An information collection and display system is provided, in which a data generation device that generates site data and a transaction data accumulation unit that stores the site data are connected. The system includes an association data accumulation unit storing association data which defines an association of each of multiple pieces of information included in the site data; an association data search unit which searches for second information associated with first information included in the pieces of information, on the basis of the association data; and a user interface that displays a connection relation of the pieces of information associated by the association data. The association data search unit searches for the second information associated with the first information displayed on the user interface and displays the first information and the second information on the user interface with the connection relation of the pieces of information.

An exhaust gas purifying system includes a differential pressure detector that detects a differential pressure between an inlet/outlet of a filter, a flow rate detector that detects a flow rate of exhaust gas in the filter, a differential based-deposition-amount calculator that calculates a differential-based deposition amount of particulate matters in the filter based on detection results of the differential pressure detector and the flow rate detector, a regeneration temperature setting unit that sets a regeneration processing temperature of the filter based on the calculated differential-based deposition amount, and a regeneration processing unit that performs a regeneration processing of the filter based on the set regeneration processing temperature. The regeneration temperature setting unit sets a first regeneration processing temperature at a start of the regeneration processing and a second regeneration processing temperature higher than the first regeneration processing temperature when the differential-based deposition amount falls at or below a predetermined threshold.
