Problems solved by technology
Including: 1) There is a single standard for judging leftover children, and it is easy to make mistakes in judgment and cause property losses; 2) Technologies such as automatic door opening may easily cause problems such as children getting lost and property loss in the car; 3) Children without self-rescue ability are not suitable; 3) Identifying temperature The threshold value is too high (both above 40°C) and the high temperature time is too long (both above 30 minutes), which has caused irreversible damage to children and has lost its due technical significance

Embodiment Construction
[0009] 1. Using the I2C bus communication protocol, the three-axis acceleration collected by the three-axis accelerometer is fed back to the main chip, and the main chip judges whether the car is in a stationary state through the feedback data;
[0010] 2. Once it is determined that the car is in a stationary state, start the temperature sensor, and use the I2C bus communication protocol to collect the temperature signal in the car and feed it back to the main chip. The main chip predicts whether the car will be at a high temperature by detecting the current temperature rise rate ;
[0011] 3. When it is predicted that the car will be in a high temperature state, the main chip immediately activates the infrared thermal release module, sound sensing module and ultrasonic detection module;
[0012] 4. When the infrared thermal release module detects the characteristic infrared spectrum of the human body, it will output a high level, and when the main chip detects that the infrar...

The invention discloses a device for comprehensively detecting the inside-vehicle states through a temperature sensor, a sound sensor, an ultrasonic sensor, a body infrared sensor, a three-axis acceleration sensor and various other sensors and judging whether there are children left forgotten in a vehicle in a dangerous state. The device automatically sends notice and warning to multiple parents and related guardians in time at the same time through a GPRS module and a specially-developed cell phone APP when it is judged that there are children left forgotten in the vehicle in a dangerous state and also positions the vehicle through GPS navigation so that the parents or policemen can carry out emergency rescue conveniently. By means of the device, the injuries and loss caused when the children are trapped in the vehicle in high-temperature weathers can be avoided.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a children's car safety guard system which comprehensively utilizes various sensors and communication technologies. Background technique [0002] Children are left in the car in high temperature weather, which seriously endangers the safety of children's lives. Tragedy of the end of life is not uncommon, causing great losses to families and society. With the rapid development of science and technology today, it is possible to prevent such tragedies from happening through Internet of Things related means. Through patent and knowledge retrieval at home and abroad, it is found that there are some technologies that can automatically open the door by identifying children left in the car, but there are a series of technical or practical application defects. Including: 1) There is a single standard for judging leftover children, and it is easy to make mistakes in judgment and cause...
