Specifically, target extraction can be performed on the images shot in the vehicle to obtain target extraction images, and if the target extraction images include child images, the in-vehicle state is determined as a child retention state; the waveform change rate can be determined according to the in-vehicle distance data within the preset time range, and if the waveform change rate is larger than a preset threshold value, the in-vehicle state is determined to be a child retention state.
In some embodiments, the in-vehicle state is determined as the child staying state when the child staying state exists in the determination result according to at least one of the in-vehicle captured image or the in-vehicle distance data; in some embodiments, the in-vehicle state is determined jointly according to the in-vehicle captured image and the in-vehicle distance data, that is, the in-vehicle state is determined as the child staying state only when the determination results of the in-vehicle captured image and the in-vehicle distance data are both child staying states.
In this embodiment, the vehicle detection information refers to information collected by the vehicle detection device, where the vehicle detection information includes at least one of temperature, oxygen content, and residence time, that is, the safety guarantee device 140 may be controlled according to at least one of temperature, oxygen content, and residence time, so that the safety guarantee device 140 is in a safety guarantee state to guarantee the safety of the child in the vehicle.

Further, if the in-vehicle state is the child staying state, the safety guarantee device 140 is controlled to be in the safety guarantee state according to the vehicle detection information, so as to guarantee the safety of the in-vehicle child.

The signal transmission device 141 may be a device for transmitting alarm information, including but not limited to a T-Box controller, a mobile communication device, etc. The user side refers to a terminal device used by a driver, such as a mobile phone, a tablet computer and the like.
For example, when the residence time exceeds the preset time threshold, the alarm information may be sent to the T-BOX controller and the vehicle control unit 151, and the T-BOX controller sends the alarm information to the user side of the driver. The vehicle control unit 151 may control the alarm speaker 142 disposed outside the vehicle to emit an alarm sound, and may also control the vehicle lights to flash to be found by surrounding persons.
According to the technical scheme of the embodiment of the invention, the retention time is counted by the timer 160, and the alarm information is sent to the signal sending device 141 and the vehicle control unit 151 under the condition that the retention time is greater than the preset time threshold; the signal sending device 141 sends the alarm information to the user side to remind the driver that the child is detained in the vehicle. The vehicle controller 151 may control the alarm speaker 142 to emit an alarm sound, and control the vehicle lights to flash, so as to be found by surrounding people.

and determining the waveform change rate based on the in-vehicle distance data within the preset time range, and if the waveform change rate is greater than a preset threshold value, determining the in-vehicle state as the child retention state.
On the basis of the foregoing embodiments, the controlling a safety and security device to be in a safety and security state according to vehicle detection information includes:
obtaining the temperature in the vehicle;
and under the condition that the temperature in the vehicle is higher than a first temperature threshold value, sending an exhaust trigger signal to the exhaust air exchange controller so as to control the exhaust device to exhaust air, and sending a vehicle window falling signal to the vehicle door controller so as to control the vehicle window device to fall to a safe position.
On the basis of the above embodiments, after acquiring the in-vehicle temperature, the method further includes:
and under the condition that the temperature in the vehicle is lower than a second temperature threshold value, the heating trigger signal is sent to the heating controller in the vehicle to control the heater to heat.
Illustratively, as shown in fig. 5, in the first step, it is checked whether the vehicle is turned off, and if not, the vehicle is not detected downwards and no alarm is given.
Further, if the vehicle is turned off, the detection of the door controller signal continues, unlike downstream detection if the driver's door is not open at this time.
Further, if the driver seat door is open, the downstream detection continues.
Further, when the camera and the ultrasonic radar do not detect that the detained children exist in the car, the detection is stopped;
when the camera and the ultrasonic radar are received to detect that the child is detained in the car, the timer starts to time; during this time, if the door is opened, the first step is returned.
Further, when the detention time exceeds a threshold value T1 (namely a preset time threshold value), the detention detection controller sends an alarm signal (namely alarm information) to a T-BOX controller, and the T-BOX controller can send the alarm signal to a driver and also send the alarm signal to an alarm loudspeaker arranged outside the vehicle to give an alarm sound and also send the alarm sound to the vehicle controller to turn on the vehicle lamp.
When the temperature sensor detects that the temperature is higher than the threshold value W1 (namely, the first temperature threshold value) or the oxygen sensor detects that the oxygen is lower than the threshold value O1 (namely, the oxygen content threshold value), the retention detection controller sends an exhaust command (namely, an exhaust trigger signal) to the exhaust air exchange controller, the exhaust device is started, the temperature in the vehicle can be quickly reduced, and the oxygen content in the vehicle can be quickly improved.
When the temperature sensor detects that the temperature in the vehicle is lower than a threshold value W2 (namely a second temperature threshold value), the detention detection controller sends a heating command (namely a heating trigger signal) to the heating controller in the vehicle, and after the heater receives the command, the temperature in the vehicle is rapidly heated, so that children are prevented from being injured due to low temperature.
When the temperature is detected to be higher than the threshold value W1 or the oxygen content is detected to be lower than the threshold value O1, the retention detection controller sends an exhaust starting command, and after the exhaust controller receives the command, the exhaust device is started to exhaust. At the same time, a window lowering command (i.e. a window lowering signal) is sent to the door operator, whereupon the window is lowered to a position threshold 1 (safety position).
When the temperature drops below W1, the stagnation detection controller issues a stop exhaust command to stop the exhaust action and close the window.
When the temperature is higher than W2, the stagnation detection controller issues a stop heating command to stop the heating action. During this time, if the door is opened, the first step is returned.
According to the technical scheme of the embodiment of the invention, the vehicle control signal is detected, and the in-vehicle state is judged based on the in-vehicle shooting image acquired by the camera and/or the in-vehicle distance data acquired by the ultrasonic radar under the condition that the current vehicle control signal meets the detention detection condition. Further, if the in-vehicle state is a child detention state, the safety guarantee device is controlled to be in a safety guarantee state according to the vehicle detection information so as to guarantee the safety of the in-vehicle child.
