Detailed ways

Embodiments of the present disclosure are described in detail below, examples of which are illustrated in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present disclosure and should not be construed as limiting the present disclosure.

The remote debugging method of the air conditioning unit, the remote debugging device of the air conditioning unit, the air conditioning unit and the computer-readable storage medium proposed by the embodiments of the present disclosure are described below with reference to the accompanying drawings.

Fig. 1 is a flowchart of a remote debugging method for an air conditioning unit according to an embodiment of the present disclosure.

In an embodiment of the present disclosure, the air conditioner unit may include at least one outdoor unit and a plurality of indoor units connected to each outdoor unit, and a networking module corresponding to the outdoor unit. The networking module is used to obtain After the acquired data is cached, calculated, screened and other related processes are sent to the cloud server, so that the cloud server can remotely debug the air conditioning unit according to the uploaded data.

As shown in Figure 1, the remote debugging method of the air conditioning unit in the embodiment of the present disclosure may include the following steps:

S1. Determine the detection stages in the trial operation process of the air-conditioning unit, wherein the trial operation process of the air-conditioning unit includes multiple detection stages, and a corresponding data acquisition rule is set for each detection stage.

According to an embodiment of the present disclosure, a corresponding operation flag is set at each detection stage, wherein determining the detection stage during the trial operation of the air-conditioning unit includes: obtaining the operation flag during the trial operation of the air-conditioning unit; The flag bits determine the corresponding detection phase. It should be noted that the running flag bits are preset, and different running flag bits correspond to different detection stages.

Specifically, before the cloud server remotely debugs the air-conditioning unit, it first needs to conduct a test run on the air-conditioning unit to find out the problems of the air-conditioning unit, and the cloud server issues corresponding debugging instructions for debugging the problems found during the trial run. During the trial operation of the air conditioning unit, it includes multiple operation stages, such as the cold start stage, the stable operation stage, and the exit operation stage. Under different operating conditions, the operating parameters of the air conditioning unit are also quite different. In order to detect different operating states of the air-conditioning unit more accurately, multiple detection stages can be set correspondingly. In order to accurately detect the current detection stage of the air conditioner trial operation, the detection stage entered by the air conditioner unit trial operation can be obtained by detecting the operation flag.

For example, the trial operation process of the air conditioning unit can be divided into the following detection stages: preparation detection stage, first detection stage, second detection stage, third detection stage and end detection. As shown in Figure 2, the ordinate in the figure is the characteristic parameters of the air conditioning unit trial operation stage, the characterization parameters include but not limited to compressor frequency, exhaust temperature, or other unit operating parameters combined with each other, the abscissa in the figure is the running time of the air conditioning unit, and Step0, Step1, Step2, Step3, and Step4 on the abscissa are running flags, which are used to indicate that the trial operation of the air conditioning unit has entered different detection stages. Wherein, the operation flag Step0 indicates that it enters the stage of preparation for detection, and at this time, the air conditioning unit receives a remote debugging command and starts trial operation. The running flag Step1 indicates that it has entered the first detection stage. At this time, the air-conditioning unit is in the self-inspection state before operation. In this detection stage, it is detected whether the components of the air-conditioning unit can work normally. The data obtained in this detection stage can be used to detect whether the refrigerant system valve body components Whether it can be opened normally, whether there is leakage in the valve body and connecting parts, etc. The operation flag Step2 indicates that the second detection stage is entered. At this time, the start-up of the air-conditioning unit has been completed and entered a relatively stable operation state. In this detection stage, the stability of the operation of the air-conditioning unit begins to be detected. The data obtained in this detection stage can be whether the refrigerant charge is Normal, whether there is abnormal noise in the operation of the refrigeration system and compressor, whether the operating parameters of each point inspection are within the allowable range, etc. The running flag Step3 indicates that the third detection stage is entered. At this time, the air-conditioning unit performs refrigerant recovery or frequency reduction operation before the detection is completed. status etc. The operation flag Step4 indicates that the detection is completed, and the trial operation process of the air conditioning unit is completed.

It should be noted that the sequence of the above detection process is not limited to Step0→Step1→Step2→Step3→Step4, and the specific detection sequence can be designed differently according to different manufacturers and different detection modes.

Specifically, during the trial operation, the operating states of the air conditioning units in different detection stages are different. After entering each detection stage, the operating data of the air-conditioning unit in the detection stage can be obtained according to certain rules, so that the data obtained in each detection stage can represent the average level of the air-conditioning unit’s operation in the detection stage, and reflect the air-conditioning unit’s performance in the detection stage. The operating status of the stage. For example, the data acquisition rule in the second detection stage can be to obtain operation data after a period of stable operation (such as 5-10 minutes) in the second detection stage, or to judge according to the operation status parameters (for example, the operation status parameters tend to be stable), Or acquire data when the fluctuation of the exhaust temperature of the outdoor unit is less than 5°C. Therefore, each detection stage collects data according to corresponding data acquisition rules, which can reduce the collection of invalid data.

S2. Obtain the key point data of each detection stage according to the data acquisition rules corresponding to the detection stage.

Specifically, the key point data of each detection stage should be able to reflect the operating status of the air conditioning unit during the detection stage, so that the cloud server can evaluate the operating status of the air conditioning unit based on the key data points. The key point data can be the full operation data of the indoor and outdoor units in each detection stage, or the key operation data of the air-conditioning units in each detection stage after screening. The key point data can be one or more groups of air-conditioning unit operating data in the detection stage, which can be determined according to the cloud server's demand for data volume and the computing power and cache capacity of the gateway router. For example, when the current detection phase is in Step 2, the amount of refrigerant charged and the parameters characterizing the system operation stability are obtained; for another example, when the current detection phase is in Step 3, the amount of refrigerant recovery and the operating frequency of the air conditioning unit are obtained.

S3, at the end of the trial run process of the air conditioner unit, determine the test run result of the air conditioner unit, and upload data according to the test run result, so that the cloud server can remotely debug the air conditioner unit according to the uploaded data of the air conditioner unit.

Specifically, after each detection stage is completed or when a certain detection stage cannot be carried out, it is determined that the trial operation ends. Among them, in the trial operation process, all the detection stages are completed, and the trial operation result can be considered as normal completion; during the trial operation process of the air-conditioning unit, if there is a situation that cannot be carried out in a certain detection stage, the trial operation result can be determined as abnormal. After determining the test run results, the networking module can upload the collected key point data and test run results to the cloud server, so that the cloud server can issue corresponding remote debugging instructions according to the uploaded data to remotely debug the air conditioning unit.

The process of uploading data according to the test run results will be described in detail below in conjunction with specific embodiments.

According to an embodiment of the present disclosure, uploading data according to the test run results includes: when the test run process of the air conditioning unit is determined to end normally according to the test run results, if the acquisition of key point data satisfies the corresponding data acquisition rules, uploading the test run The running completion flag, test run diagnostic results and key point data are uploaded. Among them, the data acquisition rule of key point data is that the quantity of key point data must reach a certain value.

Further, according to an embodiment of the present disclosure, uploading data according to the test run results also includes: when the acquisition of key point data does not meet the corresponding data acquisition rules, the test run completion flag, test run diagnosis results and incomplete The key point data acquisition flag is uploaded.

Specifically, during the trial run, the self-contained program of the air conditioning unit can diagnose problems that occur during the trial run, such as the lack of refrigerant in the refrigerant pipe, etc., and generate test run diagnostic results. During the test run detection process of the air conditioner unit, when the run flag in the test run detection phase is the end run flag, or when a test run diagnosis result is generated, the test run of the air conditioner unit ends normally. The trial run of the air-conditioning unit ends normally, and the number of key point data obtained by the networking module meets the quantity specified in the data acquisition rules, and the trial run completion sign, test run diagnosis results and key point data are uploaded to the cloud server.

The trial run of the air-conditioning unit ends normally, but the quantity of key point data acquired does not meet the quantity specified in the data acquisition rules, and the mark of trial run completion, test run diagnosis results and network module incomplete key point data acquisition marks are uploaded. Among them, the field marked with the incomplete key point data acquisition can be empty.

According to an embodiment of the present disclosure, uploading data according to the test run results includes: when it is determined according to the test run results that the test run process of the air conditioner unit ends abnormally, if it is determined that the air conditioner unit has failed, uploading the fault code, test run unfinished The identification and the key point data of the cycle before the fault occurs are uploaded. Among them, the operation data of the period before the failure occurs is the full operation data of the internal and external units of the air conditioning unit, which can be determined by referring to the computing power of the gateway router, and corresponding trade-offs can be made.

Specifically, at a certain point during the trial operation of the air conditioning unit, a failure of the air conditioning unit itself was triggered, such as the exhaust temperature exceeded 100°C, etc., the air conditioning unit immediately stopped the trial operation, and the trial operation of the air conditioning unit ended abnormally. When a fault occurs, the air-conditioning unit generates a fault code according to the fault type, and sends out a fault signal of the air-conditioning unit and a sign that the trial operation is not completed. The networking module uploads the fault code of the air-conditioning unit, the unfinished trial run and the key point data of the cycle before the fault occurs to the cloud server.

In another embodiment of the present disclosure, the trial run incomplete flag may be generated when the gateway router judges that the trial run of the air conditioner unit is not completed according to the fault signal sent by the air conditioner unit, or may be determined by the air conditioner unit itself. According to an embodiment of the present disclosure, uploading data according to the test run result further includes: uploading an unfinished mark of the test run when it is determined that the air conditioner unit has not failed.

Specifically, during the test run, the commissioning personnel stopped the test run of the air conditioner unit due to an unexpected situation, and the air conditioner unit turned into normal operation or standby state, and the test run of the air conditioner unit ended abnormally, but the air conditioner unit did not malfunction. At this time, the networking module only uploads the test run incomplete flag to the cloud server to indicate that the air conditioner unit has not completed the test run, and the air conditioner unit needs to be re-tested in the later debugging process.

As a specific example, as shown in Figure 3, the data during the trial operation of the air conditioning unit is uploaded to the cloud service The controller may include the following steps.

S301. Determine the detection stage in the trial operation process of the air conditioning unit.

S302. Acquire the key point data of each detection stage according to the data acquisition rule corresponding to the detection stage.

S303, judging whether the trial run of the air conditioner unit is completed normally. If yes, execute step S304; if no, execute step S307.

S304, judging whether the acquisition of key point data satisfies a corresponding data acquisition rule. If yes, execute step S305; if no, execute step S306.

S305. Upload the test run completion flag, test run diagnosis results and key point data to the cloud server.

S306. Upload the sign of completion of the test run, the diagnosis result of the test run, and the sign of unfinished key point data acquisition to the cloud server.

S307, judging whether the air-conditioning unit fails. If yes, execute step S308; if no, execute step S309.

S308, uploading the fault code, the unfinished trial run flag, and the key point data of the cycle before the fault occurs to the cloud server.

S309. Upload the unfinished trial run flag to the cloud server.

To sum up, according to the remote debugging method of the air-conditioning unit in the embodiment of the present disclosure, by collecting the key point data of the air-conditioning unit in different detection stages, the overall process of the air-conditioning unit’s trial operation can be effectively monitored, and invalid data can be reduced. Channel and memory usage.

With the popularization of intelligence, existing air-conditioning units have gradually entered the stage of networked intelligent control. For the convenience of data communication and the standardization of production, each outdoor unit is usually equipped with a networking module to obtain the operating data of the outdoor unit and upload the operating data of the outdoor unit to the cloud server in real time. Among them, the networking module can be a 4G (The 4th Generation Mobile Communication Technology, fourth-generation mobile communication technology) communication module, a 5G (The 5th Generation Mobile Communication Technology, fifth-generation mobile communication technology) communication module, or a wifi (wireless network Communication technology) The communication module, the networking module uploads the operation data of the air conditioning unit to the cloud server through the mobile network or wireless network.

In some embodiments of the present disclosure, the air conditioning unit includes a plurality of outdoor units and a networking module corresponding to each outdoor unit, and the air conditioning unit connects the plurality of outdoor units in parallel to form a system, and communicates based on the principle of bus communication. In the communication process, in order to facilitate the control of the indoor and outdoor units of the air conditioning unit, multiple outdoor units are divided into master outdoor units and slave outdoor units. Each outdoor unit is connected to at least one indoor unit. The master outdoor unit receives the control When ordering, the control command is distributed to the corresponding slave outdoor unit to control the running state of the corresponding indoor unit. During the data upload process, each slave outdoor unit collects the operating data of the corresponding indoor unit, and sends the collected operating data to the main outdoor unit, and then Afterwards, the main outdoor unit uploads the operating data to the cloud server. Since each outdoor unit is equipped with a networking module, the slave outdoor unit uploads the operating data to the cloud server while sending the operating data to the main outdoor unit. It can be seen that in the process of data upload, the data from the outdoor unit is repeatedly uploaded, and the repeated upload of data from the outdoor unit causes data redundancy to occupy bandwidth, wastes data traffic, and increases network communication traffic. Expenses. Therefore, it is necessary to reduce data redundancy and traffic waste generated during the data upload process, and save expenses.

In order to reduce upload data redundancy and traffic waste, this disclosure proposes a data upload method for air-conditioning units. When uploading data of air-conditioning units, the corresponding data upload mechanism is determined according to the type of outdoor unit to upload data, which can reduce network module uploads. The data redundancy generated by the data and the traffic used, thereby avoiding the waste of network resources and saving the cost of network communication. The data uploading method of the air conditioning unit of the present disclosure will be described in detail below.

Fig. 6 is a flowchart of a data uploading method of an air conditioning unit according to an embodiment of the present disclosure.

As shown in FIG. 6, the data upload method of the air conditioning unit according to the embodiment of the present disclosure may include the following steps:

S31. Determine the type of the outdoor unit, where the type of the outdoor unit includes a master outdoor unit and a slave outdoor unit. In an embodiment of the present disclosure, there may be multiple slave outdoor units, and each outdoor unit may be connected to at least one indoor unit.

According to an embodiment of the present disclosure, determining the type of the outdoor unit includes: acquiring parameter information of the outdoor unit; and determining the type of the outdoor unit according to the parameter information of the outdoor unit. Wherein, the parameter information of the outdoor unit includes the address code of the outdoor unit, and the type of the outdoor unit can be determined according to the address code of the outdoor unit.

Specifically, when the air conditioner unit is installed, the installer can set the master-slave unit for the outdoor unit according to certain rules, and divide the outdoor unit into a master outdoor unit and multiple slave outdoor units. For example, the main outdoor unit is determined according to the number of indoor units connected to the outdoor unit, or according to the performance of the outdoor unit itself, for example, the outdoor unit with a large number of connected indoor The better outdoor unit is used as the master outdoor unit, and the other outdoor units except the master outdoor unit are used as slave outdoor units. Then mark the master outdoor unit and slave outdoor unit according to different address codes, for example, if the address code is set to 0#, it means the master outdoor unit, and if the address code is set to non-0#, it means the slave outdoor unit.

During the power-on operation of the air conditioning unit, the address code of each indoor unit is obtained through the networking module corresponding to each outdoor unit, and then it is judged whether the corresponding outdoor unit is the master outdoor unit or the slave outdoor unit according to the acquired address code. Wherein, when the address code of the outdoor unit is 0#, it can be determined that the outdoor unit is the master outdoor unit; when the address code of the outdoor unit is not 0#, it can be determined that the outdoor unit is the slave outdoor unit.

In some embodiments of the present disclosure, when the master and slave of the outdoor unit change, that is, the address code of the outdoor unit changes, the networking module can re-determine the type of the outdoor unit according to the changed address code information of the outdoor unit.

According to an embodiment of the present disclosure, before determining the type of the outdoor unit, the method further includes: setting each outdoor unit Establish a communication connection with the corresponding networking module.

That is to say, after the air conditioner unit is powered on, each outdoor unit can first establish a communication connection with the corresponding networking module according to the communication protocol. After the communication connection is established, the networking module can obtain the parameter information and operation of the corresponding outdoor unit. Parameter information, wherein the operating parameter information includes the operating parameters of the outdoor unit itself and the operating parameters of the correspondingly connected indoor unit.

S32. Determine the data upload mechanism according to the type of the outdoor unit, so as to upload the global data of the air conditioning unit through the networking module corresponding to the main outdoor unit, and/or upload the local data of the air conditioning unit through the networking module corresponding to the secondary outdoor unit .

According to an embodiment of the present disclosure, the global data of the air-conditioning unit includes the operating parameters and identification of each indoor unit in the air-conditioning unit, the operating parameters and identification of each outdoor unit, and the identification of each networked module. The air-conditioning unit The local data includes the identity of the outdoor unit and the identity of the networking module corresponding to the outdoor unit. Among them, the operating parameters of the outdoor unit may include: compressor operating frequency, compressor target frequency, outdoor unit defrosting status, outdoor unit current and voltage, outdoor ambient temperature, condenser temperature, compressor exhaust temperature, and the identity of the outdoor unit , outdoor unit controller parameters, outdoor unit fault code, outdoor wind speed status, etc. The identity of the outdoor unit can include the SN (Serial Number, product serial number) code of the outdoor unit. The operating parameters of the indoor unit may include: the inlet and outlet temperature of the indoor heat exchanger, the flow rate of the refrigerant, the condition of the indoor heat exchanger being blocked, power, voltage, current, etc., and the identity of the indoor unit may include the SN code and/or Internal machine address. The identity mark of the networking module may include SN code and/or ICCID (Integrate Circuit Card Identity, integrated circuit card identification code).

Specifically, after the type of the outdoor unit is determined through the above step S31, the data upload mechanism is determined according to the type of the outdoor unit. Wherein, when the type of the outdoor unit is the main outdoor unit, its correspondingly connected networking module will obtain the data of each indoor unit. The operating parameters of each indoor unit, each outdoor unit and each networking module are uploaded to the cloud server; when the type of outdoor unit is slave outdoor unit, its corresponding connected networking module The identity of the corresponding network module and the identity are uploaded to the cloud server.

For example, when using an air-conditioning unit, the user can send a control command according to his own needs, so that the outdoor unit corresponding to the indoor unit that needs cooling or heating can work to meet the indoor cooling or heating demand. There are many ways to send control commands, you can send control commands through the wire controller, you can also send control commands through the terminal equipment, or send control commands through the host computer (such as office buildings or shopping malls, generally through the host computer in the monitoring room) Control instruction).

During the operation of the air conditioner unit, when the current outdoor unit is determined to be the master outdoor unit according to the address code, since the master outdoor unit receives the parameter information sent by other slave outdoor units, that is, the master outdoor unit contains all the parameter information of the entire air conditioner unit, At this time, the networking module will upload all the data in the main outdoor unit to the cloud server; When the current outdoor unit is set as the slave outdoor unit, in order to avoid duplication of data upload and waste of traffic, the networking module corresponding to the slave outdoor unit only needs its own SN code, ICCID and the SN code of the slave outdoor unit to upload to the cloud server.

That is to say, the networking module corresponding to the master outdoor unit is responsible for uploading its own identity and the operating parameters of the entire unit, and the networking module corresponding to the slave outdoor unit is responsible for uploading its own identity and the identity of the slave outdoor unit, thus ensuring global While uploading data, avoid repeated data uploads and traffic waste.

That is to say, when the networking module connected to the main outdoor unit implements the global data upload mechanism, the upload period can be a preset period, or a period set remotely by the cloud server, for example, the global data upload period can be set 1min-60min. When the networking module connected with the slave outdoor unit will implement the local data upload mechanism, the cycle of local data upload can be the same as the cycle of global data upload, or longer than the cycle of global data upload, for example, the cycle of local data upload can be set as 1h-24h. The reason why the global data upload cycle is shorter than the local data upload cycle is that firstly, the integrity and consistency of the global data uploaded to the cloud server are guaranteed, and secondly, the local data upload cycle can be longer because the global data already includes local data. Some, this can reduce the frequency of partial data uploads, thereby reducing the usage of data traffic.

Further, in some embodiments of the present disclosure, uploading the local data of the air conditioning unit from the networking module corresponding to the outdoor unit includes: receiving a periodic query instruction from the cloud server; and uploading the local data of the air conditioning unit according to the periodic query instruction upload.

In other words, when the current outdoor unit is a slave outdoor unit, the networking module corresponding to the slave outdoor unit may upload its own identity and the identity of the corresponding outdoor unit to the cloud server according to the set period, or it may be When receiving the periodic query instruction sent by the cloud server, upload its own identity and the identity of the corresponding outdoor unit to the cloud server according to the query instruction. On the contrary, when the query instruction is not received, the networking module does not upload the corresponding parameters, so that the data traffic consumed by the networking module uploading data can be reduced.

It should be noted that even if the master-slave outdoor unit of the air-conditioning unit changes, the corresponding networking module can also obtain the SN code of the outdoor unit, and the data upload mechanism is determined according to the SN code, which is highly versatile and applicable to the operation of any air-conditioning unit Scenes.

To sum up, according to the data upload method of the air conditioning unit in the embodiment of the present disclosure, after the type of the outdoor unit is determined, the data upload mechanism is determined according to the type of the outdoor unit, and the data uploading mechanism of the corresponding outdoor unit is determined through the networking module connected to the outdoor unit. The upload mechanism uploads the data of the air conditioning unit. Therefore, when uploading the data of the air conditioning unit, the method determines the corresponding data upload mechanism to upload data according to the type of the outdoor unit, which can reduce the data redundancy and the traffic used when the networking module uploads data, thereby avoiding the waste of network resources , Save the cost of network communication.
