Description
Technical field
The utility model relates to a kind of burglar alarm, especially a kind of motorcycle anti-theft alarm.
Background technology
At present, the motorcycle anti-theft warning device of selling on the market mainly is an anti-theft alarm lock, this anti-theft alarm lock is integrated with annunciator and lock, starts the alarming horn warning of locking as long as the internal vibration sensor senses to body vibrations, will trigger immediately, this anti-theft alarm lock is easy to use, low price, wrong report must be less than releasing during the still frequency height of generation wrong report, and discovery, simultaneously can't the people under locking state for withdrawing, it is quite inconvenient to use.
The utility model content
Technical problem to be solved in the utility model provides a kind of highly sensitive, good reliability and burglar alarm easy to use.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of motorcycle anti-theft alarm comprises voltage stabilizing circuit, vibration displacement circuit, alarm circuit; Described voltage stabilizing circuit comprises the three-terminal voltage-stabilizing integration module and is connected the mouth of this module and the shunt capacitance between the ground terminal, described vibration displacement circuit comprise ND-1 type vibration displacement sensor, with the free end bonded assembly slide rheostat of this sensor and with the setting time-delay end bonded assembly delay capacitor of this sensor, described alarm circuit comprise aerotron, with transistor collector bonded assembly loud speaker and with transistor emitter bonded assembly master cock; The input end of described three-terminal voltage-stabilizing integration module is connected with power supply, mouth is connected with described ND-1 type vibration displacement sensor and described slide rheostat, the mouth of ND-1 type vibration displacement sensor is connected with the base stage of described aerotron by resistance, described loud speaker also is connected with power supply, and ND-1 type vibration displacement sensor, delay capacitor and master cock also are connected with ground.
The working process of the technical solution of the utility model:
In the driving process, master cock is in open mode, though Vehicular vibration makes the mouth of vibration displacement sensor constantly send high level signal, because master cock is opened, aerotron is in off condition, so loud speaker does not send the sound.
Behind about 30 seconds in order of the motor bike, the master cock of closing, the mouth of vibration displacement sensor sends low level signal, and aerotron still is in off condition, and this moment, loud speaker did not send the sound yet.In case cartheft vibrates by vehicle, the mouth of vibration displacement sensor will send high level signal, because master cock is closed, aerotron is conducting immediately, makes loud speaker send the sound.
Adopt the utility model that following technique effect is arranged:
1, the voltage stabilizing circuit adopts LM78 series three-terminal voltage-stabilizing IC to form constant voltage power suspply; required peripheral cell is few, and line-internal also has overcurrent, overheated and adjust the protection circuit of pipe, can provide galvanic current to press; make whole line work stable, the reliability height.
2, the vibration displacement circuit adopts ND-1 type vibration displacement sensor, inner integrated level height, and required peripheral cell is few, and periphery circuit is simple; Sense resistance is connected on the free end of vibration displacement sensor, and is highly sensitive.
