摘要
给出了以凌阳16位单片机Spce061A为核心的帆板控制系统整体调节的基本原理与实现方案。该系统由电源驱动、液晶显示、调节装置、角度传感器和直流轴流风机5部分构成,由1块单片机来实现控制与显示功能。采用PWM控制技术来改变风机转速,控制风力大小,进而控制帆板转角θ,并通过角度传感器将θ转换成电信号反馈给单片机。测量分辨率精确达到2°,绝对误差不大于5°。测得θ值送给SPLC501进行显示,加外键盘以及语声光提示的功能,使得系统简洁而具有人性化的特色。
Gived the basic principle and realization scheme of board control system overall adjustment,using the sunplus 16-bit single chip Spce061A as the core of the panels.The system is maded up of five parts by the power supply,LCD display,adjusting device,angle sensor and DC axial flow fan,consisted of a single-chip computer to realize control and display functions.Using PWM control technology to change the fan speed,control the wind size,and then control panels angle θ,And finally through angle sensor to convert θ into electrical signal and feedback to MCU.Measurement resolution accurately reach 2°,absolute error is not more than 5°.The θ measured is sent to SPLC501 for display,plus external keyboard and a voice prompt light function,thus makes the system simple and with human characteristics.
