Abstract
The utility model discloses an automobile burglar alarm, comprising a monitoring system used for monitoring the change of the pressure of a parking stall and an alarming system connected with the monitoring system and used for alarming when the pressure of the parking stall changes. The monitoring system comprises a pressure sensor arranged on the parking stall and a signal emitter connected with the pressure sensor. The alarming system comprises a reception signal receiver, an A/D converter, a single-chip microcomputer, and an alarm module which are connected sequentially. The pressure sensor can detect the state of an automobile in real time. When the automobile leaves a designated area, the pressure of the area decreases; and when the weight fluctuation range reaches 30%, the automobile burglar alarm may start to use the alarming module to alarm, thereby preventing the automobile from being stolen and protecting the safety of the automobile. The system determines whether the automobile is in a safe state or not based on the fluctuation range of the pressure of the designated area and thus realizes the antitheft objective. The automobile burglar alarm is characterized by simple structure, low cost, convenient operation, and high safety factor.

Described warning system comprises the signal receiver for receiving signal projector transmitted signal, and the A/D converter, single-chip microcomputer and the alarm module that are connected successively with signal receiver.
On described alarm module, be connected with light warning module and sound alarm module.
On described alarm module, be also connected with burglary-resisting system switchgear.
On pressure transducer, be connected with power supply.
Shown in be connected with D/A converter on single-chip microcomputer, the output terminal of D/A converter is connected with the percentage by weight that increases or reduce for display automobile pressure surge and the display module of abnormal area particular location.
Compared with the prior art, the beneficial effects of the utility model are:
The car alarm that the utility model provides, can be widely used in private car garage, parking lot changes by the pressure that is arranged at the pressure transducer test parked vehicle on parking stall, in the time not obtaining car owner's instruction, be that alarm module is not while removing anti-theft modes, pressure transducer can detect the state of automobile in real time, when automobile leaves appointed area, this areal pressure reduces, when weight fluctuation range reaches 30%, system facility starts to report to the police with alarm module, and then can prevent that vehicle is stolen, protect the safety of vehicle, the utility model judges that by the fluctuation range of appointed area pressure whether automobile is in a safe condition, thereby reach antitheft object.Have simple in structure, with low cost, easy to operate, the high feature of safety coefficient.
