Problems solved by technology

[0005] 1. The precondition for alarming is that the car key is pulled out. In fact, in a hurry, it often happens that the driver turns off the engine but forgets to pull out the key and opens the door. This situation is more dangerous because others can directly enter the car at this time. Driving the car away in the car is more likely to cause property damage and even endanger the lives of children in the car

[0006] 2. Since the door is opened for a certain period of time before the alarm, in a noisy surrounding environment or when the driver leaves quickly, it is likely that the door has not been locked because the alarm has not been noticed, so there is still a potential safety hazard
