Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. The components of the embodiments of the present application generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the application, as presented in the figures, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures.
Furthermore, the terms "first," "second," and the like, if any, are used merely for distinguishing between descriptions and not for indicating or implying a relative importance.
It should be noted that the features of the embodiments of the present application may be combined with each other without conflict.
The voltage qualification rate is the statistical data of the ammeter or the power terminal to the voltage. For electricity meters, tables 645 and 698 are both statistics that support voltage yield.
In the Data Identifier (DI) in table 645, 0x03100000 to 0x0310030C are DI related to the voltage yield. For example, 0x03100100 is the current month a phase voltage qualification rate statistical data, and the statistical data include: the method comprises the steps of monitoring the A-phase voltage, passing the A-phase voltage percent of pass, passing the A-phase voltage percent of limit, passing the A-phase voltage to the upper limit, passing the A-phase voltage to the lower limit, and passing the A-phase voltage to the upper limit, and passing the A-phase voltage to the lower limit.
In the object identifier (abbreviated as OI) in the 698 table, 0x2131 to 0x2133 are OI related to the voltage yield. For example, 0x21310200 (specific attribute 2 of object identifier, which is called object attribute descriptor, abbreviated as OAD), is the voltage qualification rate of phase a of the month, and the statistical data of the voltage qualification rate of the month include the voltage qualification rate of the current day and the voltage qualification rate of the current month, which are specifically defined in the following table:
the parameters of the voltage qualification rate are defined in 0x40300200, and are specifically defined in the following table:
the voltage qualification rate needs to be counted according to the voltage qualification rate parameter, and is usually counted once per minute, namely, the time interval between two times of counting is 1 minute. In general, the voltage exceeds the upper limit of voltage check or the lower limit of voltage check is not required to be counted, and the voltage is required to be counted within the upper limit of voltage qualification and the lower limit of voltage qualification.
When the voltage is within the upper limit of the voltage qualification and the lower limit of the voltage qualification, namely the voltage is effective, the voltage monitoring time of the day and the month is increased by 1 minute, the voltage exceeding the upper limit of the voltage is meant to exceed the upper limit of the voltage qualification but not exceed the upper limit of the voltage qualification, and the voltage exceeding the lower limit of the voltage is meant to be lower than the lower limit of the voltage qualification but higher than the lower limit of the voltage qualification. Voltage out-of-limit ratio = voltage out-of-limit duration/voltage monitoring duration, voltage qualification ratio equals = 100% -voltage out-of-limit ratio.
The power terminal clears the voltage qualification rate of the current day at the point 0, and clears the voltage qualification rate of the current month at the point 0 of the 1 day of the beginning of the month. When the time of the power terminal changes, it is generally time-aligned in the future, for example, time-aligned to 23 minutes at the current day. The terminal needs to increment the voltage monitoring duration, the increment value is the time difference between the last statistical time and the current time, and the voltage in the time range is regarded as qualified.
The defects of the prior art are as follows:
(1) The power terminal changes the time after being powered on again due to sudden power failure, and the voltage monitoring time is increased by the power failure time, and the voltage qualification rate obtained based on the voltage monitoring time is higher than the actual result because the power terminal has no voltage.
(2) The power terminal increases the voltage monitoring duration, whether the last statistical time and the current statistical time are just 1 minute apart or not can be judged, if the last statistical time and the current statistical time are not equal to 1 minute, the power terminal can judge that the power terminal has time setting operation, the current day voltage monitoring duration can be increased by 1 minute, and the voltage monitoring thread often has an error within 3 seconds, so that the power terminal can erroneously judge that the power terminal has time setting operation.
(3) The power terminal is generally three-phase voltage, and when a certain phase is not electrified, there are cases that the voltage is not available on the same day but the actual voltage monitoring time is not 0.
(4) After the power terminal performs time setting operation, the voltage monitoring time of the A/B/C three-phase voltage can change in a jumping manner, and whether the three-phase voltage is electrified is not considered.
(5) Since the voltage qualification rate is equal to 100% -the voltage out-of-limit rate, if the voltage out-of-limit period is 0, the voltage monitoring period is also 0, meaning that the voltage qualification rate is equal to 100%, it is not practical.
In order to overcome the influence of the statistical accuracy of the voltage qualification rate caused by the above situation, the embodiment of the application provides a statistical method of the voltage qualification rate, which will be described in detail below.
Referring to fig. 1, the voltage qualification rate statistical method includes steps S101 to S104.
S101, reading the counted voltage qualification rate data of the target voltage.
The counted voltage qualification rate data comprises a voltage qualification rate and a voltage monitoring duration for calculating the voltage qualification rate.
The target voltage may be an a-phase voltage, a B-phase voltage, or a C-phase voltage of the a/B/C three-phase voltages.
In the embodiment of the application, 3 voltage qualification rate statistics threads (the execution frequency is 1 minute) are started, each thread is the same section of program which is executed, the parameters received by the section of program are sequence numbers of voltages, and 0, 1 and 2 respectively represent A-phase voltage, B-phase voltage and C-phase voltage.
And entering any phase voltage monitoring thread, if the voltage sequence number of the phase voltage is in the effective range (namely 0-2), judging whether the phase voltage is effective, namely whether the phase voltage is in the upper limit of voltage qualification and the lower limit of voltage qualification, taking the phase voltage as a target voltage under the condition that the phase voltage is effective, and reading the counted voltage qualification rate data of the phase voltage.
It can be appreciated that the counted voltage qualification rate data includes a time range corresponding to the voltage qualification rate from the preset start time to the last counted time.
Since the voltage qualification rate includes the current day voltage qualification rate and the current month voltage qualification rate, the preset starting time is 0 point on the current day for the current day voltage qualification rate, and is 0 point on the current month 1 for the current month voltage qualification rate.
It should be noted that when the current statistical time is 0 time-sharing of 0 point on the same day, the current voltage qualification rate needs to be cleared, and when the current statistical time is 0 time-sharing of 0 point on the same day 1 month, the current voltage qualification rate needs to be cleared.
S102, determining an updating mode of the voltage monitoring duration according to whether the difference value between the current statistical time and the last statistical time is in a preset interval or not under the condition that the target voltage is in a preset checking range and the current statistical time is not the preset starting time.
The preset assessment range is determined by a lower voltage assessment limit and an upper voltage assessment limit, wherein the lower voltage assessment limit is lower than a lower voltage qualification limit, and the upper voltage assessment limit is higher than the upper voltage qualification limit.
The target voltage being within the preset checking range means that the target voltage is not lower than the lower limit of the voltage checking and not higher than the upper limit of the voltage checking.
In a possible implementation, the preset interval is [57 seconds, 63 seconds ], and the updating mode of the voltage monitoring duration can be determined according to whether the difference between the current statistical time and the last statistical time is within 57 seconds to 63 seconds. Therefore, the error in 3 seconds caused by the voltage monitoring thread can be avoided, and when the time interval between the two statistics of the power terminal is not 1 minute, the power terminal can directly judge that the power terminal has time-setting operation, and the voltage monitoring time length is increased by 1 minute.
Alternatively, step S102 may include substeps S102-1 through S102-4.
S102-1, if the difference between the current statistical time and the last statistical time is within the preset interval, the updating mode of the voltage monitoring duration is that a fixed value is increased.
S102-2, if the difference value between the current statistical time and the last statistical time is not in the preset interval, judging whether a time setting event occurs in the preset time period.
Wherein, if the time setting event occurs, step S102-3 is performed, and if the time setting event does not occur, step S102-4 is performed.
S102-3, the updating mode of the voltage monitoring duration is that a non-fixed value is increased.
S102-4, the updating mode of the voltage monitoring duration is that a fixed value is increased.
In a possible implementation, the preset interval is [57 seconds, 63 seconds ], and the preset period is 90 seconds nearest to the current statistical time.
There are two cases in which the update manner of the voltage monitoring duration is increased by a fixed value, namely, "the difference between the current statistical time and the last statistical time is within [57 seconds, 63 seconds ], and" the difference between the current statistical time and the last statistical time is not within [57 seconds, 63 seconds ], respectively, and a time-setting event occurs at the power terminal within 90 seconds nearest to the current statistical time.
There is a case where the voltage monitoring period is updated in such a manner that the non-fixed value is increased, that is, "the difference between the current statistical time and the last statistical time is not within [57 seconds, 63 seconds ], and no time-lapse event occurs in the power terminal within 90 seconds nearest to the current statistical time".
And S103, updating the voltage monitoring duration according to an updating mode.
Alternatively, step S103 may include substeps S103-1 through S103-2.
S103-1, if the updating mode is that the fixed value is increased, the voltage monitoring time length is increased according to the preset value.
In a possible implementation, the preset value may be 1 minute, i.e. both the current day voltage monitoring period and the current month voltage monitoring period are increased by 1 minute.
And S103-2, if the updating mode is that the non-fixed value is increased, the voltage monitoring time length is increased according to the difference value between the current statistical time and the last statistical time.
It can be understood that the current statistical time and the last statistical time are both the current daily voltage monitoring time and the current monthly voltage monitoring time.
Referring to fig. 2, before step S104, the voltage qualification rate statistical method further includes step S105.
S105, if the updated voltage monitoring time length is greater than the difference value between the current statistical time and the preset starting time, resetting the updated voltage monitoring time length to be the difference value between the current statistical time and the preset starting time.
In a possible implementation, the preset starting time is 0 point on the current day for the current day voltage qualification rate, and is 0 point on the current month 1 day for the current month voltage qualification rate.
And if the updated current day voltage qualification rate is larger than the difference value between the current statistical time and the current day 0 point, resetting the updated current day voltage qualification rate as the difference value between the current statistical time and the current day 0 point.
And if the updated current month voltage qualification rate is larger than the difference value between the current statistical time and 0 point of 1 day of the month, resetting the updated current month voltage qualification rate as the difference value between the current statistical time and 0 point of 1 day of the month.
The updated voltage monitoring time length is compared with the difference value between the current statistical time and the preset starting time, so that the influence of the change of the time of the power terminal after the power terminal is powered on again due to sudden power failure on the voltage monitoring time length is avoided.
The counted voltage qualification rate data also comprises a voltage upper time period and a voltage lower time period, and the voltage upper time period and the voltage lower time period are also used for calculating the voltage qualification rate, so that the voltage upper time period and the voltage lower time period also need to be updated.
In contrast, referring to fig. 3, before executing step S104, the voltage qualification rate statistical method further includes step S106 in parallel with step S103.
And S106, if the difference value between the current statistical time and the last statistical time is within a preset interval, the voltage upper limit duration and the voltage lower limit duration are both increased according to preset values.
In a possible implementation, the preset interval is [57 seconds, 63 seconds ], the preset value is 1 minute, and if the difference between the current statistical time and the last statistical time is within [57 seconds, 63 seconds ], the voltage is increased by 1 minute for both the upper limit duration and the lower limit duration.
It can be understood that only when the difference between the current statistical time and the last statistical time is within the preset interval, the voltage is increased by the time length of the upper limit and the time length of the lower limit, and the voltage is kept unchanged by the time length of the upper limit and the time length of the lower limit in other cases.
S104, calculating the voltage qualification rate of the target voltage from the preset starting time to the current statistical time by using the updated voltage monitoring time.
The voltage monitoring duration, the voltage upper limit duration, the voltage lower limit duration and the voltage qualification rate meet the following formulas:
wherein P is the voltage qualification rate; t (T) 1 For a voltage monitoring period; t (T) 2 The upper limit of the voltage is longer; t (T) 3 For a duration of time that the voltage is lower.
Under the condition that the updated voltage monitoring time length is not zero, substituting the updated voltage monitoring time length, the voltage upper limit time length and the voltage lower limit time length (possibly updated) into the formula, and calculating the voltage qualification rate of the target voltage from the preset starting time to the current statistical time.
Similarly, the voltage threshold out-of-limit ratio P ′ The calculation formula of (2) is as follows:
it should be noted that, if the updated voltage monitoring duration is zero, the calculation of the voltage qualification rate is not performed, and the current statistical time is stored, so as to determine the updating mode of the voltage monitoring duration in the next statistical time.
In order to perform the above method embodiments and corresponding steps in each possible implementation, an implementation of the voltage qualification rate statistics apparatus 100 is given below.
Referring to fig. 4, the voltage qualification rate statistics apparatus 100 includes a reading module 101, a determining module 102, and a processing module 103.

Optionally, the processing module 103 is further configured to increase the voltage duration beyond the upper limit and the voltage duration beyond the lower limit according to the preset values if the difference between the current statistical time and the last statistical time is within the preset interval.
