[China Instrument Network Encyclopedia Knowledge] With the construction of the smart grid, the four-table copying system is being successfully planned. The so-called four meters, that is, water meter, electricity meter, heat meter and gas meter four kinds of meter, but surely most people do not understand why the copy system is completed by the electricity to complete the integration, today Xiaobian with everyone meticulous about the four tables set The truth of copying.
What is a four-sheet set copying four-meter meter is a water meter, electricity meter, hot meter and gas meter, there is a four-table copy of the statement is that a variety of meter through their own acquisition equipment to reach the trunk or platform to collect data back, and finally Convergence to the energy data platform to achieve a four-table copying effect. From a narrow understanding, this method is not a four-table copying method that we want, because it has too many redundant things, and its collection equipment and main station are established separately, although the data all come to the energy data. The public platform can be called "four-table acquisition," but it is not very relevant to the "set" of the four-sheet copy.
There is another way to say that the four-sheet form of copying is to remove all electricity, water, gas, and hot trunk systems, and then establish a public data platform, a general station, to transmit data through their own collection equipment, so that all The energy data collection effect, but this still can not be called "four tables set copy", because the site acquisition equipment installation and maintenance are all their own politics, the data can come back, but the word "set" does not touch.
From the power point of view, we believe that the four-table copy is like this: we can save some acquisition equipment and the construction of the main station, and use the existing collection equipment or main station of an industry as the backbone network to achieve water, Electric, gas, and heat data collection and data aggregation. From the power point of view, the four tables must be copied, the first must have a unified collection equipment; the second is a unified information channel; the third is to have a unified data acquisition and storage platform. These three points are all in place. We think that we can achieve the effect of copying the four tables.
Why is the four-sheet collection copied by electricity to complete the first coverage, electricity has an electricity information collection system, the current coverage of this system by the end of 2014, covering 255 million households; the basic guarantee of each city Each building unit has a collecting device; a guest speaker said that the State Grid only concerns buildings or units. In fact, the vast majority of the State Grid can still complete the acquisition through the community.
The second is the channel. The channel of the power consumption acquisition system is generally divided into a remote communication channel and a local channel. Long-range currently uses stable channels such as GPRS. Others, such as the use of the State Grid’s own fiber-to-the-home network, can achieve higher reliability and can reduce operating costs. During the installation and trial process, Beijing has gradually used the fiber of the State Grid. Replace GPRS. Local channels include communication technologies such as narrow-band carriers, wide-band carriers, and micro-power wireless. At present, at least one data acquisition requirement can be supported once a day, and some provinces have already realized larger data volume services such as remote electricity charges. In fact, the amount of data collected once a day is more than one, and the amount of data is already quite large.
The third is the normative aspect. Like many of the guests, the power industry has a higher degree of completeness than the water and gas industries in terms of specification. For example, the DL/T 645 standard for electric meters and the 1376.X series for acquisition standards also include standards for detection. And so on, the current maturity of these series of standards is high enough to support 255 million electricity consumption information collection systems, and it also has a strong expansion of 28 points.
The fourth is the data platform, which can support a large amount of data. At the same time, the structure is standardized and it is easy to expand the external interface. Using the above four advantages, the use of electricity information collection system to do a four-table copy can achieve a multiplier effect.
At present, the data collection success rate of power consumption information collection systems is as of the end of 2014. According to the statistics of long-distance communication methods, the minimum success rate of real-time wireless public network collection exceeds 96%, and the daily freeze exceeds 98.5%. According to the statistics of local communications, the daily frozen collection success rate of narrow-band carrier, broadband carrier, micro-power wireless, RS485, and GPRS is all above 98%. However, the success rate of collection still needs further improvement.
to sum up
The first is the construction of centralized meter data collection systems for many years, and has accumulated a wealth of technical and implementation experience; the second is the ready-made meter data collection channel, the city has at least covered the building units; the third is only need to replace or add a small amount Acquisition equipment, and active equipment; Fourth, the data platform is mature and stable, easy to expand.
