Abstract

A cloud-based instrument driver system enables a user device to interact with one or more instruments through a remotely located driver cloud. The driver cloud may store drivers and ancillary software. The user device may be connected to each instrument either directly or indirectly, for example, over one or more computer networks, and may be connected to and communicate directly with the driver cloud over the computer network. However, the driver cloud and the instrument may not be in direct communication. The user device relays commands and responses to and from the instrument to the driver cloud for translation into a format suitable for processing by the user device. Utilization of the driver cloud obviates the need to obtain, install and maintain any drivers and/or ancillary software on the user device in order to enable the device to interact with the instrument.

Claims

1. A non-transitory computer-readable medium comprising instructions, the program instructions when executed by a processing element operable to:

receive, at a user device running an application program, a first command directed to an instrument, where the instrument is a test and measurement device adapted to respond to commands that conform to an instrument protocol, the first command;

evaluated by the application program, and not conforming to the instrument protocol;

send the first command to a driver cloud, the driver cloud located remotely relative to the user device;

receive, from the driver cloud, a second command at the user device, the second command being a translated version of the first command that conforms to the instrument protocol; and

issue, from the user device, the second command to the instrument.

2. The non-transitory computer-readable medium of claim 1 wherein the instrument is connected to or simulated by the processing element.

3. The non-transitory computer-readable medium of claim 1 wherein the instrument protocol is implemented through at least one of an instrument specific driver, an interchangeable virtual instrument (IVI), and a Virtual Instrument Software Architecture (VISA) module.

4. The non-transitory computer-readable medium of claim 1 further comprising instructions executable by the processing element to:

receive, from the driver cloud, a message, the received message including the second command; and

recover the second command from the message.

5. The non-transitory computer-readable medium of claim 1 further comprising instructions executable by the processing element to:

receive, from the instrument, a first response, the first response conforming to the instrument protocol;

send the first response received from the instrument to the driver cloud;

receive from the driver cloud a second response, the second response being a translated version of the first response that conforms to a format of the application program; and

provide the second response to the application program.

6. The non-transitory computer-readable medium of claim 1 further comprising instructions executable by the processing element to:

open a connection with the driver cloud, wherein the connection is opened before the first command is sent.

7. The non-transitory computer readable medium of claim 1 wherein the application program is selected from the group consisting of:

a graphical modeling program, an array-based analysis program, and a browser.

8. The non-transitory computer readable medium of claim 7 wherein the graphical program is a dataflow program or a time-based simulation program.

9. The non-transitory computer readable medium of claim 1 wherein the test and measurement device is a computer-controlled, data acquisition device.

10. The non-transitory computer readable medium of claim 9 wherein the computer-controlled, data acquisition device is selected from the group consisting of:

a digital multimeter, a function generator, and an oscilloscope.

11. The non-transitory computer readable medium of claim 1 wherein the user device is free from including a driver for the instrument.

12. A non-transitory computer-readable medium comprising instructions, the program instructions when executed by a processing element operable to:

receive, from an application program operating on behalf of a user device, a first command directed to an instrument, where the instrument is a test and measurement device adapted to respond to commands that conform to an instrument protocol, the first command;

received at a driver cloud that is remotely located from the user device,

evaluated by the application program, and

not conforming to the instrument protocol;

select, from a plurality of available drivers of the driver cloud, a driver for the instrument based on information included in the first command identifying the instrument, the selected driver implementing the instrument protocol;

using the selected driver, translate the first command into a second command that conforms to the instrument protocol; and

send the second command from the driver cloud to the user device.

13. The non-transitory computer-readable medium of claim 12 wherein the application program is executing either on the user device, or remotely to the user device.

14. The non-transitory computer-readable medium of claim 12 further comprising instructions executable by the processing element to:

receive a first response, the first response

generated by the instrument, and

conforming to the instrument protocol;

utilizing the selected driver, translate the first response into a second response that conforms to a format of the application program; and

send the second response to the application program.

15. The non-transitory computer-readable medium of claim 14 wherein the first response is received from

the application program operating on behalf of the user device, or

the instrument.

16. The non-transitory computer-readable medium of claim 15 wherein the driver cloud and the instrument are in one sub-network.

17. The non-transitory computer-readable medium of claim 12 further comprising instructions executable by the processing element to:

determine one or more characteristics of the instrument, wherein the driver is selected based on the one or more characteristics of the instrument.

18. The non-transitory computer readable medium of claim 17 wherein the one or more characteristics of the instrument include

a type of instrument,

a manufacturer of the instrument,

a model of the instrument,

a revision of software installed on board the instrument,

one or more optional features of the instrument,

one or more user specified characteristics, and

a type of physical connection between the user device and the instrument.

19. The non-transitory computer readable medium of claim 12 wherein

the driver cloud includes a driver store having a plurality of drivers, and

the driver is selected from the driver store.

20. The non-transitory computer readable medium of claim 19 further comprising instructions executable by the processing element to:

update one or more drivers in the driver store.

21. The non-transitory computer readable medium of claim 14 further comprising instructions executable by the processing element to:

select one or more ancillary programs, wherein
