全自动可遥控旗帜升降系统以AVR单片机为核心，由PWM对电机进行变频调速，高精度光电编码器测速，闭环式电路控制。能够利用按键输入相应的指令控制旗帜的升降，还可以实现在特定位置停留的功能。利用LCD可以显示旗帜的实时高度和相应的控制命令，用LED指示旗帜是否处于半旗状态，具有语音提示报警功能，并可利用无线模块实现遥控功能，准确均匀地实现旗帜的升降(Automatic landing system can be remote-controlled flag to AVR microcontroller core of the PWM VVVF motor, high-precision optical encoder gun, closed-loop control circuit. Enter the appropriate button to take advantage of the command control of the rise and fall of the flag, but also can stay in the function of a specific location. LCD can display the banner of the use of real-time high and the corresponding control command, the LED is directed at the flag half-mast, and alarm functions with voice prompts, and the use of wireless remote control function module, to achieve uniform and accurate take-off and landing flag)

RMAA
电子爱好者们经常希望测试自己的音频设备如声卡、碟机、功放、音箱等的性能指标，却苦于没有价格高昂的专业测试设备而无从下手，设计制作时也无法进行必要的测试指导。有些CD碟提供了测试信号，如著名的“雨果发烧碟（一）”、“My Disk”等，《无线电》也曾推出音频测试CD。但CD信号的精度有限，而且没有操作系统的配合，测量、记录和分析都很不方便。(Electronic fans often want to test their audio devices such as sound cards, CD, amplifier, speakers and other performance indicators, but have no specialized test equipment without the high price the start, can not carry out the necessary tests to guide the design of production. Some CD discs provide a test signal, such as the famous Hugo Audiophile CD (a) , My Disk and so on, Radio has launched an audio test CD. CD signal but the accuracy is limited, and there is no tie, measurement, recording and analysis of the operating system is very inconvenient.)
