Appendix B. Advanced Topics

Appendix B.1. How Malfunctions are determined and stored

•The notes below describe how the driver parses incident reports obtained by the QIR poll.

•The driver starts at the end of the report and works its way to the top, line by line.

•Each line is inspected to see if it contains either of the following strings

“ALARM RESET"

"ALL MALFUNCTIONS CLEAR”

•If either is reported then the driver sets all the array elements to zero except those corresponding to lines of the report appearing after (and hence later in time) one of the above lines that indicates that malfunctions be set, in which case those particular malfunctions will be reported as 1’s in the Data Array.

•When either one of these two events is found the driver stops parsing the report as all prior lines predate the clear event.

•Each line is inspected for the string “MALFUN”. If it is found then ‘Event’ field in the report is inspected and the description is extracted and compared to the malfunction list provided in Appendix A.2. If a match is found the driver uses the offset value and sets the corresponding element in the Data Array to 1.

•If the string “MAFUN” is not found then the description found in the ‘Event’ field of the report is used to look up a ‘Return to Normal’ event in the table provided in Appendix A.2. If a match is found then the corresponding offset in the Data Array is set to zero.

•If the description is not recognized then it it is ignored.

Example

Only the Malfunction ‘COUS SENSOR TIMEOUT’ would have its Data Array element set to

1.All others will be set to zero. The reason is that all events above the ‘ALARM RESET’ line are considered to be prior to the reset and are thus cleared when the driver sets all the Data Array elements to zero. The timeout event occurs later and hence its malfunction is set.

When the driver uses the lookup table to see if it recognizes the event description then it compares the strings looking for an exact match. If no exact match is made then the driver uses a so-called ‘soundex’ function to see if the strings are very similar, if they are then they are considered to be matched. If a similar match is made the driver reports this in the error log.
