The operation phase of the air conditioner or the central air conditioner comprises the following steps: in the embodiment of the disclosure, the current health index value corresponding to the operation stage can be determined according to the indoor temperature value of the region where the operation stage of the air conditioner is located, the optimal health index value is obtained through historical comparison, the current health index value is scored, the current health score of the operation stage is obtained, and the air conditioner health degree assessment can be realized.
Fig. 1 is a schematic diagram of an architecture for an air conditioner health assessment scenario according to an embodiment of the present disclosure. As shown in fig. 1, the scenario may include: an air conditioning outdoor unit 100, one, two or more air conditioning indoor units 200, and a cloud server 300.
Each air-conditioning indoor unit 200 can be respectively connected with the outdoor unit 100 to form a corresponding air-conditioner capable of adjusting the temperature and humidity of the area where the indoor unit is located, and each air-conditioning indoor unit 200 can be in communication connection with the cloud server 300, i.e. each air-conditioner can be in communication connection with the cloud server 300.
In this way, the cloud server 300 may obtain the operation state parameters of each air conditioner, including: indoor temperature value, operating mode, target temperature, etc. Therefore, the corresponding current operation stage can be determined according to the current indoor temperature value of the area where the air conditioner to be evaluated is located, the corresponding current health index value is obtained, then the optimal health index value is obtained through historical comparison, the current health index value is scored, the current health score of the operation stage is obtained, and the air conditioner health degree evaluation can be achieved. And then can carry out reasonable maintenance to the air conditioner according to the health degree grade of air conditioner, further improve the life of air conditioner.
Therefore, the cloud server can evaluate the health degree of the air conditioner and perform corresponding maintenance. Fig. 2 is a flowchart of a method for evaluating the health of an air conditioner according to an embodiment of the present disclosure. As shown in fig. 2, the process of air conditioner health evaluation includes:
step 201: and acquiring a current indoor temperature value of the area where the air conditioner to be evaluated is located, and determining a current operation stage matched with the current indoor temperature value.
The air conditioner for starting up operation comprises: indoor unit and outdoor unit. The air conditioner to be subjected to health degree evaluation is an air conditioner to be evaluated. Therefore, real-time or timing communication can be carried out with the air conditioner to be evaluated, and the cloud server obtains the indoor temperature value of the area where the air conditioner to be evaluated is located, wherein the current moment corresponds to the current indoor temperature value.
The operation phase of the air conditioner comprises the following steps: a start-up phase, a constant temperature phase, a shutdown phase, etc., wherein a current operational phase of the air conditioner may be determined based on a current indoor temperature value, and in some embodiments, determining a current operational phase that matches the current indoor temperature value includes: under the condition that the current indoor temperature value is not in the set range of the target temperature value, determining that the current operation stage is a starting operation stage; and under the condition that the current indoor temperature value is within the set range of the target temperature value, determining that the current operation stage is a constant-temperature operation stage.
Generally, when the air conditioner in the current operation mode is started and operated, the current indoor temperature value cannot reach the temperature, namely, the current indoor temperature value is not in the set range of the target temperature value, and the current operation time cannot be long, namely, the current operation time is smaller than the set value. Thus, in some embodiments, determining a current operating phase that matches a current indoor temperature value includes: under the condition that the current indoor temperature value is not in the set range of the target temperature value and the current running time is smaller than the set value, determining that the current running stage is a starting running stage; and under the condition that the current indoor temperature value is within the set range of the target temperature value, determining that the current operation stage is a constant-temperature operation stage. Thus, the accuracy of the air conditioner operation stage determination is further improved.
Wherein the current operation mode includes: the operation modes such as a heating mode, a cooling mode, a dehumidifying mode and the like can be set to be 3min,5min,10min, 15min or the like. The target temperature value may be set to be within a range of Tt+ -0.3deg.C, tt+ -0.5deg.C, or Tt+ -1deg.C, etc. For example: if the current indoor temperature Te is not within the Tt+/-0.5 ℃ range and the current running time is less than 10 minutes, the current running stage can be determined to be the starting-up running stage. If Te is within Tt+/-0.5 ℃, the current indoor temperature value is indicated to be warm, and therefore, the current operation stage can be determined to be a constant-temperature operation stage.
Step 202: and determining a current health index value corresponding to the current operation stage according to the current indoor temperature value.
Generally, different run phases correspond to different health index values. In some embodiments, under the condition that the current operation stage is a startup operation stage, obtaining a corresponding temperature change rate according to the current indoor temperature value and the indoor temperature value obtained in the current operation time, and determining the maximum temperature change rate in the current operation time as a current health index value; under the condition that the current operation stage is a constant temperature operation stage, according to the current indoor temperature value, setting an indoor temperature value acquired in a time period and a target temperature value, obtaining corresponding temperature stability, and determining an optimal value or an average value among the obtained temperature stability as a current health index value.
In the startup operation stage, the cloud server may not only obtain the operation state parameters uploaded by the air conditioner, but also include: indoor temperature value, and may further include: operation mode. The cloud server can acquire the running state parameters uploaded by the air conditioner in real time or at regular time and record the running state parameters, so that at the current moment, the cloud server can not only acquire the corresponding current indoor temperature value, but also acquire the indoor temperature value in the current running time, namely, the acquisition of the indoor temperature value comprises the following steps: te1, te2, … … and Ten, wherein Ten is a current indoor temperature value, and the air conditioner can acquire the interval of indoor environment temperature according to the uploading time interval of the air conditioner to obtain the corresponding acquisition time t between each indoor temperature value, so that the corresponding temperature change rate can be obtained according to the indoor temperature value, the current operation mode and the corresponding acquisition time. For example: the temperature change rate bvi=Δti/Δti, where i may be 1,2 … … n, and Δti may be (ti+1-Ti), and the corresponding Δti may be (ti+1-Ti), or Δti may be (ti+3-Ti), and the corresponding Δti may be (ti+3-Ti), and so on.
In some embodiments, obtaining the corresponding rate of temperature change comprises: according to the current indoor temperature value, the current running mode and the indoor temperature value acquired in the current running time, the corresponding temperature rise rate or temperature drop rate is obtained by fitting a curve slope; or obtaining a corresponding temperature rise rate or temperature drop rate by regression analysis according to the current indoor temperature value, the current running mode and the indoor temperature value acquired in the current running time. The accuracy of the temperature change rate can be improved by a curve slope fitting mode or a regression analysis mode, and the accuracy of the health index value is further improved.
By the time the current run time is reached, one, two or more temperature change rates bvi may be obtained, and the maximum temperature change rate may be determined as the current health indicator value for the on-run phase.
In the constant temperature operation stage, the cloud server may not only obtain the operation state parameters uploaded by the air conditioner, but also include: indoor temperature value, and may further include: an operating mode, a target temperature, etc. In this way, the set period may be 1min, 2min, 3min, or 5min, and the n obtained indoor temperature values may be Te1, te2, … …, ten, respectively, in the set period taking the current time as the end point, where Ten is the current indoor temperature value and the target temperature is Tt, so that the current temperature stability may be obtained by the formula (1).
VT ＝ Σ(Tei - Tt)2 / n (1)
Where V T is the current temperature stability, te i may be consistent with Tei, and i=1, 2 … … n, tt is the target temperature, which is the collected indoor temperature value in the set time period with the current time as the end point.
And in the previous set time period, the corresponding temperature stability is also obtained, so that the optimal value of the temperature stability is selected from the obtained temperature stability and is determined as the current health index value, or the obtained temperature stability is subjected to average operation to obtain the corresponding temperature stability average value and can be determined as the current health index value.
Step 203: and scoring the current health index value according to the current health index reference value matched with the current operation stage to obtain the current health score of the current operation stage, wherein the current health index reference value is an optimal value in the historical health index value.
Also, different operation phases correspond to different health index reference values, and in the embodiment of the disclosure, the corresponding health index reference values may be determined according to historical health index values.
In actual use, the health degree of the air conditioner is necessarily in a descending trend under the condition that the air conditioner is not maintained, and according to the rule, under the same operation mode, the optimal health index value is taken as the health index reference value, and the current health index value obtained each time can be stored. Therefore, after determining the current health index value corresponding to the current operation phase, the stored health index value may be compared, and the optimal health index value may be used as the health index reference value. In some embodiments, the current health indicator value is updated to the current health indicator value if the current health indicator value is better than the current health indicator value.
Of course, in the case that the current health index value is not better than the current health index reference value, the current health index reference value is not changed.
And then, scoring the current health index value according to the current health index reference value matched with the current operation stage to obtain the current health score of the current operation stage. For example: the health index value is JKi, and the corresponding current health index reference value is JKj. The health index value may be a temperature change rate or a temperature stability.
TABLE 1
Table 1 is a correspondence relationship between a health index value and a health score provided by an embodiment of the present disclosure. For example, the current health index value JKi = JKj (1-8%), i.e., the corresponding current health score may be determined to be 90 points according to table 1. The corresponding health index reference value is determined according to the historical health index value, and the health degree of the air conditioner is always in a descending trend under the condition that the air conditioner is not maintained in actual use, so that the optimal health index value obtained in the running process of the air conditioner is determined as the health index reference value, the health index reference value is not changed after a period of time, and meanwhile, the fluctuation range of the corresponding health index value in a certain period of time after the reference value can be taken as a threshold value. And the health degree evaluation can be carried out on the current health index value according to the threshold value, wherein the threshold value corresponds to 100 points, and corresponds to 0 points when the air conditioner is damaged and has no effect. For example: the current health index value JKd is JKj worse than the current health reference value, and the running time corresponding to the current time is less than the preset threshold time, then the range of (JKd, JKj) can be given, the corresponding health score is 100, and so on.
Therefore, there are various ways to score the current health index value according to the current health index reference value matched with the current operation stage, so as to obtain the current health score of the current operation stage. Specifically, this is not the case.
The current health score of the current operation stage is obtained, the current health score can be directly determined as the health score of the air conditioner to be evaluated, and corresponding air conditioner maintenance and management can be carried out, so that the service life of the air conditioner is prolonged.
Or in some embodiments, further comprising: determining a health score corresponding to each of the operational phases; and obtaining the health degree score of the air conditioner to be evaluated according to each health score and the corresponding weight coefficient. And determining the minimum value in the current health scores obtained in the starting-up operation stage as the health score corresponding to the starting-up stage, for example: 90 minutes, the minimum value in the current health scores obtained in the constant temperature operation stage is determined as the health score corresponding to the constant temperature stage, for example: 85min, the weight coefficient corresponding to the start-up stage is 0.4, the weight coefficient corresponding to the constant temperature stage is 0.6, and the health degree score of the air conditioner to be evaluated is=90×0.4+85×0.6=87.
Therefore, in the embodiment of the disclosure, according to the indoor temperature value of the area in the operation stage of the air conditioner, the current health index value corresponding to the operation stage can be determined, the optimal health index value is obtained through historical comparison, the current health index value is scored, the current health score of the operation stage is obtained, and the air conditioner health degree assessment can be realized, so that the air conditioner health degree assessment can be carried out by only monitoring few parameters such as the environment temperature and the operation mode, and the like, the corresponding scoring adaptation for the model of the air conditioner is not needed, the application difficulty of the air conditioner health degree assessment is greatly reduced, the air conditioner can be more easily reasonably maintained according to the health degree grade of the air conditioner, and the service life of the air conditioner is further prolonged.
Since the corresponding health index reference value is determined according to the historical health index value, the current health index value is required to be stored each time. Thus, in some embodiments, determining the current health indicator value corresponding to the current run phase further comprises: obtaining and storing a current health index array according to the current health index value, wherein the current health index array comprises: current health index value, time, operating mode, target temperature, start initial temperature, etc. Therefore, the method is convenient for subsequent quick determination of the health index reference value and the corresponding health score by storing in an array mode, and the maintenance and management efficiency of the air conditioner is further improved.
The following integrates the operation flow into a specific embodiment, and illustrates the process for evaluating the health of an air conditioner provided by the embodiment of the invention.

The stage evaluation module 430 is configured to score the current health index value according to a current health index reference value matched with the current operation stage, so as to obtain a current health score of the current operation stage, wherein the current health index reference value is an optimal value in the historical health index value.
In some embodiments, the acquisition determination module 410 includes:
A stage determining unit configured to determine that the current operation stage is a startup operation stage in a case where the current indoor temperature value is not within the set range of the target temperature value and the current operation time is smaller than the set value; and under the condition that the current indoor temperature value is within the set range of the target temperature value, determining that the current operation stage is a constant-temperature operation stage.
In some embodiments, the metric determination module 420 includes:
the first determining unit is configured to obtain a corresponding temperature change rate according to the current indoor temperature value and the indoor temperature value acquired in the current operation time when the current operation stage is the starting operation stage, and determine the maximum temperature change rate in the current operation time as the current health index value.
The second determining unit is configured to obtain a corresponding temperature stability according to the indoor temperature value acquired in the set time period and the target temperature value when the current operation stage is the constant temperature operation stage, and determine an optimal value or an average value among the obtained temperature stability as a current health index value.
In some embodiments, the first determining unit is specifically configured to obtain, according to the current indoor temperature value, the current operation mode, and the indoor temperature value obtained in the current operation time, a corresponding temperature rise rate or temperature drop rate by fitting a slope of a curve; or obtaining a corresponding temperature rise rate or temperature drop rate by regression analysis according to the current indoor temperature value, the current running mode and the indoor temperature value acquired in the current running time.
In some embodiments, the metric determination module 420 further includes:
The array storage unit is configured to obtain and store a current health index array according to the current health index value, wherein the current health index array comprises: current health index value, time, operating mode, target temperature, start initial temperature, etc.
In some embodiments, further comprising:
and the reference updating module is configured to update the current health index value to the current health index value under the condition that the current health index value is better than the current health index value.
In some embodiments, further comprising:
A weighted evaluation module configured to determine a health score corresponding to each of the operational phases; and obtaining the health degree score of the air conditioner to be evaluated according to each health score and the corresponding weight coefficient.
The air-conditioning health evaluation process for the air-conditioning health evaluation device is further described below with reference to the embodiments.
In this embodiment, as shown in fig. 1, there are a plurality of air conditioning indoor units, and the following description will take one air conditioning indoor unit as an example of an air conditioner to be evaluated, where the setting range of the target temperature value may be tt±0.5 ℃, and the setting period may be 3min.
Fig. 5 is a schematic structural diagram of an air conditioner health assessment device according to an embodiment of the present disclosure. As shown in fig. 5, the air conditioner health evaluation device 400 includes: the acquisition determining module 410, the index determining module 420, the stage evaluating module 430, the reference updating module 440, and the weighting evaluating module 450, and the acquisition determining module 410 includes: the stage determination unit 411. The index determination module 420 includes: a first determination unit 421, a second determination unit 422, and an array holding unit 423.
In this embodiment, after the obtaining determining module 410 obtains the current operation state parameter uploaded by the air conditioner to be evaluated, if the current indoor temperature value in the current operation state parameter is not within tt±0.5 ℃, and the current operation time in the current operation state parameter is less than 10min, the stage determining unit in the obtaining determining module 410 may determine that the current operation stage is the startup operation stage. At this time, the first determining unit 421 in the index determining module 420 may obtain a corresponding temperature change rate by means of regression analysis according to the current indoor temperature value, the current operation mode, and the indoor temperature value obtained in the current operation time, and determine the maximum temperature change rate in the current operation time as the current health index value, and the array storing unit 423 may obtain and store the current health index array in the startup operation stage according to the current health index value.
Of course, if the current indoor temperature value in the current operation state parameter is within tt±0.5 ℃, the phase determining unit in the acquisition determining module 410 may determine that the current operation phase is a constant temperature operation phase. At this time, the second determining unit 421 in the index determining module 420 sets the indoor temperature value acquired in the period of time and the target temperature value according to the current indoor temperature value, obtains the corresponding temperature stability, and determines the average value between the obtained temperature stability as the current health index value. The array storing unit 423 obtains and stores the current health index array of the constant temperature operation stage according to the current health index value.
After the current health index array is stored, the current health index reference value matched with the current operation stage can be determined according to the historical health index value. Wherein, if the current health indicator value is better than the current health indicator reference value, the reference update module 440 may update the current health indicator reference value to the current health indicator value.
Thus, the phase evaluation module 430 may score the current health index value according to the current health index reference value that matches the current operation phase, resulting in a current health score for the current operation phase, e.g., may determine the current health score that matches the current health index value according to a table.
In this way, the weighting evaluation module 450 may determine the health score corresponding to the startup operation stage according to the current health score of the startup operation stage, determine the health score corresponding to the constant temperature operation stage according to the current health score of the constant temperature operation stage, and perform the weighting operation according to the corresponding weighting coefficient to obtain the health score of the air conditioner to be evaluated.
It can be seen that, in this embodiment, the device for evaluating the health degree of an air conditioner may determine the current health index value corresponding to each operation stage according to the indoor temperature value of the region where the operation stage of the air conditioner is located, score the current health index value by comparing the historic values to obtain the current health score of each operation stage, and then obtain the health score of the air conditioner according to the health score of each operation stage and the corresponding weight coefficient, that is, the air conditioner health degree evaluation is achieved.
