ã€Industry Focus in China's Instrumentation Network Industry】 In recent years, intelligence has entered more and more people's lives, and smart water meters and meters have also been gradually promoted. However, as an industry insider, what do you think about the four tables? What is the status of the development of remote meter reading that is being popularized? See this article for a detailed analysis.
Water meter reading policy background At present, China's smart water meters and meter development are still very slow, and now 90% of water meters are manual meter reading. In 1998, the State issued a document requesting the measurement of households, but it has not been implemented. In 2002, relevant departments such as the Ministry of Finance and the Ministry of Water Resources demanded the realization of a stepped water price by 2005, but it has not been implemented successfully. From a local point of view, some areas have begun to implement the ladder water prices, such as Sichuan Province has long-term planning, including how to design a water supply, how to accept, and the acceptance criteria of each table. The city of Changsha has begun requiring all new forms to be equipped with telemeters, and all ordinary forms will be changed to remote forms within 3-5 years. Recently, the State Grid issued a document requesting the promotion of four-in-one work. In general, the prospects for copying on the four tables are bright, but the roads are winding.
Water meter remote meter reading The current water meter installation environment is very bad, there are open-air, surface, the environment is dry, but also wet. Many people have never seen where their water meters are installed. Some of our remote watches were flooded and the data was gone. Therefore, we recommend an external antenna. Water meters have always struggled with the environment, not technology. In addition, in terms of measuring media, tap water has surface water, surface water, etc. Most of the northern part is groundwater, and 108 indicators need to be tested. The water in each city is very different. For some water meters with valves, this issue is relatively large. The electric medium is almost the same throughout the world, so the accuracy of the meter can be very high, and the water meter cannot, because the medium is too different. Many countries can use volumetric water meters, but domestic water companies cannot use them. Volumetric water meters have high accuracy, but a little sand can't be used. Therefore, we put the high-precision volumetric water meter on the drinking water. For power supply, the water meter uses battery power. As a smart meter company, 30% of our energy is devoted to circuit research, and 70% of the energy is researched on waterproof and moisture proof.
Water meters have many calibers, many installation methods and installation environments. Different user requirements, companies produce a variety of water meters, unlike electricity, the national requirements. There is no uniform standard for water meters. We have produced more than 100 varieties of watches. With respect to communications, electricity is doing very well. It is possible to monitor the communication of each watch and have a network card. But the water meter is not the case, the measurement bureau is no matter what the communication, the concentrator does not have the place to measure, will cause the thing that everybody makes can only be connected with oneself. Therefore, we also call for how to harmonize water meter communication conventions from the national technical level so as to achieve interoperability.
Application program 1, M-BUS/RS485 remote meter reading: data wiring bus type; data concentrator responsible for automatic meter reading, automatic upload data; management software can choose B / S, C / S two kinds of architecture.
2, wireless remote meter reading: The use of wireless point-to-point meter reading or ad hoc form of automatic meter reading, data concentrator is responsible for wireless watch management, ad hoc network routing management, automatic meter reading, automatic upload data. Through the management software, the battery voltage can be viewed in real time for easy replacement; the management software can use B/S, C/S, and two architectures.
3, GPRS direct transmission (Internet of Things meter reading): The use of GPRS remote transmission meter, direct data transmission to the management center; management software can be scheduled remote meter reading, data analysis, output of various data reports. Through the management software, the battery voltage can be viewed in real time for easy replacement.
Remote collection of typical case studies In 2008-2009, we made 130,000 water and electricity remote tables at 9 locations of PetroChina. CNPC's hydroelectricity is managed by a mining division and is an independent portal. But now every city has electricity, water, and water, and it's difficult to copy four tables. Our colleges and universities have also done some examples of water and electricity heat collection.
Summing up multi-meter remote meter reading, there is no problem on the technical level, mainly on the management level. For instrument companies, there is no problem. The key is that the power grid now has this idea. It depends on how water and gas heat are coordinated with each other. On the other hand, from the perspective of watch design, technology is not a problem. How to adapt to the environment is what we need to consider.
