基于CAN总线的室内LED智能控制器的设计+程序(2)
(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 lull 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 control convenient. The system is designed and reformed in utilities, railway stations, schools, and other buildings. It has broad application prospects.
