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/T 188-2004 Household Metering Data Transfer Technical Conditions†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.
2. Typical Cases The Wasion Group is a domestic manufacturer of water, electricity, gas, and heat meters. Wesaw produces and sells over 15 million units of various types of smart meters.
Three-in-one self-management area typical application In 2008, Wasion Group has built more than 200,000 households of electricity, water, gas (three tables) data acquisition system, the system uses technology/products are the national network of four unified products Earlier versions. For example, PetroChina Oriental Geophysical (Hebei) Electric, Water, and Gas Meter Collection System includes 78 large-diameter water meters, more than 10,000 residential electricity meters, more than 20,000 residential water meters, and more than 20,000 acquisition equipment; The success rate of the table is above 97%, with a success rate of over 92%.
Chengdu University of Electronic Science and Technology Intelligent Network Energy Management System
In 2010, Wasion Group initiated the construction of energy-saving campus energy-saving supervision system, and more than 20 university energy-saving platforms have been built. The system includes 757 electronic energy meters, 60 remote water meter meters, access to air conditioning, lighting, security, monitoring and many other systems; 100% success rate on the date of data acquisition, and more than 98% success rate with copying data, 2012 3 In the month, it was jointly accepted by the National Ministry of Housing and Construction and the University Logistics Department.
Shandong Electric Power Co., Ltd. collected four examples of the State Grid, four lists of the first batch of pilot provinces and five cities, followed by pilot provinces and cities of 21, of which Wasion participated in 15 pilot projects. The four-in-one network technology of Wasion’s technical solution is to install a communication interface converter. This device can shield itself from the difference in water and gas heat, because the water vapor heat specification is not strong, and 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 system physical link, no change; can shield water, gas, heat meter protocol, type difference; reduce the impact of water, gas, heat meter fault on electricity information system; M-Bus can water The power supply of the heat meter, the implementation of the project is simple; can access the mainstream water, gas, heat meter of the industry, no 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.
Shanghai Electric Power Company, building a four-in-one pilot site in Shanghai's four-in-one pilot similar energy efficiency monitoring unit, a user has a concentrator to collect all the data is completed and then reported, large buildings, more users, basically It is wired, as shown below. The program features: stable and reliable communication, high collection success rate; M-Bus can supply power to water and gas meters to solve battery replacement; M-Bus communication bus is two-core and non-polar, convenient in construction and maintenance; high degree of system integration and reduction in measurement The construction of sharing maintenance costs; access to the mainstream water and gas meters in the industry, no need to change; electricity, water and gas data can be collected and managed in a unified manner; supporting the expansion of smart home applications.
III. Discussion and Application of Exchange Discussion The application of four-in-one pilots in the national power grid can promote the cooperation among electricity, water, gas and heat industries, and provide feasibility for multi-table fusion in water, gas, and heat meter fields; and promote the communication of power consumption information collection systems. The development of technology has promoted the renewal of industry standards for electricity, water, gas, and heat. If the original CJ/T188-2004 has already covered the content of household metering meters, the standard has been updated slowly and it has not been able to adapt to the status quo.
To discuss the selection of the communication technology standard for the water gas heat meter (fixed installation instrumentation) for the construction guidance document. Is it included in the GB50368-2005 residential building code?
Four tables copy the status quo attention spot application progress uneven
[China Instrument Network Industry Focus] With the popularity of the Internet of Things, more and more attention has been paid to the four tables. There have been many typical cases of copying across the country, but at the same time it also brings us thoughts.
