Abstract

The invention relates to a signal display device for displaying signals on signal paths of a wiring harness, for example, which may be connected to the signal outputs of an electronic apparatus generating/receiving signals, or looped into the signal paths between a signal-generating electronic apparatus and a signal-receiving electronic apparatus. A signal to be displayed each time is measurable from a plurality, preferably all, of the signal paths, and each measured signal is fed to an evaluation unit that, for each measured signal, activates a multicolor display element based on a value of the signal, such that one of several colors may be displayed using the multicolor display element.

Claims

1. A signal display device for displaying signals on signal paths, comprising:

a signal-generating/receiving apparatus having signal outputs connectable to the device and with which a signal to be displayed each time is measurable from a plurality of the signal paths;

an evaluation unit for receiving each measured signal and which for each measured signal, the evaluation unit is operable to activate a multicolor display element based on a value of the signal; and

a multicolor display element capable of displaying one of several colors;

wherein the display of a multicolor display element in a color not allocated to an interval, indicates an exception status of the indicated signal.

2. A signal display device for displaying signals-on signal paths, comprising:

a signal-generating apparatus and a signal-receiving apparatus wherein the device is looped into the signal paths between the signal-generating apparatus and the signal-receiving apparatus, and with which a signal to be displayed each time is measurable from a plurality of the signal paths;

an evaluation unit for receiving each measured signal and which for each measured signal, the evaluation unit activates a multicolor display element based on a value of the signal; and

a multicolor display element capable of displaying one of several colors.

3. The device according to claim 2 wherein the multicolor display element is a multicolor LED.

4. The device according to claim 3, wherein the multicolor LED is activatable using the evaluation unit based on the value of the signal to be displayed, such that it is switched off or lights up in one of its basic colors or in at least one mixed color.

5. The device according to claim 3 wherein the multicolor LED is activatable such that it can light up in at least two mixed colors, wherein one mixed color is generated by a pulse width modulated activation of the portion of the multicolor LED that generates a basic color each time.

6. The device according to claim 2 that is configured such that

a maximum signal value range displayable with a multicolor display element is divided into several, equal intervals, wherein one of the displayable colors is allocated to each interval, and in which the color corresponding to the interval in which the value of the signal to be displayed lies can be displayed with a multicolor display element.

7. The device according to claim 2 configured such that a color indicated using a multicolor display element changes proportionally, and continuously, depending on the value of a signal.

8. The device according to claim 6 further comprising:

an allocation display which shows the allocation of every possible color to at least one interval.

9. The device according to claim 8 wherein the allocation display includes a number of multicolor display elements corresponding to the number of intervals, with the number of multicolor display elements indicating a color corresponding to its interval allocation, wherein aside from a multicolor display element an allocated interval is indicated.

10. The device according to claim 2 as wherein a multicolor display element is activatable in a flashing manner in at least one allocated color to indicate a signal state.

11. The device according to claim 10 wherein the flashing frequency is based on a state of the signal.

12. The device according to claim 6 that is configured such that a maximum displayable signal value range of a multicolor display element is switchable between at least two signal value ranges.

13. The device according to claim 12, that is configured such that each switchable, maximum displayable signal value range of a multicolor display element is subdivided into the same number of each equal interval.

14. The device according to claim 2 that is configured such that a signal path may be disconnected between the device and the signal-receiving apparatus, using a switch in order to avoid a signal interference by the signal-receiving apparatus.

15. The device according to claim 2 wherein for all signal paths, the device exhibits contact elements in which a signal may be fed externally into a signal path using a contact element.

16. The device according to claim 14 wherein a signal path disconnection is allocated locally to a multicolor display element.

17. The device according to claim 2 wherein the evaluation unit of the device obtains its power supply through at least one of the apparatuses.

18. The device according to claim 2 wherein a contact element is allocated locally to a multicolor display element.

19. The device according to claim 14 wherein a signal path disconnection and a contact element is allocated locally to a multicolor display element.
