Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Referring to fig. 1, a flowchart illustrating steps of a first embodiment of a method for adjusting an abnormal environment in a vehicle cabin according to the present invention is shown, which may specifically include the following steps:
generally, a vehicle has four states of a starting state START, a high-power state ON, a low-power state ACC and a flameout state OFF.
102, monitoring the environment inside the carriage of the vehicle in real time to obtain real-time environment parameters if the vehicle is in the normal state;
in the embodiment of the invention, various sensors are arranged in the carriage to realize the monitoring of the environment in the carriage, so that real-time environmental parameters are obtained. For example, a temperature sensor is arranged in a carriage, and the acquired real-time environment parameter is a temperature parameter; and arranging an oxygen content sensor in the carriage, wherein the acquired real-time environment parameter is an oxygen content parameter.
103, judging whether the real-time environment parameters are in an abnormal state;
after the vehicle is turned off, the environment inside the vehicle compartment may change due to external factors, and when the environment becomes extreme, there may be a danger to people staying inside the vehicle compartment, and therefore, after obtaining the real-time environment parameters, it is necessary to determine whether the real-time environment parameters are in an abnormal state.
In an optional embodiment of the present invention, the real-time environment parameter may include a temperature parameter, and specifically, the step of determining whether the real-time environment parameter is in an abnormal state includes:
a substep 1031, determining whether the temperature parameter is higher than a first preset temperature threshold value;
substep 1032, if yes, determining that the real-time environment parameter is in a high-temperature abnormal state;
the first preset temperature threshold may be set by a technician according to actual conditions, for example, if the technician sets the first preset temperature threshold to 40 degrees celsius and the temperature parameter is 41 degrees celsius, it may be determined that the real-time parameter is in a high-temperature abnormal state. If the abnormal state of high temperature occurs, the high temperature environment in the carriage may cause the life safety endangering phenomena such as high temperature dehydration and the like of the personnel staying in the carriage.
Substep 1033, if not, determining whether the temperature parameter is lower than a second preset temperature threshold;
substep 1034, if yes, determining that the real-time environment parameter is in a low-temperature abnormal state;
the second preset temperature threshold may be set by a technician according to an actual situation, for example, if the technician sets the second preset temperature threshold to 5 degrees celsius and the temperature parameter is 5 degrees celsius, it may be determined that the real-time parameter is in a low-temperature abnormal state. If the abnormal state of low temperature occurs, the low temperature environment in the carriage may cause the life safety endangering phenomena such as temperature loss of the personnel staying in the carriage.
Sub-step 1035, if not, determines that the real-time environment parameter is not in an abnormal state.
When the temperature parameter is within the range of the first preset temperature threshold and the second preset temperature threshold, the real-time environment parameter is not in an abnormal state, the environment inside the carriage is a suitable environment, and the life safety of people in the vehicle is not endangered.
when the environment inside the vehicle compartment is detected to be abnormal, the situation that the inside of the vehicle compartment is not suitable for a person to stay is explained, and therefore whether the person stays inside the vehicle compartment or not is judged.
Specifically, the step of detecting whether a human body is present inside the compartment of the vehicle includes:
substep 1041, collecting an infrared thermal image of the interior of the compartment;
the carriage internally mounted has infrared thermal imager, can gather the inside infrared thermal image in carriage.
Sub-step 1042, judging whether the infrared thermal image has a first region conforming to the human body temperature range according to the infrared thermal image;
since humans are warm-blooded animals, generally, the body temperature of a human body is constant between 36 ℃ and 37 ℃, it is determined whether or not the infrared thermal image has a first region between the human body temperature range, and if so, the region is likely to have a human body, but there may be other objects that fit the human body temperature range. For example, if it is determined that a region between 36 ℃ and 37 ℃ exists in the infrared image, a human body may exist in the region, and the region is determined as the first region.
Sub-step 1043, if yes, intercepting a first region image of the first region from the infrared thermal image;
specifically, a first area image of a first area is intercepted from the infrared thermal image according to the temperature difference between the first area and the surrounding environment.
A substep 1043 of performing part recognition on the first region image to obtain a plurality of part temperature images;
each part of the human body has different shape outlines, so that the first area image can be subjected to part identification according to the shape outlines, and the first area image is subjected to image segmentation to obtain a plurality of part temperature images.
A substep 1044 of judging whether the plurality of part temperature images conform to the temperature distribution of the human body parts;
in substep 1045, if yes, it is determined that a human body is present inside the compartment of the vehicle.
And a substep 1046, if not, determining that no human body exists inside the compartment of the vehicle.
The temperature of different parts of a human has a steady difference. For example, the temperature of the head, hands and torso of a human body are different. Therefore, if the plurality of part temperature images match the temperature distribution of the human body part, it can be determined that the human body is present inside the vehicle compartment.
And 105, if so, adjusting the environment inside the carriage according to the abnormal state.
When the environment in the carriage is abnormal and people stay in the carriage, the environment in the carriage is adjusted to ensure the life safety of the people.
Specifically, the abnormal state is a high-temperature abnormal state, and the step of adjusting the environment inside the vehicle compartment according to the abnormal state includes:
starting a refrigeration module in an air conditioning system of the vehicle;
judging whether the temperature parameter reaches a first preset target temperature or not;
and if so, controlling the refrigeration module to maintain the temperature in the carriage at a first preset target temperature.
When the temperature in the carriage is too high and personnel exist in the carriage, the refrigeration module in the air conditioning system is started in time to reduce the temperature in the carriage to a proper temperature, so that the situations of high-temperature dehydration suffocation and the like of the personnel in the vehicle are avoided, and the safety of the personnel in the vehicle is ensured.
The abnormal state is a low-temperature abnormal state, and the step of adjusting the environment inside the vehicle cabin according to the abnormal state includes:
starting a heating module in an air conditioning system of the vehicle;
judging whether the temperature parameter reaches a second preset target temperature or not;
and if so, controlling the heating module to maintain the temperature in the carriage at the second preset target temperature.
When the temperature in the carriage is too low and personnel exist in the carriage, the heating module in the air conditioning system is started in time to raise the temperature in the carriage to an appropriate temperature, so that the conditions of low temperature and temperature loss of the personnel in the vehicle are avoided, and the safety of the personnel in the vehicle is guaranteed.
In the embodiment of the invention, whether a vehicle is in a flameout state is judged, if so, the environment inside a compartment of the vehicle is monitored in real time to obtain real-time environment parameters, whether the real-time environment parameters are in an abnormal state is judged, if so, whether a human body exists inside the compartment of the vehicle is detected, and if so, the environment inside the compartment is adjusted according to the abnormal state.
