中国约有500万盲人,怎样使盲人在公共场所找到饮水点方便饮水呢?我发明的盲人饮水智能引导装置,以单片机MC9S12XS128MAAi为控制核心,利用超声波传感器、电源供电模块、语音录音模块、音频放大模块以及单片机最小系统板来组成硬件电路,利用汇编语言编写控制单片机的程序,自动判断饮水装置的位置,智能引导盲人饮水。运放电路核心芯片LM386在静态工作时功耗只有40mW,为
In China, about 5 million blind people make it easier for blind people to find drinking water in public places. I invented intelligent drinking water guiding device for blind people, using MC9S12XS128MAAi as the control core, using ultrasonic sensor, power supply module, voice recording module, audio amplification Module and microcontroller system board to form the minimum hardware circuit, the use of assembly language programming control microcontroller, automatically determine the location of drinking water device, intelligent guide the blind drinking water. Op amp circuit core chip LM386 in the static work only 40mW power
