally closed point of first automatic reset switch, second normally closed o'clock of second automatic reset switch links to each other with the first normally closed point of first automatic reset switch, first common point of second automatic reset switch links to each other with second common point of first automatic reset switch, and two normal battles of second automatic reset switch link to each other; Join rebasing seat, join rebasing seat matched as the base of the base of second elastic key and the 3rd elastic key, make under monitor state, first and second elastic key is all compacted, wherein, when anti-theft monitoring device is in the monitoring state always, second elastic key is compacted, and the normal battle of second automatic reset switch and common point are connected, and the first and second normally closed points of second automatic reset switch disconnect, electronic switching circuit is opened circuit, thereby do not provide switching voltage to the coding integrated circuit; When anti-theft monitoring device was disassembled under monitor state, second capacitor discharged to electronic switching circuit, caused the electronic switching circuit conducting, with trigger pip transtation mission circuit emission alarm control signal.
According to a third aspect of the invention we, the electronic switching circuit in the anti-theft monitoring device in the above-mentioned first aspect also can adopt simulation integrated switching circuit or photoelectric coupling switch circuit to realize.
According to a forth aspect of the invention, the alarm control signal that above-mentioned first the anti-theft monitoring device to the third aspect sends sends to primary controller, to send alerting signal.
According to a fifth aspect of the invention, the anti-theft monitoring device in above-mentioned first to fourth aspect also can not adopt coding integrated circuit and signal sending circuit and directly switching voltage be exported as alarm control signal.
According to a sixth aspect of the invention, the alarm control signal that the anti-theft monitoring device of above-mentioned the 5th aspect sends sends to primary controller, to send alerting signal.
Owing to adopted said structure, anti-theft monitoring device of the present invention is only just sent alarm control signal by artificial destruction under it is in the monitoring state, thereby can not produce the alert situation of failing to report, and has improved reliability.In addition, because this device has function of seismic resistance, the alert control signal of can not transmitting messages when running into sharp pounding by mistake.
