数字驱动由于其控制算法的灵活性可以有效地提高科氏质量流量计的工作性能。针对数字驱动的启振问题,本文基于模型分析和实验仿真,提出了正负阶跃交替激励启振方法。该方法通过跟踪检测传感器自激输出信号相位进行正负阶跃交替激励,使流量管的振动幅值持续、可靠地快速增大,进而结合非线性幅值控制算法和频率估计,可使流量管启振时间大幅度地缩短,克服了传统启振方法的局限性。-Digital drive control algorithm because of its flexibility can improve t

声音是由震动所产生的, 一定频率的震动就产生了一定频率的声音。这个实验是喇叭里发出
滴答一长一短的报警声音,送出的端口是p1.2(即D2)输出如1khz,2khz、3khz变频信号报警,频率不一样发出的声音就不一样。
R54可以为10欧到100欧的电阻。
实验目的: 通过设置不同延时时间(延时时间不一样对应的频率就不一样)蜂鸣器将发出不动的声音。从而理解单片机中用位控制外围设备的方法。
