Abstract

The present invention relates to a method for reading load profile (LP) data preventing a duplicate read and an omission of data which includes a collection stage which collects LP data stored in accordance with a first distinct address by measuring a read server through a watt-hour meter; a judging stage which judges whether the read server corresponds to a distinct address following the first and a second distinct addresses; and a saving stage which saves LP data collected by the read server. The second distinct address corresponds to the LP data which is saved the most recently in the read server. According to the present invention, LP data measured through the watt-hour meter are stored in different distinct addresses, and the distinct address with the measured LP data and the distinct address with an ultimately collected LP data are compared so that a duplicate read of the collected LP data is prevented.

Description

[0001] METHOD FOR READING LP DATA PREVENTIVE REPORT [0002] BACKGROUND OF THE INVENTION [0003]

More particularly, the present invention relates to a method and apparatus for detecting duplicate data and preventing a drop in data from being duplicated by checking data already mapped at the time of meter reading of LP (Load Profile) data, The present invention relates to a data duplication check method and a LP data inspection method for preventing a drop in server processing speed due to load weighting and redundant data sorting.

Recently, AMI (Advanced Metering Infrastructure) and smart grid construction are vital for efficient power use, intelligent power grid operation and demand management.

The AMI and Smart Grid aim at active demand management based on the user (customer) rather than the power management method based on the past supplier (electric power company). For this purpose, real-time acquisition of the electricity consumption used by the customer, Two-way communication capability is needed to provide information at the same time.

In addition, it is necessary to introduce a rate plan that can trigger a response to customer demand, such as a real time price or a critical peak pricing.

In order to satisfy these requirements, a watt-hour meter capable of generating and storing LP (Load Profile) data indicating the amount of electrical and mechanical energy consumed by the customer and a meter reading device capable of collecting LP data of the watt- Technology is required.

Conventional watt-hour meters typically measure and store LP data in 15-minute to 1-hour increments, and the meter reading server collects LP data from the watt-hour meter in 15-minute to 1-hour increments.

The existing watt-hour meter stores the measured LP data as First Input First Output, and the number of LP data transmitted to the meter reading server or DCU (hereinafter referred to as a meter reading server) through the watt-hour meter is measured every measurement period 48 for the low-pressure watt-hour meter, and 96 for the high-pressure watt-hour meter. Therefore, only the new data is stored in the DB through the process of selecting and removing redundant data already obtained from the LP data acquired by the server.

That is, in the existing weighing method, unnecessary LP data that have already been acquired is acquired redundantly in order to acquire the actual necessary data, and the process of selecting and eliminating the redundant data is performed, There is a problem in that the server processing speed is lowered.

In addition, since the data is called based on the past address of a certain time before the present time, data omission due to the address change occurs when the data collection period is exceeded due to communication failure, etc. In this case, .

This conventional weighing method can cause distortion of customer's power consumption due to missing LP data at the time of introducing a real-time charge plan or a peak charge plan in the future, and may reduce the efficiency and reliability in the control of demand management and power loss at all times. There was a need for a new weighing method to prevent omissions and prevent duplication.

As a prior art related to the present invention, there is Korean Patent Publication No. 10-2010-0061199 (published on June, 2010, entitled Active Echo Driving System).

The present invention is characterized in that newly measured LP data is stored at a unique address whose LP value measured by the watt-hour meter is increased by a reference value from a unique address where previously measured LP data is stored.

If the first unique address does not correspond to the next unique address of the second unique address, the metering server transmits the unique address from the next unique address of the second unique address to the previous unique address of the first unique address And collects the LP data stored corresponding to the address.

According to another aspect of the present invention, there is provided a method for checking data duplication and preventing omission from occurring, comprising the steps of: receiving a first unique address of a meter reading server storing load profile data measured through a watt hour meter; Determining whether the first unique address corresponds to a next unique address of the second unique address; Collecting the LP data stored in correspondence with the first unique address when the first unique address corresponds to the next unique address of the second unique address; And storing the LP data collected by the meter reading server, wherein the second unique address corresponds to the LP data most recently stored in the meter reading server.

The present invention is characterized in that newly measured LP data is stored at a unique address whose LP value measured by the watt-hour meter is increased by a reference value from a unique address where previously measured LP data is stored.

If the first unique address does not correspond to the next unique address of the second unique address, the metering server corresponds to each unique address from the next unique address to the first unique address of the second unique address And collects the stored LP data.

That is, in this embodiment, the LP data is stored in the address where the unique address is increased by the reference value every time the new LP data is measured, and the period for measuring the LP data and the reference value indicating the increased amount of the unique address can be freely set .

Except in exceptional cases, the meter reading server 20 collects the LP data measured at the same period as the period of measuring the LP data in the watt-hour meter 10, so that when the LP data is measured through the watt- Collected LP data first.

Next, the meter reading server 20 determines whether the first unique address corresponds to the next unique address of the second unique address (S20). In this case, the second unique address means the unique address of the watt-hour meter 10 corresponding to the LP data previously stored in the meter reading server 20 most recently.

This determination is made to check if there is LP data that can not be collected and stored by the meter reading server 20 among the LP data measured through the watt-hour meter 10 due to an exceptional situation such as a communication failure.

In this embodiment, since the measured LP data is stored in the next unique address of the unique address where the previously measured LP data is stored, the first unique address is the next unique address of the second unique address, It means that there is one cycle difference.

Therefore, if the second unique address, which is the unique address of the watt-hour meter 10 corresponding to the LP data previously stored in the meter reading server 20 most recently, corresponds to the previous unique address of the first unique address, The LP data measured before the measured LP data is collected and stored in the meter reading server 20.

On the other hand, if the first unique address does not correspond to the next unique address of the second unique address, the meter reading server 20 corresponds to each unique address from the next unique address of the second unique address to the previous unique address of the first unique address The stored LP data is collected from the watt hour meter 10 (S22).

The fact that the first unique address does not correspond to the next unique address of the second unique address means that the meter server 20 can not collect and store a part of the LP data measured through the watt-hour meter 10 due to a communication failure or the like.

Accordingly, since the collection of the LP data stored up to the second unique address is normally completed, the LP data is collected from the next unique address (second unique address + reference value) of the second unique address, and the LP data stored corresponding to the first unique address LP data stored corresponding to each unique address up to the previous unique address (first unique address-reference value) of the first unique address is collected because it is collected in step S10 described above.

Next, the meter reading server 20 stores the collected LP data (S30).

In particular, in this embodiment, since the LP data collected by the meter server 20 depends on whether the first unique address is the next unique address of the second unique address, the first unique address is the next unique address of the second unique address And if the first unique address does not correspond to the next unique address of the second unique address, the second unique address of the first unique address is stored from the next unique address to the previous unique address of the first unique address And further stores the collected LP data.

First, a meter reading server 20 reads LP (Load Profile) data is stored (S110). In this case, the first unique address means a unique address where the LP data measured most recently through the watt-hour meter 10 is stored.

In this embodiment, newly measured LP data is stored in the next unique address of the unique address where the previously measured LP data is stored when the LP data is measured through the watt-hour meter 10, and the next unique address is a reference value ≪ / RTI >

That is, in this embodiment, the LP data is stored in the address where the unique address is increased by the reference value every time the new LP data is measured, and the period for measuring the LP data and the reference value indicating the increased amount of the unique address can be freely set .

Then, the meter reading server 20 determines whether the first unique address corresponds to the next unique address of the second unique address (S120). In this case, the second unique address means the unique address of the watt-hour meter 10 corresponding to the LP data previously stored in the meter reading server 20 most recently.

This determination is made to confirm that all of the previously measured LP data have been collected and stored before collecting the most recently measured LP data.

In this embodiment, since the newly measured LP data is stored in the next unique address of the unique address where the previously measured LP data is stored, the first unique address is the next unique address of the second unique address, Is one cycle difference.

Therefore, if the second unique address, which is the unique address of the watt-hour meter 10 corresponding to the LP data previously stored in the meter reading server 20 most recently, is the previous unique address of the first unique address, LP data previously measured in addition to the LP data collected by the meter reading server 20 is collected and stored.

Accordingly, if the first unique address corresponds to the next unique address of the second unique address, the meter reading server 20 collects LP data stored corresponding to the first unique address from the watt-hour meter 10 (S130).

That is, when the first unique address corresponds to the next unique address of the second unique address, only the LP data measured most recently through the watt-hour meter 10 can be collected, thereby collecting only the LP data necessary without duplication.

On the other hand, if the first unique address does not correspond to the next unique address of the second unique address, the meter reading server 20 stores the LP data stored corresponding to each unique address from the next unique address to the first unique address (S122).

The fact that the first unique address does not correspond to the next unique address of the second unique address means that there is another unique address after the second unique address, so that a part of the LP data measured through the watt- 20). ≪ / RTI >

Accordingly, the meter reading server 20 obtains the first unique address (the second unique address + reference value) of the most recently measured LP data from the next unique address (second unique address + reference value) And stores the LP data corresponding to each unique address.

Next, the meter reading server 20 stores the collected LP data (S140).

In particular, in this embodiment, since the LP data collected by the meter server 20 depends on whether the first unique address is the next unique address of the second unique address, the first unique address is the next unique address of the second unique address And if the first unique address does not correspond to the next unique address of the second unique address, it stores the LP data corresponding to the first unique address, And collects and stores the LP data stored corresponding to the address.

According to the present embodiment, by storing the LP data measured through the watt-hour meter 10 in different unique addresses, comparing the unique address where the measured LP data is stored and the unique address where the LP data finally collected is stored, It is possible to prevent duplicate inspection of one LP data.

In addition, this embodiment can prevent LP data from being omitted by collecting LP data stored in a unique address that is missing through comparison of unique addresses.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, I will understand. Accordingly, the true scope of the present invention should be determined by the following claims.
