Detailed Description

The technical solution of the present invention is further described below by means of the accompanying drawings and examples.

The utility model provides a prevent interior personnel automatic alarm device that is detained, includes car locking device system 1, safety belt alarm system 2, power relay 3, single chip microcomputer system 4, signal detection part 5, time timer 7, alarm processing part 8 and wireless communication module 6, power relay 3's model is KH-180, time relay's model is YLS-V, single chip microcomputer system's model is AT89C51, and wireless communication module is prior art, selects conventional model just can, for example: the model FS-DTU G PRS or EMW3162 SKU 10464 wireless communication module, the alarm processing part 8 includes the anti-theft alarm vehicle system and the window control system 82, the alarm processing part 8 can drive the vehicle anti-theft alarm system 81 and the window control system 82. The window control system 82 further comprises a window stopper 821 for controlling the distance of window descending, and the window stopper 821 controls the window opening gap to be 100 mm and 200 mm. The vehicle locking device system 1 and the safety belt alarm system 2 are respectively connected with the power supply relay 3 through wires, the vehicle locking device system 1 and the safety belt alarm system 2 are existing products which are additionally arranged on a vehicle when the vehicle leaves a factory, the vehicle locking device system 1 and the safety belt alarm system 2 are auxiliary functions, the power supply relay is powered on only when the two systems transmit signals, and otherwise, the rear system does not work. The power supply relay 3 is connected with the single chip microcomputer system 4, if the vehicle lock device system 1 and the safety belt alarm system 2 are started simultaneously, the power supply relay 3 is electrified and drives the signal detection part 5 to work simultaneously, and the signal detection part 5 is provided with the infrared sensor 51 and the sound sensor 52 to confirm whether detained people exist in the vehicle. The model of the infrared sensor is RD-624 or HC-SR 501. The infrared sensor 51 is a pyroelectric infrared sensor, which is additionally arranged near a vehicle rearview mirror or a reading lamp and used for sensing whether a person or a pet stays in the vehicle, the vehicle is also internally provided with a sound sensor 52, the type of which is Y LS-V and used for detecting sound signals, and simultaneously, a power supply relay 3 is additionally arranged and used for matching with all the lifting of the windows of the vehicle, a safety belt alarm device, a loudspeaker and the like to jointly complete the processes of alarming and the windows, a signal detection part 5 is connected with the singlechip system 4 through a driving circuit and used for confirming whether the person exists in the vehicle and feeding back signals to the singlechip system 4, a wireless communication module 6 is connected with the singlechip through the driving circuit and used for calling a vehicle owner, a time timer 7 is connected with the singlechip system 4 and used for timing time, and an alarm processing part 8 is connected with the time timer, when the timer reaches the set time, the in-vehicle anti-theft alarm system 81 is started to alarm, and the window control system 82 is started to control the window to be opened.

Because other configuration facilities of the vehicle have power failure after the power supply of the conventional vehicle is locked, the safety belt alarm system 2 is connected with a power supply, and the power supply is matched with a vehicle lock control system (a lock release device) to jointly connect an additionally arranged power supply relay 3 to supply power to the safety belt alarm system when the vehicle is locked and the safety belt is unlocked.
