The System Of Power Line Carrier Long-distance Collect Meter

The system of power line carrier long-distance collect meter gathers the meter by terminal unit, and transferred the data by Power Line. The constitution of power line carrier communication changed high frequency, not only consider acoustic noise, but also the communication distance. Otherwise, the probability of communication successful depends on the power line net and linkup junction.GIS provided with powerful analysis ability, perfect organize model and system of space data and attribute data, not only can deal with the mass data,but also can analysis topological of space. So, The system of power line carrier long-distance collect meter will become perfect by using GIS technology. These result s' primary content is:â… . We using the platform of ArcGIS 9 because we need the platform have ability of second development of GIS. The ArcGIS 9 meets not only graphical interface require but also circuital analysis requires.â…¡ .The theory of gather meter, the introductory of low pressure power line communication, the design of system and held hands of communication and verify. â…¢.Efficient implement the data transmission and management, by using theGeodatabase object-orientation spatial database. IV. Efficient implement the query of the optimal linkup junction and assistanthard decision.These results of this dissertation not only apply this information system but also are useful for homothetic systems.
