Distributed Monitoring System, In The Highway

Textual work mainly what to aim at is the superhighway system, aiming at the our country superhighway service level low, go through the condition that ability differ, the superhighway distribute type supervision system can provide to drive the solid hour that the vehicle and roads carry the camp circumstance to supervise and control to the superhighway, various supervision data that analyze to collect, the born superhighway transportation controls the strategy, passing the information to release the sub- system, the circular circulates the medium vehicle, realization to the valid control that the superhighway transportation flow, thus raise the superhighway service level and go through the ability.This text point research direction include, belonging to the video frequency surveillance system of the information collections;The foundation- data that guarantees that the whole system function circulates normally delivers the system;The core of the distribute type supervision system controls parts of ITSs intelligence transportation control system, and the distribute type supervision system and customers can see to turn the electronics map operation interface.The superhighway video frequency surveillance system divides many classes management structure to carry on the management, the entry-level toll station imitates the video frequency picture to make use of the WDM or technique of FDMs, delivering 32 roads,64 roads or more video frequency signals of roadses on the single fiber optic of 芯 , carrying out the toll station video frequency surveillance picture concentration up spread the function that the superior manages the organization;But the second class and x-rated organization video frequency picture deliver to then adopt the video frequency picture compression technique, becoming the video frequency picture conversion the numerical signal deliver the system to carry on the picture transmission through a fiber-optic numeral.The supervision data delivers the system, is carry out the distribute type supervision system function of foundation, the synchronously fiber-optic numeral of SDH of the high bandwidth that the superhighway data delivers the adoption independence delivers the system, the whole superhighway network becomes namely an overlays all superhighways of data deliver the network, for the distribute type the supervision system provide the data, video frequency, the speech integral whole toturn to connect to go into, synchronous clock of correspondence of whole network with the total center descend the synchronous clock signal that spread for basis, keep the whole net to deliver the clock synchronous, the accuracy, accuracy that the assurance data deliver, on this foundation, the ATM framework net adoption wreath the net mix with the structure, arbitrarily some network break to connect, network would quickly afresh road from, thus guaranteed the network dependable sex of the conjunction.The ITS intelligence transportation control the system to manage forerunner of information technique, the principle integration become an organic whole, pass the logarithms according to integrate and analyze, born reasonable of control project, make use of the global satellite of the GIS geography information system and GPSs fixed position system, solid hour, accurate will induce the service information to deliver to circulate in of vehicle, the smooth superhighway car flow, exaltation service level.The distribute type supervision system and customers can see to turn to operate the interface to mainly be is part of by the control and show that the part constitute, among them controling the part adoption PowerBuilder to carry on the development, including the parts, such as the equipments control, the electronics map manifestation and the data search...etc.;Show the part namely the electronics map, adopt the Maplnfo geography information system software to carry on the development, mainly include the manifestation of the superhighway network and supervise and control the equipments to distribute along with the line, solid hour of the manifestation superhighway luck the camp circumstance, each supervision data of equipments collect and release, and supervise and control movement appearance etc. of the equipments.
