Lao Wang is a water meter reader. He is in charge of an old community. On meter reading day, he has to mobilize in advance and post a flyer on the door of each unit in the community, stating when he will go to read the meter and asking people to leave someone at home or post the water meter number on the door. On meter reading day, he has to knock on every door. Although he speaks politely, there are still some people who give him a cold face. In addition, after walking down several buildings, he is often so tired that his legs are weak, but there are still many households where no one is at home and no numbers are left on the door. Some residents will send text messages according to the contact information he left on the flyer. For others who don’t have any information, he may roughly estimate according to the numbers of last month. Lao Wang envies his colleagues in charge of new communities. They don’t need to climb stairs or "disturb the people". They can do automatic copying and automatic billing on the computer, which is convenient and efficient.
At present, in many areas of my country, manual meter reading and charging are still widely adopted. Meter readers like Lao Wang are an ordinary but unique position in many water companies, gas companies or power companies. The traditional meter reading method has brought a lot of trouble to both meter readers and users. What Lao Wang envies is remote meter reading, which is a good way to solve these troubles.
Remote meter reading is a convenient system. Through the data collector, the signals of water meters, electricity meters, gas meters and heat meters connected by multiple branch lines are collected in sequence at regular intervals, and the data are processed, stored, and finally transmitted to the computer network to realize remote and automatic meter reading. With the development of science and technology, especially the emergence of newly built smart communities and high-rise residential communities, this remote meter reading system is more needed. The Ministry of Housing and Urban-Rural Development has also clearly stipulated that having a remote automatic metering system for water, electricity, gas and heat meters is one of the necessary conditions for intelligent communities.
The development of remote meter reading systems in my country has a history of more than ten years, and many companies producing intelligent metering instruments have emerged. Hangzhou Jingda Electronics Co., Ltd. (referred to as "Jingda") is a long-established professional manufacturer of intelligent meters. Recently, this magazine interviewed Mr. Xi Ke, General Manager of Jingda, and listened to him talk about Jingda's dream of intelligent civil instruments.
The "kingdom" of intelligent instruments of "scholar-entrepreneurs"
In 1987, Xi Ke graduated from the Electromagnetic Metrology and Instrumentation Department of China Institute of Metrology. In the same year, he stayed in school to engage in teaching and scientific research. He has been committed to the innovation and intelligentization of measuring instruments and systems. In 1994, he went into business and founded Jingda. In view of his teaching and scientific research experience, the industry calls him a "scholar-entrepreneur". This is indeed the case. The biggest hobby of this general manager is to stay in the laboratory to "tinker" with the technical research and development of his instrument products.
Since the start of the business, Xi Ke has led Jingda through nearly 20 years of history, overcoming difficulties in the intelligent instrument industry, and has grown into a provincial high-tech enterprise integrating the development, production, sales and service of intelligent metering instruments. It has modern factory buildings and its products involve various types of civil intelligent metering instruments and corresponding testing equipment such as water, electricity, gas and heat.
Jingda's smart water meter series products won the "Science and Technology Achievement Award" from the Ministry of Housing and Urban-Rural Development at the beginning of its launch. The main metering products, smart IC card water meters, water and electricity sales systems, remote water meters and centralized reading systems, have many national patents and have been recognized by domestic and foreign users. Excellent cases are everywhere.
In 2009, Jingda was responsible for the construction of civil instrument transformation projects at six bases of CNPC, with a total of 150,000 water, electricity and gas meters transformed. The transformation of two bases won the "Excellent Project Award" from CNPC. Ordinary instruments are transformed to meet the standard of remote monitoring and intelligent networking. In other words, anywhere in the country, as long as there is a network, CNPC can monitor the performance of any instrument in these six bases in real time, and even if authorized, it can realize the function of remote valve closing. "Our meter reading success rate has reached 99.5%, which is not found in the large-scale civil water meter records in China." Xi Ke said proudly.
Jingda is not only a member of the China Water Meter Association, but also a member unit of the revision of the new industry standard "CJ/T133-2007IC Card Cold Water Meter". The users of the products are all over the country, and they are also applied in South Africa, Brazil, Chile, Turkey, Mexico and other countries. The export volume of smart water meters ranks first, becoming the first export brand in the domestic smart water meter industry. In order to ensure that every user can get fast and effective service, Jingda has offices or branches in Beijing, Guangzhou, Xi'an, Shandong, Urumqi, Chongqing, Chengdu, Changsha, Shijiazhuang, Wuhan and other places, with a complete after-sales service system.
Xi Ke said that at present, we are mainly committed to the research and development of civil metering instruments and exploring the development path of civil metering instruments to achieve intelligence. Combining products with modern network technology to realize the intelligence, diversification, specialization, multi-function and networking of products, and further promoting the development of the industry is the direction we have always adhered to.
The key to success is technology
Xi Ke said that the key to Jingda's success is technology.
R&D is Jingda's strength. Located in Cangqian, Hangzhou, the "Jingda Technology Park" covers an area of 30 acres and a construction area of 40,000 square meters. It is one of the largest research and development and production bases for smart meters and systems such as water, electricity, gas and heat in China. Xike is a technical person. Excellent technical leaders determine that Jingda has a very obvious advantage in technology control. Winning with technology is the key to Jingda's winning the market.
Through more than ten years of hard work, Jingda has built a young, professional and high-quality R&D team, which has promoted the company's continuous technological innovation.
Jingda has independent intellectual property rights from software to hardware, and has advanced intelligent instruments and calibration equipment. In Xike's concept, product quality is the vitality of the company. The company strictly implements the ISO9001 quality management system standard and has passed the Malaysian national quality international water meter standard ISO4064 test and the EU EU certification. It is currently the only water meter manufacturer in China that has passed both certifications.
In order to continuously innovate existing technologies and keep pace with international advanced intelligent instrumentation technology, Jingda, while focusing on independent research and development, is also constantly seeking cooperation with other technologically advanced countries in the world. It has established cooperative relations with companies in Turkey, South Korea, the United States and other countries to jointly develop and sell various types of intelligent metering instruments and meters with international leading levels, such as electronic direct-reading gas meters and electronic direct-reading water meters.
Turkey's BAYLAN is a large water meter manufacturer that includes upstream and downstream production lines. It is also the largest water meter manufacturer in Europe. The boss of the company visited 13 peers in China and found that Jingda's technology surpassed his own. After calculation, it was very cost-effective to import IC card water meters from Jingda, so he resolutely decided to shut down his own production line and cooperate with Jingda. At present, Jingda has an annual production capacity of 1 million smart water meters, 300,000 smart gas meters, and 300,000 smart electric meters, among which the export proportion of smart water meters accounts for 30% of the output.
As a professional R&D enterprise of smart metering instruments, Jingda has always focused on the technological innovation of its products. It has won honors such as "the most promising enterprise", "the top three enterprises in technological innovation and comprehensive strength", "the most influential brand", and "the most respected enterprise" in the smart water meter industry for many consecutive years, highlighting the brand advantage of the company in the industry.
Product guarantee under technological advantages
There are many manufacturers of smart meters in China, but the production scale and product quality vary greatly. In particular, some companies cannot solve the problems of products in time, and some even simply close down and leave, which brings great trouble and losses to users and also has a negative impact on the entire smart meter industry.
Jingda relies on its own technological advantages to have products with high quality assurance. This is the case with Jingda's multi-meter remote meter reading system.
Electronic direct reading water meter: PPO material, healthy and environmentally friendly, saving resources; full electronic direct reading, leading the new trend of water meter development; high sensitivity, accurate measurement with automatic correction function; M-BUS/RS485 bus communication mode; low power design; communication line break does not affect correct measurement, data is permanently stored; built-in valve, support remote control.

"Water Company Special Management Software" docking.
Jingda remote centralized reading control system adopts a three-level architecture of "centralized reading data center-data concentrator-metering meter" and a two-level transmission mode. It has obvious advantages: various interfaces are reserved for the meter itself, which fully meets the technical requirements of the Ministry of Construction and public utility meters; low cost, easy wiring construction, simple maintenance; reliable operation. According to the statistics of 150,000 remote meters installed in PetroChina, water companies, colleges and universities, enterprises and institutions in the past three years, the success rate and accuracy of meter reading are both over 99%, which is a meter reading system that can be widely promoted and used; data collection is real-time, and information is provided in a timely manner; a digital energy management system can be established to analyze the energy consumption of a certain area or the entire city, and provide a decision-making basis for energy conservation and emission reduction.
Xi Ke said that at present, the management departments of water meters, electricity meters, gas meters, and heat meters are different, and they read and pay independently, which wastes a lot of social resources and brings a lot of trouble to users. There is still a long way to go to truly establish a unified four-meter remote transmission system, and it still needs strong promotion from relevant government departments!
In any case, in line with the business philosophy of "product quality is life, customer satisfaction is the purpose", Jingda is determined to build the leader of China's smart meter industry and become a professional supplier of civilian smart metering instruments towards the world.
Although there are still many users in the market who are skeptical and cautious about the stability and anti-magnetism of remote meters, Jingda, which has a long history of development in the field of smart meters, has greatly reduced the risks of these products, and the product performance has reached the international leading level. Jingda remote meters are further divided into wired remote transmission, vertical remote transmission, photoelectric direct reading, and large-caliber remote transmission lamps. The data concentrators are wired remote transmission and wireless remote transmission. The products have small starting flow, high measurement accuracy, automatic error repair function, low energy consumption design, and some products also use PPO environmentally friendly energy-saving materials, which conforms to the product development concept of health and environmental protection. These products have been widely used throughout the country. Many subordinate units of PetroChina and water companies, universities, and well-known hospitals in many cities across the country have used Jingda's remote meter reading system, which has a good effect and won wide reputation from customers, playing an important role in water peak reduction and valley filling. Therefore, from the perspective of water-saving effects, the shorter the meter reading cycle, the more conducive it is to highlighting the water-saving effects and forming water-saving awareness.
【Product escort, quality first】
As the saying goes: Opportunities always come to those who are prepared. Fools miss opportunities, wise men seize opportunities, successful people create opportunities, and opportunities are only for those who are prepared. The role played by smart water meters in the implementation of the tiered water price policy is unquestionable, but the requirements for product quality have risen to a considerable height. Hangzhou Jingda Electronics Co., Ltd.
