摘要
对当前主流电子表决投票系统架构进行梳理,理论结合实际对系统存在的安全隐患进行分析归纳,找出关键原因。结合理论知识和现有系统特点,制定最优技术改进方案,暨组建环状总线通信网络结构,同时实现控制器双机热备功能。以最低成本优化了系统结构,提高了系统安全性和可靠性。同时注意改进方案带来的新问题,避免新方案带来新的不可靠因素。
This paper combs the current mainstream electronic voting system on architecture, analyzes the potential safety hazard of induction, and finds the problem and defects： Combining with the characteristics of theoretical knowledge and the existing system, it develops the optimal technical improvement scheme, to form a ring bus communication network structure and achieve double machine hot standby controller. At the lowest cost, it optimizes the structure of the system, and improves the system security and reliability. At the same time, it pays attention to solving the new problems caused by the improved scheme, avoiding a new scheme to bring new unreliable factors.
