Abstract

Claims (57)

1. A method, comprising:

executing, by a utility meter comprising one or more computer processors, a first software agent configured to collect utility usage data on behalf of a first utility provider;

executing, by the utility meter concurrently with the first software agent, a second software agent configured to collect utility usage data on behalf of a second utility provider; and

managing, by the utility meter, allocation of resources to the first software agent and the second software agent, wherein managing the allocation of resources comprises receiving, from the first software agent by a resource allocation module associated with the utility meter, a request to access a resource.

2. The method of claim 1 , wherein managing the allocation of resources further comprises:

allocating, by the resource allocation module, the requested resource to the first software agent, wherein the second software agent is not permitted to modify the resource while the resource is allocated to the first software agent.

3. The method of claim 2 , wherein allocating the requested resource comprises allocating a metrology resource associated with the collection of utility usage data by the utility meter.

4. The method of claim 2 , further comprising:

determining, by a security module associated with the utility meter, that the first software agent has permission to access the resource,

wherein allocating the requested resource comprises allocating the requested resource subsequent to determining that the first software agent has permission to access the resource.

5. The method of claim 2 , further comprising:

determining, by a watchdog module associated with the utility meter, whether the first software agent releases the resource within a predetermined period of time; and

terminating, by the watchdog module, the first software agent if it is determined that the first software agent does not release the resource within the predetermined period of time.

6. The method of claim 1 , further comprising:

validating, by a security module associated with the utility meter, a first bytecode signature associated with the first software agent and a second bytecode signature associated with the second software agent,

wherein executing the first software agent and the second software agent comprises executing the first software agent and the second software agent based at least in part upon the validation.

7. The method of claim 1 , further comprising:

receiving, from the first software agent by an event module associated with the utility meter, a registration request for an announcement associated with a designated event; and

communicating, by the event module to the first software agent upon the occurrence of the designated event, the requested announcement.

8. The method of claim 1 , further comprising:

determining, by a watchdog module associated with the utility meter, whether an annunciation message is received from the first software agent within a predetermined period of time; and

terminating, by the watchdog module, the first software agent if it is determined that the annunciation message has not been received.

9. The method of claim 8 , further comprising:

determining, by the watchdog module, whether the first software agent is waiting for a resource allocated to the second software agent,

wherein terminating the first software agent comprises terminating the first software agent based upon a determination that the first software agent is not waiting for a resource allocated to the second software agent.

10. A utility meter, comprising:

at least one memory configured to store computer-executable instructions associated with a first software agent and a second software agent; and

at least one processor configured to access the at least one memory and execute the computer-executable instructions to:

execute the first software agent to collect utility usage data on behalf of a first utility provider; and

execute the second software agent to collect utility usage data on behalf of a second utility provider,

wherein the at least one memory further comprises additional computer-executable instructions associated with software management,

and wherein the at least one processor is further configured to manage the allocation of resources to the first software agent and the second software agent by executing the additional computer-executable instructions to:

receive, from the first software agent, a request to access a resource.

11. The utility meter of claim 10 , wherein the at least one processor is configured to manage the allocation of resources by further executing the additional computer-executable instructions to:

allocate the requested resource to the first software agent, wherein the second software agent is not permitted to modify the resource while the resource is allocated to the first software agent.

12. The utility meter of claim 11 , wherein the resource comprises a metrology resource associated with the collection of utility usage data by the utility meter.

13. The utility meter of claim 11 , wherein the at least one processor is further configured to execute the additional computer-executable instructions to:

determine that the first software agent has permission to access the resource; and

wherein the requested resource is allocated subsequent to determining that the first software agent has permission to access the resource.

14. The utility meter of claim 11 , wherein the at least one processor is further configured to execute the additional computer-executable instructions to:

determine whether the first software agent releases the resource within a predetermined period of time; and

terminate the first software agent if it is determined that the first software agent does not release the resource within the predetermined period of time.

15. The utility meter of claim 10 , wherein the at least one memory further comprises additional computer-executable instructions associated with software agent management, and

wherein the at least one processor is further configured to execute the additional computer-executable instructions to:

validate a first bytecode signature associated with the first software agent and a second bytecode signature associated with the second software agent; and

execute the first software agent and the second software agent based at least in part upon the validation.

16. The utility meter of claim 10 , wherein the at least one memory further comprises additional computer-executable instructions associated with software agent management, and

wherein the at least one processor is further configured to execute the additional computer-executable instructions to:

receive, from the first software agent, a registration request for an announcement associated with a designated event; and

communicate, to the first software agent upon the occurrence of the designated event, the requested announcement.

17. The utility meter of claim 10 , wherein the at least one memory further comprises additional computer-executable instructions associated with software agent management, and

wherein the at least one processor is further configured to execute the additional computer-executable instructions to:

determine whether an annunciation message is received from the first software agent within a predetermined period of time; and

terminate the first software agent if it is determined that the annunciation message has not been received.

18. The utility meter of claim 17 , wherein the at least one processor is further configured to execute the additional computer-executable instructions to:

determine whether the first software agent is waiting for a resource allocated to the second software agent; and

terminate the first software agent based upon a determination that the first software agent is not waiting for a resource allocated to the second software agent.
