The embodiment of the invention aims to utilize a big data platform to carry out centralized analysis on fault information which is reported by a plurality of users and related to an air conditioning system to obtain an optimization scheme so as to optimize the control process of the air conditioning system, improve the quality of the air conditioning system and improve the user experience.

Air conditioning systems include components such as a compressor, a condenser, a throttle device, and an evaporator, and the cause of a failure may be problematic from one or more of these components during operation of the air conditioner. And in order to realize the optimization of different components, selecting the fault grade corresponding to the different components for analysis and processing. For example: the air conditioner fault level comprises four levels, wherein the second fault level is caused by the compressor level, and when the compressor needs to be optimized, reported information of the second fault level corresponding to the compressor can be acquired for research. For an air conditioning system, a compressor is the most core component and is the component with the most faults, and the method provided by the invention is mainly used for monitoring the fault reporting rate related to the compressor and updating the compressor or the control algorithm of the compressor by synthesizing the fault reporting data.

Fig. 1 shows an updating method for an air conditioning system according to an embodiment, including:

and step S101, acquiring the reporting rate of the set fault level in the set time.

And step S102, when the report rate is greater than a first set value, acquiring equipment information corresponding to the set fault level and determining an updating strategy according to the equipment information. Wherein the device information includes: the model number and the temporary compressor frequency when the set fault level is reported.

In order to ensure that the acquired fault data can intensively reflect the problems of the air conditioning system, so as to improve the updating efficiency, effectively improve the quality of the air conditioning system and acquire the reporting rate of the set fault grade in the set time. The set time is a time period for the user to intensively apply the air conditioning system, for example, the set time is from May to September or from October to the next trimester, so that the number of samples can be ensured, and the air conditioners can be ensured to run in the same working mode.

In step S102, when the reporting rate is greater than a first set value, obtaining device information corresponding to the set fault level and determining an update policy according to the device information. Wherein the device information includes: the model number and the temporary compressor frequency when the set fault level is reported. The first set value is 30-70%. Optionally, the first set point is 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, or 70%. Determining the value of the first set value according to the number of the fault class, for example: when the fault grades are classified into three types, determining that the first set value is 70%; when the fault level has six categories, the fault reporting condition is dispersed compared with the fault level having three categories, and in order to determine the updating strategy in time, the first set value should be less than 70%, and optionally, the first set value is determined to be 30%, 35% or 40%.

The failure of the air conditioning system has many reasons, and in order to analyze the problems of the air conditioning system components in a centralized manner, the updating strategy is suitable for updating the air conditioning systems of a plurality of users, and the failure grade with the reporting rate larger than the first set value is selected for further analysis to determine the updating strategy. The first set value is determined according to a fault reporting rate obtained when the air conditioning system is tested under a standard working condition. As described above, in the actual application process, the outdoor environment changes continuously, and the indoor and outdoor temperatures are different from the standard working condition in most cases, so that the possibility of failure is high, and in order to determine the update strategy in time, avoid the air conditioning system from failing, reduce the user experience, the first set value is less than or equal to the failure reporting rate obtained when the air conditioning system is tested under the standard working condition.

At present, in order to meet the diversified demands of users, the types of air conditioning systems are many, and the input power or the output power of the air conditioning systems of different types may be different. When the input power or the output power is different, the reasons of the air conditioner fault are different, so that the equipment information corresponding to the set fault level is acquired to ensure the effectiveness of the updating strategy on the updating of the air conditioning system, and the classification analysis is conveniently carried out according to the model when the updating strategy is analyzed and determined. The method provided by the embodiment is mainly used for monitoring and updating the core component compressor, so that the analysis of the state of the compressor when the compressor fails is facilitated, and the acquired equipment information comprises the temporary working frequency when the fault is reported.

In this embodiment, the fault reporting conditions of the air conditioning systems of multiple users are acquired to intensively reflect the problems existing in the air conditioning systems of the multiple users, when the occurrence rate of a certain fault level is relatively prominent, it is determined that the probability of the fault occurring in the air conditioning systems of other users is relatively high, and then the reason causing the fault is determined by analyzing the equipment information of the air conditioning system acquiring the fault, so that developers can conveniently and uniformly upgrade the air conditioning systems, the quality of the air conditioning systems is improved, the air conditioning systems of more users are prevented from being faulty due to the same reason, and the user experience is improved.

In some optional embodiments, as shown in fig. 2, to further ensure that the acquired fault data can collectively reflect the problems existing in the air conditioning system, so as to improve the updating efficiency, ensure that the updating policy is suitable for updating the air conditioning systems of multiple users, and effectively improve the quality of the air conditioning system, step S201 is further included before step S101 to acquire the reported data of the fault of the air conditioning system in the set area. Wherein, reporting data comprises: fault level, location information, and equipment information.

Optionally, the location information may be determined according to a communication address of the air conditioning system. Optionally, the air conditioning system includes a positioning module, and the position information is determined by the positioning module. In some optional embodiments, the selected set area is one or more cities. In some optional embodiments, the selected set area is one or more urban areas of a city. In some optional embodiments, the selected set area is one or more adjacent cells. When the reported data of the faults of the air-conditioning system in the set area is obtained, the sample capacity needs to be ensured to intensively reflect the reporting condition of the faults. The reported data of the air conditioning system faults in the set area are obtained to ensure that the outdoor environment of the air conditioning system is kept in a relatively balanced state, and poor applicability of the updating strategy caused by large difference of the outdoor environment of the researched air conditioning system is avoided.

In the foregoing embodiments, the update policy is determined in various forms according to the device information. Fig. 3 illustrates an exemplary method for determining an update policy based on device information. The method comprises the following steps:

step S301, determining the percentage of the number of the air conditioning systems of each model in all the models.

Step S302, when the model with the percentage larger than the second set value exists, acquiring the temporary compressor frequency corresponding to the model.

Step S303, determining different updating strategies according to the temporary compressor frequency.

The air-conditioning systems are different in model, different in input power, output power or input power and output power, and different in corresponding updating strategy, so that the percentage of the air-conditioning systems of different models reporting the set fault level in all the air-conditioning systems reporting the set fault level is determined at the beginning of determining the updating strategy, and when the percentage is larger than the second set value, the air-conditioning systems of the model are taken as the updating object and the updating strategy is formulated. And when an updating strategy is formulated, acquiring the temporary working frequency of the air conditioning system of the type when the failure level is set, and determining different updating strategies according to the temporary compressor frequency. Wherein the second set value is 30-50%. Optionally, the first set value is 30%, 35%, 40%, 45% or 50%.

Specifically, the frequency of the compressor is adjustable, and the air conditioning system divides the output power into different frequency levels according to the output power. Different control algorithms are preset corresponding to different frequency grade systems. And when an updating strategy is formulated, determining the frequency grade of the temporary compressor frequency, and updating the control algorithm of the air conditioning system according to the ratio of the number of the air conditioning systems corresponding to different frequency grades. Optionally, the frequency grade corresponding to the model with the ratio greater than the set ratio is determined, and the control algorithm corresponding to the frequency grade is determined to be updated. Optionally, the frequency class corresponding to the model with the largest ratio is determined, and the control algorithm corresponding to the frequency class is determined to be updated.

As described below, according to an embodiment, an updating method for an air conditioning system needs to analyze a reporting rate of IPM protection failures, and further determine whether to make an updating policy and how to make the updating policy. In this embodiment, the first set point is 70% and the second set point is 35%.

Firstly, reported data of faults of a certain urban air conditioning system are obtained, wherein the reported data comprise reported data about IPM protection faults and other faults. In the reported data, the report rate of the IPM protection fault in 3 months in 2018 is obtained. The reporting rate is the percentage of the number of the air conditioning systems reporting the IPM protection fault in the number of all the air conditioning systems reporting the fault. When the report rate of the IPM protection fault is greater than the first set value, namely 70%, the fault is a high-occurrence fault, and an update strategy for the IPM protection fault needs to be determined.

After determining that an update strategy is to be determined for the IPM protection fault, a model corresponding to the IPM protection fault and a temporary compressor frequency at which the IPM protection fault is reported are obtained.

Further, determining the number of the air-conditioning systems of each type reporting the IPM protection faults, wherein the number of the IPM protection faults reported by the type A is 50, and the reported IPM protection faults account for 40%, determining the air-conditioning system of the type A as an updating object, and acquiring the frequency of the temporary compressor of each type A.

The frequency grades of the A type air conditioning system compressor frequency are divided into three grades of low, medium and high in the following table 1:

TABLE 1

Frequency class	Definition of	Compressor frequency value
			Is low in	G moment	0～29Hz
In	M moment	30～50Hz
			Height of	Moment of force D	Over 51Hz

As shown in table 2, the number and percentage of the air conditioning systems of type a with IPM protection fault reported by the IPM protection fault when the temporary compressor frequency is at different frequency levels are obtained by statistics:

TABLE 2

Frequency class	Definition of	Number of faulty air conditioning systems	Ratio of failure
				Is low in	G moment	3	6％
In	M moment	41	82％
				Height of	Moment of force D	6	12％

As shown in table 2, the number of the air conditioning systems of type a corresponding to the medium frequency class accounts for 82% of the number of all the type a, while the medium frequency class corresponds to M torque drive adjustment, and it is determined according to table 2 that the M torque drive adjustment needs to be updated, that is, the control algorithm of the air conditioning system corresponding to the medium frequency class is updated.

In some optional embodiments, the method for determining the update policy according to the device information as shown in fig. 4 includes:

step S401, determining the percentage of the number of the air conditioning systems of each model in all the models.

Step S402, when the model with the percentage larger than a second set value exists, acquiring the temporary compressor frequency corresponding to the model; otherwise, the temporary compressor frequency corresponding to the model with the largest percentage is acquired.

Step S403, determining different update strategies according to the temporary compressor frequency.

In step S402, when the percentage of the air conditioning system of each model is less than or equal to the second set value, the frequency of occurrence of the failure level is set to be even, and at this time, the model with the largest percentage is used as the update target. Further, the temporary compressor frequency corresponding to the model with the largest percentage is acquired and step S403 is performed.

In the foregoing embodiment, the compressor frequency is mainly used as a basis for fault analysis in the process of determining the update strategy, and in order to improve the accuracy of the update strategy in adjusting the air conditioning system, reduce the fault reporting rate, optimize the quality of the air conditioning system, and improve the user experience, in some optional embodiments, the operation parameters of various air conditioning systems are obtained when the update strategy is determined to be integrated.

Fig. 5 shows an updating method for an air conditioning system according to an embodiment, including:

step S501, obtaining the reporting rate of the set fault level in the set time.

Step S502, when the report rate is greater than a first set value, acquiring the equipment information corresponding to the set fault level and determining an updating strategy according to the equipment information. Wherein the device information includes: the model and the temporary operation parameters when the set fault level is reported; the temporary operating parameters comprise a first parameter and a second parameter; the first parameter is compressor frequency; the second parameter includes one or more of an indoor fan speed, an indoor ambient temperature, an outdoor ambient temperature, and a target set temperature.

In step S502, when the reporting rate is greater than a first set value, obtaining device information corresponding to the set fault level and determining an update policy according to the device information. Wherein the device information includes: the model and the temporary operation parameters when the set fault level is reported, wherein the temporary operation parameters comprise a first parameter and a second parameter. The optimization key element based on this application is the compressor, for the precision that improves the update strategy regulation air conditioning system that confirms, improves air conditioning system's optimization quality, and first parameter is the compressor frequency, the second parameter includes in indoor fan rotational speed, indoor ambient temperature, outdoor ambient temperature and the target set temperature one or more.

Wherein, the value range of the first set value is 30-70%. Optionally, the first set point is 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, or 70%. Determining the value of the first set value according to the number of the fault class, for example: when the fault grades are classified into three types, determining that the first set value is 70%; when the fault level has six categories, the fault reporting condition is dispersed compared with the fault level having three categories, and in order to determine the updating strategy in time, the first set value should be less than 70%, and optionally, the first set value is determined to be 30%, 35% or 40%. The failure of the air conditioning system has many reasons, and in order to analyze the problems of the air conditioning system components in a centralized manner, the updating strategy is suitable for updating the air conditioning systems of a plurality of users, and the failure grade with the reporting rate larger than the first set value is selected for further analysis to determine the updating strategy. The first set value is determined according to a fault reporting rate obtained when the air conditioning system is tested under a standard working condition. As described above, in the actual application process, the outdoor environment changes continuously, and the indoor and outdoor temperatures are different from the standard working condition in most cases, so that the possibility of failure is high, and in order to determine the update strategy in time, avoid the air conditioning system from failing, reduce the user experience, the first set value is less than or equal to the failure reporting rate obtained when the air conditioning system is tested under the standard working condition.

Firstly, based on the current situation that the types of the air conditioning systems are numerous, in order to ensure the effectiveness of the updating strategy for the air conditioning systems, the equipment information including the types corresponding to the set fault levels is acquired, and classification analysis is conveniently carried out according to the types when the updating strategy is analyzed and determined. Secondly, the method provided by this embodiment is mainly used for monitoring and updating the core component compressor, so that the analysis of the state of the compressor when the fault occurs is facilitated, and the obtained device information includes the temporary working frequency when the fault is reported. And finally, determining an updating strategy for integrating the operating parameters of various air-conditioning systems so as to improve the accuracy of the updating strategy in adjusting the air-conditioning systems, reduce the fault reporting rate, optimize the quality of the air-conditioning systems, and improve the user experience, wherein the acquired equipment information further comprises one or more of the rotating speed of an indoor fan, the indoor environment temperature, the outdoor environment temperature and the target set temperature.

In some optional embodiments, as shown in fig. 6, to further ensure that the acquired fault data can collectively reflect the problems existing in the air conditioning system, so as to improve the updating efficiency, ensure that the updating policy is suitable for updating the air conditioning systems of multiple users, and effectively improve the quality of the air conditioning system, step S601 is further included before step S501 to acquire the reported data of the fault of the air conditioning system in the set area. Wherein, reporting data comprises: fault level, location information, and equipment information.

In the foregoing embodiments, the update policy is determined in various forms according to the device information. Fig. 7 illustrates an exemplary method for determining an update policy based on device information. The method comprises the following steps:

and step S701, determining the percentage of the number of the air-conditioning systems of each model in all the models.

Step S702, when the model with the percentage larger than the second set value exists, acquiring the temporary operation parameter corresponding to the model.

And step S703, determining different updating strategies according to the temporary operation parameters.

The frequency of the compressor is adjustable, and the air conditioning system divides the output power into different frequency grades according to the size of the output power. Different control algorithms are preset corresponding to different frequency grade systems. In different embodiments, the difference in the second parameter affects the load on the compressor. In some embodiments, because the load of the compressor is too large due to the second parameter, the user cannot accurately determine the cause of the failure of the air conditioning system and report the failure, and at this time, the corresponding failure report data cannot directly reflect that the element of the air conditioning system has the failure.

In some embodiments, in order to improve the accuracy of adjusting the air conditioning system by the determined updating strategy and improve the optimization quality of the air conditioning system, the fault reporting data is analyzed by integrating various parameters to determine the updating strategy. Specifically, step S703 includes: determining a level of the first parameter; determining the ratio of the second parameter to the number of different levels of equipment within a set range; and updating the control algorithm of the air conditioning system according to the ratio.

In some optional embodiments, the second parameter is an indoor fan speed. The load of the compressor when the indoor fan of the air conditioning system operates at low speed or medium speed is higher than the load of the compressor when the indoor fan operates at high speed, so the probability of reporting the set fault level under the condition of low rotating speed of the indoor fan of the air conditioning system is higher, and the indoor fan of the air conditioning system in the fault reporting data is not suitable to be used as a basis for determining an updating strategy when the indoor fan operates at low speed or medium speed. The rotating speed of the indoor fan and the frequency of the compressor are integrated for analysis, and the optimization quality of the air conditioning system is improved.

In some optional embodiments, the second parameter is an air conditioner set temperature and an outdoor ambient temperature. In the cooling mode, when the temperature difference between the outdoor environment temperature and the target set temperature of the air conditioning system is greater than the set temperature difference value, the air conditioning system is required to provide a larger cooling capacity to meet the requirements of users in unit time, and in the cooling mode, when the temperature difference between the outdoor environment temperature and the target set temperature of the air conditioning system is greater than the set temperature difference value, the air conditioning system is required to provide a larger heating capacity to meet the requirements of users in unit time. In the above situation, the load of the compressor is large, which is not suitable for determining the update strategy. The outdoor environment temperature and the target set temperature of the air conditioning system are integrated for analysis, and the optimization quality of the air conditioning system is improved.

And determining the ratio of the second parameter to the number of the equipment corresponding to different first parameter levels within a set range, and updating the control algorithm of the air conditioning system aiming at the first parameter level with the maximum ratio, namely the compressor frequency level.

The following is a method for updating an air conditioning system according to an embodiment, where an analysis needs to be performed on a reporting rate of IPM protection failures to determine whether to make an update policy and how to make the update policy. In this embodiment, the first set value is 70%, the second set value is 35%, the first parameter is the compressor frequency, and the second parameter is the indoor fan rotation speed.

Further, determining the number of air conditioning systems of each type reporting the IPM protection faults, wherein the number of IPM protection faults reported by the B type is 50, and the percentage of the IPM protection faults reported by the B type is 40%, determining the air conditioning system of the B type as an updating object, and acquiring the frequency of the temporary compressor of each B type.

The frequency grades of the B-type air conditioning system compressor frequency are classified into three grades of low, medium and high in the following table 3:

TABLE 3

As shown in table 4, the number distribution of the air conditioning system of type B with IPM protection failure at different indoor fan speeds for different compressor frequency levels is obtained by statistics:
