In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below by combining the specific drawings.
The inventor of the scheme discovers through a great deal of research that vehicle types of automatic air conditioners are generally provided with various environment sensors, and an air conditioner controller can continuously work for more than one hour after the vehicle is flamed out due to other functional requirements.
In view of the above, the air conditioner domain controller based on the automobile is innovative in the scheme, the characteristics of continuous work of the automobile after the automobile is flamed out are utilized, the real-time calculation is carried out according to the data of various vehicle-mounted environment sensors, the degree of severity of the environment in the automobile is judged, whether people are omitted in the automobile is judged through the change of the working condition of the automobile and the environment in the automobile, and whether related alarming and protection measures need to be taken is further comprehensively judged according to the change of the working condition of the automobile and the environment in the automobile.
Specifically, under the condition that other external equipment is not added, the control system for ensuring the safety of people staying in the vehicle is constructed by taking the vehicle body air conditioning domain controller as a core.
In the control system, the vehicle body air conditioning domain controller is in signal connection with a power system, a braking and parking system, a vehicle window control system, a seat load sensing assembly, an environment sensing system, an air conditioning system, a vehicle microphone and a vehicle T-Box system in a vehicle through a vehicle-mounted bus or a hard wire sensor, so that a vehicle working condition state signal is acquired through the vehicle body air conditioning domain controller.
By way of example, the vehicle powertrain herein includes a transmission, an engine module, an on-board battery, and the like.
The brake parking system comprises a parking assembly, a brake assembly and the like.
The window control system comprises a central control door lock, a window position sensor, a window motor and the like.
The seat load sensing assembly here mainly includes a seat load sensor and the like.
The environment sensing system mainly comprises an environment temperature sensor, an in-vehicle temperature sensor, a sunlight sensor, an in-vehicle humidity sensor, a vehicle anti-theft vibration sensor and the like.
The air conditioning system here mainly includes a compressor, a blower, and the like.
The vehicle-mounted T-Box system mainly comprises a T-Box module and the like.
Therefore, the vehicle body air conditioning domain controller serving as a processing core can acquire signal data such as an engine state signal, a door state signal (such as a door locking state), a window state signal (a window opening position), a vehicle-mounted battery power signal, a seat load sensor signal, a sunlight intensity signal, a vehicle exterior temperature signal, a vehicle exterior humidity signal, a vehicle interior temperature signal, a vehicle interior humidity signal, a vehicle interior microphone audio signal, a vehicle anti-theft vibration sensor signal, vehicle flameout time and the like of the vehicle.
According to the scheme, the vehicle body air conditioning domain controller judges the running condition of the vehicle, whether a person is detained in the vehicle and the environmental state in the vehicle according to the acquired signal data; and further judging whether the personnel staying in the vehicle have health or life risks.
When the relevant judgment results are met, alarm information is sent to the T-Box module, a vehicle owner and other relevant personnel are informed through the APP, relevant actuating mechanisms of the vehicle such as an air conditioner blower, an air conditioner fresh air door, an air conditioner compressor, an air conditioner heating system, an engine and other components are controlled, active safeguard measures are taken, and the life health and safety of people staying in the vehicle are guaranteed; the working state of the air conditioning system is controlled according to the vehicle working condition and the in-vehicle environment state dynamic state in the process, so that different active life support measures are taken according to different in-vehicle environment levels.
As an example, in order to well monitor and protect the retained personnel in the vehicle, a vehicle working condition monitoring module, an in-vehicle environment monitoring module, a retained personnel judging module and a retained personnel safety guaranteeing module are operated in a vehicle body air conditioning domain controller.
The vehicle working condition monitoring module is used for judging the vehicle working condition according to a vehicle state signal acquired by the vehicle air-conditioning domain controller, wherein the vehicle working condition comprises a vehicle power system running state, a brake parking state, a window closing state, a seat loading state and the like. Specifically, the data signal is obtained by directly obtaining the corresponding data signal by the vehicle body air conditioning domain controller, as described above, which is not described herein again.

Specifically, the data signal is obtained by directly obtaining the corresponding data signal by the vehicle body air conditioning domain controller, as described above, which is not described herein again.
The detained personnel judgment module monitors and judges whether personnel are detained in the vehicle according to the vehicle working condition monitored by the vehicle working condition monitoring module and the environment state in the vehicle monitored by the environment monitoring module in the vehicle.
For example, the detained person determining module first obtains the vehicle operating condition monitored by the vehicle operating condition monitoring module, and then obtains the in-vehicle environment state monitored by the in-vehicle environment monitoring module when the vehicle power system is closed, the door window is locked and closed and the seat bears a load, and determines whether a person is detained in the vehicle according to the in-vehicle humidity change and/or the in-vehicle audio signal. If the humidity change rate in the vehicle is abnormal and the audio signal of the microphone in the vehicle meets a specific characteristic value after the power device of the vehicle stops working (such as after the engine is shut down), the fact that related personnel are detained in the vehicle is judged, and warning information is sent out through the T-Box module according to the setting.
In cooperation with it, whether the personnel safety guarantee module that is detained has the state that personnel were detained in the car according to detaining personnel judge module monitoring judgement, combines the vehicle operating mode that vehicle operating mode monitoring module monitored and the in-car environmental condition that in-car environmental monitoring module monitored again to open air conditioning system to the operating condition of dynamic control air conditioning system realizes taking different life safety guarantee measures according to the different circumstances in the car.
For example, under the condition that the temperature in the vehicle is proper, the detained personnel safety guarantee module controls the vehicle air conditioning system to enter a fresh air mode (such as turning on an air conditioner blower), so that the accumulation of carbon dioxide in the vehicle is prevented from affecting personnel safety; simultaneously, the voltage of a vehicle-mounted storage battery in the vehicle power system is monitored in real time, when the electric quantity of the storage battery is too low and the vehicle is in a safe brake and parking (if gear judgment and parking brake are carried out), the vehicle power system is started to enter an idling working condition to charge the vehicle-mounted storage battery, so that the storage battery is prevented from feeding, and the safety of personnel in the vehicle cannot be guaranteed.
Under the condition that the environment in the vehicle is high temperature, when the detained personnel safety guarantee module confirms that the vehicle is in a safe braking parking state (if gear and parking brake are judged), the vehicle power system is started to enter an idling working condition and control the vehicle air conditioning system to enter a refrigeration cooling mode, and personnel safety in the vehicle is guaranteed for cooling the passenger compartment.
Under the circumstances that the environment in the car is microthermal, detain personnel's safety guarantee module when confirming that the vehicle is in the safety brake parking state (if judge gear and parking brake), start vehicle driving system and get into the idle speed operating mode and control vehicle air conditioning system and get into the mode of heating, heat for the passenger compartment, personnel's safety in the guarantee car.

The fourth step: and sending alarm information and taking corresponding measures.
When the vehicle body air conditioning domain controller confirms that a person stays in the vehicle, the signal pushing APP or the short message form is sent to a vehicle owner through the T-BOX module to send alarm information. And simultaneously, the vehicle body air conditioning domain controller takes different corresponding measures according to different environment levels in the vehicle:
a) under the condition that the temperature in the vehicle is proper, an air conditioner blower is turned on, and the fresh air mode is entered, so that the condition that the safety of personnel is influenced by carbon dioxide accumulation in the vehicle is prevented, meanwhile, the voltage of a storage battery is monitored in real time, and when the electric quantity of the storage battery is too low and the vehicle is safely parked (such as gear judgment and parking brake), an engine is started to enter an idling working condition to charge the battery, so that the feeding of the storage battery is prevented, and the;
b) when the environment in the vehicle is judged to be high temperature, starting the engine to enter an idling working condition when the vehicle is confirmed to be safely parked (such as gear judgment and parking brake), opening an air conditioning system to cool a passenger compartment, and ensuring the safety of personnel in the vehicle;
