智能数字音乐盒的设计与实现
<p>随着科技的飞速发展,人们的生活节奏越来越快,多数人长期处于压力过大的状态。音乐对于调节人的心理压力来说是一种很有效的方式,因此,各式各样的音乐盒开始普及。由于容量大、操作方便、价格便宜等优点,数字音乐盒逐渐成为人们的首选。这里以电子技术为基础,设计了一款数字音乐盒。它以单片机为核心,主要由外围控制电路、外接电路、发声电路、电源电路等组成整个系统。音乐的播放可用按键或者红外遥控器实现,同时还可
基于神经网络PID液压驱动变距控制的研究.rar
在风机组整体技术不断进步的今天，变距型风机以其风能利用率高、启动性能与制动性能好和机组脱网时不需经历突甩负载过程等优点，越来越受到人们的青睐。本课对变距型风机核心技术之一的变距系统进行理论分析及仿真研究，为变距控制提供参考。本文主要作了如下工作： 第一，在查阅大量资料的基础上，通过推导得出了SUT-1000风机组变距驱动力矩的计算方法与计算公式。并根据所得变距力矩计算公式和叶片厂商提供的叶片参数数
