On hardware configuration of the present invention, be divided into Intelligent Node Controller, power line, intelligent Centralized Controller and server.Its topological structure is star-like and bus type structure, is bus type structure, and between terminal node and controller, is hub-and-spoke configuration between terminal node and terminal node, and one of them terminal node is an Intelligent Node Controller and is connected to a street lamp.
Between terminal node and terminal node, transmitting control information and node device information by power line, can be direct or indirect between intelligence Centralized Controller and any one terminal node communicate by letter, terminal equipment information and server controls order are exchanged and passed on, and control command information exchange is crossed directly connected terminal node and is forwarded and received and carry out by corresponding node.Node device information is sent to server data administrative center by intelligent Centralized Controller information processing packing by GPRS network, and control data corporation is processed information extraction by message data and deposited database in and be presented to keeper and control the page.
Intelligence Centralized Controller is connected to by interface on the interface of any terminal node, starts communication work by microprocessor controls GPRS module.It carries out flow process for being first connected with server, and request msg Connection Service with transmission querying command, is finally obtained terminal node information and also arranged and send to server data administrative center to process after then connecting.
