工作原理: 当人们手握住球体1准确投掷时, 手部接触到近接电容式传感器, 当球体脱离人们的手部时, 即球体被投掷后, 近接电容式传感器将“球已离手”这一信息反馈给测速仪3, 测速仪3开始计时, 当球体再次被人接住时, 近接电容式传感器将“球被接住” 这一信息反馈给测速仪3, 测速仪3经过分析后将结果通过无线发射器6以无线信号的方式发射出去,北京翻译公司 显示屏5上的无线接收器7接收到无线发射器6发射的信号, 经过数据转换后, 将结果显示在显示屏5上。

Working principle: when people hold the sphere 1 in hands to throw accurately, hands touch the approach capacitive sensor; when the sphere moves off the hands of the people, that is the sphere is thrown away, the approach capacitive sensor feed backs the message of sphere moving off hands to the velocity measuring device 3 which begins to count time; when the sphere is caught by people again, the approach capacitive sensor feed backs the message of sphere having been caught to the velocity measuring device 3 which emits results in a wireless signals mode by the wireless emitter 6 after analysis, and a wireless receiver 7 on the display screen 5 receives signals emitted by the wireless emitter 6, then converts the data, and displays results on the display screen 5.
