Design of a smart lighting system based on electric power cat technology

Based on the power cat technology, a smart lighting system design is presented, which can be used for the smart upgrading of the old lighting system in buildings without wiring operation. The system consists of upper microcomputer unit, lighting management unit, power cat communication unit and smart switch with WIFI communication function. They constitute the bigger unit named as lighting management unit and control unit; the power cat communication unit consists both of them. Through power cat unit acting as convertor, the smart switches are controlled by the upper computer, in order to turn on/off the light. The circuits related to the system are given, the functions of both power line carrier communication and WIFI connection are tested successfully.
