    Abstract: PROBLEM TO BE SOLVED: To enable a plurality of process plants associated with different business entities to share a remotely situated data processing facility by a data processing system and method for use with a process control system. SOLUTION: The data processing facility includes a cluster of redundant servers that are communicatively coupled via a local network. Each of the redundant servers is adapted to acquire and process data received from a plurality of process plants. The data processing facility also includes a plurality of redundant data historians that are communicatively coupled to each other and to the cluster of redundant servers for storage of process data and analysis results. Each of the plurality of process plants includes internet-enabled field devices, internet-enabled field device interfaces, and/or internet-enabled data concentration nodes that send and receive information related to the data processing facility by using the Internet.

    Abstract: PROBLEM TO BE SOLVED: To solve the problem that a control system utilizing a low speed scan cycle is unable to compensate for high frequency process variations which have a duration less than the round-trip communications time between the controller developing the compensating control signal and the measurement device. SOLUTION: A measurement device measures a process variable at a relatively high frequency and sends a subset of the measured data (eg. the low frequency data) to a standard controller. The standard controller generates a control signal to control the measured process parameter in any known manner. The modeling routine analyzes the high frequency data and develops a mathematical model of the high frequency noise within the process variable. The resulting mathematical model may then be used by a compensation routine to alter the control signal produced by the controller before that control signal is delivered to or used by the device being controlled.

    解决方案:测量设备以相对高的频率测量过程变量,并将测量数据的一部分(例如,低频数据)发送到标准控制器。 标准控制器以任何已知的方式产生控制信号以控制测量的过程参数。 建模程序分析高频数据,并开发过程变量内高频噪声的数学模型。 然后,所得到的数学模型可以由补偿程序使用,以在该控制信号被传送到被控制的设备或由被控制的设备使用之前改变由控制器产生的控制信号。 版权所有(C)2010,JPO&INPIT
