Abstract

Digital communication system for monitoring structural integrity of a building and sensor therefor. The system includes a sensor that communicates structural integrity information to a gateway via a digital communication link. The digital communication link is preferably a bidirectional wireless link that supports packetized data transfer between the sensor and the gateway. Via the digital communication link, the sensor reports numerous types of structural integrity information upon interrogation by the gateway and may initiate transfer of structural integrity information interstitially upon an alarm threshold being surpassed.

Claims

a sensor coupled to the building;

a gateway; and

a digital communication link communicatively coupling the sensor and the gateway,

wherein the sensor awakens from a power-conserving sleep state and at least one of collects information respecting structural integrity of the building and reports information respecting structural integrity of the building to the gateway via the digital communication link.

2. The system of claim 1, wherein the digital communication link is a wireless link.

3. The system of claim 1, wherein the digital communication link supports packetized data transfer between the sensor and the gateway.

4. The system of claim 1, wherein the sensor reports information respecting structural integrity of the building to the gateway at least periodically.

5. The system of claim 1, wherein the sensor reports information respecting structural integrity of the building to the gateway interstitially upon an alarm threshold being surpassed.

6. The system of claim 1, wherein the information includes moisture content information.

7. The system of claim 1, wherein the information includes information reported through interrogation of the sensor by the gateway.

8. The system of claim 1, wherein the information includes information reported through execution on the sensor of a direct memory access (DMA) read command issued by the gateway.

9. The system of claim 1, wherein the sensor is embedded within one of a wall, roof and floor of the building.

10. The system of claim 1, wherein the gateway is disposed within the building.

11. A sensor for monitoring structural integrity of a building, comprising:

a sensing element adapted to collect structural integrity information;

a radio element adapted to transmit structural integrity information to a gateway via a digital communication link; and

a processing element operatively coupled with the sensing element and the radio element and adapted to regulate supply of power to at least one of the sensing element and the radio element based on at least one of a structural integrity information collection time and a structural integrity information reporting time.

12. The sensor of claim 11, wherein the digital communication link is a wireless link.

13. The sensor of claim 11, wherein the digital communication link supports packetized data transfer between the radio element and the gateway.
