METHODS AND APPARATUS TO VALIDATE VALVE POSITION PARAMETERS

Methods, apparatus, and articles of manufacture to validate position parameters of a valve are disclosed. An example apparatus includes a field device, the field device further including a sensor interface to receive an unprocessed valve position parameter from a sensor and a position comparator to determine a deviation between the unprocessed valve position parameter and an interpreted valve position parameter and a valve position validator apparatus, the valve position validator apparatus further including a parameter comparator to determine if the deviation exceeds a threshold and an alertgenerator to generate an alert when the parameter comparator determines the deviation exceeds the threshold. 公开了用于验证阀的位置参数的方法、装置和制品。示例装置包括现场设备和阀位置验证器装置，现场设备进一步包括传感器接口和位置比较器，传感器接口用于从传感器接收未经处理的阀位置参数，位置比较器用于确定未经处理的阀位置参数与经解释的阀位置参数之间的偏差，阀位置验证器装置进一步包括参数比较器和警报生成器，参数比较器用于确定偏差是否超过阈值，警报发生器用于在参数比较器确定偏差超过阈值时生成警报。
