Abstract

A system includes a user interface device that is capable of communicating wirelessly with a tool. In one example arrangement, the tool can be a well tool or a tool having one or more explosive components. The user interface device is adapted to send commands to the tool to perform tasks, such as test operations. In one arrangement, the user interface device is a personal digital assistant (PDA) having a graphical user interface (GUI).

Claims

1. A system, comprising:

a portable user interface device;

a control module; and

a tool selected from the group consisting of a well tool and a tool containing one or more explosive elements, the tool coupled to the control module,

the portable user interface device adapted to communicate wirelessly with the control module,

wherein the control module is adapted to send a command to the tool to perform a test of the tool,

wherein the control module is responsive to wireless signals from the portable user interface device to send coded signals to the tool for testing the tool, the control module comprising a detector adapted to detect a status of one or more components of the tool,

wherein the detector comprises a current detector adapted to detect a level of electrical current.

2. The system of claim 1, wherein the portable user interface device comprises a display to display a graphical user interface.

3. The system of claim 2, wherein the graphical user interface comprises one or more graphical elements selectable to control the tool.

4. The system of claim 3, wherein the portable user interface device comprises an infrared transceiver adapted to communicate infrared signals.

5. The system of claim 1, wherein the portable user interface device comprises a personal digital assistant.

6. The system of claim 1, wherein the user interface device comprises a display to show a result of the test.

7. The system of claim 1, wherein the tool comprises plural control units, the user interface device adapted to send commands to the tool to successively test the plural control units.

8. The system of claim 7, wherein the tool comprises a string of elements, and the control module is coupled to the string of elements.

9. The system of claim 1, wherein the portable user interface device comprises a graphical user interface having one or more control elements selectable to activate testing of the tool.

10. The system of claim 9, wherein the tool comprises plural control units, the portable user interface device adapted to send commands to sequentially test the plural control units.

11. The system of claim 10, wherein the graphical user interface is adapted to display acquired information pertaining to each of the control units.

12. The system of claim 9, wherein the graphical user interface is adapted to display information pertaining to control units for explosive devices.

13. The system of claim 1, wherein the portable user interface device is adapted to check that communications with components of the tool is functional.

14. The system of claim 13, wherein the portable user interface device is adapted to verify addresses of the components in the tool.

15. A system, comprising:

a portable user interface device;

a control module; and

a tool selected from the group consisting of a well tool and a tool containing one or more explosive elements, the tool coupled to the control module,

the portable user interface device adapted to communicate wirelessly with the control module,

wherein the control module further comprises a current detector to detect current from the tool, the control module adapted to use an output of the current detector to determine for presence of components in the tool.

16. The system of claim 15, wherein the control module is adapted to further use the output of the current detector to determine if a component of the tool has failed.

17. The system of claim 15, wherein the control module is adapted to communicate an operational status of each of the components to the portable user interface device.

18. The system of claim 17, wherein the portable user interface device has a graphical user interface to display the operational status of each of the components in the tool.

19. A system, comprising:

a portable user interface device;

a control module; and

a tool selected from the group consisting of a well tool and a tool containing one or more explosive elements, the tool coupled to the control module,

the portable user interface device adapted to communicate wirelessly with the control module,

wherein the control module further comprises a current detector to detect current from the tool, the control module adapted to use an output of the current detector to determine if a component in the tool has failed.

20. The system of claim 19, wherein the control module is adapted to communicate an operational status of each of the components to the portable user interface device.

21. The system of claim 20, wherein the portable user interface device has a graphical user interface to display the operational status of each of the components in the tool.

22. A system, comprising:

a portable user interface device;

a control module; and

a tool selected from the group consisting of a well tool and a tool containing one or more explosive elements, the tool coupled to the control module,

the portable user interface device adapted to communicate wirelessly with the control module,

wherein the control module is adapted to send a command to the tool to perform a test of the tool,

wherein the control module is responsive to wireless signals from the portable user interface device to send coded signals to the tool for testing the tool, the control module comprising a detector adapted to detect a status of one or more components of the tool,

wherein the detector is adapted to detect for at least one of the following failures;

mis-wiring of a components in the tool;

a short in the tool; and

the presence of a detonator in the tool.
