Description

TECHNICAL FIELD

[0001] The present application relates to the field of air conditioning technology, in particular to a control method of an air conditioner and the air conditioner. BACKGROUND

[0002] When the existing air conditioner works in a special environment, for example, works in an ultra-low temperature environment (the outdoor temperature is-26℃ and below-26℃), the low temperature causes the frequency of the compressor to be low in a short time when the compressor is just started, so that the low pressure of the compressor is less than the preset minimum value. At this time, the compressor will report a low pressure fault warning, which affects the normal start of the compressor. In order to solve the above problem, the designer usually stores a low pressure shielding program in the air conditioner control program to shield the low pressure fault warning when the compressor is just started, so as to ensure the normal operation of the compressor. However, if the designer forgets to store the low pressure shielding program in the air conditioner control program, when the air conditioner reports a low pressure fault warning in the subsequent process, it is difficult for the experimenters and maintenance personnel to determine whether the air conditioner indoor unit stores the low pressure shielding program, so that the experimenters and maintenance personnel cannot judge whether the hardware of the air conditioner fails or the control program fails in a short time, which makes the troubleshooting range large and the troubleshooting difficult, and the time required for troubleshooting is also long, and the maintenance efficiency is low.

[0035] The following detailed description will be made with reference to the accompanying drawings. Figures 1 to 5The application discloses a control method of an air conditioner and the air conditioner.

[0036] Figure 1 Fig. 1 is a schematic flow chart of a control method of an air conditioner according to an embodiment of the application, as shown in the figure, the embodiment of the application provides a control method of an air conditioner, which comprises the following steps: Figure 1

[0037] Step S1: judging whether the air conditioner can normally operate;

[0038] Step S2: if yes, it is determined that the air conditioner stores a low-pressure shielding program, and the low-pressure shielding program is used for shielding shutdown or abnormal operation of the air conditioner caused by low pressure when the air conditioner is started;

[0039] Step S3: if no, judging whether the air conditioner stores the low-pressure shielding program according to a fault occurred in the air conditioner.

[0040] Specifically, as to the step S1, it needs to be explained that in some special cases, for example, in an ultralow-temperature environment, whether the air conditioner can normally operate can reflect whether the air conditioner stores the low-pressure shielding program to a certain extent, and it can also be understood that whether the air conditioner can normally operate can reflect whether the low-pressure shielding program stored in the air conditioner is invalid to a certain extent;

[0041] As to the step S2, it needs to be explained that if the air conditioner can normally operate, it indicates that the air conditioner stores the low-pressure shielding program or the low-pressure shielding program stored in the air conditioner is not invalid, so it is determined that the air conditioner stores the low-pressure shielding program or the low-pressure shielding program stored in the air conditioner is not invalid;

[0042] As to the step S3, it needs to be explained that if the air conditioner cannot normally operate, it indicates that the air conditioner has a fault, but the fault of the air conditioner can be caused by abnormality of the low-pressure shielding program or caused by other reasons, so it is necessary to further judge whether the air conditioner stores the low-pressure shielding program according to the fault occurred in the air conditioner.

[0043] The setting method of the embodiment of the application adds the control logic for judging whether the low-pressure shielding program exists in the air conditioner, judges whether the air conditioner stores the low-pressure shielding program according to whether the air conditioner can normally operate and according to the fault occurred in the air conditioner, and feeds back the judgment result, so that the experiment personnel and the maintenance personnel can know whether the air conditioner stores the low-pressure shielding program in a short time, and then do not need to check the low-pressure shielding program when checking the fault of the air conditioner, which not only reduces the checking difficulty of the air conditioner fault, but also reduces the checking range of the fault and shortens the time required for checking the fault, and improves the maintenance efficiency.

[0044] ​In some embodiments of the present application, the determining whether the air conditioner can operate normally includes: determining whether the air conditioner can operate normally within a preset time period after the air conditioner is started. Specifically, in some special application scenarios, for example, in an ultra-low temperature environment, the air frequency of the compressor of the air conditioner is low in a short time after the air conditioner is started, which causes the air conditioner to generate a low pressure fault. Therefore, the determination whether the air conditioner can operate normally within a preset time period after the air conditioner is started makes the determination result of whether the low pressure shielding program is accurate.

[0045] In some embodiments of the present application, the preset time is 10 minutes to 20 minutes.

[0046] As shown in FIG. 1, Figure 2 In some embodiments of the present application, the determining whether the air conditioner stores the low pressure shielding program according to the fault of the air conditioner includes:

[0047] Step S31: determining whether the fault of the air conditioner is a low pressure fault;

[0048] Step S32: if yes, it is determined that the air conditioner does not store the low pressure shielding program, and a first determination result is obtained; the first determination result is fed back, and the first determination result includes that the air conditioner does not store the low pressure shielding program;

[0049] Step S33: if no, it is determined that the air conditioner stores the low pressure shielding program, and a second determination result is obtained; the second determination result is fed back, and the second determination result includes that the air conditioner has other faults except that the air conditioner does not store the low pressure shielding program.

[0050] Specifically, regarding the step S32, it should be noted that if the fault of the air conditioner is a low pressure fault, it means that the air conditioner does not store the low pressure shielding program, or the low pressure shielding program stored in the air conditioner is invalid. Then the air conditioner obtains the first determination result based on the above situation and feeds back the first determination result.

[0051] Such setting can enable the experimenters and maintenance personnel to further investigate and maintain the air conditioner based on the fault that the air conditioner does not store the low pressure shielding program or based on the fault that the low pressure shielding program is invalid after receiving the first determination result, accurately investigate the range of the experimenters and maintenance personnel, and improve the maintenance efficiency.

[0052] It is to be noted that, if the fault of the air conditioner is not the low-pressure fault, it indicates that the air conditioner stores the low-pressure shielding program or the low-pressure shielding program stored in the air conditioner is still effective to shield the shutdown or abnormal operation of the air conditioner due to the low pressure at the start-up; but at this time, since the air conditioner still has the fault, it indicates that the air conditioner has other faults except the low-pressure fault, and the air conditioner obtains the first determination result based on the above situation and feeds back the first determination result.

[0053] In this way, after receiving the second determination result, the experimenters and the maintenance personnel can exclude the fault that the air conditioner does not store the low-pressure shielding program or the fault that the low-pressure shielding program is invalid, and further check other faults, so as to narrow the checking range of the experimenters and the maintenance personnel, reduce the difficulty of fault checking, and improve the efficiency of fault checking.

[0054] In some embodiments of the present application, after determining that the air conditioner stores the low-pressure shielding program, the method further comprises:

[0055] When the air conditioner has the fault, the third determination result is obtained; and the third determination result is fed back, and the third determination result comprises: the air conditioner has other faults except that the air conditioner does not store the low-pressure shielding program.

[0056] Specifically, in the subsequent work of the air conditioner, there is also a possibility of fault, and the fault of the air conditioner may be a low-pressure fault or other faults except the low-pressure fault.

[0057] When the fault of the air conditioner is the low-pressure fault, since the air conditioner stores the low-pressure shielding program, based on the above situation, the air conditioner obtains the third determination result and feeds back the third determination result.

[0058] In this way, after receiving the third determination result, the experimenters and the maintenance personnel can exclude the fault that the air conditioner does not store the low-pressure shielding program or the fault that the low-pressure shielding program is invalid, and further check the low-pressure fault, for example, check whether the low-pressure switch of the compressor of the air conditioner can work normally; so as to narrow the checking range of the experimenters and the maintenance personnel, reduce the difficulty of fault checking, and improve the efficiency of fault checking.

[0059] When the fault of the air conditioner is the low-pressure fault, since the air conditioner stores the low-pressure shielding program, based on the above situation, the air conditioner obtains the third determination result and feeds back the third determination result.

[0060] This setup allows testing and maintenance personnel to rule out the possibility that the air conditioner has not stored a low-pressure shielding program or that the low-pressure shielding program is malfunctioning after receiving the third-party assessment results. This allows them to further investigate other faults, narrowing the scope of their investigation, reducing the difficulty of troubleshooting, and improving the efficiency of troubleshooting.

[0061] In some embodiments of the present invention, the above-mentioned determination that the air conditioner does not store a low-pressure shielding program is followed by:

[0062] The low-pressure shielding procedure is retrieved and written from the blockchain so that the air conditioner executes the low-pressure shielding procedure the next time it starts up. The air conditioner is a node on the blockchain.

[0063] Specifically, if it's known that the air conditioner doesn't have a stored low-pressure shielding program, the air conditioner can be added to a blockchain as a node, and then retrieve the low-pressure shielding program from the blockchain. This setup allows the air conditioner to re-store the low-pressure shielding program so that it can be executed upon the next startup. This configuration not only ensures the normal operation of the air conditioner but also guarantees the authenticity and security of the low-pressure shielding program by using the blockchain, reducing the probability of air conditioner errors.

[0064] Regarding the air conditioner being a node on the blockchain, it should be noted that the blockchain in this embodiment is preferably a blockchain system. This blockchain generally includes multiple air conditioners as nodes, and the air conditioners utilize encryption technology to connect to the network for data transmission. In other words, the air conditioner uses encryption technology to transmit data with the blockchain via the network. This connection method can at least be used for uploading or downloading low-pressure shielding programs.

[0065] Furthermore, all air conditioners that support low-pressure shielding procedures can serve as nodes on the blockchain. This means that already sold air conditioners can also act as nodes, connecting with other nodes on the network. This setup allows already sold air conditioners to be upgraded by connecting to the blockchain, thereby continuously expanding their functionality and providing users with more and better services.

[0066] like Figure 3 As shown, in some embodiments of the present invention, the above-described process of obtaining and writing the low-voltage shielding procedure from the blockchain includes, prior to:

[0067] Step S41: Send a low-pressure shielding program acquisition request to the blockchain so that the blockchain responds to receiving the low-pressure shielding program acquisition request, verifies the air conditioner, and if the verification is successful, allows the air conditioner to acquire and write the low-pressure shielding program from the blockchain.

[0068] Specifically, the method for verifying the air conditioner is as follows: verify whether the air conditioner is a consensus node on the blockchain. If the verification is successful, the air conditioner is allowed to download the low-pressure shielding program. Further, the blockchain uses a consensus mechanism to determine whether the air conditioner sending the low-pressure shielding program request is a consensus node. If so, the air conditioner is allowed to obtain and write the low-pressure shielding program from the blockchain. This embodiment sets up a verification step before the air conditioner obtains the low-pressure shielding program to prevent other air conditioners from obtaining it.

[0069] In some embodiments of the present invention, the above-described process of obtaining and writing the low-voltage shielding program from the blockchain includes:

[0070] Step S42: In response to obtaining the low-voltage shielding procedure from the blockchain, match it with the low-voltage shielding procedure;

[0071] Step S43: When a match is successful, write the low-voltage shielding program.

[0072] Specifically, regarding step S42, it should be noted that the air conditioner needs to match its corresponding functional modules with the low-pressure shielding program. In other words, the air conditioner needs to have a corresponding functional module that controls the compressor's startup or normal operation to match the low-pressure shielding program. After successful matching, the low-pressure shielding program is written. When the compressor stops due to low temperature or operates abnormally, the low-pressure shielding program is executed to control the corresponding functional modules, ensuring the compressor starts or operates normally.

[0073] The setting method in this embodiment matches the low-pressure shielding program with the air conditioner, and then writes the low-pressure shielding program when the match is successful, thereby avoiding the air conditioner's own program crashing due to the installation of a low-pressure shielding program that is incompatible with itself.

[0074] In some embodiments of the present invention, the above-described air conditioner control method further includes:

[0075] Step S44: If a match fails, upload the matching result and air conditioner information to the blockchain.

[0076] The setting method in this embodiment feeds back the matching result and relevant information of the air conditioner to the blockchain system after a matching failure, so as to facilitate timely modification of the low-pressure shielding program.

[0077] like Figure 4 and Figure 5 As shown, this embodiment also provides a machine-readable storage medium and an air conditioner. Figure 4 This is a schematic block diagram of a machine-readable storage medium 40 according to an embodiment of the present invention.
