step S2: starting a human body detection module, identifying whether personnel exist on a driving position, if not, detecting whether temporary parking time set by a vehicle owner exists, if so, detecting whether adults exist on the driving position after the temporary parking time is exceeded, and if not, executing a step S3;
and step S3: judging whether other in-vehicle members exist or not, if so, starting a camera module, acquiring in-vehicle images through the camera module, identifying identity information of the in-vehicle members, if so, executing a step S4, sending risk prompt information to an intelligent terminal of a vehicle owner, and if the sent high-risk prompt information exceeds a first set time (the time can be set by the vehicle owner and the allowed set time is 4-8 minutes), and if not, executing a step S5;
and step S4: starting a danger sensing module, wherein the steps comprise detecting temperature data, oxygen concentration and carbon monoxide concentration, and executing step S6 if the monitored data exceeds a qualified index (the temperature data is higher than a preset temperature, the oxygen concentration is lower than a preset concentration value or the carbon monoxide concentration is higher than the preset concentration value); the preset temperature value is 35-40 ℃, and the owner can freely set the temperature according to the own condition;
step S5: an alarm program in the intelligent terminal detects the mobile phone contextual model, if the mobile phone contextual model is a silent mode, the mobile phone contextual model is switched to a sound mode, and an alarm ring is sent out;
step S6: the following operations are sequentially performed: detecting whether the vehicle window is closed, if so, starting a vehicle air conditioner, keeping the interval time as second set time (which can be set to 2-5 minutes), if the temperature value, the carbon monoxide concentration or the oxygen concentration value does not reach the qualified index in the interval time, reducing the height of the vehicle window glass through a vehicle window controller, and if the temperature value, the carbon monoxide concentration or the oxygen concentration value does not reach the qualified index after reaching third set time (which can be set by a vehicle owner and the allowed set time is 4-8 minutes), executing a step S7;
step S7: light and audible alarm take place through the car light of audible and visual alarm unit control car and car loudspeaker, through speaker broadcast distress voice, drive the seat and put down the device, the control back is folding and rotate backward to the draw-in groove in, open the trunk and make the trunk upper cover rise, form escape passage, children can follow the cushion and climb backward to the trunk, leave the vehicle from the trunk again, accomplish and flee.
As shown in fig. 7, in step S1, the processor module 1 detects whether there is a temporary stop time set by the owner after detecting that the vehicle is stopped, and if so, detects whether there is a member in the vehicle to the human body detection module 6 after the temporary stop time is exceeded. Considering that the car owner may need to work temporarily and stay the children in the car, the car owner can set the temporary parking time, the human body detection module of the personnel is not started in the temporary parking time, and after the temporary parking time is exceeded, the temporary leaving time is not allowed to exceed 20 minutes.
As shown in fig. 7, in step S1, if it is detected that the engine does not stop and the vehicle stop time reaches a preset time (in order to prevent the vehicle owner from falling asleep at rest, the vehicle owner may set the rest time by himself or herself, the set time may be 10-30 minutes, and the preferred time in this embodiment is 18 minutes), it is detected whether the carbon monoxide concentration is higher than a preset concentration value, if so, the breathing data of the adult is detected by the human body detection module 6, and it is determined whether the adult is in the sleep state, if the adult is in the sleep state, the adult is awakened and warned by the speaker, and if the awakening fails, the lamps and speakers of the vehicle are controlled by the sound and light alarm unit to generate light and sound alarm. When detecting whether carbon monoxide concentration is higher than a preset concentration value, the air conditioner data are acquired through the vehicle state data acquisition module, and if the air conditioner is in an open state, the air conditioner is closed. In winter, if a person has a rest in the vehicle, but when the vehicle stops and the air conditioner is continuously opened and the vehicle door and window are closed, carbon monoxide discharged by the engine is gradually accumulated to increase the concentration of the carbon monoxide, so that poisoning occurs and even death occurs, and particularly carbon monoxide poisoning is not easily perceived in sleeping.
As shown in fig. 7, if any one of the temperature data, the oxygen concentration value or the carbon monoxide concentration value exceeds the standard, the human body detection module performs respiratory frequency detection on the in-vehicle member to obtain a respiratory frequency value, and if the respiratory frequency value exceeds or is lower than a set normal respiratory threshold, the sound-light alarm unit controls the lamps and the horn of the vehicle to generate light and sound alarm; considering that the individual constitution is different, the tolerance degree to high-temperature oxygen deficiency is different, therefore, when the temperature oxygen concentration is detected to be abnormal, the breathing frequency value of the vehicle member is detected through the human body detection module, if the breathing frequency is out of the preset value, the highest-level alarm is directly started, the health condition of the vehicle member can be more accurately monitored, and the accuracy of the alarm information is improved.
The invention has triple early warning levels, wherein the first early warning level is risk prompt information sent when children are detected to be detained, the second early warning level is that an intelligent terminal of a vehicle owner sends out alarm bell sound for prompting the vehicle owner by forcing when the feedback of the vehicle owner is not received within a period of time, and the third early warning level is that when the abnormality of temperature, oxygen or carbon monoxide is detected, a passer-by is asked for help by an audible and visual alarm, and a way of putting down a rear-row seat and opening a trunk and lifting an upper cover of the trunk is provided for the escape of the children is adopted.
It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are intended to be included within the scope of the invention as defined in the appended claims.
