technical field

The utility model relates to the technical field of vehicles, in particular to an emergency treatment device for preventing people from staying in a vehicle.

Background technique

With the popularization of automobiles, children or elderly people who lack self-rescue ability often suffocate due to being stuck in the car in summer, but it has not been effectively solved.

In response to this problem, the patent application No. CN201620125186.8, "Kindergarten School Bus with Anti-Retention Alarm System", includes: a school bus body, a vehicle sensing unit, and the vehicle sensing unit is arranged in the school bus body, including a door sensing sub-unit, and a driver System induction subunit; personnel induction unit, the personnel induction unit is arranged in the main body of the school bus, including seat induction subunit and infrared induction subunit; control unit, the control unit is arranged in the main body of the school bus, and is connected with the vehicle induction unit and the personnel induction unit Connected, according to the signal sent by the vehicle induction unit, the operation of the personnel induction unit is controlled; the alarm unit, the alarm unit is arranged on the top of the carriage and connected with the control unit. The vehicle sensing unit, the personnel sensing unit, the alarm unit and the control unit in the utility model cooperate to detect whether the school bus is parked and whether there is a person after the school bus is parked.

Patent application number CN 201220050325.7 "A school bus occupant detention alarm device and a school bus with the device", the alarm device includes at least one infrared sensor, at least one door closing sensor, engine sensor, alarm and signal processor, The output shafts of the infrared sensor, the door closing sensor and the engine sensor are connected with the input end of the signal processor, and the output shaft of the signal processor is connected with the alarm. The engine sensor, door sensor and infrared sensor send the collected signals to the signal processor. After the signal processor analyzes and processes the signal, it will drive the alarm to alarm according to the situation. The utility model can make the vehicle engine turn off and if the sensor senses that there are still occupants in the vehicle, an alarm will be issued within a few seconds after all the doors are closed, and a reminder will be made in time, so as to avoid the small occupants being stranded due to human negligence. danger in the car.

In the existing anti-retention system, it is relatively common to rely on the pressure sensor under the seat and the infrared sensor in the car to determine whether there is a retention phenomenon, but to judge the retention phenomenon through the pressure sensor, a pressure sensor needs to be installed under each seat. The cost is high, and it is common for a child's weight to be placed on the seat, which can be misjudged by the pressure sensor. In the hot summer, the infrared radiation emitted by the high temperature car hood is similar to the infrared radiation of the human body, which can easily cause the infrared sensor to misjudge or even malfunction.

To sum up, the existing anti-retention alarm device in the vehicle has the problems of high cost and false alarm. In addition, the existing anti-retention alarm device is not accurate enough to judge the parking state of the vehicle. Therefore, it is necessary to improve the existing technology to solve the above technical problems.
