The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
With reference to Fig. 1, one embodiment of the utility model car alarm is proposed, this car alarm comprises anti-theft state handover module 1, is used for the sensing module 2 of sensing signal, reporting to the police starts module 3 and alarm module 4, anti-theft state handover module 1 is used for starting or closing burglar alarm, when the user leaves car, annunciator can be made as the state of setting up defences, the warning when realizing nobody; As user onboard the time, annunciator can be made as the state of withdrawing a garrison, operate with obstruction free.
Sensing module 2 comprises infrared pickoff, shock sensor, temperature sensor and pressure sensor, and the mouth of infrared pickoff, shock sensor, temperature sensor and pressure sensor all is connected with the startup module 3 of reporting to the police.Infrared pickoff and shock sensor are installed on the vehicle body, and temperature sensor is used to detect the temperature of automobile cooling system, and pressure sensor is used to detect the air pressure of motor tire.If when someone attempts to open car door and starts automobile into the car, the infrared pickoff of sensing module 2, shock sensor be acquired signal simultaneously, and the signal that collects sent to report to the police starts module 3; When automobile is in running order, be placed in pressure sensor, the temperature sensor meeting collection site signal of automobile diverse location, with detected air pressure, temperature signal, through amplification, filtering, analogue to digital conversion, sending to reports to the police starts module 3.
The startup module 3 of reporting to the police is used to detect the electric signal that infradred sensor, shock sensor, temperature sensor and pressure sensor send.The startup module 3 of reporting to the police is a micro controller system, comprise memory device and comparator, be preset with in the memory device respectively and the cooresponding sensing contrast signal of infradred sensor, shock sensor, temperature sensor and pressure sensor, sensing signal that the different sensor that comparator is used for receiving sends and cooresponding sensing contrast signal compare, and the sensing signal that sends at sensing module 2 and cooresponding sensing contrast signal start alarm module 4 when adaptive.As sensing signal and the uncomfortable timing of cooresponding sensing contrast signal that sensing module 2 sends, represent that then automobile is in a safe condition, alarm module 4 does not start.
Alarm module 4 comprises the ignition system supply disconnecton module 44 that is installed in the car, is installed in monitoring module 45, radio alarming module 41 and wireless control module 42 in the car.Radio alarming module 41 is radio mobile communication network alarming module 4, comprise wireless alarm signal sending module 411 and wireless alarm signal receiver module 412, carry out the signal transmission by mobile communication network between wireless alarm signal sending module 411 and the wireless alarm signal receiver module 412; Wireless control module 42 is the radio mobile communication network control module, comprise wireless control signal sending module 421, wireless control signal receiver module 422 and with wireless control signal receiver module 422 bonded assembly driver modules 43, carry out the signal transmission by mobile communication network between wireless control signal sending module 421 and the wireless control signal receiver module 422, driver module 43 is electrically connected with ignition system supply disconnecton module 44, monitoring module 45 respectively; Radio alarming receiver module and wireless control signal sending module 421 are arranged in the mobile phone.Wireless alarm signal sending module 411 is used to send alerting signal, and wireless alarm signal receiver module 412 is used to receive alerting signal; Wireless control signal sending module 421 is used to transmit control signal, wireless control signal receiver module 422 is used to receive control signal, and control signal exported to driver module 43, driver module 43 comes the drive ignition system power supply to cut off module 44 according to control signal and monitors module 45.
After this alarm module 4 starts, wireless alarm signal sending module 411 just sends to alerting signal on the mobile phone that is built-in with wireless alarm signal receiver module 412 by short message mode, wireless alarm signal receiver module 412 receives alerting signal, and on mobile phone the display alarm signal, notify user's car to be in stolen state, the user can in time take effective measures and prevent that vehicle is stolen; And after the user receives alerting signal, can pass through the mobile phone input control signal, and control signal is sent by wireless control signal sending module 421, wireless control signal receiver module 422 in the car is used to receive control signal, after wireless control signal receiver module 422 receives control signal, this control signal is exported to driver module 43, driver module 43 comes the drive ignition system power supply to cut off module 44 according to control signal corresponding or monitors module 45, can make vehicle can't start or monitor the interior sound of car, make car alarm safer.
It below only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification sheets and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
