The present embodiment gathers transmission technology and communication, low pressure number with reference to the low pressure data that power system is commonly used at present
According to principle of the concentrator in combination with low-voltage carrier communication technology, low-voltage customer ammeter first is all intelligent meter, supports that data are passed
Transmission function, can be the single-phase smart meter with low-voltage carrier communication ability, or 485 common intelligence communication tables, as long as
Possesses the link of communication, intelligent meter is led to by communication modes such as low pressure carrier wave or 485 with low pressure data concentrator
Letter, the function of data concentrator is exactly the data for gathering low-voltage customer ammeter, and communication mode can be low-voltage carrier communication and 485
Communication, the combination of various equipment in the present embodiment can rapidly and accurately collect the data of low-voltage customer, which includes low
Electricity consumption information about power, the real-time voltage of user power utilization, live wire electric current, the neutral line current of pressure user, uncap record, history of history is stopped
Upper power information, power factor (PF) etc..
The data acquisition process unit not only has the function of communicating with data concentrator, while also have being used with low pressure
The function of family ammeter communication, can obtain number order and data that low pressure data concentrator is not supported, while in the mistake for using
It is also convenient in journey.
The presence states monitoring and display unit can select various displays, for showing to low pressure data collection
Situation counts and arranges some corresponding messaging parameters.
The present embodiment have it is local upload and wireless upload function, user can be according to actual conditions reasonable employment, locally
Upload and realize that wireless upload is realized by wireless communication unit, the model of the wireless communication unit by the local interface that uploads
Optional HM-TRLR-S, ultra-small volume, surface-mount type design, convenient embedded, LoRa technology spread spectrum transmissions, communication distance is remote, resists dry
Strong, support more modulation pattern is disturbed, facilitates networking to use.
The course of work and principle of the present invention is as follows：
First, the data acquisition process unit in the present embodiment is connected with data concentrator, obtains current in data concentrator
The ledger management information in platform area, while contrasting with the data in SG186 systems, the information in authority data concentrator.
Secondly, data acquisition process unit control data concentrator transparent data, with obtain low-voltage customer ammeter electricity,
Real-time voltage, live wire electric current, neutral line current, uncap record, history of history stops the information such as upper power information, power factor (PF).
Finally, the data for data acquisition process unit being obtained import the background computer for being loaded with analysis software, by fire
Line current and neutral line current contrast, zero degree user long-time are monitored, record etc. of uncapping judges, draws the suspicious stealing when foreground partition
User, while be analyzed with the data in SG186 systems, draw when foreground partition have table without user data and have family without
Table data, while contrasting with the data in the SG186 systems in the platform area that is connected, show that user's table loads in mixture the data of misloading.
The present invention is obtained when the information of all intelligent electric meters under foreground partition by concentrator, under forming live actual table area
Low-voltage customer intelligent meter archives.Can be by low-voltage customer electric energy meter archive information under instrument Zhong Tai areas and marketing application system platform
Low-voltage customer archives are contrasted under area, find out otherness, realize that live archives are examined to platform area intelligent meter archives.Obtain
The voltage and current data of each low-voltage customer intelligent meter, through the collection analysis of certain hour, draw the load curve of user.Obtain
The voltage x current data of Qu Tai areas summary table, and the user power utilization Data Comparison for obtaining, analysis both difference, draw stealing or
The situation of ammeter misloading.The record of uncapping of low-voltage customer ammeter is obtained, is preserved and is analyzed, uncapped record by checking analysis, can
Draw whether there are the behaviors such as stealing to occur.Obtain live wire, the neutral line current of low-voltage customer table, it was therefore concluded that, inconsistent data
Or the user data that long-term electric current is zero is exported in the form of document, and stealing conclusion is drawn by analysis.
Additionally, the present invention also realizes the automatic search of low-voltage intelligent table under platform area, obtains automatically, achieves automatically, with SG186
Data message in system is contrasted, and realization is examined low-voltage intelligent table files on each of customers, is capable of achieving to marketing system intelligence
The combing of table user power utilization information and make an inventory just mistake archives（There is table without family, have family without table and files on each of customers misplaced platform area）'s
Cleaning.It is 1 pair of N mode to change conventional platform area machine account and verify with 1 couple 1 for looking into stealing.Revolutionize and extensively cast net originally, one by one
The tactics of human sea pattern looked into, is changed to by way of instrument power line carrier, accomplishes that batch is concentrated and verifies, and saves a large amount of people
Power material resources.Realize user's intelligent electric meter voltage, electric current, the curve comparison of load simultaneously to monitor, look into three functions of stealing in batches,
Data can mutually be provided between three functions to support and verify.It is easy to use, can Site Detection field assay, realize stealing use
Being accurately positioned for family, it is live to investigate and prosecute.
Especially because being the intelligent electric meter information under the carrier wave platform collection table area by data concentrator, the present invention exists
Any point is disposably accessed in platform area, you can the whole platform area of generaI investigation, it is to avoid multiple opening electricity box, is greatly reduced and electrical equipment
Frequency of exposure, carry out insulation measures during execute-in-place on request, you can substantially reduce the risk of electric shock, and then prevent to access inspection
Survey the electric shock accidents brought when instrument is detected.
The present invention ensures first that power supply is complete, is using suitable for all users of low-voltage platform area intelligent metering when using
In the case that low pressure data concentrator is as data forwarding, data acquisition process unit should be connected with data concentrator
Come, obtain the data of low-voltage customer, in the case where data concentrator is not used as data forwarding, obtained using data concentrator
Take the table information of low-voltage platform area user, it is also possible to which acquisition low pressure data is carried out according to difference in functionality demand.
Compatibility different manufacturers of the invention, the data concentrator of different model, test unit can be by legacy data concentrator chain
It is connected on data acquisition process unit module, and without the need for newly purchasing instrument, it is possible to complete collection and the place of a series of field datas
Reason, improvement cost is greatly reduced.Because original test apparatus can be adopted, it is ensured that current experimental data ratio vertical with historical test data
Precision of analysis, in the case where stealing pattern is looked into, if monitoring that a user has electricity filching behavior, carries out handing in the electricity charge retroactively to it
And the measure such as punishment, economic benefit is particularly considerable.
Install now and survey in low pressure entirely, simple, convenient, safety, equipment directly calls the real time data for surveying user's table together, data
Accuracy is high, registration, and data import daemon software analysis by local device, it is impossible to changed by bad user, security
It is high.
