Abstract

Claims (49)

1. A home area network (HAN) device having a protocol language which is a non-JavaScript Object Notation (JSON) protocol language, the HAN device being communicatively coupled to an energy service interface (ESI) device which is communicatively coupled to an application head-end server of a network, and the HAN device comprising:

at least one processor having a cache memory with sufficient capability to store a JSON object and computer-executable instructions; configured to execute the computer-executable instructions to:

receive from the ESI device an instruction in a format that is not JSON protocol language;

convert the received instruction from the non-JSON protocol language to a JavaScript Object Notation (JSON) object by parsing the received instruction into at least one common interface model (CIM) object, generating a C programming structure for the at least one CIM object, and encoding the C programming structure using a JSON syntax to create a JSON object;

store the JSON object in the cache memory of the at least one processor; and

access the cache memory to retrieve the first JSON object, parse the first JSON object on the fly to determine the instruction, convert the parsed first JSON object into the protocol language used by the HAN device, and execute the instruction after the instruction has been converted, whereby parsing of the JSON object on the fly reduces the memory demands on the ESI device.

2. The HAN device of claim 1 , wherein the at least one processor is further configured to execute computer-executable instructions to transmit to the ESI device HAN device data comprising a second JSON object, the second JSON object being indicative of a previously presented state of the HAN device after execution of the received instruction by the HAN device.

3. A method for use with a home area network (HAN) device having a processor and a protocol language which is a non-JavaScript Object Notation (JSON) protocol language, the HAN device being communicatively coupled to an energy service interface (ESI) device which is communicatively coupled to an application headend server of a network, the method comprising:

receiving from the headend server by at least one processor of an energy service portal (ESP) a control instruction for the HAN device, the control instruction being received in a non-JavaScript Object Notation (JSON) protocol language;

converting the control instruction from the non-JSON protocol language to a JavaScript Object Notation (JSON) object, the converting comprising:

parsing the control instruction into at least one common interface model (CIM) object; generating a C programming structure for the at least one CIM object;

and encoding the C

programming structure using a JSON syntax to create the JSON object; and

transmitting the JSON object to the HAN device for execution of the control instruction by the HAN device,

execution of the control instruction by the HAN device including:

storing the JSON object in a cache memory of the processor having sufficient capability to store a JSON object;

accessing the cache memory of the processor to fetch the JSON object; parsing the JSON object on the fly;

converting the parsed JSON instruction into the protocol language used by the HAN device; and

executing the converted control instruction by parsing the JSON object on the fly in the HAN device.

4. The method of claim 3 wherein the JSON object is a first JSON object, further comprising, in an energy service interface (ESI) device, receiving from the HAN device, updated HAN device data encoded as a second JSON object.

5. The method of claim 4 further comprising, in the ESI device, converting the updated HAN device data, encoded as the second JSON object, to a common interface model (CIM) object and transmitting the CIM object to the headend server.

6. The method of claim 3 , wherein the at least one CIM object complies with a smart energy profile (SEP) standard.

7. The method of claim 3 , wherein converting the control instruction further comprises generating a C programming schema for each attribute of the at least one CIM object.

8. The method of claim 7 , wherein the C programming schema for each attribute of the CIM object is encoded using JSON syntax prior to transmitting the JSON object to the HAN device.

9. One or more non-transitory computer-readable media storing computer-executable instructions that, when executed by at least one processor, configure the at least one processor to perform operations comprising:

receiving, from a headend server, by at least one processor of an energy service portal (ESP), a control instruction for a home area network (HAN) device using a protocol language which is a non-JavaScript Object Notation (JSON) protocol language;

parsing the control instruction into at least one common interface model (CIM) object and at least one attribute;

generating a C programming structure for the at least one CIM object; generating a C programming schema for the at least one attribute;

encoding the C programming structure and the C programming schema using a JavaScript Object Notation (JSON) syntax to create a JSON object; and

transmitting the JSON object to the HAN device for executing the control instruction in the HAN device, wherein executing the control instruction in the HAN device comprises:

storing the JSON object in a cache memory of the at least one processor having sufficient capability to store the JSON object; and

accessing the cache memory of the at least one processor to execute the control instruction by parsing the JSON object on the fly in the HAN device, converting the parsed JSON instruction into the protocol language used by the HAN device, and executing the instruction after it has been converted.

10. A system for operating a home area network (HAN) device communicatively coupled to a metering device which is an energy service interface (ESI) device communicatively coupled to an application headend server of a first network comprising:

the metering device receiving an instruction message for the HAN device, the received instruction message being in a format that is not JavaScript Object Notation (JSON) syntax, the metering device converting the received non-JSON instruction message into a JavaScript Object Notation (JSON) object representing the instruction message, the converting including parsing the instruction message into at least one common interface model (CIM) object, generating a C programming structure for the at least one CIM object, and encoding the C programming structure using a JSON syntax to create the JSON object, and transmitting the JSON object to the HAN device which has a protocol language which is a non-JSON protocol language; and the HAN device, which has at least one processor having a cache memory having sufficient capability to store a JSON object, the processor configured to execute the computer-executable instructions, operating to:

receive from the metering device the transmitted JSON object;

store the JSON object in the cache memory of the at least one processor;
