Power lines can also be used at the same time as cable, telephone line, TV cable? It has now become a reality from the idea. On the 16th, Mr. Pan of Room 101 in Tianyuan Garden, Fuzhou, inserted a 200-megabit BPL (Broadband Broadband) modem into a 220-volt common power outlet. He could immediately use the computer to browse the Internet, play games, chat with voice and video, and watch HD numbers. TV.
"It's very practical, and the video and audio signals are all very clear. Even if all the appliances in the home are used at the same time, you don't have to worry about losing the connection." Mr. Pan used the Internet for several months. He felt it was very convenient to use.
This "magic" BPL modem is a product developed by Fujian Electric Power Research Institute using BPL technology. BPL is a power line carrier communication technology that allows Internet data to be transmitted over the power line. The Institute had already developed power line communication (PLC) technology as early as 2002, which is the technology of using the power line to transmit data over the Internet. After painstaking research and years of development, PLC has now transitioned to BPL. While further increasing the speed (up from 10MB to 200MB), it has successfully solved problems such as signal attenuation and noise interference, resulting in more stable and smooth network transmission. .
It is understood that the hospital's BPL technology has reached the international advanced level, and is currently the only domestic manufacturer that can independently develop BPL chips. The hospital's BPL technology products are sold in more than 30 countries, and the latest 200 megapascal products have also been sold to the United States, Brazil and other places.
"BPL has undergone rapid development over the years, and its application areas are also becoming wider and wider." Wang Dongfang, technical expert of the Fujian Electric Power Research Institute, said that in practical applications, BPL has been extended from civilian use to industrial applications. Tables, submarine cable signal monitoring, port operation automation control, train communication, mine communication, smart home automation and street lamp automation control, etc. are all BPL-related and mature fields. Wang Dongfang stated that as the technical difficulties continue to be overcome, the application of BPL will continue to expand.
According to reports, Fujian Electric Power Test Institute is actively promoting smart home pilot study. At present, a smart home test site has been set up in Cangshan District of Fuzhou. By then, pilot residents will move towards the era of smart home life. Fast after work, just a phone call, a set of instructions will be automatically sent to the home: start the water heater, rice cookers start cooking, air conditioning, automatic preheating ... ... not only home appliances can be automatically controlled, BPL power line broadband meter reading system can help people reasonable Utilize power resources and prevent theft.
