(The design scheme is aimed at the situation of industrial enterprises with large factory area, many and widely distributed production plants, large span of perimeter walls, and complicated construction monitoring system design and construction wiring. We recommend the use of broadband common cable "one line" monitoring system. The monitoring system has unique advantages, which can solve the problem of long-distance transmission in the factory area, solve the problem of electromagnetic interference caused by mechanical equipment in the factory area, and solve the problem of multiple points and difficult wiring by means of common cable transmission. Discuss failure, everything from principles to equipment, hope you like it.)
