摘要
针对传统人工打分计分方式效率低的缺点,设计了基于无线通信的电子打分计分系统。系统分为打分器、计分器和上位机3部分,打分器通过人机接口实现打分、显示和存储分数,并能将存储的成绩发送给计分器;计分器收集各个打分器的成绩并汇总后上传给上位PC机;上位机通过人机界面完成各项控制操作并利用投影仪实现成绩的显示。该系统具有使用方便、统计准确、安全可靠等特点,具有良好的市场应用价值。
Aiming at the disadvantage of traditional marking and scoring method of low efficiency, an electronic marking and scoring system based on wireless communication was designed. The system includes marking unit, scoring unit and upper computer. Marking unit can realize marking, display and storage via man-machine interface, and send the results to scoring unit. Scoring unit may collect the result of each marking unit and upload to upper computer after summarizing. Upper computer may control the operation through man-machine interface, and display the results by projector. The system has the feature of easy to use, accurate statistical scores, safe and reliable, thus has good market value.
