Brief introduction of Qingdao Ding Xin Communication Co., Ltd.

Established in March 2008, Qingdao Ding Xin Communication Co., Ltd. is located in Qingdao Software Park, Shinan District, Qingdao, specializing in the research and development of power line carrier communication chips, centralized meter reading system products, bus chips and related products. The company has strong scientific research and production capacity in spread spectrum communication, signal processing, communication technology, automatic control, computer application, mechatronics and other fields. It is a high-tech electronic company that develops wired communication systems.

The registered capital of the company is 654.38+0.7 million yuan, and it has a group of technicians who have been engaged in R&D of centralized meter reading system for many years and have rich experience in design and development. More than 95% of the employees have bachelor degree or above, and it is a high-tech enterprise recognized by Qingdao Science and Technology Commission. The company has completely independent patented technology, that is, it uses the unique characteristics of three-phase electric phase difference of power line to synchronize with the zero-crossing point of power line as the time benchmark, and effectively uses the differential time period of each phase zero-crossing point to communicate, so as to ensure that the system can accurately distinguish the phase sequence from the ownership of the station where the electric energy meter is located. This technology has reached the international advanced level. At present, it has been popularized and applied in northeast, north, central and northwest provinces under the State Grid Corporation. It has been running very well in many complex fields and has been highly praised and trusted by users.

Qingdao Ding Xin Communication has developed a brand-new spread spectrum carrier communication system based on the characteristics of power line by relying on its strong technical force and adopting today's advanced technology. The newly developed TCX series carrier chip is a low-voltage spread spectrum carrier communication special chip developed according to the current domestic carrier meter reading market demand and power grid characteristics. The company has passed ISO9000 certification, with an annual output of 20 million chips, and invested more than 4 million yuan to purchase various testing equipment to ensure product quality. The bus chips independently developed by the company have proprietary communication technology, all of which are designed with innovative independent electronic technology, and have broad application prospects in industrial control, smart home and other fields.
