Abstract

A system, method, and computer-readable medium for the discovery and registration of controlled devices associated with self-describing Modules in a control system are provided. A controlled device associated with a self-describing module is coupled with a master controller on which the self-describing module is installed. A remote monitoring system is communicatively coupled with the master controller, and a remote monitoring system agent is installed on the master controller. The agent discovers a Module associated with the controlled device and queries the Module for a version thereof. The agent then evaluates whether the Module is self-describing. In the event the Module is self-describing, the agent requests a run-time capabilities object from the Module and registers the controlled device with the remote monitoring system according to the capabilities object.

Claims

1. A method of discovery and registration of a controlled device for control thereof, comprising:

discovering a module associated with the controlled device by an agent associated with a remote monitoring system;

evaluating whether the module is self-describing;

responsive to determining the module is self-describing, requesting a run-time capabilities object from the module;

receiving the capabilities object; and

registering the controlled device with the remote monitoring system according to the capabilities object.

2. The method of claim 1, wherein discovering the module comprises discovering the module by invoking an OSGi method by the agent.

3. The method of claim 1, further comprising querying the module for a version of the module.

4. The method of claim 3, wherein evaluating whether the module is self-describing comprises evaluating the version of the module.

5. The method of claim 1, further comprising:

receiving a command for an operation to be performed on the controlled device;

determining the module is self-describing;

accessing the capabilities object; and

invoking the command responsive to determining the command conforms to the capabilities object.

6. The method of claim 1, further comprising:

discovering a second module associated with a second controlled device by the agent;

evaluating whether the second module is self-describing;

responsive to determining the second module is not self-describing, determining a device type and capabilities corresponding thereto; and

generating a second capabilities object based on the capabilities corresponding to the device type.

7. The method of claim 6, further comprising registering the second controlled device with the remote monitoring system according to the second capabilities object.

8. The method of claim 7, further comprising:

receiving a command for an operation to be performed on the second controlled device;

determining the second module is not self-describing;

accessing the second capabilities object;

performing reflection on the second capabilities object; and

invoking the command responsive to determining the command conforms to the second capabilities object.

9. A computer-readable medium having computer-executable instructions for execution by a processing system, the computer-executable instructions for discovery and registration of a controlled device for control thereof, the computer-readable medium comprising instructions that, when executed, cause the processing system to:

discover a module associated with the controlled device by an agent associated with a remote monitoring system;

query the module for a version of the module;

evaluate whether the module is self-describing;

responsive to determining the module is self-describing, request a run-time capabilities object from the module;

receive the capabilities object; and

register the controlled device with the remote monitoring system according to the capabilities object.

10. The computer-readable medium of claim 9, wherein the instructions that discover the module comprise instructions that, when executed, cause the processing system to invoke an OSGi method by the agent.

11. The computer-readable medium of claim 9, wherein the instructions that evaluate whether the module is self-describing comprise instructions that, when executed, cause the processing system to evaluate the version of the module.

12. The computer-readable medium of claim 9, further comprising instructions that, when executed, cause the processing system to:

receive a command for an operation to be performed on the controlled device;

determine the module is self-describing;

access the capabilities object; and

invoke the command responsive to determining the command conforms to the capabilities object.

13. The computer-readable medium of claim 9, further comprising instructions that, when executed, cause the processing system to:

discover a second module associated with a second controlled device by the agent;

evaluate whether the second module is self-describing;

responsive to determining the second module is not self-describing, determine a device type and capabilities corresponding thereto; and

generate a second capabilities object based on the capabilities corresponding to the device type.

14. The computer-readable medium of claim 13, further comprising instructions that, when executed, cause the processing system to register the second controlled device with the remote monitoring system according to the second capabilities object.

15. The computer-readable medium of claim 14, further comprising instructions that, when executed, cause the processing system to:

receive a command for an operation to be performed on the second controlled device;

determine the second module is not self-describing;

access the second capabilities object;

perform reflection on the second capabilities object; and

invoke the command responsive to determining the command conforms to the second capabilities object.

16. A control system for control of controlled devices deployed therein, comprising:

a controlled device having a self-describing module associated therewith;

a remote monitoring system; and

a master controller on which the self-describing module and an agent associated with the remote monitoring system are installed, wherein the remote monitoring system and the master controller are OSGi-compliant, wherein the agent discovers the module by invoking an OSGi method, queries the module for a version of the module, determines the module is self-describing, requests a run-time capabilities object from the module responsive to determining the module is self-describing, receives the capabilities object, and registers the controlled device with the remote monitoring system according to the capabilities object.

17. The system of claim 16, wherein the agent determines the module is self-describing by evaluating the version of the module.

18. The method of claim 16, wherein the agent receives, from the remote monitoring system, a command for an operation to be performed on the controlled device, accesses the capabilities object, and invokes the command responsive to determining the command conforms to the capabilities object.

19. The system of claim 16, wherein the agent discovers a second module associated with a second controlled device, evaluates whether the second module is self-describing, determines a device type and capabilities corresponding thereto responsive to determining the second module is not self-describing, and generates a second capabilities object based on the capabilities corresponding to the device type.

20. The system of claim 19, wherein the agent registers the second controlled device with the remote monitoring system according to the second capabilities object.
