Design And Implementation Of Secret Key And Card Issuance Subsystem For Agricultural Irrigation And Drainage

Agricultural irrigation and drainage measurement and management system is an integrated information system to carry on electronic and information management to the main business of IC card and electricity meter using in irrigation power consumption based on the modern computer network communication technology, which is the technology basis and important guarantee of "every well is electrified and every family has the card". Secret key system and card issuance system is the core part of the agricultural irrigation and drainage management system, the development of which ensures the smooth and safe operation of the whole agricultural irrigation and drainage system.This article analyzes the design approach, system overall architecture and operation method of the secret key and card issuance system for agricultural irrigation and drainage, elaborates the system safety and reliability in detail, and explains the functional design, workflow design, interface and view design, and so on. The article also demonstrates the working detail of the issuance process of the various secret key card, tool card and user card issued from the system.The system developed by this article has already been completed, which has been applied successfully by the Hebei Province agricultural irrigation and drainage measurement system for more than two years, and adopted by the agricultural department of Electric Power Company of Henan Province to use in the Henan agricultural irrigation and drainage measurement system for more than one year.The author mainly carried out the following aspects of work: 1,Complete the status analysis of Hebei province agricultural charging system and its electricity meter, electricity meter card and card secret key application, analyze the problems in the development of current charging system together with the project team and complete the demand analysis of intelligent CPU card meter using by the Hebei province agricultural irrigation.2,After understanding the detailed requirements, the author complete the conceptual design of non-contact CPU card meter of Hebei Province agricultural irrigation and drainage, upgrading design of the new charging system, design of secret key and card issuance system, design of new non-contact CPU card intelligent electricity meter and design of new electronic meter reading device3,Complete the codes and standards of CPU card.4,Complete the codes and standards of secret key and card issuance system, demonstrate the feasibility of the design, and complete the process design of demand analysis, outline design, detailed design and software core functions (secret key distribution and download functions).5,Analyze deeply the security threat facing the agricultural irrigation secret key and card issuance system in the future.
