Abstract

A system and method for communicating with power tools using a universal protocol. The universal protocol may be implemented using a universal core module that is installed across a variety of power tools and other devices to enable communications therewith. Communications to and from the power tools are translated to a universal protocol once received. The translated communications are handled by the universal core module of a particular tool according to a set of rules. In response, the universal core module outputs communications according to the universal protocol and the set of rules, which may be translated to another protocol for receipt by components of the tool or an external device. The communications may be used, for example, to obtain tool performance data from the tools and to provide firmware updates.

Claims

1. A method of implementing a universal protocol on a plurality of tools, the plurality of tools including a variety of power tool types, the method comprising:

generating an interfacing module including

universal core module for implementing the universal protocol, the universal core module being generic to the plurality of tools and including a set of rules enabling interpretation and handling of communications that are in accordance with the universal protocol, and

an interface module particular to each of the power tool types, the interface module configured

to translate communications on route to the universal core module to the universal protocol and

to translate communications output by the universal core module from the universal protocol to another protocol; and

installing the interfacing module on a memory of each of the plurality of tools.

2. The method of claim 1, wherein the interface module includes:

physical interface software enabling translation of communications between the universal core module and external devices; and

tool component interface software enabling translation of communications between the universal core module and internal components of the plurality of tools.

3. The method of claim 2, wherein generating the physical interface software comprises determining physical interface components and associated protocols for each of the tool types.

4. The method of claim 1, further comprising:

providing, at a physical interface of a tool of the plurality of tools, commands according to the another protocol;

translating, by the interface module of the tool, the commands from the another protocol to the universal protocol to form translated commands;

providing the translated commands to the universal core module; and

executing, by the universal core module, the translated commands.

5. The method of claim 1, further comprising:

generating application software and parameters particular to each tool;

using the interfacing module of each tool to install on each tool the application software and parameters particular to that tool.

6. The method of claim 5, further comprising:

generating an update for at least one of the application software and parameters for at least one tool of the plurality of tools; and

installing the update on the at least one tool of the plurality of tools using the interfacing module.

7. The method of claim 1, further comprising capturing and storing performance data in the memory of each tool of the plurality of tools;

and

reading the performance data from the memory of each tool using an external device communicating with the interfacing module via a physical interface of each tool.

8. The method of claim 1, further comprising:

receiving a write command by the universal core module of a tool of the plurality of tools, the write command specifying a write to the memory of the tool; and

entering a safe mode after receipt of the write command and before commencing the write to the memory, wherein, in the safe mode, a motor of the tool is disabled until the write to the memory of the tool is completed.

9. The method of claim 1, wherein the variety of power tool types includes at least two of:

a drill, a circular saw, a jig saw, a band saw, a reciprocating saw, a screw driver, a grinder, an impact wrench, a rotary hammer, and an impact driver.

10. A universal protocol system comprising:

a plurality of tools including a variety of power tool types, each tool including a memory;

interfacing module installed on the memory of each tool, the interfacing module including

a universal core module for implementing a universal protocol, the universal core module being generic to the plurality of tools and including a set of rules enabling interpretation and handling of communications that are in accordance with the universal protocol, and

an interface module particular to each of the power tool types, the interface module configured to translate communications on route to the universal core module to the universal protocol and to translate communications output by the universal core module from the universal protocol to another protocol.

11. The universal protocol system of claim 10, wherein the interface module includes:

physical interface software enabling translation of communications between the universal core module and external devices; and

tool component interface software enabling translation of communications between the universal core module and internal components of the plurality of tools.

12. The universal protocol system of claim 11, wherein the physical interface software is generated based on determining physical interface components and associated protocols for each of the tools types.

13. The universal protocol system of claim 10, wherein each tool of the plurality of tools includes a physical interface that is communicatively coupled to an external device and that is communicatively coupled to the universal core module via a physical interface module, the physical interface module translating commands from the external device to the universal protocol to form translated commands.

14. The universal protocol system of claim 13, wherein the universal core module of at least one tool of the plurality of tools receives and executes the translated commands from the physical interface module of the at least one tool.

15. The universal protocol system of claim 14, wherein the translated commands include a write of a software application and parameters to the memory of the at least one tool.

16. The universal protocol system of claim 14, further comprising:

sensors in each tool that generate performance data; and

performance data stored in the memory of each tool,

wherein the translated commands include a read of the performance data stored in the memory of the at least one tool.

17. The universal protocol system of claim 10, further comprising application software and parameters particular to each tool, wherein the application software and parameters particular to each tool are installed on the memory of each tool, respectively, using the interfacing module of each tool, respectively.

18. The universal protocol system of claim 17, further comprising an update for at least one of the application software and parameters for at least one tool of the plurality of tools, wherein the update is installed on the memory of the at least one tool using the interfacing module of the at least one tool.

19. The universal protocol system of claim 10, further comprising a safe mode on each tool of the plurality of tools, the safe mode disabling operation of a motor of an associated tool until execution of a write to the memory of the associated tool is completed.

20. The universal protocol system of claim 10, wherein the variety of power tool types includes at least two of:

a drill, a circular saw, a jig saw, a band saw, a reciprocating saw, a screw driver, a grinder, an impact wrench, a rotary hammer, and an impact driver.
