Description

Technical Field

[0001] This application relates to the technical field of intelligent building control, specifically to a control method, system, electronic device, and storage medium for intelligent building central air conditioning. Background Technology

[0002] With the development of technology and the improvement of people's living standards, the intelligent control and management of central air conditioning systems, as an important component of building environmental regulation, are becoming increasingly important. Through reasonable control methods, precise adjustment of environmental parameters such as temperature and humidity within buildings can be achieved, improving user comfort while reducing energy consumption.

[0003] Most existing central air conditioning control methods rely on fixed schedules or preset temperature thresholds, lacking flexibility to adapt to actual conditions. For example, some control methods may only open or close air vents during specific time periods, failing to dynamically adjust the vents' opening and closing status based on changes in the number of people in the building. This control method not only leads to energy waste but may also fail to provide sufficient cooling or heating when there are many people, affecting occupants' comfort. Furthermore, regulating central air conditioning through temperature thresholds requires temperature sensors to operate in real time, and buildings often have numerous temperature sensors; keeping these sensors constantly active generates significant energy consumption.

[0004] Therefore, how to achieve intelligent control of building central air conditioning systems, automatically adjust the opening and closing of air outlets and temperature in real time according to the flow of people, and reduce overall energy consumption has become a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] This application provides a control method, system, electronic device, and storage medium for intelligent building central air conditioning, which can automatically adjust the opening and closing of the air outlet and the temperature in real time according to the flow of people, and reduce the overall energy consumption.

[0006] The first aspect of this application provides a control method for an intelligent building central air conditioning system, applied to a central air conditioning control platform, the control method comprising:

[0007] Acquire a first image from the first camera at a first preset time interval, and determine whether the number of people in the first image exceeds a first number threshold.

[0008] When the number of people in the first image exceeds the first number threshold, the first code of the first camera is obtained, and the first air outlet group corresponding to the first camera is determined according to the first code based on the first preset correspondence.

[0009] Based on the second preset correspondence, the target temperature sensor group corresponding to the first camera is determined according to the encoding. The first temperature value of the first sub-temperature sensor in the target temperature sensor group is obtained. The opening and closing of the corresponding air outlet in the first air outlet group is controlled according to the first temperature value. The first sub-temperature sensor is any one of the temperature sensors in the target temperature sensor group.

[0010] By adopting the above technical solution, the system can acquire the first image from the first camera at a first preset time interval and determine in real time whether the number of people in the image exceeds a first threshold. This real-time capability ensures that the system can quickly respond to changes in the number of people, thereby adjusting the airflow status of the central air conditioning system. When the camera detects that the number of people exceeds the threshold, the system can automatically acquire the camera's code and determine the corresponding air outlet group and target temperature sensor group based on a preset correspondence. This process requires no manual intervention, achieving intelligent temperature management. Based on the first temperature value of the first sub-temperature sensor in the target temperature sensor group, the central air conditioning control platform can control the opening and closing of the corresponding air outlet in the first air outlet group. This means that the central air conditioning control platform can perform personalized temperature adjustment according to the actual temperature of each area, ensuring the comfort of each area. By precisely controlling the opening and closing of each air outlet, unnecessary energy consumption can be avoided, especially in areas with fewer people, where some air outlets can be closed to save energy. This control method, based on a preset correspondence, can be easily extended to multiple cameras and air outlet groups to achieve intelligent temperature management of the entire building. Because it can adjust the airflow status in real time according to the distribution of people and temperature conditions, it can provide users with a more comfortable and energy-saving indoor environment, improving the user experience.

[0011] Optionally, the control method includes:

[0012] Each floor of the building is divided into zones, and each camera is assigned a unique first code, which includes the floor number, zone number, and first sequence number.

[0013] Each air outlet is assigned a unique second code, which includes the floor number, area number, first group number, and second sequence number.

[0014] Each temperature sensor is assigned a unique third code, which includes the floor number, area number, second group number, and third sequence number;

[0015] Based on the positional relationship, a first preset correspondence is established between the first code and the second code, a second preset correspondence is established between the first code and the third code, and a third preset correspondence is established between the second code and the third code.

[0016] By adopting the above technical solution, each floor of the building is divided into zones, and cameras, air vents, and temperature sensors are assigned unique codes. This allows the central air conditioning control platform to accurately locate and manage each device. This ensures that when the central air conditioning control platform receives specific instructions or data, it can accurately identify and act on the target device. Multiple preset correspondences allow the central air conditioning control platform to intelligently identify the corresponding air vents and temperature sensors based on camera image data, thereby achieving temperature control in that area. This intelligent operation greatly improves the response speed and accuracy of the central air conditioning control platform. The establishment of codes and correspondences is based on a standardized model, which allows the central air conditioning control platform to be easily expanded to more floors, zones, and devices. When new cameras, air vents, or temperature sensors need to be added, simply assign them new codes according to the same coding rules and update the relevant information in the correspondence. Because each device has a unique code, when the central air conditioning control platform malfunctions or has a problem, the specific device can be quickly located for targeted troubleshooting and repair. This greatly reduces the time and difficulty of troubleshooting. By establishing correspondences, the central air conditioning control platform can integrate data from different devices to form a complete building environment dataset. This data can be used for further analysis and mining to optimize building temperature control strategies, improve energy efficiency, and enhance user comfort. Since the coding and correspondences are based on location relationships, the central air conditioning control platform can flexibly adjust the layout and configuration of devices. For example, when the number of devices in a certain area changes, only the correspondences need to be updated, without requiring large-scale modifications to the entire central air conditioning control platform.

[0017] Optionally, controlling the opening and closing of the corresponding air outlet in the first air outlet group according to the first temperature value includes:

[0018] The target air outlet group corresponding to the first sub-temperature sensor is determined according to the third preset correspondence.

[0019] When the first temperature value is greater than the first temperature threshold, the opening degree of the air outlet in the target air outlet group is increased or the number of air outlets opened in the target air outlet group is increased.

[0020] When the first temperature value is less than the second temperature threshold, the opening degree of the air outlet in the target air outlet group is reduced or the number of air outlets opened in the target air outlet group is reduced, and the second temperature threshold is less than the first temperature threshold.

[0021] By adopting the above technical solution, the opening degree or number of air outlets in the target air outlet group can be precisely controlled based on the real-time temperature value (i.e., the first temperature value) of the first sub-temperature sensor. This precise temperature regulation ensures rapid response and accurate control of indoor temperature. When the indoor temperature is high (i.e., the first temperature value is greater than the first temperature threshold), the central air conditioning control platform accelerates the cooling speed by increasing the opening degree of the air outlets or increasing the number of open air outlets. Conversely, when the indoor temperature is low (i.e., the first temperature value is less than the second temperature threshold), the central air conditioning control platform reduces the opening degree of the air outlets or reduces the number of open air outlets to reduce energy consumption. This method of adjusting the air outlet status according to actual needs effectively improves the energy efficiency of the central air conditioning system. By adjusting the air outlet status in real time, the central air conditioning control platform can ensure that the indoor temperature is always maintained within a comfortable range. This not only improves the comfort of indoor occupants but also helps reduce discomfort or health problems caused by excessive temperature differences. By intelligently adjusting the air outlet status, the central air conditioning control platform can reduce equipment wear and failure rate caused by frequent opening and closing. This helps reduce equipment maintenance costs and extend equipment lifespan. This control method automatically adjusts based on preset correspondences and temperature thresholds, requiring no manual intervention. This intelligent management approach not only improves management efficiency but also reduces management costs. Because the control method is based on standardized coding and correspondences, it can be easily extended to other areas or devices. When adding new cameras, air vents, or temperature sensors, only the correspondences need to be updated.

[0022] Optionally, when the first temperature value is greater than the first temperature threshold, increasing the opening degree of the air outlets in the target air outlet group or increasing the number of open air outlets in the target air outlet group includes:

[0023] When the first temperature value is greater than the first temperature threshold, the first opening of the air outlet or the first number of air outlets is increased based on the difference between the first temperature value and the first temperature threshold. The second temperature value of the first sub-temperature sensor in the target temperature sensor group is obtained at a second preset time interval, where the second preset time is less than the first preset time.

[0024] When the second temperature value is greater than the first temperature threshold, all air outlets in the target air outlet group are opened and the opening degree of the air outlets is set to the first target opening degree.

[0025] By adopting the above technical solution, when the first temperature value exceeds the first temperature threshold, the central air conditioning control platform determines the specific value of increasing the air outlet opening or increasing the number of open air outlets based on the magnitude of the temperature difference. This adaptive adjustment strategy based on temperature difference enables the system to respond more accurately to increases in indoor temperature, thereby reaching the set temperature range more quickly. After adjusting the air outlets, the central air conditioning control platform will acquire the second temperature value of the first sub-temperature sensor in the target temperature sensor group again within a short second preset time. This ensures that the system can continuously monitor changes in indoor temperature and further adjust the state of the air outlets based on the new temperature value. If the second measured temperature value is still higher than the first temperature threshold, the central air conditioning control platform will take more aggressive adjustment measures, namely, opening all air outlets in the target air outlet group and setting the opening degree to the first target opening degree. This rapid response ensures that, in extreme cases, the system can quickly reduce the indoor temperature and prevent further temperature increases. Although the central air conditioning control platform will take more aggressive adjustment measures when necessary, overall, this adaptive adjustment strategy based on temperature difference can avoid unnecessary energy consumption. When the temperature approaches the set range, the central air conditioning control platform only fine-tunes the state of the air outlets, rather than opening all outlets at once, thus improving energy efficiency. Through precise temperature response and rapid adjustment, the central air conditioning control platform ensures that the indoor temperature is consistently maintained within a comfortable range. This not only improves the comfort of occupants but also helps reduce discomfort or health problems caused by excessive temperature differences, thereby enhancing the user experience. The entire adjustment process requires no manual intervention and is executed automatically based on preset rules and algorithms. This intelligent management approach not only improves management efficiency but also reduces management costs.

[0026] Optionally, the control method further includes:

[0027] When all the first temperature values ​​in the target temperature sensor group are greater than the first temperature threshold, all the air outlets in the first air outlet group are opened, and the second temperature value of the first sub-temperature sensor in the target temperature sensor group is obtained at a third preset time interval, wherein the third preset time is less than the first preset time.

[0028] When all the second temperature values ​​in the target temperature sensor group are greater than the first temperature threshold, it is determined whether all the air outlets in the second air outlet group are open. The second air outlet group is the air outlet group corresponding to the second camera. The second camera refers to the camera with the first serial number adjacent to the first camera.

[0029] When all the air outlets in the second air outlet group are open, the air outlet temperature of the central air conditioning is reduced.

[0030] By adopting the above technical solution, when all the first temperature values ​​in the target temperature sensor group exceed the first temperature threshold, the central air conditioning control platform will immediately open all the air outlets in the first air outlet group to achieve maximum cooling efficiency. This rapid response and comprehensive cooling strategy ensures that the indoor temperature can be controlled in a short time, improving the system's adjustment speed. After fully opening the air outlets, the central air conditioning control platform will re-acquire the second temperature values ​​of the first sub-temperature sensors in the target temperature sensor group at a third preset time interval. This continuous monitoring strategy allows the central air conditioning control platform to continuously evaluate the cooling effect and perform further operations based on the new temperature values. If, after continuous monitoring, all the second temperature values ​​in the target temperature sensor group still exceed the first temperature threshold, the central air conditioning control platform will further determine the status of the second air outlet group corresponding to the second camera adjacent to the first camera. This multi-regional coordinated adjustment strategy takes into account the mutual influence between different regions, helping to achieve more balanced and effective temperature control. When all the air outlets in the second air outlet group are open, the central air conditioning control platform will further reduce the central air conditioning outlet temperature. This intelligent judgment and automatic adjustment strategy demonstrates the system's level of intelligence, enabling it to make reasonable decisions based on actual conditions to achieve better cooling effects. Through multi-zone coordinated adjustment and intelligent judgment, the central air conditioning control platform can avoid unnecessary energy consumption and improve energy efficiency. Simultaneously, this adjustment method based on temperature distribution and regional coordination also helps to achieve a more balanced and comfortable indoor temperature distribution. Through rapid response, comprehensive cooling, continuous monitoring, and intelligent adjustment, the central air conditioning control platform can ensure that the indoor temperature is always maintained within a comfortable and stable range. This not only improves the comfort of indoor occupants but also helps reduce discomfort caused by temperature fluctuations, thereby enhancing the user experience.

[0031] Optionally, the control method further includes:

[0032] A second image is acquired from a third camera at a preset location. Facial recognition is performed on the second image, and the recognition result is matched with a preset database to determine the work destination of the target person in the second image. The work destination includes the work floor and work area. The preset database is used to store the correspondence between the target person and the work destination.

[0033] Determine whether the target person is the first person matched with the work destination within the current period;

[0034] When the target person is the first person matched with the work destination in the current cycle, open the first-level air outlet of the work destination;

[0035] If the target person is not the first person matched to the work destination in the current period, increment the current number of people in the work destination by one, and determine whether the current number of people is greater than the second number threshold.

[0036] When the current number of people exceeds the second number threshold, open the second-level air outlet of the work destination.

[0037] By employing the aforementioned technical solution and utilizing facial recognition technology, the system can identify the identity of specific individuals and determine their work destination based on information in a pre-set database. This provides the system with the ability to offer personalized services to different individuals. Depending on whether the target person is the first to arrive at their work destination within the current period, the system can intelligently adjust the air vents. If the target person is the first to arrive, the system can open only the first-level air vents, gradually opening the second-level vents as more people arrive, thus achieving energy savings. The system can count the current number of people at each work destination in real time and intelligently adjust the air vents based on a threshold number. This helps ensure comfort in each area while avoiding unnecessary energy waste. Through the combination of camera and facial recognition technology, the system can respond to changes in personnel in real time and quickly adjust the air vents according to the actual situation, improving the system's responsiveness and adaptability.

[0038] Optionally, the control method further includes:

[0039] Determine if the current brightness of the target area is less than the brightness threshold;

[0040] When the current brightness of the target area is less than the brightness threshold, the third image of the target area is obtained by the fourth camera, and it is determined whether the number of people in the third image exceeds the third number threshold, wherein the third number threshold is less than the first number threshold.

[0041] When the number of people in the third image exceeds the third number threshold, determine the number of people in the third image who are in a preset pose and the total number of people, calculate the ratio of the number of people to the total number of people, and determine whether the ratio is less than the ratio threshold.

[0042] When the ratio is less than the ratio threshold, reduce the number of air outlets or reduce the opening of the air outlets.

[0043] By adopting the above technical solution, when the system detects that the current brightness of the target area is less than the brightness threshold, it will automatically determine that this may be due to lights being turned off or curtains being closed. In this scenario, the system will further determine whether it is lunchtime based on the number of people and their posture. If there are few people in the area or most people are not working (such as during lunchtime), the system will reduce the number or opening of the air vents, thereby reducing energy consumption. By comprehensively judging information such as brightness, number of people, and posture, the system can adjust the indoor environment in a timely manner after lights are turned off or curtains are closed, ensuring that people can remain comfortable even when resting or in a low-activity state. This helps improve employee work efficiency and satisfaction. By intelligently judging the situation of lights being turned off or curtains being closed, the system can more accurately understand the needs and intentions of employees. In these special cases, the system will take more humane measures to ensure the comfort and well-being of employees. The entire control process requires no manual intervention; the system can automatically judge the situation of lights being turned off or curtains being closed and intelligently adjust the state of the air vents according to the actual situation. This intelligent and automated management method reduces management costs and improves management efficiency. The system can continuously learn and optimize its judgment logic and adjustment strategies. By collecting and analyzing historical data, the system can better understand the patterns and needs of people's activities after the lights or curtains are turned off, thereby providing more accurate and personalized environmental control services.

[0044] A second aspect of this application provides a control system for an intelligent building central air conditioning system, comprising a judgment module, an encoding module, and an execution module, wherein:

[0045] The judgment module is configured to acquire a first image from the first camera at a first preset time interval and determine whether the number of people in the first image exceeds a first number threshold.

[0046] The encoding module is configured to acquire the first code of the first camera when the number of people in the first image exceeds the first number threshold, and determine the first air outlet group corresponding to the first camera based on the first code according to the first preset correspondence relationship.

[0047] The execution module is configured to determine the target temperature sensor group corresponding to the first camera based on the second preset correspondence according to the code, obtain the first temperature value of the first sub-temperature sensor in the target temperature sensor group, and control the opening and closing of the corresponding air outlet in the first air outlet group according to the first temperature value. The first sub-temperature sensor is any one of the temperature sensors in the target temperature sensor group.

[0048] A third aspect of this application provides an electronic device including a processor, a memory, a user interface, and a network interface, wherein the memory is used to store instructions, the user interface and the network interface are both used to communicate with other devices, and the processor is used to execute the instructions stored in the memory to cause the electronic device to perform the method as described in any of the foregoing.

[0049] A fourth aspect of this application provides a computer-readable storage medium storing instructions that, when executed, perform the method described in any of the preceding descriptions.

[0050] In summary, one or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0051] 1. By acquiring the first image from the first camera at preset time intervals and determining whether the number of people in the image exceeds a first threshold, this method ensures the system's real-time response to changes in the number of people indoors. Once the number exceeds the threshold, the central air conditioning control platform can react quickly and adjust the status of the corresponding air outlets;

[0052] 2. Based on the encoding of the first camera, the corresponding first air outlet group is determined through a first preset correspondence, which enables precise control of a specific area. The central air conditioning control platform can accurately adjust the air outlet status in densely populated areas, thereby providing a more comfortable indoor environment;

[0053] 3. Based on the second preset correspondence, determine the target temperature sensor group and obtain the first temperature value of the first sub-temperature sensor. This step enables the central air conditioning control platform to sense the real-time temperature of a specific area and intelligently adjust the state of the air outlet according to the temperature value to ensure that the indoor temperature is within a comfortable range;

[0054] 4. Temperature sensor values ​​are only acquired when the number of people exceeds a threshold, thus avoiding the huge energy consumption caused by the real-time activation of the temperature sensor. Furthermore, when the temperature deviates from the normal range, the ambient temperature of the target area is adjusted by regulating the number and opening degree of the air vents. This intelligent adjustment method based on the number of people and temperature helps to achieve energy-saving effects. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0061] In the description of the embodiments of this application, the words "for example" or "for instance" are used to indicate examples, illustrations, or explanations.

Rather, the use of the words "for example" or "for instance" is intended to present the relevant concepts in a specific manner.

[0062] In the description of the embodiments of this application, the term "multiple" means two or more. For example, multiple systems means two or more systems, and multiple screen terminals means two or more screen terminals. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. The terms "comprising," "including," "having," and variations thereof all mean "including but not limited to," unless otherwise specifically emphasized.

[0063] This embodiment discloses a control method for intelligent building central air conditioning, applied to a central air conditioning control platform. Figure 1 This is a flowchart illustrating the control method for intelligent building central air conditioning disclosed in an embodiment of this application, as shown below. Figure 1 As shown, the control method includes the following steps:

[0064] S110. Acquire a first image from the first camera at a first preset time interval, and determine whether the number of people in the first image exceeds a first number threshold.

[0065] The first preset time interval is a time interval set based on actual needs and the processing capacity of the central air conditioning control platform. This time interval can be fixed, such as 5 minutes or 10 minutes, or it can be dynamically adjusted based on factors such as changes in pedestrian flow and seasonal variations within the building. For example, the time interval can be increased when pedestrian flow is relatively low. Multiple cameras are installed in the building. The first camera is any one of the cameras in the building. The central air conditioning control platform, through a network connection established with the first camera, periodically sends instructions to the first camera, requesting it to capture and transmit current image data. Upon receiving the instruction, the first camera immediately takes a picture of the current scene and sends this picture as a digital image to the central air conditioning control platform. After receiving the image data, the central air conditioning control platform saves it as the first image from the first camera. The first number threshold is a value set based on the actual usage and needs of the building. It represents the critical value at which the central air conditioning control platform considers that there are too many people in a certain area, requiring adjustment of the air conditioning operation. This threshold can be customized according to different areas and time periods to better meet actual needs. After receiving the first image, the central air conditioning control platform uses image processing and analysis technology to process and analyze the image. By applying computer vision algorithms, the central air conditioning control platform can automatically identify human silhouettes in images and count the number of people in the images. This process can utilize technologies such as machine learning and deep learning to improve the accuracy and efficiency of recognition. After counting the number of people in the first image, the central air conditioning control platform compares it with a preset first number threshold. If the number exceeds the first number threshold, the central air conditioning control platform considers the area to be overcrowded and may need to take appropriate measures to adjust the air conditioning operation; if the number does not exceed the first number threshold, the central air conditioning control platform continues to maintain the current air conditioning operation and continues to acquire the next image for monitoring at regular intervals.

[0066] In some embodiments, the control method includes:

[0067] Each floor of the building is divided into zones, and each camera is assigned a unique first code, which includes the floor number, zone number, and first sequence number.

[0068] Each air outlet is assigned a unique second code, which includes the floor number, area number, first group number, and second sequence number.

[0069] Each temperature sensor is assigned a unique third code, which includes the floor number, area number, second group number, and third sequence number;

[0070] Based on the positional relationship, a first preset correspondence is established between the first code and the second code, a second preset correspondence is established between the first code and the third code, and a third preset correspondence is established between the second code and the third code.

[0071] To more effectively monitor and control temperature, each floor is divided into zones. This division can be based on the floor's function, structure, or actual needs. For example, a floor may include multiple different areas such as offices, rest areas, and meeting rooms. Floor plans or CAD drawings are used to determine the boundaries of each zone. Each zone is assigned a unique zone number for easy management and identification.

[0072] To ensure accurate identification and management of each camera, a unique first code needs to be assigned to each camera. This first code contains the camera's location information, such as floor number and area number, as well as a first serial number used to distinguish different cameras within the same area. Based on the location and area information of the first camera, a first code containing the floor number, area number, and first serial number is generated. For example, the first code could be S (camera type number) 10 (floor number) A (area number) 01 (first serial number). Similarly, to accurately control the airflow and temperature of each air outlet, a unique second code needs to be assigned to each air outlet. The second code not only contains the air outlet's location information (floor number, area number), but also the first group number to which the air outlet belongs (which may refer to a group of air outlets that are geographically close or functionally similar) and a second serial number (used to distinguish different air outlets within the same group). Based on the location and group information of the air outlet, a second code containing the floor number, area number, first group number, and second serial number is generated. For example, the second code could be C (outlet type number) 05 (floor number) B (area number) 01 (first group number) 04 (second serial number). Temperature sensors are used to monitor the temperature in various areas of the building in real time. To accurately acquire and identify temperature data, each temperature sensor needs to be assigned a unique third code. The third code also includes the sensor's location information (floor number, area number), its second group number (which may refer to a group of temperature sensors that are close together or use the same temperature control logic), and a third serial number (used to distinguish different temperature sensors within the same group). Based on the location and group information of the temperature sensor, a third code containing the floor number, area number, second group number, and third serial number is generated. For example, the third code could be W (temperature sensor type number) 08 (floor number) D (area number) 06 (second group number) 05 (third serial number).

[0073] To effectively control the building environment and ensure monitoring accuracy, it is necessary to establish preset correspondences between cameras, air vents, and temperature sensors. These correspondences are based on their location relationships and possible control logic. First preset correspondence: Based on the location relationship between the camera and the air vent, a correspondence is established between a first code and a second code. For example, if a camera monitors multiple air vents within its monitoring range, these vents are grouped together. Second preset correspondence: Based on the location relationship between the camera and the temperature sensor, a correspondence is established between a first code and a third code. For example, if a camera monitors multiple temperature sensors within its monitoring range, these sensors are grouped together. Third preset correspondence: Based on the location relationship between the air vent and the temperature sensor, a correspondence is established between the second code and the third code. For example, the first preset correspondence could be S10A01-C10A01 (C10A0101-C10A0105), meaning that camera 01 in area A of the 10th floor establishes a first preset correspondence with the air outlet group of group 01 in area A of the 10th floor, and the air outlet group of group 01 in area A of the 10th floor includes air outlets C10A0101-C10A0105. The second preset correspondence could be S10A01-W10A01 (W10A0101-W10A0102), meaning that camera 01 in area A of the 10th floor establishes a second preset correspondence with the temperature sensor group of group 01 in area A of the 10th floor, and the temperature sensor group of group 01 in area A of the 10th floor includes temperature sensors W10A0101-W10A0102. The third preset correspondence can be W10A0101-(C10A0101-C10A0102), that is, the temperature sensor No. 01 of group 01 in area A of the 10th floor establishes a third preset correspondence with the air outlets No. 01-02 of group 01 in area A of the 10th floor.

[0074] By dividing each floor of the building into zones and assigning cameras, air vents, and temperature sensors to each zone, the central air conditioning control platform can more accurately monitor and control the environmental conditions of each area. The unique codes for cameras, air vents, and temperature sensors ensure that the central air conditioning control platform can accurately identify each device, thus avoiding confusion or misoperation. Through precise environmental control, the central air conditioning control platform can reduce unnecessary energy consumption while ensuring people's comfort. The unique codes and preset correspondences make the central air conditioning control platform easier to maintain and expand. When adding new cameras, air vents, or temperature sensors, simply assign them new codes and establish the corresponding preset correspondences. When a device malfunctions, it can also be quickly located, repaired, or replaced based on its code.

[0075] S120. When the number of people in the first image exceeds the first number threshold, the first code of the first camera is obtained, and the first air outlet group corresponding to the first camera is determined according to the first code based on the first preset correspondence.

[0076] When the number of people in the first image captured by the first camera exceeds a preset threshold, the central air conditioning control platform triggers a response mechanism. To determine the associated air vent group and temperature sensor group, the central air conditioning control platform needs to obtain the camera's first code. This is done by querying the camera management database or system configuration to find the first code corresponding to the first camera. Based on the previously established preset correspondence, the central air conditioning control platform then determines the first air vent group associated with the first camera.

[0077] S130. Based on the second preset correspondence, determine the target temperature sensor group corresponding to the first camera according to the encoding, obtain the first temperature value of the first sub-temperature sensor in the target temperature sensor group, and control the opening and closing of the corresponding air outlet in the first air outlet group according to the first temperature value. The first sub-temperature sensor is any one of the temperature sensors in the target temperature sensor group.

[0078] Based on the previously established second preset correspondence, the target temperature sensor group associated with the first camera is determined. After determining the target temperature sensor group, the central air conditioning control platform controls the activation of all temperature sensors in the target temperature sensor group and acquires the temperature value of each temperature sensor in the target temperature sensor group. Specifically, the central air conditioning control platform establishes a connection with each temperature sensor in the target temperature sensor group through a communication interface (such as wired or wireless), sends a temperature reading command to the first sub-temperature sensor, waits for the returned temperature value, receives and parses the returned temperature data to obtain the first temperature value. After acquiring the first temperature value, the target temperature sensor group will determine the environmental state of the current area based on this temperature value and control the opening and closing of the corresponding air outlet group accordingly. For example, if the temperature value is too high, the central air conditioning control platform may increase the number of air outlets opened or increase the opening degree of the air outlets; if the temperature value is suitable, the central air conditioning control platform may maintain the current state or make fine adjustments; if the temperature value is too low, the central air conditioning control platform may reduce the number of air outlets opened or reduce the air volume. The central air conditioning control platform calculates the required air outlet control parameters (such as the number of outlets open and the opening degree) based on a preset temperature control strategy (such as PID control algorithm, fuzzy control algorithm, etc.) and a first temperature value. It then sends control commands to the corresponding air outlet groups via the control interface to adjust their opening / closing status and airflow. The platform monitors the actual status changes of the air outlets and makes adjustments or optimizations as needed.

[0079] Figure 2This is a floor plan diagram of the intelligent building disclosed in the embodiments of this application, such as... Figure 2 As shown, the floor is divided into four areas: A, B, C, and D. Each area includes at least one camera, at least one temperature sensor, and at least one set of air vents. Taking area B as an example, camera 201 can cover the entire area. Area B includes air vents 202, 203, 204, 205, and 206, as well as temperature sensors 207 and 208. Air vents 202, 203, 204, 205, and 206 form a set of air vents and establish a first preset correspondence with camera 201. Temperature sensors 207 and 208 form a set of temperature sensors and establish a second preset correspondence with camera 201. Temperature sensor 207 establishes a third preset correspondence with air vents 202 and 203, and temperature sensor 208 establishes a third preset correspondence with air vents 204, 205, and 206. Figure 2 The embodiments of this application will be described.

[0080] In some embodiments, controlling the opening and closing of the corresponding air outlet in the first air outlet group according to the first temperature value includes:

[0081] The target air outlet group corresponding to the first sub-temperature sensor is determined according to the third preset correspondence.

[0082] When the first temperature value is greater than the first temperature threshold, the opening degree of the air outlet in the target air outlet group is increased or the number of air outlets opened in the target air outlet group is increased.

[0083] When the first temperature value is less than the second temperature threshold, the opening degree of the air outlet in the target air outlet group is reduced or the number of air outlets opened in the target air outlet group is reduced, and the second temperature threshold is less than the first temperature threshold.

[0084] The target air outlet group is part or all of the first air outlet group, such as Figure 2 As shown, region B includes two temperature sensors, 207 and 208. Each temperature sensor corresponds to a part of the first air outlet group. When region B includes only one temperature sensor, that temperature sensor will correspond to the entire first air outlet group. In this embodiment, when the first sub-temperature sensor is 207, the target air outlet group corresponding to 207 is a combination of air outlets 202 and 203. When the first sub-temperature sensor is 208, the target air outlet group corresponding to 208 is a combination of air outlets 204, 205, and 206.

[0085] When the first temperature value exceeds the first temperature threshold (e.g., 28°C), the central air conditioning control platform determines that the ambient temperature in the current area is high and requires increasing the amount of cold air to lower the temperature. For example, assuming that air outlet 202 is currently open and air outlet 203 is closed, and the opening degree of air outlet 202 is 50%, the opening degree of the air outlets in the target air outlet group can be increased to allow more cold air to flow into the area and lower the temperature; that is, the opening degree of air outlet 202 can be increased. If necessary, the central air conditioning control platform can also increase the number of open air outlets in the target air outlet group to further improve the cooling effect; that is, air outlet 203 can be opened. If the first temperature value exceeds the first temperature threshold by a large margin (e.g., the first temperature value exceeds the first temperature threshold by 2°C), the air outlets in the target air outlet group corresponding to other temperature sensors in the same area can also be opened. For example, in this embodiment, one or more of air outlets 204, 205, or 206 can be opened. When the first temperature value is lower than the second temperature threshold (e.g., 22°C), the central air conditioning control platform determines that the ambient temperature in the current area is low and requires a reduction in the amount of cooling air to maintain the temperature. This can be achieved by reducing the opening of the air outlets in the target air outlet group, decreasing the amount of cooling air flowing into the area, and maintaining a stable temperature. If necessary, the central air conditioning control platform can also reduce the number of open air outlets in the target air outlet group, further reducing the cooling effect. The second temperature threshold is lower than the first temperature threshold to ensure that the central air conditioning control platform can respond appropriately under different temperature conditions.

[0086] By associating temperature sensors with air vents, the central air conditioning control platform can precisely adjust the corresponding air vents for areas of temperature change. When a first temperature value exceeds a set first temperature threshold, the platform quickly increases the ventilation volume of the target air vent group, effectively reducing the temperature in that area. Conversely, when the temperature drops below a second temperature threshold, the platform reduces ventilation to prevent energy waste and maintain indoor temperature stability. Precise temperature control reduces unnecessary energy consumption, especially during off-peak hours or in areas with low population density. Simultaneously, timely temperature adjustments maintain indoor comfort. Through intelligent temperature control and adjustment, the central air conditioning control platform can make adjustments before users perceive temperature changes, providing a more comfortable and stable environment.

[0087] In some embodiments, increasing the opening degree of the air outlets in the target air outlet group or increasing the number of open air outlets in the target air outlet group when the first temperature value is greater than the first temperature threshold includes:

[0088] When the first temperature value is greater than the first temperature threshold, the first opening of the air outlet or the first number of air outlets is increased based on the difference between the first temperature value and the first temperature threshold. The second temperature value of the first sub-temperature sensor in the target temperature sensor group is obtained at a second preset time interval, where the second preset time is less than the first preset time.

[0089] When the second temperature value is greater than the first temperature threshold, all air outlets in the target air outlet group are opened and the opening degree of the air outlets is set to the first target opening degree.

[0090] When the difference between the first temperature value and the first temperature threshold is greater than zero and less than one, priority is given to increasing the opening degree of the already opened air outlets. For example, if the first temperature value is 28.5℃, the first temperature threshold is 28℃, and the difference is 0.5, if only one air outlet is open in the current target air outlet group, the opening degree of that air outlet can be increased by 40%. If two air outlets are open in the current target air outlet group, the opening degree of each of the two air outlets can be increased by 20%. Of course, this is just an example, and the specific value of the opening degree adjustment can be further calculated based on the contribution rate of the percentage increase in opening degree to temperature reduction. When the difference between the first temperature value and the first temperature threshold is greater than or equal to one, priority is given to increasing the number of open air outlets, which can reduce the temperature of the target area as quickly as possible. After a period of time, the current temperature value of the first sub-temperature sensor (i.e., the second temperature value) is acquired again. It is then determined whether the current temperature value is greater than the first temperature threshold. If the current temperature value is still greater than the first temperature threshold, it indicates that the cooling effect is not significant, and all air outlets in the target air outlet group can be opened, with the opening of each outlet set to its maximum. If the current temperature value is less than or equal to the first temperature threshold, it indicates that the cooling effect has met expectations, and the current operating state of the target air outlet group can be maintained.

[0091] By determining the adjustment range based on temperature differences, the central air conditioning control platform achieves more precise temperature control. This helps avoid discomfort caused by excessive temperature fluctuations and also helps save energy. The platform monitors the temperature again at second preset intervals and takes more aggressive measures when necessary, ensuring a rapid response to ambient temperature. This contributes to improved indoor comfort. The gradual adjustment strategy helps avoid unnecessary energy waste. When the temperature is only slightly above the threshold, the platform only needs to fine-tune the air vent settings without immediately maximizing ventilation. Through precise control and rapid response, the central air conditioning control platform provides users with a more stable and comfortable indoor environment, thereby improving user satisfaction and comfort.

[0092] In some embodiments, reducing the opening degree of the air outlets in the target air outlet group or reducing the number of open air outlets in the target air outlet group includes:

[0093] When the first temperature value is less than the second temperature threshold, the second opening degree of the air outlet or the second number of air outlets is reduced based on the difference between the first temperature value and the second temperature threshold. The second temperature value of the first sub-temperature sensor in the target temperature sensor group is obtained at a second preset time interval, where the second preset time is less than the first preset time.

[0094] When the second temperature value is less than the second temperature threshold, all unmarked air outlets in the target air outlet group are closed, and the opening degree of the marked air outlets is set to the second target opening degree.

[0095] When the difference between the first temperature value and the second temperature threshold is greater than zero and less than one, priority is given to reducing the opening degree of the already opened air outlets. For example, if the first temperature value is 21.5℃, the first temperature threshold is 22℃, and the difference is 0.5, if only one air outlet is open in the current target air outlet group, the opening degree of that air outlet can be reduced by 40%. If two air outlets are open in the current target air outlet group, the opening degree of each of the two air outlets can be reduced by 20%. Of course, this is just an example, and the specific value of the opening degree adjustment can be further calculated based on the contribution rate of the percentage reduction in opening degree to the temperature reduction. When the difference between the first temperature value and the first temperature threshold is greater than or equal to one, priority is given to reducing the number of open air outlets, so that the temperature of the target area can be adjusted to the preset range as quickly as possible. After a period of time, the current temperature value of the first sub-temperature sensor (i.e., the second temperature value) is acquired again. It is then determined whether the current temperature value is lower than the first temperature threshold. If the current temperature value is still lower than the first temperature threshold, it indicates that the cooling effect has far exceeded the demand. In this case, all unmarked air outlets in the target air outlet group can be closed, and the opening of the marked air outlets can be set to the minimum opening. Some air outlets need to be retained to maintain normal cooling in the building. These air outlets are marked, and only the marked air outlets are opened when maintaining minimum cooling effect. If the current temperature value is greater than or equal to the first temperature threshold, it indicates that the cooling effect has reached the expected level, and the current operating state of the target air outlet group can be maintained.

[0096] When the indoor temperature is below the desired level, the central air conditioning control platform can significantly reduce unnecessary energy consumption by decreasing the number or opening of air vents. This not only helps reduce operating costs but also reduces the burden on the environment. By dynamically adjusting the opening or number of air vents based on temperature differences, the central air conditioning control platform can achieve more precise temperature control. This helps avoid excessive temperature fluctuations and maintains the stability of the indoor environment. By gradually adjusting the state of the air vents, the central air conditioning control platform can gradually reduce the indoor temperature without affecting user comfort. This smooth temperature change avoids a sharp drop in temperature, thus providing a better experience. The central air conditioning control platform acquires the temperature value again at a second preset time interval and makes corresponding adjustments based on temperature changes. This rapid response mechanism helps to promptly address changes in indoor temperature, ensuring that the indoor environment remains within a comfortable range. The entire strategy relies on an automated control system, making indoor temperature management more intelligent. The central air conditioning control platform can automatically make decisions based on real-time data without manual intervention, improving management efficiency and accuracy. This strategy is not only applicable to temperature control of a single room or area but can also be extended to the combined management of the entire building or multiple rooms. A unified control system enables coordinated control of multiple areas, further improving energy efficiency and comfort.

[0097] In some embodiments, the control method further includes:

[0098] When all the first temperature values ​​in the target temperature sensor group are greater than the first temperature threshold, all the air outlets in the first air outlet group are opened, and the second temperature value of the first sub-temperature sensor in the target temperature sensor group is obtained at a third preset time interval, wherein the third preset time is less than the first preset time.

[0099] When all the second temperature values ​​in the target temperature sensor group are greater than the first temperature threshold, it is determined whether all the air outlets in the second air outlet group are open. The second air outlet group is the air outlet group corresponding to the second camera. The second camera refers to the camera with the first serial number adjacent to the first camera.

[0100] When all the air outlets in the second air outlet group are open, the air outlet temperature of the central air conditioning is reduced.

[0101] See also Figure 2, the target temperature sensor group is temperature sensors 207 and 208. When the temperature values of temperature sensors 207 and 208 are both greater than the first temperature threshold, all the air outlets in the first air outlet group are opened, that is, air outlets 202, 203, 204, 205 and 206 are opened. After an interval of the third preset time, the current temperature values (i.e., the second temperature values) of temperature sensors 207 and 208 are obtained again. When all the second temperature values are greater than the first temperature threshold, it indicates that the current cooling effect does not meet the expectation. At this time, it is necessary to determine whether all the air outlets in the second air outlet group are opened. The second air outlet group is the air outlet group corresponding to the second camera, and the second camera refers to the camera whose first serial number is adjacent to the first camera. In the embodiment of the present application, the second camera can be camera 211 or camera 221. When the second camera is camera 211, the second air outlet group is air outlets 212, 213, 214, 215 and 216. When the second camera is camera 221, the second air outlet group is air outlets 222, 223, 224, 225 and 226. If air outlets 212, 213, 214, 215, 216 and 222, 223, 224, 225, 226 are all in the open state at this time, it indicates that the cooling effect on the current floor may be difficult to achieve the expected effect, and the air outlet temperature of the current floor can be reduced. If the air outlets on other floors are also all in the open state at this time, or the ratio of the number of air outlets in the whole building in the open state to the total number of air outlets exceeds a certain preset value (such as 90%), the air outlet temperature of the whole building can be reduced.

[0102] When all the first temperature values in the target temperature sensor group exceed the first temperature threshold, the central air-conditioning control platform quickly opens all the air outlets in the first air outlet group to quickly reduce the temperature in the target area. When it is found that the temperature in the target area continues to exceed the threshold, the central air-conditioning control platform will further determine whether all the air outlets in the second air outlet group corresponding to the second camera adjacent to the first camera have been opened. This linkage control strategy takes into account the mutual influence between adjacent areas and helps to achieve a more balanced temperature in a larger range. If all the air outlets in the second air outlet group have been opened, but the temperature still exceeds the threshold, the central air-conditioning control platform will choose to reduce the air outlet temperature of the central air-conditioning. This intelligent adjustment method can ensure that while meeting the cooling demand, unnecessary energy waste is avoided. Through refined control and intelligent adjustment, the central air-conditioning control platform can provide a more comfortable environment for users and improve the overall experience of users.

[0103] Optionally, the average value of temperature sensors 207 and 208 can be used as the first temperature value. This average value can be used to regulate all air outlets in area B as a whole. The regulation method can be as described above and will not be repeated here. To avoid abnormal regulation caused by temperature sensor failure, the difference between the temperature values ​​of temperature sensor 207 and temperature sensor 208 can be calculated. If the difference is greater than a preset threshold (e.g., 3°C), it indicates that one of the temperature sensors 207 and 208 may be malfunctioning. In this case, the temperature values ​​of temperature sensors 207 and 208 can be measured again, and temperature sensors 207 and 208 can be verified in conjunction with the temperature values ​​of other sensors. For example, if the temperature difference between temperature sensors 218 and 227 and temperature sensor 207 is less than the preset threshold, and the temperature difference between temperature sensors 228 and temperature sensor 208 is greater than the preset threshold, it indicates that temperature sensor 208 may be malfunctioning.

[0104] In some embodiments, the control method further includes:

[0105] When all the first temperature values ​​in the target temperature sensor group are less than the second temperature threshold, the first preset air outlet in the first air outlet group is kept open, the unmarked air outlet in the first air outlet group is closed, and the third temperature value of the first sub-temperature sensor in the target temperature sensor group is acquired at a third preset time interval, wherein the third preset time is less than the first preset time.

[0106] When all the third temperature values ​​in the target temperature sensor group are less than the second temperature threshold, it is determined whether all the unmarked air outlets in the second air outlet group are in a closed state. The second air outlet group is the air outlet group corresponding to the second camera. The second camera refers to the camera with the first serial number adjacent to the first camera.

[0107] When all unmarked air outlets in the second air outlet group are closed, the air outlet temperature of the central air conditioning system is increased.

[0108] See also Figure 2The target temperature sensor group consists of temperature sensors 207 and 208. When the temperature values ​​of both temperature sensors 207 and 208 are less than the second temperature threshold, assuming the air outlets are marked as 203 and 206, the unmarked air outlets in the first air outlet group are closed, i.e., air outlets 202, 204, and 205 are closed. The current temperature values ​​(i.e., the second temperature values) of temperature sensors 207 and 208 are obtained again after a third preset time interval. When all second temperature values ​​are less than the second temperature threshold, it indicates that the current cooling effect has far exceeded expectations. At this point, it is necessary to determine whether all unmarked air outlets in the second air outlet group are closed. The second air outlet group is the air outlet group corresponding to the second camera. The second camera refers to the one with the first serial number and the... In this embodiment, the second camera adjacent to the first camera can be either camera 211 or camera 221. When the second camera is camera 211, the second air outlet group consists of air outlets 212, 213, 214, 215, and 216. When the second camera is camera 221, the second air outlet group consists of air outlets 222, 223, 224, 225, and 226. Assuming the air outlets are marked as 212, 215, 222, and 225, if air outlets 213, 214, 216 and 223, 224, and 226 are all closed at this time, and air outlets 212, 215, 222, and 225 are at their minimum opening, it indicates that the cooling effect of the current floor may far exceed the expected effect, and the air outlet temperature of the current floor can be increased. If the unmarked air outlets on other floors are also closed at this time, the air outlet temperature of the entire building can be increased.

[0109] When all first temperature values ​​within the target area are below the second temperature threshold, the central air conditioning control platform closes unmarked air outlets, reducing unnecessary energy consumption while maintaining temperature stability in the target area. Temperature values ​​are acquired again at a third preset interval, meaning the central air conditioning control platform avoids continuous high-frequency temperature monitoring, thus ensuring both timely temperature adjustment and energy efficiency. The system considers not only the temperature of the current target area but also the status of air outlets in adjacent areas. Only when all unmarked air outlets in adjacent areas are confirmed to be closed is the central air conditioning outlet temperature further increased. This coordinated control strategy avoids mutual interference between different areas due to temperature adjustments, improving the overall system's coordination and stability. Because the central air conditioning control platform can dynamically adjust the air outlet status based on real-time data from temperature sensors, it ensures that the temperature within the camera-monitored target area remains within a comfortable and safe range. The entire control process requires no manual intervention, executing automatically based on preset thresholds and logical rules, achieving intelligent and automated temperature management, reducing labor costs, and improving system response speed and reliability.

[0110] In some embodiments, the control method further includes:

[0111] A second image is acquired from a third camera at a preset location. Facial recognition is performed on the second image, and the recognition result is matched with a preset database to determine the work destination of the target person in the second image. The work destination includes the work floor and work area. The preset database is used to store the correspondence between the target person and the work destination.

[0112] Determine whether the target person is the first person matched with the work destination within the current period;

[0113] When the target person is the first person matched with the work destination in the current cycle, open the first-level air outlet of the work destination;

[0114] If the target person is not the first person matched to the work destination in the current period, increment the current number of people in the work destination by one, and determine whether the current number of people is greater than the second number threshold.

[0115] When the current number of people exceeds the second number threshold, open the second-level air outlet of the work destination.

[0116] A third camera at a pre-defined location (such as a lobby or elevator entrance) captures a second image of people entering the area. The facial recognition module analyzes this second image, identifying faces and extracting features from each face. These features are then compared to data in a pre-defined database. This database stores the facial features of each target person and their corresponding work destination information. The system compares the facial features extracted from the image with the data in the database to find matching target persons and their work destinations, which typically include specific floor and area information. Once a target person is identified and their work destination determined, the system checks if other people have already been matched to the same work destination within the current period (e.g., one day). If the target person is the first to be matched to that work destination, the system opens the first-level air vent for that destination. If the target person is not the first to arrive, the system performs a headcount count; when the headcount exceeds a threshold, the second-level air vent opens. The first-level air vent can be a marked vent, and the second-level air vent can be an unmarked vent for the target work location.

[0117] For example, at 8:00 AM, the third camera in the office building lobby captures a second image, identifying person M. By matching this image with a preset database, M's work destination is determined to be area B on the 15th floor. The system then checks if any employees from area B have already entered the building that day. If not, M is the first employee to arrive in area B, and the first-level air vents in area B are opened to ensure a comfortable temperature for M upon entry. If so, M is not the first employee to arrive in area B, and the current number of people in area B is incremented. The system then checks if the current number exceeds a second threshold. If it does, the second-level air vents in area B are opened. Opening the first-level air vents at the target work destination is typically to ensure basic comfort in that area while avoiding energy waste, as only one person is present at that moment. The system tracks the number of people in the area in real time and determines if the current number exceeds the preset second threshold. This second threshold is set based on the area's size, design capacity, and comfort requirements. If the current number of people exceeds a threshold, the system will open the second-level air vents. This is typically to further enhance comfort in the area, ensure air circulation, and reduce the decrease in comfort caused by overcrowding. The entire control process is real-time, with the system dynamically adjusting the vent status based on changes in occupancy. This ensures that the central air conditioning system can provide optimal comfort according to actual needs, while also achieving efficient energy utilization.

[0118] The system automatically recognizes faces and matches them against a pre-set database to determine the target person's work destination, thereby controlling the air vent status. The entire process requires no manual intervention, achieving intelligent and automated environmental control. The system precisely controls the air vents based on the target person's presence, avoiding unnecessary energy consumption. When only a few people arrive, opening only the first-level air vents is sufficient, achieving energy savings. As the number of people increases, the second-level air vents are opened as needed to ensure environmental comfort while maintaining efficient operation. The system automatically adjusts the environment based on the target person's work destination, ensuring a comfortable environment upon entering the work area. This contributes to improved user satisfaction and comfort. The system can detect and match the target person's work destination information in real time, dynamically adjusting the air vent status based on the current number of people. This real-time capability and flexibility allow the system to adapt to various complex usage scenarios and meet the needs of different users. It can be integrated with other intelligent systems (such as access control systems and attendance systems) to achieve information sharing and collaborative work. Furthermore, with continuous technological development, the system can be further expanded in functionality, such as adding automatic adjustment of environmental parameters like carbon dioxide and humidity.

[0119] In some embodiments, the control method further includes:

[0120] The hot and cold zones in each cycle are determined based on the rate of change of personnel, as well as the time when the hot and cold zones are generated. The hot zone refers to the area where the number of personnel increases exceeds a third threshold within a preset time, and the cold zone refers to the area where the number of personnel decreases exceeds a fourth threshold within a preset time.

[0121] When the same target hot zone or the same target cold zone is generated at similar times in multiple cycles, the first preset time of the target hot zone or the target cold zone is determined based on the generation times of the multiple cycles. The generation times being similar means that the difference between two generation times is less than a first time threshold.

[0122] When the second preset time is reached, the corresponding air outlet is opened according to the temperature of the target hot zone, and / or the corresponding air outlet is closed according to the temperature of the target cold zone. The second preset time is the time before the first preset time, and the difference between the second preset time and the first preset time is less than the second time threshold.

[0123] Monitor changes in the number of personnel in each work area and statistically analyze increases and decreases in personnel count over preset time periods (e.g., 10 minutes). If, within a preset time period, the increase in personnel in an area exceeds a third threshold (this threshold can be set based on actual conditions, such as an increase of 10 people or 20%), then this area is defined as a "hot zone." Conversely, if the decrease in personnel in an area exceeds a fourth threshold (e.g., a decrease of 5 people or 10%), then this area is defined as a "cold zone." Record the time of occurrence of each hot and cold zone and pay attention to areas where hot or cold zones frequently occur. In particular, when the same area is identified as a hot or cold zone in multiple periods, and the occurrence times of these periods are close (i.e., the difference between two occurrence times is less than a first time threshold, such as less than 5 minutes), then this area is considered a "target hot zone" or "target cold zone." This step helps the system identify areas with regular changes, enabling prediction and early intervention. For example, if area A on the basement level is defined as a hot zone at 18:05 on March 1st, 18:07 on March 2nd, 18:02 on March 3rd, and 18:09 on March 4th, then area A on the basement level can be defined as a target hot zone. The first preset time can be 18:02 (the earliest of the above times), and the second preset time can be 18:00, meaning that the air vents of area A on the basement level can be opened in advance at 18:00 on March 5th. Of course, if the hot zone has a clear periodicity, i.e., it occurs on weekdays but not on holidays, then if March 5th is a holiday, the air vents of area A on the basement level will not be opened in advance.

[0124] Once a target hot or cold zone is identified, the system predicts future demand based on temperature change patterns in these areas and intervenes in advance. Specifically, when a second preset time is reached (this time is some time before the first preset time for the target hot or cold zone, and the difference between the two is less than a second time threshold, such as 2 minutes in advance), the system will open the corresponding air outlets in advance based on the temperature of the target hot zone to increase air circulation and cooling effect. Similarly, for the target cold zone, the system will close the corresponding air outlets in advance based on the temperature to reduce energy consumption and maintain the temperature of that area.

[0125] By predicting the emergence of hot and cold zones, the system can intervene in advance, ensuring that environmental conditions are adjusted before changes in personnel numbers occur, thus improving response speed and efficiency. Through precise control of air vent opening and closing, the system avoids unnecessary energy consumption, especially in cold zones where closing vents significantly reduces energy consumption. The system provides a comfortable environment based on regional temperature variation patterns, ensuring personnel work at a suitable temperature in both hot and cold zones. The entire process achieves intelligent management, requiring no manual intervention, reducing management costs and improving management efficiency.

[0126] In some embodiments, the control method further includes:

[0127] Determine if the current brightness of the target area is less than the brightness threshold;

[0128] When the current brightness of the target area is less than the brightness threshold, the third image of the target area is obtained by the fourth camera, and it is determined whether the number of people in the third image exceeds the third number threshold, wherein the third number threshold is less than the first number threshold.

[0129] When the number of people in the third image exceeds the third number threshold, determine the number of people in the third image who are in a preset pose and the total number of people, calculate the ratio of the number of people to the total number of people, and determine whether the ratio is less than the ratio threshold.

[0130] When the ratio is less than the ratio threshold, reduce the number of air outlets or reduce the opening of the air outlets.

[0131] The system monitors the current brightness of the target area, typically through a brightness sensor or the built-in brightness detection function of the camera. When the system detects that the current brightness of the target area is less than a preset brightness threshold, subsequent operations are triggered. Alternatively, subsequent operations are triggered when the system detects that the lights in the target area are turned off or the curtains are drawn, as this often indicates a meeting or lunch break. Whether to turn off the lights or draw the curtains can be determined by sensors located on light switches or curtain rods. When the brightness is below the brightness threshold, the system activates a fourth camera (or other designated camera) to capture an image of the target area—the third image. The system then performs people recognition on this third image. This is typically achieved through image analysis techniques (such as object detection, background segmentation, etc.) to determine if the number of people in the image exceeds a preset third people threshold. This threshold is usually smaller than the first people threshold to account for situations where people may be more clustered or less active in low-light conditions. In some embodiments, the third people threshold can be set to zero. If the number of people in the third image exceeds the third people threshold, the system further analyzes the postures of the people in the image. This can be achieved through a posture recognition algorithm. This algorithm can identify a person's current posture and determine whether the current posture is a preset posture. The preset posture can be a normal working posture, where the head and upper body are approximately on the same plane, and the upper body and thighs are approximately perpendicular. Any abnormal working posture is not considered a preset posture, such as lying down, prone, or standing. The algorithm calculates the ratio of people in preset postures to the total number of people. This ratio reflects the proportion of people in a working state in the current area. The algorithm then determines whether the calculated ratio is less than a preset ratio threshold. The ratio threshold is usually set according to the actual application scenario and user needs, and is used to determine whether the air vent settings need to be adjusted. If the ratio is less than the ratio threshold, the system will assume that most people in the current area are not working or taking a lunch break, and therefore will reduce the number of air vents or reduce the opening of the air vents. This helps save energy, reduce noise, and provide a more comfortable environment for people.

[0132] In some embodiments, the control method further includes:

[0133] Acquire the fourth image of the fifth camera in the target area, and determine the size and opening angle of the doors and windows in the target area based on the fourth image;

[0134] When the opening angle of a door or window in the target area is greater than a first angle threshold, a prompt is sent to the administrator to close the door or window.

[0135] When the opening angles of the doors and windows in the target area are all less than or equal to the first angle threshold, the fourth temperature value at the target time is predicted based on the current operating mode, the size of the doors and windows, and the opening angle. The target time is the time corresponding to the target operating duration of the current operating mode.

[0136] Obtain the fifth temperature value at the target time, calculate the difference between the fourth and fifth temperature values, and when the difference is greater than the difference threshold, send a prompt to the administrator to clean the air conditioner.

[0137] A fifth camera in the target area captures real-time video streams or still images (i.e., the fourth image). This camera should be positioned to clearly observe the doors and windows in the target area. The captured fourth image is then analyzed. By applying image recognition technologies (such as edge detection and contour recognition), the system can identify doors and windows in the image and further calculate their size and opening angle. Once the system determines the opening angles of the doors and windows, it compares these angles with a preset first angle threshold. If the opening angle of any door or window is greater than the first angle threshold, the system considers that the opening of these doors or windows may have a significant impact on the indoor temperature and therefore sends a prompt to the administrator, suggesting that they close these doors or windows. If the opening angles of all doors and windows in the target area are less than or equal to the first angle threshold, the system enters a temperature prediction mode. First, it determines the current central air conditioning operating mode (i.e., the number and opening degree of the air vents) and the target operating duration of this mode. Next, the system combines the current operating model with the size and opening angle of doors and windows, using a temperature prediction algorithm (such as a machine learning-based prediction model) to predict the indoor temperature at the target time (i.e., the time corresponding to the target duration of the current operating mode), which is the fourth temperature value. At the target time, the system acquires the actual indoor temperature value, which is the fifth temperature value. The fifth temperature value can be obtained through a temperature sensor or other temperature detection device. Then, the system calculates the difference between the predicted fourth temperature value and the actual fifth temperature value. The method for calculating the difference can be defined according to specific needs; for example, absolute difference or relative difference can be used. The system determines whether the calculated difference is greater than a preset difference threshold. If the difference is greater than the threshold, the system considers that the actual operating effect of the air conditioner deviates significantly from the predicted value, possibly due to dust accumulation inside the air conditioner, filter blockage, or other reasons. Therefore, the system will issue a prompt to the administrator, suggesting that they clean or maintain the air conditioner.
