초록 ▼

A continuous emission monitoring system for a manufacturing plant (10) includes a control system (16) which has associated therewith a virtual sensor network (18). The network (18) is a predictive network that receives as inputs both control values to the plant (10) and also sensor values. The network (18) is then operable to map the inputs through a stored representation of the plant (10) to output a predicted pollutant sensor level. This predicted pollutant sensor level is essentially the prediction of an actual pollutant sensor level that can be measured by a pollutant sensor (14). The network (18) therefore is a substitute for the pollutant sensor (14), thus providing a virtual sensor. The sensor values from the plant (10) are first processed through a sensor validation system (22). The sensor validation system (22) is operable to determine which of the sensors falls outside of acceptable limits and then substitutes therefor a predicted output, such that the inputs to the virtual sensor network (18) are within acceptable limits.

대표청구항 ▼

A method for monitoring select output parameters in a manufacturing plant that are generated as a byproduct of the operation of the plant, the manufacturing plant having controls operating in response to received control values to alter the operation of the plant, and sensors to measure the operating parameters of the plant and output associated sensor values, comprising the steps of: determining at least once the level of the select output parameters output by the plant and the associated control values to the plant in addition to the associated sensor values, the step of determining at least once utilizing a predetermined determination process; measuring on a substantially frequent basis the control values to the plant and the sensor values output by the sensors; storing a representation of the plant in association with the determination process in a virtual sensor predictive network having as an output a predicted select output parameter level that corresponds to the actual select output parameter level determined by the determination process to be output by the manufacturing plant, the control values of the plant and the sensor values of the plant comprising inputs to the virtual sensor predictive network, the stored representation learned from the determined output parameter level by the determination process, the control values and the sensor values, the virtual sensor predictive network operable to be trained upon the determined level of the select output parameters, the measured control values and the sensor values to generate the stored representation; and generating an error when the predicted output parameter level exceeds a predetermined threshold.
