[0023] It should be noted that, without conflict, different features in the embodiments of the present invention can be combined with each other.

[0024] To solve the technical problems mentioned in the foregoing background art, the inventor innovatively designs the following technical solutions. The specific implementation solutions of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] Please refer to Figure 1 , Figure 1 Schematic diagram of the step flow of the fault prompt method provided in an embodiment of the present invention. This method is applied to Figure 3The refrigeration device 100 shown includes a variable frequency board 110, a compressor 120, and a fault prompt module 130. The compressor 120 and the fault prompt module 130 are respectively connected to the variable frequency board 110. The following will be directed at Figure 1 the process shown will be elaborated in detail. The fault prompt method may specifically include the following steps:

[0026] Step S110: Detect whether the compressor fails. When it is detected that the compressor fails, obtain the duration of the compressor fault through the variable frequency board as the first duration.

[0027] Among them, the compressor compresses the refrigerant to drive the refrigerant to circulate in the refrigeration device to achieve refrigeration of the refrigeration device. Therefore, when the compressor fails, it will affect the refrigeration efficiency of the refrigeration device. Since the compressor is connected to the variable frequency board, when the compressor fails, the variable frequency board will receive abnormal information from the compressor, and the variable frequency board will determine whether the compressor fails according to the abnormal information. The abnormal information can be an abnormal identifier or data in an abnormal range in the compressor. The specific definition of the abnormal data is not limited here.

[0028] Furthermore, when the variable frequency board obtains the abnormal information sent by the compressor, it can determine that the compressor fails and will obtain the duration of the compressor fault. The obtaining method of the duration of the compressor fault can be that the variable frequency board starts timing from the moment it receives the abnormal information until there is no abnormal information in the compressor information, so as to determine the duration of the compressor fault. The obtaining method of the duration of the compressor fault can also be that the compressor records the duration of the fault and sends the duration to the variable frequency board. The specific definition of the obtaining method of the variable frequency board to obtain the duration of the compressor fault is not limited here.

[0029] Step S120: If the first duration is greater than or equal to the first duration threshold corresponding to the first duration, determine that this fault is a persistent fault, and the variable frequency board sends a first prompt instruction corresponding to the persistent fault to the fault prompt module, so that the fault prompt module performs fault prompting according to the first prompt instruction.

[0030] Among them, the first duration threshold can be preset or customized. The first duration threshold can be 1h, can also be 30min, or can also be 2h. The specific definition of the first duration threshold is not limited here.

[0031] Furthermore, the fault prompt module may include but is not limited to a voice prompt module, an indicator light, and a display screen. The prompting method of the fault prompt can be only voice prompting, can also be only light flashing prompting, can also be only abnormal information display on the display screen, or can also be multiple prompting methods at the same time. The specific definition of the prompting method of the fault prompt module is not limited here.

[0032] The first prompt instruction is used to instruct the fault prompt module to perform fault prompting. The first prompt instruction includes, but is not limited to, a voice prompt instruction, a light flashing instruction, and a display instruction. The fault prompt module performs fault display according to the first prompt instruction.

[0033] Step S130: If the first duration is less than the first duration threshold, it is determined that the current fault is a transient fault, and the frequency conversion board sends a second prompt instruction corresponding to the transient fault to the fault prompt module, so that the fault prompt module performs fault prompting according to the second prompt instruction.

[0034] Wherein, the second prompt instruction may be the same as the first prompt instruction or different from the first prompt instruction, and no specific limitation is made here.

[0035] In the embodiment of the present invention, to distinguish the fault categories, the first prompt instruction and the second prompt instruction need to be set as different instructions. Exemplarily, when the first prompt instruction is a voice prompt instruction, the second prompt instruction may be a light flashing instruction, a display instruction, or a combination of a voice prompt instruction and a light flashing instruction.

[0036] In an implementation manner of the present invention, the fault prompt module includes an indicator light and a display screen. The first prompt instruction includes a light flashing instruction and a fault identification display instruction, and the second prompt instruction includes a light flashing instruction. If the first duration is greater than or equal to the first duration threshold corresponding to the first duration, it is determined that the current fault is a persistent fault, and the frequency conversion board sends a first prompt instruction corresponding to the persistent fault to the fault prompt module, so that the fault prompt module performs fault prompting according to the first prompt instruction. The steps include: If the first duration is greater than or equal to the first duration threshold corresponding to the first duration, it is determined that the current fault is a persistent fault, and the frequency conversion board sends a light flashing instruction and a fault identification display instruction to the fault prompt module, so that the indicator light in the fault prompt module flashes according to the light flashing instruction, and a fault identification corresponding to the persistent fault is displayed on the display screen. If the first duration is less than the first duration threshold, it is determined that the current fault is a transient fault, and the frequency conversion board sends a second prompt instruction corresponding to the transient fault to the fault prompt module, so that the fault prompt module performs fault prompting according to the second prompt instruction. The steps include: If the first duration is less than the first duration threshold, it is determined that the current fault is a transient fault, and the frequency conversion board sends a light flashing instruction to the fault prompt module, so that the fault prompt module flashes according to the light flashing instruction.

[0037] Wherein, the fault identification may be a preset one or a custom identification, and no specific limitation is made on the fault identification here.

[0038] In this embodiment, the fault prompt module includes an indicator light and a display screen. To distinguish between persistent faults and transient faults, at this time, the first prompt instruction is the light flashing instruction and the fault identification display instruction, while the second prompt instruction is the light flashing instruction. When it is determined that the fault of the compressor is a persistent fault, the variable frequency board sends the first prompt instruction to the fault prompt module, so that the indicator light of the fault prompt module flashes, and the fault identification corresponding to the persistent fault is displayed on the display screen of the fault prompt module. When it is determined that the fault of the compressor is a transient fault, the variable frequency board sends the second prompt instruction to the fault prompt module, so that the indicator light of the fault prompt module flashes. Thus, it is convenient to distinguish the fault categories of the compressor according to the prompt method of the fault prompt module, and the efficiency of fault repair is improved.

[0039] In another embodiment of the present invention, the fault prompt module includes a voice module, and the first prompt instruction includes a voice instruction. If the first duration is greater than or equal to the first duration threshold corresponding to the first duration, it is determined that the current fault is a persistent fault, and the variable frequency board sends the first prompt instruction corresponding to the persistent fault to the fault prompt module, so that the fault prompt module performs fault prompt according to the first prompt instruction, including: if the first duration is greater than or equal to the first duration threshold corresponding to the first duration, it is determined that the current fault is a persistent fault, and the variable frequency board sends a voice instruction to the fault prompt module, so that the voice module in the fault prompt module performs voice prompt according to the voice instruction.

[0040] Among them, the voice prompt can prompt the fault category, can also prompt the occurrence of a fault, can also prompt fault information such as the location and time of the fault occurrence, etc. The voice prompt corresponding to the persistent fault can be the same as or different from the voice prompt of the transient fault. The voice prompt can be customized according to requirements, and the voice prompt is not specifically limited here. Preferably, the voice prompt corresponding to the persistent fault is different from the voice prompt corresponding to the transient fault to facilitate distinguishing the fault categories.

[0041] In this embodiment, the fault prompt module includes a voice module. When the variable frequency board determines that the compressor has a fault, it will send a voice instruction to the fault prompt module, so that the fault prompt module performs voice prompt according to the voice instruction.

[0042] The solution provided by the present invention, when the variable frequency board detects that the compressor of the refrigeration equipment has a fault, will classify the fault according to the duration of the fault, so that the fault prompt module performs fault prompt according to the prompt instructions corresponding to different categories of faults, thereby improving the efficiency of fault repair.

[0043] Please refer to Figure 2 , Figure 2 which is the step flow schematic diagram of the fault prompt method provided by another embodiment of the present invention. Next, it will be directed to Figure 2The following is a detailed description of the process shown. The fault prompt method may specifically include the following steps:

[0044] Step S210: Obtain the power-on duration of the refrigeration device as the second duration.

[0045] Among them, the power-on duration refers to the cumulative operation duration of the refrigeration device from when the power is turned on to the current moment.

[0046] Step S220: If the second duration is greater than or equal to the second duration threshold corresponding to the second duration, and when it is detected that the compressor fails, the variable frequency board sends a restart command to the refrigeration device.

[0047] Step S230: After the refrigeration device restarts based on the restart command, obtain the power-on duration after the restart of the refrigeration device through the variable frequency board, and use the power-on duration as the second duration.

[0048] In the embodiment of the present invention, when the second duration is greater than or equal to the second duration threshold, it indicates that the refrigeration device has been working continuously for a period of time. At this time, the detected compressor failure may be an error caused by the long-term operation of the refrigeration device. To eliminate this error, the variable frequency board sends a restart command to the refrigeration device to make it restart. After the refrigeration device restarts, the power-on duration after the restart will be used as the new second duration to re-detect whether the compressor fails according to the second duration, thus ensuring the accuracy of the compressor failure information and improving the detection accuracy of the compressor failure detection.

[0049] Step S240: When the second duration is less than the second duration threshold, and when it is detected that the compressor fails, obtain the continuous duration of the compressor failure through the variable frequency board as the first duration.

[0050] Step S250: If the first duration is greater than or equal to the first duration threshold corresponding to the first duration, determine that this failure is a persistent failure, and the variable frequency board sends the first prompt command corresponding to the persistent failure to the fault prompt module, so that the fault prompt module performs fault prompt according to the first prompt command.

[0051] Step S260: If the first duration is less than the first duration threshold, determine that this failure is a transient failure, and the variable frequency board sends the second prompt command corresponding to the transient failure to the fault prompt module, so that the fault prompt module performs fault prompt according to the second prompt command.

[0052] In the embodiment of the present invention, when the second duration is less than the second duration threshold, it indicates that the refrigeration device has been working for a short time. At this time, when the compressor fails, the specific processing method for the compressor failure in steps S110 to S130 in the foregoing embodiment can be referred to, and details are not described herein again.

[0053] Step S270: When the second duration is greater than or equal to the second duration threshold, the variable frequency board sends a fault prompt cancellation instruction to the fault prompt module, so that the fault prompt module no longer performs fault prompts.

[0054] In the embodiment of the present invention, when the second duration is greater than or equal to the second duration threshold, it indicates that the fault prompt of the fault prompt module lasts for a long time. To improve the judgment accuracy of other faults in the refrigeration equipment, it is necessary to cancel this fault prompt. Therefore, the variable frequency board sends a fault prompt cancellation instruction to the fault prompt module, so that the fault prompt module no longer performs fault prompts.

[0055] Step S280: Update the fault information recorded in the variable frequency board, and update the fault information recorded in the variable frequency board to the fault information corresponding to this fault.

[0056] Among them, the fault information includes but is not limited to information such as the fault occurrence time, fault occurrence location, fault duration, and conventional solutions corresponding to the fault. The fault information is not specifically limited here.

[0057] In the embodiment of the present invention, to facilitate the user to repair the fault, the variable frequency board will record the most recent or several recent or even all fault information for the user to view. Preferably, the variable frequency board will record the most recent fault information. When a new fault occurs, the recorded fault information will be updated to the fault information corresponding to the new fault.

[0058] In an embodiment of the present invention, the variable frequency board receives a fault information viewing instruction for viewing fault information, and based on the fault information viewing instruction, displays the fault information recorded in the variable frequency board.

[0059] Among them, the fault information viewing instruction can be a viewing button instruction on the refrigeration equipment, or a remote viewing instruction, or a voice viewing instruction. The fault information viewing instruction is not specifically limited here.

[0060] In a specific embodiment of the present invention, the fault information viewing instruction includes a viewing button instruction on the refrigeration equipment. The variable frequency board receives the viewing button instruction and, based on the viewing button instruction, displays the fault information recorded in the variable frequency board.

[0061] Among them, the viewing button instruction refers to a button instruction set on the refrigeration equipment for triggering the viewing of fault information. The button instruction can be triggered by a single button or by a combination of multiple buttons. The viewing button instruction is not specifically limited here. Exemplarily, the refrigeration equipment has a button for increasing the temperature "+" and a button for decreasing the temperature "-". The viewing button instruction can be triggered by the "+" key, or by the "-" key, or by the simultaneous triggering of the "+" key and the "-" key.

[0062] When the viewing button instruction is triggered by pressing a button, the variable frequency board receives the viewing button instruction and displays the fault information recorded in the variable frequency board based on the viewing button instruction, so as to perform maintenance according to the fault information.

[0063] In another specific embodiment of the present invention, the fault information viewing instruction includes a remote viewing instruction of the terminal. The variable frequency board receives the remote viewing instruction and sends the fault information recorded in the variable frequency board to the terminal based on the remote viewing instruction, so that the terminal displays the fault information recorded in the variable frequency board.

[0064] Among them, the terminal refers to a device with data transceiver function. The terminal can be a mobile phone, a computer, a tablet, etc. The terminal is not specifically limited here. It should be noted that for the variable frequency board to receive the remote viewing instruction sent by the terminal, the refrigeration device needs to establish communication with the terminal first. The communication method can be Bluetooth communication or wireless network (Wireless Fidelity, WiFi) communication. The communication method is not specifically limited here.

[0065] After the variable frequency board establishes communication with the terminal, it can receive the remote viewing instruction sent by the terminal. The variable frequency board sends the recorded fault information to the terminal based on the remote viewing instruction, so that users can remotely view the fault information and master the status of the refrigeration device.

[0066] The solution provided by the present invention, when the variable frequency board detects that the compressor of the refrigeration device fails, classifies the fault according to the duration of the fault, so that the fault prompt module performs fault prompts according to the prompt instructions corresponding to different types of faults, thereby improving the maintenance efficiency of the fault. Moreover, to facilitate users to view historical fault information, the variable frequency board also records the fault information, reducing the troubleshooting time during the maintenance of the refrigeration device.

[0067] Based on the same inventive concept, please refer to Figure 3 , Figure 3 is a schematic diagram of the functional modules of a refrigeration device 100 provided in this embodiment. This embodiment can divide the functional modules of the refrigeration device 100 according to the above method embodiment. For example, each functional module can be divided corresponding to each function, or two or more functions can be integrated into one processing module. The above integrated module can be implemented in the form of hardware or in the form of a software functional module. It should be noted that the division of modules in the embodiments of the present invention is illustrative, only a logical function division, and there can be other division methods in actual implementation. For example, in the case of dividing each functional module corresponding to each function, Figure 3The refrigeration device 100 shown is only a schematic diagram of a device. The refrigeration device 100 includes a variable frequency board 110, a compressor 120, and a fault prompt module 130. The compressor 120 and the fault prompt module 130 are respectively connected to the variable frequency board 110. The functions of each functional module of this fault prompt device will be elaborated in detail below.

[0068] The variable frequency board 110 is used to detect whether the compressor 120 fails. When it detects that the compressor 120 fails, the variable frequency board 110 is used to obtain the duration of the compressor 120's failure and use the duration as the first duration. If the first duration is greater than or equal to the first duration threshold corresponding to the first duration, it is determined that this failure is a persistent failure, and the variable frequency board 110 is used to send a first prompt instruction corresponding to the persistent failure to the fault prompt module 130. If the first duration is less than the first duration threshold, it is determined that this failure is a transient failure, and the variable frequency board 110 is used to send a second prompt instruction corresponding to the transient failure to the fault prompt module 130.

[0069] The fault prompt module 130 is used to receive the first prompt instruction and the second prompt instruction sent by the variable frequency board 110 and perform fault prompting according to the first prompt instruction and the second prompt instruction.

[0070] Furthermore, an embodiment of the present invention also provides a computer storage medium storing an executable program. When the executable program is executed, it can be used to implement the fault prompt method provided in the above method embodiment.

[0071] Of course, for a computer storage medium containing an executable program provided by an embodiment of the present invention, its executable program is not limited to the above method operations, and can also execute related operations in the fault prompt methods provided by any embodiment of the present invention.

[0072] In summary, the present invention provides a fault prompt method and a refrigeration device. The fault prompt method is applied to a computer device in a fault prompt system. First, a motion sensor in the fault prompt system detects the motion information of a mechanical device at a preset time interval, then determines the corresponding motion state according to the motion information, and then compares the motion states of two adjacent times. When the motion states of two adjacent times are inconsistent, the number of over-limit motions is accumulated. When the number of over-limit motions exceeds the preset number of over-limit motions, the motion states of two adjacent times are detected within the next timing duration. If they are inconsistent, the cumulative trigger duration is accumulated. When the cumulative trigger duration is greater than the delay trigger duration, an emergency stop signal is triggered. Through the above method, the over-limit vibration of the mechanical device can be captured in time and an emergency stop signal can be issued to prevent the occurrence of vibration instability. At the same time, the setting of trigger delay is provided to avoid false triggering during the normal operation of the device.
