用单片机设计pid水温传感器用什么软件仿真
你已经很轻松了 不需要做板 随便抄抄都可以过了 我还要 做板呢 自己弄吧
SW里管道设计PID文件从哪里来
pid专用软件。
随着SolidWorks布管功能在三维管道设计中的广泛应用，开发了运行于AutoCAD图形环境的专用pid，可以下载pid软件使用。
SolidWorks公司成立于1993年，由PTC公司的技术副总裁与CV公司的副总裁发起，总部位于马萨诸塞州的康克尔郡（Concord，Massachusetts）内，当初的目标是希望在每一个工程师的桌面上提供一套具有生产力的实体模型设计系统。从1995年推出之一套SolidWorks三维机械设计软件至2010年已经拥有位于全球的办事处，并经由300家经销商在全球140个国家进行销售与分销该产品。1997年，Solidworks被法国达索（Dassault Systemes）公司收购，作为达索中端主流市场的主打品牌。
通用数字PID调节器设计
PID调节器主控部分包括以下几个部分：单片机部分、A/D转换部分、D/A转换部分、稳压部分、数字输入输出部分以及串口通信部分。
D1：内部设定点信号灯
S1：内部设定点和外部设定点转换开关
D2：手动信号灯
S2：手动自动转换开关
D3：实际值X显示信号灯
D4：设定值W显示信号灯
S3：参数修改以及实际值和设定值显示转换开关
D5：超过限定值信号灯
D6：低于限定值信号灯
S4：设定值增加按钮
S5：设定值减少按钮
S6：修改手动变量按钮
S7：修改手动变量按钮
