The 3rd Conference on the Preparation of the Standard for Remote Transcription of Residential Buildings
2019-09-06 19:03:56
[China Instrument Network Instrument Standard] April 16th -17th, coincides with the weekend, all the troops arrived in Chengdu, Sichuan Province to participate in the Ministry of Housing and Construction under the leadership of the "People's Republic of China construction industry industry standard "residential remote meter reading system" (JG / T 162) The standard preparation of the third working meeting.
The first two meetings recalled: The first revision of the standard for residential remote meter reading systems was held
The second meeting of the preparation of the standard for residential remote meter reading system was held
Mr. Lin Runquan, team leader of the Standards Development Group and researcher of the Policy Research Center of the Ministry of Housing and Urban-Rural Development, introduced the work summary of the previous phase of the standard revision and the tasks of the next phase. Mr. Wang Xuewei, deputy head of the Standards Development Group and professor of Beijing University of Chemical Technology chaired the panel discussion on "standard technical specifications and communication protocols". One and a half days later, the focus of the debate was mainly on the uplink communication protocols and test methods. In terms of testing, the basic correspondence with the previous technical conditions, most of the existing terms, not many changes, but the difference in format. The part of the communications protocol is controversial. The communication protocol discussed at the meeting was modified based on DL/T698.41, but many people proposed an object-oriented communication protocol like DLMS, and no consensus has been reached.
Comparing with the previous two standard preparation work conferences, Xiao Bian has combed some different places for your reference:
The third meeting featured guests who were...
The participants in the two previous meetings mainly came from water, electricity, gas, and heat metering companies. This time in addition to leaders from the Ministry of Housing and Urban-Rural Development, the China City Gas Association, and the Henan Provincial and Shaanxi Provincial Construction Standards and Design Offices, Sichuan Energy Development and Reform Commission, It may be the gas field that the contractor Chengdu Qianjia Institute is focusing on. The meeting specially invited many guests of gas companies, such as Sichuan Huayou Group, Sichuan Chuangang Gas, Guiyang Gas (Group), Mianyang Gas (Group), Zhengzhou Huarun Gas. , Chengdu City Gas, Guangyuan Natural Gas, Shanghai Gas Group, Beijing Gas Group, Xinxian County Gas.
During the conference, special guests of Shanghai Gas, Beijing Gas, and Mianyang Gas made technical presentations. Those who are familiar with the meter reading technology and applications in the gas industry know that Shanghai Gas and Beijing Gas are examples that we all have in mind.
Looking back at the second conference handbook on March 5th, there are paragraphs and small editions that are especially impressive: currently the manufacturers participating in the preparation of standards are limited to the production companies of water, heat, electricity, gas and other watches, water companies, gas companies, Heating companies, etc., have not participated yet, and the team hopes that these companies will participate in the preparation of standards. Can't help Xiao Bian thinking about it, is it that the first batch of utility companies that will be absorbed by the “Remote Remote Meter Reading System†will come from gas companies? ? ?
Do you know who 39 member groups are?
The preparation of the standard revision consultation draft has been added...
In addition to the amendments and deletions of individual texts, we have read the draft specification for the draft revision of the draft standard that we saw at the second working meeting - the standard of the remote meter reading system and the "Internet" action plan and the "Smart City". There are the following updates:
Increase 1:
Third, the core content of the standard and the core technical content of the physical boundary standards are two points, the first is that the real-time consumption of water, electricity, gas, heat and other data generated in a reliable and secure transmission, the second is the proposed technology for the above data transmission methods Requirements and corresponding system testing methods. In other words, the standard is to serve the energy measurement, smart communities, and green buildings of the public utilities at the technical level to meet the energy consumption monitoring, water saving, material saving, energy saving, land saving, and environmental protection of green buildings. Environmental protection" needs.
In other words, the physical boundary of this standard is from the metering requirements (external features) of the remote meter to the computer master station.
Increase 2:
In addition to the previous “Document Two: General Rules†and “Document Three: Proceduresâ€, this meeting added “Document No. 4: Measuring Equipment Communication System†written by Xing Weihua. Although there was no discussion at the scene, Xiao Bian also summarized the basics. Framework for everyone to know:
I. Overview With the development of Internet of Things technology and the need for smart city construction, the traditional communication methods of measuring equipment and the definition of data transmission equipment have been unable to adapt to the needs of the new situation. They should follow the principle of “advancing with the times†and participating in the country. The “supply side†reform and the “shared economy†call have been formulated. In order to realize the national strategy of “collection of four formsâ€, this standard has been formulated.
Second, the overall structure of the third, the definition and description Fourth, communication identification code 1, equipment communication identification code code 2, equipment communication identification code associated encryption 3, key data encryption 4, authorized measurement equipment type interactive verification identification V. parameter code table 4 Control Status Code Table Table 5 Unit Code Table Table 6 Time Data Code Table Table 7 Upstream Data Code Table Table 8 Downstream Command Code Table VI, Communication Protocol 1, Data Packet 2, Startup Mode 3, Transmission Control 4, Data Encryption 5, Gateway Transparent transmission of data 7.

Three meetings, participants’ feelings
- In the event of disagreement during the discussion of specific details, the leader will reiterate certain points of view and will be able to resolve the differences. For example, many people have continuously strengthened the functional requirements of the meter and are determined to be beyond the standard discussion boundary.
- Some old comrades made a lot of sense. For example, Wu Desheng, an old dean of the Beijing Institute of Architectural Design and Retirement at the second working conference, said at the crucial moment, "The wrong can't be, and the answer is not all there is". It set the tone for the standard discussion meeting, but many people did not understand it during the discussion.
- Most people do not understand the level relationship of standard preparation. As an industry standard, it is not allowed to quote corporate standards. It should be more flexible than corporate standards, and technical indicators need to be loosened. Many people in the field of electric meters think that they can directly use the standard of the State Grid.
- The standards of the Ministry of Housing and Urban-Rural Development involve a wide range of standards. It is the standard for guiding and inspecting the design and construction of buildings. This was raised in several meetings as a customer. In the standard discussion, the person standing in this position and seeing the problem is Less.
- In addition to water, electricity, gas, and heat, instruments such as thermometers and pressure gauges have also been incorporated. Actually, they have surpassed the scope of use of the four-state copy of the State Grid. Standards can only be more relaxed. Can take the basic framework, allowing companies to freely play within the framework.
- The gap in the development level of the industry is too great. In the discussion, when it comes to some details, there is a feeling of talking with chickens and ducks, which also makes it very difficult to revise this standard.
- For the "should/should not", "suitable/unsuitable", and "may/do not" scales, most of the discussants are still standing in their own industry. Such a long-span standard, the "ought" word needs to be minimized Use may be more appropriate.
- In order to meet the national policy, the standard revision adds some unrealistic terms, such as the Internet, information security, etc. Although it feels very large, it is not grounded, and some of the clauses also use mandatory " Should be the word. For example, many property-based acquisition systems simply do not need these, and they should not actually be based on standards.
- Internet of Things thinking, using the intermediate process as a communication channel, and enterprises only managing front-end products and back-end data, this is an inevitable direction of development. When the technology is mature, there is no maintenance work such as the middle collector concentrator, the price is reasonable, and the grid will be used!
