[0036] Please refer to the following Figure 1 , a method for controlling an air conditioner provided by an embodiment of the present invention specifically includes: steps S101 to S105.

[0037] Step S101, collect indoor heat source information and indoor ambient temperature, and obtain a preset target temperature;

[0038] Step S102, set the target operating parameters of the air conditioner in combination with the indoor heat source information and the indoor ambient temperature;

[0039] Step S103, control the operation of the air conditioner based on the target operating parameters, and continue to collect the indoor heat source information and the indoor ambient temperature during the operation;

[0040] Step S104, use the indoor ambient temperature to determine whether the target temperature is reached, obtain a temperature determination result, and determine whether to send a reminder instruction to close the doors and windows according to the temperature determination result;

[0041] Step S105, use the indoor heat source information to determine whether there are people in the room, obtain a personnel determination result, and determine whether to control the air conditioner to stop operating according to the personnel determination result.

[0042] In this embodiment, first, collect indoor heat source information and indoor ambient temperature, and set the target operating parameters of the air conditioner in combination with the set target temperature, so that the air conditioner operates based on the target operating parameters. Thereafter, continue to collect indoor heat source information and indoor ambient temperature, so as to judge whether the room doors and windows are closed based on the indoor ambient temperature and the preset target temperature, and generate a reminder instruction to close the doors and windows for reminding the user to close the doors and windows when it is determined that they are not closed, and judge the number of indoor personnel based on the indoor heat source information, and stop operating when there is no one in the room. In this way, it is possible to solve the problem of high power consumption of the air conditioner when the room doors and windows are not closed compared to the normal state, and solve the problem of high power consumption of the air conditioner not being turned off for a long time when there is no one in the room, thereby improving the energy-saving effect of the air conditioner and achieving the purpose of enhancing the control effect of the air conditioner.

[0043] In an actual application scenario, the infrared radiation information of various indoor objects can be collected through a heat source sensing module integrated on the air conditioner, and the infrared radiation information is converted into an electrical signal by an infrared sensor, so as to achieve the effect of collecting the indoor heat source temperature and distribution. The indoor environmental temperature can also be collected through the temperature sensing bulb and control chip on the indoor unit module of the air conditioner, and the set target temperature can be obtained. Optionally, the implementation subject of the air conditioner control method provided in this embodiment can be the air conditioner itself, or a server or service terminal connected by communication. For example, after collecting the indoor heat source information and indoor environmental temperature, it can be sent to the cloud server through communication connection, and then the cloud server performs corresponding processing, such as comparing temperatures, judging whether the doors and windows are closed, and judging the number of indoor people, etc. Further, the air conditioner or the cloud server can also be connected to the user's smart terminal, so that when a door / window closing reminder instruction is issued, the user can be reminded to close the doors and windows in time to reduce the energy consumption loss of the air conditioner.

[0044] In one embodiment, step S102 includes:

[0045] Calculate the required target cooling capacity for the room according to the following formula:

[0046] Q = Q b + Q ma + Q o ;

[0047] Q b = ρ × V × c × (T env - T set );

[0048] Q ma = Q m × N;

[0049] Q o = Q i × n i ;

[0050] Wherein, Q represents the target cooling capacity, Q b represents the single temperature difference cooling capacity, Q ma represents the additional cooling capacity of human heat sources, Q o represents the cooling capacity of heat source loads, ρ represents the air density, V represents the room volume, c represents the specific heat capacity of air, T env represents the indoor environmental temperature, T set represents the target temperature, Q m represents the heat load of a single human heat source, N represents the total number of people, Q i represents the heat load of the i-th object heat source, n i represents the total number of the i-th object heat sources;

[0051] Set the compressor frequency and the rotation speed of the indoor fan of the air conditioner according to the target cooling capacity, and use the set compressor frequency and the rotation speed of the indoor fan as the target operating parameters.

[0052] In this embodiment, when setting the target operating parameters, the single-temperature-difference cooling capacity Q b , the additional cooling capacity Q ma due to human heat sources, and the cooling capacity Q o of the heat source load can be calculated separately first. Among them, the single-temperature-difference cooling capacity Q b refers to the cooling capacity required according to the room temperature and the air conditioner set temperature; the additional cooling capacity Q ma due to human heat sources refers to, for the number of people information in the room, after detecting the number of people N through the heat source sensing module, and then based on the heat load Qm of a single human heat source in the cloud server, obtaining the additional cooling capacity required for the room; the cooling capacity Q o [[ID= fifteen]]of the heat source load refers to the total additional heat source load other than human heat sources. For example, there are two mobile phone chargers in the room, with a surface temperature of 40-50°C and a sensing area of 0.01 m 2 , and the corresponding heat load is Q1, and one TV, with a surface temperature of 30-40°C and a sensing area of 0.5 m 2 , and the corresponding heat load is Q2. Then the total additional heat source load is Q o = 2×Q1 + Q2.

[0053] After obtaining the single-temperature-difference cooling capacity Q b , the additional cooling capacity Q ma due to human heat sources, and the cooling capacity Q o of the heat source load, add the three to obtain the target cooling capacity required indoors. Subsequently, set the operating frequency of the compressor of the air conditioner according to the target cooling capacity. At the same time, the rotation speed of the indoor fan of the air conditioner has a positive correlation with the operating frequency of the compressor. In this way, the rotation speed of the indoor fan can also be set. For example, usually, the operating frequency of the compressor is 30-120 Hz, and the rotation speed of the indoor fan is usually 200-1200 rpm. Therefore, when the compressor frequency is set to increase by 1 Hz, the fan speed increases by 11 rpm.

[0054] In one embodiment, as Figure 2 shown, step S104 includes: steps S201-S204.

[0055] Step S201, when the indoor environmental temperature reaches the target temperature within the preset target time, control the air conditioner to continue running in the current state;

[0056] Step S202, when the indoor environmental temperature does not reach the target temperature, obtain the running time of the air conditioner, and compare the running time with the target time;

[0057] Step S203: If the running time is less than the target time, control the air conditioner to continue running in the current state and continue to determine whether the target temperature is reached;

[0058] Step S204: If the running time is greater than the target time, it is determined that the doors and windows of the room are not closed, and a doors and windows closing reminder instruction is generated and sent accordingly.

[0059] In this embodiment, when determining whether the indoor doors and windows are closed, first determine whether the indoor environmental temperature reaches the set target temperature. When the target temperature is reached, keep the current compressor frequency and cross-flow fan speed running; when the set target temperature is not reached, obtain the running time T of the air conditioner y , and judge the running time T of the air conditioner y whether it is greater than the time T x , where the value of the time T x is set by default at the factory, for example, set to 20 min. When T y < T x , then return to continue collecting and judging; when T y > T x , it is determined that the doors and windows of the room are not closed. At this time, a doors and windows closing reminder instruction can be generated and sent out to remind the user to close the doors and windows of the room.

[0060] In a specific embodiment, as Figure 3 shown, the step S104 further includes: steps S301 to S303.

[0061] Step S301: Obtain the maximum cooling capacity or the maximum heating capacity of the air conditioner;

[0062] Step S302: Compare the target temperature with the maximum cooling capacity or the maximum heating capacity;

[0063] Step S303: When the target temperature is lower than the maximum cooling capacity or the target temperature is higher than the maximum heating capacity, reset the target temperature based on the maximum cooling capacity or the maximum heating capacity.

[0064] In order to avoid setting the target temperature too low or too high, before judging whether the indoor environmental temperature reaches the set target temperature, first obtain the maximum cooling capacity or the maximum heating capacity of the air conditioner. If the target temperature is lower than the maximum cooling capacity or the target temperature is higher than the maximum heating capacity, it means that no matter how long the air conditioner runs and at what operating parameters, the target temperature cannot be reached. Therefore, the target temperature can be reset within the temperature range between the maximum cooling capacity and the maximum heating capacity, so that the air conditioner can stably run to the target temperature, avoid energy consumption waste and equipment loss caused by unreasonable temperature setting, and achieve the effect of intelligent temperature control.

[0065] In another specific embodiment, step S104 further includes:

[0066] Collect the outdoor ambient temperature and calculate the temperature difference between the outdoor ambient temperature and the target temperature;

[0067] When the outdoor ambient temperature reaches a preset temperature threshold and / or the temperature difference reaches a preset temperature difference threshold, reset the target time according to a preset time adjustment strategy.

[0068] In addition, to ensure that the air conditioner can reach the target temperature within a reasonable time, the outdoor ambient temperature is collected, and the difference between it and the target temperature is calculated. If the outdoor ambient temperature or the temperature difference exceeds the corresponding preset threshold, after comprehensive evaluation, the target time is adjusted to ensure the balance between the air conditioner operation efficiency and comfort, and avoid unnecessary energy consumption. For example, judge whether the outdoor air temperature is greater than 35°C, and judge whether the difference between the outdoor air temperature and the air conditioner set temperature is greater than 20°C. When either of them is satisfied, the reminder time T for the unclosed doors and windows can be extended. x By real-time monitoring of the indoor and outdoor temperature difference and dynamically adjusting the operation strategy, it not only ensures environmental comfort but also meets the energy-saving requirements, taking into account the privacy and work efficiency of family life and realizing the improvement of intelligent living quality.

[0069] In one embodiment, as Figure 4 shown, step S105 includes steps S401 to S406.

[0070] Step S401: Judge whether there is a heat source within a preset heat source temperature range according to the indoor heat source information;

[0071] Step S402: If there is a heat source within the preset heat source temperature range, it is determined that there are people in the room;

[0072] Step S403: If there is no heat source within the preset heat source temperature range, it is determined that there are no people in the room, and the air conditioner is controlled to operate in a preset energy-saving mode, and then the unmanned time when there are no people in the room is obtained;

[0073] Step S404: Compare the unmanned time with the preset energy-saving time;

[0074] Step S405: If the unmanned time is less than the energy-saving time, control the air conditioner to exit the energy-saving mode and continue to control the operation of the air conditioner according to the indoor heat source information and the indoor ambient temperature;

[0075] Step S406: If the unmanned time is greater than or equal to the energy-saving time, generate a shutdown instruction and control the air conditioner to stop operating according to the shutdown instruction.

[0076] In this embodiment, the system first determines whether the indoor heat source corresponds to the human body, for example, by determining whether a heat source between 34°C and 40°C exists. This information is then used to determine whether a person is present in the room. Specifically, if a heat source within the human temperature range is detected, the presence of a person is determined; otherwise, the presence of a person is determined. If a person is detected, the air conditioner continues to operate on demand to maintain a suitable temperature. If no one is detected, energy-saving mode is activated, and the time spent away from the room is recorded and compared with a preset energy-saving time. If the time spent away from the room exceeds the preset energy-saving time, a shutdown command is automatically generated, stopping the air conditioner. This further reduces energy consumption and ensures maximum resource utilization. It also avoids the problem of the air conditioner turning on and off repeatedly due to people frequently entering and leaving the room within a short period of time. In this way, the air conditioning system not only responds to environmental changes in real time but also intelligently adjusts its operating status, improving the user experience while significantly reducing energy consumption, achieving the dual goals of efficiency and environmental friendliness in smart homes.

[0077] In actual application, when combining the unmanned time and the energy-saving time to determine whether the air conditioner needs to be shut down, when the unmanned time is greater than or equal to the energy-saving time, a prompt message of automatic shutdown due to no one is first issued to remind the user who is pretending to leave that the air conditioner will be automatically shut down. Then, it is continued to be determined whether the unmanned time reaches the preset shutdown time. If the unmanned time reaches the shutdown time, it is determined that the user is truly away from the house. At this time, the air conditioner can be controlled to shut down and stop running. If the unmanned time does not reach the shutdown time, it is determined that the user is pretending to leave the house. At this time, the air conditioner can be controlled to exit the energy-saving mode to provide a more comfortable experience for the user who is pretending to leave the house again.

[0078] Specifically, such as Figure 5 As shown, the step S402 includes steps S501 to S503.

[0079] Step S501: When there are people in the room, determine the number of people according to the heat source information, and determine whether the number of people has decreased;

[0080] Step S502: when it is determined that the number of people has not decreased, increasing the target operating parameters of the air conditioner according to a preset adjustment strategy;

[0081] Step S503: when it is determined that the number of people is reduced, the target operating parameters of the air conditioner are reduced according to a preset adjustment strategy.

[0082] When it is determined that there are people in the room, the number of people is further determined based on the heat source information, that is, it is judged whether the number of people in the room has changed. If the number of people in the room has not decreased, the target operating parameter can be appropriately increased according to the preset adjustment strategy; if it has decreased, the target operating parameter can be correspondingly decreased according to the preset adjustment strategy. Through this dynamic adjustment mechanism, the air conditioner can accurately match the actual demand, avoid over-cooling or over-heating, ensure that the indoor temperature is always in the comfortable range, effectively save energy, and improve the overall operating efficiency.
