Research And Design Of Wireless Lighting System Based On ZigBee

With the development of society and economy, the requirement of urban infrastructure construction has been improving. As the urban construction of essential utilities, lighting system is related to the immediate interests of citizens, and lamp control and management level shows a city's modernization degree. How to save energy and improve lamp energy utilization have become urgent problems in urban lighting system. Therefore, it appears important to provide an effective and reasonable method of remote lamp management. Wireless communication technology has been widely used in monitoring and control field due to the development of wireless communication and the increase of wireless products performance. As a new wireless communication technology, ZigBee provide a suitable solution for lamp automatic control with its low power consumption and large capacity of network communication reliability. Intelligent lamp control, energy saving, and convenient management purpose can be realized with the comnination of ZigBee technology and various new power controllers.To solve the realistic problem of traditional lamp control as its unflexible management and maintenance difficulties, a set of remote control and data collection system based on ZigBee communication technology has been designed. ZigBee network is applied in tradional industry as the data transmission medium with wide network coverage, reliable operation and strong anti-jamming capability advantages, etc. The system provides an efficient and practical management solution for lamp control system. In this thesis, system implementation scheme of hardware and software structure of monitoring center and remote control terminals has been presented, and ZigBee network will be analyzed in details.System hardware includes coordinate, router and terminal equipment installed on lamp nodes. When the control centre procceeds remote operation, the command will be transmitted to the target in a compositive way of ZigBee-GPRS, then the information will be returned by nodes and displayed on monitor through serial port. The system design and production has been finished, including circuit design of ZigBee communication module, antenna design and soft programme. Prospective target has been realized by PCB and software debugging. Two new antenna designs with SMA interface are used in coordinator and router or end device with the characteristic of directional radiation and omnidirectional radiation respectively. The design purpose of high-gain and low production cost was realized. The application software written in Visual Basic 6.0 provides real-time monitoring and control interface terminal for staffs. The concept of Ad Hoc network added in ZigBee system and design of a new self organization network is a further application of ZigBee system, realizing the purpose of low power consumption and flexible network.The wireless communication system based on ZigBee technology provides advanced and practical solutions for lamp management may realize the target of intellectualization, informationization, high reliability and low cost of the monitoring and control system.
