Abstract

A system and method of tracking location and orientation of power tools utilized in the assembly and maintenance of complex systems is disclosed. The system can facilitate collaboration between maintenance and alert maintenance personnel to complete complex system activities.

Claims

1. A method of providing reliable assembly and maintenance of complex systems comprising:

sensing operational characteristics associated with operation of a power tool, the operational characteristics comprising location and performance information associated with use of the tool;

calibrating the power tool with an initial power tool location by placing the power tool at a predetermined location with respect to a complex system and identifying a procedure to be performed by the power tool on the complex system;

transmitting the operational characteristics and the procedure to be performed by the power tool to a computer;

receiving an operation instruction from the computer in response to the tool transmitting the operational characteristics and the procedure to be performed; and

displaying the operation instruction on a display unit of the tool.

2. The method of claim 1, comprising controlling the power tool based on the operational characteristics.

3. The method of claim 1, wherein sensing the operational characteristics comprises utilizing an accelerometer.

4. The method of claim 3, comprising transmitting the operational characteristics wirelessly.

5. The method of claim 1, further comprising tracking a location coordinate associated with the power tool.

6. The method of claim 1, further comprising:

comparing at least one of the operational characteristics to a threshold value associated with a task; and

controlling the power tool based on the comparison.

7. The method of claim 1, further comprising:

generating, with the computer, the operation instruction in response to receipt of the operational characteristics from the tool.

8. The method of claim 1, further comprising

configuring at least one of the operational characteristics of the tool in response to receipt of the operation instruction.

9. The method of claim 1, further comprising:

determining completion of the operation instruction by the tool;

receiving, from the computer, a next operation instruction and a next location at which the tool is to be used; and

displaying the next operation instruction and next location on the display of the tool.

10. A power tool for use with a complex system comprising:

at least one sensor to sense operational characteristics associated with the tool being applied to a task, the operational characteristics comprising tool location and tool performance;

a transmit-receive device communicatively coupling the tool with a computer, the tool receiving an operation instruction from the computer in response to the tool transmitting the operational characteristics and a procedure to be performed to the computer;

a controller operatively coupled with the sensor and the transmit-receive device, the controller being configured and operative to selectively transmit a tool location calibration signal responsive to the power tool being placed at a predetermined location with respect to a complex system; and

a display arranged to display the operational instruction for the tool upon receipt of the operation instruction.

11. The power tool of claim 10, further comprising a communication port to receive the operational instruction from the computer and to send the operational characteristics to the computer on completion of the task, the communication port being at least one of a serial port, USB port, and a wireless transmitter/receiver port.

12. The power tool of claim 10, wherein the operation instruction is executed by the power tool.

13. The power tool of claim 10, wherein the power tool is a hand held rotary driver.

14. The power tool of claim 10, wherein the controller sets the tool performance in response to receipt of the operation instruction.

15. The power tool of claim 10, wherein the transmit-receive device transmits completion of the operation instruction to the computer and receives a next operation instruction from the computer in return.

16. The power tool of claim 10, wherein the transmit-receive device performs at least one of transmitting and receiving wirelessly.
