Development of Relay Device in Monitoring Data Management of Cable Circulation in Urban Power Grid

The monitoring points of cable circulation in cities are relatively scattered. The on-site collection devices restricted by the power supply, installation site and communication distance are usually unable to store large amounts of data or transmit data over a long distance. In this thesis the relay device of data management is developed, realizing the management and sorted storing of the data of the collection devices of close-distance wireless receiving data, and sending the data to remote places through the GSM/GPRS network. Therefore the scattered data can be transmitted to computer analysis and management system over a long distance after centralized processing of scattered data and long-distance data monitoring and comprehensive analysis can be realized.
