Research And Implementation Of The Key Technologies Of The Multi-channel Auto/Manual Fax Send And Receive System

Since the fax service in the public switched telephone network has been opened andapplied,fax communication has been vigorously developing.The fax has become one of the mainmeans of transmitting information.In this paper, according to the research content,from a practical point of view,Firstintroduced the relevant fax technology development status at home and abroad.Secondly, the keytechnologies of the system are discussed in detail.Finally, For the disadvantages of the thetraditional fax mode,that based on the PSTN telephone network, the paper has put forward afeasible solution,discussed the system design thought and the system composition structure,givedthe system realization and system test scheme and results.The paper mainly study and solve the problems of traditional fax job completely rely onmanual operation, slow aging, error-prone and labor intensity.Designed and implemented thesystem software and hardware.Software design of the system and proposes a rule designmethod,The method adopts the object-oriented design thought,The fax rules has niqueness,Usinguniform design,The system of rules depends only on the program.Proposes a multiple thread linechain of responsibility work mode,The model combines the lines and the chain of responsibilityof job characteristics,The control program through the decomposition step, constructingmulti-thread synchronization operation and the asynchronous call method. Put forward a kind ofobjects launched algorithm under complex conditions.Before drawing lessons from backstagework mode features,Structuring the system object introduced algorithm, and the algorithm isformalized description and analysis.System hardware design and implementation of a fax groupcontroller, is used to realize the multi-channel transceiver fax.Above the methods, the utility model design philosophy,the fax group transceiver controllerhas been produced. Using the mature C#programming languages, using the principle ofdistributed and object-oriented programming ideas,achieved the system software.The hardwareand software combination achieved the realization of multi-channel A/M fax transceiver system.Through the practical application of the system test.Within a cohort of fax object Importorder, clear process, multiple concurrent without mutual interference, the user feel good,thesystem is running normally and excellent performance for long term. This paper studies verifiedthe validity and feasibility of technical achievements.
