Abstract

A diagnostic system for a transportation device includes an analyzer unit. The analyzer unit includes a user defined sequence logic map. The sequence logic map defines a sequence for a plurality of name inputs. The analyzer unit is configured to monitor the operating condition of the plurality of named inputs and compare the operating condition of the plurality of named inputs with the user defined sequence logic map. The analyzer unit communicates the comparison in a notification.

Claims

1. A diagnostic system for a transportation device comprising:

an analyzer unit connected to user selected circuit points within a transportation device controller, the analyzer unit including a user defined sequence logic map defining a sequence for a plurality of name inputs, the named inputs having operating conditions at given points in time pre-defined by the user, the analyzer being configured to monitor the condition of the plurality of named inputs during operation of the transportation device;

wherein the analyzer unit is configured to compare the operating condition of the plurality of named inputs with the user pre-defined sequence logic map and communicate the comparison in a notification.

2. The diagnostic system of claim 1 wherein the analyzer unit communicates the notification to a host computer.

3. The diagnostic system of claim 2 wherein the analyzer unit is connected to the host computer by a telephone line.

4. The diagnostic system of claim 2 wherein the host computer communicates with a peripheral device.

5. The diagnostic system of claim 1 wherein the transportation device is an elevator.

6. The diagnostic system of claim 1 wherein the analyzer unit is connected to the named inputs by electrical wiring.

7. The diagnostic system of claim 1 wherein the named inputs have a measurable voltage.

8. The diagnostic system of claim 1 wherein the named inputs generate an analog signal.

9. The diagnostic system of claim 1 wherein the sequence logic map describes acceptable, unacceptable and ignored behavior of the named inputs.

10. The diagnostic system of claim 1 wherein the notification includes data illustrated in an oscilloscope style display.

19. The diagnostic system of claim 1, wherein the notification includes information of correct sequences and correct durations of the named inputs in the sequence logic map.

11. A method for diagnosing control system malfunctions, the method comprising the steps of:

selecting and naming a plurality of control system points;

providing an analyzer unit and connecting the analyzer unit to a transportation device controller, the analyzer unit including a user defined sequence logic map defining a sequence for the plurality of named control system points, the analyzer unit being configured to monitor the operating condition of the plurality of named control system points and communicate the comparison in a notification;

providing a host computer connected to the analyzer unit and configured to display the notification communicated by the analyzer unit;

pre-defining the operating conditions of the named control system points;

operating the control system;

collecting actual sequence data from the plurality of named control system points;

comparing the collected actual sequence data with the user pre-defined operating conditions of the named control system points in the sequence logic map; and

communicating the results of the comparison in a notification to the host computer.

12. The method of claim 11 wherein the analyzer unit is connected to the host computer by a telephone line.

13. The method of claim 11 wherein the host computer communicates with a peripheral device.

14. The method of claim 11 wherein the transportation device is an elevator.

15. The method of claim 11 wherein the analyzer unit is connected to the named inputs by electrical wiring.

16. The method of claim 11 wherein the named inputs generate an analog signal.

17. The method of claim 11 wherein the sequence logic map describes acceptable, unacceptable and ignored behavior of the named inputs.

18. The method of claim 11 wherein the notification includes data illustrated in an oscilloscope style display.

20. A diagnostic system for a group having two or more transportation devices, each transportation device having a controller, the diagnostic system comprising:

an analyzer unit attached to each controller of the transportation devices, the analyzer units being electrically connected to user selected circuit points within the attached controller, the analyzer units including a user defined sequence logic map defining a sequence for a plurality of name inputs, the named inputs having operating conditions at given points in time pre-defined by the user, the analyzer units being configured to monitor the condition of the plurality of named inputs during operation of the transportation devices; and

a host computer electrically connected to the analyzer units;

wherein the analyzer units are configured to compare the operating condition of the plurality of named inputs with the user pre-defined sequence logic map and communicate the comparison in a notification to the host computer.
