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 measuring gas ingredients in sampled intake and/or exhaust gas of an internal-combustion engine, the test system comprising:

a plurality of measuring devices used for measuring the gas ingredients, wherein each of the plurality of measuring devices includes a plurality of components, wherein each of the plurality of measuring devices is configured to be operable in and switched among at least first and second operational modes in which at least one of the components of the measuring device is set to operate in the first operational mode of the measuring device, and set to not operate while other of the components of the measuring device operate in the second operational mode of the measuring device, and wherein each of the plurality of measuring devices includes a local computer that calculates a measured value indicating a concentration of each ingredient in the sampled gas;

a device managing device communicably connected to the plurality of measuring devices and configured to manage the plurality of measuring devices;

a history-information acquiring unit for acquiring, for each of the plurality of measuring devices, operating history information indicating operating history including accumulating operating time of each of the plurality of components, wherein in accumulating the operating time of each of the plurality of components, the history-information acquiring unit accumulates the operating time of the component only in the operational modes for which the component is set to operate and not in the operational modes for which the component is set to not operate; and

an accepting unit for accepting setting data to set, for each of the plurality of measuring devices, predetermined operational modes, wherein the setting data indicates whether each of the plurality of components of the measuring device should operate.

2. The test system according to claim 1, wherein the history-information acquiring unit is for further acquiring operational check history information indicating operational check history of operational check.

3. The test system according to claim 1, wherein the plurality of measuring 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 for one of the plurality of components reaches lifetime of the one of the plurality of components, 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, wherein the device-managing device further includes a warning generating unit for generating a real warning when the accumulated operating time for one of the plurality of components reaches lifetime of the one of the plurality of components, and a preliminary warning when the accumulated operating time reaches a predetermined time prior to the lifetime, and wherein the accepting unit accepts setting of the lifetime and/or the predetermined time.

6. The test system according to claim 2, 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.

7. The test system according to claim 2, wherein the operational check history information includes elapsed time from completion of the last operational check.

8. The test system according to claim 6, 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.

9. The test system according to claim 6, 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.
