Abstract

A remote measuring system includes a test apparatus connected to a sensor for testing an object, a communication unit, and a remoteoperating unit. Control signals may be sent from this operating unit to the communication unit to operate the test apparatus. A data processing unit performs a compression process of a first flow of test data emanating from the test apparatus and sends a second flow of test data to the operating unit. The data processing unit performs a quantisation process, which may be controlled through control signals at the operating unit. A remotely located expert may thus receive a direct and qualified impression of the procedure and the inspection results and give advice on correct procedures or on changing the manner of the recording. By obtaining support from experts, time is saved and the transfer of know-how and the use of experts is improved.

Claims

1. A remote measuring system, comprising

At least one test apparatus connected to at least one sensor;

At least one communication unit; and

At least one operating unit;

wherein the operating unit is adapted such that it may send control signals for the operation of the test apparatus to the communication unit;

wherein the communication unit is adapted such that it may receive a first flow of test data from the test apparatus by compressing the first flow of test data of a data processing unit and send a second flow of test data to the operating unit; and

wherein the data processing unit is adapted such that it may quantise the second flow of test data and adapt to the available data transmission band width between the communication unit and the operating unit, wherein the quantisation may be controlled by control signals at the operating unit.

2. The remote measuring system in accordance with claim 1, wherein the first flow of test data contains graphic data.

3. The remote measuring system in accordance with claim 2, wherein the graphic data comprise illustrations of test results and status data of the test appliance.

4. The remote measuring system in accordance with claim 3, wherein the test apparatus is adapted such that it may generate graphic data for a screen for the presentation of test results and the first flow of test data represents the contents of the screen of the test apparatus.

5. The remote measuring system in accordance with claim 4, wherein the first flow of test data and the second flow of test data comprise graphic data on a Remote Framebuffer Protocol basis.

6. The remote measuring system in accordance with claim 5, wherein the data processing unit is adapted such that, in response to control signals from the operating unit, only a part of the image represented by the graphic data is processed and the remaining part of the image is filtered out.

7. The remote measuring system in accordance with claim 6, wherein the data processing unit is adapted such that, in the quantisation process it reduces the refresh rate or the sharpness of the details of the second flow of test data.

8. The remote measuring system in accordance with claim 7, wherein the data processing unit is adapted such that it may reduce the refresh rate or the sharpness of the details of the second flow of test data when so instructed by the control signals from the operating unit.

9. The remote measuring system in accordance with claim 8, wherein the communication unit and the operating unit are coupled together by means of an ISDN line.

10. The remote measuring system in accordance with claim 9, wherein the communication unit and the operating unit are adapted such that they send a flow of communication data from the operating unit to the communication unit and reproduce this at the communication unit.

15. The remote measuring system in accordance with claim 1, wherein the sensor is associated with testing an aircraft.

11. A method for conducting a test process on a remote object, comprising the following steps:

Sending control signals to operate a test apparatus from an operating unit to a communication unit connected to the said test apparatus;

Sending a first flow of test data to the communication unit;

Carrying out a quantisation of the first flow of test data in a data processing unit in the communication unit so as to receive a second flow of test data; and

Sending the second flow of test data from the communication unit to the operating unit.

12. The method in accordance with claim 11, further comprising:

Sending control signals from the communication unit to the test apparatus for the adjustment of the test apparatus.

13. The method in accordance with claim 12, further comprising:

Bi-directionally transmitting communication data between the operating unit and the communication unit; and

Reproducing the communication data.

14. The method in accordance with claim 13, further comprising:

Digitizing the first flow of test data.
