The embodiment of the present application provides a smart air conditioner control method, as shown in FIG. 1, including: identifying the human body tag of a user entering the room and obtaining information of the person entering the room; and adjusting the working state of the air conditioner according to the information of the indoor person.

Among them, the indoor is the control area of the air conditioner, and the indoor temperature is controlled in an appropriate range by means of the air conditioner. In the process of people entering and leaving the room, the number of people in the room changes. The number of people entering and leaving the room and the person information corresponding to each body tag are obtained by identifying the human body tags of the users entering the room, and then adjusting the working status of the air conditioner based on the changes in indoor personnel, such as the operating mode of the air conditioner , Wind speed and temperature.

The intelligent air-conditioning control method in the embodiment of the present application, after identifying the human body tag of the user entering the room, regulates the working state of the air-conditioning based on the information of the indoor personnel, so that the operating state of the air-conditioning meets everyone's indoor temperature requirements as much as possible, so that each user All feel comfortable, thereby improving the intelligence and humanization of the smart air conditioner. At the same time, adjusting the working state of the air conditioner according to the user's body tag entering the room can effectively save the energy consumption of the air conditioner and improve the working efficiency of the air conditioner.

Specifically, as shown in Fig. 2, an infrared sensing device is installed at the entrance and exit of the room. The infrared sensing device can identify human body tags and obtain the number of people entering the room. Each human body tag is an identity code, and the identity code is associated with the user’s Corresponding to gender, age, preferred temperature and preferred wind speed. After the human body tag is identified, the user's gender, age, preferred temperature and preferred wind speed information corresponding to the identity code can be retrieved for statistical analysis. The control device is signally connected with the infrared sensor device, receives the number of persons and human body tag information obtained by the infrared sensor device, and adjusts the working state of the air conditioner after analysis and processing. For example, in occasions such as libraries, cafes, and hotel conference rooms, people entering and exiting hold library cards, membership cards, or conference cards, and body tags are built into the library cards, membership cards, or conference cards. The following takes a conference room as an example for detailed description. When customizing a work card, the individual’s gender, age, and preferred air-conditioning temperature and wind speed are stored in the control device as the information corresponding to the identification code in the human body tag. When a participant enters the conference room, the infrared sensor installed at the entrance of the conference room recognizes the human body tag, obtains the human body tag of the participant, and the control device retrieves the individual information corresponding to the identity code for statistical analysis. With the help of the identified number of participants and each person’s preferred temperature, the air-conditioning temperature and wind speed are calculated through an average algorithm to fully meet the preference temperature of each participant and make each participant feel as comfortable as possible.

Among them, the infrared sensing device includes an infrared counter and an infrared sensor. Infrared sensors are used to identify human tags; infrared counters obtain the number of people entering the room. The infrared sensor can count the number of people in the room while recognizing human tags. Specifically, when a recognized human body tag appears odd number of times, the number of indoor people increases by one; when a certain recognized human body tag appears even number of times, the number of indoor people decreases by one; thus, the human body can be identified by the infrared sensor The label determines the number of people in the room.

As shown in Figure 3, when the number of people detected by the infrared counter is inconsistent with the number of people determined by the infrared sensor, that is, when a user who does not carry a human body tag enters the air-conditioning work area, the user who does not carry a human body tag will be As a tourist, the appropriate temperature is calculated based on the per capita comfortable temperature calculated by big data as the initial air conditioning parameter for each tourist. The control device corrects the temperature of the air conditioner based on the difference between the number of human tags recognized by the infrared sensor and the actual number of people obtained by the infrared counter. Specifically, the control device regards the difference between the number of human tags recognized by the infrared sensor and the actual number of people obtained by the infrared counter as the number of tourists, and performs statistics with the recognized human tags, and then calculates the appropriate working state of the air conditioner To make adjustments.

In the embodiment of the present application, the control device uses a weighted average algorithm to control the temperature and wind speed of the air conditioner according to the number, age, and initial air conditioning parameters of the people entering the room. After the infrared sensor device obtains the human body tag, it performs statistical analysis on the age and initial air-conditioning parameters contained in the human body tag, and divides the indoor personnel into three levels of elderly, middle-aged and young people according to age, and combines the weighted average algorithm to control the temperature and wind speed of the air conditioner . Specifically, the percentage of the total number of elderly people in the total number of indoor people is the weight of the elderly. The weights of the young and middle-aged and young people are determined according to the same calculation method, and the adjusted state of the air conditioner is finally determined.

In order to fully meet the needs of the elderly and young people and carry forward the traditional Chinese virtues, when using the weighted average algorithm for calculation, you can also customize the weights of the elderly, middle-aged and young people. For example, the power of the elderly is more important than that of the youth, and the power of the youth is more important than that of the young and middle-aged; of course, it is also possible to make the power of the youth more important than that of the elderly, and the power of the elderly is more important than that of the young. In addition, the elderly and young people can also be weighted as a whole. For example, the common weight of the elderly and young people is defined as 0.8 or 0.7. Correspondingly, the weight of the young and middle-aged is defined as 0.2 or 0.3. It should be noted that tourists are regarded as young and middle-aged and are determined in accordance with the status of the young and middle-aged participating in the air-conditioning work.

Preferably, the control device performs statistics on the number of people in the room and the age distribution. When the sum of the number of the elderly and young people is not less than that of the young and middle-aged, the control device performs statistical analysis on the body tag data of all the elderly and young people, using weighting The suitable temperature calculated by the average algorithm is used to control the working state of the air conditioner; when the sum of the number of the elderly and the young is less than the young and middle-aged, the control device uses a weighted average algorithm for all indoor personnel to control the working state of the air conditioner. For example, according to the preference temperature contained in the individual tag of the indoor personnel, the average algorithm is used to determine the temperature value that the air conditioner should adjust, and the temperature of the air conditioner is controlled by the control command issued by the control device; similarly, the average wind speed is used according to the preference wind speed contained in the individual tag. The algorithm determines the wind speed value of the air conditioner, and controls the operating power of the fan by the control command issued by the control device, so that the working state of the air conditioner matches the individual needs of each indoor person as much as possible, and optimizes the experience of the indoor person.
