Abstract

An operation supervision system for airplanes with a plurality of measuring feelers, which comprises means for transforming the measuring values into the form of electrical output signals. Indication devices are coordinated to and are operable by the electrical output signals. Norming members follow the measuring feelers. A multiplex sender is operatively connected with the norming members, and senses cyclically the measuring values normed to standard signals and fed to an analog to digital converter. A multiplex receiver is connected with the output of the analog to digital converter by means of a transmission conduit, and quasi-analog electroluminescent display means are provided to which the multiplex receiver divides the measuring values.

Claims

1. An operation supervision system for airplanes, comprising a plurality of measuring feelers, including means for transforming measuring values into the form of electrical output signals, norming members following and coordinated to said measuring feelers, respectively, a multiplex sender operatively connected with said norming members, an analog to digital converter connected to said multiplex sender, the latter cyclically sensing the measuring values normed to standard signals and fed to said analog to digital converter, a multiplex receiver connected with the output of said analog to digital converter by means of a transmission conduit, and quasi-analog electroluminescent display means coordinated to said multiplex receiver such that the latter divides said measuring values.

2. The operation supervision system, as set forth in claim 1, whiCh includes numerical indication devices in addition to said quasi-analog electroluminescent display means.

3. The operation supervision system, as set forth in claim 1, further comprising an adjustment circuit connected to an output of said multiplex sender and to the output of said analog to digital converter, and said multiplex sender receives and emits additional, digital measuring values and is arranged behind said analog to digital converter, said adjustment circuit in the output signal succession of said analog to digital converter.

4. The operation supervision system, as set forth in claim 1, wherein said multiplex sender and said analog to digital converter are disposed in the vicinity of the measuring feelers, and said multiplex receiver is disposed in the vicinity of said display means.

5. The operation supervision system, as set forth in claim 1, wherein said multiplex sender and said multiplex receiver are formed as time-multiplex devices.

6. The operation supervision system, as set forth in claim 4, which includes storage members coordinated to said display means, which retain the measuring values between successive sensings.

7. The operation supervision system, as set forth in claim 1, wherein said quasi-analog electroluminescent display means have a plurality of electrically excitable electroluminescent light cells disposed in a band-shaped succession, semiconductor switching elements selectrively operable by means of the arriving measuring values, and said light cells being excitable by means of said semiconductor switching elements.

8. The operation supervision system, as set forth in claim 1, which includes at least one digital counter disposed between said multiplex sender and said multiplex receiver.

9. The operation supervision system, as set forth in claim 8, wherein said counter combines predetermined combinations of measuring values to substitutes.

10. The operation supervision system, as set forth in claim 8, which includes an alarm device connected to said counter, said alarm to be adapted to be operated, if predetermined measuring values or measuring value combinations surpass a pre-set tolerance.

11. The operation supervision system, as set forth in claim 8, which includes means for indicating predetermined measuring values by said counter only upon reaching present critical limit values.

12. The operation supervision system, as set forth in claim 8, which includes means for supervision of a plurality of drive means, and a particular drive means counter is coordinated to each drive means.

13. The operation supervision system, as set forth in claim 12, which includes a central digital counter which combines predetermined output values of said individual drive means counters to substitutes.

14. The operation supervision system, as set forth in claim 8, which includes a registration device connected with said counter, which registration device indicates predetermined output values of said counter.
