It’s based on CAN the design we use master and slave work The main munication between the master node and multiple slave nodes to make the remote realtime monitoring of lighting equipment successful. The master node uses the ARM7 family NXP LPC2119 microprocessors and integrated to its internal CAN controller and PCA82C250 transceiver design hardware schematic diagram of the master node, and create the hardware circuit board of the master salve node use STC89C52 microcontroller SJA1000 standalone CAN controller and PCA82C250CAN bus transceiver design from the node hardware schematic diagram and also create two nodes put the master and slave node experimental circuit board to the main work to constitute a main and some slaves lighting control local area work. U sing the work to research and experimental testing of the CAN bus lighting control system. In this paper a detailed introduction master and slave node of the CAN bus ,hardware and software design principles, the principle of CAN bus munication, the formulation of the CAN bus application layer protocol, SD card storage technology, TFT color display, touch screen technology and other practicalfriendly TFT LCD is one of the most wonderful of this the design,we simulate industrial control process flow diagram of the bus involved in the process, light equipment, boards, carefully drawing then make the control system more clear image and vivid. Advanced and convenient touchscreen input technology are the second highlights in the it apply a convenient input to the third highlights is that Light equipment offline detection. So We use from time to time ask, from the node offline detection. In short, in this design, the master node to multiple remote setup and monitoring functions of light equipment from the node offline detection, run munication indicator, updated in real time slave node With independent settings, control the function of the lamp device of the node from the node. The overall system is reliable, normal munication, the munication congestion, crashes and so on. And develop system software and hardware with a certain significance of application to achieve effective control of the lighting equipment. Keyword: CAN bus； node； Lighting
