The 7-inch TFT display 6 groups of acquisition ends are away from the number of meters of a barrier, information such as temperature and humidity is displayed, when a temperature and humidity sensor detects that the temperature is too high and severe vibration is accompanied, a control signal is sent to a single chip microcomputer U13 of a vehicle-mounted terminal, the single chip microcomputer U13 is connected with a glass window starting device or a glass crushing device of an automobile, the opening of a vehicle window is controlled or the starting of the glass crushing device is controlled, glass is crushed, enough rescue time is provided for infants to stay in the automobile due to various negligence, when the alcohol test circuit detects that the infants are drunk to drive, driving reference is provided for alarming, when an emergency situation occurs in the automobile or outside the automobile, 6 groups of cameras capture an image protection field, one-key alarm calling 110 or other personnel is achieved by using the SIM800C and a Beidou navigation module, and positioning of the automobile is sent to the people for.

The above description of the present invention is intended to be illustrative. Various modifications, additions and substitutions for the specific embodiments described may be made by those skilled in the art without departing from the scope of the invention as defined in the accompanying claims.
