Abstract
An antitheft alarm for vehicles without false alarm is an antitheft alarm for vehicles. The utility model provides an antitheft alarm for vehicles, which can effectively prevent theft and false alarm, Compared with a traditional antitheft alarm, the utility model is characterized in that one vehicle running state sensor is adopted and is arranged on a position which is relevant to vehicle running or wheel rotation. Mileage alarm can be preset. The alarm can also be connected with a door and window damage detector to reinforce antitheft functions. The installation means of the utility model is multiple and hidden, therefore whether the antitheft alarm is arranged on the vehicle can not be judged in advance but be determined when the vehicle is started. Therefore, as long as a part of vehicles in one city are provided with the antitheft alarm of the utility model, the vehicles can be effectively prevented from being stolen. In addition, because only when the vehicle is damaged, the utility model can alarm, the false alarm of the alarm is completely prevented. If the preset mileage alarm is added, the utility model can also be used for hijacking resistance alarm.
Description
Affiliated technical field
The utility model relates to a kind of car alarm.Particularly a kind of car alarm that does not have flase alarm.
Background technology
At present, car alarm all adopts vibration sensor to report to the police, and transducer sensitivity is low, can not be effectively antitheft; And sensitivity has been provided with height, has vibration to report to the police slightly, crosses an automobile even and will report by mistake.During blowing and raining, cab warning is mad to make more than situation of common occurrence.Especially near resident's rest having a strong impact on night.The automobile that dwelling district is parked often suffers the complaint of resident family owing to the wrong report at night, even is destroyed by the resident of indignation.In light of this situation, some local government prohibites the automobile that is parked in dwelling district and opens annunciator night, and can only take alternate manner antitheft.Burglar alarm has become ornaments.The traditional alert device is owing to be difficult to take into account sensitivity and wrong report problem, thereby is difficult to solve contradiction antitheft and that report by mistake.
The purpose of utility model
The purpose of this utility model provides a kind of not only effectively antitheft but also can prevent the car alarm reported by mistake.The burglar alarm of technical scheme utility model and traditional burglar alarm difference are to have adopted the motoring condition sensor.The motoring condition sensor is installed on the position relevant with running car or wheel.The motoring condition sensor can be 1. to be installed in the pulse detector or the level detector of mileage meter or speed meter inlet wire; Or 2. show state sensor that detects mileage meter or speed meter, if certain field in 7 sections demonstrations of last bit digital of detection digital watch, level or level as a section change, or detect the change in location of simulating list index, can realize that all the show state of mileage meter or speed meter becomes the detection of motoring condition; Or the wheel rotation sensor of the suitable position installation of 3. car bodies, as opto-electronic pickup, magnetic induction sensor etc., whether rotate the judgement motoring condition by detecting wheel.3 technical schemes all can preset mileage and report to the police.Describe in detail below the presetting mileage and can directly be provided with of technical scheme 2, technical scheme 1,3.Automobile is not reported to the police at ordinary times, and only automotive wheel rotates when running car, or certain fare register that travels is just reported to the police.
The type of alarm of utility model can adopt special-purpose alarming horn, also can receive on the horn trumpet, preferably all is connected with horn trumpet, front and back lamp, in case stolen, sound and light alarm can prevent that automobile is stolen.Also can adopt the radio alarming form, make alerting signal be sent to car owner's mobile phone or public security organ.Annunciator can also have firing circuit and the oil circuit device that cuts off automobile, cuts off the firing circuit of automobile in the time of warning, even oil circuit, and it is stolen that the automobile actv. is prevented.Alarm switch can wireless remote control, also can be installed in the concealment part of automotive interior.Annunciator can also connect door and window and destroy detector, strengthens anti-theft feature.Beneficial effect
The advantage of utility model is that mounting means is various and hidden, thereby can't judge in advance whether automobile installs burglar alarm, only starts automobile and could determine.So, can prevent effectively that automobile is stolen as long as a city has the part automobile that the burglar alarm of this project is installed.In addition, owing to just report to the police when having only automobile destroyed or stolen, thereby prevented the wrong report of annunciator up hill and dale.Preset the mileage warning if increase, also can be used for anti-hijacking and report to the police.
The drawing explanation
Fig. 1 is the block scheme that utility model adopts a kind of embodiment of pulse detector.
Fig. 2 is the block scheme that utility model adopts a kind of embodiment of wheel rotation sensor.
The contrast accompanying drawing is described utility model in detail
With reference to Fig. 1, in the empty frame is the car alarm electrical block diagram of no flase alarm, annunciator is connected on the mileage meter inlet wire according to technical scheme 1, when mileage meter is passed in pulse, detected by pulse detector, and by pulse totalizer counting, when reaching presetting pulse and counting, control unit drives horn trumpet, car bulb, sound and light alarm; And cut off circuit, oil circuit.Reach delayed alarm, can be used for anti-hijacking and report to the police.Technical scheme 3 also can adopt Fig. 1, and only pulse totalizer is connected on the wheel rotation sensor back, rather than the pulse detector back.
With reference to Fig. 2, in the empty frame is the car alarm electrical block diagram of no flase alarm, annunciator has adopted opto-electronic pickup as wheel rotation sensor according to technical scheme 3, and increased door and window and destroyed detector, destroy by detecting wheel and door and window, control unit drives horn trumpet, car bulb, sound and light alarm; And cut off circuit, oil circuit.
