| In recent years, with the development of wireless sensor network, and its application isalso more and more extensive, including environmental monitoring, military control,industrial safety, communications radio, the medical service, etc. Among them in intelligentnetwork monitoring field, the wireless sensor node decorate in tower or high pressure onthe transmission of sensitive data collection and send, real-time feedback all parts of thestate so as to achieve the transmission lines online monitoring and management.This thesis based on the analysis of the present situation of the domestic and foreignresearch on in-depth research for uhv transmission lines the characteristics of on-linemonitoring system, and put forward a kind of hybrid networking transmission based onreliable transmission lines on-line monitoring system networking method, the monitoringsystem network of wireless sensor network, WiFi network, OPGW optical fiber netscomposition. Wireless sensor network management of the collection of data, WiFi networkin charge of data transmission, the backbone optical fiber nets relay will collect the datasent to the monitoring center. This paper introduces a design to adapt in large-scale longdistance of wireless sensor network routing protocols, and define the data structure, andpresents the algorithm process, this algorithm thought is: mass of long distance in wirelesssensor networks because of how to avoid the distance between the nodes is greater thanthreshold brought extra energy losses, through the comparison with other agreement givesthe agreement in the energy loss, remaining node number, the total amount of data onadvantage.For OPGW optical fiber nets in this paper, according to the its physical propertiesbrought forward a network connection model of surface league, high pressure on thetransmission of the optical fiber composite ground into several strands overhead, againthrough the cross connected to optical fiber connection way on a switch so as to realize themultilevel reuse the reliability of data transmission network increases with markov methodfor different analysis of the reliability of the cascade mode are analyzed in detail, and givesthe reliability contrast figure, prove the compared with the traditional connection under theway of advantage, finally, using the don’t pay product and the algorithm in the secondarycascade mode of the optical fiber transport network reliability. |
