本文简述一个用微机实现的计算机选举计票网络系统，网络选用了星型拓扑结构，各投票箱端是一种智能化的OMR设备，网上的数据传输采用后台、并发、全双工方式进行。即充分保证了数据传输的实时、可靠性，又保留了前台应用软件在DOS环境下开发、运行的兼容性。 This paper outlines a computer network of computer counting and counting system which is realized by computer. The network uses the star topology. Each terminal of the ballot box is an intelligent OMR device. The data transmission in the network is carried out in the background, concurrent and full-duplex . That is fully guaranteed the real-time data transmission, reliability, but also retained the foreground application software development and operation in the DOS environment, compatibility.
