The embodiment provides a multi-connected air conditioner household charging method, which can be applied to a controller of a multi-connected air conditioner, and is shown in a flow chart of the multi-connected air conditioner household charging method shown in fig. 1, and mainly comprises the following steps of S102 to S108:
step S102: and obtaining a fault data packet of the multi-connected air conditioner.
The fault data packet records a fault start time and a fault end time. When the multi-connected air conditioner is charged separately, if the multi-connected air conditioner generates fault loss charging information in a certain period of time, such as when the multi-connected air conditioner is powered down by the multi-connected air conditioner household charging gateway, the data of the air conditioning unit cannot be recorded, whether each indoor unit needs to participate in charging is in an uncertain state in the period of time of occurrence of the fault, the gateway is repaired to be powered up again after the multi-connected air conditioner is in the fault state, and a fault data packet of the multi-connected air conditioner is obtained, wherein the fault data packet can be the fault data packet of the multi-connected air conditioner, and the fault starting time t s when the gateway is powered down and the fault ending time t m after the gateway is repaired to be powered up again are recorded in the fault data packet.
Step S104: and judging whether the on-off state of the indoor unit corresponding to the fault ending time is consistent with the on-off state of the indoor unit before the fault starting time.
The method comprises the steps of obtaining the on-off state of each indoor unit before the fault starting time, obtaining the on-off state of each indoor unit at the fault ending time, and judging whether the on-off state of each indoor unit at the fault ending time is completely consistent with the on-off state of each indoor unit before the fault starting time.
Step S106: if not, determining the fault duration based on the fault starting time and the fault ending time, and judging whether the fault duration is greater than a first preset duration.
If the on-off state of each indoor unit is inconsistent with the on-off state of each indoor unit before the fault starting time when the fault is ended, the indoor units with the on-off state changed exist in the period of time when the individual charging gateway is in fault, and whether each indoor unit is about to participate in charging needs to be judged. According to the fault starting time and the fault ending time recorded in the fault data packet, calculating a fault duration t=t m-ts, judging whether the fault duration t is larger than a first preset duration, wherein the value range of the first preset duration can be 5-15 min, and the optimal value is 10min.
Step S108: when the fault time length is longer than the first preset time length, judging whether each indoor unit of the multi-connected air conditioner participates in household charging in the fault time length or not based on the fault time length and the operation data of each indoor unit of the multi-connected air conditioner.
The indoor unit operation data comprise operation state data of a second preset duration before the fault starting time and operation state data of a third preset duration after the fault ending time. The value range of the second preset duration may be 2 to 5 days, preferably 3 days, and the value range of the third preset duration may be 2 to 5 days, preferably 3 days.
When the fault time of the multi-connected air conditioner generating faults is longer than the first preset time, the multi-connected air conditioner is indicated to be longer in fault time, in order to avoid great loss to users caused by directly enabling all users to share charging, operation data of each indoor unit of the multi-connected air conditioner in the first days and the later days of faults are obtained, namely the on-off state of each indoor unit in the time period is obtained, and whether each indoor unit needs to participate in charging is judged according to the operation rules of each indoor unit in the front time period and the back time period.
According to the multi-connected air conditioner household charging method, when the indoor unit starting state corresponding to the fault ending time of the multi-connected air conditioner is inconsistent with the indoor unit starting state before the fault starting time, and the generated fault duration is long, whether each indoor unit needs to participate in charging or not is judged according to the fault duration and the operation data of each indoor unit of the multi-connected air conditioner, the problem that the charging cannot be performed due to the fault of a charging system can be solved, and the accuracy and the reliability of household charging of the multi-connected air conditioner are improved.
In an embodiment, in order to further improve the accuracy of the charging of the multiple air conditioners by users, the embodiment provides an implementation manner of judging whether each indoor unit of the multiple air conditioners participates in charging in the fault duration based on the fault duration and the operation data of each indoor unit of the multiple air conditioners, and the implementation manner can be specifically implemented with reference to the following steps (1) to (2):
Step (1): and determining fault correlation factors of the indoor units based on the operation data of the indoor units of the multi-connected air conditioner.
The fault correlation factor can indicate the probability of the indoor unit operating normally in the fault duration, namely the probability of the indoor unit participating in the household charging, and when the fault correlation factor of the indoor unit is larger, the probability of the indoor unit participating in the household charging is larger. And respectively calculating fault correlation factors of each indoor unit according to the operation data of each indoor unit.
In a specific embodiment, the above-mentioned calculation formula of the fault correlation factor is z=xy;
X＝(S-1s+S-2s+…+S-Ns+S+1s+S+2s+…+S+Ns)/2N
Y＝(S-1m·S-1s+S-2m·S-2s+…+S-Nm·S-Ns+S+1m·S+1s+S+2m·S+2s+…+S+Nm·S+Ns)/(S-1s+S-2s+…S-Ns+S+1s+S+2s+…S+Ns)
Wherein, X is the probability that the indoor unit is in the on state at the fault start time, when the indoor unit is in the on state N days before the fault start time, S -Ns =1, otherwise S -Ns =0, when the indoor unit is in the on state N days after the fault start time, S +Ns =1, otherwise S +Ns =0; y is the probability that the indoor unit is still in the on state at the fault end time, when the indoor unit is in the on state N days before the fault end time, S -Nm =1, otherwise S -Nm =0, when the indoor unit is in the on state N days after the fault start time, S +Nm =1, otherwise S +Nm =0.
The correlation factor X is the probability that a user starts a certain indoor unit in the first N days and the second N days at the moment when the charging gateway breaks down, the correlation factor Y is the probability that the indoor unit is in a starting state before the starting time of the fault and is still in the starting state after the ending time of the fault in the first N days and the second N days, the denominator of Y is the number of days that the indoor unit is in the starting state before the starting time of the fault in the second N days, and the numerator of Y is the number of days that the starting states of the indoor unit are consistent before the fault and after the fault; the indoor unit is in a starting state of 1 before the fault starting time, the starting state is still 1 after the fault ending time, 1 x 1=1 is counted in the molecule, if the indoor unit is shut down after the fault, 1*0 =0 is counted out of the molecule.
By calculating the fault correlation factor according to the running states of the indoor units in the time period before and after the fault occurs, the probability that each indoor unit needs to charge separately can be accurately calculated, the separate charging accuracy of the multi-connected air conditioner when the multi-connected air conditioner fails is improved, and the multi-connected air conditioner can have charging basis even if the separate charging network is turned off, so that the separate charging is ensured to be normal.
The multi-connected air conditioner comprises indoor units P1-P3, wherein the individual charging gateway breaks down in whole at the time of 16 days of 7 months 21, and the individual charging gateway is powered on again after 20 minutes of fault restoration at the time of 16 days of 7 months 21, namely the starting time of the fault is 7 months 21, the time of 16 days is whole, and the ending time of the fault is 7 months 21, and the time of the fault is 20 minutes. Calculating fault correlation factors Z of each indoor unit respectively, wherein if the whole indoor unit P1 is in a starting state when the indoor unit is in a 7-month 20-day 16 state, S -1s =1, and if the whole indoor unit P1 is in a shutdown state when the indoor unit is in a 7-month 19-day 16 state, S -2s =0; if the whole indoor unit P1 is in the on state at 7 months, 22 days and 16 days, then S +1s =1; if the 20-component indoor unit P1 is in the shutdown state for 7 months, 20 days and 16 hours, then S -1m =0; if the 20-component indoor unit P1 is in the on state at 7 months, 22 days and 16 hours, S +1m =1.
Step (2): and judging whether each indoor unit participates in household charging in the fault time based on the fault correlation factor of each indoor unit.
When the fault correlation factor of the indoor unit is larger, the probability that the indoor unit is in a starting state in the fault duration or the duration is larger is indicated, and the indoor unit is determined to be required to participate in household charging. By calculating the fault correlation factor of each indoor unit according to the operation data of the indoor units, the probability that each indoor unit is in an operation state in the fault duration can be judged according to the operation rule of each indoor unit of the multi-connected air conditioner, and whether each indoor unit needs to participate in charging in the fault duration can be judged, so that the reasonability of user apportionment charging is improved.
In a specific embodiment, a threshold value of a fault correlation factor may be set, and when the fault correlation factor is greater than a preset threshold value and the fault time is greater than a first preset duration and less than a fourth preset duration, the indoor unit is determined to participate in household charging in the fault duration; when the fault correlation factor is smaller than a preset threshold value and the fault time is longer than the first preset time period and shorter than the fourth preset time period, determining that the indoor unit does not participate in household charging in the fault time period.
The value range of the fourth preset duration may be 30-90 min, the preset threshold may be considered as a setting adjustment, the number of indoor units participating in the user sharing charging may be correspondingly changed when the size of the preset threshold is adjusted, and the value range of the preset threshold may be, for example, 0.5-0.8, and the preferred value is 0.5.
When the fault time length of the multi-connected air conditioner generating faults is longer than the first preset time length and smaller than the fourth preset time length, if the fault correlation factor of the indoor unit is calculated to be greater than a preset threshold value, the indoor unit is indicated to be in a use state in the fault time length with high probability, and the indoor unit is determined to participate in household charging; if the calculated fault correlation factor of the indoor unit is smaller than the preset threshold, the indoor unit is in a shutdown state with high probability in the fault duration, and the indoor unit is determined not to participate in household charging. In practical application, after judging all indoor units needing to participate in household charging in the multi-connected air conditioner, the indoor units participating in household charging can uniformly spread the power consumption of the air conditioner in the fault time period, or the power consumption of the air conditioner in the fault time period can be spread according to the gear sizes of the indoor units in the time period before and after the fault.
And when the fault correlation factor is large, determining that the indoor unit needs to participate in household charging, so that an electric charge allocation mode in a fault period is automatically adjusted according to the use habit of a user, the probability of the operation data of the indoor unit is also based, and the reliability of the user allocation charging in the fault period is improved.
In one embodiment, in order to improve the accuracy of household charging, the household charging method for the multi-connected air conditioner provided in this embodiment further includes: and when the fault correlation factor is larger than a preset threshold value and the fault time is longer than a fourth preset duration, carrying out household charging on each indoor unit based on a manager decision.
When the fault duration of the multi-connected air conditioner fault is longer, the indoor units are determined to participate in household charging according to the fact that the correlation factor is larger than the preset threshold, but because the fault duration is longer, in order to avoid loss caused by unreasonable data correction, after the data correction is carried out according to the correlation factor, household charging final decision can be carried out by combining judgment of management personnel, wherein the household charging decision can be for example, the electricity fee generated by the fault duration is amortized as a data correction result (namely, the indoor units with the correlation factor larger than the preset threshold are amortized), or the amortization mode can be selected by the property according to the condition of using the air conditioner (such as indoor area or room position) by the user.
In one implementation manner, the multi-connected air conditioner household charging method provided by the embodiment further includes: if the indoor units with the switching-on and switching-off states at the fault ending time and the switching-on and switching-off states before the fault starting time are consistent, the indoor units which are in the starting-up state before and after the fault are controlled to be charged in the fault duration.
When the on-off state of each indoor unit after the fault repair is completed is completely consistent with the on-off state of each indoor unit before the fault starts, the running state of each indoor unit is not changed within the fault duration. If a certain indoor unit is in a starting state before and after the occurrence of a fault, indicating that the indoor unit is in the starting state in the fault duration, and determining that the indoor unit is normally connected with the fault duration charging; if a certain indoor unit is in a shutdown state before and after the occurrence of a fault, the indoor unit is in the shutdown state within the fault duration, and the indoor unit does not need to participate in household charging within the fault duration.
The indoor units in the starting state are controlled to charge according to normal connection, namely the indoor units in the starting state before and after the fault occurs participate in household charging, so that the self-correction of fault data is realized, and the normal charging in the fault duration is ensured.
In one implementation manner, the multi-connected air conditioner household charging method provided by the embodiment further includes: when the fault duration is smaller than the first preset duration, the indoor unit which determines that the switching-on and switching-off state of the fault ending time is inconsistent with the switching-on and switching-off state before the fault starting time does not participate in charging. When the fault duration of the multi-connected air conditioner generating faults is smaller than the first preset duration, the time for the air conditioner generating faults is short, if the indoor unit switching on and off states corresponding to the fault ending time are inconsistent with the indoor unit switching on and off states before the fault starting time, the switching on and off states of the indoor units can be changed just due to the short fault duration, and the indoor units with inconsistent switching on and off states before and after the faults can be controlled not to participate in household charging in the fault duration.
The multi-connected air conditioner household charging method provided by the embodiment can carry out self-correction on the data after the multi-connected air conditioner household charging network turns off the power failure, solves the problem that household charging cannot be carried out when the gateway is powered off, improves the charging accuracy and reliability when the failure occurs, ensures normal household charging even if the network turns off the power, has higher implementation performance of the power failure data self-correction scheme, can be applied to a low-power MCU compared with a method based on neural network screening, and reduces the MCU operation burden.
Corresponding to the multi-connected air conditioner individual charging method provided by the above embodiment, the embodiment of the present invention provides an example of performing self-correction on the power-off data of the multi-connected air conditioner individual charging network by applying the multi-connected air conditioner individual charging method, see a multi-connected air conditioner gateway fault individual charging flow chart shown in fig. 2, and specifically can be executed with reference to the following steps:
and step 1, repairing the gateway and electrifying again after the gateway fails to obtain a gateway failure data packet.
Step 2, the repaired re-power-up time is defined as a fault end time t m, the last time of the gateway fault record is defined as a fault start time t s, and the fault time t=t m-ts is calculated.
And 3, judging the size of the fault time t, wherein the fault time range is divided into three types, namely less than 10min, more than 10min, but less than 30min and more than 30min.
And step 4, judging whether the on-off state of the indoor unit is consistent with the on-off state before the fault after the fault is over, charging according to the normal connection time if the on-off state of the indoor unit is consistent with the on-off state before the fault after the fault is over, and executing the step 5 to correct the data if the on-off state of the indoor unit is inconsistent with the on-off state before the fault.
Step 5, the data correction method is as follows:
When the fault time is longer than 10min, the on-off state of the same time period of the first three days and the last three days in the indoor unit operation record data is read, and a fault correlation factor Z=XY is calculated;
Correlation factor x= (S -1s+S-2s+S-3s+S+1s+S+2s+S+3s)/6; the correlation factor X is the internal machine startup probability of the user at the same moment when the gateway power failure occurs in the first three days and the last three days.
Correlation factor Y＝(S-1m·S-1s+S-2m·S-2s+S-3m·S-3s+S+1m·S+1s+S+2m·S+2s+S+3m·S+3s)/(S-1s+S-2s+S-3s+S+1s+S+2s+S+3s); correlation factor Y is the probability that the indoor unit is still in the on state after the on state fault is resolved in the 6 days before the gateway fault in the first three days and the last three days. (Y's denominator is the number of days in which the indoor unit is in the on state before the fault start time in 6 days, Y's numerator is the number of days in which the on state is consistent after the fault before the fault, 1 is started before the fault, 1 is still 1 when the indoor unit is started after the fault is removed, 1 x 1 = 1 is counted in the numerator, 1*0 = 0 is counted if the indoor unit is shut down after the fault, and the numerator is not counted).
Referring to the data correction flow chart shown in fig. 3, after entering the data correction flow chart, a fault correlation factor z=xy is calculated, whether z=xy is greater than a set threshold is judged, when Z is greater than the set threshold, the indoor unit is determined to participate in the individual charging, and when Z is less than the set threshold, the indoor unit is determined not to participate in the individual charging.
The set threshold may be 0.5, when Z is greater than 0.5, it indicates that the user has a high probability of being in a use state at the fault stage, and although the indoor unit is in a shutdown state after the fault is over, the user still has a high probability of being in use in the fault time in combination with daily use, and the 0.5 value is adjustable, and if the manager heightens the threshold, the number of users allocated can be increased. The indoor unit participates in charging when Z is greater than 0.5 (threshold set), and does not participate in charging when Z is less than or equal to 0.5 (threshold set).
The manager decides as an extreme case, if the fault time is too long, the data correction is not reasonable (when the fault time exceeds 180 min), and after the data correction is finished, the manager is combined to judge the final decision, and the decision is divided into two modes, namely, the electricity fee generated by the fault time is defaulted as the data correction result to be allocated, and the allocation mode is selected by the property.
For example, the individual charging gateway is set to generate faults at the point of 8:30 on the 6 month and 10 day, and the fault repair of the gateway is completed at the point of 8:50 on the 6 month and 10 day; the indoor unit of the user A is in a starting state at the 8-point 30-branch indoor unit of the period, the indoor unit is in a shutdown state after the 8-point 50-branch gateway is repaired, the actual fault time is longer than 10 minutes and smaller than 30 minutes, the intermediate interval time is too long, and the use state of the user in the fault period is directly ignored, so that the charging is inaccurate. The usage habits of the user should be comprehensively considered, and the same period of three days after three days before the fault starting time: 8 points on 6 months and 9 days 30 minutes, 8 points on 6 months and 8 days 30 minutes, 8 points on 6 months and 7 days 30 minutes, 8 points on 6 months and 11 days 30 minutes, 8 points on 6 months and 12 days 30 minutes, and 8 points on 6 months and 13 days 30 minutes. Three days after the end of fault time, three days before and three days after the end of fault time: 6 month 9 day 8 point 50 minutes, 6 month 8 day 8 point 50 minutes, 6 month 7 day 8 point 50 minutes, 6 month 11 day 8 point 50 minutes, 6 month 12 day 8 point 50 minutes, 6 month 13 day 8 point 50 minutes. Assuming that the 12 time-corresponding states of the internal machine are S-1s＝1、S-2s＝1、S-3s＝0、S+1s＝1、S+2s＝0、S+3s＝1、S-1m＝1、S-2m＝1、S-3m＝0、S+1m＝0、S+2m＝0、S+3m＝1., the correlation factor is x= (1+1+0+1+0+0+1)/6=4/6, and the correlation factor y= (1×1+1+0+1×0+1×0+0+1×1)/(1+1+0+1+0) =3/4. Then z=1/2=0.5 is less than or equal to 0.5 and the indoor unit does not participate in the individual charging.
