Abstract

The present invention relates to a radio theft prevention alarm device for an automobile, which can secretly collect images. The present invention is composed of an excitation switch, a control and alarm loop, an automatic starting engine cutting loop and an automatic image collection loop. The present invention can carry out effective immediate alarm for a vehicle body and radio alarm for a room in a certain distance for two conditions of the theft attempt of a person who does not enter a vehicle and the theft operation of a person who already enters the vehicle, and meanwhile, an ignition starting circuit is cut. Besides, an automatically secret image collection function is added as required. The present invention solves the ubiquitous problems that a driver is unable to aware theft during rest when the theft occurs at night and a vehicle is parked out of doors, which vehicle is stolen, and criminal evidences can not be found.

Description

A kind of automobile radio anti-theft alarm equipment of making a video recording

The present invention relates to a kind of automobile radio anti-theft alarm equipment of making a video recording.

In the present prior art, car alarm has the function of reporting to the police when preventing the mal startup and stealing car, but being only limited to the open air reports to the police on the spot, when car owner's night's rest, can not effectively arouse vigilance, can not discern whose car and be in stolen state, can not be for finding that stealing the car criminal produces evidence.Patent application 97120255.9, " a kind of anti-theft anti-rob picture automatic tarnsmitting-recording apparatus for vehicles " provides and uses the camera record evidence of crime, and picture signal is sent to the technical scheme of control center, but there is not indoor warning function in this application, its mode is hand switch or clock relay, comparatively remarkable to the anti-abduction function in the vehicle traveling process, but the antitheft existence after stopping is not enough, and picture signal is sent the key factor that its complicated emitting antenna is the obstruction practicality with wireless system in automobile.

The objective of the invention is to as yet not into the car stealing and implemented into the car that two kinds of situations of stealing carry out that the actv. car body is reported to the police on the spot and indoor enforcement radio sound and light alarm in certain distance, cut off the ignition trigger loop simultaneously, start secret camera circuitry automatically.This function has solved that the car of probability of occurrence maximum stops the open air in the actual life; when stealing takes place in night's rest the car owner sleep soundly can't vigilance; can't discern the stolen problem of which car; indoor annunciator informs that in time the automobile of oneself has been in stolen state, cut off simultaneously the ignition trigger loop, automatically start secret camera head, the record crime positive evidence.Do not use legal key to take the driver's seat, can start warning synchronously, the above function is all active mode.

Fig. 1 is a circuit diagram of the present invention.

The automobile radio anti-theft alarm equipment of making a video recording of the present invention comprises a gauge tap 2, described control Switch 2 processed is normally closed dynamic circuit breakers lockable, as can to identify legal initiation key with of the interlock of ignition trigger lock core Contact, the break-make of this contact are not subjected to the impact of key rotation, and this contact is not in on-state when inserting key, This contact disconnected after the insertion car belonged to legal key, played identification car owner and control circuit; Comprise an electronics Vibration induction delay switch 3, pressure-sensitive switch/or human induction switch 4, described electronic vibration sense Sound and the vibration of answering the inside and outside attempt of 3 pairs of cars of delay switch to steal car are reacted, described pressure-sensitive switch/ Or human induction switch 4 is positioned at the shelter that can make to the human body of driver's cabin sensitive reaction, takes advantage of undesired React in the seat driver's seat; Comprise a vehicle-mounted short-range radio emitter 5 and radio system 6, effective transmitting range of described short-range radio emitter 5 is by most of users' stop and car The air line distance of main dwelling house can reliably be received signal and decide; Radio system 6 is audible-visual annunciators, When receiving the signal that radio transmitting apparatus 5 sends toot ring, carry or be placed on indoor by the car owner; Comprise one But individual DC relay 7 and automobile starter 8 playback minisize pick-up heads 9, open air be alarming horn 10 on the spot, Described DC relay 7 has at least one dynamic circuit breaker normally-closed contact J1 and two dynamic circuit connector normally opened contact J2, J3, But described playback minisize pick-up head 9 is installed in the hidden my place that the interior visual field of car can include the driver's seat.

The circuit connecting relation of the automobile radio anti-theft alarm equipment of making a video recording of the present invention is: electronic vibration induction time-delay switch 3 and pressure-sensitive switch/or human induction switch 4 backs in parallel and master cock 2 series connection, the combined serial after in parallel with short-range radio feedway 5 and DC relay 7 is formed the circuit cd that stealing is reacted again; Another circuit is that the moving disconnected normally closed contact J1 and the automobile starter 8 of relay 7 is composed in series the circuit ab that cuts off the ignition trigger loop when stealing; But a moving open contact J2 that closes by relay 7 is composed in series secret shooting loop with the playback minisize pick-up head; Movingly close open contact J3 and loudspeaker are composed in series open air alarm loop on the spot by one of relay 7.

Electrical component of the present invention is a dispersed placement.

Elaborate to realizing purpose of the present invention below in conjunction with Fig. 1.

Alarm principle is: ignition trigger key 1 does not insert lockhole, master cock 2 is connected, system is in and treats alert state automatically, when stealing takes place, electronic vibration induction time-delay switch 3 is connected, the contingency stealer has been forced open the door into the car on this basis, the pressure-sensitive switch in shelter in the operator's compartment/or human induction switch 4 connections, two switches are connected respectively or simultaneously and are all made circuit cd energising, vehicular radio feedway 5 is in running order, and receiving device 6 toot sound are implemented the indoor warning of radio, make relay 7 excitations simultaneously, the contact J1 of relay disconnects, and automobile can't be started; The contact J2 of relay connects, and starts secret shooting automatically; The contact J3 of relay connects open air warning device on the spot.

When not stealing generation, electronic vibration induction time-delay switch 3 and pressure-sensitive switch/or human induction switch 4 disconnections, circuit cd is the no power state, radio transmitting apparatus 5 can not be worked, relay 7 can not excitation, and contact J1 is an on-state, and contact J2, J3 are off-state.

When belonging to legal key, car inserts lockhole, contact 2 disconnects, no matter electronic vibration induction time-delay switch 3 and pressure-sensitive switch/or human induction switch 4 be in what state, circuit cd can not switch on, feedway 5 can not be worked, relay 7 can not excitation, J1 is in on-state, and the screw key ignition trigger normally carries out, and contact J2, J3 are in off-state, pick up camera can not be worked, and can not ring in open air warning device on the spot.

Power supply of the present invention is taken from automotive battery.

Under normal circumstances, each components and parts is in the no power wait state among the present invention.Realize that best mode of the present invention is by unified assembling of car manufacturer and wiring.
