Comparing the development of the four forms of copying in the previous four tables, there were corresponding developments in the four-table copy-taking system in each area in June and July. Many regions not only actively promote their work, but also have many bright spots on the technical level.
[Highlight 1] Shanghai's unification of industry standards One notable thing is that Shanghai first proposed the concept of establishing a unified smart watch technology standard and a unified protocol standard for remote transmission! Remember to publish "When those anecdotes 1" were published, there was a tiger shoe message: "Compatible with different types of metering instruments with different protocols, it's easy to say, it's not easy to do it, and the device also supports the transmission of data to multiple destinations ip Subdivision of data transmission is not as simple as imagined.†This time, Shanghai’s practice of setting a unified industry standard is not a big deal. After the standards are unified, the watch manufacturer can mass produce. The work of protocol conversion will also be greatly simplified. It is reported that Shanghai will increase the "three forms of reading" promotion efforts, and strive to complete the first batch of 100,000 households in the year, the installation of electricity copying and construction!
[Highlights 2] Four-table compilation copy cost allocation Four-sheet collection There is an important premise: the water meter and the gas meter must first realize intelligent transformation, which involves the problem of infrastructure reform costs. Zhengzhou City has a preliminary plan for this issue. Adding collection equipment, this part of the cost by the power company responsible for, and the existing mechanical watches, non-intelligent watches are replaced with smart watches, you need to be responsible for the water company, gas company. Of course, this involves the replacement of the meter. It requires the communication and cooperation among the enterprises, and it also needs the support and guidance of the policy.
[Highlight 3] Four Tables Sharing Data Sharing Platform Jiangsu Taizhou Power Supply Company's innovative construction of an inter-industry energy operation dynamic data integration platform consisting of a main station platform, concentrator, dual-mode collector, meter, and meter , to achieve the electric water gas (heat) data push sharing. This is a new initiative of the Jiangsu Provincial Power Corporation's innovative “three-table collection†intelligent management model, which also provides a new direction for solving the data sharing problem of the four tables. Huangshi Power Supply Company, on the other hand, pushes the data collected by the main station to the water, gas, and heat companies by means of a copy or interface.
[Highlight 4] The grid company assisted the water, gas, and heat companies to transform Guodong Haidong Power Supply Co., Ltd. to assist the water company in reforming the water meter during the project development process, formulate a smart water meter collection plan, and maintain the power consumption information collection remote communication channel. The integration of water meter and meter collection lays the technical foundation. In the short-term, this kind of cooperation is similar to the development of big brothers and younger brothers and sisters. It is in-depth thinking that cross-industry cooperation may be able to create new sparks in the development of electricity, water, gas and heat industries.
There are industry restrictions on copying the four forms, but the trend is unstoppable Currently Yuncheng Power Supply Company, Haidong Power Supply Company, Qinshui County Power Supply Company, Sichuan Electric Power Company, Xiangyang Power Supply Company, Hubei Provincial Power Company, Qinghai Electric Power Company, Yakeshi Power Supply Company, Changchun Power Supply Company, Boltala Mongolia Autonomous Prefecture Power Supply Company, Zhangjiajie Power Supply Company, Changzhi City Power Supply Department, Erguna City Power Supply Company, Zaozhuang Power Supply Company, Genhe City Power Supply Company, Hubei Provincial Power Company, Deyang Power Supply Company, Shandong Zhangqiu City Power Supply Company, Longnan Power Supply Company , State Grid Jiangdu Power Supply Company, Zhumadian Power Supply Company, Jincheng Power Supply Company, Lanzhou Power Supply Company, Huangyan Power Supply Company, Baoji Power Supply Company, Huangshi Power Supply Company, Urumqi Power Supply Company, Huinong District Power Supply Company, Jiangsu Taizhou Power Supply Company, etc. Collecting and copying fields have been successfully piloted.
Can the size of the name be felt just by looking at the number of names? Shanghai, Henan, Sichuan, Hubei, Jiangsu, Shandong, and other regions have entered the deployment phase of the large-scale promotion of the copying of the four tables. For the four-table copying, although there are still industry restrictions, the trend is unstoppable. In the promotion process, it will inevitably cause impact on the original business of traditional electricity, water, gas, and heat meter manufacturers. It is also a challenge to the development of the business. At the same time, in the face of customers in four industries, how should traditional metering companies break through the transition? Thinking now, it's not too late.
At the end of the article, Xiao Bian summarizes the technical aspects of the process of making copies in a few sentences and four tables.
On the technical side, it seems that everyone has a certain degree of tacit agreement, and many regions adopt the "protocol converter" + "concentrator" approach. The data of water, gas, and heat meter is transmitted to the protocol converter. Then, the protocol converter transfers the data to the concentrator through wired or wireless methods, and then transmits the data to the back office of the power company in a timely manner to implement a four-table set. copy. This method solves the problem of copying four tables from the technical level, and is a major highlight of technological development.
The State Grid Hetian power supply company pilot innovation using two kinds of technical solutions also gives everyone more choices. In the pilot, part of the micropower wireless smart water meter communicates with the concentrator, and part of it uses a communication interface converter. The converter uplink and concentrator use carrier communication, and the converter downlink and smart water meter use M-BUS communication. The acquisition master station pushes data to water, gas, and heat companies by means of a copy or interface.
Wuhan Power Supply Co., Ltd. installed a “four-in-one†interface converter under the electricity meter, which was directly transmitted by the converter to a unified information collection system. According to reports, the cost of each system is about 100 yuan. It seems that the cost is not very high, and it is not reliable enough in terms of stability, etc. This will also be observed later.

Four tables set copying construction ranks increasingly large and gradually break through technical barriers
[China Instrument Network Instrument Industry] today Xiao Bian also took two months of the four tables to read the development of the situation. In July and July, the State Grid Jiayuguan, Jiuquan Power Supply Company, and Zhejiang Yongkang Power Supply Company joined the ranks of four-sheet copy-editing and Haidong Power Supply Company, Yakeshi Power Supply Company, Weinan Power Supply Company, and Xing'an Power Supply Company. They also received strong support from the local government one after another.
