作品简介:该作品与配备的多个从机构成一个计分体系,可以通过总机器读取从机器的分值.每个计分员在手上的计分从机器输入分数,则无需人手统计,就能在总机器的液晶屏上看到各位记分员给的分数. 支持多个从机同时通过USB线连接到总机.由于USB连接市场上能方便的购买,所以使用USB连接线构建计分体系. 作品作用:在各种文艺活动中的计分环节上,能方便的为计分员统计分数. -Works Introduction: the work and is equipped with a number from the body into a scoring system, the machine can read the total scores from the machine. Each scoring in the hands of the points from the machine enter the scores, you do not need manpower statistics can be in the overall machine s LCD screen to see all the scores to the scorekeeper. support multiple machines at the same time from the USB line to connect to the switchboard. USB connection as a result of the market can make it easier to buy, so use the USB cable to build a scoring system. work roles: in a variety of cultural activities in the scoring areas, can make it easier for Members of statistical scores points.

This code can detect the insertion of USB device in the system
