Abstract

A method for connecting low power radios into a self-assembling and self-healing network with multiple portals to higher speed networks such as, but not limited to, electrical or optical Ethernet is provided for monitoring transmission lines, for example, or other monitoring application. An arrangement of sensors is provided (e.g., sensors can be associated with clamps or positioned along infrastructure being monitored and without dependence on any clamps or other devices) that are designed to communicate and operate in an geographically distributed array to provide increased and autonomous monitoring of large utility, highway, communication and similar networks. A unique collection of sensors (e.g., an anemometer with no moving parts) provides comprehensive diagnostics for improved operation of large geographic scale utility, highway, communication and similar infrastructure.

First claim

What is claimed is:

1. A data acquisition device for acquiring data from a location comprising:
at least one sensor for determining at least one of a parameter and image associated with the location;
a radio interface for communicating to at least one of a monitoring device and at least one neighboring data acquisition device via a radio communication link within a selected range; and
a processing device connected to the at least one sensor and the radio interface, the processing device being programmed to receive and process inputs from the at least one sensor, and to generate messages for transmission via the radio interface;
wherein a network comprises a plurality of the data acquisition device and the monitoring device, and the processing device is configured to participate in multi-hop communications via the radio communication link with the other data acquisition devices and the monitoring device;
wherein each of the data acquisition devices is assigned a unique address, and configured to perform a self-assembling process that automatically configures the data acquisition device to communicate within the network, the processing device being configured to perform the self-assembling process by receiving a configuration message transmitted from the monitoring device via the radio communication link and forwarding the configuration message after incrementing a hop count provided therein, and by replying to a copy of the configuration message having a minimum hop count among copies of the configuration message transmitted by one or more of the other data acquisition devices; and
wherein the unique address of each of the data acquisition devices is a Media Access Control (MAC) address and the radio interface in each of the data acquisition devices is an encrypted radio interface configured to employ the self-assembling process that assembles each of the data acquisition devices into a communication network that obviates manual configuration of the radio interface in each of the data acquisition devices.

2. A data acquisition device as recited in claim 1 , wherein the processing device is configured to receive messages from at least one of the other data acquisition devices and the monitoring device, and determine from information provided in each of the messages which operation to perform from among process the message, repeat the message, and ignore the message depending on whether an address provided in the message corresponds to the address of the data acquisition device and depending on a hop count provided in the message.

3. A data acquisition device as recited in claim 2 , wherein the hop count in the information provided in each of the messages corresponds to the number of times the message has been repeated by one of the data acquisition devices, the processing device being configured to increment the hop count in the messages before it is repeated.

4. A data acquisition device as recited in claim 3 , wherein the processing device is configured to determine whether to repeat the message based on the number of hops and the address included in the message.

5. A data acquisition device as recited in claim 1 , where the data acquisition device is configured as a Layer 2 router.

6. A data acquisition device as recited in claim 5 , wherein information in each of the copies of the configuration message comprises the unique address of the data acquisition device that sent the copy and a hop count, and the processing device determines from the information in received copies of the configuration message the unique addresses of the other data acquisition devices in its vicinity and stores their unique addresses in a memory device.

7. A data acquisition device as recited in claim 6 , wherein the processing device determines, from the information in each of the copies of the configuration message transmitted by the other data acquisition devices in its vicinity, the respective hop counts between the monitoring device and corresponding ones of the other data acquisition devices.

8. A data acquisition device as recited in claim 7 , wherein the processing device determines whether to repeat a received message based on the hop count and the address included in the message.

9. A data acquisition device as recited in claim 7 , the processing device is configured to store a designated number of the unique addresses of the other data acquisition devices in the memory device based on their respective hop counts to the monitoring device.

10. A data acquisition device as recited in claim 5 , wherein monitoring device is configured to aggregate data about respective ones of the data acquisition devices from messages received from other data acquisition devices via the radio communication link.

11. A data acquisition device as recited in claim 10 , wherein each of the data acquisition devices comprises a corresponding Hypertext Markup Language (HTML) page.

12. A data acquisition device as recited in claim 10 , wherein the monitoring device is assigned an Internet Protocol address and configured to provide a user with a Hypertext Markup Language (HTML) page corresponding to the data acquisition device that comprises that at least one of a parameter and image obtained from the sensor.

13. A data acquisition device as recited in claim 5 , wherein the data acquisition device further comprises a web server, the processing device being configured to send the message via email.
