Design And Realization Of Building's Langscaped Light Control System

Along with the rapit development of the economy, the speed of the urbanization process increased even faster, the urban landscaped light's importance is promoted. It becomes a important topic to design an advanced landscaped light remote control system in order to increase urban fascination and competence. This paper focuses on several problem of low-class landscaped light remote control system in both home and abroad, these problem include : none standardize, low speed in communication, low reliability and hard dynamic controlling. On the contrary, the high-class device also has some problems such as the high price and the complex interface, so it is not suitable for this system. Therefore, this paper discusses the real-time related problem of ethernet, design and realize the landscaped light remote control system based on industry ethernet. These work include:1) Analyze the total demand of the landscaped light control system and design the system architecture, choose the communication method of the system, analyze the performance of embedded controller, embedded operating system and embedded protocol stack.2) Design the detail of the hardware and software of the landscaped light control system. According to the concrete demand of the network control node, use the 32 bitprogrammable CPU and the real-time operating system to design the intellect ethernet control node to meet the real time performance and the synchronous of the system.3) Aimed at the demand of the overall control and human interface, designed the control software in the side of the host computer and realize a large number of nodes' schedule in network system to meet the needs of multinode syschronous control.4) Based on the designate of the system software and hardware, a test is raised to detail the network's performance and speed.The main feature and advantage of the system includes: simply realizing, high stability, large range programmable dynamic control at the same time. This system saves the cost and has a higher value.
