【摘要】 设计了一种由平板电脑经蓝牙转无线数传模块接力控制的遥控计分显示牌遥控系统。基于Android系统及Eclipse开发环境,编制完成了平板电脑遥控计分显示的蓝牙应用软件;采用ZC701蓝牙模块与平板电脑通信,由APC220-43无线数传模块承接计分显示牌,两者经适当的接口设计,实现了在最大约300 m的视距范围内由平板电脑控制计分显示牌显示比分、计时等功能。更多还原

【Abstract】 This paper designs a remote control system for scoring sign,which is controlled by the tablet PC via bluetooth wireless data transmission module. Based on the Android system and the Eclipse development environment,it also compiles the bluetooth application software for the tablet computer remote control display,adopts ZC701 bluetooth module and tablet computer communication and uses APC220-43 wireless data transmission module to connect the scoring sign. Both appropriate interfaces are designed to realize the its scoring and timing function within the range of about 30 m.更多还原
