Abstract
The utility model relates to a theft, robbery or losing alarm which can alarm automatically. The theft, robbery or losing alarm which comprises a remote sensor and a receiving alarm discharger is suitable for storehouses, dwelling houses, vehicles, various suitcases, etc., particularly various suitcases. The utility model has the advantages of reasonable design, simple structure, small volume, low cost, accuracy and reliable alarm, high safety factor, high sensitivity, powerful antijamming capacity, less power consumption, etc.
Description
The utility model relates to and a kind ofly has that anti-theft and anti-robbing is anti-to be lost and the alarm of warning function automatically, and it is applicable to that storehouse, dwelling house, vehicle and various case and bag etc. locate, and is particularly useful for various case and bag.
It is reported that people are stolen in order to prevent goods and materials, developed various alarms, as alarm by control forms such as sound, light, induction and contact switchs.Though existing alarm has been brought into play good effect aspect antitheft, aspect anti-snatch, can't play a role effectively.In addition, also have to some extent complex structure, cost height, usability and anti-interference can difference and be subjected to weak point such as environment for use restriction.
The purpose of this utility model is, for the deficiency that overcomes above-mentioned alarm provide a kind of reasonable in design, simple in structure, volume is little, cost is low, report to the police accurately and reliably, vi have high safety, highly sensitive, antijamming capability is strong, power consumption is little, the anti-alarm of losing of the anti-theft and anti-robbing of applied range.
Technical solution of the present utility model is, in order to prevent that goods and materials are stolen, robbed, to be lost and designed a kind of alarm of being made up of remotely monitored sensor and reception warning discharger.Its remotely monitored sensor be by housing and be located in the housing recommend the carrier oscillation circuit, the stable multi-oscillation circuit is constituted.It receives the warning discharger is to be produced circuit and constituted by housing and the superregenerative detection circuit, audio frequency selective frequency amplifier circuit, emitter-base bandgap grading coupling bistable switching circuit, warning circuit, inductive proximity switch circuit, delay switch circuit, the high voltage pulse that are located in the housing.Its remotely monitored sensor is carried by the user, main identification, control warning, the anti-snatch and reminding effect of rising.Can adopt carrier frequency to cut apart in order to solve the phase mutual interference that produces between each remotely monitored sensor, modulating frequency is cut apart, and makes it can operate as normal without emitting antenna.Its receive warning discharger can be installed in the case and bag or the door and window of storehouse, dwelling house, vehicle in.Its two high-voltage pulse electrode wires that receive the warning discharger should be installed in exposed to contact key position, and two interpolars must insulate, and high-voltage pulse current can be passed through from human body, play the actuating switch effect and reach the electric shock purpose.For example be installed on the handle of case and bag or on the case and bag face, as long as meet mutually insulated between discharge electrode.Still can operate as normal when descending for the supply voltage that guarantees to receive the warning discharger, in circuit, added a radio frequency choke, therefore can make inductive switch not be subjected to the influence of mounting condition and be installed in various case and bag in easily or the door and window of storehouse, dwelling house is interior or vehicle door handle in.For easy for installation, inductor is added on the high-field electrode simultaneously, the inferior utmost point two ends of pulse transformer do not connect common ground point, are serially connected with high-voltage capacitance again in inductor and inductive proximity switch circuit simultaneously, so just can not make high-pressure electrostatic seal in the inductive proximity switch circuit and puncture oscillating tube.Be provided with the switch that has remote control and automatic control position for the ease of using flexibly on reception warning discharger.In order to prevent to lose electric shock effect, adopted the high voltage pulse that constitutes by sensitive relay, pulse transformer, contact switch to produce circuit with holding tight.In order to reduce power consumption, it is worked under very little electric current, in circuit, be provided with and swing to the complex pipe output switch circuit.
The utility model compared with the prior art, one, owing to set up and be provided with the remotely monitored sensor of recommending carrier oscillation circuit and stable multi-oscillation circuit, therefore can control artificially and receive the warning discharger.Two, produce circuit owing in receiving the warning discharger, be provided with superregenerative detection circuit, audio frequency selective frequency amplifier circuit, emitter-base bandgap grading coupling bistable switching circuit, warning circuit, inductive proximity switch circuit, delay switch circuit, high voltage pulse, so it not only has anti-theft feature and also has anti-snatch and anti-the loss and warning function automatically.And have reasonable in design, simple in structure, volume is little, cost is low, report to the police accurately and reliably, vi have high safety, highly sensitive, advantages such as antijamming capability is strong, power consumption is little, applied range.
