Abstract

A modification of a sensor data management system to enable discrete sensor applications. A sensor data control system enables discrete sensor applications to control the configuration, collection, processing, and distribution of sensor data produced by selected sensors at various monitored locations. The sensor service offered by the sensor data control system can be leveraged by any sensor application having an interest in any part of one or more monitored locations.

Claims

1. A method, comprising:

transmitting, to a sensor data control system, a first hypertext transfer protocol message via the Internet, the first hypertext transfer protocol message requesting a change in Modbus configuration information for a wireless node in a wireless sensor network at a monitored location, the Modbus configuration information used to configure the wireless node to transmit periodic Modbus interface command requests to a Modbus device connected to the wireless node via a wired interface, each of the periodic Modbus interface command requests designed to retrieve sensor data based on measurements by one or more of a plurality of sensors supported by the Modbus device, the first hypertext transfer protocol message including a wireless node identifier, and one or more configuration data values reflective of the change;

transmitting, to the sensor data control system, a second hypertext transfer protocol message via the Internet, the second hypertext transfer protocol message requesting a series of sensor data based on measurements by a first of the plurality of sensors, the series of sensor data retrieved from the Modbus device in response to a transmission of a series of Modbus interface command requests by the wireless node to the Modbus device, the second hypertext transfer protocol message including the wireless node identifier; and

receiving, from the sensor data control system in response to the second hypertext transfer protocol message, the series of sensor data based on the measurements by the first of the plurality of sensors.

2. The method of claim 1, further comprising transmitting, to the sensor data control system, a third hypertext transfer protocol message via the Internet, the third hypertext transfer protocol message requesting an activation of a sensor in the wireless node from a deactivated state.

3. The method of claim 1, further comprising transmitting, to the sensor data control system, a third hypertext transfer protocol message via the Internet, the third hypertext transfer protocol message requesting a change in configuration in a measurement resolution of a sensor.

4. The method of claim 1, further comprising transmitting, to the sensor data control system, a third hypertext transfer protocol message via the Internet, the third hypertext transfer protocol message requesting a reset of the wireless node.

5. The method of claim 1, wherein the one or more configuration data values includes an identification of a device address for the Modbus interface command requests.

6. The method of claim 1, wherein the one or more configuration data values includes an identification of a register address for the Modbus interface command requests.

7. The method of claim 1, further comprising:

analyzing the received series of sensor data to estimate a demand for a resource at the monitored location; and

transmitting, to the sensor data control system, a third hypertext transfer protocol message via the Internet, the third hypertext transfer protocol message requesting a change in configuration of an actuator unit at the monitored location to effect a response action identified based on the analysis.

8. A method, comprising:

receiving, from a client device, a first hypertext transfer protocol message via the Internet, the first hypertext transfer protocol message requesting a change in Modbus configuration information for a wireless node in a wireless sensor network at a monitored location, the Modbus configuration information used to configure the wireless node to transmit periodic Modbus interface command requests to a Modbus device connected to the wireless node via a wired interface, each of the periodic Modbus interface command requests designed to retrieve sensor data based on measurements by one or more of a plurality of sensors supported by the Modbus device, the first hypertext transfer protocol change message including a wireless node identifier, and configuration information reflective of the change;

transmitting, to a gateway device at the monitored location, a second hypertext transfer protocol message via the Internet that includes an instruction to effect the change in the configuration of the wireless node to transmit the periodic Modbus interface command requests to the Modbus device, the second hypertext transfer protocol message including one or more configuration data values based on the configuration information;

receiving, from the gateway device, a third hypertext transfer protocol message that includes first information about an updated configuration of the wireless node;

updating, based on the received first information, a stored current status of the updated configuration of the wireless node; and

transmitting, to the client device, a fourth hypertext transfer protocol message that includes second information about the updated configuration of the wireless node, the second information enabling the client device to confirm that the current status of the updated configuration of the wireless node reflects the in Modbus configuration information requested in the first hypertext transfer protocol message.

9. The method of claim 8, further comprising transmitting, to the gateway device, a fifth hypertext transfer protocol message that is configured to activate a sensor in the wireless node from a deactivated state.

10. The method of claim 8, further comprising transmitting, to the gateway device, a fifth hypertext transfer protocol message that is configured to change a measurement resolution of a sensor.

11. The method of claim 8, further comprising transmitting, to the gateway device, a fifth hypertext transfer protocol message that is configured to reset the wireless node.

12. The method of claim 8, wherein the one or more configuration data values includes a device address for the Modbus interface command requests.

13. The method of claim 8, wherein the one or more configuration data values includes a register address for the Modbus interface command requests.
