Description
Technical field
The present invention relates to the accurate statistical processing methods of acquisition tables code value in a kind of metering system.
Background technology
As shown in figure 1, the data communication flow process of industrial energy metering system includes：Industrial energy metering system software deployment
In the information centre of industrial undertaking or the computer server at energy conservation center, by sides such as optical fiber, wireless, Ethernets
Formula passes through again with the power measurement acquisition gateway communication for being distributed in each scene and energy instrument room, each power measurement acquisition gateway
Fieldbus and energy meter communication nearby.The protocol conversion for so being communicated by two-stage, from the energy meter to energy measurement
Acquisition gateway, then to Energy Consumed Statistic System software, every certain time interval, system can gather the table code of industrial instrument meter
Value (numerical value of gauge table) is stored in historical data base, based on initial data, statistical procedure can process these data, according to when
Between and table code calculating intervals, the such as continuous data within hour, day, the moon, week, season, year.
Various industrial energy meters, such as ammeter, water meter, gas meter, hotlist (heat meter), as energy usage is constantly tired out
Long-pending, under normal circumstances it gathers the numerical characteristics of the table code data come up or constantly increases over time, or due to
Scene keeps constant without consumption.Quantitative statisticses program will calculate the energy measurement consumption in interval of time, process side
Method is：The table code value and the table code value of end time of time started in this period are obtained, then by the table code value of end time
The table code value of time started is deducted, this difference should be under normal circumstances the data more than or equal to zero, as this time
Energy measurement volume value, as shown in Figure 2.
But in the industrial environment of reality, the table code data come up of energy meter collection can undergo mutation the feelings of zero
Condition, is mainly based upon following several reasons：(1) table code has arrived at the full code value of the maximum number of digits of meter, automatically generates reversion,
Table code is zeroed；(2) artificial situation about resetting, it may be possible to the clearing of handing over to the next shift between teams and groups, or scene meter failure changed；
(3) disconnection fault of communication failure or energy resource collecting gateway, during this period of time makes metering system software to collect table
Code data, do return-to-zero.
If statistical procedure is needing to be there occurs in the time period to be processed the situation of above-mentioned mutation zero data, according to routine
There will be two kinds of situations for processing method：The first situation as shown in figure 3, the reversion of above-mentioned table code and it is artificial reset in the case of,
The table code of end time period is to restart to increase from after zero, deducts the table code of time started, obtains a result or is negative
Count, or end time table code has been risen to than start-up schedule code greatly, is positive number after subtracting each other, but this is to have measured meter
Increase again after table code zero and used with the energy measurement of moment to statistics this period of end time of segment table code-phase etc. when starting
Amount, and increase again after zero and this period at moment of segment table code-phase etc. when starting from the statistics time started to meter table code
But without statistical metering, the result for so drawing is the numerical value less than actual energy usage for metering；Another kind of situation such as Fig. 4 institutes
Show, in the case of communication failure or energy resource collecting gateway power-off, in failure, table code is always zero, if at the end of statistics
Between failure it is recovered, table code is back to normal, and so deducting start-up schedule code with end time table code can obtain normal value, but
Be likely to until the table code of statistical time range end time is still zero, deduct the table code of period start time, obtain a result for
Negative.
In existing industrial energy measuring software for above-mentioned zero mutation wrong data cannot normal process, occur
The statistical data of mistake, its processing method afterwards is input in systems table code reversion log often by manual record
Code, the system changed meter log code, reset meter log code and then trigger the data base of statistical updating again of measuring software
Evaluation, or direct labor's amendment wrong data.But as industrial undertaking increasingly payes attention to energy management work, management is got over
More to refine, constantly strengthen energy meter and install and gage work, level of factory, workshop level critical point energy meter are covered with substantially
Deployment, conditional industrial undertaking also covers the deployment of the higher device level energy meter of energy consumption.So industrial energy metering
The data of system energy meter to be processed are also just more and more, for recurrent meter zero mutation wrong data, energy
Source statistical metering personnel often can only artificial correction be used to settling accounts factory, the accidental data of workshop level critical point energy meter, and for
The accidental data of more device level energy meters, then cannot one by one change correction by artificial method, thus cannot and
When obtain accurate energy usage, can to industrial undertaking become more meticulous energy conservation and Energy Efficiency Analysis bring error.
The content of the invention

Specific embodiment
Below in conjunction with the accompanying drawings technical solution of the present invention is described in further detail with specific embodiment, so that ability
The technical staff in domain can be better understood from the present invention and can be practiced, but illustrated embodiment is not as the limit to the present invention
It is fixed.
To the accurate statistical processing methods of acquisition tables code value in a kind of metering system, as described in Figure 6, comprise the steps：
Step 1, time interval T that system calling acquisition instrument table code data are set, T≤instrument minimum statistics time interval
1/10.The sample frequency of higher energy meter table code is set in industrial energy metering system, between the time of its sampling
Every to be less than the 1/10 of minimum statistics time interval, the minimum energy measurement statistical unit that such as certain meter is required is hour, then its
The sampling time interval of table code is 6 minutes or less, so in arbitrary hour timing statisticses section, can there is at least 10 tables
Code record is transfused to the investigation of statistical disposition program.
Step 2, the head and the tail time for being input into the period to be counted, according to statistical time range, according to acquisition time order this when is obtained
All original table code value sequences in section.According to statistical time range initial time, obtain all table code collection values in the period and
Acquisition time, according to collection value time sequencing, will be divided into the less statistical time range of sample period lengths in big statistical time range.
It is preferred that, outside obtaining comprising all table codes records in this statistical time range, increase to previous statistical time range and to
The acquisition of the table code record of latter statistical time range.When so obtaining previous statistical time range, this period, latter statistics in advance
Section all original table code value sequence datas in totally 3 sections of periods, during in case the statistical time range head and the tail time running into zero accidental data
Increase data analysiss to be judged.
Step 3, the table code initial value for obtaining the period to be counted.
Step 4, current table code value is compared with next table code value.Table code value compares before and after this step is carried out two-by-two,
When rear timetable code value (referred to as then be worth) is more than front timetable code value (value before referred to as), it is believed that current front value effectively, then after
It is continuous to investigate backward；When value is less than front value after running into, it is believed that run into mutation zero.
Step 5, judge that whether current table code value is last table code value of period to be counted, if yes then enter step
9, if not then into step 6.
If step 6, current table code value effectively, then continue to investigate backward less than next table code value, current table code value, its
It is middle to make the current table code value that current next table code value is next comparison loop, into step 4, otherwise, judge to occur in that
The situation of mutation zero, into step 7.
Step 7, by mutation before, time period of not undergoing mutation corresponding subsegment table code carry out temporary statistics, record to should
The temporary statistics result of subsegment, into step 8, judges the type of mutation zero.
It should be noted that, due to the period to be counted be mutated zero number of times it is unknowable, therefore the period to be counted be mutated zero
Situation divide into several subsegments, time period of each subsegment correspondence single mutation or the time period do not undergone mutation, its
In time period for not undergoing mutation, according to conventional statistical method, the table code value of end time in the time period is deducted into beginning
The table code value of time is used as temporary statistics result.
If step 8, the type for belonging to the reversion of table code or artificial clearing, by the corresponding table code initial value of the mutation time section
0 is set to, into step 4；If belonging to the type of communication failure, reject it is all less than mutation before last table code value number
Value, is set to the last table code value before being mutated, into step 4 by the corresponding table code initial value of the mutation time section；
Step 9, cumulative all temporary statistics results, along with currency deducts this subsegment table code initial value, export and wait to unite
The variable of timing section.
How normal artificial situation about resetting with table code reversion or improper communication failure is accurately judged, for system
Different processing paths are had in meter routine processes, very big difference is brought.Specifically determination methods are：
A last the table code value before zero) is recorded, continuation gathers backward follow-up table code value, until collecting weight
Newly start N number of table code value of continuous growth；
B) N number of table code value is averaged, and with step A) record zero before last table code value compared with；
C) if last the table code value before zero is judged as belonging to the reversion of table code more than the meansigma methodss of N number of table code value
Or the artificial type for resetting, otherwise, it is judged as belonging to the type of communication failure, it is zero that table code misses collection, by these communication failures
Data reject after with zero before data merges, then unify processed.
As it can be seen in figures 5 and 6, it is preferred that, N=3 takes the determination methods of the meansigma methodss of continuous 3 table codes, is to prevent communication event
After barrier recovers, when continuous data just starts to upload, the data of generation change up and down shake, allow the situation of program erroneous judgement.
There is mutation zero in table code near the close time started and end time of this statistical time range, then expand examination
Scope, therefore, can obtain according to acquisition time order：
There is mutation zero when the time started of this period, then according to the original table code value of the previous statistical time range for obtaining
To judge to be mutated the type of zero；
There is mutation zero when the end time of this period, then according to the original table code value of the latter statistical time range for obtaining
To judge to be mutated the type of zero.
Last table code value in the complete statistical time range of routine processes, by by each subsegment metering split in the case of mutation zero
Intermediate result added up (if the situation of zero is not mutated whole statistical time range be 1 whole period), finally draw
Metered amount value in this statistical time range.
Compared with prior art, change and only take the method that statistical time range tail head table code-phases subtract, but take in measurement period
Multiple table code values increase statistical samples carries out comparing two-by-two for before and after table code value, so can, level Four a large amount of three with automatic decision (set
Standby level) industrial instrument metering data it is daily artificial clearing for several times and the reversion of table code, the situation of communication failure all may occur,
So as to take different statistical disposition strategies.On the one hand the consumption statistical accuracy that industrial instrument is measured is ensure that, on the other hand
Numerous and diverse manual maintenance and the work for screening data are changed to into automated procedures process, enterprise measurement management and energy system is improve
Meter work efficiency, improves the degree of accuracy of statistics.
The preferred embodiments of the present invention are these are only, the scope of the claims of the present invention is not thereby limited, it is every using this
Equivalent structure or equivalent flow conversion that bright description and accompanying drawing content are made, or directly or indirectly it is used in other correlations
Technical field, be included within the scope of the present invention.
