Vehicle door locking prompting system and control method thereof

Abstract

The invention discloses a vehicle door locking prompting system and a control method thereof. The control method of the vehicle door locking prompting system comprises the steps that a, when a wireless signal receiver receives a vehicle door opening signal, pressure sensors on seats all start to work, and when the pressure detected by the pressure sensors reaches the preset value, the value is recorded as 1, otherwise, the value is recorded as 0, and the pressure sensors transmit the obtained detection data to a microprocessor; b, the microprocessor compares and analyzes the detection data obtained in the step a and initial data stored in a register; and c, when the sum of the detection data of the pressure sensors and the difference of the initial data are larger than 1, a master controller controls a coil of a normally-closed switch to be powered on, the normally-closed switch is switched on, and a door lock controller is powered off. When the microprocessor judges that passengers are in a vehicle, the master controller controls the coil to be powered on, the normally-closed switch is turned off, the door lock controller is disconnected with a power supply device, and finally a vehicle door cannot be closed; and a prompt can be obtained, and the passengers in the vehicle can be prevented from being locked inside mistakenly.

Description

technical field [0001] The invention relates to the technical field of vehicle door remote control devices, in particular to a vehicle door lock prompt system and a control method thereof. Background technique [0002] The remote control key of the vehicle has become a standard configuration. Cars are basically equipped with a remote control key to lock the car door. The remote control key controls the action of the door lock drive device by sending out wireless signals, and finally realizes the opening and closing of the car door. [0003] Many times, when the car owner gets off the car, he will leave the child or pet in the car. After getting off the car, the car owner will use the remote control key to close the car door. When the car key is pulled out, the car's engine has been turned off. After a period of time, the temperature inside the car will rise. High, especially in summer, if children or pets are left in the car, it will lead to tragedy. Therefore, a car door re...

[0003] Many times, when the car owner gets off the car, he will leave the child or pet in the car. After getting off the car, the car owner will use the remote control key to close the car door. When the car key is pulled out, the car's engine has been turned off. After a period of time, the temperature inside the car will rise. High, especially in summer, if children or pets are left in the car, it will lead to tragedy. Therefore, a car door remote control system that can remind the car owner is very necessary
