[China Instrument Network Instrument Industry] "Four Tables Copy" means that the data of electricity meters, water meters, natural gas meters, and hot meters is reflected in the meter collection system. It is also called "four tables." The collection and application of "Four Tables" proposed and promoted by the National Development and Reform Commission and the National Energy Administration, relying on the experience and technology of power gathering, using the extensive coverage of power collection terminals, and achieving electricity and water in existing collection platforms. The public utilities such as gas, heat, and heat are integrated and remotely collected to increase the level of government public services, reduce duplication of investment in public utilities infrastructure, reduce the overall operating غير مجاز مي باشدts of public utilities, and build a conservation-minded society. It is rumored that Sanchuan Wisdom is involved in the above project. What company is responsible for the business?
Q: Are you involved in the "Four Sheets Copying" project?
Sanchuan Wisdom: Yes, investors have asked Sanchuan wisdom on the interactive platform of the panorama network. Whether the company is involved in the “four-sheet copying” project. Sanchuan Wisdom responded that at present, the “four-in-one” transformation project has been launched in multiple cities. In order to comply with the new situation, the company actively conducted in-depth exchanges and discussions with related companies such as the Jiangxi Provincial Electric Power Company of the State Grid and reached cooperation. Intentions, it is planned to implement the “four-in-one” transformation of 80,000 smart water meters in Yingtan City and create a quality model project, which will be gradually promoted nationwide. The National Grid covers the entire country and urban areas. With the advancement of the “Four-in-one” project, it will enable the company to seize opportunities, effectively promote the promotion of the company’s smart water meters, and improve company performance.
With the popularity of the Internet of Things, more and more attention has been paid to the copying of the four tables. There have been many typical cases of copying across the country, but at the same time it also brings us thoughts.
I. Collecting copies of current status The four forms of water, electricity, gas, and heat utilities belong to different units, and different industries have different instrument standards. Among them, the most critical standard is the 2004 release of the "CJ/T188-2004 Household Metering Data Transfer Technical Specifications" published by the Ministry of Construction, which specifies the communication interfaces, instrument types, and codes for the four types of instruments.
In the water, gas, and heat industries, there is support from national policies, such as the ladder policy, the now emerging Internet of Things, and smart cities. In the non-utility sector, a self-managed self-collection fee collection platform is generally established. The country’s latest guidance document is Jian Ke [2008] No. 114 “Notice on Printing and Distributing State-Owned Organs, Office Buildings, and Large-scale Public Building Energy Consumption Monitoring System-related Technical Guidelines. 》 In July this year, the National Development and Reform Commission issued the "Guiding Opinions on Promoting the Development of Smart Grids" to improve the sharing of information resources in the coal, electricity, oil, and gas fields, support the collection of water, gas, and electricity sets, and build a cross-industry dynamic data integration platform for energy operations. Encourage the sharing and reuse of energy and information infrastructure.
Second, a typical case of Shandong Electric Power Company
Informatization collection creates a new benchmark for smart energy use. The State Grid has four pilot cities and five pilot provinces and cities, followed by pilot cities and provinces, 21 of which have been involved in 15 pilot projects. The four-in-one-Waisheng technology plan of the State Grid is to install a communication interface converter. This device can shield the water-gas-heat difference, because the water-air-heat regulation is not strong and the local standards are different.
In April 2015, Shandong Electric Power Co., Ltd. started the construction of a four-in-one pilot project. State Grid Shandong Electric Power Co., Ltd. uses the National Network Concentrator Type II, which uses full-wired RS485 and power meter data communication, as shown below. The characteristics of the program are: data set copy the physical link of the system, without modification; can shield water, gas, heat meter protocol, type difference; reduce the impact of water, gas, heat instrument failure on the power consumption information system; M-Bus can water The power supply of the hot-plate, the project is simple to implement; can access the mainstream water, gas, heat meter of the industry, no need to change; electricity, water, gas, heat data can be unified collection and management. The program has been carried out in some districts of Jining, Weifang, Weihai and Qingdao in Shandong Province and has reached more than 20,000 households.
“The application of smart grid systems and equipment avoids the errors caused by manual meter reading and greatly improves the accuracy of meter reading data.” Wang Xiangwei, deputy director of Shandong Power Marketing Department of State Grid, introduced the power consumption information contained in the smart grid. The acquisition platform also has a series of expansion service functions such as fee-controlled management, power calculation, and customer interaction, which greatly satisfy the customer's intelligent demand for electricity.
In addition, the State Grid Shandong Electric Power also implements the “Internet Power Service” mode. At present, there are more than 12 million electronic service customers in Shandong Province, including 8.19 million WeChat customers, 2.69 million Alipay customers, 480,000 handheld power customers, and 890,000 registered customers. A total of 121.73 million electronic payments were made, and electronic services took the lead among all units of the State Grid Corporation of China.
These advantages have created conditions for promoting the “four-in-one” acquisition and exploring the “generation and collection” operation mode. In April last year, after the State Grid Shandong Electric Power held a “four-in-one” pilot arrangement, the Jining Power Supply Company investigated the status quo of Jining’s public utilities meter management, advanced deployment, and self-pressurization, and formulated the “four-in-one” combination. Collecting pilot construction targets and holding special seminars, inviting companies in the water, gas, and heat industries to discuss the significance, feasibility, and difficulties of the "four tables together" and forming consensus.
In the next step, State Grid Shandong Power will be oriented to customer needs, with the goal of “one card, one-time payment, one-stop service”, to further enrich and improve the functions of the main station of the acquisition system, and to realize interconnection with the citizens’ service network in each city. Interoperate to give full play to the advantage of power online payment, third-party payment, and 10-minute payment circling to solve the problems of paying customers for multiple cards, multiple times, and multiple channels; through the new electronic service means such as WeChat, mobile phone APP, etc. , Cooperative companies and four-table customers, provide high-quality, efficient energy service support, build a new benchmark for smart energy information collection at home and abroad.
Henan Electric Power Company
Demonstration and promotion to allow more residents to taste the sweetness According to the State Grid Corporation of China in September 2015 before the end of the year 2000 completed the "four-in-one" collection pilot construction tasks, the State Grid Henan Electric Power Company quickly launched the "four-in-one" construction Work, choose Luoyang, Kaifeng, Zhoukou, Xinxiang power supply company as a pilot unit, establish a provincial and municipal two-level special control mechanism, and actively promote the pilot construction work.
State Grid Henan Electric Power organized Henan Province Power Metering Center to conduct research and analysis, formulate detailed technical plans, organize development vendors to deploy technical backbones, set up on-site testing environments, and complete the “four-in-one” function of the collection system within one month. It has provided strong technical support for the smooth advancement of the construction of the "four-in-one".
As of the end of November 2015, State Grid Henan Power has achieved a total of 2,172 “Four One Units” construction and collection work for Luoyang, Kaifeng, Zhoukou, and Xinxiang Power Supply Company, among which Kaifeng Power Supply Company completed the collection of 672 hot meters, and Zhoukou supplied power. The company and Luoyang Power Company completed the collection of 545 water meters and 530 water meters respectively. The Xinxiang Power Supply Company completed the collection of 425 gas meters, which was one month ahead of schedule.
“Establishing information sharing mechanisms in water, electricity, gas, and thermal fields, and implementing intensive and large-scale remote metering and meter collection can bring convenience to residents’ lives. Afterwards, water, electricity, gas, and even heating غير مجاز مي باشدts are It can be easily completed," said Qin Nan, head of the State Grid Henan Electric Power Measurement Division.
In accordance with the arrangements made by the State Grid Corporation of China, in 2016, State Grid Henan Power will promote the completion of the “four-in-one” construction task for about 70,000 households. The company will organize the pilot units to sum up the 2015 construction experience and prepare for the 2016 construction. According to the needs of the water, heat and gas management units, the information transmission platform will be built to ensure the safety of the meter reading data and the continuous monitoring will be completed. A "data deepening application upgrade. At the same time, the company actively explored the “four-in-one” business cooperation model, and focused on organizing the Luoyang Power Supply Company to communicate with the local Beijing Enterprises Water Corporation on the intention to carry out business cooperation. In 2016, the company plans to transform the investment interface, promote the scale of the customer, copy and charge, and customers. Information resource sharing and other aspects were discussed, and efforts were made to reach the metering standards for meter customers on behalf of them, and trials were conducted on business models such as copying and collection, and efforts were made to expand the demonstration effect.
Shanghai Electric Power Co., Ltd. copied three copies of the "pay-by" for many years
To be precise, there are four tables that can be copied: electricity meters, water meters, gas meters, and heating meters. With the exception of very few communities, there is currently no central heating in Shanghai, so only the top three households at ordinary citizens' homes are listed. Therefore, the “four-in-one” work carried out by the State Grid Corporation of China has become a “three-in-one” in Shanghai. By the end of 2015, 5,389 Shanghai residents had enjoyed the convenience of "three forms."
For "three-in-one", automatic data collection is the basic first step. Since smart meters have been widely used in Shanghai at present, the electricity consumption information collection system has also been fully covered, and thus electricity consumption has been achieved by automatic meter reading. However, the gas meters and water meters used in Shanghai are mostly traditional mechanical watches, and they have to rely on manual transcription. To achieve the "three-in-one", you must first overcome the difficulty of automatically collecting data.
To this end, the State Grid Shanghai Electric Power Company opened a power consumption information collection system to gas companies and water companies as a unified working platform. First, in cooperation with Shanghai Gas Group, it solved the technical obstacles in the communication frequency and communication protocol level of gas meters, jointly developed a new version of the agreement and developed a gas meter collection communication interface converter. Since November 2015, the converter has been widely used in the gas meter collection of various sites, and the effect is very good. At present, Guodian Haidian Power and Shanghai Gas Group jointly drafted the "Shanghai Gas Metering System Technical Specification (Discussion Draft)" and standardized the technical requirements for centralized gas meter reading.
On the basis of successful cooperation with Shanghai Gas Group, Guodian Hai Power also docked with the Shanghai Water Affairs Bureau, referring to the scale of the gas meter technology, and realized automatic collection of water meter data and system reception.
