Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to a method for scheduling faults in wired controllers for temperature detection, wired controllers, devices, and storage media. Background Technology

[0002] As products are upgraded, multi-split air conditioner controllers are also being upgraded, incorporating temperature and humidity sensors within the unit. Because these sensors are exposed to the elements through ventilation holes, they cannot meet moisture-proof requirements. During new home renovations, sometimes the controller is installed before painting, causing paint to enter the controller's ventilation holes and adhere to the temperature and humidity sensors. This paint can corrode the sensors, leading to malfunction. Alternatively, if the controller is installed in a humid environment, the sensors may also corrode, causing them to fail and affecting air conditioner operation. Furthermore, since the temperature and humidity sensors are typically soldered directly to the controller's main board, repairs are difficult, often requiring replacement of the entire controller. This wastes the replaced controller, especially for higher-cost color-screen controllers, leading to even greater cost savings. It is evident that in the existing technology, the temperature and humidity sensors of the air conditioner controller may fail due to corrosion from building materials or humid environments, thus affecting the normal operation of the air conditioner. In addition, the controller may be directly replaced due to the fact that the temperature and humidity sensors in the controller are damaged but cannot be disassembled, resulting in wasted costs. Summary of the Invention

[0003] This application provides a method for scheduling faults in temperature detection of wired controllers, a wired controller, an equipment, and a storage medium to solve the problems of low reliability caused by temperature and humidity sensor failure due to installation environment or material corrosion in the prior art, and the waste of resources caused by direct replacement of the wired controller due to the inconvenience of disassembling and assembling the temperature and humidity sensor and the wired controller motherboard due to the connection method between the temperature and humidity sensor and the wired controller motherboard.

[0004] According to a first aspect of the embodiments of this application, this application provides a method for scheduling faults in a wired controller with temperature detection, wherein the wired controller includes a wired controller motherboard and a temperature and humidity sensor connected via an FPC cable, and the method includes:

[0005] Acquire communication status data and humidity start data between the wired controller motherboard and the temperature and humidity sensor;

[0006] Based on the communication status data and the humidity activation data, perform fault analysis on the temperature and humidity sensor to obtain the sensor status;

[0007] Based on the sensor status, the temperature sensor data of the indoor unit return air vent temperature sensor controlled by the wired controller is obtained, and the temperature sensor data is used to determine whether the indoor unit return air vent temperature sensor is faulty. The temperature sensor data includes return air vent temperature data.

[0008] If the temperature sensor at the indoor unit's return air vent is functioning correctly, the return air vent temperature data will be corrected in heating mode to obtain an auxiliary control temperature. This auxiliary control temperature will then be switched to the indoor ambient temperature for unit temperature control. Alternatively, in non-heating mode, the return air vent temperature data will be used as the indoor ambient temperature for unit temperature control.

[0009] Optionally, the step of performing temperature and humidity sensor fault analysis based on the communication status data and the humidity activation data to obtain the sensor status includes:

[0010] The communication status is determined based on the communication status data between the wired controller motherboard and the temperature and humidity sensor.

[0011] If the communication status is abnormal, determine whether to enable humidity setting control based on the humidity start data, and obtain the sensor status based on whether the humidity setting control is enabled. The sensor status includes temperature and humidity sensor failure and temperature and humidity sensor no failure.

[0012] Optionally, the communication status determination based on the communication status data between the wired controller motherboard and the temperature and humidity sensor includes:

[0013] Based on the communication status data, determine whether there is at least one of the following states: no communication response, failure to read temperature and humidity data, or failure to verify data reading.

[0014] If it exists, it is determined that the communication status is abnormal, and the humidity setting control is determined based on the humidity start data.

[0015] If it does not exist, it is determined that there is no abnormality in the communication status, and the temperature and humidity data detected by the temperature and humidity sensor is read to control the operation of the unit.

[0016] Optionally, the step of determining whether to enable humidity setting control based on the humidity activation data, and obtaining the sensor status based on whether the humidity setting control is enabled, includes:

[0017] Based on the humidity start-up data, determine whether to enable the humidity setting control;

[0018] If the humidity setting control is enabled, it is determined that the temperature and humidity sensor is faulty, and the temperature and humidity sensor fault is reported and a fault prompt is given.

[0019] If the humidity setting control is not enabled, no temperature and humidity sensor fault will be reported.

[0020] Optionally, the step of acquiring the temperature sensor data of the indoor unit's return air vent temperature sensor controlled by the wired controller based on the sensor status, and determining whether the indoor unit's return air vent temperature sensor is faulty based on the temperature sensor data, includes:

[0021] If the temperature and humidity sensor malfunction is not reported, then the return air vent temperature data collected by the indoor unit's return air vent temperature sensor is read.

[0022] The return air vent temperature data is compared with a preset temperature threshold to determine whether the temperature difference exceeds the set temperature difference threshold.

[0023] If the temperature difference exceeds the set temperature difference threshold, the indoor unit's return air inlet temperature sensor is determined to be faulty, and a fault report and fault prompt are issued.

[0024] If the temperature difference does not exceed the set temperature difference threshold, it is determined that the indoor unit return air temperature sensor is fault-free.

[0025] Optionally, the step of correcting the return air vent temperature data in heating mode to obtain an auxiliary control temperature, and then switching the auxiliary control temperature to the indoor ambient temperature for unit temperature control, includes:

[0026] If the temperature sensor at the indoor unit's return air vent is fault-free, then obtain the number of indoor unit control consoles controlled by the wired controller and the unit's operating mode.

[0027] If the number of indoor unit control consoles controlled by the wired controller is at least one and the unit is running in non-heating mode, then the return air vent temperature data is read and used as the indoor ambient temperature for unit temperature control.

[0028] If the number of indoor unit consoles controlled by the wired controller is one and the unit is running in heating mode, the return air outlet temperature data is read, the return air outlet temperature data is corrected based on the temperature correction value to obtain the auxiliary scheduling temperature, and the auxiliary scheduling temperature is switched to the indoor ambient temperature for unit temperature control.

[0029] If the number of indoor unit control consoles controlled by the wired controller is multiple and the unit is running in heating mode, the indoor unit return air vent temperature reference value is calculated based on the return air vent temperature data of each indoor unit, the indoor unit return air vent temperature reference value is corrected based on the temperature correction value to obtain the auxiliary scheduling temperature, and the auxiliary scheduling temperature is switched to the indoor ambient temperature for unit temperature control.

[0030] If the indoor unit is controlled by a single wired controller and the unit is operating in non-heating mode, the return air vent temperature data is read and used as the indoor ambient temperature for unit temperature control.

[0031] If the number of indoor unit control consoles controlled by the wired controller is multiple and the unit is running in non-heating mode, then the reference value of the indoor unit return air vent temperature is calculated based on the return air vent temperature data of each indoor unit and used as the indoor ambient temperature for unit temperature control.

[0032] According to a second aspect of the embodiments of this application, this application provides a wired controller applicable to the wired controller temperature detection fault scheduling method described in the first aspect. The wired controller includes a wired controller motherboard and a temperature and humidity sensor. The wired controller motherboard is provided with a ribbon cable connector terminal, which is connected to one end of an FPC ribbon cable, and the other end of the FPC ribbon cable is connected to the temperature sensor.

[0033] Optionally, the wired controller further includes at least one ventilation hole, a housing, and a sealing structure partition plate. The ventilation hole is located on the housing and close to the temperature and humidity sensor. The sealing structure partition plate is located inside the ventilation hole, dividing the inner cavity of the housing into a sealed area and a ventilation area. The main board of the wired controller is located in the sealed area, and the temperature and humidity sensor and the ventilation hole are located in the ventilation area.

[0034] According to a third aspect of the embodiments of this application, this application provides an electronic device, including a memory, a processor, a communication interface, and a communication bus. The memory stores a computer program that can run on the processor. The memory and the processor communicate through the communication bus and the communication interface. When the processor executes the computer program, it implements the steps of the wired controller temperature detection fault scheduling method described in the first aspect.

[0035] According to a fourth aspect of the embodiments of this application, this application provides a storage medium having processor-executable non-volatile program code, the program code causing the processor to perform the steps of the wired controller temperature detection fault scheduling method described in the first aspect.

[0036] Compared with related technologies, the technical solutions provided in this application have the following advantages:

[0037] In the wired controller of this application, the temperature and humidity sensor is connected to the main board of the wired controller via an FPC cable to complete the circuit conduction, which facilitates disassembly and maintenance without the need to replace the entire wired controller. The temperature and humidity sensor can be directly replaced by unplugging the FPC cable, which reduces waste and saves costs. Fault analysis of the temperature and humidity sensor is performed based on communication status data and humidity start-up data, which is more conducive to accurately determining the actual status of the temperature and humidity sensor. In the event that the temperature and humidity sensor fails to detect temperature due to installation environment or material corrosion, the return air vent temperature data of the indoor unit's return air vent temperature sensor controlled by the wired controller is obtained. In heating mode, the return air vent temperature data is corrected, and the corrected auxiliary scheduling temperature is used as the indoor ambient temperature of the temperature and humidity sensor. The unit will use the auxiliary scheduling temperature as the temperature detected by the temperature and humidity sensor for unit control, realizing temperature scheduling even when the temperature and humidity sensor fails to detect temperature. This maximizes the use of the detected temperatures of other temperature sensors on the unit as the indoor ambient temperature for unit control, ensuring normal user operation of the product, improving unit reliability, and reducing maintenance costs.

[0048] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] To address the problems mentioned in the background art, according to one aspect of the embodiments of this application, an embodiment of a wired controller temperature detection fault scheduling method is provided.

[0050] like Figure 1 As shown, the above-mentioned wired controller temperature detection fault scheduling method can be applied to, for example... Figure 1 The hardware environment shown is described. The system architecture 100 of the hardware environment includes a terminal device 101 and a server 103.

[0052] It should be noted that the wired controller temperature detection fault scheduling method provided in this application embodiment is generally executed by a server and / or terminal device, and correspondingly, the wired controller temperature detection fault scheduling device is generally installed in the server / terminal device. Furthermore, it should be understood that... Figure 1 The number of terminal devices, networks, and servers shown is merely illustrative. Depending on implementation needs, any number of terminal devices, networks, and servers can be included.

[0053] like Figure 2 As shown, Figure 2 A flowchart of a wired controller temperature detection fault scheduling method provided in an embodiment of the present invention. Taking the wired controller temperature detection fault scheduling method being executed by a server as an example, the wired controller temperature detection fault scheduling method includes the following steps:

[0054] Step S202: Obtain the communication status data and humidity start data between the wired controller motherboard and the temperature and humidity sensor.

[0055] The wired controller temperature detection fault scheduling method provided in this embodiment is applicable to environments where the temperature sensor of the wired controller in an air conditioning unit detects temperature. The applicable wired controller includes a wired controller motherboard and a temperature and humidity sensor connected via an FPC cable. The control module of the air conditioning unit is connected to the wired controller, and the wired controller can control the temperature and humidity sensor and at least one indoor air conditioning unit through the wired controller motherboard. The temperature and humidity sensor model may include, but is not limited to, DHT11, AHT20, etc.

[0056] The wired controller's main board and the temperature and humidity sensor are connected via an FPC (Flexible Printed Circuit) cable. After the wired controller is powered on, it can communicate based on the IIC (Inter-Integrated Circuit) bus. The wired controller's main board or the air conditioning unit can monitor the communication status between the main board and the temperature and humidity sensor in real time or at regular intervals, acquiring communication status data. This communication status data indicates whether the communication between the main board and the temperature and humidity sensor is normal. For example, if there is no response during IIC communication acquisition, the communication status data will show as communication fault data, providing feedback on the specific fault type and fault time. Alternatively, the temperature and humidity sensor and the main board can also communicate via the I2C (Inter-Integrated Circuit) protocol.

[0057] In some embodiments, the communication status data between the wired controller motherboard and the temperature and humidity sensor can be acquired multiple times within a certain period of time. If the same abnormal result is obtained several times in a row, it is determined to be a communication failure. The abnormal result may include no response to IIC communication, failure to read temperature and humidity data, failure to verify temperature and humidity data, etc.

[0058] In some embodiments, the humidity start-up data mentioned above can be data generated after user-side startup, for user-configured functions. Users can enable / disable the humidity control setting function of the temperature and humidity sensor in the wired controller of the air conditioning unit. When enabled, the temperature and humidity sensor can monitor the indoor humidity, and the humidity start-up data collected by the air conditioning unit or wired controller from the user will indicate that humidity monitoring is enabled; when disabled, indoor humidity is not detected, and the humidity start-up data collected by the air conditioning unit or wired controller from the user will indicate that humidity monitoring is disabled.

[0059] Step S204: Perform a fault analysis of the temperature and humidity sensor based on the communication status data and the humidity start-up data to obtain the sensor status.

[0060] In this embodiment, based on the acquired communication status data, after analyzing the communication status between the wired controller motherboard and the temperature and humidity sensor, the fault status of the temperature and humidity sensor can be further analyzed in conjunction with the humidity start-up data to obtain the sensor status and determine whether the temperature and humidity sensor is faulty, so as to carry out targeted control for faulty or non-faulty but temperature detection failure situations.

[0061] Step S206: Based on the sensor status, acquire the temperature sensor data of the indoor unit return air vent temperature sensor controlled by the wired controller, and determine whether the indoor unit return air vent temperature sensor is faulty based on the temperature sensor data. The temperature sensor data includes return air vent temperature data.

[0062] In this embodiment, when the temperature and humidity sensor cannot control the temperature, but the sensor status indicates that the sensor is not faulty, the return air temperature data collected by the return air vent temperature sensor on the indoor unit can still be used for normal temperature control of the air conditioning unit. Therefore, the temperature sensor data of the indoor unit's return air vent temperature sensor can be read, and the sensor data can be combined to determine whether the indoor unit's return air vent temperature sensor is faulty. The temperature sensor data includes not only return air vent temperature data but also temperature sensor status data, such as whether the temperature sensor is collecting temperature data normally or whether temperature collection has failed.

[0063] Step S208: If the temperature sensor at the indoor unit's return air vent is fault-free, the temperature data at the return air vent is corrected in heating mode to obtain an auxiliary scheduling temperature, and the auxiliary scheduling temperature is switched to the indoor ambient temperature for unit temperature control, or the temperature data at the return air vent is used as the indoor ambient temperature for unit temperature control in non-heating mode.

[0064] In this embodiment, when the temperature sensor at the indoor unit's return air vent is determined to be fault-free based on the sensor data, the unit's operating mode can be determined first. Because the temperature difference between the return air vent temperature and the indoor ambient temperature varies depending on the operating mode, the temperature control method also differs. For heating mode, because heat around the return air vent of ducted units and similar units does not dissipate easily, the return air vent temperature will be relatively higher than the indoor ambient temperature. Therefore, the acquired return air vent temperature data needs to be corrected to obtain an auxiliary control temperature, which is then sent to the air conditioning unit as the indoor ambient temperature for temperature control. This auxiliary control temperature serves as a supplement to the indoor ambient temperature that the temperature and humidity sensor should collect. It compensates for the failure of the temperature and humidity sensor due to corrosion from building materials or humid environments, ensuring the air conditioning unit continues to operate normally, improving system reliability, ensuring users can continue to use the air conditioning product normally, and eliminating the need for maintenance, thus saving costs.

[0065] In other embodiments, in non-heating mode, the return air vent temperature data is closer to the indoor ambient temperature. Therefore, the acquired return air vent temperature data can be directly sent to the air conditioning unit as indoor ambient temperature data for temperature control to meet customer needs. The non-heating mode can be cooling mode, sleep mode, etc.

[0066] In this embodiment of the invention, the temperature and humidity sensor in the wired controller is connected to the main board of the wired controller via an FPC cable to complete circuit conduction, facilitating disassembly and maintenance without requiring a complete replacement of the wired controller. The temperature and humidity sensor can be directly replaced by unplugging the FPC cable, reducing waste and saving costs. Fault analysis of the temperature and humidity sensor based on communication status data and humidity start-up data is more conducive to accurately determining the actual status of the sensor. In cases where the temperature and humidity sensor fails to detect temperature due to installation environment or material corrosion, the return air vent temperature data of the indoor unit's return air vent temperature sensor controlled by the wired controller is obtained. In heating mode, the return air vent temperature data is corrected, and the corrected auxiliary scheduling temperature is used as the indoor ambient temperature of the temperature and humidity sensor. The unit will use the auxiliary scheduling temperature as the temperature detected by the temperature and humidity sensor for unit control, enabling temperature scheduling even when the temperature and humidity sensor fails to detect temperature. This maximizes the use of the detected temperatures of other temperature sensors on the unit as the indoor ambient temperature for unit control, ensuring normal user operation, improving unit reliability, and reducing maintenance costs.

[0067] In an optional embodiment, combined with Figure 3 and Figure 4 As shown, step S204 above specifically includes:

[0068] Step S2041: Determine the communication status based on the communication status data between the wired controller motherboard and the temperature and humidity sensor;

[0069] Step S2042: If the communication status is abnormal, determine whether to enable humidity setting control based on the humidity start data, and obtain the sensor status based on whether the humidity setting control is enabled. The sensor status includes temperature and humidity sensor failure and temperature and humidity sensor no failure.

[0070] In this embodiment, after the wired controller is powered on, it can first determine the communication status based on the communication status data between the wired controller's main board and the temperature and humidity sensors, and then perform corresponding control based on different communication status conditions. When the communication status is abnormal, it determines whether the unit has enabled humidity setting control based on the humidity start data. The sensor status obtained is different depending on whether humidity setting control is enabled or not. The sensor status includes temperature and humidity sensor failure and temperature and humidity sensor no failure, and the scheduling method is also different for failure and no failure conditions.

[0071] In this embodiment, the fault status of the temperature and humidity sensor is determined based on the communication status data, which can directly determine whether the temperature and humidity sensor is damaged. In the case of abnormal communication status, the fault is not reported directly. Instead, the temperature and humidity sensor is judged based on the humidity start-up data obtained by the unit, which avoids the waste of resources caused by directly reporting the temperature and humidity sensor as faulty when the user has no demand for humidity.

[0072] In an optional embodiment, step S2041 specifically includes:

[0073] Based on the communication status data, determine whether there is at least one of the following states: no communication response, failure to read temperature and humidity data, or failure to verify data reading.

[0074] If it exists, it is determined that the communication status is abnormal, and the humidity setting control is determined based on the humidity start data.

[0075] If it does not exist, it is determined that there is no abnormality in the communication status, and the temperature and humidity data detected by the temperature and humidity sensor is read to control the operation of the unit.

[0076] In this embodiment, during the communication process between the temperature and humidity sensor and the wired controller motherboard, each data read corresponds to a response, read, and verification process. Therefore, each data acquisition corresponds to a communication response data, temperature and humidity read data, and verification data. If the response data is not received within a preset constraint time, it indicates a communication anomaly. If a response is received but the temperature and humidity data cannot be read, the temperature and humidity data reading fails, indicating a communication anomaly. If the data is read but the data verification fails, it also indicates a communication anomaly.

[0077] In some embodiments, in the event of a communication failure, the temperature and humidity sensor on the wired controller may be considered damaged. In this case, the temperature and humidity readings from the wired controller will no longer be used for unit control. However, a temperature and humidity sensor failure will not be reported. Instead, considering that the indoor unit controlled by the wired controller still has a return air vent temperature sensor that can be used for normal unit control, the controller will continue to determine whether the unit has enabled humidity setting control based on humidity startup data, and further determine whether the indoor unit's outlet air vent temperature sensor can be used to assist the temperature and humidity sensor in collecting indoor ambient temperature. Of course, if the communication is normal, the temperature and humidity sensor is working properly, and the readings from the wired controller will continue to be used as the indoor ambient temperature for unit control.

[0078] In this embodiment, by combining multiple dimensions such as communication response status, temperature and humidity data reading status, and data reading verification status to determine the communication status, it is possible to more accurately determine whether the temperature and humidity sensor of the wired controller is faulty, thereby improving the accuracy of the judgment.

[0079] In an optional embodiment, step S2042 specifically includes:

[0080] Based on the humidity start-up data, determine whether to enable the humidity setting control;

[0081] If the humidity setting control is enabled, it is determined that the temperature and humidity sensor is faulty, and the temperature and humidity sensor fault is reported and a fault prompt is given.

[0082] If the humidity setting control is not enabled, no temperature and humidity sensor fault will be reported.

[0083] In this embodiment, if the humidity start data indicates that the humidity setting control is off, the air conditioning unit does not activate humidity setting control; if the humidity start data indicates that the humidity start data indicates that the humidity setting control is on, the air conditioning unit activates humidity setting control. The humidity start data can be represented by an electrical level signal, for example, a high level indicates an on state, and a low level indicates a off state.

[0084] In some examples, if humidity control is enabled, it indicates that the user has a demand for indoor humidity. If the temperature and humidity sensor is not replaced promptly, this humidity requirement cannot be met, indicating a temperature and humidity sensor malfunction. The fault is reported to the air conditioning unit via the wired controller, and a fault message is displayed on the unit side. For example, the fault message might read, "Please replace the temperature and humidity sensor on the wired controller," to facilitate quick repair by maintenance personnel, ensuring the unit operates normally and minimizing user discomfort.

[0085] In other examples, if the unit does not have humidity setting control enabled, it can be assumed that the user has no current requirements for humidity, and the temperature and humidity sensor fault of the wired controller will not be reported, because the temperature detected by the return air inlet temperature sensor on the indoor unit can be used as an auxiliary indoor ambient temperature for normal unit control.

[0086] In this embodiment, by determining whether humidity setting control is enabled, it is possible to obtain whether the user has a humidity requirement. If there is a humidity requirement, a temperature and humidity sensor malfunction is promptly reported so that maintenance personnel can quickly repair and replace the temperature and humidity sensor on the wired controller, ensuring the normal operation of the unit. When there is no humidity requirement, the return air temperature data from the indoor unit's return air inlet temperature sensor is corrected and sent to the air conditioning unit as the indoor ambient temperature. This serves as a supplementary temperature control method for temperature and humidity sensors that have failed due to installation environment or material corrosion, maintaining normal unit operation without the need to replace the temperature and humidity sensors, resulting in high reliability and cost savings.

[0087] In an optional embodiment, combined with Figure 5 As shown, step S206 above specifically includes:

[0088] S2061. If the temperature and humidity sensor malfunction is not reported, then read the return air vent temperature data collected by the indoor unit's return air vent temperature sensor.

[0089] S2062. Compare the return air vent temperature data with a preset temperature threshold to determine whether the temperature difference exceeds the set temperature difference threshold.

[0090] S2063. If the temperature difference exceeds the set temperature difference threshold, it is determined that the indoor unit return air inlet temperature sensor is faulty, and the temperature and humidity sensor fault is reported and a fault prompt is given.

[0091] S2064. If the temperature difference does not exceed the set temperature difference threshold, it is determined that the indoor unit return air inlet temperature sensor is fault-free.

[0092] In this embodiment, the determination of whether the indoor unit's return air vent temperature sensor is faulty can be based on the temperature data collected by the sensor. When no temperature and humidity sensor fault is reported, the wired controller can read the return air vent temperature data detected by the indoor unit's return air vent temperature sensor and compare this data with a preset temperature threshold. The preset temperature threshold can be a reference value for the return air vent temperature, and the corresponding set temperature difference threshold can be a reference value used to determine whether the temperature collected by the sensor is normal. Both the preset temperature threshold and the set temperature difference threshold can be preset based on historical temperature data from the return air vent.

[0093] Furthermore, the temperature difference between the return air vent temperature data and the preset temperature threshold is calculated, and it is determined whether the temperature difference exceeds the set threshold. If it does not exceed the threshold, it indicates that the return air vent temperature data collected by the temperature sensor is normal; if it exceeds the threshold, it indicates that the return air vent temperature data collected by the temperature sensor is abnormal, indicating a fault in the indoor unit's return air vent temperature sensor. If the indoor unit's return air vent temperature sensor is faulty, the wired controller reports a temperature and humidity sensor fault to the air conditioning unit and displays a fault message on the air conditioning unit side, such as "Please replace the wired controller's temperature and humidity sensor," so that maintenance personnel can quickly repair and replace the wired controller's temperature and humidity sensor to ensure the unit's normal operation.

[0094] In this embodiment, when there is no humidity requirement, the return air vent temperature data of the indoor unit's return air vent temperature sensor is read to determine whether the sensor is faulty. This helps determine whether the return air vent temperature data detected by the indoor unit's return air vent temperature sensor can be used to correct the indoor ambient temperature and send it to the air conditioning unit. This serves as an auxiliary measure in case the temperature and humidity sensor fails due to installation environment or material corrosion, maintaining normal unit operation without the need to replace the temperature and humidity sensor, resulting in high reliability and cost savings. Furthermore, if the return air vent temperature data detected by the indoor unit's return air vent temperature sensor cannot be used for assistance, fault reporting and prompts are made promptly, allowing maintenance personnel to quickly repair or replace the temperature and humidity sensor on the wired controller, ensuring normal unit operation.

[0095] In an optional embodiment, combined with Figure 3 and Figure 6 As shown, step S208 above specifically includes:

[0096] S2081. If the temperature sensor at the return air vent of the indoor unit is fault-free, then obtain the number of indoor unit control consoles controlled by the wired controller and the unit's operating mode.

[0097] S2082. If the number of indoor unit control consoles controlled by the wired controller is at least one and the unit is running in non-heating mode, then the return air vent temperature data is read and used as the indoor ambient temperature for unit temperature control.

[0098] S2083. If the number of indoor unit control consoles controlled by the wired controller is one and the unit is running in heating mode, read the return air outlet temperature data, correct the return air outlet temperature data based on the temperature correction value, obtain the auxiliary scheduling temperature, and switch the auxiliary scheduling temperature to the indoor ambient temperature for unit temperature control.

[0099] S2084. If the number of indoor unit control consoles controlled by the wired controller is multiple and the unit is running in heating mode, calculate the indoor unit return air vent temperature reference value based on the return air vent temperature data of each indoor unit, correct the indoor unit return air vent temperature reference value based on the temperature correction value, obtain the auxiliary scheduling temperature, and switch the auxiliary scheduling temperature to the indoor ambient temperature for unit temperature control.

[0100] S2085. If the indoor unit control console controlled by the wired controller is one unit and the unit is running in non-heating mode, then the return air vent temperature data is read and used as the indoor ambient temperature for unit temperature control.

[0101] S2086. If the number of indoor unit control consoles controlled by the wired controller is multiple and the unit is running in non-heating mode, then the indoor unit return air vent temperature reference value is calculated based on the return air vent temperature data of each indoor unit and used as the indoor ambient temperature for unit temperature control.

[0102] In this embodiment, when the temperature sensor at the return air vent of the indoor unit is functioning properly, the number of indoor units controlled by the wired controller and the operating mode of the unit can be obtained. The temperature scheduling method in the event of a temperature and humidity sensor failure can be determined by combining the number of control units and the operating mode of the unit.

[0103] In some embodiments, when only one indoor unit is controlled and the unit is in heating mode, the wired controller can read the indoor unit's return air vent temperature data collected by the temperature sensor at the indoor unit's return air vent. Considering that heat around the return air vent of ducted air conditioners and other similar units is not easily dissipated when the air conditioning unit is in heating mode, the indoor unit's return air vent temperature will be relatively higher than the indoor ambient temperature. Therefore, a temperature correction value is added in heating mode. This temperature correction value is a fixed value obtained by comparing the indoor unit's return air vent temperature with the indoor ambient temperature through multiple experimental tests. Furthermore, when it is determined that the air conditioning unit is currently in heating mode, an auxiliary scheduling temperature is obtained based on the temperature correction value and adjusted according to the indoor unit's return air vent temperature. This adjustment includes adding a temperature correction value to the indoor unit's return air vent temperature data. For example, if the indoor unit's return air vent temperature data is A and the temperature correction value is x, then the auxiliary scheduling temperature is A+x. The wired controller then sends the auxiliary scheduling temperature as the indoor ambient temperature to the air conditioning unit for control processing.

[0104] In other embodiments, when the wired controller controls n (n≥2) indoor units and the unit is in heating mode, the wired controller can read the return air vent temperature data of each of the n indoor units to calculate a reference value for the indoor unit return air vent temperature. This reference value can be a calculated mean, a weighted average, a median, etc. In this embodiment, the calculated mean is used. The average return air vent temperature of the n indoor units is calculated. In heating mode, a temperature correction value is added to the average return air vent temperature to obtain the aforementioned auxiliary scheduling temperature. This temperature is then sent to the unit as the indoor ambient temperature for control processing.

[0105] In other embodiments, if the indoor unit controlled by the wired controller is a single control unit and the unit is operating in non-heating mode, the indoor unit return air vent temperature data will not be higher than the indoor ambient temperature and will be closer to it. Therefore, no correction is needed, and the indoor unit return air vent temperature data can be directly sent to the air conditioning unit as the indoor ambient temperature.

[0106] In other embodiments, if the number of indoor unit control consoles controlled by the wired controller is multiple and the unit is running in non-heating mode, the indoor unit return air vent temperature data will not be higher than the indoor ambient temperature, so no correction is needed. However, it is necessary to calculate the indoor unit return air vent temperature reference value based on the indoor unit return air vent temperature data of n indoor units, and send the indoor unit return air vent temperature reference value as the indoor ambient temperature to the air conditioning unit.

[0107] In this embodiment, the temperature control method is determined based on the number of control consoles and the unit's operating mode when the temperature and humidity sensors fail due to corrosion from building materials or humid environments. The return air vent temperature data is corrected or not corrected depending on the unit's operating mode, ensuring that the corrected auxiliary control temperature is closer to the indoor ambient temperature, thus facilitating more precise control of the air conditioning unit. Furthermore, the temperature detected by the indoor unit's air outlet temperature sensor is utilized to the maximum extent possible as the indoor ambient temperature for unit control, assisting in temperature adjustment when the temperature and humidity sensors fail. This avoids directly replacing the temperature and humidity sensors due to the inability to detect temperature, improving system reliability, reducing user maintenance costs, and ensuring normal use of the air conditioning product.

[0108] According to another aspect of the embodiments of this application, in conjunction with Figure 7 As shown, this application provides a wired controller. The wired controller performs temperature regulation control based on the wired controller temperature detection fault scheduling method described in the above embodiments. The wired controller includes a wired controller motherboard 1 and a temperature and humidity sensor 2. The wired controller motherboard 1 is provided with a ribbon cable plug terminal 3. The ribbon cable plug terminal 3 is connected to one end of an FPC ribbon cable 4, and the other end of the FPC ribbon cable 4 is connected to the temperature sensor.

[0109] Specifically, the aforementioned wired controller motherboard 1 serves as the wired controller control integrated circuit board, handling various functions of the wired controller. The aforementioned temperature and humidity sensor 2 is used to detect the ambient temperature and humidity for air conditioning unit control, such as detecting indoor ambient temperature. The aforementioned ribbon cable connector 3 can be a flip-top ribbon cable connector 3, used to connect the FPC ribbon cable 4. The aforementioned FPC ribbon cable 4 is used to connect the circuitry of the temperature and humidity sensor 2 to the wired controller motherboard 1.

[0110] Furthermore, the FPC cable 4 is soldered to the flip-top cable terminal on the mainboard 1 of the controller and plugged into the mainboard 1. The other end is connected to the circuit of the temperature and humidity sensor 2, completing the circuit conduction. When the temperature and humidity sensor 2 fails, maintenance personnel can remove the FPC cable 4 from the cable connector 3, thereby disconnecting the damaged temperature and humidity sensor 2 from the mainboard 1 of the controller and replacing the damaged temperature and humidity sensor 2 with a good one. This is not only convenient to operate and easy to disassemble and assemble, but also avoids replacing the entire controller, thus saving costs and resources, and is environmentally friendly and economical.

[0111] In an optional embodiment, the wired controller further includes at least one ventilation hole 5, a housing 6, and a sealing structure partition plate 7. The ventilation hole 5 is located on the housing 6 and close to the temperature and humidity sensor 2. The sealing structure partition plate 7 is located inside the ventilation hole 5, dividing the inner cavity of the housing 6 into a sealed area and a ventilation area. The wired controller main board 1 is located in the sealed area, and the temperature and humidity sensor 2 and the ventilation hole 5 are located in the ventilation area.

[0112] In this embodiment, one ventilation hole 5 or multiple ventilation holes 5 can be provided. Preferably, two ventilation holes 5 are provided in this embodiment, and they are respectively provided on different sides of the same position of the outer casing 6. The distance from the nearest side apex is the same, so that the two ventilation holes 5 can form convection to introduce ambient air and ensure that the temperature and humidity sensor 2 located in the outer casing 6 at the ventilation opening can more accurately detect the actual ambient temperature and humidity.

[0113] In this embodiment, the outer casing 6 is used to encapsulate the mainboard 1 and the internal structure of the wired controller, thereby protecting the internal circuitry and structure. The sealing partition plate 7 divides the inner cavity of the outer casing 6 into two areas: a sealed area and a ventilated area. The mainboard 1 and the ribbon cable connector 3 are located in the sealed area for sealing protection, while the temperature and humidity sensor 2 and the ventilation hole 5 are located in the ventilated area to facilitate air circulation with the outside environment and to collect temperature and humidity data. The FPC ribbon cable 4 is led from the ribbon cable connector 3 in the sealed area of ​​the wired controller to the ventilated area of ​​the wired controller.

[0114] In this embodiment, one end of the FPC cable 4 is connected to the cable connector 3 on the main board 1 of the wired controller, and the other end is connected to the circuit of the temperature and humidity sensor 2. The temperature and humidity sensor 2 is located near the ventilation hole 5 of the wired controller, which allows for more accurate detection of indoor ambient temperature and humidity. The sealed partition plate 7 protects the internal circuitry without hindering the temperature and humidity sensor 2 from detecting indoor ambient temperature and humidity. Furthermore, when the temperature and humidity sensor 2 fails due to corrosion from building materials or a humid environment, the outer casing 6 of the wired controller can be directly opened, and the FPC cable 4 connected to the cable connector 3 can be removed to disassemble the temperature and humidity sensor 2. This facilitates quick disassembly and repair by maintenance personnel without replacing the entire wired controller, thus saving resources and costs.
