| Abstract: | An non-line security and protection control system （system without power line）, including its design and fabrication as well as evaluation of the efficiency of its model machine, is presented. The system, consisting of a signal-power mixer, a coaxial cable, a signal energy compensator and a signal-power separator, requires a coaxial cable instead of power line to transmit electric power, video, audio and data signals. It is indicated that the system can lower the cost of manufacturing and maintenance while saving materials and construction time. |
