单片机技术在电气传动系统中的应用策略研究
<p>当前科学技术的不断发展,单片机技术也正向成熟方向发展。文章对单片机进行概述,并对其种类和结构进行分析,其控制模块、寄存模块和运算模块构建了完整的操作体系,系统在运行过程中,对数据信息进行逻辑性运算,具有数据信息传输的稳定性和高效性。在电气传动系统中应用时,通过控制模块、软件算法模块和运算模块,提升电气传动系统的操控精度和工作效率。</p><p>At present, with the con
基于FPGA和单片机的逻辑分析系统研究
<p>在电子产品设计中,往往需要借助逻辑分析仪来观测数据波形,分析其中的逻辑关系。但传统的逻辑分析仪不仅价格昂贵,而且信号的分析还需要手动完成,花费大量时间和精力,效率低下。介绍了一种可编程逻辑分析系统的设计方案,利用FPGA设计可选位宽数据采集与存储器的接口,通过单片机控制,将采集的数据从串口中传送到PC机上,编写基于VC的人机界面的分析程序,实现波形存储、显示、分析功能。实验表明:该系统具有成
Modbus通信通讯教程(详细)
<p>自动控制系统的各种设备，相互之间的通信及资料交换是非常重要的基本功能之一。早期通信方式是使用串行式硬件架构，然后定义通信步骤及资料格式等基本通信规格，也就是通信协议（Communication Protocol）。外部计算机依据此通信协议即可与该自控设备读取或写入资料。也可以看做读取该控制设备所控制的结果，写入一些控制命令要求该控制设备执行所指定的功能。</p><p>PLC（Programm
