Based on the scene of the air conditioner fault detection method, the embodiment of the air conditioner fault detection method is provided.

As shown in fig. 2, which is a schematic flow chart of an embodiment of an air conditioner fault detection method in the embodiment of the present application, the air conditioner fault detection method includes steps S201 to S203:

s201, responding to a fault reporting signal of the air conditioner, and acquiring air conditioner operation data within a preset time length corresponding to the fault reporting signal.

The fault error signal, that is, fault error information generated when the air conditioner has a fault, may be, for example, a fault code, a fault type, and the like, and it can be understood that the fault code is a preset fault code corresponding to different fault types.

The preset time is used for limiting the quantity of the air conditioner operation data for analyzing the fault reason, namely, if the preset time is three days, the air conditioner operation data in the preset time is the air conditioner operation data collected in the previous three days for responding the time corresponding to the fault error reporting signal of the air conditioner as a time end point. It is understood that the preset time period may be set according to actual requirements, such as a week, a month, and the like, and the specific application is not limited thereto.

The air conditioner operation data, that is, the air conditioner operation data corresponding to the fault type corresponding to the fault error signal, for example, if the fault type corresponding to the fault error signal may be a temperature detection fault, obtaining temperature detection data within a preset time period, that is, the temperature detection data is an air conditioner operation parameter; it can be understood that the air conditioner operation parameters may be different data corresponding to different fault types, for example, the air conditioner operation parameters may also be compressor operation parameters corresponding to a compressor fault (fault type), fan operation parameters corresponding to a fan fault, and the like.

It can be understood that the air conditioner operation data carries time information, that is, the time information of the operation data is acquired and determined when the air conditioner operation data is acquired.

Specifically, in the embodiment of the present application, the air conditioner fault detection method is applied to an air conditioner fault detection device, where the air conditioner fault detection device is specifically a background management device of an air conditioner, such as a computer, a mobile phone, and the like, and is configured to receive a fault error signal communicated with the air conditioner fault detection device and receive air conditioner operation data uploaded by the air conditioner.

Specifically, air conditioner fault detection equipment responds the fault error signal of air conditioner after receiving the fault error signal that the air conditioner sent, acquires the air conditioner operating data in the time length of predetermineeing that fault error signal corresponds, and is concrete, according to fault code (fault error signal) confirms the fault type, acquires the air conditioner operating data in the time length of predetermineeing that fault error signal corresponds, specifically, acquires air conditioner operating data's implementation mode this application does not do specific restriction, for example:

in one embodiment of the present application, after receiving a fault error signal sent by an air conditioner, an air conditioner fault detection device responds to the fault error signal of the air conditioner, determines a fault type of the fault code (fault error signal), and then searches a database according to the fault type to obtain air conditioner operation data corresponding to the fault type of the air conditioner (the air conditioner sending the fault error signal) within a preset time period.

In some other embodiments of the present application, after receiving a fault error signal sent by an air conditioner, an air conditioner fault detection device determines a fault type according to a fault code (fault error signal) in response to the fault error signal of the air conditioner, determines a data type of air conditioner operation data corresponding to the fault type, and then sends an air conditioner data acquisition request carrying the data type to a target air conditioner corresponding to the air conditioner identifier, where the data type is a data type of air conditioner operation data to be acquired; and receiving air conditioner operation data within a preset time length fed back by the target air conditioner.

S202, determining air conditioner fault time corresponding to the air conditioner fault according to the air conditioner operation data and the operation data threshold corresponding to the fault reporting signal.

The operation data threshold, that is, the preset operation data threshold of the fault type corresponding to the air conditioner (the air conditioner with the fault error signal sent, that is, the air conditioner with the fault) is used to determine whether the operation data of the air conditioner is abnormal, and corresponding experimental verification and acquisition can be performed according to different air conditioners and fault types of the air conditioner.

The failure time, that is, the time when the air conditioner fails, may be a time point or a time period. It can be understood that, when the air conditioner is out of order, generating a fault code, that is, generating a fault error signal, is an accumulation process of an air conditioner operation data abnormality, and may generate the fault error signal only when the accumulation reaches a certain value, and further, a time error may exist in the sending time and the response time of the fault error signal, so that the air conditioner operation data abnormality needs to be analyzed to determine the actual time of the air conditioner fault.

Specifically, after the air conditioner fault detection device detects and responds to a fault error reporting signal of an air conditioner and acquires air conditioner operation data within a preset time period corresponding to the fault error reporting signal, according to the air conditioner operation data and an operation data threshold corresponding to the fault error reporting signal, air conditioner fault time corresponding to the fault error reporting of the air conditioner is determined, specifically, for example:

in some embodiments of the present application, the air conditioner fault detection device compares the air conditioner operation data with the operation data threshold respectively to obtain abnormal data in the air conditioner operation data, and determines air conditioner fault time according to time information corresponding to the abnormal data, for example, selects one of the time information corresponding to the abnormal data as air conditioner fault time, or generates a minimum time interval including all the time information according to the time information corresponding to the abnormal data, and uses the minimum time interval as air conditioner fault time.

In other embodiments of the present application, the air conditioner fault detection device analyzes and searches the air conditioner operation data through a preset abnormal value algorithm or model to obtain abnormal data in the air conditioner operation data, and determines the air conditioner fault time according to time information corresponding to the abnormal data, for example, one of the time information corresponding to the abnormal data is selected as the air conditioner fault time, or a minimum time interval including all the time information is generated according to the time information corresponding to the abnormal data and is used as the air conditioner fault time.

S203, determining a fault reason corresponding to the fault error signal according to the environment parameter corresponding to the air conditioner fault time.

The environmental parameter, which affects the fault corresponding to the fault time of the air conditioner, may be, for example, an ambient temperature, an ambient humidity, an air quality, or the like; it can be understood that the corresponding relationship between the environmental parameters that affect the fault may be preset, that is, the environmental parameters and the fault type are associated, that is, the environmental parameters corresponding to the fault type at the time of the fault of the air conditioner may be obtained after the time of the fault of the air conditioner is determined, and it can be understood that the association between the environmental parameters and the fault type may be changed and edited.

Specifically, the air conditioner fault detection device determines a fault cause corresponding to the fault error signal according to an environmental parameter corresponding to the air conditioner fault time, exemplarily, compares the environmental parameter corresponding to the fault time with a parameter threshold of the environmental parameter (for determining whether the environmental parameter will cause the air conditioner fault corresponding to the fault type), and if the environmental parameter is greater than the parameter threshold, it is indicated that the environmental parameter will cause the air conditioner fault corresponding to the fault type, that is, the environmental parameter greater than the parameter threshold is a fault cause.

Specifically, in this application embodiment, air conditioner trouble detection equipment is according to air conditioner operational data with the operational data threshold value that fault report signal corresponds confirms behind the air conditioner fault time that the air conditioner report error corresponds, acquire the environmental parameter that air conditioner fault time corresponds, it is right the environmental parameter that air conditioner fault time corresponds carries out data analysis, and then confirms the fault reason that fault report error signal corresponds.

It can be understood that the environmental parameters corresponding to the fault types may include a plurality of environmental parameters, that is, in one embodiment of the present application, after determining the fault cause corresponding to the fault error-reporting signal according to the environmental parameters corresponding to the fault time of the air conditioner, the air conditioner fault detection device accumulates the environmental parameters corresponding to the fault cause, and if the statistical number of the environmental parameters corresponding to the fault cause in a preset time period is less than a preset statistical number threshold, feeds back an association update prompt of the environmental parameters and the fault types, which is used to prompt a user to optimize an association relationship between the environmental parameters and the fault types, or the air conditioner fault detection device automatically deletes the association relationship between the environmental parameters and the fault types, where the statistical number is less than the association relationship between the environmental parameters and the fault types corresponding to the preset statistical number threshold; illustratively, the fault type a and the environmental parameter a, the environmental parameter B and the environmental parameter C have an association relationship respectively, and then the fault reason corresponding to the fault error-reporting signal is determined according to the environmental parameter corresponding to the air conditioner fault time, including analyzing the environmental parameter a, the environmental parameter B and the environmental parameter C corresponding to the air conditioner fault time, determining that the fault reason is related to the environmental parameter a, counting the environmental parameter a for a number of times, and if the counted number of times of the environmental parameter C within a preset time period is less than 1 (a counted number threshold), deleting the association relationship between the environmental parameter C and the fault type a, that is, when the fault reason corresponding to the fault type a is analyzed next time, analyzing the data based on the environmental parameter a and the environmental parameter B having an association relationship with the fault type a, so as to improve the data analysis efficiency.

Further, on the basis of the above embodiments, referring to fig. 3, fig. 3 is a schematic flow chart of one embodiment of determining an air conditioner fault time in the air conditioner fault detection method provided in the embodiment of the present application, and the method includes steps S301 to S303:

s301, determining abnormal data in the air conditioner operation data according to the data distribution information of the air conditioner operation data.

The data distribution information may be a normal distribution map, a box plot, or the like, and is used for analyzing abnormal data in the air conditioner operation data, and it is understood that the data distribution information may be determined as abnormal data by determining outlier data in the normal distribution map or the box plot.

Specifically, in the embodiment of the present application, the data distribution information is a box diagram, and the air conditioner fault detection device performs calculation and analysis on the air conditioner operation data according to a preset box diagram algorithm after acquiring the air conditioner operation data within a preset time period corresponding to the fault error signal, so as to obtain the box diagram of the air conditioner operation data and acquire an outlier in the box diagram, where the outlier is abnormal data in the air conditioner operation data.

S302, determining target abnormal data in the abnormal data according to the difference relation between the abnormal data and the operation data threshold corresponding to the fault error signal.

The operation data threshold, that is, the threshold used for determining whether abnormal data is actually abnormal, may be understood that the abnormal data is abnormal data in the data distribution information, and it is further determined whether the abnormal data is abnormal data that actually affects an air conditioner fault through the abnormal data threshold. That is, it can be understood that the target operation data is abnormal data that actually affects the air conditioner malfunction.

The difference relationship may be a magnitude relationship, a relationship whether the phases are the same, and the like, and the difference relationship is different thresholds according to different air conditioner operation parameters, and the specific application is not limited specifically.

Specifically, in the embodiment of the present application, determining target abnormal data in the abnormal data according to a difference relationship between the abnormal data and an operation data threshold corresponding to the fault error signal specifically includes:

(1) Comparing the abnormal data with an operation data threshold corresponding to the fault error signal;

(2) And if any abnormal data is larger than the operating data threshold value, determining the abnormal data larger than the operating data threshold value as target abnormal data.

That is, after acquiring abnormal data, the air conditioner fault detection device compares the abnormal data with an operation data threshold corresponding to the abnormal data, and if abnormal data larger than the operation data threshold exists, determines that the abnormal data larger than the operation data threshold is target abnormal data.

It can be understood that, in some other embodiments of the present application, if there is target abnormal data, determining an air conditioner fault time corresponding to an error report of the air conditioner according to the target abnormal data; and determining a fault reason corresponding to the fault error reporting signal according to the environment parameter corresponding to the air conditioner fault time.

In other embodiments of the present application, if there is no target abnormal data, the air conditioner operation data is divided to obtain operation data corresponding to a plurality of different time periods; and calculating the operation data corresponding to each time period according to a preset box plot algorithm to obtain a box plot of the operation data corresponding to each time period, and determining target abnormal data in the air conditioner operation data according to the abnormal data in the box plot of the operation data corresponding to each time period.

And S303, determining the air conditioner fault time corresponding to the air conditioner error report according to the time information corresponding to the target abnormal data.

The time information corresponding to the abnormal data, that is, the time information for acquiring the abnormal data, may be understood that the abnormal data is one of the operation data in the air conditioner operation data, that is, the time information for acquiring the operation data, and it may be understood that the time information carries the number of the operation users, or the acquisition time of each data in the air conditioner operation data corresponds to each operation data for performing associated storage, and after it is determined that the target abnormal data is clear, the time information corresponding to the target abnormal data may be directly acquired.

Specifically, the air conditioner fault detection device determines, according to the time information corresponding to the target abnormal data, a specific implementation manner of the air conditioner fault time corresponding to the air conditioner error report, which is not specifically limited in the last year, for example, one of the time information corresponding to the abnormal data is selected as the air conditioner fault time, or a minimum time interval including all the time information is generated according to the time information corresponding to the abnormal data and is used as the air conditioner fault time.

Further, on the basis of the above embodiment, referring to fig. 4, fig. 4 is a schematic flow chart of one embodiment of determining abnormal data in the air conditioner fault detection method provided in the embodiment of the present application, including steps S401 to S404:

s401, calculating the air conditioner operation data according to a preset box line graph algorithm to generate a first box line graph.

The preset box line graph algorithm can be a preset box line graph algorithm model, and the first box line graph can be obtained by inputting the air conditioner operation data into the box line graph algorithm model.

The first box diagram is a box diagram calculated according to all air conditioner operation parameters within a preset time period.

Specifically, after responding to a fault error signal of an air conditioner and acquiring air conditioner operation data within a preset time period corresponding to the fault error signal, the air conditioner fault detection device inputs the air conditioner operation data within the preset time period into a preset box line diagram preset algorithm model to obtain a corresponding first box line diagram.

S402, if abnormal data are not obtained based on the first boxplot, dividing the air conditioner operation data according to time information corresponding to the air conditioner operation data to obtain first operation data corresponding to a first time period and second operation data corresponding to a second time period.

And the total duration corresponding to the first time period and the second time period is preset duration.

Specifically, the air conditioner fault detection device inputs air conditioner operation data within a preset time period into a preset box line graph algorithm model, after a corresponding first box line graph is obtained, an outlier in the first box line graph is not detected, that is, abnormal data is not detected, a bisection method is adopted to divide the air conditioner operation data within the preset time period, the air conditioner operation data is divided into first operation data corresponding to a first time period and second operation data corresponding to a second time period, and specifically, the air conditioner operation data is divided into the first operation data corresponding to the first time period and the second operation data corresponding to the second time period according to a time midpoint of time information corresponding to the air conditioner operation data included in the preset time period.

It is to be understood that, in some other embodiments of the present application, the air conditioner operation data may not be divided from a time midpoint corresponding to the time information corresponding to the preset time period, or the air conditioner operation data may be divided into first operation data corresponding to the first time period, second operation data corresponding to the second time period, and third operation data corresponding to the third time period, where the present application is not limited specifically.

S403, calculating the first operation data according to a preset boxplot algorithm to obtain a second boxplot, and calculating the second operation data according to a preset boxplot algorithm to obtain a third boxplot.
