All series modules of Lihewei passed the latest broadband carrier qualification test of China Southern Power Grid at one time

In 2021, China Southern Power Grid Co., Ltd. held a technical standard briefing on the “Low-voltage Power Line Broadband Carrier Communication Protocol (2021 Draft for Approval)”, and began to accept voluntary inspections from manufacturers. Our company responded positively and completed the update and iteration of technology quickly and efficiently. In view of the new technology specifications, the concentrator modules, single-phase meter modules, three-phase meter modules, I-type collector modules, and II-type collectors submitted by our company for inspection have passed the test at one time. The embodiment of technical strength has also laid a good foundation for further empowering the smart grid!

Cutting-edge transparent touch display technology – a new bright spot in the high-speed maglev transportation system with a speed of 600 kilometers per hour

The 600 km/h high-speed maglev transportation system developed by CRRC successfully rolled off the production line in Qingdao. This is the world’s first high-speed maglev transportation system with a design speed of 600 kilometers per hour, marking that my country has mastered the complete set of high-speed maglev technology and engineering capabilities.

After 5 years of research, CRRC successfully conquered key core technologies, the system solved problems such as speed improvement and complex environment adaptability, and achieved a major breakthrough in complete engineering technology. It is very fortunate that the LUMINEQ transparent display brand under Qingdao Sifang SIRUI Intelligent Technology Co., Ltd. also participated in the development of smart windows.

A LUMINEQ transparent touch screen is placed in the cab of the high-speed maglev train and the glass interlayer of the first-class side window. By touching the preset touch button “+” or “-” on the transparent display, passengers can adjust the light according to their own preferences to meet different shading needs, and the screen can be easily touched even when wearing gloves.
