Abstract

According to the present invention, a test system 1 that tests a mobile body such as a vehicle, a vessel, and a plane, or an instrument used in the mobile body as an object, and is operable by switching among different operational modes, can accumulate an operating period of a component much more accurately than conventional system, and includes an accumulated operating-time calculating unit 46 for accumulating the operating time of the component, and the accumulated operating-time calculating unit 46 accumulates the operating time of the component only in the predetermined operational mode.

Claims

1. A test system for testing a mobile body such as a vehicle, a vessel or a plane, or instruments used in the mobile body as an object, and being operable switching among different operational modes, the test system comprising:

a history-information acquiring unit for acquiring operating history information indicating operating history including operating time of a component or operational check history information indicating operational check history of operational check, wherein,

in accumulating the operating time of the component, the history-information acquiring unit accumulates the operating time of the component only in the predetermined operational mode set for each component.

2. The test system according to claim 1, further comprising

one or more testing devices used for the test;

and

a device-managing device communicably connected to the testing devices, the device-managing device managing the testing devices, wherein;

the history-information acquiring unit accumulates the operating time of components of the testing devices; and

the device-managing device includes an accepting unit for accepting designation of the component and designation of the predetermined operational mode of the designated component.

3. The test system according to claim 2, wherein the testing devices are provided with the history-information acquiring unit and an accumulated operating-time storing unit for storing accumulated operating time calculated by the history-information acquiring unit.

4. The test system according to claim 1, wherein the device-managing device further includes a warning generating unit for generating a real warning when the accumulated operating time reaches lifetime of the component, and a preliminary warning when the accumulated operating time reaches a predetermined time prior to the lifetime.

5. The test system according to claim 1, further comprising

one or more testing devices used for the test;

and

a device-managing device communicably connected to the testing devices, the device-managing device managing the testing devices, wherein;

the history-information acquiring unit accumulates the operating time of components of the testing devices; and

the device-managing device includes an accepting unit for accepting designation of the component and designation of the predetermined operational mode of the designated component,

wherein the device-managing device further includes a warning generating unit for generating a real warning when the accumulated operating time reaches lifetime of the component, and a preliminary warning when the accumulated operating time reaches a predetermined time prior to the lifetime,

wherein the accepting unit accepts setting of the lifetime and/or the predetermined time.

6. The test system according to claim 2, wherein the testing devices are measuring devices used to measure exhaust gas of an internal-combustion engine.

7. The test system according to claim 1, further comprising

a display control unit displaying a setting screen for setting an instrument with operating history to be managed among the instruments constituting the test system or for setting operational check of the test system with operational check history to be managed, wherein

the history-information acquiring unit acquires operating history information indicating the operating history of the instrument set on the setting screen, or operational check history information indicating the operational check history of the operational check set on the setting screen.

8. The test system according to claim 1, wherein the operational check history information includes elapsed time from completion of the last operational check.

9. The test system according to claim 7, wherein:

the setting screen has an upper limit value input column for setting an upper limit value of the accumulated operating time of the set instrument or the elapsed time of the set operational check; and

the test system further comprising;

a time comparing unit for comparing the upper limit value set by the upper limit value input column with the accumulated operating time or elapsed time acquired by the history-information acquiring unit; and

an informing unit for informing that the accumulated operating time or the elapsed time exceeds the upper limit value.

10. The test system according to claim 7, wherein the display control unit displays the operating history information or operational check history information acquired by the history-information acquiring unit on the setting screen.
