Description

用于运行调节驱动装置的方法
技术领域
本发明涉及一种用于运行由压力介质运行的调节驱动装置的方法，该调节驱动装置借助于一个位置调节器控制。
背景技术
在自动化技术中需要直线驱动装置和旋转驱动装置，它们相互区别在于操纵调节机构的方式。不同的驱动类型通过位置调节器实现不同的控制。因此在运行由压力介质运行的调节驱动装置的情况中通过手动地输入参数确定，直线驱动装置或者旋转驱动装置是否与位置调节器连接。这个操作是潜藏误差的并且在错误输入的情况中会导致调节驱动装置和/或调节机构的损坏。
发明内容
因此本发明的目的是，进一步改善已知的由压力介质运行的调节驱动装置的运行，使得自主地识别驱动类型。
按本发明，该目的用权利要求1的措施解决。本发明的有利的实施形式在从属权利要求中描述。
本发明从由压力介质运行的调节驱动装置出发，该调节驱动装置与位置调节器连接并且由其控制，其中调节驱动装置的输出端的位置被通报到位置调节器中。
按本发明，调节驱动装置为了确定驱动类型在运行期间用恒定的压力介质流加载并且在此记录应答的位置关于时间的驱动装置特定的特征曲线。紧接着确定的特征曲线与预定的样本特征曲线比较。由驱动装置特定的特征曲线与样本特征曲线的偏差或一致的程度推断出驱动类型。
旋转驱动装置的特征曲线的形状与直线驱动装置的特征曲线的形状显著不同。通过与预定的样本特征曲线比较按简单的方式呈现区别。
按本发明的另一特征设定，预定的样本特征曲线通过两个待区分的驱动类型之一的已知的特征曲线的理想化确定。在观察的驱动类型与基于样本特征曲线的驱动类型一致时，特征曲线的一致程度很高。只要观察的调节驱动装置与基于样本特征曲线的驱动类型不同，那么该调节驱动装置的特征曲线与样本特征曲线显著不同。
按本发明的另一特征设定，观察的调节驱动装置的特征曲线与样本特征曲线的一致的程度通过互相关性确定。
附图说明
下面借助于实施例详细解释本发明的其他详情和优点。为此必要的附图如下：
图1显示在过程阀上由压力介质运行的调节驱动装置的视图。
具体实施方式
按图1未进一步描述的工艺设备的一个局部表示的管道1中安装一个过程阀2。过程阀2在其内部具有一个与阀座3共同作用的关闭体4，用于控制流过的过程介质5的量。关闭体4由一个调节驱动装置6通过一个升降杆7直线地操纵。调节驱动装置6通过一个轭架8与过程阀2连接。一个位置调节器9设置在轭架8上。升降杆7的升降通过一个位置接收器10报告给位置调节器9。探测的升降与在调节单元18中的通过通信接口11输送的额定值比较并且调节驱动装置6根据确定的调节偏差进行控制。位置调节器9的调节单元18具有一个I/P转换器，用于将电的调节偏差转换成相当的控制压力。调节单元18的I/P转换器通过一个压力介质输送件19与调节驱动装置6连接。
在运行期间调节驱动装置6为了确定驱动类型借助于位置调节器9用恒定的压力介质流加载。由此升降杆7运动并且该运动用位置接收器10报告到位置调节器9中。在位置调节器9中记录升降杆7的应答的位置关于时间的驱动装置特定的特征曲线。
记录的特征曲线与预定的样本特征曲线比较。由驱动装置特定的特征曲线与样本特征曲线的偏差或一致的程度推断出驱动类型。
y1＝x1(l)其中l＝0...(n-1)
y值与用于直线驱动装置的理想函数比较。互相关性通过系数 c l = Σ k = 0 n - 1 y k z k + 1 确定。
另外通过观察的调节驱动装置的特征曲线与样本特征曲线的比较，通过互相关性在安装时识别误差，它们显示该特征曲线相对于样本特征曲线移动确定的固定量(偏移量)。有利地该误差用与设置用于识别驱动类型一样的措施识别。因此改善绝对的位移测量的结果。
