The Design Of The Stadium Intelligent Lighting Control System Based On CAN Bus

In order to achieve optimal architectural lighting distributed control, architectural lighting intelligent control system based on CAN bus has been analyzed and explored. The system achieves the effect which system based on CAN bus adapt to relatively concentrated group of buildings and the planning and design of the construction body needs intelligent lighting control. It conforms to architectural lighting intelligent, network-based, scientific management, the direction of development of the green and energy saving policy.Dalian University of Technology Liu Changchun Stadium lighting control system still uses traditional control mode, the characteristics of the traditional control method as follows: the mode over-reliance on manual control, the relative dispersion control, low intelligence of management, serious waste of resources. According to the these shortcomings, stadium lighting intelligent control system based on CAN bus is designed, and has the ability to adapt to different venues of the corresponding lighting scenarios. System hardware parts adopts microcontroller STC89C52, controller SJA1000,82C250transceiver as core chip in this paper, designed of intelligent relay nodes. In the software section, the system use self-defined CAN bus application layer communication protocols, programming in C language, to implement the bus node communication function.The system has the following functions:(1) The system uses a multi-level network structure, networking control object. In the lower, the system makes use of safe and reliable field bus technology to achieve acquisition and control transmission. In the upper, to meet the more open connectivity needs, network bus connects with the LAN, facilitating remote monitoring and sharing of network resources.(2) The system is feature-rich, easy to configure, and applicability. Combined with the detection, scene control, the system satisfies stadium lighting intelligent, scientific and unified management, the pursuit of the art of the best lighting effect and energy saving effect.(3) Given full consideration to the CAN bus network system compatibility and cost-effective, CAN bus network system is flexible networking and has cost-effective advantages.(4) Taken full account of the security and reliability of system operation, the system is easy to maintain. Automatic control and manual control are taken into account. Based on the CAN bus intelligent lighting applications technology is mature. Through the practical application of engineering verification, energy-saving effect is good and distributed con■convenient. The system is designed and reformed in utilities, railway stations, schools, s and other buildings. It has broad application prospects.
