Abstract

The invention discloses an industrial mine lamp illumination energy control network system. All lamps in a factory zone form a network and are combined together by means of a LIN bus communication data mode, the LIN bus data mode is adopted for communication between a central controller W of the system and each main node, and the LIN bus data mode is also adopted for communication between each main node and each branch node. The whole system has high reliability and strong interference resistance, forms all nodes of the network per se without depending on the outside, and has good universality and strong combination; multiple sub networks can be combined into a bigger network, so the system has a few hardware resources; the nodes can be connected only by a metal lead, so the system has high flexibility; and the system can flexibly increase or reduce the number of the nodes according to the actual illumination layout condition of the factory zone, and can save a large amount of energy for industrial mine illumination.
