Description
Technical field
the utility model relates to a kind of warning device, especially can effectively prevent the storage battery antitheft alarm system that the battery-driven car storage battery is stolen.
Background technology
are present, do not have the failure-free anti-joyride device on the known battery-driven car, and the thief are more and more rampant to the pilferage of battery-driven car storage battery, brings very big puzzlement for people's life.
The utility model content
are in order to overcome the problem that the battery-driven car storage battery is stolen easily; The utility model provides a kind of storage battery antitheft alarm system; This device can in time be reported to the police rapidly, prevents that effectively the storage battery of battery-driven car from being stolen, and offers convenience for people's life.
the utility model solves the technical scheme that its technical matters adopted: this storage battery antitheft alarm system comprises digital pressure sensor, micro controller system, switch and loud speaker; Bottom at the battery-driven car storage battery is provided with digital pressure sensor, and digital pressure sensor is electrically connected through the lead coupling with micro controller system, switch and loud speaker successively.
The 1 pin VDDA of
digital pressure sensor connects power supply VCC through the electric capacity of 100nF, and power supply VCC can supply power for digital pressure sensor, keeps chip operation; 5 pin SCL of digital pressure sensor and 6 pin SDA pass through the pull-up resistor power connection VCC of 10K respectively; 5 pin SCL of digital pressure sensor connect 1 pin P1.0 of micro controller system; 6 pin SDA of digital pressure sensor connect 2 pin P1.1 of micro controller system; 7 pin XCLR of digital pressure sensor connect 3 pin P1.2 of micro controller system, and digital pressure sensor can communicate with micro controller system, and real-time sends the detected pressure signal of pressure sensor to micro controller system.
18 pins of
micro controller system link to each other with crystal oscillating circuit with 19 pins, and crystal oscillating circuit is that micro controller system provides clock signal, guarantee the micro controller system normal operation; 40 pin Vcc of micro controller system are connected with power supply through electric capacity and the switch S 1 of a 0.1u, 20 pin Vss ground connection of micro controller system, through switch S 1 can control single chip computer unlatching and shutoff; The resistance of 21 pins of micro controller system through 1K connects the transistorized base stage of PNP, and the transistorized emitter of PNP links to each other with a loud speaker that is connected to power supply, the transistorized grounded collector of PNP, through micro controller system can control loudspeaker startup and shutoff.
are installed in an osed top with digital pressure sensor and have in the container of piston, and storage battery is pressed in the top of piston, make the bar pressure in the container higher, and this moment, digital pressure sensor can detect the bar pressure in the container; If there is the people to steal storage battery; The pressure that then is applied on the piston disappears; Bar pressure moment that digital pressure sensor detects in the container reduces, when micro controller system receives force value when being reduced to certain numerical value, high level of 21 pins output of micro controller system; Start loud speaker, warning device begins to report to the police.
The beneficial effect of
the utility model is that this device can in time be reported to the police rapidly, prevents that effectively the storage battery of battery-driven car from being stolen, and offers convenience for people's life.
