Design And Implementation Of Managment Platform For Wireless Meter Reading Network Based On ZigBee

As the rapid development of wireless sensor network and the network technology, the traditional artificial meter-reading system cannot have satisfied people and utility requirements. Now users hope to have a convenient and efficient way to query information query and capture to expend; Public sector hope to have a kind of fast, safe and reliable system for business management. These requirements at present already solved; At present a lot of functional management system is gradually application in public sector, these systems are playing an important role. This paper mainly introduces ZigBee wireless meter based on management platform of design and implementation, this system is applied with water, electricity, gas, and other departments, to implement the automatic meter reading and quick network management.This paper mainly introduces ZigBee wireless meter based on management platform of design and implementation. ZigBee is a new type of a new kind of short, low power consumption, low data rate, low cost, low complexity, wireless network technology,in addition,ZigBee is to support the bidirectional communication. The Ad hoc network is the network which can achieve automatic networking and multiple hops forwarding. Management platform is used for network management, its functions include:the node management, network management, network node parameter condition management and the topology of the network management. Management platform can send command to the network,change network parameters and introduce the network information through the network topology updates.This paper mainly introduces the design and implementation of a management platform.Management platform can be divided into several modules according to the function, these modules is respectively:Repeaters management, node status monitoring module, network parameters management module, network topology management module, database module and login interface module.Repeaters management module is used to manage the network Repeaters.Independent Repeaters can send network frame for detecting detection, net when I received the father sent network nodes, after the net received the detecting response frame from the father net to set network time synchronization. Node status monitoring module are used for node status management, network nodes send periodic node status frames to manage and update the node status.the nodes include:Intelligent terminals, Repeaters, Base station. Network parameters management module is used for maintenance and management of network parameters, network parameters include:PAN ID (ID), network nodes in network maintenance cycle, network parameters updating cycle, time synchronization cycle, node status transmission cycle, node data transmission cycle, the most architectural node number, maximum Repeaters number (routing), the maximum number of intelligent terminals, maximum network depth. Node regularly send network parameters request frames to keep the renewal and the maintenance of network parameters. The node judge the frame after receiving responser then the network state updates. The topology of the network management module is used to manage network topology of network maintenance. Node send periodic frames and determine whether in nets, if the node is not nets or across the link has new node to join, network topology can undertake corresponding change, thus maintaining with the actual network topology synchronization. The database model is used for the preservation of the network data. Login interface module is used to carry out land management, so as to ensure the security of the system operation.This chapter 3 and chapter 4 introduce the management platform design andimplementation in detail, mainly include the system of frames, sequence diagram, flow chart.It is convenient to the reader. This paper gives a detailed design and realization process, to some figure and table were introduced in detail.The last subtotal of the chapter 4 introduces management platform interface, and the realization of the function, and interface of these functions are simple analysis. In the fifth chapter basically are summarized in this paper, and looks forward to the future development direction.
