Abstract

The utility model discloses a double safety remotely controlled anti-theft alarm which is characterized in that the ignition system of an alarm is controlled by a radio pager to enable a vehicle to be stopped, and speech alarm is realized. As the utility model can stop the vehicle and automatically alarm when the vehicle is invaded, the utility model has the double safety functions of anti-theft alarm and extinguishing.

Description

The Remote burglar alarm

The utility model relates to a kind of double insurance Remote burglar alarm with the automotive vehicles vehicle.

Present self-propelled vehicle annunciator on the market is though have function such as antitheft, anti-snatch, remote control.In case leave after 100 meters but vehicle is stolen, owner is with regard to uncontrollable annunciator.

The purpose of this utility model is to utilize modern communications technology, and radio pager is combined with annunciator, makes that annunciator can stolen to carry out remote control automobile away from the car owner flame-out and use audio alert at vehicle.Because the utility model design has the stolen and remote control alarming of stationary vehicle, so have two-way safeguarding function.

In order to achieve the above object, the utility model solution is to be designed into radio pager in annunciator, and the two-lines of vibration in the beeper or electromagnetic horn is disconnected, and the control circuit of the device that receives the report for police service gets on.Thereby make annunciator be subjected to long-distance remote control and reach the purpose of automobile flameout and warning.

Below in conjunction with accompanying drawing the utility model is further described.

Accompanying drawing has provided the circuit structure block scheme and the electrical schematic diagram of double insurance remote control alarming of the present utility model.

As noted earlier, in annunciator, be designed into radio paging receiver (1), and with on beeper (1) motor or the two-lines of electromagnetic horn disconnect, receive the input BG of latching circuit (2) ₁The b utmost point since the voltage at beeper (1) motor two ends export approximately+about 1 volt, so that BG ₁Conducting, at this moment BG ₂The b utmost point obtain bias voltage and conducting, BG simultaneously ₂E utmost point output voltage, this voltage passes through R ₂And through BG ₄Supply with BG ₂The b utmost point, make BG ₂Self-locking.+ 12V voltage passes through BG ₂And D ₁Give phonetic alarm (5) and seek vehicle radio electricity emitter (4), make voice reporting device (5) and seek car emitter (4) in running order.BG ₃Be the circuit (3) of control engine ignition, at BG ₁During the b utmost point 0 current potential, BG ₃Conducting, so ignition system is in normal working.Work as BG ₁B is BG during high potential very ₂Conducting, emitter-base bandgap grading is a high potential, voltage passes through D ₁, R ₃Give BG ₃Provide positive bias to make BG ₃End, so dot system quits work.BG ₄Be that warning and releasing for Remote latching circuit (2) designs.Short range remote control receiver (6) is after receiving the warning instruction, and output one+4V voltage also passes through R ₄Give BG ₄The b utmost point provides bias current, makes BG ₄Conducting realizes self-locking.After the warning instruction was removed ,+4V disappeared and becomes 0 current potential, so BG ₄End, at this moment BG ₂The b utmost point to uprise the position be 0 current potential, remote alarms circuit (5) is removed, self-propelled vehicle recovers normal operating condition.

BG ₅And BG ₆Constitute warning and releasing (7) after stopping.After the warning instruction took place the short range remote controller ,+4 volts of voltages were added to BG ₅The C utmost point, when sensor is not worked, BG ₅B 0 current potential very, therefore, BG ₅Belong to off condition.Because BG ₅Can not conducting, BG ₆The b utmost point do not have bias voltage to be in off condition yet.When self-propelled vehicle is prized, is opened the door, when vibration etc. is stolen, one+3～4 volts high potentials of sensor output, and pass through R ₇Give BG ₅The b utmost point bias voltage is provided, make BG ₂Conducting makes BG simultaneously ₆Also conducting.Because BG ₆Belong to power switch pipe, so the 12V power supply passes through BG ₆Supply with the power supply of alarm circuit (8), therefore sound the alarm.Throttle control circuit (10) is given on another road of 12V power supply, and throttle is closed.The time length that this part is reported to the police is decided by the time that vehicle is invaded.

Dual-safety anti-theft newspaper device principle of work of the present utility model is described below: paging receiver (1), latching circuit (2) once, flame-out control circuit (3) and seek car emitter (4), the flame-out and audio alert of the long-distance remote control when voice alarm circuit (5) is being undertaken the vehicle stolen car away from the car owner.Because the modern wireless net of exhaling covers urban and urual areas of whole country, even some national network, so, connect the number of stolen vehicle beeper immediately with phone or mobile telephone as long as find that the car of oneself is driven away, stolen vehicle controlled stop immediately in the coverage of notifying from a phone call net, and send audio alert.This is the principle of work of Remote part.Stationary vehicle is antitheft mainly by remote control receiver (6), warning and relieving circuit (7), and alarm circuit (8), sensor (9), throttle control circuit (10) is formed.Such as: prized behind the vehicle parking, car door and front and back car bonnet are opened, and car has and moves or vibration, sensor can be exported a signal immediately makes warning circuit (8) send the high pitch alarm song, simultaneously oil circuit is closed.Therefore, no matter this annunciator is in the car transfixion with stolen drive away all can auto alarm and dual-safety anti-theft function such as artificial Remote is flame-out.

Claims

1, a kind of self-propelled vehicle double insurance Remote burglar alarm that adopts mobile telephone to remove to control annunciator, it is characterized in that: the input end of the two-lines of the vibrating motor of mobile telephone or electromagnetic horn being received latching circuit (2) makes circuit controlled, thereby reaches the purpose that the Remote stolen vehicle is flame-out and report to the police.
