Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

In this application, the terms "comprises," "comprises," or any other variation thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements not only includes those elements, but also includes none. Other elements expressly listed, or elements inherent to such process, method, article or equipment.

It can be known from the background art that pollutants such as formaldehyde, carbon monoxide, ammonia and gas may appear indoors; these pollutants may harm the health of users.

Therefore, embodiments of the present invention provide an air conditioning control method and system. When the target gas is detected, if the concentration of the target gas is greater than the threshold and there is a user in the room, the user's physical state is obtained. When the physical condition meets the abnormal condition, the remote alarm function and the fresh air function of the air conditioner are triggered; when the physical condition does not match the abnormal condition, the air conditioner is used to output Alarm information is generated and the gas details of the target gas are determined. By monitoring the concentration of the target gas and the user's physical condition, corresponding treatment measures are determined to ensure the user's life safety.

Referring to Figure 1, a flow chart of an air conditioning control method provided by an embodiment of the present invention is shown. The air conditioning control method includes:

Step S101: When detecting the presence of target gas in the room, obtain the concentration of the target gas.

It should be noted that the target gas is any specified category of pollutant gas. For example, the target gas can be hazardous pollutant gases such as formaldehyde, ammonia, coal gas, natural gas or carbon monoxide.

During the specific implementation of step S101, a pollutant sensor installed indoors is used to monitor the gas composition in the room; when the presence of a target gas (that is, any pollutant gas) in the room is detected, the concentration of the target gas is obtained.

In some embodiments, after detecting the target gas, the category of the target gas is determined (or the target gas is defined).

Step S102: Determine whether the concentration of the target gas is greater than the concentration threshold. If the concentration of the target gas is greater than the concentration threshold, execute step S103; if the concentration of the target gas is not greater than the concentration threshold, continue to monitor the pollutant gas and return to step S101.

During the specific implementation of step S102, after obtaining the concentration of the target gas, it is determined whether the concentration of the target gas is greater than the concentration threshold, or in other words, it is determined whether the concentration of the target gas exceeds the standard.

If the concentration of the target gas is greater than the concentration threshold, it means that the concentration of the target gas exceeds the standard, and step S103 is performed at this time.

If the concentration of the target gas is not greater than the concentration threshold, it means that the concentration of the target gas does not exceed the standard. At this time, the pollution gas continues to be monitored, and step S101 is returned to execution.

Step S103: Detect whether there is a user in the room. If there is no user in the room, perform step S104; if there is a user in the room, perform step S105 and subsequent steps.

During the specific implementation of step S103, if the concentration of the target gas is greater than the concentration threshold, a human body sensor is used to detect whether there is a user in the room.

If there is no user in the room, step S104 is executed to take corresponding processing measures.

If there is a user in the room, perform step S105 and subsequent steps to take corresponding processing measures.

Step S104: Trigger the remote alarm function and the fresh air function of the air conditioner.

During the specific implementation of step S104, if the concentration of the target gas is greater than the concentration threshold and no user is detected in the room, the remote alarm function is triggered and the fresh air function of the air conditioner is triggered; wherein, triggering the remote alarm function can prompt the specified object that there is an excessive concentration in the room. of pollutant gases; triggering the fresh air function of the air conditioner can ventilate the room to reduce the concentration of indoor pollutant gases.

For example: Assume that the target gas is formaldehyde; if the concentration of formaldehyde is greater than the concentration threshold and no user is detected in the room, the trigger will be triggered. Send a remote alarm function to send the message "Formaldehyde concentration in the house exceeds the standard" to a reserved number (this information can also be pushed through the APP); at the same time, turn on the fresh air function of the air conditioner for ventilation.

Step S105: Obtain the user's physical state.

During the specific implementation of step S105, if the concentration of the target gas is greater than the concentration threshold and a user is detected in the room, a human body sensor is used to obtain the physical state of the user in the room.

Step S106: Determine whether the user's physical state meets the abnormal state. When the body state matches the abnormal state, step S107 is executed; when the body condition does not match the abnormal state, step S108 is executed.

During the specific implementation of step S106, it is determined whether the user's physical state meets any abnormal state; the abnormal state may be dizziness, vomiting, limb twitching, drowsiness, coma, etc.

If the user's physical state meets any abnormal state, step S107 is executed to take corresponding processing measures.

If the user's physical state does not meet any abnormal state, step S108 is executed to take corresponding processing measures.

Step S107: Trigger the remote alarm function and the fresh air function of the air conditioner.

During the specific implementation of step S107, if the user's physical state meets any abnormal state, the remote alarm function and the fresh air function of the air conditioner are triggered. Among them, triggering the remote alarm function can prompt designated objects to rescue users in the room; triggering the fresh air function of the air conditioner can ventilate the room and reduce the harm of polluted gases to indoor users.

For example: assuming the target gas is carbon monoxide, if the user's physical condition is consistent with a coma state; trigger the remote alarm function to send the message "the concentration of carbon monoxide in the house exceeds the standard and someone is comatose" to the reserved number; and at the same time turn on the fresh air function of the air conditioner Ventilate.

Step S108: Use the air conditioner to output alarm information and determine gas detailed information of the target gas.

During the specific implementation of step S108, if the body state does not meet any abnormal state, the speaker of the air conditioner is used to broadcast an alarm message by voice, thereby prompting the user that there is a pollutant with an excessive concentration in the room; for example: assuming that the target gas is formaldehyde; if the body When the status does not meet any abnormal status, the speaker of the air conditioner is used to broadcast the alarm message "indoor formaldehyde exceeds the standard".

After the voice alarm message is broadcast, since the physical state of the user in the room does not meet any abnormal state (the user is in a normal state), the user can judge by himself whether the fresh air function of the air conditioner needs to be turned on.

In some embodiments, after the alarm information is broadcast by voice, the specific location of the pollution source corresponding to the target gas is determined (equivalent to finding the pollution source). Specifically, the concentration of the target gas in each area in the room is determined; the area with the largest concentration of the target gas is determined to be the specific location of the pollution source corresponding to the target gas.

That is to say, the concentration of the target gas in each area of the room is first determined. The area with the largest concentration of the target gas is the specific location of the pollution source corresponding to the target gas (that is, the pollution source).

In some embodiments, after determining the specific location of the pollution source corresponding to the target gas, the speaker of the air conditioner is used to voice the specific location of the pollution source corresponding to the target gas to assist the user in quickly locating the pollution source and solving the pollution problem.

In the embodiment of the present invention, when the target gas is detected, if the concentration of the target gas is greater than the threshold and there is a user in the room, the user's physical state is obtained. When the body condition matches the abnormal state, the remote alarm function and the fresh air function of the air conditioner are triggered; when the body condition does not match the abnormal condition, the air conditioner is used to output alarm information and determine the gas details of the target gas. By monitoring the concentration of the target gas and the user's physical condition, corresponding treatment measures are determined to ensure the user's life safety.
