Abstract

Performance data of components of a construction machine is measured by the steps of automatically operating the component mounted to the construction machine so as to satisfy one of a plurality of measurement conditions which are preliminarily set, automatically measuring performance data of the component which is preliminarily set under the above automatically operated state, and successively performing the same steps as those defined above with respect to remaining measurement conditions other than the above-mentioned one measurement condition, thus measuring the performance data of the component with one or more than one measurement conditions.

Claims

1. A method of measuring performance data of a component of a construction machine comprising the steps of:

automatically operating the components mounted to the construction machine so as to satisfy one of a plurality of measurement conditions which are preliminarily set;

automatically measuring performance data of the components under the above automatically operated state; and

successively performing the same steps as those defined above with respect to remaining measurement conditions other than said one measurement condition thereby to measure the performance data of the components with one or more than one measurement conditions.

2. A method of measuring performance data of a component of a construction machine according to claim 1, wherein the measured performance data is sent to a remote place apart from the construction machine and an abnormal condition is displayed on the remote place at a time when the measured performance data is different from a normal performance data.

3. A method of measuring performance data of a component of a construction machine according to claim 1, wherein the measured data of components of one or more than one construction machines are sent to a remote place every one construction machine and the measured performance data of the components of the respective construction machines are totally processed and stored in the remote place.

4. An apparatus for measuring performance data of a component of a construction machine comprising:

means for detecting performance data of components mounted to the construction machine;

means for storing plural sets of measurement signals and control signals for realizing measurement conditions corresponding to the plural sets of measurement signals;

control means for outputting automatically successively, to the components, a set of measurement signals and control signals creating states for satisfying the measurement conditions corresponding to the set of the measurement signals with reference to the means for storing, to obtain performance data, and successively performing the same operation with respect to the remaining sets of measurement signals and control signals, when measurement starting signal is inputted into the control means; and

means for inputting the measurement starting signal to the control means.

5. An apparatus for measuring performance data of a component of a construction machine according to claim 4, further comprising a communication means for inputting the measurement starting signal to the control means from a remote place apart from the construction machine.

6. An apparatus for measuring performance data of a component of a construction machine according to claim 4, further comprising a data processing means adapted to judge to be abnormal in a case where the measured performance data differs from a correct performance data and a display means for displaying a fact of the abnormal condition when judged as being abnormal.

7. An apparatus for measuring performance data of a component of a construction machine according to claim 4, further comprising:

a communication means for transmitting and receiving the measured performance data to and from a remote place apart from the construction machine;

a data processing means for processing the performance data received by the communication means to a form to be displayed;

means for displaying the measured performance data processed by the data processing means; and

means arranged in operative association with the data processing means and adapted to store the measured performance data.

8. An apparatus for measuring performance data of a component of a construction machine according to claim 7, further comprising a data processing means adapted to judge to be abnormal in a case where the measured performance data differs from a correct performance data and a display means for displaying a fact of the abnormal condition when judged as being abnormal.

9. An apparatus for measuring performance data of a component of a construction machine according to claim 7, wherein said communication means for transmitting and receiving the measured performance data to and from a remote place apart from the construction machine generates transmission data in combination of the measured data and data other than the measured data such as vehicle identification number, measurement year, month, day and time, engine total working time and groups of measured conditions.

10. An apparatus for measuring performance data of a component of a construction machine according to claim 9, wherein said transmission data is used as centralized management data of the construction machine.
