Description
Technical Field
The invention relates to a heatstroke prevention system for missing children in a vehicle.
Background
At present, many kindergartens adopt school buses to deliver children, but sometimes the condition that the delivery personnel forget the children on the school buses occurs, in hot summer, because the interior of the school buses is closed, air cannot circulate, the temperature and the carbon dioxide concentration in the school buses can be continuously increased, and finally the children in the school buses are choked due to heatstroke or overhigh carbon dioxide concentration caused by overhigh temperature. In addition, because the temperature in the school bus is high, the school bus can be cooled only by opening the air conditioner for a long time before driving, which affects the use of the school bus.
Disclosure of Invention
The invention aims to provide a heatstroke prevention system for missing children in a vehicle, which can reduce the temperature in the vehicle and the concentration of carbon dioxide in the vehicle so as to reduce or avoid the heatstroke of the missing children in the vehicle.
The invention discloses a heatstroke prevention system for missing children in a vehicle, which comprises a controller, an automobile ignition switch, a pressure sensor for detecting the pressure above a seat in a driving seat and an air interchanger for blowing air into the vehicle; the input end of the controller is respectively connected with the automobile ignition switch and the pressure sensor, the output end of the controller is connected with the control end of the air interchanger, and the controller controls the air interchanger to work according to the automobile ignition switch and the pressure sensor.
The working principle of the heatstroke prevention system for the missing children in the vehicle is as follows:
when the driver turns off the automobile ignition switch and leaves the driver seat, the fact that the driver needs to leave the automobile or leaves the automobile is meant, the controller controls the air interchanger to work after the situation is detected by the automobile ignition switch and the pressure sensor, and air outside the automobile is conveyed to the inside of the automobile, so that the situation that the temperature of the air inside the automobile is too high, the concentration of carbon dioxide is too high and the like is avoided, and therefore even if children are left in the automobile, the children cannot be heated or suffocated, and the safety is improved. In addition, through above-mentioned breather, can make the interior temperature of car not too high, need not to start the air conditioner of longer time before driving and cool down, make things convenient for the use of school bus. The controller, the automobile ignition switch and the pressure sensor in the heatstroke prevention system for the missing children in the automobile are necessary for the existing automobile, so that an automobile owner only needs to add the air interchanger, the modification cost is very low, and the popularization and the use are facilitated.
Furthermore, the controller is provided with or connected with a timing device, and the controller can close the air interchanger after the air interchanger works for a preset time (for example, four hours) so as to avoid the storage battery feeding caused by long-time opening of the air interchanger; or the controller can only start the ventilation device in the time period with higher temperature in the day so as to avoid unnecessary waste of electric energy.
Furthermore, the ventilation device is composed of a ventilation channel arranged at the bottom of the automobile, a ventilation fan and a one-way valve in the ventilation channel, and the ventilation fan is connected with the controller. The ventilation channel is arranged at the bottom of the automobile, so that air at the shading position of the bottom of the automobile with lower temperature can be conveyed into the automobile, the temperature in the automobile is reduced, in addition, the one-way valve ensures that the air flows from the outside of the automobile to the inside of the automobile in the flowing direction, and the cold air in the automobile can be prevented from being discharged through the ventilation channel when the automobile is normally driven.
The heatstroke prevention system for the missing children in the bus can avoid overhigh temperature in the bus, effectively solves the problem of the missing children in the bus, facilitates the use of the school bus in hot summer, and has good practicability.

Detailed Description
The following describes embodiments of the present invention, such as shapes and structures of respective members, mutual positions and connection relationships between respective portions, and actions and operation principles of the respective portions, in further detail, with reference to the accompanying drawings.
Example 1:
the embodiment provides a system for preventing heatstroke by missing children in a car, which can reduce the temperature in the car and the concentration of carbon dioxide in the car so as to reduce or avoid the heatstroke by missing children in the car.
As shown in fig. 1, the system for preventing heatstroke of children left in the vehicle of the present embodiment includes a controller, a vehicle ignition switch, a pressure sensor for detecting the pressure above the seat in the driving seat, and a ventilator for blowing air into the vehicle; the input end of the controller is respectively connected with the automobile ignition switch and the pressure sensor, the output end of the controller is connected with the control end of the air interchanger, and the controller controls the air interchanger to work according to the automobile ignition switch and the pressure sensor. In this embodiment, the ventilation device is composed of a ventilation channel disposed at the bottom of the vehicle, a ventilation fan and a one-way valve in the ventilation channel, and the ventilation fan is connected to the controller. In addition, the control unit is provided with or connected to a timing device, for example a clock of a motor vehicle.
The working principle of the heatstroke prevention system for the missing children in the vehicle is as follows:
when the driver turns off the automobile ignition switch and leaves the driver seat, the fact that the driver needs to leave the automobile or leaves the automobile is meant, the controller controls the air interchanger to work after the situation is detected by the automobile ignition switch and the pressure sensor, and air outside the automobile is conveyed to the inside of the automobile, so that the situation that the temperature of the air inside the automobile is too high, the concentration of carbon dioxide is too high and the like is avoided, and therefore even if children are left in the automobile, the children cannot be heated or suffocated, and the safety is improved. In addition, through above-mentioned breather, can make the interior temperature of car not too high, need not to start the air conditioner of longer time before driving and cool down, make things convenient for the use of school bus.
The controller may turn off the ventilator after the ventilator operates for a predetermined time (e.g., four hours), or the controller may turn on the ventilator only during a time period when the temperature is high during the day, turn on the ventilator every twenty minutes, and turn off the ventilator after ten minutes of ventilation, so as to avoid battery feeding and unnecessary waste of electric energy caused by turning on the ventilator for a long time.
The ventilation channel is arranged at the bottom of the automobile, so that air at the shading position of the bottom of the automobile with lower temperature can be conveyed into the automobile, the temperature in the automobile is reduced, in addition, the one-way valve ensures that the air flows from the outside of the automobile to the inside of the automobile in the flowing direction, and the cold air in the automobile can be prevented from being discharged through the ventilation channel when the automobile is normally driven.
The invention has been described in connection with the accompanying drawings, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of the components set forth in the following description, as long as the invention is capable of being practiced without modification in any way whatsoever, and is capable of other applications without departing from the spirit and scope of the invention as defined by the appended claims.
