Abstract
A line monitoring apparatus includes a state change detection number counter configured to count a state change detection number that is a number of a state change in a line being detected by a first type detecting process; and a state change frequency determiner configured to determine whether or not the state change detection number counted per a predetermined unit time exceeds a predetermined threshold value, wherein when the state change detection number counted per the unit time exceeds the threshold value, the detecting process of detecting a state change in the line is changed from the first type detecting process to a second type detecting process.
