“Our self-developed chip, installed in the high-speed power line carrier communication (HPLC) module of the meter, can realize remote automatic meter reading, real-time power purchase and upload power consumption data.” A few days ago, in the smart factory of Shenzhen Guodian Technology Communication Co., Ltd. (hereinafter referred to as “Shenzhen Guodian”) located in Dalang street, an employee held a circuit board and pointed to a chip and told the Shenzhen business daily.
Nowadays, many users only need to turn on their mobile phones to query the power consumption information at home in real time. The key to realize “remote automatic meter reading and real-time power consumption information query” is the application of high-speed power line carrier communication module.
The successful application of this technical achievement is inseparable from Shenzhen Guodian company, which has been deeply cultivated in the field of power communication for many years. In an exclusive interview with Shenzhen business daily, Wang Xiang, chairman of Shenzhen Guodian, said that providing “safe, stable and reliable” products to help the industrial digital transformation of power grid is one of the missions of Shenzhen Guodian since its establishment.
Founded in 2003, Shenzhen Guodian is the first enterprise in China to apply high-speed power line carrier communication technology to the field of power consumption information acquisition. It has the only power line communication application technology laboratory of State Grid Corporation of China. Its high-speed power line carrier communication technology is in a leading position in the world and has participated in the formulation of relevant international standards.
Wang Xiang said that there are more than 500 million power users in China. In order to solve the problem of data acquisition of electric energy meters, the industry has tried a variety of communication technologies. The high-speed power line carrier communication technology developed by Shenzhen Guodian Power Co., Ltd. transmits communication signals through power lines without wiring. According to the characteristics of power grid signals, a special communication chip is developed, which is efficient and stable and solves the dilemma. In the past three years, high-speed power line carrier communication modules have been applied to thousands of households, and nearly 200 million HPLC communication modules are produced in Shenzhen. By the end of last year, Shenzhen Guodian had supplied 193 million HPLC communication modules.
As a high-tech enterprise deeply engaged in industrial chips for many years, innovation is the soul and characteristic of Shenzhen Guodian. Shenzhen Guodian has led or participated in 141 science and technology projects, including 9 at the national level and 5 at the provincial and ministerial level; It has won 8 provincial and ministerial scientific and technological progress awards and 58 scientific and technological awards at all levels in the industry such as the State Grid; Obtained 2 integrated circuit layout design registrations, 82 patent authorizations, and applied for 4 international patents; Participated in the formulation of 43 standards, including 2 international standards and 3 national standards.
In addition to the fist product HPLC communication module, Shenzhen Guodian has also vigorously expanded its businesses such as chip devices, IOT sensing, intelligent terminals and platform data. A series of core products and solutions have been widely used in power systems and other industrial fields.
In recent years, the vigorous development of Shenzhen Guodian in the application end of domestic industrial chips is inseparable from the deep cultivation of its parent company Beijing Zhixin Microelectronics Technology Co., Ltd. in the field of industrial chips. The company is the largest industrial chip design enterprise in China, with more than 180 industrial chips in eight categories.
The company is stepping up the alternative application of domestic chips in the fields of energy and power, rail transit, automotive electronics, petrochemical industry and so on, so as to contribute to solving the problem of “stuck neck” of chips. Wang Xiang said.
Rooted in Shenzhen for nearly 20 years, Wang Xiang believes that the high-quality business environment in Shenzhen has provided rich soil for the development of Shenzhen Guodian. In 2019, the company’s headquarters moved to Dalang street and began to build a smart factory to promote smart manufacturing. With an area of nearly 20000 square meters and a cumulative investment of 300 million yuan, the smart factory was rated as one of the top ten digital transformation benchmarks in Longhua District. After the completion of the smart factory, the company not only meets its own capacity needs, but also provides intelligent manufacturing solutions for upstream and downstream customers of the industry, further releasing the Shenzhen New Industries Biomedical Engineering Co.Ltd(300832) kinetic energy of technological innovation.
“Promoting the innovative application of industrial chips is our long-term development goal.” Wang Xiang said that next, Shenzhen Guodian will provide software and hardware products and overall solutions for power IOT and industrial IOT with the help of key carriers such as intelligent manufacturing and innovative technology. “Based on Shenzhen, build the industrial chain ecology of industrial chips in the Pearl River Delta, and help the digital transformation of power grid and manufacturing.”
