Description

Technical Field

[0001] This application relates to the field of smart home appliance technology, such as a method and apparatus for controlling an air conditioner, an air conditioner, and a storage medium. Background Technology

[0002] Currently, smart homes are developing rapidly. Due to the high mobility of people in public areas, air cleaning in public areas is very complex and tedious, putting significant pressure on public areas such as shopping malls, supermarkets, and hospitals to ensure the health of users.

[0003] The related technology discloses an automatic temperature control system for bus air conditioning, including a central processor, an inlet infrared monitoring module, an outlet infrared monitoring module, an air conditioning control module, a display module, and a verification module. The central processor is responsible for receiving monitoring data from the inlet and outlet infrared monitoring modules and comparing and judging the data. The inlet infrared monitoring module is responsible for monitoring the number of passengers boarding the bus. The outlet infrared monitoring module is responsible for monitoring the number of passengers alighting the bus. The air conditioning control module is responsible for receiving control commands from the central processor and controlling the operation of the bus air conditioning system according to the corresponding commands. The display module, connected to the central processor, is responsible for displaying the temperature reduction determined by the central processor. The verification module is responsible for verifying the identity of the bus driver. This invention can adjust the temperature environment inside the bus in real time, greatly improving passenger comfort.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] Using relevant technologies, infrared monitoring modules are employed to determine the number of people inside a bus, and the air conditioner's operation is controlled based on this number, which improves the accuracy of air conditioner operation to some extent. However, in public areas, people may enter or leave side-by-side, making it difficult for the infrared monitoring module to accurately determine the number of people inside. This results in reduced air conditioner control accuracy and a poor user experience.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a method and apparatus for controlling an air conditioner, an air conditioner, and a storage medium to accurately identify the total number of people indoors, improve the accuracy of air conditioner control, and enhance the user experience.

[0009] In some embodiments, the air conditioner includes a first infrared module disposed at the indoor entrance and a second infrared module disposed at the indoor exit, both the first and second infrared modules including a plurality of sets of infrared sensors; the method includes: identifying a first number of people entering the room and a second number of people leaving the room through the first and second infrared modules respectively; determining the total number of people in the room based on the first and second numbers; and controlling the operation of the air conditioner based on the total number of people in the room.

[0010] In some embodiments, the apparatus includes a processor and a memory storing program instructions, wherein the processor is configured to execute the method for controlling an air conditioner when executing the program instructions.

[0011] In some embodiments, the air conditioner includes:

[0012] The air conditioner body includes a first infrared module located at the indoor inlet and a second infrared module located at the indoor outlet. Both the first and second infrared modules include several groups of infrared sensors spaced at predetermined intervals. The first infrared module includes a first group of infrared sensors, a second group of infrared sensors, and a third group of infrared sensors. The second infrared module includes a fourth group of infrared sensors and a fifth group of infrared sensors. Furthermore,

[0013] The aforementioned device for controlling the air conditioner is installed on the air conditioner body.

[0014] In some embodiments, the storage medium stores program instructions that, when executed, perform the aforementioned method for controlling an air conditioner.

[0015] The method and apparatus for controlling an air conditioner, the air conditioner, and the storage medium provided in this disclosure can achieve the following technical effects:

[0016] The system uses a first infrared module and a second infrared module to identify the first person entering the room and the second person leaving the room, respectively. Based on these two numbers, the total number of people in the room is determined, and finally, the air conditioner is controlled according to the total number of people in the room. Because people's walking speed and stride length vary, by setting several sets of infrared sensors at predetermined intervals at the entrance and exit, it is possible to accurately identify people walking side-by-side who could not be identified at the initial location. This allows for a more precise determination of the total number of people in the room, making the air conditioner control based on this total number of people more accurate and enhancing the user experience.

[0032] In this embodiment of the disclosure, smart home appliances refer to home appliances formed by introducing microprocessors, sensor technology and network communication technology into home appliances. They have the characteristics of intelligent control, intelligent sensing and intelligent application. The operation of smart home appliances often relies on the application and processing of modern technologies such as the Internet of Things, the Internet and electronic chips. For example, smart home appliances can be connected to electronic devices to enable users to remotely control and manage smart home appliances.

Wearable devices may include, for example, smartwatches, smart bracelets, pedometers, etc.

[0034] This disclosure provides an air conditioner comprising: a first infrared module disposed at an indoor inlet and a second infrared module disposed at an indoor outlet. Both the first and second infrared modules include a plurality of sets of infrared sensors spaced at predetermined intervals. The first infrared module includes a first set of infrared sensors, a second set of infrared sensors, and a third set of infrared sensors; the second infrared module includes a fourth set of infrared sensors, a fifth set of infrared sensors, and a sixth set of infrared sensors. The predetermined intervals can be any value, such as 39 cm, 40 cm, or 41 cm.

[0035] Combination Figure 1 As shown, this disclosure provides a method for controlling an air conditioner, including:

[0036] S01, the air conditioner identifies the first person entering the room and the second person leaving the room through the first infrared module and the second infrared module, respectively.

[0037] S02, the air conditioner determines the total number of people in the room based on the first number of people and the second number of people.

[0038] S03, the air conditioner controls its operation based on the total number of people in the room.

[0039] The air conditioner control method provided in this disclosure identifies a first number of people entering the room and a second number of people leaving the room using a first infrared module and a second infrared module, respectively. Based on the first and second numbers, the total number of people in the room is determined, and finally, the air conditioner is controlled to operate based on the total number of people in the room. Since people's walking speed and stride length vary, by setting several sets of infrared sensors at predetermined intervals at entrances and exits, it is possible to accurately identify people walking side-by-side who could not be identified at the initial location. This makes the total number of people in the room more accurate, resulting in more precise air conditioner control based on the total number of people in the room and enhancing the user experience.

[0040] Optionally, such as Figure 2 As shown, the air conditioner identifies the first person entering the room via a first infrared module, including:

[0041] S21, the air conditioner records the initial number of people entering through the first set of infrared sensors.

[0042] S22, the air conditioner records the number of people entering side by side using the second set of infrared sensors.

[0043] S23, the air conditioner determines the first person based on the initial number of people entering and the number of people entering side by side.

[0044] In this way, the air conditioner records the initial number of people entering from the initial location using a first set of infrared sensors, and records the number of people entering side-by-side using a second set of infrared sensors spaced at predetermined intervals. Since each person's stride and walking speed are different, the second set of infrared sensors at predetermined intervals can identify the number of people entering side-by-side. Thus, the air conditioner can ultimately determine the first person to enter the room based on the initial number of people entering and the number of people entering side-by-side.

[0045] Optionally, such as Figure 3 As shown, the air conditioner determines the first person based on the initial number of people entering and the number of people entering side-by-side, including:

[0046] S31, the air conditioner calculates the first sum of the initial number of people entering and the number of people entering side by side.

[0047] S32, the air conditioner determines the first sum value as the number of people.

[0048] When no people are detected sitting side by side, the number of people entering side by side is zero.

[0049] The air conditioner records the number of people entering side-by-side using a second set of infrared sensors, including: the air conditioner detects the second number of people entering at a second location within a set time period using the second set of infrared sensors; if the number of people entering is greater than the number of people entering initially, the air conditioner determines that there are people entering side-by-side; if there are people leaving side-by-side, the air conditioner calculates the difference between the number of people entering and the number of people entering initially; the air conditioner determines the difference between the number of people entering and the number of people entering side-by-side as the number of people entering side-by-side.

[0050] In this way, the air conditioner calculates the initial number of people entering and the first sum of the number of people entering side by side, and determines the first sum as the first number. By correcting the initial number of people entering side by side, the actual number of people entering the room can be accurately obtained.

[0051] Optionally, such as Figure 4 As shown, after determining the first person based on the initial number of people entering and the number of people entering side-by-side, the air conditioner also includes:

[0052] S41, the air conditioner uses a third set of infrared sensors to determine the number of people entering the room.

[0053] S42, if the number of third people is greater than the number of first people, the third person is determined to be the new number of first people.

[0054] In this way, after the air conditioner determines the first number of people based on the initial number of people entering and the number of people entering side-by-side, there is still a small probability that people walking side-by-side will not be detected at the second set of infrared sensors. Therefore, the first number is corrected by the third set of infrared sensors. If the third number is greater than the first number, it indicates that there are undetected side-by-side people entering at the first and second sets of infrared sensors. Therefore, the third number is determined as the new first number. By adding a third set of infrared sensors to correct the first number, accurate identification of the number of people entering the room is achieved, improving the accuracy of air conditioner control.

[0055] Optionally, the air conditioner identifies a second person entering or leaving the room via a second infrared module, including:

[0056] S51, the air conditioner records the initial number of people leaving through the fourth set of infrared sensors.

[0057] S52, the air conditioner records and counts the number of people leaving through the fifth set of infrared sensors.

[0058] S53, the air conditioner determines the second number of people based on the initial number of people leaving and the number of people leaving side by side.

[0059] In this way, the air conditioner records the initial number of people leaving using the fourth set of infrared sensors, and the number of people leaving side-by-side using the fifth set of infrared sensors. Finally, based on the initial number of people leaving and the number of people leaving side-by-side, the air conditioner determines the second number of people entering the room. Since each person's stride and walking speed are different, the fourth set of infrared sensors, which are spaced at predetermined intervals, can identify the number of people standing side-by-side. Thus, the air conditioner can ultimately determine the second number of people entering the room based on the initial number of people leaving and the number of people leaving side-by-side.

[0060] Optionally, the air conditioner determines a second number of people based on the initial number of people leaving and the number of people leaving side by side, including: the air conditioner calculating a second sum of the initial number of people leaving and the number of people leaving side by side; the air conditioner determining the second sum as the second number of people.

[0061] When no people are detected sitting side-by-side, the number of people leaving side-by-side is zero.

[0062] The air conditioner records the number of people leaving side by side using the fourth set of infrared sensors, including: the air conditioner detects the second number of people leaving at the fifth position within a set time period using the fourth set of infrared sensors; if the second number of people leaving is greater than the initial number of people leaving, the air conditioner determines that there are people leaving side by side; if there are people leaving side by side, the air conditioner calculates the difference between the second number of people leaving and the initial number of people leaving; the air conditioner determines the difference between the number of people leaving and the number of people leaving side by side as the number of people leaving side by side.

[0063] In this way, the air conditioner calculates the second sum of the initial number of people leaving and the number of people leaving side by side, and determines the second sum as the second number. By correcting the initial number of people leaving side by side, the actual number of people leaving the room can be accurately obtained.

[0064] Optionally, after determining the first number of people based on the initial number of people leaving and the number of people leaving side by side, the air conditioner further includes: determining the fourth number of people leaving the room through the sixth set of infrared sensors; if the fourth number of people is greater than the second number of people, the air conditioner determines the fourth number of people as the new second number of people.

[0065] In this way, after the air conditioner determines the second number of people based on the initial number of people leaving and the number of people leaving side-by-side, there is still a small probability that people walking side-by-side will not be detected at the fifth set of infrared sensors. Therefore, the second number is corrected by the sixth set of infrared sensors. If the fourth number is greater than the second number, it means that there are undetected people leaving side-by-side at the fourth and fifth sets of infrared sensors. Therefore, the fourth number is determined as the new first number. By adding a sixth set of infrared sensors to correct the second number, accurate identification of the number of people leaving the room is achieved, improving the accuracy of air conditioner control.

[0066] Optionally, the air conditioner determines the total number of people in the room based on the first number of people and the second number of people, including: the air conditioner obtaining the difference between the first number of people and the second number of people; the air conditioner calculating the sum of the difference in the number of people and the currently recorded number of people in the room; and the air conditioner determining the sum of the number of people as the total number of people in the room.

[0067] In this way, the air conditioner obtains the difference between the first and second number of people, and can determine the increase or decrease in the total number of people in the room. The air conditioner calculates the sum of the number difference and the currently recorded number of people in the room, and finally determines the total number of people in the room, thus obtaining the current total number of people in the room.

[0068] Optionally, the air conditioner controls its operation based on the total number of people in the room, including: when the total number of people in the room is less than a set threshold, the air conditioner activates a fresh air mode; when the total number of people in the room is greater than or equal to the set threshold, the air conditioner activates both a fresh air mode and an air washing mode.

[0069] The set threshold for the number of people can be any value, such as 45, 50, or 55 people. When the total number of people in the room is less than the second set threshold, the air conditioner will shut off the fresh air mode and air washing mode to avoid wasting energy. The second set threshold for the number of people can also be any value, such as 19, 20, or 21 people.

[0070] In this way, when the total number of people in the room is less than a set threshold, the air conditioner activates the fresh air mode. When the total number of people in the room is greater than or equal to the set threshold, it activates both the fresh air mode and the air washing mode. By controlling the air conditioner to operate in either fresh air mode or a combination of fresh air and air washing modes based on the total number of people in the room, the indoor air quality can be matched with the current number of people in the room. This improves the accuracy of air conditioner control, keeps the indoor air fresh, ensures the health of users, and enhances the user experience.
