By taking the lighting lamp closing proportion as a condition of the air conditioner running state and the number of persons in the office area as another condition of the air conditioner running state, the working state of the air conditioner in the air conditioning area of the building is more accurately analyzed.

[0025] Optionally, the adjusting and controlling of the air conditioner according to the preset air conditioner adjustment strategy comprises:

[0026] When the air conditioner type is the office area air conditioner or the public area air conditioner, whether the lighting lamp proportion is greater than the preset closing proportion and whether the person flow data is less than the preset person flow data are determined after the first preset time;

[0032] When the air conditioner type is the leisure area air conditioner, the air conditioner is controlled to be closed.

[0033] By adopting the technical scheme, when in the office area and the public area, there may be a situation that persons leave but come back soon, and when in this situation, the air conditioner is gradually controlled to be in the first energy-saving mode and the second energy-saving mode, thereby reducing the situation that the air conditioner is frequently turned on and off after persons temporarily go out in the office area or the public area, and saving energy of the air conditioner; when the air conditioner type is the leisure area air conditioner, persons in the leisure area are usually temporary, and the situation that persons go out and come back is low, so the air conditioner is directly controlled to be closed.

[0034] Optionally, the air conditioner includes an air outlet fan blade device, and the environmental information further includes outdoor temperature data, humidity data, and wind speed data; if there are no abnormal energy consumption conditions, the method further includes:

[0041] The air conditioner's temperature setting and the opening degree of the air outlet fan blades are adjusted based on the temperature difference and preset fine-tuning rules.

[0042] By adopting the above technical solution, if the air-conditioned area is not within the preset temperature range, the temperature of the air-conditioned area may be affected by other factors, resulting in a small deviation between the temperature and the preset temperature range. Therefore, the temperature of the air conditioner and the opening degree of the outlet fan blade device are adjusted according to the temperature difference and preset fine-tuning rules to adjust the temperature value within the preset temperature range, thereby improving the comfort of people in the building.

[0043] Optionally, after adjusting the air conditioner's temperature and the opening degree of the air outlet fan blades based on the temperature difference and preset fine-tuning rules, the method further includes:

[0044] After the air conditioner has been running for a third preset time, it is determined whether the difference between the temperature of the corresponding area of ​​the air conditioner in the building and the minimum or maximum value of the preset temperature range is greater than the preset temperature threshold.

[0045] If the temperature exceeds the preset temperature threshold, the compressor of the air conditioner is judged to be abnormal based on the compressor inverter voltage, compressor inverter current and preset air conditioner indoor and outdoor unit parameters.

[0046] If so, it is determined that the air conditioner has a second abnormality, and an operational abnormality information is generated;

[0050] By adopting the above technical solution, whether the hardware equipment of the air conditioner for detecting temperature abnormality in the building is abnormal is determined by detecting the frequency converter voltage of the compressor, the frequency converter current of the compressor, the outdoor fan current and the outdoor fan. If the temperature abnormality is caused by the abnormality of the hardware equipment of the building, the air conditioner with the second abnormality or the third abnormality will consume a large amount of electricity in use, and the energy waste of the air conditioner is increased. The management personnel is reminded to maintain the air conditioner in time according to the location information and the running abnormality information of the abnormal air conditioner, so as to reduce the energy waste of the air conditioner.

[0051] Optionally, the generating of the air conditioner maintenance prompt information according to the location information of the air conditioner and the sending of the air conditioner maintenance prompt information to the management terminal comprise:

[0054] If yes, the corresponding maintenance priority sequence is determined according to the air conditioner type of the air conditioner corresponding to each maintenance prompt information, and each maintenance prompt information is sent to the management terminal according to the maintenance priority sequence; wherein the maintenance priority corresponding to the office area air conditioner type is higher than the maintenance priority corresponding to the public area air conditioner type, and the maintenance priority corresponding to the public area air conditioner type is higher than the maintenance priority corresponding to the leisure area air conditioner.

[0055] By adopting the above technical solution, the corresponding maintenance priority is reasonably arranged according to the different air conditioner type corresponding to the air conditioner use demand priority, the maintenance priority corresponding to the office area air conditioner type is set to the highest, the public area air conditioner type is followed, and the leisure area air conditioner type is the lowest, so that the air conditioner with higher maintenance priority is arranged for maintenance in priority according to the urgency.

[0056] Optionally, after the corresponding maintenance priority sequence is determined, it further comprises,

[0057] determining whether a plurality of air conditioners are in the same maintenance priority, if yes, obtaining air conditioner use information of each air conditioner in the same maintenance priority in a previous time period;

[0058] calculating, based on a preset calculation rule, a use priority index corresponding to each air conditioner in the same maintenance priority according to the air conditioner use information;

[0059] sorting the use priority indexes corresponding to the air conditioners in the same maintenance priority to obtain a maintenance sub-priority corresponding to each air conditioner in the same maintenance priority; wherein the greater the use priority index of the air conditioner is, the higher the maintenance sub-priority corresponding to the air conditioner is.

[0060] By adopting the above technical solution, the air conditioners in the same maintenance priority are arranged for maintenance according to the maintenance sub-priority, which improves the experience of the personnel in the building and ensures the orderly air conditioner maintenance work.

[0061] In a second aspect, the application provides a building heating ventilation air conditioner control device, which adopts the following technical solution:

[0077] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0078] In addition, the term “and / or” in this document is only to describe the association relationship of the associated objects, which means that there can be three kinds of relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone. In addition, the character “ / ” in this document generally represents an “or” relationship between the associated objects unless otherwise specified.

[0079] The embodiment of the present application provides a building HVAC control method, which is executed by an electronic device, and the electronic device can be a server or a mobile terminal device. The server can be a physical server, a server cluster composed of multiple physical servers, a distributed system, or a cloud server providing cloud computing services. The mobile terminal device can be a tablet computer, a notebook computer, a mobile phone, a desktop computer, or the like.

[0080] The embodiment of the present application will be further described in detail below with reference to the accompanying drawings. As shown in the drawings, the main flow of the method is described as follows (steps S101-S104). Figure 1

[0081] In step S101, the electronic device acquires air conditioner basic information corresponding to each air conditioner in the building and environment information of an area where the air conditioner is located. The air conditioner basic information includes an air conditioner running state, an air conditioner type, and an air conditioner position. The environment information includes people flow data and lighting lamp data.

[0082] In an embodiment, the air conditioner running state includes a closed state and an open state, and the open state further includes a first energy-saving mode and a second energy-saving mode or a sleep mode. The electronic device is communicatively connected to each air conditioner in the building to control the air conditioner running state of the air conditioner, such as controlling the opening and closing of the air conditioner.

[0083] The air conditioner type and the air conditioner position can be pre-stored in air conditioner information data. The building is divided into multiple air conditioner areas according to the positions of the air conditioners in the building and the different uses of each floor area in the building, and each air conditioner area corresponds to multiple air conditioners. The air conditioners are divided into different types according to the different areas. The air conditioner type includes an office area air conditioner type, a public area air conditioner type, and a leisure area air conditioner type. Each air conditioner type can be determined according to the actual installation position of each air conditioner, and the air conditioner position is pre-recorded when the air conditioner is installed. For example, the area where multiple offices or companies in the building have employees working and working is an office area, and accordingly, the type of the multiple air conditioners in the office area is an office area air conditioner type. The hall area, the toilet area, the tea room, and the corridor area in the building are public areas, and accordingly, the type of the multiple air conditioners in the public area is a public area air conditioner. The restaurant area and the smoking area in the building are leisure areas, and accordingly, the type of the multiple air conditioners in the leisure area is a leisure area office type.

[0084] It should be noted that other areas with different functions in the building can also be set, and are not limited to the above three types of air conditioners.

[0085] ​According to the distribution of air conditioners, the lighting lamp detection module and the passenger flow detection module are arranged in each air conditioner area, and the electronic device can obtain the running state information of the lighting lamp in each air conditioner area and the passenger flow data and the personnel distribution in each air conditioner area.

[0086] In step S102, whether the air conditioner has an energy consumption abnormality is determined based on the passenger flow data, the lighting lamp data, the air conditioner type and the running state of the air conditioner.

[0087] The air conditioner in the building is usually in a high output demand period during the daily working period, and the output demand is relatively low at other times. However, during the working period, the air conditioner in the office area may be forgotten to be turned off due to company team building or attendance and other situations, and the air conditioner is still running during this period, which causes waste of air conditioner resources. In the leisure area and the public area, there may also be situations where no one needs to use.

[0088] In the office area, the lighting lamp in the office area is turned on during the office time. Usually, people will not forget to turn off the lighting lamp due to the situation of leaving work, lunch break or team building, etc. Therefore, the running state of the air conditioner in the building is controlled by the lighting lamp data and the passenger flow data in the building.

[0089] In an embodiment, specifically, as shown in Figure 2 S102 includes the following sub-steps (steps Sa~Sg):

[0090] In step Sa, the lighting lamp closing ratio of the area where the air conditioner is located is calculated.

[0091] In an embodiment, the lighting lamps in the air conditioner area where the air conditioner is located are divided. The total number of lighting lamps in the air conditioner area is pre-set in the electronic device, denoted as the first number. The electronic device obtains the number of lighting lamps that are turned off in the air conditioner area through the lighting detection module, denoted as the second number. The lighting lamp closing ratio of the air conditioner area can be calculated by the ratio of the second number to the first number. For example, there are fifty lighting lamps in the office area of a certain floor of Building A. The lighting lamp detection module detects that the number of lighting lamps that are turned off in the office area of the floor is forty-five. Then, the lighting lamp closing ratio of the air conditioner area is calculated as 45 / 50.

[0092] In the above embodiment, the lighting lamp detection module detects the second number of lighting lamps that are turned off according to the pre-set lighting lamp detection time, that is, the second number is a variable. It can be understood that the number of lighting lamps that are turned off in the office area is affected by the activities of the personnel, and the personnel leave the office area and turn off the lighting lamps.

[0093] Step Sb, determining the preset off ratio of the lighting lamp corresponding to the area where the air conditioner is located according to the type of the air conditioner based on the first preset mapping relationship;

[0094] In an embodiment, the first preset mapping relationship is the relationship between the lighting lamp off ratio and the air conditioner running state. For example, taking step Sa as an example, the lighting lamp off ratio is 45 / 50, and the preset off ratio of the lighting lamp in the first preset mapping relationship in the office area is 4 / 5 according to the type of the air conditioner.

[0095] The electronic device records the off state of the lighting lamp and the running state of the air conditioner in a day according to the preset lighting lamp detection time. The first preset mapping relationship can be obtained by training a neural network model according to the historical off state of the lighting lamp and the running state of the air conditioner in the air conditioner area. The neural network model can be a convolutional neural network model.

[0096] Since there are cases where the public area and the rest area except the office area do not turn on the lighting lamp but use the air conditioner during the day. Therefore, the air conditioner in the public area and the rest area, that is, the air conditioner of the type of the public area and the rest area, is determined according to the preset air conditioner monitoring time. The preset off ratio of the lighting lamp corresponding to the area is determined according to the preset air conditioner monitoring time. The day is divided into two time periods, the first time period is from 6 o'clock to 17 o'clock, and the second time period is from 17 o'clock to the next day 6 o'clock. When the air conditioner of the above two air conditioner types is located in the first time period, the preset off ratio is set to 0, and when the air conditioner of the above two air conditioner types is located in the second time period, the preset off ratio of the lighting lamp corresponding to the area is determined according to the first preset mapping relationship obtained by training the neural network model.

[0097] In the above embodiment, the preset off ratios corresponding to different air conditioner types are all different, which are obtained by training the historical air conditioner running state, the lighting lamp off ratio, and the use of the air conditioner of different types in the building. And the above description is only illustrative, and can also be set according to other air conditioner use habits, and the embodiments of the present application are not limited thereto.

[0098] Step Sc, determining the preset people flow data corresponding to the people flow of the area where the air conditioner is located according to the type of the air conditioner based on the second preset mapping relationship;

[0099] In an embodiment, the second mapping relationship is the relationship between the people flow data and the air conditioner running state. The electronic device records the number of personnel and the running state of the air conditioner in a day according to the preset people flow detection time. The second preset mapping relationship can be obtained by training a neural network model according to the historical number of personnel and the running state of the air conditioner in the air conditioner area.

[0100] Due to the existence of offices or temporary absence of the whole company in the office area, in this case, it is often not to turn off the lighting, indicating that the company is in operation. For example, the case of taking a group photo outside the building by all employees of the company, if the going-out time is 2 hours, according to the lighting lamp closing proportion, the air conditioner in the office area is always on, which also causes a certain waste of energy. In order to further save the air conditioning energy, in addition to using the lighting lamp closing proportion as the condition of the air conditioning running state, the number of personnel in the office area is also detected as the condition of the air conditioning running state, so that the opening and closing of the air conditioner in the building air conditioning area is more accurate.

[0101] Step Sd, determining whether the lighting lamp closing proportion is not less than the preset closing proportion; if the lighting lamp proportion is greater than the preset closing proportion, step Se is executed;

[0102] Step Se, determining whether the people flow data is less than the preset people flow data; if the people flow data is less than the preset people flow data, it is determined that the air conditioning working state is a closed state;

[0103] In an embodiment, when the lighting lamp closing proportion in the office area is greater than the preset closing proportion and the people flow data is less than the preset people flow data, it is indicated that the office area in the building may be in the state of leaving work or going out, and the demand for using the air conditioner in the office area in the building during this period is low, so the air conditioner in the area needs to be turned off.

[0104] Step Sf, if the lighting lamp proportion is less than the preset closing proportion, and / or the people flow data is not less than the preset people flow data, it is determined that the air conditioning working state is an open state;

[0105] In an embodiment, when the lighting lamp closing proportion in the office area is less than the preset closing proportion, or the people flow data is not less than the preset people flow data, it is indicated that the office area may be in the state of going to work or taking a break, and the demand for using the air conditioner in the office area in the building during this period is high, so the air conditioner in the area needs to be turned on.

[0106] Step Sg, determining whether the air conditioning running state of the air conditioner and the air conditioning working state are consistent; if yes, it is determined that the air conditioner does not exist energy consumption abnormality; if no, it is determined that the air conditioner exists energy consumption abnormality.

[0107] Step S103, if there is energy consumption abnormality, it is determined that the air conditioner exists first abnormality;

[0108] Step S104, generating energy consumption prompt information according to the position information of the air conditioner and sending it to the management terminal, and adjusting the air conditioner according to the preset air conditioner adjustment strategy.

[0109] In an embodiment, the energy prompt information can be that the energy consumption of the office area a on the second floor of the A office building is abnormal, the proportion of the lighting lamp being off is b, the number of personnel is c, and verification is required. The management terminal can be a smart mobile terminal of a management personnel, such as a mobile phone, a tablet computer, or the like, or can be a computer terminal in a management room, which is not limited in the application. The management personnel can view the actual situation of the area through the camera module in the management terminal, and the management personnel can control the on-off of the air conditioner through the management terminal.

[0110] The proportion of the lighting lamp being off in each air conditioning area of the building is detected by the lighting lamp detection module, the number of personnel in each air conditioning area of the building is detected by the passenger flow detection module, and the running state of the air conditioner is calculated through the proportion of the lighting lamp being off and the number of personnel. Whether the air conditioner is in an energy consumption abnormal condition is determined by comparing the calculated running state of the air conditioner with the actual running state, and a corresponding processing mode is made for the air conditioner in the energy consumption abnormal condition in the building, so as to reduce the waste of energy of the heating and ventilation air conditioner in the building and realize intelligent energy-saving management of the heating and ventilation air conditioner in the building.

[0111] Specifically, the adjustment and execution of the air conditioner according to the preset air conditioner adjustment strategy includes two cases.

[0112] The first case is when the air conditioner type is an office area air conditioner or a public area air conditioner, step S104 specifically includes the following sub-steps (steps S1041-S1046) (not shown in the figure):

[0113] Step S1041, after the first preset time, it is judged whether the proportion of the lighting lamp is greater than the preset off proportion and whether the passenger flow data is less than the preset passenger flow data;

[0114] In an embodiment, when in the office area and the public area, there can be a situation that personnel leave but come back soon. When in this situation, the air conditioner is turned off and then turned on, which needs some time to recover to the preset temperature and reach the temperature balance state. Frequent on-off of the air conditioner consumes more energy and even affects the service life of the air conditioner. Therefore, when the electronic device judges that the office area or the public area is in the first abnormality, a first preset time is waited, which is a parameter set in advance and can be half an hour or 1 hour. After the first preset time, it is judged again whether the air conditioner in the air conditioning area is in the first abnormality.

[0115] Step S1042, if the proportion of the lighting lamp is greater than the preset off proportion and the passenger flow data is less than the preset passenger flow data, the air conditioner is controlled to be in a first energy-saving mode;

[0116] Step S1043, determining whether the lighting lamp proportion is greater than the preset closing proportion and the passenger flow data is less than the preset passenger flow data after the second preset time;

[0117] Step S1044, controlling the air conditioner to be in the second energy-saving mode if the lighting lamp proportion is greater than the preset closing proportion and the passenger flow data is less than the preset passenger flow data;

[0118] Step S1045, determining whether the lighting lamp proportion is greater than the preset closing proportion and the passenger flow data is less than the preset passenger flow data after the second preset time;

[0119] Step S1046, controlling the air conditioner to be closed if the lighting lamp proportion is greater than the preset closing proportion and the passenger flow data is less than the preset passenger flow data;

[0120] In an embodiment, after determining that the air conditioner in the air conditioner area is in the first exception for multiple times, the air conditioner is controlled to be closed, and in the process of controlling the air conditioner to be closed, the first energy-saving mode and the second energy-saving mode are gradually controlled to be turned on, thereby reducing the situation that the air conditioner is frequently turned on and off after the personnel in the office area or the public area temporarily go out, and saving the energy of the air conditioner.

[0121] In the second case, when the air conditioner type is the air conditioner in the leisure area, the air conditioner is controlled to be closed.

[0122] In an embodiment, the personnel usually located in the leisure area are temporary personnel, for example, the situation that the personnel go out and then come back is low, so when the area is determined to be in the first exception, the air conditioner is controlled to be closed.

[0123] It should be noted that the above two cases can be set according to actual conditions, and are not limited thereto.

[0124] As an optional embodiment of the embodiment of the present application, if there is no energy consumption exception in the air conditioner area, the method further includes (steps S105-S109) (not shown in the figure):

[0125] In the embodiment of the present application, the air conditioner includes a plurality of air outlet fan blade devices, and the air outlet fan blade devices are installed at the roof of each floor of the building. The environmental information further includes temperature data outside the building, humidity data and wind speed data, wherein the temperature data outside the building is collected by a temperature detection module, the humidity data is collected by a humidity detection module, and the wind speed data is collected by a wind speed collection module.

[0126] Step S105, determining the adjustment temperature of the air conditioner and the adjustment opening degree of the air outlet fan blade device according to a third preset mapping relationship based on the temperature data outside the building, the humidity data and the wind speed data and the passenger flow data in the area where the air conditioner is located;

[0127] In an embodiment, the third preset mapping relationship is a relationship between the building outdoor temperature data, the humidity data, the wind speed data, the people flow data in the area where the air conditioner is located, and the adjustment opening degree of the air conditioner adjustment temperature and the air outlet flab device, so that the temperature of the area reaches the preset temperature interval. The third preset mapping relationship can be obtained by training a neural network model according to historical data.

[0128] Step S106, controlling the air conditioner to adjust according to the adjustment temperature; and controlling the air outlet flab device to adjust according to the adjustment opening degree;

[0129] By controlling the air conditioner to adjust according to the adjustment temperature, and controlling the air outlet flab device to adjust according to the adjustment opening degree, the temperature in the air conditioner area can quickly reach the ideal temperature.

[0130] Step S107, obtaining temperature information of each air conditioner corresponding area in the building;

[0131] In an embodiment, the temperature information of the air conditioner is obtained by a temperature detection module, and the temperature is the average temperature of the air conditioner area.

[0132] Step S108, determining whether the temperature of the area is in the preset temperature interval of the corresponding area;

[0133] In an embodiment, the preset temperature interval is an ideal temperature interval for indoor comfort, which can be set. Moreover, the preset temperature interval is set according to the historical air conditioner adjustment temperature and the adjustment opening degree of the air outlet flab device. Multiple preset temperature intervals can be set, and the preset temperature intervals in different time periods in a day are different. In the comparison of the temperature with the preset temperature interval in the corresponding area, the preset temperature interval is the preset temperature interval in the same time period.

[0134] Step S109, if not in the preset temperature interval, determining whether the area is in a ventilation state; if not, performing step S110;

[0135] In an embodiment, if the temperature of the air conditioner area is not in the preset air conditioner interval, the area can be in a ventilation state, so that the temperature of the air conditioner area is unstable. Whether the area is in a ventilation state is determined by image recognition through a camera module, or by determining whether the area is in a ventilation state through a photoelectric sensor. The embodiments of the present application do not make specific limitations.

[0136] Step S110, calculating a temperature difference value according to the temperature information and the minimum value or the maximum value of the preset temperature interval;

[0137] Step S111, adjusting the adjustment temperature of the air conditioner and the adjustment opening degree of the air outlet flab device based on the temperature difference value and a preset fine adjustment regulation.

[0138] In an embodiment, if the air conditioning area is not in the preset temperature range, the temperature of the air conditioning area can be affected by other factors, so that the temperature deviates from the preset temperature range by a small amount. Therefore, the adjustment temperature of the air conditioner and the adjustment opening degree of the outlet fan device are adjusted according to the temperature difference and the preset fine adjustment adjustment rule. For example, when the temperature is 2 degrees lower than the minimum value of the preset temperature range, the adjustment temperature of the air conditioner is adjusted upward by 2 degrees, and the adjustment opening degree of the outlet fan device is adjusted to the maximum. When the temperature is 2 degrees higher than the maximum value of the preset temperature range, the adjustment temperature of the air conditioner is adjusted downward by 2 degrees, and the adjustment opening degree of the outlet fan device is adjusted to the maximum.

[0139] When the temperature difference compared with the preset temperature range in the same time period is large, there may be a possibility of hardware failure of the air conditioner. In this case, the air conditioner is still turned on, which consumes a large amount of power and causes waste of energy of the air conditioner.

[0140] Therefore, after adjusting the adjustment temperature of the air conditioner and the adjustment opening degree of the outlet fan device based on the temperature difference and the preset fine adjustment adjustment rule, the method further comprises:

[0141] The electronic device determines whether the temperature difference between the temperature of the area corresponding to the air conditioner in the building and the minimum value or the maximum value of the preset temperature range is greater than a preset temperature threshold after the air conditioner runs for a third preset time.

[0142] In an embodiment, the preset temperature threshold is a large deviation. When it is detected that the temperature difference between the temperature in the air conditioning area and the preset temperature range is greater than the preset temperature threshold, the air conditioner may have a hardware failure.

[0143] If it is greater than the preset temperature threshold, the electronic device obtains the compressor inverter voltage and the compressor inverter current, and determines whether the compressor of the air conditioner has an abnormality according to the compressor inverter voltage, the compressor inverter current, and the preset air conditioner indoor and outdoor unit parameters. If yes, it is determined that the air conditioner has a second abnormality, and running abnormal information is formed.

[0144] The electronic device obtains the outdoor fan voltage and the outdoor fan current, and determines whether the outdoor fan of the air conditioner has an abnormality according to the outdoor fan voltage, the outdoor fan current, and the preset air conditioner indoor and outdoor unit parameters. If yes, it is determined that the air conditioner has a third abnormality, and running abnormal information is formed.

[0145] According to the position information of the air conditioner and the running abnormal information, air conditioner maintenance prompt information is generated and sent to a management terminal.

[0146] By monitoring the compressor's inverter voltage, inverter current, outdoor fan current, and outdoor fan operation, the system can detect whether there are any malfunctions in the hardware of air-conditioned areas within a building experiencing abnormal temperatures. If the temperature anomaly is caused by building hardware issues, neglecting to maintain or repair air conditioners with secondary or tertiary malfunctions will result in significant energy waste during operation. By using the location and operational anomaly information of malfunctioning air conditioners, the system alerts management personnel to perform timely maintenance, thereby reducing energy waste.

[0147] like Figure 3 As shown, one implementation method for generating air conditioner maintenance prompts based on the air conditioner's location information and operational anomaly information and sending them to the management terminal specifically includes (steps S1~S4):

[0148] Step S1: The electronic device generates maintenance prompt information based on the location information of the air conditioner;

[0149] Step S2: The electronic device determines whether there are multiple maintenance prompt messages;

[0150] Step S3: If not, the maintenance prompt information is sent to the management terminal; the air conditioner can be turned off before the electronic device sends the maintenance prompt information to the management terminal, and the management personnel can perform maintenance on the air conditioner according to the maintenance prompt information.

[0151] Step S4: If yes, then determine the corresponding maintenance priority sequence according to the air conditioner type corresponding to each maintenance prompt message, and send each maintenance prompt message to the management terminal according to the maintenance priority sequence; wherein, the maintenance priority corresponding to the office area air conditioner type is higher than the maintenance priority corresponding to the public area air conditioner type, and the maintenance priority corresponding to the public area air conditioner type is higher than the maintenance priority corresponding to the leisure area air conditioner.

[0152] In one implementation, when it is determined that there is a second or third anomaly in multiple air-conditioned areas, the electronic device first turns off the air conditioner. Then, the electronic device determines the maintenance priority list according to the air conditioner type of the abnormal air conditioner and sends maintenance prompt information to the management terminal according to the priority sequence, so that the management personnel can perform maintenance on the air conditioner with the second or third anomaly according to the priority sequence.

[0153] Based on the different priorities of air conditioning usage needs corresponding to different types of air conditioners, the corresponding maintenance priorities are reasonably arranged. The maintenance priority of air conditioners in office areas is set to the highest, followed by air conditioners in public areas, and air conditioners in leisure areas are set to the lowest. Thus, the air conditioners with higher maintenance priority are arranged for repair first according to their urgency.

[0154] It should be noted that the maintenance priority of air conditioner type is based on the usage time of the air conditioner. Generally, the usage time of air conditioners in office areas is longer than that in public areas, and the usage time of air conditioners in public areas is longer than that in leisure areas. The maintenance priority is set according to the actual usage of air conditioners in the building and is not limited to the maintenance priority specified above.

[0155] As a further implementation of this application, after determining the corresponding maintenance priority sequence in step S4, the method further includes (steps S5-S8) (not shown in the figures):

[0156] Step S5: Determine whether there are multiple air conditioners with the same maintenance priority. If so, obtain the air conditioner usage information of each air conditioner with the same maintenance priority in the previous time period.

[0157] Step S6: Based on preset calculation rules, calculate the usage priority index corresponding to each air conditioner with the same maintenance priority according to the air conditioner usage information;

[0158] Step S7: Sort the air conditioners according to their usage priority indices for the same maintenance priority to obtain the maintenance sub-priorities for each air conditioner with the same maintenance priority; wherein, the higher the usage priority index of the air conditioner, the higher the corresponding maintenance sub-priority.

[0159] In the above implementation, since the maintenance priority is the same for the same type of air conditioner, when there are multiple abnormal air conditioners of the same type, the corresponding usage priority index is calculated based on the air conditioner usage information of each air conditioner in the previous historical period. The air conditioner usage information includes the air conditioner usage time and the flow of people in the area where the air conditioner is located. Different weights are assigned to the air conditioner usage time and the flow of people in the area where the air conditioner is located. The usage priority is calculated based on the weights. The higher the usage priority index, the higher the corresponding maintenance sub-priority is set. Thus, maintenance is arranged for each air conditioner with the same maintenance priority according to the maintenance sub-priority. This improves the experience of people in the building and ensures that the air conditioner maintenance work is carried out in an orderly manner.
