[0104] 101. During the operation of the compressor, a target current parameter of a temperature control device corresponding to the compressor is obtained.
[0105] In the embodiment of the present invention, optionally, the target current parameter of the temperature control device includes one or more of the current pressure parameter of the temperature control device, the current exhaust parameter of the temperature control device, the current coil temperature parameter of the temperature control device, and the current current parameter of the temperature control device.

[0106] 102. Determine whether it is necessary to perform fault processing on the temperature control device according to the target current parameters of the temperature control device.
[0107] In the embodiment of the present invention, optionally, when it is determined that the temperature control device does not need to be processed, the current process is terminated, or step 101 is continued to be performed to monitor the fault of the temperature control device.
[0108] 103. When it is determined that fault processing needs to be performed on the temperature control device, fault information corresponding to the temperature control device is determined, and a fault processing operation is performed on the temperature control device according to the fault information corresponding to the temperature control device.
[0109] It can be seen that the method described in the embodiment of the present invention obtains the target current parameters of the temperature control device corresponding to the compressor during the operation of the compressor; and judges whether it is necessary to perform fault processing on the temperature control device based on the target current parameters of the temperature control device; when it is judged that the temperature control device needs to be fault processed, the fault information corresponding to the temperature control device is determined, and a fault processing operation is performed on the temperature control device based on the fault information corresponding to the temperature control device, which can improve the fault processing efficiency and accuracy of the temperature control device, so that the temperature control device can be restored to a normal state or working state in time, thereby ensuring the working efficiency of the temperature control device.
[0110] In the embodiment of the present invention, when the target current parameter of the temperature control device includes the current pressure parameter of the temperature control device, judging whether it is necessary to perform fault processing on the temperature control device according to the target current parameter of the temperature control device includes:
[0111] Determining whether a current pressure parameter of the temperature control device is used to indicate that a pressure switch of the temperature control device is disconnected, and when it is determined that the pressure switch of the temperature control device is disconnected, determining that a fault handling of the temperature control device is required;
[0112] Wherein, performing a fault handling operation on the temperature control device according to the fault information corresponding to the temperature control device includes:
[0113] When it is monitored that the duration of the disconnection of the pressure switch of the temperature control device is greater than or equal to a predetermined duration threshold that matches the type of the pressure switch, a shutdown control parameter of the compressor is determined, and the compressor is controlled to stop working according to the shutdown control parameter of the compressor;
[0114] Wherein, when the pressure switch type of the temperature control device is a first switch type, the duration threshold value that matches the first switch type is the first duration threshold value; when the pressure switch type of the temperature control device is a second switch type, the duration threshold value that matches the second switch type is the second duration threshold value;
[0115] Among them, the control pressure corresponding to the first switch type and the control pressure corresponding to the second switch type are different from each other; and the first duration threshold and the second duration threshold are different from each other, such as the duration threshold matching the first switch type can be 2 seconds, and the duration threshold matching the second switch type can be 3 minutes.
[0116] In the embodiment of the present invention, optionally, when it is determined that the pressure switch of the temperature control device is not disconnected, the process can be terminated.
[0117] In the embodiment of the present invention, optionally, the control pressure corresponding to the first switch type is greater than the control pressure corresponding to the second switch type. If the switch corresponding to the first switch type is disconnected, it is closed again and the closing lasts for a period greater than or equal to the first preset closing duration, such as 20 seconds, then the corresponding fault is determined to be eliminated. Further optionally, the timing starts from the first time the switch is disconnected. If the machine is shut down for a preset number of times (such as 3 times) within the first preset interval (such as one hour), the fault is determined to be eliminated after power-on. Further optionally, if the pressure of the pressure relief valve of the compressor is detected to be greater than the preset opening pressure, the switch corresponding to the compressor is controlled to be opened. If the pressure of the pressure relief valve is detected to be less than the preset closing pressure, the switch corresponding to the compressor is controlled to be closed. If the switch corresponding to the second switch type is disconnected, it is closed again and the closing lasts for a period greater than or equal to the second preset closing duration, such as 30 seconds, then the corresponding fault is determined to be eliminated. Further optionally, the timing starts from the first time the switch is disconnected. If the machine is shut down for a preset number of times (such as 3 times) within the second preset interval (such as one hour), the fault is locked and the corresponding fault parameters, such as the fault code, fault type, and fault severity, are sent to the indoor unit. Further optionally, for the switch corresponding to the second switch type, if it is detected that the ambient temperature when the corresponding compressor is turned on is less than or equal to the preset temperature, such as -10°C, or when it is detected that the compressor is turned on within a preset time period (such as 5 minutes), or during the defrosting process, or the oil return process, or the soft start process after the dew removal process, or the refrigerant removal process after the refrigeration oil return process, the low-pressure switch disconnection detection is shielded. Further optionally, when it is detected that the compressor is turned on but not running, at this time, if it is detected that its control pressure is less than or equal to the preset control pressure that meets the predetermined need to control the switch to disconnect for a duration greater than or equal to the preset duration threshold (such as 60 seconds), the compressor disconnection control parameter is generated, and the compressor switch is controlled to disconnect according to the disconnection control parameter, and an alarm message is output.
[0118] It can be seen that for pressure parameter type faults, this optional embodiment indicates that it is ready to perform fault processing when it is determined that the high-pressure switch or the low-pressure switch is disconnected, and analyzes the duration of the high-pressure switch and the low-pressure switch being disconnected respectively, so as to accurately generate corresponding control parameters and further accurately control the compressor.

[0123] When it is monitored that the current exhaust temperature of the temperature control device is greater than or equal to the third preset exhaust temperature (such as 115° C.) for a duration (such as 10 seconds) greater than or equal to the first preset duration, an exhaust protection control parameter of the temperature control device is generated, and according to the exhaust protection control parameter of the temperature control device, an exhaust protection operation is performed on the temperature control device, specifically, hot air is discharged from the compressor and its surroundings to reduce the temperature. It should be noted that during exhaust, the compressor is in a shutdown state;
[0124] In the embodiment of the present invention, the first preset exhaust temperature is lower than the second preset exhaust temperature and lower than the third preset exhaust temperature.
[0125] In the embodiment of the present invention, optionally, when it is determined that the current exhaust temperature of the temperature control device is less than the first preset exhaust temperature, it is determined that there is no need to perform fault processing on the temperature control device.
[0126] In the embodiment of the present invention, it is optional to specifically generate a frequency limiting control parameter of the compressor according to the current exhaust temperature and the second preset exhaust temperature, and perform a frequency limiting operation on the compressor.
[0127] In the embodiment of the present invention, further optionally, after the compressor is shut down and the exhaust is completed, when the duration is monitored to be greater than or equal to the preset exhaust completion time (such as 3 minutes), the current exhaust temperature of the temperature control device is collected. If it is less than or equal to the first preset exhaust temperature, the fault is restored. Further, if a preset exhaust fault occurs a number of times (such as 3 times) within a preset interval (such as one hour) after the first shutdown and exhaust is completed, the fault is locked, and the exhaust fault parameters such as the fault code, the number of faults, etc. are displayed all the time, and the temperature control device is powered off, and the fault is restored after it is powered on again.
[0128] It should be noted that the current exhaust temperature of the temperature control device can be understood as the current exhaust temperature of the outdoor unit and / or the indoor unit (including the compressor).
[0129] It can be seen that the embodiment of the present invention monitors the exhaust temperature corresponding to the temperature control device in sections for exhaust parameter type failures, and accurately takes corresponding frequency limiting or exhaust operations at different stages, which effectively protects the equipment and is beneficial to extending the service life of the equipment.
[0130] In the embodiment of the present invention, optionally, when the target current parameter of the temperature control device includes the current coil temperature parameter of the temperature control device, judging whether it is necessary to perform fault processing on the temperature control device according to the target current parameter of the temperature control device includes:

[0134] Wherein, the first preset coil temperature is less than the second preset coil temperature is less than the third preset coil temperature. In the embodiment of the present invention, optionally, when it is determined that the current indoor coil temperature of the temperature control device is less than the first preset coil temperature, it is determined that no fault processing is required for the temperature control device.
[0135] In the embodiment of the present invention, optionally, when the compressor is in a heating working state, it is necessary to collect the indoor coil temperature of the temperature control device.
[0136] In the embodiment of the present invention, optionally, when executing the over-temperature protection operation on the temperature control device, specifically, controlling the compressor to shut down. Further, the fault parameters may be displayed or not, such as the fault code, the current coil temperature and the coil temperature change, and the coil temperature at the time of shutdown may be recorded.
[0137] In the embodiment of the present invention, it is further optional that after the fault processing is performed, the heating data corresponding to the temperature control device continues to be collected to perform fault recovery. Specifically, when the duration of the monitored coil temperature being less than or equal to the fourth preset coil temperature (such as 55°C) is greater than or equal to the preset coil duration (such as 10 seconds), and / or, when the monitored coil temperature is less than or equal to the aforementioned recorded coil temperature when the compressor is shut down due to a fault minus the preset temperature (such as 2°C) or when the monitored coil temperature is less than or equal to the fifth preset coil temperature, and / or, when the external unit of the temperature control device meets the temperature shutdown and restart conditions, such as detecting that the current ambient temperature is less than or equal to the preset ambient temperature, or detecting a voice startup control command, etc., the fault is recovered.
[0138] The fifth preset coil temperature is less than the fourth preset coil temperature which is less than the first preset coil temperature.
[0139] It can be seen that the embodiment of the present invention monitors the coil temperature in real time for coil type faults, and when different node temperatures are monitored, frequency is limited first, and then the machine is shut down for over-temperature protection. That is, through this step-by-step fault handling judgment and processing link, while ensuring the effective operation of the temperature control device, the temperature control device is protected, and the occurrence of damage to the coil or other components due to excessive temperature can be reduced, which is beneficial to extending the service life of the equipment.
[0140] In the embodiment of the present invention, optionally, when the target current parameter of the temperature control device includes a current current parameter of the temperature control device, the current current parameter of the temperature control device includes an input current of a drive module of the compressor and / or a compressor phase current of a drive module of the compressor;
[0141] Wherein, judging whether it is necessary to perform fault processing on the temperature control device according to the target current parameters of the temperature control device includes:
[0142] Determining whether a current current parameter of the temperature control device is an abnormal current parameter, and when it is determined that the current current parameter of the temperature control device is an abnormal current parameter, determining that a fault processing needs to be performed on the temperature control device;
[0143] Wherein, performing a fault handling operation on the temperature control device according to the fault information corresponding to the temperature control device includes:
[0144] When it is monitored that the input current of the driving module of the compressor is greater than or equal to a first preset current (such as 26.1A), the frequency limiting control parameter of the compressor is determined, and the frequency limiting operation is performed on the compressor according to the frequency limiting control parameter of the compressor, wherein the operating frequency of the compressor after the frequency limiting is lower than the operating frequency before the frequency limiting; when it is monitored that the input current of the driving module of the compressor is greater than or equal to a second preset current (such as 30.1A), the protection control parameter of the compressor is generated, and the protection operation is performed on the compressor according to the protection control parameter of the compressor;
[0145] When it is monitored that the compressor phase current of the driving module of the compressor is greater than or equal to the third preset current (such as 20.1A), the frequency limiting control parameter of the compressor is determined, and the frequency limiting operation is performed on the compressor according to the frequency limiting control parameter of the compressor, wherein the operating frequency of the compressor after the frequency limiting is lower than the operating frequency before the frequency limiting; when it is monitored that the compressor phase current of the driving module of the compressor is greater than or equal to the fourth preset current (such as 25.1A), the protection control parameter of the compressor is generated, and the protection operation is performed on the compressor according to the protection control parameter of the compressor;
[0146] The third preset current is smaller than the fourth preset current which is smaller than the first preset current which is smaller than the second preset current.
[0147] In the embodiment of the present invention, optionally, when it is determined that the current parameter of the temperature control device is a normal current parameter, it is determined that there is no need to perform fault processing on the temperature control device. The abnormal current parameter includes but is not limited to abnormal conditions such as current fluctuations within a preset time period or sudden current spikes.
[0148] In the embodiment of the present invention, optionally, the input current and the phase current correspond to different drive modules and matching respectively, and the frequency limit and protection values are determined according to the corresponding matching numbers and drive modules.
[0149] In the embodiment of the present invention, optionally, after each current fault processing before a preset current number of times (such as 2 times) is completed, the temperature control device restarts after a preset shutdown time (such as 3 minutes). Furthermore, if a preset current fault number (such as 3 times) occurs within a preset interval time (such as one hour) after the first shutdown, a permanent shutdown alarm is issued, and the alarm can be canceled after the entire system is powered on again.
[0150] It can be seen that in the embodiment of the present invention, for current parameter type faults, the main control, that is, the temperature control device, performs frequency limiting and protection control according to the input current fed back by the compressor drive module and the compressor phase current, respectively, thereby achieving precise control of current protection under different circumstances.
[0151] In the embodiment of the present invention, optionally, in addition to the aforementioned faults, there may be, but not limited to, communication faults and / or module faults. Among them, for communication faults, communication is the communication between the external unit and the drive module of the temperature control device. When there is no communication transmission between the external unit and the drive module for a preset interval communication time (such as 30s), if no normal working data is received, it indicates that there is a communication fault between the two. At this time, check the cause of the fault, and generate and display the corresponding fault parameters (such as fault code) according to the cause of the fault. Shut down, and perform fault handling operations according to the fault parameters, such as resending normal communication data, and restoring communication after receiving normal communication data. For module faults, specifically IPM (Intelligent Power Module) module, that is, intelligent power module, is a power semiconductor device that organically combines power electronics and integrated circuit technology. When a fault occurs, it will immediately shut down and display fault parameters, such as normal codes, and the drive module protection will be restored, and the main control protection will also be restored, and the fault will not be locked. More specifically, the temperature detected by the IPM module itself is used as the control reference value. The IPM module transmits the detected temperature to the main control board of the temperature control device. Starting from the first time, if the temperature abnormality is detected each time for the previous preset number of times (such as 5 times), such as when the temperature is greater than the preset module temperature, the main control board will shut down, and after a preset time (such as 45 seconds) after the shutdown is detected, the temperature control device will be restarted. At this time, the driver module protection is restored, and the main control board protection is also restored. Optionally, if the preset abnormal number of shutdowns (such as 6 times) occurs continuously within a preset interval time period (such as one hour), the temperature control device is controlled to permanently shut down and alarm, and the alarm is canceled after the entire temperature control device is powered on again.
[0152] In an optional embodiment, the method may further include the following steps:
[0153] According to the fault information corresponding to the temperature control device, determining whether the current condition corresponding to the temperature control device meets the predetermined fault parameter sending condition;
[0154] When it is determined that the fault parameter sending condition is met, a fault parameter matching the fault information is generated according to the fault information corresponding to the temperature control device;
[0155] According to the fault information corresponding to the temperature control device, determine the fault parameter receiving component matching the fault information;
[0156] The fault parameter receiving component matching the fault information sends the fault parameter matching the fault information.
[0157] In this optional embodiment, different fault types may correspond to different fault information and fault parameters. For example, the fault code corresponding to the exhaust temperature fault is A4, and the fault code corresponding to the coil temperature fault is A8. For other details, please refer to the detailed description of the corresponding contents above and will not be repeated here.
[0158] In the embodiment of the present invention, optionally, when it is determined that the fault parameter sending condition is not met, the current process is terminated. Different fault types have corresponding fault parameter sending conditions. If a corresponding fault code is generated, the fault parameter sending condition is met, or the current fault type is a situation where the temperature control device is shut down but there is an urgent need to put it into working state, which satisfies the fault parameter sending condition, etc. Further, different fault types have corresponding fault parameter receiving components. For example, for a pressure switch fault, the fault parameter receiving component is the indoor unit of the temperature control device.
[0159] It can be seen that after a fault occurs, if this optional embodiment further determines that the fault sending conditions are met, it will further generate corresponding fault parameters and send them to the corresponding fault parameter receiving component, so that the corresponding component can know the fault situation and make accurate corresponding actions, such as prompting the staff to repair the fault or stopping the function associated with the fault according to the received fault, so as to improve the convenience and efficiency of fault diagnosis and improve the accuracy of fault location.
[0160] In another optional embodiment, after performing a fault handling operation on the temperature control device according to the fault information corresponding to the temperature control device, the method may further include the following steps:
[0161] Monitor real-time data of temperature control equipment;
[0162] According to the real-time data of the monitored temperature control device, determining whether the current condition of the temperature control device meets the predetermined fault recovery condition matching the fault information of the temperature control device;
[0163] When it is determined that the fault recovery condition is met, a fault recovery control parameter matching the fault information of the temperature control device is generated according to the real-time data of the monitored temperature control device and the fault information of the temperature control device;
[0164] According to the fault recovery control parameters corresponding to the temperature control device, a fault recovery operation matching the fault information of the temperature control device is performed on the temperature control device.
[0165] In this optional embodiment, different fault types correspond to different real-time data. For example, a pressure switch type fault corresponds to real-time pressure data, including the pressure size and the corresponding duration. A coil fault type corresponds to the coil temperature, as well as other technical contents of fault recovery. For details, please refer to the description of the corresponding fault type above and will not be repeated here.
[0166] In this optional embodiment, optionally, when it is determined that the non-fault recovery condition is met, the process ends.
[0167] It can be seen that after processing the fault, this optional embodiment generates corresponding fault recovery control parameters for different fault types after monitoring that the corresponding fault recovery conditions are met, and performs fault recovery to restore the temperature control device to a normal state or a normal working state, so as to meet the user's temperature requirements and improve the user experience.
[0168] In yet another optional embodiment, the method may further include the following steps:
[0169] Obtain the number of failures of the temperature control device within a preset time period (such as 3 months) and the failure data of each failure, and analyze the failure data of each failure to determine whether there is at least one group of associated failures that cause the failure association;
[0170] When it is determined that there is at least one group of associated fault groups that cause fault association, for any group of associated fault groups, based on the fault data of all faults contained in the associated fault group, analyze the number of occurrences of faults caused by the association within a preset time period, and determine whether the number of occurrences is greater than or equal to a predetermined threshold number of occurrences corresponding to the associated fault group within the preset time period; when the result of the determination is yes, based on the fault types of all faults in the associated fault group, a first association identifier is set for all faults in the associated fault group, wherein the first association identifier corresponding to each associated fault group is used for when any one type of fault in the associated fault group occurs, to perform a check operation on parameters corresponding to other fault types of the associated fault group according to the first association identifier; optionally, when the result of the determination is yes, If no, determine whether there is a fault type in the associated fault group whose importance is greater than or equal to a preset importance (such as 90%). When it is determined that there is a fault type, a second associated identifier is set for all faults in the associated fault group according to the fault types of all faults in the associated fault group, wherein the second associated identifier corresponding to each associated fault group is used for when a fault type other than the fault type with an importance greater than or equal to the preset importance occurs in the associated fault group, perform an inspection operation on the parameters corresponding to the fault type with an importance greater than or equal to the preset importance of the associated fault group according to the second associated identifier. At this time, the parameter can be one of the aforementioned pressure parameters, exhaust parameters, coil temperature parameters and current parameters. Furthermore, it can also include operating parameters of corresponding components, such as working gear, working time, etc.
[0171] In this optional embodiment, optionally, the fault data of each fault includes the type of fault, the time of the fault, and the equipment data when the fault occurs, wherein the time of the fault includes the time when the fault starts, the time when the fault ends, and the duration of the fault, and the equipment data when the fault occurs includes the equipment operation data and the environmental data generated by the equipment operation, wherein the equipment operation data includes the parameter types referred to above, such as one or more of the pressure parameter type, the exhaust parameter type, the coil temperature parameter type, and the current parameter type. The environmental data generated by the equipment operation includes the ambient temperature and / or the ambient airflow. It should be noted that the flow of the airflow and the temperature change may affect the working changes between the components of the temperature control device.
[0172] In this optional embodiment, optionally, the fault types of all faults are the fault types referred to above, such as a pressure fault type, an exhaust fault type, a coil temperature fault type, and a current fault type.
[0173] In this optional embodiment, when a fault occurs, it may cause or lead to the occurrence of another fault, indicating that there is an associated fault relationship between the two. For example, when an exhaust fault occurs, the coil temperature rises rapidly due to the exhaust, indicating that there is an associated fault relationship between the two. At this time, if the exhaust fault causes or aggravates the coil fault, or the coil fault causes or aggravates the exhaust fault, and occurs 6 times within 3 months, which is more than the fixed 5 times, then an associated identifier between the two is established, so that when a coil fault occurs, an inspection operation is performed on the exhaust, or, when an exhaust fault occurs, an inspection is performed on the coil temperature. For another example, when a pressure fault occurs, the coil temperature rises rapidly due to the pressure, indicating that there is an associated fault relationship between the two. At this time, if the pressure fault causes or aggravates the coil fault, or the coil fault causes or aggravates the pressure fault, and occurs 2 times within 3 months, which is less than the fixed 3 times, and the importance of the pressure fault is greater than the importance of the coil, then an associated identifier between the two is still established, so that when a coil fault occurs, an inspection operation is performed on the parameters that may cause the pressure fault.
[0174] It can be seen that this optional embodiment can also analyze the data of all faults occurring within a period of time, and set corresponding association identifiers for associated fault groups that are associated with faults that frequently occur within a period of time, or set corresponding association identifiers for associated fault groups when more important faults exist, so that when a fault type occurs in the same associated fault group subsequently, the parameters corresponding to other fault types can be automatically checked according to the corresponding association identifiers to reduce the occurrence of other types of faults, thereby helping to ensure that the equipment can be restored to an operating state in a timely manner and to increase the service life of the equipment.

[0207] When it is monitored that the input current of the driving module of the compressor is greater than or equal to a first preset current (such as 26.1A), the frequency limiting control parameter of the compressor is determined, and the frequency limiting operation is performed on the compressor according to the frequency limiting control parameter of the compressor, wherein the operating frequency of the compressor after the frequency limiting is lower than the operating frequency before the frequency limiting; when it is monitored that the input current of the driving module of the compressor is greater than or equal to a second preset current (such as 30.1A), the protection control parameter of the compressor is generated, and the protection operation is performed on the compressor according to the protection control parameter of the compressor;

[0216] It can be seen that the implementation Figure 3 After a fault occurs, the described device further generates corresponding fault parameters and sends them to the corresponding fault parameter receiving component if it is determined that the fault sending conditions are met, so that the corresponding component is aware of the fault situation and can take accurate corresponding actions, such as prompting the staff to repair the fault or stopping the function associated with the fault according to the received fault, so as to improve the convenience and efficiency of fault diagnosis and improve the accuracy of fault location.

[0220] The second generating module 208 is used to generate a fault recovery control parameter matching the fault information of the temperature control device according to the monitored real-time data of the temperature control device and the fault information of the temperature control device when it is determined that the fault recovery condition is met;
[0221] The fault processing module 204 is further configured to perform a fault recovery operation on the temperature control device that matches the fault information of the temperature control device according to the fault recovery control parameters corresponding to the temperature control device.
[0222] It can be seen that the implementation Figure 3 After processing the fault, the described device generates corresponding fault recovery control parameters for different fault types after monitoring that the corresponding fault recovery conditions are met, and performs fault recovery to restore the temperature control device to a normal state or a normal working state, thereby meeting the user's temperature requirements and improving the user experience.
