[0025] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0026] At the same time, it should be understood that, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn according to actual scale.

[0027] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0029] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0031] Most related technologies employ a fixed and singular self-test mode for air conditioner self-testing, resulting in a poor user experience and potential energy waste. Furthermore, after the self-test function identifies a fault in the air conditioner, cumbersome procedures such as manual fault reporting and contacting repair personnel are required before repairs can be carried out, leading to low efficiency in air conditioner operation and maintenance.

[0032] In view of this, this disclosure proposes an air conditioner self-test method, device, and system that can support multiple air conditioner self-test modes, improving user experience. At the same time, by outputting precise fault indication information based on the fault type, it facilitates timely fault location and handling by maintenance personnel, improving maintenance efficiency.

[0033] Figure 1 This is a schematic flowchart illustrating an air conditioner self-test method according to some embodiments of the present disclosure. Figure 1 As shown, the air conditioner self-test method includes steps S101 to S103.

[0034] In step S101, the self-test mode of the air conditioner to be tested is determined from multiple self-test modes.

[0035] In some embodiments, the air conditioning self-test method is performed by an air conditioning self-test device. In some examples, the air conditioning self-test device is a programmable logic controller or a module within a programmable logic controller.

[0036] In some embodiments, the component parameters detected by the various self-test modes are different.

[0037] In some embodiments, the component parameters detected by each of the multiple self-test modes include one or more parameters of the air supply fan, return fan, fire damper, antifreeze switch, fresh air valve, and mixing valve of the air conditioner under test.

[0038] In some embodiments, the self-test mode of the air conditioner to be tested is determined from multiple self-test modes according to the user's mode setting instructions.

[0039] In some examples, users input mode setting commands through a mode setting module. For instance, the mode setting module could be a button on an air conditioner remote control or a visual component on the air conditioner management application interface of a mobile device.

[0040] In some examples, the self-test mode of the air conditioner under test includes a first self-test mode and a second self-test mode. The first self-test mode tests more component parameters, providing a more comprehensive test, but it takes longer; the second self-test mode tests fewer component parameters, but it takes less time. For example, when the user selects the first self-test mode, the parameters of the air conditioner's supply fan, return air fan, fire damper, anti-freeze switch, fresh air valve, and mixing valve are tested; when the user selects the second self-test mode, the parameters of the air conditioner's supply fan and return air fan are tested.

[0041] In some examples, the self-test mode of the air conditioner under test includes not only the first self-test mode and the second self-test mode, but also a custom self-test mode. After the user selects the custom self-test mode, a component parameter setting page is displayed. The user can set the component parameters to be tested on this page. This allows for flexible customization of the component parameters to be tested according to user needs.

[0042] In some examples, the self-test mode of the air conditioner under test includes not only the first self-test mode and the second self-test mode, but also an intelligent self-test mode. After the user selects the intelligent self-test mode, the air conditioner self-test device acquires information such as the season and the environment in which the air conditioner is located, and automatically determines the parameters of the components to be tested based on this information. For example, the air conditioner self-test device can acquire information such as the current season and ambient temperature through networking or other means, and set the parameters of the components to be tested accordingly. For instance, if it is determined that the current season is summer and the ambient temperature is high, the parameters of components such as the air conditioner's fire damper are tested, but the parameters of the air conditioner's anti-freeze switch are not tested; if it is determined that the current season is winter and the temperature is low, the parameters of the air conditioner's anti-freeze switch are tested, but the parameters of the air conditioner's fire damper are not tested.

[0043] In some embodiments, in step S101, the self-test mode of the air conditioner to be tested is determined from multiple self-test modes in the following manner: obtaining the type information of the air conditioner to be tested and / or the environmental information of the air conditioner to be tested; determining the self-test mode of the air conditioner to be tested from multiple self-test modes based on the type information of the air conditioner to be tested and / or the environmental information of the air conditioner to be tested.

[0044] In some examples, in step S101, the type information of the air conditioner to be tested is obtained, and the self-test mode of the air conditioner to be tested is determined based on the type information of the air conditioner to be tested and the mapping relationship between the type of air conditioner and the self-test mode. Optionally, in these examples, a set threshold for component parameters can also be selected based on the type information of the air conditioner to be tested, so as to compare it with the values ​​of the detected component parameters during the air conditioner self-test, which helps to improve the accuracy and applicability of the air conditioner self-test.

[0045] For example, if the type information of the air conditioner to be tested indicates that it is Type 1, and the corresponding self-test mode is Type 1, then the air conditioner will be tested according to Type 1 self-test mode. If the type information of the air conditioner to be tested indicates that it is Type 2, and the corresponding self-test mode is Type 2, then the air conditioner will be tested according to Type 2 self-test mode. Type 1 and Type 2 can be determined based on the actual air conditioner's classification method. For example, Type 1 might be a wall-mounted air conditioner, and Type 2 might be a floor-standing air conditioner. Or, Type 1 might be a wall-mounted air conditioner with model number XX1, and Type 2 might be a wall-mounted air conditioner with model number XX2.

[0046] In this embodiment of the disclosure, the above processing enables a more targeted self-test mode to be adopted according to the type of air conditioner. This allows for meeting the self-testing needs of various types of air conditioners while improving the flexibility and accuracy of air conditioner self-testing and reducing energy waste caused by unnecessary component parameter testing.

[0047] In some examples, in step S101, the environmental information of the air conditioner under test is obtained, and the self-test mode of the air conditioner under test is determined based on the environmental information of the air conditioner under test and the mapping relationship between the air conditioner's environment and its self-test mode. The environmental information includes ambient temperature information.

[0048] For example, if the environmental information of the air conditioner under test indicates that the temperature is high and the self-test mode corresponding to that temperature is the first self-test mode, the air conditioner will be tested according to the first self-test mode; if the environmental information of the air conditioner under test indicates that the temperature is low and the self-test mode corresponding to that temperature is the second self-test mode, the air conditioner will be tested according to the second self-test mode.

[0049] In this embodiment of the disclosure, through the above processing, a more targeted self-test mode can be adopted according to the environmental information of the air conditioner, thereby meeting the self-test requirements of the air conditioner in various environments, improving the flexibility and accuracy of the air conditioner self-test, and reducing energy waste caused by unnecessary component parameter testing.

[0050] In some examples, in step S101, the type information of the air conditioner to be tested and the environmental information of the air conditioner to be tested are obtained. Based on the type of the air conditioner to be tested and the environmental information, as well as the mapping relationship between the type of the air conditioner, the environment and the self-test mode, the self-test mode of the air conditioner to be tested is determined.

[0051] In some examples, the type information of the air conditioner under test and the environmental information of the air conditioner under test are obtained as follows: the type information of the air conditioner under test is obtained from the air conditioner management system; the environmental information of the air conditioner under test is received from an environmental detection sensor. The environmental information includes ambient temperature information, and the environmental detection sensor includes a temperature sensor.

[0052] For example, when the type information of the air conditioner to be tested indicates that the air conditioner is of type 1 and the environmental information indicates that the temperature is high, the first self-test mode is used; when the type information of the air conditioner to be tested indicates that the air conditioner is of type 1 and the environmental information indicates that the temperature is low, the second self-test mode is used; when the type information of the air conditioner to be tested indicates that the air conditioner is of type 2 and the environmental information indicates that the temperature is high, the third self-test mode is used; and when the type information of the air conditioner to be tested indicates that the air conditioner is of type 2 and the environmental information indicates that the temperature is low, the fourth self-test mode is used.

[0053] In this embodiment of the disclosure, through the above processing, a more targeted self-test mode can be adopted based on the type information of the air conditioner and the environmental information of the air conditioner. This can improve the flexibility and accuracy of the air conditioner self-test while meeting the self-test requirements of various air conditioner types and environments, and reduce energy waste caused by unnecessary component parameter testing.

[0054] In step S102, the parameters of the component to be tested, corresponding to the self-test mode of the air conditioner to be tested, are tested.

[0055] For example, when the self-test mode of the air conditioner under test is the first self-test mode, the parameters of the component under test corresponding to the first self-test mode are tested; when the self-test mode of the air conditioner under test is the second self-test mode, the parameters of the component under test corresponding to the second self-test mode are tested. The parameters of the component under test are different for each self-test mode.

[0056] In step S103, if the detection result indicates that the air conditioner under test has a fault, a fault prompt message is output according to the type of fault.

[0057] For example, when the test result indicates that the supply fan is faulty, a prompt message indicating that the supply fan is faulty is output; when the test result indicates that the return fan is faulty, a prompt message indicating that the return fan is faulty is output.

[0058] In some examples, fault messages are output in the following ways: by presenting fault messages with sound, images, or lights, or by sending fault messages to the terminal devices of the maintenance personnel.

[0059] In this embodiment, the above steps support multiple air conditioner self-test modes, improving user experience. Simultaneously, by outputting precise fault indication information based on the fault type, maintenance personnel can promptly locate and handle faults, improving maintenance efficiency.

[0060] Figure 2 This is a schematic flowchart illustrating an air conditioner self-test method according to some embodiments of the present disclosure. Figure 2 As shown, the air conditioner self-test method includes steps S201 to S209.

[0061] In step S201, the status parameters of the supply fan and return fan are detected.

[0062] In some embodiments, after determining that the self-test mode of the air conditioner to be tested is the first self-test mode, steps S201 to S209 are executed. The parameters of the component to be tested corresponding to the first self-test mode are more numerous than those corresponding to the second self-test mode.

[0063] In some embodiments, in step S201, it is detected whether the supply fan and return fan are in "automatic" or "manual" mode. If the supply fan is in "manual" mode, the status parameter is confirmed to be normal; if the supply fan is in "automatic" mode, the status parameter is confirmed to be abnormal. If the return fan is in "manual" mode, the status parameter is confirmed to be normal; if the return fan is in "automatic" mode, the status parameter is confirmed to be abnormal. Optionally, in some of the above embodiments, when the supply fan is in "manual" mode, the first variable is set to 0; when the supply fan is in "automatic" mode, the first variable is set to 1. When the return fan is in "manual" mode, the second variable is set to 0; when the return fan is in "automatic" mode, the second variable is set to 1.

[0064] In some embodiments, in step S201, the equipment status of the supply fan and the return fan is also detected. If the supply fan is in a "non-fault" state, the status parameter is confirmed to be normal; if the supply fan is in a "fault" state, the status parameter is confirmed to be abnormal. If the return fan is in a "non-fault" state, the status parameter is confirmed to be normal; if the return fan is in a "fault" state, the status parameter is confirmed to be abnormal. Optionally, in some of the above embodiments, when the supply fan is in a "non-fault" state, the third variable is set to 0; when the supply fan is in a "fault" state, the third variable is set to 1. When the return fan is in a "non-fault" state, the fourth variable is set to 0; when the return fan is in a "fault" state, the fourth variable is set to 1.

[0065] In some embodiments, step S201 also detects the operating current of the supply fan and the return fan. For example, current sensors are installed at the output terminals of the frequency converters of the supply fan and the return fan, respectively, and the current sensors are connected to a programmable logic controller (PLC). For example, the positive terminal of the current sensor is connected to a voltage (such as a 24V DC voltage), and the negative terminal of the current sensor outputs current. The current is measured in real time by changing the analog output current. The PLC program is equipped with an analog-to-digital conversion function to collect the current value in real time.

[0066] In the above embodiments, if the operating current of the blower is within the set current range, the status parameter is confirmed to be normal; if the operating current of the blower exceeds the set current range, the status parameter is confirmed to be abnormal. Similarly, if the operating current of the return air blower is within the set current range, the status parameter is confirmed to be normal; if the operating current of the return air blower exceeds the set current range, the status parameter is confirmed to be abnormal. Optionally, in the above embodiments, when the operating current of the blower is within the set current range, the fifth variable is output as 0; when the operating current of the blower exceeds the set current range, the fifth variable is output as 1. When the operating current of the return air blower is within the set current range, the sixth variable is output as 0; when the operating current of the blower exceeds the set current range, the sixth variable is output as 1.

[0067] In step S202, the status parameters of the air conditioning unit are detected.

[0068] In some embodiments, in step S202, it is detected whether the air conditioning unit is in an "emergency stop" state or a "non-emergency stop" state. If the air conditioning unit is in a "non-emergency stop" state, the state parameter is confirmed to be normal; if the air conditioning unit is in an "emergency stop" state, the state parameter is confirmed to be abnormal. Optionally, in some of the above embodiments, if the air conditioning unit is in a "non-emergency stop" state, the seventh variable is set to 0; if the air conditioning unit is in an "emergency stop" state, the seventh variable is set to 1.

[0069] In some embodiments, in step S202, it is further detected whether the air conditioning unit is in a "fire alarm" state or a "non-fire alarm" state. If the air conditioning unit is in a "non-fire alarm" state, the state parameter is confirmed to be normal; if the air conditioning unit is in a "fire alarm" state, the state parameter is confirmed to be abnormal. Optionally, in some of the above embodiments, if the air conditioning unit is in a "non-fire alarm" state, the eighth variable is set to 0; if the air conditioning unit is in a "fire alarm" state, the eighth variable is set to 1.

[0070] In some embodiments, in step S202, it is also detected whether the air conditioning unit is in a maintenance state or a non-maintenance state. When the air conditioning unit is in a non-maintenance state, the status parameter is confirmed to be normal; when the air conditioning unit is in a maintenance state, the status parameter is confirmed to be abnormal. Optionally, in some of the above embodiments, if the air conditioning unit is in a "non-maintenance" state, the ninth variable is set to 0; if the air conditioning unit is in a "maintenance" state, the ninth variable is set to 1.

[0071] In step S203, the status parameters of the fire damper are detected.

[0072] In some embodiments, in step S203, it is detected whether the fire damper is in an "alarm" state or a "non-alarm" state. If the fire damper is in a "non-alarm" state, the state parameter is confirmed to be normal; if the fire damper is in an "alarm" state, the state parameter is confirmed to be abnormal. Optionally, in the above embodiments, if the fire damper is in a "non-alarm" state, the tenth variable is set to 0; if the fire damper is in an "alarm" state, the tenth variable is set to 1.

[0073] In step S204, the opening degree of the fresh air valve and the mixing air valve is detected.

[0074] In some embodiments, in step S204, it is checked whether the sum of the openings of the fresh air valve and the mixing valve of the air conditioner is greater than or equal to a set value. If the sum of the openings of the fresh air valve and the mixing valve is greater than or equal to the set value, the status parameter is confirmed to be normal; if the sum of the openings of the fresh air valve and the mixing valve is less than the set value, the status parameter is confirmed to be abnormal. Optionally, in the above embodiments, if the sum of the openings of the fresh air valve and the mixing valve is greater than or equal to the set value, the eleventh variable is output as 0; if the sum of the openings of the fresh air valve and the mixing valve is less than the set value, the eleventh variable is output as 1. Through the above detection, it is possible to ensure that the fresh air supply and local exhaust volume in the working area corresponding to the air conditioner are equal as much as possible, so as not to generate negative pressure indoors. The set value can be determined based on experience, for example, let the set value be equal to 80.

[0075] In step S205, the status parameters of the antifreeze switch are detected.

[0076] In some embodiments, in step S205, it is detected whether the antifreeze switch of the air conditioner is in an "active" or "deactivated" state. If the antifreeze switch is in a "deactivated" state, the state parameter is confirmed to be normal; if the antifreeze switch is in an "active" state due to factors such as the evaporator temperature being too low, the state parameter is confirmed to be abnormal. Optionally, in the above embodiments, if the antifreeze switch is in a "deactivated" state, the twelfth variable is output as 0; if the antifreeze switch is in an "active" state, the twelfth variable is output as 1.

[0077] In step S206, it is determined whether the above parameters indicate the presence of a fault.

[0078] In some embodiments, if the status parameters detected through steps S201 to S205 are abnormal, a fault is confirmed; if the status parameters detected through steps S201 to S205 are all normal, a fault is confirmed.

[0079] In some embodiments, the thirteenth variable controls the operating output value of the entire air conditioning system. When the status parameters detected by steps S201 to S205 indicate that the air conditioner is not faulty, the output of the thirteenth variable is set to 1; otherwise, the output of the thirteenth variable is set to 0.

[0080] If the above parameters indicate a fault, proceed to steps S207 and S208; otherwise, proceed to step S209.

[0081] In step S207, a fault prompt message is output according to the type of fault.

[0082] In some embodiments, the type of fault is determined based on the presence of abnormal state parameters. For example, when the blower is in "automatic" mode, the fault type is "blower operating mode setting error". For example, when the antifreeze switch is in an active state, the fault type is "antifreeze switch status abnormal".

[0083] In some embodiments, fault prompts may be presented by means of sound, images, or lights, or the fault prompts may be sent to the terminal devices of the maintenance personnel.

[0084] In step S208, a maintenance work order is generated according to the type of fault and sent to the maintenance terminal.

[0085] In some embodiments, a maintenance work order is automatically generated based on the type of fault and a pre-set work order template; the target maintenance personnel is determined from multiple maintenance personnel based on the mapping relationship between fault type and maintenance personnel, and the maintenance work order is sent to the maintenance terminal corresponding to the target maintenance personnel.

[0086] Steps S207 and S208 link air conditioner self-checking and maintenance management, improving the timeliness and efficiency of air conditioner maintenance. Furthermore, by pre-setting work order templates and dynamically generating maintenance work orders based on fault types and templates, the efficiency of work order generation is improved, further enhancing the timeliness and efficiency of air conditioner maintenance. By pre-setting the mapping relationship between fault types and maintenance personnel, and accordingly identifying target maintenance personnel, more suitable personnel are found for air conditioner maintenance, further improving the efficiency of air conditioner maintenance.

[0087] In step S209, the air conditioner to be tested is put into operation.

[0088] In this embodiment, the above steps implement a self-test function during air conditioner startup. By performing self-tests on key parameters during the air conditioning unit startup process, the safety and stability of the air conditioner operation are improved. Furthermore, by outputting precise fault prompts based on the fault type and generating maintenance work orders, maintenance personnel can promptly locate and handle faults, improving maintenance efficiency. In addition, the above method can support multiple air conditioner self-test modes, improving the user experience.

[0089] Figure 3This is a block diagram illustrating an air conditioner self-test device according to some embodiments of the present disclosure. Figure 3 As shown, the air conditioner self-test device 30 includes a determination module 301, a detection module 302, and a fault handling module 303.

[0093] In some examples, the detection module 302 obtains the type information of the air conditioner to be tested from the air conditioner management system; receives the environmental information of the air conditioner to be tested from the environmental detection sensor; and determines the self-test mode of the air conditioner to be tested from multiple self-test modes based on the type information of the air conditioner to be tested and the environmental information of the air conditioner to be tested. The environmental information includes the ambient temperature information.

[0094] In some examples, the detection module 302 determines the self-test mode of the air conditioner to be tested from multiple self-test modes based on the mapping relationship between air conditioner type, air conditioner environment and self-test mode.

[0095] In some embodiments, the detection module 302 is configured to determine the self-test mode of the air conditioner to be tested from a variety of self-test modes according to the user's mode setting instructions.

[0096] The fault handling module 303 is configured to output fault prompt information according to the type of fault when the detection result indicates that the air conditioner under test has a fault.

[0097] In some embodiments, the fault handling module 303 is further configured to generate a maintenance work order based on the type of fault and send the maintenance work order to the operation and maintenance terminal.

[0098] In some embodiments, the air conditioner self-test device further includes a mode switching module configured to put the air conditioner under test into operation if the test result indicates that the air conditioner under test has no fault.

[0099] In this embodiment, the above device can support multiple air conditioner self-test modes, improving user experience. At the same time, by outputting precise fault indication information based on the fault type, it facilitates timely fault location and handling by maintenance personnel, improving maintenance efficiency.
