Referring to FIG. 2, FIG. 2 is a schematic flowchart of a first embodiment of a method for checking faults of an air conditioner according to the present application.

This embodiment provides a method for checking the failure of an air conditioner, and the method for checking the failure of the air conditioner includes:

S10, it is determined that an instruction to enter the spot inspection mode is received, and the fault information stored in the non-volatile memory of the air conditioner is obtained;

S20: Control the display device of the air conditioner to display the fault information, so as to perform fault point inspection on the air conditioner.

In an embodiment, the air conditioner acquires the fault information stored in the non-volatile memory of the air conditioner when receiving the instruction of the check mode. Among them, the instruction of the check mode can be generated by its own control device, or generated by a remote control paired with the air conditioner, or generated by a terminal device communicatively connected with the air conditioner, which is not limited here.

In one embodiment, when the instruction of the check mode is generated by the remote control, that is, by setting a specific operation on the remote control, such as long pressing the power button, etc., the remote control generates a command to control the air conditioner to enter the check mode. At this time, the remote controller sends the instruction to the air conditioner, and when the air conditioner receives the instruction to enter the check mode, the fault information stored in the non-volatile memory is obtained. Among them, the remote controller can send instructions to the air conditioner through wireless transmission methods including but not limited to WIFI, Bluetooth, infrared, etc. Or, when the instruction of the check mode is generated by a terminal device, that is, the terminal device is equipped with a corresponding APP (Application, application), the user can select the button to enter the check mode on the APP operation interface. When the time, the terminal device will generate an instruction to control the air conditioner to enter the check mode, and send the instruction to the air conditioner. When the air conditioner receives the instruction to enter the check mode, it will obtain the fault information stored in the non-volatile memory . Among them, the remote controller can send instructions to the air conditioner through wireless transmission methods including but not limited to WIFI, Bluetooth, infrared, etc.

In one embodiment, a non-volatile memory (NVM) is a memory that does not disappear when the air conditioner is shut down or the air conditioner is powered off. Among them, non-volatile memory includes ROM (Read-only memory), PROM (Programmable read-only memory), EAROM (Electrically alterable read only memory), EPROM (Erasable programmable read only memory), EEPROM (Electrically erasable programmable read-only memory), or Flash memory (flash memory), here is also Unlimited.

Further, after obtaining the fault information stored in the non-volatile memory of the air conditioner, the display device of the air conditioner is controlled to display the fault information, so as to perform a fault spot check on the air conditioner. Wherein, the display device of the air conditioner is a display panel nixie tube installed on the air conditioner. After the fault information is obtained, the fault information is displayed on the display panel nixie tube, so as to carry out all the faults of the air conditioner.

Or, when the air conditioner controls the display device of the air conditioner to display the fault information, and displays the fault information through the display device, the air conditioner sends the fault information to the terminal device paired with it to display the fault information on the terminal device APP The display interface shows the fault information.

Specifically, when an instruction to enter the spot inspection mode is received, the non-volatile memory sequentially reads the fault information, and controls the display device of the air conditioner to display the read fault information. Since the non-volatile memory is a memory that is not lost after power failure, you can read all the stored fault information from the non-volatile memory. When all the fault information is read, the display device is controlled to display the read fault information.

In one embodiment, when the display device displays the fault information, the display parameters of the display device are first acquired, and the display device of the air conditioner is controlled to display the read fault information according to the display parameters. Wherein, the display parameters include the display time of the fault information, that is, after the fault information is obtained, the display device is determined to display the display time of the fault information. For example, the display time of the fault information is 0.5s, that is, the fault information is displayed there. 5s is displayed on the display device. It is understandable that the display time of the fault information can be other values, for example, 0.25s, etc., which is not limited here.

In an embodiment, when there are multiple fault information, the display parameter also includes the interval time between two adjacent fault information. In this embodiment, the interval time may also be 0.5s, that is, the first After the fault information is displayed in the display device for 0.5s, the display device is turned off for 0.5s, and then the display device displays the second fault information. At this time, the display time of the second fault information is also 0.5s, and so on, until all The fault information is displayed. Of course, in other embodiments, the display parameters may also be display frequency, display brightness, etc., which are not limited here.

In one embodiment, when performing fault point inspection, because when there are too many fault information, it is necessary to record the fault information displayed by the display device for diagnosis and maintenance, that is, there may be errors or omissions in the fault information recording. In this embodiment, the display device that controls the air conditioner periodically displays the fault information in cycles according to the display parameters, wherein after each display period is completed, the display device is controlled to turn off the screen for a preset period of time, that is, when After the display device displays all the fault information, the display device turns off the screen for a preset time, and when the preset time meets the preset conditions, the fault information is displayed again to record the fault information and ensure the accuracy of the fault information.

Further, the preset time length is set by the user, or confirmed according to the interval time of the air conditioner failure information. At this time, in order to distinguish the preset time length and the interval time, the preset time length can be set to a time that is inconsistent with the interval time, such as When the interval time is also 0.5s, the preset duration can be set to 4s, so that the preset duration is greater than the interval time, that is, when the extinguishing time of the display device reaches 4s, the display device is controlled to perform the next cycle. The fault information is displayed cyclically to ensure the accuracy of the fault information.

In the embodiment of the present application, the method for checking the failure of the air conditioner includes the following steps: determining that an instruction to enter the check mode is received, obtaining the failure information stored in the non-volatile memory of the air conditioner; and controlling the air conditioner The display device of the air conditioner displays the fault information to perform fault point inspection on the air conditioner, that is, by storing the fault information in a non-volatile memory, and performing display point inspection on all the fault information, so as to facilitate the fault detection. Diagnose and repair.

Further, referring to FIG. 3, a second embodiment of the present application is proposed based on the first embodiment. In this embodiment, before the step of receiving the instruction to enter the check mode, the fault check method of the air conditioner is also include:

S30: Determine that a failure of the air conditioner is detected, and obtain failure information corresponding to the failure;

S40: Store the fault information in a non-volatile memory of the air conditioner.

Before the air conditioner receives the instruction to enter the check mode, the air conditioner operates in a normal cooling or normal heating mode, and detects whether the air conditioner is malfunctioning during the operation of the air conditioner, and determines that the air conditioner is detected When a fault occurs, obtain fault information corresponding to the fault; store the fault information in the non-volatile memory of the air conditioner.

In an embodiment, the fault information includes, but is not limited to, fault code, fault name, power-on time, closing time of outdoor relays, cumulative running time of indoor fans, cumulative running time of compressors, and cumulative power-on time of negative ions. One or more. Among them, the power-on time is the cumulative power-on time of the power supply when a fault occurs; the outdoor relay closing time is the cumulative connection time of the indoor unit and the outdoor unit when the fault occurs; the cumulative power-on time of the negative ion is the cumulative power-on time after the power-on condition is met after the air cleaning is turned on . Or, for a model where the air conditioner is cleaning the filter, the fault information also includes the number of times the filter is cleaned when the fault occurs.

Further, since there is more than one failure caused by the operation of the air conditioner, that is, when there are multiple failure information, the time points at which the multiple failure information occurs are acquired, that is, the time sequence of the occurrence of the air conditioner failure can be confirmed through the time points; Sort each of the fault information according to the order of the time point to obtain a sorting result, and sequentially store a plurality of the fault information in the non-volatile memory of the air conditioner according to a preset rule and the sorting result in.

Specifically, the sorting result is that the latest fault information is ranked first, that is, the first fault information at the time point is ranked first. For example, the air conditioner has the first failure at 14:00, the second failure at 15:20, and the third failure at 15:40, that is, the sorting result is the failure information corresponding to the third failure, the second failure The fault information corresponding to the second fault, the fault information corresponding to the first fault, and so on, the latest fault information is ranked first, and the position of the remaining fault information is shifted by one place.

Specifically, the preset rule is that the Nth fault information is stored in the Nth storage address, where N is a positive integer greater than or equal to 1, that is, the first fault information is stored in the first storage address , The second fault information is stored in the second storage address, so as to store all the fault information in the non-volatile memory of the air conditioner.

Further, when the display device displays the fault information, the first fault information displayed by the display device is the fault information of the first storage address, that is, the display device preferentially displays the latest fault information, and so on, the display device is based on the fault information. The display time and interval time are displayed on the display device for maintenance personnel to check.

Specifically, the step of sequentially storing a plurality of the fault information in the non-volatile memory of the air conditioner according to the preset rule and the sorting result includes: obtaining the storage of the non-volatile memory Address; if the number of fault information is greater than the storage space of the storage address, delete the corresponding fault information first stored in the storage address, and reorder the remaining fault information with the latest fault information, in accordance with the reordering As a result, the fault information is sequentially stored in the non-volatile memory of the air conditioner; if the number of the fault information is less than or equal to the storage space of the storage address, execute the sorting result according to the The step of storing the fault information in the non-volatile memory of the air conditioner.

Further, the space for storing the fault information in the non-volatile memory is preset, that is, the storage space of the non-volatile memory is divided into multiple sections, for example, the storage space of the non-volatile memory is divided into the storage space for storing the fault information. The first interval and the second interval for storing other information, but in other embodiments, the storage space of the non-volatile memory can also be divided into a third interval, a fourth interval, etc., depending on the specific function settings of the memory, There is no limit here.

Further, after the intervals are divided, the storage address of the storage interval of the fault information is confirmed. For example, when the storage interval of the fault information is the first interval, the storage address of the first interval is confirmed; in this embodiment, the The storage space of the storage address of the storage area of the fault information is set to five, namely "Address 1", "Address 2", "Address 3", "Address 4" and "Address 5", or the storage of the fault information The storage address of the interval is set to other values, which is not limited here. Of course, it can be understood that the naming of "Address 1", "Address 2", "Address 3", "Address 4", and "Address 5" is only for the convenience of describing the embodiment, and is not a technical solution to this embodiment. The limit.

Further, if the number of the fault information is greater than the storage space of the storage address, the corresponding fault information first stored in the storage address is deleted, and the remaining fault information is reordered with the latest fault information, according to the reordering As a result of the sorting, the fault information is sequentially stored in the non-volatile memory of the air conditioner. For example, when there are six fault messages, they are named "fault 6", "fault 5", "fault 4", "fault 3", "fault 2", and "fault 1" in the order of the point in time when the fault occurred. At this time, because the storage space of the storage address is five, that is, "fault 5" is stored to "address 1," "fault 4" is stored to "address 2", and "fault 3" is stored to "Address 3" and "Fault 2" are correspondingly stored in "Address 4", and "Fault 1" is correspondingly stored in "Address 5". At this time, delete the corresponding fault information stored in the storage address first, that is, delete "Fault 1,", and reorder "Fault 6", "Fault 5", "Fault 4", "Fault 3" and "Fault 2", and store the sorted fault information in order in the air conditioner In the non-volatile memory, "fault 6" is correspondingly stored to "address 1," "fault 5" is stored to "address 2", "fault 4" is stored to "address 3", and "fault 3" is corresponding Stored to "Address 4", "Fault 2" is correspondingly stored to "Address 5", so that the non-volatile memory records the latest preset number of fault information.

Further, if the quantity of the fault information is less than or equal to the storage space of the storage address, the step of storing the fault information in the non-volatile memory of the air conditioner according to the sorting result is performed.

In this way, the technical solution provided by the present application can ensure that the non-volatile memory saves the preset number of latest fault information, so as to monitor and diagnose the fault of the air conditioner in real time.

Further, referring to FIG. 4, a third embodiment of this application is proposed based on the first embodiment. In this embodiment, the method for checking the failure of the air conditioner further includes:

S50: Determine the quantity of the fault information stored in the non-volatile memory of the air conditioner;

If the quantity of the fault information meets the preset quantity, the step of S20 is executed.

In this embodiment, the preset number is zero. When the number of the fault information stored in the non-volatile memory of the air conditioner meets the preset number, that is, when the non-volatile memory of the air conditioner stores When the number of the fault information is greater than zero, the display device of the air conditioner is controlled to display the fault information, so as to perform a fault spot check on the air conditioner.
