Description

Technical Field

[0001] This invention belongs to the field of air conditioning technology, and more specifically, relates to an air conditioner and its temperature control method and system. Background Technology

[0002] In the field of air conditioning technology, especially in ducted air conditioning products, uneven indoor temperature distribution is a common problem. This is mainly because air conditioners are usually not installed in the exact center of the room, resulting in a significant temperature gradient between the area near the air outlet and the area farther away from the outlet. Most common ducted air conditioning units use a simple horizontal air outlet design and do not even have a swing function, thus lacking effective control over the air outlet angle.

[0003] Even if some products are designed with air vents that have a swing function, their control strategies are relatively simple, usually limited to fixed up-down or left-right swing patterns. This simple periodic swing does not detect or provide feedback on the actual temperature distribution in the room, so it cannot achieve targeted and precise control of the swing action, making it difficult to quickly achieve a uniform room temperature.

[0004] Furthermore, the swing motors used in the industry typically lack status feedback functionality. When the swing mechanism malfunctions due to component damage or loss, the air conditioning system itself cannot detect the fault and continues to operate without its knowledge. This not only affects the room's temperature control but also delays the user's ability to report repairs.

[0005] In existing technologies, some solutions have proposed using infrared thermal imaging devices to acquire temperature image data within a space, dividing it into isothermal zones and calculating the weighted average temperature of each zone, using this as the current indoor temperature, and then uniformly regulating and controlling the air conditioning system.

[0006] However, this method has limitations. It ultimately calculates and relies solely on an overall spatial average temperature value, failing to fully explore and utilize detailed temperature data from different regions. Specifically, it cannot identify temperature anomalies in specific local areas, nor does it use temperature differences between different regions as a basis for controlling the air sweeping mechanism. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides an air conditioner and its temperature control method and system.

[0008] The present invention adopts the following technical solution.

[0009] The first aspect of the present invention provides an air conditioning temperature control method, comprising: Start the air conditioning system, execute the self-test process of the air sweeping mechanism, and determine the current state of the air sweeping mechanism as full-function state, degraded operation state or fault shutdown state based on the self-test results; Based on the current state, enter the corresponding operating mode, including full-function operating mode, fault adaptive mode, and shutdown error reporting mode; During operation in full-function mode or fault-adaptive mode, the following intelligent temperature control cycle is executed periodically: The current temperature distribution information of the room is obtained through thermal imaging sensors; Based on the temperature distribution information, the temperature areas to be adjusted are selected, and the corresponding air supply parameters are calculated for each temperature area to be adjusted. For each temperature zone to be adjusted, the air supply parameters and the current state are combined to control the air sweeping mechanism to perform air supply actions.

[0010] Optionally, the self-inspection process of the air-sweeping mechanism includes: Start the fan, control the humidification module of the air conditioning system to generate water mist, and control the upper and lower air sweeping plates to be in the closed position; Temperature distribution information is obtained by using a thermal imaging sensor, and based on the temperature distribution information, it is determined whether there is a mist-like area in front of the air outlet that corresponds to the water mist. If it is determined that there is a mist-like area corresponding to the water mist, then the up and down air sweeping function is abnormal. If it is determined that there is no mist-like area corresponding to the water mist, the upper and lower air sweeping plates are switched to the open position, and the temperature distribution information is obtained again through the thermal imaging sensor. Based on the temperature distribution information, it is determined whether there is a mist-like area corresponding to the water mist in front of the air outlet. If the current determination indicates the existence of a mist-like area corresponding to the water mist, then the up and down air sweeping function is confirmed to be normal. If it is determined that there is no mist-like area corresponding to the water mist, then the up and down air sweeping function is abnormal and the air vent cannot be opened.

[0011] Optionally, the self-test process of the sweeping mechanism further includes testing the left and right sweeping functions, including: After confirming that the up and down air sweeping function is normal, control the left and right air sweeping vanes to perform left and right air sweeping actions; The thermal imaging sensor monitors whether the area of ​​the mist-like region corresponding to the water mist changes with the movement of the left and right air-sweeping plates; If the area of ​​the fog-like region does not change as expected, then the left and right sweeping functions are determined to be abnormal. If the area of ​​the fog-like region changes as expected, then the left and right sweeping functions are confirmed to be normal.

[0012] Optionally, if both the up-and-down sweeping function and the left-and-right sweeping function of the sweeping mechanism are determined to be normal, then the current state is determined to be a full-function state. If the up-and-down sweeping function of the sweeping mechanism is determined to be normal, and the left-and-right sweeping function is determined to be abnormal, then the current state is determined to be a degraded operation state. If the up-and-down sweeping function of the sweeping mechanism is determined to be abnormal and the air vent cannot be opened, then the current state is determined to be a fault shutdown state.

[0013] Optionally, entering the corresponding operating mode based on the current state includes: If it is in the full-function state, then it enters the full-function operation mode, which allows the sweeping mechanism to operate in the full range, including controlling the upper and lower sweeping plates and the left and right sweeping plates to sweep. If the operation is in the degraded state, it will enter the fault adaptive mode, which only allows temperature control by controlling the movement of the upper and lower air sweeping plates. If the system is in a fault shutdown state, the air conditioning system will stop operating and an error will be reported.

[0014] Optionally, the step of filtering the temperature region to be adjusted based on the temperature distribution information includes: Generate a room temperature distribution map based on the current temperature distribution information; Identify and eliminate areas of heat source interference from the temperature distribution map; The temperature distribution map after excluding the heat source interference area is divided into multiple temperature regions. The division is achieved by grouping adjacent pixels whose temperature values ​​are within a first preset temperature difference threshold into the same temperature region. The term "adjacent" means that the coordinate difference between pixels does not exceed a set step size. Determine the center point of each temperature zone, and use the temperature value of the center point as the representative temperature value of that temperature zone. The multiple temperature regions are filtered using predefined region division rules, which divide the temperature distribution map into near-field, far-field, and reference regions. The filtering process includes: The temperature region whose center point is discarded is located within the reference region; For temperature regions whose center point is located in the near or far region, calculate the average representative temperature value of these temperature regions, compare the representative temperature value of these temperature regions with the average representative temperature value, determine the region whose temperature difference does not exceed the second preset temperature difference threshold as the average temperature region, and determine the region whose temperature difference exceeds the second preset temperature difference threshold as the temperature region to be adjusted.

[0015] Optionally, calculating the corresponding air supply parameters for each of the temperature zones to be adjusted includes: For each of the temperature zones to be adjusted, a sweep angle is calculated, whereby the sweep angle is the direction of the line connecting the outlet reference point and the center point of the temperature zone to be adjusted. The sweeping residence time is calculated for each of the temperature zones to be adjusted. The initial value of the sweeping residence time is set based on the temperature difference between the representative temperature value and the average representative temperature value of the temperature zone to be adjusted.

[0016] Optionally, the dynamic adjustment logic for the sweeping residence time includes: During the execution of the intelligent temperature control, the temperature changes of each temperature zone to be adjusted are recorded. If, after the first set time period, the temperature difference between the representative temperature value and the average representative temperature value of the temperature area to be adjusted does not show a decreasing trend, then the sweeping residence time of the temperature area to be adjusted is increased. If the temperature region to be adjusted is located in the far region, it is identified as the ultra-far region; When the sweeping residence time of the temperature area to be adjusted has reached the set maximum residence time, and the maximum residence time is maintained for a second set duration, if the decrease in the temperature difference between the representative temperature value and the average representative temperature value of the temperature area to be adjusted does not reach the expected improvement threshold, the temperature area to be adjusted is marked as a control insensitive area, and sweeping residence control is not performed on the control insensitive area in subsequent intelligent temperature equalization control cycles.

[0017] A second aspect of the present invention provides an air conditioning temperature equalization control system for implementing the air conditioning temperature equalization control method described in the first aspect of the present invention, comprising: Controller, thermal imaging sensor, humidification module, fan, wired controller, and air-sweeping mechanism, among which: The controller is connected to the thermal imaging sensor, the fan, the air sweeping mechanism, the humidification module, and the wired controller, respectively, and is used for: Receive temperature distribution data from the thermal imaging sensor and user commands from the wired controller; Based on the temperature distribution data and the preset program, control commands are sent to the sweeping motor and the fan to execute the self-test and intelligent temperature equalization control cycle of the sweeping mechanism; Control the start and stop of the humidification module to cooperate with the self-test of the air-sweeping mechanism or to perform the humidification function; The thermal imaging sensor is used to learn the room's temperature distribution, generate a temperature distribution map, and send it to the controller. The humidification module is used to generate water mist according to the instructions of the controller; The fan is used to provide airflow power to the air outlet according to the instructions of the controller; The wired controller is used to receive user commands and display system status information; The sweeping mechanism includes a sweeping motor and a sweeping plate. The sweeping motor is connected to the sweeping plate and is used to drive the sweeping plate to move according to the control command of the controller. The sweeping motor includes an independently controllable upper sweeping motor, a lower sweeping motor, and left and right sweeping motors.

[0018] A third aspect of the present invention provides an air conditioner, including the air conditioner temperature equalization control system described in the second aspect of the present invention.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this invention. The described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the spirit of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this invention.

[0031] In Embodiment 1, the present invention provides an air conditioning temperature control method, such as... Figure 1 As shown, it includes: Step 1: Start the air conditioning system and execute the self-test process of the air sweeping mechanism. Based on the self-test results, determine the current status of the air sweeping mechanism as full-function status, degraded operation status, or fault shutdown status.

[0032] Preferably, the self-inspection process of the air-sweeping mechanism includes: Start the fan, control the humidification module of the air conditioning system to generate water mist, and control the upper and lower air sweeping plates to be in the closed position; Temperature distribution information is obtained by using a thermal imaging sensor, and based on the temperature distribution information, it is determined whether there is a mist-like area in front of the air outlet that corresponds to the water mist. If it is determined that there is a mist-like area corresponding to the water mist, then the up and down air sweeping function is abnormal. If it is determined that there is no mist-like area corresponding to the water mist, the upper and lower air sweeping plates are switched to the open position, and the temperature distribution information is obtained again through the thermal imaging sensor. Based on the temperature distribution information, it is determined whether there is a mist-like area corresponding to the water mist in front of the air outlet. If the current determination indicates the existence of a mist-like area corresponding to the water mist, then the up and down air sweeping function is confirmed to be normal. If it is determined that there is no mist-like area corresponding to the water mist, then the up and down air sweeping function is abnormal and the air vent cannot be opened.

[0033] It should be noted that by utilizing thermal imaging sensors and water mist detection of the up and down air sweeping function, this invention solves the problem of requiring additional sensors for fault detection of the air sweeping mechanism, and achieves low-cost and efficient fault self-diagnosis.

[0034] Preferably, the self-test process of the sweeping mechanism further includes testing the left and right sweeping functions, including: After confirming that the up and down air sweeping function is normal, control the left and right air sweeping vanes to perform left and right air sweeping actions; The thermal imaging sensor monitors whether the area of ​​the mist-like region corresponding to the water mist changes with the movement of the left and right air-sweeping plates; If the area of ​​the fog-like region does not change as expected, then the left and right sweeping functions are determined to be abnormal. If the area of ​​the fog-like region changes as expected, then the left and right sweeping functions are confirmed to be normal.

[0035] It should be noted that this invention detects the left and right sweeping function by monitoring changes in the area of ​​the water mist region, thus solving the problem of detecting left and right sweeping faults and realizing a comprehensive self-test of the sweeping function.

[0036] More preferably, the anticipated change includes: When the left and right sweeping plates reach the maximum angle on the left, the area of ​​the current foggy region increases to the left. When the left and right air-sweeping plates reach the maximum angle on the right, the area of ​​the current foggy region increases to the right.

[0037] Preferably, if both the up-and-down sweeping function and the left-and-right sweeping function of the sweeping mechanism are determined to be normal, then the current state is determined to be a full-function state. If the up-and-down sweeping function of the sweeping mechanism is determined to be normal, and the left-and-right sweeping function is determined to be abnormal, then the current state is determined to be a degraded operation state. If the up-and-down sweeping function of the sweeping mechanism is determined to be abnormal and the air vent cannot be opened, then the current state is determined to be a fault shutdown state.

[0038] It should be noted that this invention determines the system status based on the self-test results of the up-down and left-right sweeping functions, which solves the problem of unclear status judgment and realizes accurate classification and corresponding processing of system status.

[0039] Specifically, when the left and right swing function of the air swing mechanism is determined to be abnormal or the up and down swing function is determined to be abnormal and the air vent cannot be opened, the corresponding fault code will be displayed to remind the user.

[0040] Preferably, the judgment logic for determining whether there is a mist-like area corresponding to the water mist in front of the air outlet based on the temperature distribution information is as follows: by scanning the temperature distribution information obtained by the thermal imaging sensor, the logic detects whether there are areas of discontinuity in temperature data caused by water mist, including: The pixel temperature values ​​are analyzed row by row or column by column according to the preset scanning direction. When the temperature change between adjacent pixels exceeds the set temperature difference threshold, it is recorded as a sudden change. If the cumulative number of mutations in a single row or column of data reaches or exceeds the set threshold for the number of changes, it is determined that there are multiple mutations in that row or column of data. When the number of rows or columns with multiple mutations exceeds the set threshold for the number of rows or columns, the foggy region is determined to exist. The preset scanning direction, the temperature difference threshold, the number of changes threshold, and the number of rows or columns threshold can all be adjusted and configured according to the actual application scenario.

[0041] For example, the parameters involved in the judgment logic are configured as follows: The set temperature difference threshold is 3℃; The set threshold for the number of changes is 3 times; The set threshold for the number of rows or columns is 5.

[0042] Step 2: Based on the current state, enter the corresponding operating mode, including full-function operating mode, fault adaptive mode, and shutdown error reporting mode.

[0043] Preferably, entering the corresponding operating mode based on the current state includes: If it is in the full-function state, then it enters the full-function operation mode, which allows the sweeping mechanism to operate in the full range, including controlling the upper and lower sweeping plates and the left and right sweeping plates to sweep. If the operation is in the degraded state, it will enter the fault adaptive mode, which only allows temperature control by controlling the movement of the upper and lower air sweeping plates. If the system is in a fault shutdown state, the air conditioning system will stop operating and an error will be reported.

[0044] It should be noted that this invention enters full-function operation, fault adaptive operation, or shutdown error reporting mode according to the system status, which solves the problem of low system operating efficiency under abnormal conditions and realizes optimized operation and safe fault handling.

[0045] Step 3: During the operation of full-function mode or fault adaptive mode, the following intelligent temperature control cycle is executed periodically: The current temperature distribution information of the room is obtained through thermal imaging sensors; Based on the temperature distribution information, the temperature areas to be adjusted are selected, and the corresponding air supply parameters are calculated for each temperature area to be adjusted. For each temperature zone to be adjusted, the air supply parameters and the current state are combined to control the air sweeping mechanism to perform air supply actions.

[0046] It should be noted that this invention solves the problem that the air conditioning system cannot operate adaptively when the air swing mechanism is abnormal by starting a self-test and entering the operation mode based on the status, and periodically executing the intelligent temperature control cycle, thus realizing precise temperature control based on the room temperature distribution.

[0047] Preferably, the step of filtering the temperature region to be adjusted based on the temperature distribution information includes: Generate a room temperature distribution map based on the current temperature distribution information; Identify and eliminate areas of heat source interference from the temperature distribution map; The temperature distribution map after excluding the heat source interference area is divided into multiple temperature regions. The division is achieved by grouping adjacent pixels whose temperature values ​​are within a first preset temperature difference threshold into the same temperature region. Here, "adjacent" means that the coordinate difference between pixels does not exceed a set step size. Determine the center point of each temperature zone, and use the temperature value of the center point as the representative temperature value of that temperature zone. The multiple temperature regions are filtered using predefined region division rules, which divide the temperature distribution map into near-field, far-field, and reference regions. The filtering process includes: The temperature region whose center point is discarded is located within the reference region; For temperature regions whose center point is located in the near or far region, calculate the average representative temperature value of these temperature regions, compare the representative temperature value of these temperature regions with the average representative temperature value, determine the region whose temperature difference does not exceed the second preset temperature difference threshold as the average temperature region, and determine the region whose temperature difference exceeds the second preset temperature difference threshold as the temperature region to be adjusted.

[0048] It should be noted that this invention solves the problem of inaccurate temperature distribution analysis by generating a temperature distribution map, eliminating heat source interference, and dividing temperature regions to screen the regions to be adjusted, thus achieving accurate identification of the regions that need temperature adjustment.

[0049] For example, the parameters involved in the region division and filtering are configured as follows: The first preset temperature difference threshold used to group adjacent pixels into the same temperature region is 1℃; the meaning of this threshold is that if the temperature difference between two adjacent pixels is not greater than 1℃, they can be grouped into the same temperature region. The second preset temperature difference threshold used to identify the temperature range to be adjusted is 3°C to 5°C.

[0050] For example, identifying and eliminating heat source interference areas from the temperature distribution map includes: Continuous image areas with significantly higher local temperatures than the surrounding environment are identified as heat sources. Common indoor heat sources include people, windows, and electrical appliances. Since these heat sources continuously release heat, the temperature data of their areas can interfere with the overall room temperature control. Therefore, in the subsequent temperature zone division and air supply parameter calculation, all identified heat source areas will be automatically excluded, and only the remaining effective areas will be analyzed and controlled.

[0051] For example, the region division rules include: The lower two-thirds of the temperature distribution map is considered the near zone. The upper quarter to the upper third of the temperature distribution map is considered the far zone. The remaining upper 1 / 4 area is considered as the reference area.

[0052] Preferably, calculating the corresponding air supply parameters for each of the temperature zones to be adjusted includes: For each of the temperature zones to be adjusted, a sweep angle is calculated, whereby the sweep angle is the direction of the line connecting the outlet reference point and the center point of the temperature zone to be adjusted. The sweeping residence time is calculated for each of the temperature zones to be adjusted. The initial value of the sweeping residence time is set based on the temperature difference between the representative temperature value and the average representative temperature value of the temperature zone to be adjusted.

[0053] It should be noted that this invention calculates the sweep angle and residence time for each area to be adjusted, which solves the problem of inaccurate air supply parameter settings and achieves targeted air supply control.

[0054] For example, the initial value of the sweeping dwell time is set to 1 second.

[0055] More preferably, the sweeping residence time can be dynamically adjusted, including: During the execution of the intelligent temperature control, the temperature changes of each temperature zone to be adjusted are recorded. If, after a first set time period, the temperature difference between the representative temperature value of the temperature area to be adjusted and the average representative temperature value does not show a decreasing trend, then the sweeping residence time of the temperature area to be adjusted is increased. If the temperature region to be adjusted is located in the far region, it is further identified as the ultra-far region; When the sweeping residence time of the temperature area to be adjusted has reached the set maximum residence time, and the maximum residence time is maintained for a second set duration, if the decrease in the temperature difference between the representative temperature value and the average representative temperature value of the temperature area to be adjusted does not reach the expected improvement threshold, the temperature area to be adjusted is marked as a control insensitive area, and sweeping residence control will no longer be performed on the temperature area to be adjusted in subsequent intelligent temperature equalization control cycles.

[0056] For example, the first set duration is 10 minutes; Each additional sweeping dwell time for the temperature zone to be adjusted is 1 second; The maximum dwell time is set to 3 seconds; The second set duration is 20 minutes; The expected improvement threshold is 2°C.

[0057] It should be noted that this invention solves the problem of poor adaptability of the air supply strategy by dynamically adjusting the air sweeping residence time and marking the control insensitive area, thus realizing intelligent optimization of air supply and energy saving.

[0058] More preferably, the air supply parameters further include the air supply mode: If the center point of the temperature-to-be-adjusted area is not located in the ultra-far zone, the conventional air supply mode shall be used. If the center point of the temperature-to-be-adjusted area is located in the ultra-far zone, the far-zone air supply mode is adopted.

[0059] More preferably, the air supply mode further includes: the average temperature zone is swept left and right without stopping, while the left and right sweeping angle of the temperature zone to be adjusted is calculated and stopped.

[0060] For example, such as Figure 4 As shown, for the far-area air supply mode, air can be supplied to the ultra-far area by controlling the upper and lower air-sweeping vanes to close the air outlets and reduce the air outlet area. To avoid rapid changes in the air-sweeping vanes, the air outlet angle control path will form a circle depending on the distance of the area.

[0061] Preferably, the air conditioning temperature control method further includes re-triggering the self-test process of the air swing mechanism in response to meeting any of the following conditions: The system runs continuously for the preset period of time; Received a self-test command from the user via the terminal device.

[0062] In Embodiment 2, this invention provides an air conditioning temperature equalization control system for implementing the air conditioning temperature equalization control method described in Embodiment 1, such as... Figure 2 , Figure 3 As shown, it includes: MCU, thermal imaging sensor, humidification module, fan, wired controller, and air-sweeping mechanism, among which: The MCU is connected to the thermal imaging sensor, the fan, the air sweeping mechanism, the humidification module, and the wired controller, respectively, and is used for: Receive temperature distribution data from the thermal imaging sensor and user commands from the wired controller; Based on the temperature distribution data and the preset program, control commands are sent to the sweeping motor and the fan to execute the self-test and intelligent temperature equalization control cycle of the sweeping mechanism; Control the start and stop of the humidification module to cooperate with the self-test of the air-sweeping mechanism or to perform the humidification function; The thermal imaging sensor is used to learn the room's temperature distribution, generate a temperature distribution map, and send it to the MCU. The humidification module is used to generate water mist according to the instructions of the MCU; The fan is used to provide airflow power to the air outlet according to the instructions of the MCU; The wired controller is used to receive user commands and display system status information; The air-sweeping mechanism includes an air-sweeping motor and an air-sweeping plate. The air-sweeping motor is connected to the air-sweeping plate and is used to drive the air-sweeping plate to move according to the control instructions of the MCU. The air-sweeping motor includes an independently controllable upper air-sweeping motor, a lower air-sweeping motor, and left and right air-sweeping motors.

[0063] It should be noted that this invention constructs a uniform temperature control system using components such as an MCU and a thermal imaging sensor, thus solving the problem of hardware support for the method implementation and achieving efficient and reliable uniform temperature control.

[0064] Specifically, the thermal imaging sensor can only detect the radiation temperature of an object and cannot detect the air temperature. Therefore, when the humidification module is activated, the thermal imaging sensor can indirectly detect the airflow by detecting the temperature of the water mist.

[0065] Specifically, the humidification module is the humidification function module of the air conditioning unit, located in the lower center of the air vent. When activated, it generates water mist upwards, and when the fan starts, the water mist is blown out, increasing the room humidity. The humidification module is an ultrasonic humidification module.

[0066] Specifically, the fan is used to provide power for the air outlet. It is located behind the air outlet and generally adopts a centrifugal structure. In the technical implementation of this embodiment, it is basically in the on state. By default, after the unit is started, the fan continuously provides power for air outlet.

[0067] Specifically, the upper and lower sweeping fan motor can move the upper and lower sweeping plates to close the air outlet in the middle, thereby reducing the air outlet area, increasing the air outlet speed, and thus increasing the air delivery distance.

[0068] In Embodiment 3, the present invention provides an air conditioner, including the air conditioner temperature equalization control system described in Embodiment 2.

[0069] It should be noted that this invention solves the problem of poor temperature uniformity in traditional air conditioners by integrating a temperature uniformity control system into the air conditioner, and provides an intelligent temperature uniformity air conditioner product.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of the present invention.

The air conditioning temperature control method according to claim 1, characterized in that: The self-test process for the sweeping mechanism also includes testing the left and right sweeping functions, including: After confirming that the up and down air sweeping function is normal, control the left and right air sweeping vanes to perform left and right air sweeping actions; The thermal imaging sensor monitors whether the area of ​​the mist-like region corresponding to the water mist changes with the movement of the left and right air-sweeping plates; If the area of ​​the fog-like region does not change as expected, then the left and right sweeping functions are determined to be abnormal. If the area of ​​the fog-like region changes as expected, then the left and right sweeping functions are confirmed to be normal.

3. The air conditioning temperature control method according to claim 2, characterized in that: If both the up-and-down sweeping function and the left-and-right sweeping function of the sweeping mechanism are determined to be normal, then the current state is determined to be a full-function state. If the up-and-down sweeping function of the sweeping mechanism is determined to be normal, and the left-and-right sweeping function is determined to be abnormal, then the current state is determined to be a degraded operation state. If the up-and-down sweeping function of the sweeping mechanism is determined to be abnormal and the air vent cannot be opened, then the current state is determined to be a fault shutdown state.

4. The air conditioning temperature control method according to claim 1, characterized in that: The step of entering the corresponding operating mode based on the current state includes: If it is in the full-function state, then it enters the full-function operation mode, which allows the sweeping mechanism to operate in the full range, including controlling the upper and lower sweeping plates and the left and right sweeping plates to sweep. If the operation is in the degraded state, it will enter the fault adaptive mode, which only allows temperature control by controlling the movement of the upper and lower air sweeping plates. If the system is in a fault shutdown state, the air conditioning system will stop operating and an error will be reported.

The division is achieved by grouping adjacent pixels whose temperature values ​​are within a first preset temperature difference threshold into the same temperature region. The term "adjacent" means that the coordinate difference between pixels does not exceed a set step size. Determine the center point of each temperature zone, and use the temperature value of the center point as the representative temperature value of that temperature zone. The multiple temperature regions are filtered using predefined region division rules, which divide the temperature distribution map into near-field, far-field, and reference regions. The filtering process includes: The temperature region whose center point is discarded is located within the reference region; For temperature regions whose center point is located in the near or far region, calculate the average representative temperature value of these temperature regions, compare the representative temperature value of these temperature regions with the average representative temperature value, determine the region whose temperature difference does not exceed the second preset temperature difference threshold as the average temperature region, and determine the region whose temperature difference exceeds the second preset temperature difference threshold as the temperature region to be adjusted.

The sweeping residence time is calculated for each of the temperature zones to be adjusted. The initial value of the sweeping residence time is set based on the temperature difference between the representative temperature value and the average representative temperature value of the temperature zone to be adjusted.

7. The air conditioning temperature control method according to claim 6, characterized in that: The dynamic adjustment logic for the sweeping residence time includes: During the execution of the intelligent temperature control, the temperature changes of each temperature zone to be adjusted are recorded. If, after the first set time period, the temperature difference between the representative temperature value and the average representative temperature value of the temperature area to be adjusted does not show a decreasing trend, then the sweeping residence time of the temperature area to be adjusted is increased. If the temperature region to be adjusted is located in the far region, it is identified as the ultra-far region; When the sweeping residence time of the temperature area to be adjusted has reached the set maximum residence time, and the maximum residence time is maintained for a second set duration, if the decrease in the temperature difference between the representative temperature value and the average representative temperature value of the temperature area to be adjusted does not reach the expected improvement threshold, the temperature area to be adjusted is marked as a control insensitive area, and sweeping residence control is not performed on the control insensitive area in subsequent intelligent temperature equalization control cycles.
