Abstract

A system, method and apparatus for configuring a node in a sensor network. A sensor service can enable sensor applications to customize the collection and processing of sensor data from a monitoring location. In one embodiment, sensor applications can customize the operation of nodes in the sensor network via a sensor data control system.

First claim

What is claimed is:

1. A method, comprising:
transmitting, by a sensor data control system using a hypertext transfer protocol, a configuration message usable by a wireless node that supports one or more sensors, the configuration message including configuration information that enables the wireless node to change at least one configuration setting of the wireless node;
comparing, by the sensor data control system, a first configuration hash value generated using first configuration settings of the wireless node to a second configuration hash value generated using second configuration settings of the wireless node determined using the configuration information; and
when the comparison indicates that the first configuration hash value is different from the second configuration hash value, retransmitting, by the sensor data control system, the configuration message using the hypertext transfer protocol.

2. The method of claim 1 , wherein the at least one configuration setting enables activation of one or more sensors supported by the wireless node from a deactivated state.

3. The method of claim 1 , wherein the at least one configuration setting enables a change of a measurement resolution of one or more sensors supported by the wireless node.

4. The method of claim 1 , wherein the at least one configuration setting enables a change of a polling frequency of the wireless node.

5. The method of claim 1 , wherein the at least one configuration setting enables a change of a sampling frequency by one or more sensors supported by the wireless node.

6. The method of claim 1 , wherein the at least one configuration setting enables a change of a device address or register address for a Modbus interface command generated by the wireless node.

7. The method of claim 1 , wherein the at least one configuration setting enables a change of a state in an actuator device.

8. A method, comprising:
receiving, by a sensor data control system, a status message associated with a wireless node, the status message including a first configuration hash value generated using current configuration settings of the wireless node; and
initiating a transmission via a hypertext transfer protocol of an updated configuration setting usable by the wireless node when a comparison indicates that the first configuration hash value is different from a second configuration hash value generated using a stored set of configuration settings for the wireless node that includes the updated configuration setting.

9. The method of claim 8 , wherein the updated configuration setting enables an activation of one or more sensors from a deactivated state.

10. The method of claim 8 , wherein the updated configuration setting enables a change in measurement resolution of one or more sensors.

11. The method of claim 8 , wherein the updated configuration setting enables a change in polling frequency by the wireless node.

12. The method of claim 8 , wherein the updated configuration setting enables a change in sampling frequency by one or more sensors.

13. The method of claim 8 , wherein the updated configuration setting enables a change in a device address or register address for a Modbus interface command.

14. The method of claim 8 , wherein the updated configuration setting enables a change in state of an actuator device.

15. A non-transitory computer-readable medium having a configuration update tool stored thereon for use by one or more server devices, the configuration tool including:
a transmission section that when executed, causes the configuration update tool to transmit a configuration message usable by a wireless node that supports one or more sensors, the configuration message including configuration information that enables the wireless node to change at least one configuration setting of the wireless node;
a comparison section that when executed, causes the configuration update tool to compare a first configuration hash value generated using first configuration settings of the wireless node to a second configuration hash value generated using second configuration settings of the wireless node determined using the configuration information; and
an update section that when executed, causes the configuration update tool to initiate a configuration update retransmission when the comparison indicates that the first configuration hash value is different from the second configuration hash value, wherein the configuration update retransmission includes the configuration information.

16. The non-transitory computer-readable medium of claim 15 , wherein the configuration information enables the wireless node to change a configuration setting that enables activation of one or more sensors supported by the wireless node from a deactivated state.

17. The non-transitory computer-readable medium of claim 15 , wherein the configuration information enables the wireless node to change a configuration setting that enables a change of a measurement resolution of one or more sensors supported by the wireless node.

18. The non-transitory computer-readable medium of claim 15 , wherein the configuration information enables the wireless node to change a configuration setting that enables a change of a polling frequency of the wireless node.

19. The non-transitory computer-readable medium of claim 15 , wherein the configuration information enables the wireless node to change a configuration setting that enables a change of a device address or register address for a Modbus interface command generated by the wireless node.

20. The non-transitory computer-readable medium of claim 15 , wherein the configuration information enables the wireless node to change a configuration setting that enables a change of a state in an actuator device.
