System and method for monitoring infants and young children in vehicles

Abstract

The present invention discloses an in-car infant monitoring system and a method, pertaining to the technical field of perception monitoring of Internet of vehicles. The system comprises a detachable label-type sensor that can be installed in the sole of an infant or on the back of the clothes of the infant and multiple monitoring node sensors installed in a car. The monitoring node sensors can beconnected with an in-car intelligent terminal and a user mobile phone to perform data interaction, the monitoring node sensors can perform monitoring and alarm on the car state and the in-car environment data, meanwhile, bluetooth can be used to determine the location of the infant with the label-type sensor, and the label-type sensor can send the location and the motion state of the label-type sensor to the monitoring node sensors. For complex situations in the practical application, the system uses an infant monitoring and alarm method on the basis of detecting scene information, so that thesystem can perform monitoring and alarm on various situations, for example, dangerous factors arises in the car environment, the infant is left in the car and the leaving time is too long, the infantfalls in the car, the infant opens the car door and strays, etc.

Description

technical field [0001] The invention relates to the technical field of perception and monitoring of the Internet of Vehicles, in particular to a system and method for monitoring infants and young children in vehicles. Background technique [0002] With the increase in the number of vehicles, cars have become an important part of family life. The safety of infants and young children in the car has always been very important. With the continuous improvement of the intelligent level of vehicles, the monitoring and protection of infants and young children in the car There is also a need for more complete and reliable development. [0003] For the monitoring and protection of infants and young children in the car, the use of safety seats is an effective and safe method. Some foreign countries have legal requirements for the use of safety seats, but due to the high price of domestic safety seats, safety seats in China The utilization rate of seats is not high, and the use of safe...

Problems solved by technology

[0003] For the monitoring and protection of infants and young children in the car, the use of safety seats is an effective and safe method. Some foreign countries have legal requirements for the use of safety seats, but due to the high price of domestic safety seats, safety seats in China The utilization rate of seats is not high, and the use of safety seats in China also faces other problems:

[0007] Publication No. CN208569840U Chinese patent discloses a life-sensing alarm device in a car, which uses crying sounds to judge infants and young children in the car. Influence, and then affect the accuracy of data processing, and when infants and young children are left in the car while sleeping, if the temperature in the car is too high, the temperature in the car will be too low, or even the oxygen concentration in the car will be too low, and other dangerous situations will not be able to be effectively detected;

[0008] The publication number is CN201820082706.0. The Chinese patent discloses a reminder seat cushion for infants trapped in the car. When environmental devices such as pressure or infrared sensors are installed under the seat, the sensor is relatively simple, and when placed on the seat and the infant Items with roughly the same weight as infants may cause false detection when they are affected by the ambient temperature and have a higher temperature, and as the age of infants increases, their weight will also increase, and the clothes worn by infants vary with the seasons. It will affect the index of weight and cause mismeasurement;

[0009] For the infrared detection method, the pyroelectric sensor uses the principle of electric polarization generated when the temperature of the crystal changes to detect thermal radiation, but the ordinary pyroelectric sensor can only be detected when the temperature difference is generated by the movement of the human body. It cannot be detected when it is stationary, so it cannot be detected when the temperature in the car is high and the infant is stationary;

[0010] For the method of using millimeter wave or other types of radar, due to the complex environment in the car and the influence of car seats and other equipment, the interference is relatively large, the accuracy of data processing is high, and it is difficult to achieve high reliability;

[0011] For the way of using wearable devices such as bracelets, the small size of the device may arouse the curiosity of infants and young children and bring new risk factors;
