[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 - Figure 2 The utility model discloses an intelligent in-car child-forgetting prevention system, including a detection component, which is arranged in the vehicle body 1 and is used to detect environmental information in the vehicle body 1. The detection component includes a CO2 sensor 7, a temperature sensor 8 and a sound sensor 9. The CO2 sensor 7 can use a sensor module with model EY01 to obtain real-time data on the CO2 concentration in the vehicle body 1. The temperature sensor 8 can use a DS18B20 module to obtain real-time data on the temperature in the vehicle body 1. The sound sensor 9 can use a sound recognition module, or use a high-sensitivity sound sensor module to build a recognition module to obtain real-time data on the sound in the vehicle body 1.

[0023] In addition, it also includes a main control unit 6, which is a control assembly and can be made of a 51 single-chip microcomputer or an STM32 single-chip microcomputer, or other suitable chips. The main control unit 6 is electrically connected to the CO2 sensor 7, the temperature sensor 8 and the sound sensor 9. The main control unit 6 records CO2 concentration preset data, temperature preset data and sound comparison data. The CO2 concentration preset data is preferably 1600PPM, the temperature preset data is preferably 35°C, and the sound comparison data is preferably children's crying data.

[0024] In addition, in order to avoid the temperature in the vehicle body 1 being too high, causing discomfort or even heatstroke to children, an emergency fan 17 is provided at the top of the vehicle body 1. Preferably, the emergency fan 17 is located above the seat 3. The emergency fan 17 is electrically connected to the main control unit 6. When the real-time temperature data obtained by the temperature sensor 8 is greater than the preset temperature data, it means that the temperature in the vehicle body 1 has risen to a level that makes the human body uncomfortable. The main control unit 6 controls the start-up of the emergency fan 17 to cool down the children in the vehicle.

[0025] In addition, in order to prevent the CO2 concentration in the vehicle body 1 from being too high, which may cause the children in the vehicle to suffocate, a window breaking assembly is also provided in the vehicle body 1. The window breaking assembly includes a servo 15 fixed to the vehicle body 1 and a hammer 16 installed on the servo 15. The servo 15 and the hammer 16 are arranged near the vehicle window 2. The servo 15 is electrically connected to the main control unit 6. When the real-time CO2 concentration data obtained by the CO2 sensor 7 is greater than the preset CO2 concentration data, it means that the environment in the vehicle is no longer suitable for children to stay. At this time, the main control unit 6 controls the servo 15 to rotate, and the servo 15 drives the hammer 16 to swing, thereby breaking the glass of the vehicle window 2 to allow the air in the vehicle body 1 and the outside air to circulate, preventing the children from suffocating and making it easier for the children to leave the vehicle.

[0026] In addition, in order to attract the attention of people around and increase the probability of children in the car being rescued, a help-calling component is also provided outside the car. The help-calling component is electrically connected to the main control unit 6. The help-calling component includes a high-brightness light bar 18 and an MP3 module 19. The main control unit 6 can control the activation of the help-calling component, thereby calling for help from people around through the light generated by the high-brightness light bar 18 and the sound generated by the MP3 module 19, so that the children in the car can get the attention of people around.

[0027] The distress call component is triggered in the following ways: when the real-time temperature data is greater than the preset temperature data, the real-time CO2 concentration data is greater than the preset CO2 concentration data, and the real-time sound data obtained by the sound sensor 9 is similar to the sound comparison data, the distress call component is triggered when any one of these three situations, any two of these three situations, or all three situations occur together.

[0028] Furthermore, it also includes a wireless transmission module 10, which is electrically connected to the main control unit 6. A camera 11 is also provided in the car, which is electrically connected to the wireless transmission module 10. After the system is started, the wireless transmission module 10 transmits the video and sound obtained by the camera 11 to the mobile terminal 12 in real time. The mobile terminal 12 can be the parent's mobile phone, so that the parent can know the situation of the child in the car in real time. When the distress component is triggered, the wireless transmission module 10 simultaneously sends a distress signal to the mobile terminal 12 to remind the parents to rescue the children in the car in time.

[0029] In order to facilitate parents to rescue children in the car in time, the mobile terminal 12 can transmit signals with the wireless transmission module 10. The wireless transmission module 10 can also receive instructions from the mobile terminal 12 and directly activate one or all of the call for help components and the window breaking components through the main control unit 6, so as to rescue the children in the car in time and avoid the children from being put in a more dangerous situation because the parents are too far away from the children and cannot provide timely rescue.

[0030] Combine Figure 2 and Figure 3In order to improve the accuracy of CO2 concentration detection in the vehicle body 1, it is preferred that multiple CO2 sensors 7 are provided, and the multiple CO2 sensors 7 are respectively arranged on the upper side, lower side, front side and rear side of the seat 3, so as to obtain the distribution of CO2 concentration in the space around the seat 3. Then, the main control unit 6 calculates the average value of the multiple real-time CO2 concentration data, and then compares it with the preset CO2 concentration data to avoid the CO2 concentration at a certain point in the vehicle body 1 being too high, which causes the system to misjudge the information about the child's environment.

[0031] Combine Figure 2 and Figure 3 In order to improve the accuracy of temperature detection in the vehicle body 1, it is preferred that at least two temperature sensors 8 are provided, and the two temperature sensors 8 are respectively located on the upper side and the lower side of the seat 3, so as to obtain real-time temperature data of the upper space and the lower space in the vehicle body 1. The main control unit 6 then calculates the average of the two real-time temperature data and compares them with the preset temperature data to avoid the local temperature in the vehicle body 1 being too high when it is exposed to direct sunlight, which may lead to misjudgment of the temperature data of the child's environment.

[0032] Combine Figure 2 and Figure 3 In order to facilitate self-rescue of children in the car, a button A13 is provided in the car. The button A13 is electrically connected to the main control unit 6 and the steering gear 15, and the steering gear 15 is started when the button A13 is pressed. The specific process of the button A13 controlling the steering gear 15 is as follows: after the wireless transmission module 10 sends a distress signal to the mobile terminal 12, the main control unit 6 counts down, and the countdown is 30 seconds. Within 30 seconds, if it is detected that the button A13 is pressed, the steering gear 15 is directly started. If the button A13 is not detected to be pressed, the steering gear 15 is started after the countdown ends. The reason for allowing the steering gear 15 to start after the distress signal is sent is to prevent children in the car from accidentally touching the button A13. The reason for directly controlling the steering gear 15 to start at the end of the countdown is to prevent children in the car from becoming comatose and unable to save themselves.

[0033] In addition, a button B14 is provided in the vehicle, which is electrically connected to the emergency call component and the main control unit 6. When the button B14 is pressed, the emergency call component is activated. The specific process of the button B14 controlling the emergency call component is the same as the above-mentioned method of controlling the steering gear 15.

[0034] In this embodiment, in order to prevent children from accidentally touching the buttons, the button A13 and the button B14 can be installed on the back of the seat 3.

[0035] Combine Figure 1 and Figure 3In order to power the system, a power supply terminal 4 and a battery 5 are also provided on the vehicle. The power supply terminal 4 charges the battery 5, and the battery 5 supplies power to the main control unit 6, the detection component, the emergency call component, the window breaking component and the wireless transmission module 10. Optionally, the power supply terminal 4 is a solar panel or a vehicle-mounted power supply. When a solar panel is selected, the solar panel can be installed on the top of the vehicle body 1.

[0036] The working principle and usage process of the present invention are as follows: when in use, the environmental data inside the vehicle body 1 is obtained in real time through the CO2 sensor 7, the temperature sensor 8 and the sound sensor 9, and the wireless transmission module 10 transmits the video and sound obtained by the camera 11 to the mobile terminal 12 in real time. When the real-time temperature data obtained by the temperature sensor 8 is greater than the preset temperature data, the main control unit 6 controls the start of the emergency fan 17. When the real-time CO2 concentration data obtained by the CO2 sensor 7 is greater than the preset CO2 concentration data, the main control unit 6 controls the rotation of the steering gear 15, and the steering gear 15 drives the hammer 16 to swing, thereby breaking the glass of the vehicle window 2. When any one of the three situations, or any two of the three situations, or all three situations occur, the highlight light bar 18 and the MP3 module 19 are started. The mobile terminal 12 can also control the start of the steering gear 15 and the emergency call component through the wireless transmission module 10 and the main control unit 6.

[0037] In summary, the intelligent in-car child prevention system is provided with a detection component, an emergency fan 17, a window breaking component and a main control unit 6. When it is detected that the temperature in the car is too high, the main control unit 6 controls the start of the emergency fan 17 to cool down the children in the car. When it is detected that the CO2 concentration is too high, the main control unit 6 controls the start of the window breaking component to break the glass of the car window 2, so that the air in the car body 1 and the outside air can circulate, thereby preventing the child from suffocating and facilitating the child to leave the car. By providing a call for help component, a camera 11 and a wireless transmission module 10, the wireless transmission module 10 can be used to send a call in real time to the child. The video and sound captured by the camera 11 are transmitted to the mobile terminal 12 so that parents can know the situation of the children in the car in real time. When the distress component is triggered, the wireless transmission module 10 simultaneously sends a distress signal to the mobile terminal 12 to remind parents to rescue the children in the car in time. By enabling the wireless transmission module 10 to receive instructions from the mobile terminal 12, one or all of the distress components and the window breaking components are directly activated, thereby facilitating parents to rescue the children in the car in time, and avoiding the situation where parents are too far away from the children and cannot rescue them in time, causing the children to fall into more dangerous situations.
