Abstract

A power machine diagnostic system. The diagnostic tool system includes a first interface removably coupled to a power machine, a computer to identify a type of the power machine coupled at the first interface, and a second interface to interface between the tool and the computer.

Claims

1. A power machine diagnostic system and power machine assembly, the assembly comprising:

a power machine including;

a machine connector,

a data storage configured to store machine information, and

a machine controller coupled to the machine connector and the data storage, and configured to transmit the machine information from the data storage, and to receive data through the connector;

a portable diagnostic tool configured to be coupled to the power machine, the tool including;

a first connector configured to be removably coupled to the machine connector,

a processor configured to receive at least a first portion of the machine information through the first connector, and to send at least a second portion of the machine information,

a second connector configured to relay the at least a second portion of the machine information, and to receive data to be processed by the processor, and

a removable computer-readable medium receptacle configured to record at least a third portion of the machine information;

an external computing device configured to be removably coupled to the second connector, to receive the at least a second portion of the machine information, to identify a type of machine coupled to the first interface based on the received machine information, and to instruct the processor to record at least a fourth portion of the machine information.

2. The system of claim 1, wherein the tool further comprises a plurality of buttons configured to remote control the machine.

3. The system of claim 1, wherein the power machine comprises one of a skid steer loader, excavator, compactor, screed, air compressor, and road development machine.

4. The system of claim 1, wherein the receptacle comprises an opening configured to receive a removable computer-readable medium.

5. The system of claim 1, wherein the external computing device further comprises a software module configured to analyze the recorded machine information.

6. The system of claim 1, wherein the external computing device further comprises a software module configured to display the recorded machine information.

7. The system of claim 1, wherein the processor is further configured to receive data from the machine in a first format, and to convert the data into a second format readable by the external computing device.

8. The system of claim 1, wherein the processor is further configured to receive data from the external computing device in a first format, and to convert the data into a second format readable by the machine.

9. A method of diagnosing various, distinct power machines with a portable diagnostic tool, the power machine having an machine interface configured to communicate with a controller of the machine, the method comprising:

removably coupling a first interface of the tool to the machine interface of the power machine;

communicating data from the controller to the first interface through the machine interface;

receiving the data at a processing module of the tool through the first interface;

identifying a type of machine coupled to the first interface based on the received data at the processing module;

receiving from the processing module at the second interface a plurality of control instructions based on the identified machine;

communicating at least a portion of the control instructions from the processing module to the controller of the power machine through the respective first interface and machine interface; and

recording data indicative of the machine in response to the control instructions.

10. The method of claim 9, further comprising:

providing a plurality of control buttons on the tool; and

remote controlling the machine with the buttons.

11. The method of claim 9, wherein the power machine comprises one of a skid steer loader, excavator, compactor, screed, air compressor, and road development machine.

12. The method of claim 9, wherein recording data further comprises recording the data with a removable computer-readable medium.

13. The method of claim 9, further comprising analyzing and displaying the recorded data.

14. The method of claim 9, wherein receiving from the processing module at the second interface a plurality of control instructions comprises receiving from the processing module at the second interface a plurality of control instructions in a first data format.

15. The method of claim 14, further comprising converting the control instructions in the first data format into a second data format at the tool.

16. The method of claim 9, wherein communicating data from the controller of the machine further comprises receiving the data from the controller in a first data format.

17. The method of claim 16, further comprising converting the data in the first data format into a second format at the tool to be readable by the machine.

18. A portable diagnostic tool configured to be removably connected to a power machine having a machine controller configured to store machine information, and further having a machine connector, and the tool further configured to be removably connected to a computer, the tool comprising:

a first interface connector configured to be removably connected to the machine connector;

a tool controller configured to communicate with the machine controller through the first interface connector, to retrieve the machine information, and to communicate the machine information to the computer;

a second interface connector configured to be removably connected to the computer, to relay data including the machine information to the computer, and to receive instructions including data relating to the machine information from the computer to the tool controller and the machine controller; and

a removable computer-readable medium receptacle configured to record operating parameters of the machine in response to the instructions from the computer.

19. The tool of claim 18, further comprising a plurality of buttons configured to remote control the machine.

20. The tool of claim 18, wherein the power machine comprises one of a skid steer loader, excavator, compactor, screed, air compressor, and a road development machine.

21. The tool of claim 18, further the removable computer-readable medium receptacle comprising an opening configured to receive a removable computer-readable medium.

22. The tool of claim 18, wherein the computer further comprises a software module configured to analyze and display the recorded operating parameters.

23. The tool of claim 18, wherein the tool controller is further configured to receive data from the machine in a first format, and to convert the data into a second format readable by the computer.

24. The tool of claim 18, wherein the tool controller is further configured to receive data from the computer in a first format, and to convert the data into a second format readable by the machine.
