Abstract

A device management apparatus has a display part that obtains various types of information outputted from testing devices, and erasably, switchably, or movably displays the pieces of information on a display, wherein regardless of the display of the pieces of information, the display part preferentially displays three alarm icons that are respectively for three pieces of alarm information including: sensitivity alarm information indicating a reduction in sensitivity of each of the testing devices; accumulated operating time alarm information that is alarm information on an accumulated operating time of the testing device; and inspection date/time alarm information that is information indicating approaching or passing of an inspection date/time of the testing device, and respectively have forms that are changed depending on contents indicated by the respective pieces of alarm information.

Claims

1. A test system intended to perform a test of an object, the test system comprising:

one or more testing devices used for the test; and

a device management apparatus that is communicably connected to the testing devices to manage the testing devices, and that includes a display part configured to obtain various types of information outputted from the testing devices, to erasably, switchably, or movably display the pieces of information on a display, to preferentially display three alarm icons on the display regardless of the display of the pieces of information, and to alter a form of at least one of the three icons in response to contents indicated by respective pieces of alarm information, wherein the respective pieces of alarm information include sensitivity alarm information indicating a reduction in sensitivity of each of the testing devices, accumulated operating time alarm information that is alarm information on an accumulated operating time of at least one of the testing devices, and inspection date/time alarm information that is information indicating approaching or passing of an inspection date/time of at least one of the testing devices.

2. The test system according to claim 1, configured such that

a single alarm icon display area that displays the three alarm icons as a set is provided on the display.

3. The test system according to claim 1, configured such that

when any of the alarm icons is selected and operated, a switch to a list display screen that provides a list display of alarms as a list with demarcating the alarms for each occurrence location and for each content is made;

and further, when one column on the list display screen is designated and operated, a predetermined unit schematic diagram including an generation location of an alarm is displayed, and in the schematic diagram, the alarm generation location is displayed with the location being specified.

4. The test system according to claim 1, wherein

the testing devices are measuring devices used to measure exhaust gas of an internal combustion engine.

5. A device management apparatus that is communicably connected to one or more testing devices for testing a moving body, the device management apparatus having

a display part that obtains various types of information outputted from the testing devices, and erasably, switchably, or movably displays the pieces of information on a display, wherein regardless of the display of the pieces of information, the display part preferentially displays three alarm icons that are respectively for three pieces of alarm information including sensitivity alarm information indicating a reduction in sensitivity of each of the testing devices, accumulated operating time alarm information that is alarm information on an accumulated operating time of the testing device, and inspection date/time alarm information that is information indicating approaching or passing of an inspection date/time of the testing device, and changes a form of at least one of the three icons depending on contents indicated by the respective pieces of alarm information.

6. A vehicle performance test system comprising:

a measuring device that analyzes exhaust gas to measure performance of a vehicle; and

a management apparatus that manages the measuring device, wherein the management apparatus includes

a situation data obtaining part that, as situation data, successively obtains information on an operating situation of the measuring device,

a trouble data recording part that in a case where content of the obtained situation data meets a predetermined condition, records the situation data in a memory as trouble data,

a trouble list display part that displays, among contents indicated by pieces of trouble data recorded in the trouble data recording part, at least contents related to a predetermined item on a screen in a form of a table that is demarcated so as to be able to select each of the pieces of trouble data, and

a locational information screen display part that, in response to a selection of one of the pieces of trouble data from the table, displays a locational information screen that illustrates a location associated with the measuring device where the selected one of the pieces of trouble data was obtained.

7. The vehicle performance test system according to claim 6, comprising

a monitoring screen display part that, on the screen, displays an alarm icon that lights when the trouble data recording part records trouble data.
