Abstract
A system and a method are provided for monitoring an exhaust gas purification system that is functionally connected to an emission source. An emission sensor acquires an emission signal that indicates emissions of the emission source on the exiting from the exhaust gas purification system. In addition, measurement signals that are each related to the exhaust gas purification system are acquired by a plurality of further sensors. A process state of the exhaust gas purification system is determined based on the measurement signals of the further sensors. Then, the emission signal and the process state are assessed with respect to an anomaly in each case. A compliant emission state, which indicates a correct functionality of the exhaust gas purification system, is determined and output when no anomaly of the emission signal is present or when an anomaly of the emission signal is present while at the same time no anomaly of the process state is determined or the anomaly of the emission signal satisfies an exception condition.
