Wireless system design of power line field operations

With the introduction of the concept of intelligence power grid,power grid is gradually strengthening scientific and technological means of monitoring the implementation of maintenance of their own power,especially in the overhead transmission line construction,maintenance and monitoring.Because the work sites are in remote areas in the field,how to solve smooth communication links,thus real-time to maintain power system information exchange between work on-site and background command center is an urgent need to address the problem.This paper presents a new wireless communications platform.This design combines IP digital spread spectrum wireless private network with 3G wireless public network,not only for the power field to provide a wireless communications platform for the construction,but also has wide bandwidth,high transmission rate,not affected by the terrain,simple set-up and low cost,completely solves the communication field work island.
