[0102] Embodiment one

[0103] Please refer to Figure 1 , Figure 1 It is a kind of temperature control equipment fault handling method flow diagram disclosed in the embodiment of the application. Among them, Figure 1 The method described can be applied to food material automatic cooking device, wherein the food material automatic cooking device can include temperature control equipment, control server for controlling temperature control equipment, control platform for controlling temperature control equipment, one of control system for controlling temperature control equipment, wherein control server includes local control server or remote control server or cloud control server. Wherein, as Figure 1 The temperature control equipment fault handling method can include the following operations:

[0104] 101, in the process of compressor operation, the target current parameter of temperature control equipment corresponding to compressor is acquired.

[0105] In the embodiment of the application, optionally, the target current parameter of temperature control equipment includes one or more of the current pressure parameter of temperature control equipment, the current exhaust parameter of temperature control equipment, the current coil temperature parameter of temperature control equipment and the current current parameter of temperature control equipment. Wherein, optionally, temperature control equipment can be any device containing compressor, such as frequency conversion heating machine.

[0106] 102, according to the target current parameter of temperature control equipment, it is judged whether temperature control equipment needs to be handled for fault.

[0107] In the embodiment of the application, optionally, when it is judged that temperature control equipment does not need to be handled, end this flow, or continue to execute step 101 for fault monitoring of temperature control equipment.

[0108] 103. When it is determined that the temperature control device needs to be handled for failure, the corresponding failure information of the temperature control device is determined, and the temperature control device is handled for failure according to the corresponding failure information of the temperature control device.

[0109] It can be seen that the method described in the embodiment of the application can obtain the target current parameter of the temperature control device corresponding to the compressor during the operation of the compressor, and determine whether the temperature control device needs to be handled for failure according to the target current parameter of the temperature control device. When it is determined that the temperature control device needs to be handled for failure, the corresponding failure information of the temperature control device is determined, and the temperature control device is handled for failure according to the corresponding failure information of the temperature control device. Therefore, the failure handling efficiency and accuracy of the temperature control device can be improved, so that the temperature control device can be restored to the normal state or working state in time, and the working efficiency of the temperature control device is ensured.

[0110] In the embodiment of the application, when the target current parameter of the temperature control device includes the current pressure parameter of the temperature control device, whether the temperature control device needs to be handled for failure is determined according to the target current parameter of the temperature control device, including:

[0111] whether the current pressure parameter of the temperature control device is used to indicate that the pressure switch of the temperature control device is turned off. When it is determined that the pressure switch of the temperature control device is turned off, it is determined that the temperature control device needs to be handled for failure;

[0112] In the embodiment of the application, when the target current parameter of the temperature control device includes the current pressure parameter of the temperature control device, whether the temperature control device needs to be handled for failure is determined according to the target current parameter of the temperature control device, including:

[0113] When the duration for which the pressure switch of the temperature control device is turned off is greater than or equal to the duration threshold value that matches the type of the pressure switch and is determined in advance, the 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] When the type of the pressure switch of the temperature control device is the first switch type, the duration threshold value that matches the first switch type is the first duration threshold value. When the type of the pressure switch of the temperature control device is the second switch type, the duration threshold value that matches the second switch type is the second duration threshold value.

[0115] The control pressure corresponding to the first switch type and the control pressure corresponding to the second switch type are different from each other. The first duration threshold value and the second duration threshold value are different from each other. For example, the duration threshold value that matches the first switch type can be 2 seconds, and the duration threshold value that matches the second switch type can be 3 minutes.

[0116] Optionally, when it is judged that the pressure switch of the temperature control device is not disconnected, the process can be ended.

[0117] Optionally, the control pressure corresponding to the first switch type is greater than the control pressure corresponding to the second switch type, for example. If the switch corresponding to the first switch type is disconnected, then closed and closed for greater than or equal to the first preset closing duration, such as 20 seconds, it is determined that the corresponding fault is eliminated. Further optionally, the timing starts from the first switch disconnection, and if the machine is stopped for a preset number of times, such as 3 times, within a first preset interval, such as one hour, it is determined that the fault is eliminated after power-on. Further optionally, if the pressure of the pressure relief valve of the compressor is greater than the preset opening pressure, the switch corresponding to the compressor is opened. If the pressure of the pressure relief valve is less than the preset closing pressure, the switch corresponding to the compressor is closed. If the switch corresponding to the second switch type is disconnected, then closed and closed for greater than or equal to the second preset closing duration, such as 30 seconds, it is determined that the corresponding fault is eliminated. Further optionally, the timing starts from the first switch disconnection, and if the machine is stopped for a preset number of times, such as 3 times, within a second preset interval, such as one hour, the fault is locked and the corresponding fault parameters, such as 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 the ambient temperature during the start-up of the compressor is less than or equal to the preset temperature, such as -10°C, or if the compressor is detected to be started within a preset time period, such as 5 minutes, or during defrosting, or during oil return, or during soft start after dew removal, or during refrigerant discharge after oil return, the low-pressure switch disconnection detection is shielded. Further optionally, when the compressor is detected to be started but not running, if the control pressure is detected to be less than or equal to the preset control pressure that meets the predetermined requirement for switch disconnection for a duration greater than or equal to a preset duration threshold, such as 60 seconds, a disconnection control parameter of the compressor is generated, the switch of the compressor is controlled to be disconnected according to the disconnection control parameter, and an alarm information is output.

[0118] It can be seen that, for the pressure parameter type fault, the optional embodiment indicates that fault handling is to be performed when the high-pressure switch or the low-pressure switch is disconnected, and the duration of the disconnection of the high-pressure switch and the low-pressure switch is analyzed respectively, so as to accurately generate the corresponding control parameter and accurately control the compressor.

[0119] Optionally, when the target current parameter of the temperature control device includes the current exhaust parameter of the temperature control device, whether the temperature control device needs to be handled according to the target current parameter of the temperature control device, including:

[0120] determining whether the current pressure parameter of the temperature control device is used to represent that the current exhaust temperature of the temperature control device is greater than or equal to a first preset exhaust temperature (such as 90 DEG C), and when it is determined that the current exhaust temperature of the temperature control device is greater than or equal to the first preset exhaust temperature, it is determined that the temperature control device needs to be handled for failure;

[0121] According to the fault information corresponding to the temperature control device, the fault handling operation is performed on the temperature control device, including:

[0122] When it is monitored that the current exhaust temperature of the temperature control device is greater than or equal to a second preset exhaust temperature (such as 105 DEG C), a frequency limiting control parameter of the compressor is generated, and the compressor is controlled to perform a frequency limiting operation according to the frequency limiting control parameter of the compressor, wherein the working frequency of the compressor after frequency limiting is lower than the working frequency before frequency limiting;

[0123] When it is monitored that the current exhaust temperature of the temperature control device is greater than or equal to a third preset exhaust temperature (such as 115 DEG C) for a duration (such as 10 seconds) greater than or equal to a first preset duration, an exhaust protection control parameter of the temperature control device is generated, and the exhaust protection operation is performed on the temperature control device according to the exhaust protection control parameter of the temperature control device, specifically, the hot gas is discharged from the compressor and its surroundings to reduce the temperature, and it needs to be explained that the compressor is in a shutdown state during the exhaust;

[0124] In the embodiment of the application, the first preset exhaust temperature is less than the second preset exhaust temperature, and the second preset exhaust temperature is less than the third preset exhaust temperature.

[0125] In the embodiment of the application, 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 the temperature control device does not need to be handled for failure.

[0126] In the embodiment of the application, optionally, the frequency limiting control parameter of the compressor is generated according to the current exhaust temperature and the second preset exhaust temperature, and the frequency limiting operation is performed on the compressor.

[0127] In the embodiment of the application, further optionally, after the compressor shutdown exhaust is completed, when it is monitored that the duration is greater than or equal to a preset exhaust completion duration (such as 3 minutes), the current exhaust temperature of the temperature control device is collected, and if it is less than or equal to the first preset exhaust temperature, the failure is recovered.

[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, for the exhaust parameter type fault, the embodiment of the present application performs segmented monitoring on the exhaust temperature corresponding to the temperature control device, and accurately takes corresponding frequency limiting or exhaust operation at different stages, which effectively protects the device and is beneficial to prolong the service life of the device.

[0130] In the embodiment of the present application, when the target current parameter of the temperature control device includes the current coil temperature parameter of the temperature control device, whether the temperature control device needs to be handled according to the target current parameter of the temperature control device, including:

[0131] determining whether the current coil temperature parameter of the temperature control device is used to indicate whether the current indoor coil temperature of the temperature control device is greater than or equal to the first preset coil temperature, when it is determined that the current indoor coil temperature of the temperature control device is greater than or equal to the first preset coil temperature (such as 50℃), it is determined that the temperature control device needs to be handled;

[0132] wherein, according to the fault information corresponding to the temperature control device, the temperature control device is executed for fault handling operation, including:

[0133] when the current indoor coil temperature of the temperature control device is greater than or equal to the second preset coil temperature (such as 59℃), the frequency limiting control parameter of the compressor is generated, and the compressor is controlled to execute the frequency limiting operation according to the frequency limiting control parameter of the compressor, wherein the working frequency of the compressor after frequency limiting is lower than the working frequency before frequency limiting; when the current exhaust temperature of the temperature control device is greater than or equal to the third preset coil temperature (such as 61℃) for a duration greater than or equal to the second preset duration, the over-temperature protection control parameter of the temperature control device is generated, and the over-temperature protection operation of the temperature control device is executed according to the over-temperature protection control parameter of the temperature control device, specifically, the compressor is controlled to stop, and further, the coil is cooled;

[0134] wherein, the first preset coil temperature is less than the second preset coil temperature, and the second preset coil temperature is less than the third preset coil temperature. In the embodiment of the present application, 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 the temperature control device does not need to be handled.

[0135] In the embodiment of the present application, when the compressor is in a heating working state, the indoor coil temperature of the temperature control device needs to be collected.

[0136] Optionally, in the embodiment of the present application, the over-temperature protection operation is performed on the temperature control device, and specifically, the compressor is stopped. Further, the fault parameters can 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 is recorded.

[0137] In the embodiment of the present application, further optionally, after the fault processing, the heating data corresponding to the temperature control device is continuously collected for fault recovery. Specifically, when it is monitored that the coil temperature is less than or equal to the fourth preset coil temperature (such as 55℃) for a duration greater than or equal to the preset coil duration (such as 10 seconds), and / or when it is monitored that the coil temperature is less than or equal to the recorded coil temperature at the time of compressor fault shutdown minus the preset temperature (such as 2℃) or when it is monitored that the coil temperature is less than or equal to the fifth preset coil temperature, and / or the outdoor unit of the temperature control device meets the temperature shutdown and restart conditions, such as detecting that the current environment temperature is less than or equal to the preset environment temperature, or detecting the voice start control instruction, 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, for the coil type fault, the coil temperature is monitored in real time, and when the temperature at different nodes is monitored, the frequency is limited first, and then the over-temperature protection is stopped, that is, through this gradual fault processing judgment and processing link, the temperature control device is protected while ensuring the effective work of the temperature control device, and the damage of the coil or other components due to high temperature is reduced, which is beneficial to prolong the service life of the equipment.

[0140] Optionally, in the embodiment of the present application, when the target current parameter of the temperature control device includes the current current parameter of the temperature control device, the current current parameter of the temperature control device includes the input current of the driving module of the compressor and / or the phase current of the driving module of the compressor.

[0141] The target current parameter of the temperature control device is determined according to the target current parameter of the temperature control device, including:

[0142] The current current parameter of the temperature control device is determined to be an abnormal current parameter, and when it is determined that the current current parameter of the temperature control device is an abnormal current parameter, it is determined that the fault processing of the temperature control device is needed.

[0143] The fault processing operation of the temperature control device is performed according to the fault information corresponding to the temperature control device, including:

[0144] When the input current of the driving module of the compressor is monitored to be greater than or equal to a first preset current (such as 26.1 A), a frequency limiting control parameter of the compressor is determined, and a frequency limiting operation is performed on the compressor according to the frequency limiting control parameter of the compressor, wherein the working frequency of the compressor after frequency limiting is lower than the working frequency before frequency limiting; when the input current of the driving module of the compressor is monitored to be greater than or equal to a second preset current (such as 30.1 A), a protection control parameter of the compressor is generated, and a protection operation is performed on the compressor according to the protection control parameter of the compressor;

[0145] When the compressor phase current of the driving module of the compressor is monitored to be greater than or equal to a third preset current (such as 20.1 A), a frequency limiting control parameter of the compressor is determined, and a frequency limiting operation is performed on the compressor according to the frequency limiting control parameter of the compressor, wherein the working frequency of the compressor after frequency limiting is lower than the working frequency before frequency limiting; when the compressor phase current of the driving module of the compressor is monitored to be greater than or equal to a fourth preset current (such as 25.1 A), a protection control parameter of the compressor is generated, and a protection operation is performed on the compressor according to the protection control parameter of the compressor;

[0146] The third preset current is less than the fourth preset current, the first preset current is less than the second preset current.

[0147] In the embodiment of the present application, optionally, when it is judged that the current parameter of the temperature control device is a normal current parameter, it is determined that the temperature control device does not need to be handled for failure. The abnormal current parameter includes, but is not limited to, fluctuation of current within a preset time period or sudden peak of current, etc.

[0148] In the embodiment of the present application, optionally, the input current and the phase current correspond to different driving modules and matching, and the values of frequency limiting and protection are determined according to the corresponding number of matches and driving modules.

[0149] In the embodiment of the present application, optionally, after each current failure handling before a preset current number of times (such as 2 times) is completed, the temperature control device is restarted after a preset downtime (such as 3 minutes). Further, if a preset current failure number of times (such as 3 times) occurs within a preset interval time (such as one hour) after the first downtime, permanent downtime alarm is generated, and the alarm can be cancelled after the entire system is powered on.

[0150] It can be seen that, for the current parameter type failure, the master control, i.e. the temperature control device, respectively performs frequency limiting and protection control according to the input current and the compressor phase current fed back by the driving module of the compressor, so that precise current protection control under different conditions is realized.

[0151] In the embodiment of the present application, in addition to the aforementioned failures, there can be communication failures and / or module failures, but not limited to. For the communication failure, the communication is the communication between the outdoor unit of the temperature control device and the drive module. When the outdoor unit and the drive module do not communicate for a preset interval communication duration (such as 30s), such as no normal working data is received, it indicates that there is a communication failure between the two. At this time, the failure cause is checked, and according to the failure cause, the corresponding failure parameter (such as failure code) is generated and displayed to stop, and according to the failure parameter, the failure handling operation is performed, such as re-sending normal communication data. After receiving the normal communication data, the communication is restored. For the module failure, it is specifically the IPM (Intelligent Power Module) module, that is, an intelligent power module, which is a power semiconductor device that organically combines power electronics and integrated circuit technology. When a failure occurs, it immediately stops and displays a failure parameter, such as a failure code. The drive module protection is restored, and the main control protection is also restored, and the fault is not locked. More specifically, the temperature detected by the IPM module is taken as the control reference value. The IPM module transmits the detected temperature to the main control board of the temperature control device. From the first time, if the temperature is abnormal, such as the temperature is greater than the preset module temperature, the temperature control device stops, and after standby for a preset time (such as 45 seconds) after the stop is detected, the temperature control device is restarted. At this time, the drive module protection is restored, and then the main control board protection is also restored. Optionally, if the preset abnormal number (such as 6 times) of stop occurs continuously within a preset interval duration (such as one hour), the temperature control device is permanently stopped and an alarm is generated, and the alarm is canceled after the entire temperature control device is powered on again.

[0152] In an optional embodiment, the method can further include the following steps:

[0153] According to the corresponding failure information of the temperature control device, it is judged whether the current condition of the temperature control device meets the pre-determined failure parameter sending condition;

[0154] When it is judged that the failure parameter sending condition is met, according to the corresponding failure information of the temperature control device, the failure parameter matched with the failure information is generated;

[0155] According to the corresponding failure information of the temperature control device, the failure parameter collection component matched with the failure information is determined;

[0156] The failure parameter matched with the failure information is sent to the failure parameter collection component matched with the failure information.

[0157] In the optional embodiment, optionally, different fault types correspond to different fault information and fault parameters, for example, the fault code corresponding to the exhaust temperature fault is A4, the fault code corresponding to the coil temperature fault is A8, and other contents are described in detail in the foregoing corresponding contents, which will not be repeated here.

[0158] In the embodiment of the application, optionally, when it is judged that the fault parameter sending condition is not met, the current process is ended. Different fault types have corresponding fault parameter sending conditions, for example, if a corresponding fault code is generated, the fault parameter sending condition is met, or the current fault type is a situation in which the temperature control device is stopped but needs to be brought into a working state urgently, the fault parameter sending condition is met, and the like. Further, different fault types have corresponding fault parameter collecting components, for example, for a pressure switch fault, the fault parameter collecting component of the temperature control device is an indoor unit of the temperature control device.

[0159] It can be seen that, in the optional embodiment, after a fault occurs, if it is further judged that the fault sending condition is met, the corresponding fault parameter is further generated and sent to the corresponding fault parameter collecting component, so that the corresponding component knows the fault condition and makes accurate corresponding action, for example, prompts a worker to repair the fault or stops a function associated with the fault according to the received fault, to improve the fault diagnosis convenience and efficiency and improve the positioning accuracy of the fault.

[0160] In another optional embodiment, after the temperature control device is executed with the fault handling operation according to the fault information of the temperature control device, the method can further include the following steps:

[0161] Monitoring real-time data of the temperature control device;

[0162] According to the monitored real-time data of the temperature control device, it is judged whether the current condition of the temperature control device meets a fault recovery condition that is determined in advance and matches the fault information of the temperature control device;

[0163] When it is judged that the fault recovery condition is met, a fault recovery control parameter that matches the fault information of the temperature control device is generated according to the monitored real-time data of the temperature control device and the fault information of the temperature control device;

[0164] According to the fault recovery control parameter corresponding to the temperature control device, the temperature control device is executed with a fault recovery operation that matches the fault information of the temperature control device.

[0165] In the optional embodiment, different fault types correspond to different real-time data. For example, the pressure switch type fault corresponds to the pressure real-time data, including the pressure size and the corresponding duration. For another example, the coil fault type corresponds to the coil temperature. Other technical contents of fault recovery are described above in the description of the corresponding fault types, and will not be described here again.

[0166] In the optional embodiment, when it is judged that the non-fault recovery condition is met, the current process is ended.

[0167] It can be seen that, after the fault is processed, for different fault types, when it is monitored that the corresponding fault recovery condition is met, the corresponding fault recovery control parameter is generated, and the fault recovery is performed, so that the temperature control device returns to the normal state or the normal working state, so as to meet the user's demand for temperature and improve the user experience.

[0168] In yet another optional embodiment, the method can further include the following steps:

[0169] The number of faults of the temperature control device occurring in a preset time period (for example, 3 months) and the fault data of each fault occurring are obtained, and the fault data of each fault occurring is analyzed to determine whether there is at least one group of associated faults that causes the fault association;

[0170] When it is judged that there is at least one set of associated fault groups causing the fault association, for any one set of associated fault groups, according to the fault data of all faults contained in the set of associated fault groups, the number of occurrences of the fault caused by the association in a preset time period is analyzed, and it is judged whether the number of occurrences is greater than or equal to a predetermined occurrence threshold value of the set of associated fault groups in the preset time period; when the result is yes, according to the fault types of all faults of the set of associated fault groups, a first association identifier is set for all faults of the set of associated fault groups, wherein the first association identifier corresponding to each set of associated fault groups is used to perform a check operation on the parameters corresponding to other fault types of the set of associated fault groups according to the first association identifier when any one fault type in the set of associated fault groups occurs; optionally, when the result is no, it is determined whether there is a fault type in the set of associated fault groups whose importance is greater than or equal to a preset importance (such as 90%); when it is judged that there is, according to the fault types of all faults of the set of associated fault groups, a second association identifier is set for all faults of the set of associated fault groups, wherein the second association identifier corresponding to each set of associated fault groups is used to perform a check operation on the parameters corresponding to the fault type whose importance is greater than or equal to the preset importance of the set of associated fault groups according to the second association identifier when the fault type other than the fault type whose importance is greater than or equal to the preset importance in the set of associated fault groups occurs. At this time, the parameter can be one of the aforementioned pressure parameter, exhaust parameter, coil temperature parameter and current parameter, and further can include operating parameters of the corresponding components, such as working gear, working time, etc.

[0171] In the optional embodiment, the fault data of each occurrence of fault includes fault occurrence type, fault occurrence time, and device data at the time of fault occurrence, wherein the fault occurrence time includes fault start occurrence time, fault end occurrence time and fault occurrence time length, and the device data at the time of fault occurrence includes device operating data and environment data generated by device operation, wherein the device operating data includes one or more of the aforementioned parameter types, such as pressure parameter type, exhaust parameter type, coil temperature parameter type and current parameter type. The environment data generated by device operation includes environmental temperature and / or environmental airflow. It should be noted that the flow and temperature change of the airflow can affect the working change between the components of the temperature control device.

[0172] In the optional embodiment, the fault type of all faults is the aforementioned fault type, such as pressure fault type, exhaust fault type, coil temperature fault type and current fault type, etc.

[0173] In the optional embodiment, when one fault occurs, and the occurrence of another fault is caused or resulted, it indicates that there is a correlated fault relationship between them. For example, when the exhaust fault occurs, the coil temperature rises rapidly due to the exhaust, which indicates that there is a correlated fault relationship between them. At this time, and within 3 months, the coil fault is caused or aggravated due to the exhaust fault, or the exhaust fault is caused or aggravated due to the coil fault, which occurs 6 times, more than the fixed 5 times, and the correlation between them is established. When the coil fault occurs, the exhaust is checked, or when the exhaust fault occurs, the coil temperature is checked. For another example, when the pressure fault occurs, the coil temperature rises rapidly due to the pressure, which indicates that there is a correlated fault relationship between them. At this time, and within 3 months, the coil fault is caused or aggravated due to the pressure fault, or the pressure fault is caused or aggravated due to the coil fault, which occurs 2 times, less than the fixed 3 times, and the importance of the pressure fault is greater than that of the coil. At this time, the correlation between them is still established, so that when the coil fault occurs, the parameters that may cause the pressure fault are checked.

[0174] It can be seen that the optional embodiment can also analyze the data of all faults occurring within a period of time, and set the corresponding correlation identifier for the correlated fault group that often causes faults within a period of time, or set the corresponding correlation identifier for the correlated fault group when there is a relatively important fault, so that when the same correlated fault group has a fault type fault, the corresponding parameters of other fault types can be automatically checked according to the corresponding correlation identifier, to reduce the occurrence of other types of faults, thereby facilitating the equipment to be restored to the running state in time, and improving the service life of the equipment.

[0176] Please refer to Figure 2 , Figure 2 is a structural schematic diagram of a fault processing device of a temperature control equipment disclosed by the embodiment of the application. Wherein, Figure 2 The device described can include one of a temperature control equipment, a control server for controlling the temperature control equipment, a control platform for controlling the temperature control equipment, and a control system for controlling the temperature control equipment, wherein the control server includes a local control server or a remote control server or a cloud control server. Wherein, as Figure 2 indicated, the fault processing device of the temperature control equipment can include:

[0177] The acquisition module 201 is configured to acquire a target current parameter of the temperature control equipment corresponding to the compressor during the operation of the compressor.

[0178] In this embodiment of the invention, the target current parameters of the temperature control device include one or more of the following: 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.

[0179] The judgment module 202 is used to determine whether fault handling of the temperature control equipment is required based on the target current parameters of the temperature control equipment.

[0180] The determination module 203 is used to determine the fault information of the temperature control equipment when it is determined that fault handling of the temperature control equipment is required.

[0181] The fault handling module 204 is used to perform fault handling operations on the temperature control device according to the fault information corresponding to the temperature control device.

[0182] It is evident that implementation Figure 2 The described device acquires the target current parameters of the temperature control equipment corresponding to the compressor during compressor operation; and determines whether fault handling of the temperature control equipment is required based on the target current parameters; when it is determined that fault handling of the temperature control equipment is required, it determines the corresponding fault information of the temperature control equipment and performs fault handling operations on the temperature control equipment based on the corresponding fault information, which can improve the fault handling efficiency and accuracy of the temperature control equipment, thereby enabling the temperature control equipment to return to normal or working state in a timely manner, and thus ensuring the working efficiency of the temperature control equipment.

[0183] In an optional embodiment, the specific method by which the determination module 202 determines whether fault handling of the temperature control device is required based on the target current parameters of the temperature control device includes:

[0184] When the target current parameter of the temperature control device includes the current pressure parameter of the temperature control device, determine whether the current pressure parameter of the temperature control device is used to indicate that the pressure switch of the temperature control device is open. When it is determined that the pressure switch of the temperature control device is open, it is determined that the temperature control device needs to be troubleshooted.

[0185] The specific methods by which the fault handling module 204 performs fault handling operations on the temperature control device based on the fault information corresponding to the temperature control device include:

[0186] When the duration of the pressure switch being disconnected by the temperature control device is detected to be greater than or equal to a predetermined duration threshold that matches the type of pressure switch, the compressor shutdown control parameters are determined, and the compressor is controlled to stop working according to the compressor shutdown control parameters.

[0187] When the pressure switch type of the temperature control device is the first switch type, the duration threshold value matched with the first switch type is a first duration threshold value; when the pressure switch type of the temperature control device is the second switch type, the duration threshold value matched with the second switch type is a second duration threshold value.

[0188] 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 value and the second duration threshold value are different from each other, for example, the duration threshold value matched with the first switch type can be 2 seconds, and the duration threshold value matched with the second switch type can be 3 minutes.

[0189] It can be seen that, by implementing the described device Figure 2 The described device can accurately generate corresponding control parameters by analyzing the duration when the high-pressure switch or the low-pressure switch is turned off, thereby accurately controlling the compressor.

[0190] In another optional embodiment, the specific manner in which the judging module 202 judges whether the temperature control device needs to be handled according to the target current parameter of the temperature control device includes:

[0191] When the target current parameter of the temperature control device includes the current exhaust parameter of the temperature control device, it is judged whether the current pressure parameter of the temperature control device indicates that the current exhaust temperature of the temperature control device is greater than or equal to a first preset exhaust temperature (for example, 90°C); when it is judged that the current exhaust temperature of the temperature control device is greater than or equal to the first preset exhaust temperature, it is determined that the temperature control device needs to be handled.

[0192] The specific manner in which the fault handling module 204 executes the fault handling operation on the temperature control device according to the fault information corresponding to the temperature control device includes:

[0193] When it is monitored that the current exhaust temperature of the temperature control device is greater than or equal to a second preset exhaust temperature (for example, 105°C), a frequency limiting control parameter of the compressor is generated, and the compressor is controlled to execute a frequency limiting operation according to the frequency limiting control parameter of the compressor, wherein the working frequency of the compressor after frequency limiting is lower than the working frequency before frequency limiting.

[0194] 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 DEG 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 an exhaust protection operation is performed on the temperature control device according to the exhaust protection control parameter of the temperature control device, specifically, hot gas is discharged from the compressor and its surroundings to reduce the temperature, and it should be noted that the compressor is in a shutdown state during the exhaust;

[0195] In the embodiment of the application, the first preset exhaust temperature is less than the second preset exhaust temperature, and the second preset exhaust temperature is less than the third preset exhaust temperature.

[0196] It can be seen that, in the embodiment of the application, Figure 2 The described device can effectively protect the device and prolong the service life of the device by segmenting the exhaust temperature of the temperature control device for the exhaust parameter type fault and accurately taking corresponding frequency limiting or exhaust operation in different stages.

[0197] In another optional embodiment, the specific manner in which the judging module 202 judges whether the temperature control device needs to be handled according to the target current parameter of the temperature control device includes:

[0198] When the target current parameter of the temperature control device includes the current coil temperature parameter of the temperature control device, it is judged whether the current coil temperature parameter of the temperature control device indicates whether the current indoor coil temperature of the temperature control device is greater than or equal to the first preset coil temperature, and when it is judged that the current indoor coil temperature of the temperature control device is greater than or equal to the first preset coil temperature (such as 50 DEG C), it is determined that the temperature control device needs to be handled.

[0199] The specific manner in which the fault handling module 204 performs the fault handling operation on the temperature control device according to the fault information corresponding to the temperature control device includes:

[0200] When it is monitored that the current indoor coil temperature of the temperature control device is greater than or equal to the second preset coil temperature (such as 59 DEG C), a frequency limiting control parameter of the compressor is generated, and the compressor is controlled to perform a frequency limiting operation according to the frequency limiting control parameter of the compressor, wherein the working frequency of the compressor after frequency limiting is lower than the working frequency before frequency limiting; and when it is monitored that the current exhaust temperature of the temperature control device is greater than or equal to the third preset coil temperature (such as 61 DEG C) for a duration greater than or equal to the second preset duration, an over-temperature protection control parameter of the temperature control device is generated, and an over-temperature protection operation is performed on the temperature control device according to the over-temperature protection control parameter of the temperature control device, specifically, the compressor is controlled to be shut down, and further, the coil is subjected to heat dissipation treatment.

[0201] The first preset coil temperature is less than the second preset coil temperature, and the second preset coil temperature is less than the third preset coil temperature. In the embodiment of the present application, 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 the temperature control device does not need to be handled.

[0202] It can be seen that, in the embodiment of the present application, Figure 2 The described device can monitor the coil temperature in real time for coil type faults, limit the frequency first and then stop the machine for over-temperature protection when different node temperatures are monitored, that is, through the progressive fault handling judgment and processing links, the temperature control device can be effectively protected while working, and the occurrence of coil or other component damage due to high temperature can be reduced, which is beneficial to prolong the service life of the device.

[0203] In another optional embodiment, when the target current parameter of the temperature control device includes the input current of the driving module of the compressor and / or the phase current of the driving module of the compressor, the target current parameter of the temperature control device includes the input current of the driving module of the compressor and / or the phase current of the driving module of the compressor.

[0204] The specific way in which the judgment module 202 judges whether the temperature control device needs to be handled according to the target current parameter of the temperature control device includes:

[0205] When it is determined that the current current parameter of the temperature control device is an abnormal current parameter, it is determined that the temperature control device needs to be handled.

[0206] The specific way in which the fault handling module 204 executes the fault handling operation on the temperature control device according to the fault information corresponding to the temperature control device includes:

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

[0208] When it is monitored that the driving module compressor phase current of the compressor is greater than or equal to a 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 working frequency of the compressor after frequency limiting is lower than the working frequency before frequency limiting; when it is monitored that the driving module compressor phase current of the compressor is greater than or equal to a 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.

[0209] The third preset current is less than the fourth preset current, the fourth preset current is less than the first preset current, and the first preset current is less than the second preset current.

[0210] It can be seen that the apparatus described in the embodiment Figure 2 The described apparatus can control the current protection accurately under different conditions by controlling the frequency limiting and protection of the temperature control device according to the input current and the compressor phase current fed back by the driving module of the compressor.

[0211] In another optional embodiment, as Figure 3 shown in the figure, the apparatus can further include:
