Through a lot of theoretical research and field experiments, the company has come to the conclusion that the low-voltage power grid has the characteristics of low noise, high impedance and stable voltage in micro-stages. Taking the zero-crossing point as the time reference, synchronous processing is carried out, and the zero-crossing difference period of each phase is effectively used for communication, which not only realizes efficient communication, but also accurately distinguishes the phase sequence, and meets the management needs of power companies to the greatest extent. This technology has reached the international advanced level.
At present, the company's products have a very broad application prospect in smart grid, electric energy information acquisition system, four-meter unified meter reading, fire protection system, home automation and other fields.
The number of carrier chips and bus communication chips running in the field has exceeded 10 million. Our products have been used in four countries and 29 provinces and cities in China. The running system can successfully deal with all kinds of complicated situations in various regions, and has been highly praised and trusted by users.
From June 5438 to October 2009, the company invested more than 30 million yuan to develop professional carrier chips and special bus chips with completely independent intellectual property rights. At present, the chip sample has entered the testing stage and was put on the market in February of 20 1 1 year. The use of new chips will further strengthen the company's technological advantages, reduce customers' production costs and bring more profit space for partners. The dedicated bus chip will also be the first in the world.
