Self-adaptive infrared system for monitoring internal environment of automobile

Abstract

The invention discloses a self-adaptive infrared system for monitoring the internal environment of an automobile, comprising sensors, an ECU (electronic control unit) system, a signal processing module, an analog to digital conversion circuit, a wireless communication module, an antenna and a power supply. The power supply is used for supplying power to the sensors, the ECU system, the signal processing module, the analog to digital conversion circuit, the wireless communication module and the antenna; the signals obtained by the sensors are processed by the signal processing module before being converted by the analog to digital conversion circuit, and then the signals are inputted into the ECU system; the ECU system is used for intelligently studying, analyzing and judging according to the information sensed by different sensors and the automobile key opening or locking signals obtained by the antenna; and when the environment in the automobile get worse or people / living things are left in the automobile and the automobile is locked, the ECU system is used for starting the wireless communication module to send short message to inform the occurrence of abnormal situation in the automobile. Adopting the technical scheme of the invention, the system has the intelligent fuzzy judging and adaptive learning capacity and does not need to obtain the automobile state information from the computer or other parts of the automobile.

Description

technical field [0001] The invention relates to an in-vehicle environment monitoring system, in particular to an adaptive infrared in-vehicle environment monitoring system capable of protecting life safety in the vehicle, and belongs to the technical field of automotive intelligent monitoring and life safety guarantee systems. Background technique [0002] In recent years, there have been frequent occurrences of casualties caused by out-of-control ambient temperature in the car, or spontaneous combustion of cars or excessive concentrations of carbon monoxide / carbon dioxide and other gases, such as when drivers and passengers rest or concentrate on certain activities in a closed and stationary car When the temperature rises gradually in the closed environment or the toxic gas such as carbon monoxide produced by insufficient combustion of the engine enters the compartment, the occupants of the vehicle will be poisoned and injured unknowingly, or heatstroke may be caused by the ...

Problems solved by technology

[0002] In recent years, there have been frequent occurrences of casualties caused by out-of-control ambient temperature in the car, or spontaneous combustion of cars or excessive concentrations of carbon monoxide / carbon dioxide and other gases, such as when drivers and passengers rest or concentrate on certain activities in a closed and stationary car When the temperature rises gradually in the closed environment or the toxic gas such as carbon monoxide produced by insufficient combustion of the engine enters the compartment, the occupants of the vehicle will be poisoned and injured unknowingly, or heatstroke may be caused by the temperature inside the vehicle being too high or too low. Or frostbite and freeze to death; In addition, there are still accidents caused by infants, elderly people or sleepers who are temporarily incapable of autonomy in the closed car after leaving due to the carelessness of the car owner. How to prevent such tragedies from happening There are no good measures yet, so the present invention is particularly important for realizing the continuous real-time monitoring of the internal environment of the car and ensuring the safety of the drivers and passengers
