Research Of The Fuel Station System About Controlling Tax On The Basis Of The DIstributed Control

The distributed control system is a trend of industrial control automation at present, with the technology of the microprocessor, the technology of the computer, the development of the communication technology of the network, the role in distributed control system of the computer is more and more important.Our country is devoted to the construction of the information of national economy, with" gold bridge"," gold card", " gold tax" project for" gold series" of representative project make positive contribution to of our country national economic development with social information-based improvement of competence.The fuel dispensers of our country are mostly in dispersing the isolated state, and the oil station spread all over the urban and rural areas, Tax authority unable to grasp readymade oil sales volume and amount of money while being accurate, oil station it evades taxes to be very much serious to evade the tax of phenomenon, Cause a large amount of loss of national tax.This text is directed against the implementation of the present project of gold series" of our country and trend of the collection fuel tax, Through the collecting of a large amount of materials, the research of reading and relevant technology, Including respects, such as systematic development design method, network technology, communication technology, smart card technology and systematic software design, etc. content, designing the oil station system about controlling tax on the basis of the distributed controls .The full text divides into six chapters altogether.Chapter one Introduce the evolution of the computer control system in the industrial automation, has explained research meaning and main train of thought of a subject;Chapter two Introduce the characteristic, current situations and trends of system structure, function, development of the domestic and international distributed control system;Chapter three Discuss the concept to analyze distributed control system, overall design philosophy of the structure and system, the ones that and has recommended in the distributed control system resolve - coordinate the design method;Chapter four Accuse of the oil station system about controlling tax on the basis of the distributed controls hardware analyze and design, And has explained the relevant technology, such as network, communication, smart card, etc. in distributed control system;Chapter five Accuse of the oil station system about controlling tax on the basis of the distributed controls software analyze and design;Chapter six the design of the system has been summarized, and has looked forward to the prospect of using.
