Information may be transferred to the display unit 300 to be outputted.

Specifically, the controller 200 may update the resolution data 220 based on the information of the solution selected and used to solve the problem according to the cause of the abnormality. The controller 200 assigns a weight to a solution used to solve an abnormal cause among a plurality of stored solutions, so that when the same abnormal cause is derived, the user has a solution with a history used for solving the same cause.

The user executes the control method of the selective catalytic reduction system management apparatus.

The abnormality information of the selective catalytic reduction system is detected to determine whether an abnormality has occurred (S100). That is, abnormality information is detected whether there is a problem in the operation of the selective catalytic reduction system, and it is determined whether the detected abnormality information value is in an abnormal state.

When it is determined that there is an abnormality through the abnormality information, a candidate for the cause of the abnormality that may cause such abnormal information is derived according to the detected abnormal information (S200). That is, a plurality of abnormal cause candidates may be derived which may cause such two impression information according to one abnormality information. Therefore, the control unit may derive a plurality of candidate causes of the abnormality according to the abnormality information. That is, to solve the problems caused by various abnormal causes effectively.

In addition, the control unit calculates the probability of occurrence of an abnormality for each abnormal cause candidate through a fuzzy diagnosis algorithm for each candidate of various abnormal causes (S300).

Thus, through the probability calculated through the algorithm, the most likely cause of the cause candidates are discharged (S400). That is, the cause of the abnormality matched with the highest probability with the currently detected abnormal information is derived. For example, the user may be notified of the most probable cause of abnormality by using a display unit.

It proposes a solution to solve the derived abnormal causes (S500). In detail, the controller presents the user with a solution that is most suitably matched to solve the cause of the problem derived from the stored DB. In this case, the solution proposed initially may be selected and presented based on a predetermined default value.

It is determined whether the derived abnormal cause is solved (S600). In this case, when the derived abnormal cause is not solved, it may be performed by selecting another solution among a plurality of proposed solutions (S500).

The controller assigns a weight to a solution for solving the derived abnormal cause (S700). That is, when the solution selected to solve the abnormal cause derived from the plurality of solutions is later derived as the same cause, the above-described solution is presented (S500) so that it can be output to the display unit.

In order to solve the derived abnormal cause, it is determined whether the part is replaced (S800).

If it is determined that the part is replaced, the information of the replaced part is stored (S900). That is, the parts information of the selective catalytic reduction system is updated. In detail, the controller may receive the part information from the user or calculate a replacement date of the replaced part through a timer included in the selective catalytic reduction system and store the replacement date.

If it is determined that there is no abnormality through the abnormality information, the user receives a search word for the abnormality information of the selective catalytic reduction system (S250). Specifically, the user may search for abnormality information even when the selective catalytic reduction system is in normal operation.

According to the inputted abnormality information, the abnormality symptom that may appear when the abnormality information is detected is output to the display unit in detail so that the user can recognize it (S260).

In addition, the user guides a solution for resolving the input abnormality information (S270).

When the user outputs any one of the abnormality information, the cause of the abnormality, and the solution to the display unit, the user may provide the image information together.

With such a configuration, the control method of the selective catalytic reduction system management apparatus according to the embodiment of the present invention can effectively solve this problem as well as checking the abnormal information regardless of the user's expert knowledge and skill.

In addition, regardless of whether the abnormality information is detected, the user may search for the abnormality of the selective catalytic reduction system and effectively recognize and learn the symptom appearing accordingly.

Although the embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art to which the present invention pertains can understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential features. will be.
