There are a large number of information intelligence boards in China, among which more than 20,000 sets are independently developed, produced and manufactured by Shanghai sansi, and the number of information boards technically originated from Shanghai sansi is even larger.
(2) induction screen: full lattice induction screen, optical band induction screen.
In the expressway, the main function of the induction screen is to guide the driver to travel intelligently and safely. From the practical point of view, outdoor induction screen selection of strong protective performance, support data self-storage, high energy efficiency design of the thoughtful LED induction screen, is conducive to stable operation in outdoor all-weather.
