摘　　要：帆板控制系统主要是由AT89S52单片机、角度传感器、AD转换、键盘电路、显示电路及声光提示等电路组成。角度传感器采用型号为WDD354D的精密导电塑料电位器,其功能是把角度机械位移量转换成电信号。AD转换电路用的是具有12位分辨率的TLC2543,该芯片将角度传感器输出的模拟信号转换成数字信号,单片机采集数字信号对帆板系统电路进行控制。键盘电路由4*4矩阵键盘组成,用于调节风扇风力大小和帆板转角。用LCD12864作为显示器,来显示帆板的转角,显示分辨力达到0.1度。风扇由直流电机控制,对转速进行调节从而使帆板的转动角度在7-15cm范围内可以精确调节。The panel control system is consist of AT89S52, angle sensor, ADC, keyboard circuit, displaying part and sound and fight alarming circuit, ere.The WDD354D, a precision conductive plastic potentiometer which can be used as angle sensor, it can convert mechanical displacement into electric signal.The AD converting circuit is used with 12-bit resolution TCL2543, which can convert the analog signal from angle sensor into digital signal, the single chip collect digital signal to control panel system circuit.The keyboard circuit is consist of 4＊4 matrix keyboard, it is used to adjust the fan＇ s wind force and panel＇ sangle.The monitor using LCD12864 to display angle of panel, the resolution of panel＇ s angle could be controlled to 0.1 degrees, The fan contxolled by DC motor, regulates the speed to precisely regulate the angle in the distance from 7cm to 15cm.
