Abstract

A method for providing real-time visibility on a construction project includes steps of: attaching a low-frequency, ultra low-power, two-way transceiver radio tag to each construction material to be used in the construction project; storing data relating to the construction material in the tag; and reading the data from the transceiver of the tag by interrogating the radio tag with radio frequency interrogation signals.

Claims

1. A method for providing real-time visibility on a construction project, said method comprising steps of:

attaching a low frequency, ultra low power, two-way transceiver radio tag to each item of construction material to be used in the construction project, said radio tag comprising;

a tag antenna operable at a low radio frequency not exceeding 450 kilohertz,

a transceiver operatively connected to said antenna, said transceiver being operable to transmit and receive data signals at said low radio frequency, a data storage device configured to store data comprising identification data for identifying said radio tag,

a data processor operable to process data received from said transceiver and said data storage device and to send data to cause said transceiver to emit an identification signal based upon said identification data stored in said data storage device, and

an energy source for activating said transceiver and said data processor;

storing, in the data storage device of the radio tag, data relating to said construction material;

networking the radio tags; and

reading the identification data from the transceiver of the radio tag.

2. The method of claim 1 further comprising a step of:

storing, in the data storage device of the radio tag, data comprising a specification for the construction material on which the tag is affixed.

3. The method of claim 1 wherein reading the identification data comprises interrogating said radio tag with radio frequency interrogation signals at a low radio frequency not exceeding 450 kilohertz via said tag antenna.

4. The method of claim 3 further comprising a step of:

during construction, cross-checking actual placement of the construction material with a specification to determine if the placement is correct.

5. The method of claim 4 wherein the cross-checking is done remotely.

6. The method of claim 1 further comprising steps of:

attaching the low frequency, ultra low power, two-way transceiver radio tags to tools and equipment to be used in the construction project; and

networking the radio tags such that said radio tags communicate with each other.

7. The method of claim 1 further comprising a step of transmitting the identification data from the radio tag to a central data processor.

8. The method of claim 7 further comprising transmitting the data such that the data is viewable via a web browser.

9. The method of claim 1 wherein the storing step further comprises storing encrypted data.

10. The method of claim 1 wherein the storing step further comprises storing a unique identifier corresponding to the construction material, the unique identifier stored in the data storage device.

11. The method of claim 13 wherein the unique identifier is used as a key to access data about the construction material.

12. The method of claim 1 further comprising a step of:

receiving a status signal from at least one sensor located in the radio tag, the at least one sensor operable to generate a status signal upon sensing a pre-determined status condition.

13. The method of claim 12 wherein the pre-determined status condition comprises a sudden temperature increase.

14. The method of claim 12, further comprising steps of:

receiving a time signal corresponding to the status signal, said receiving step further comprising steps of;

receiving stored corresponding pairs of status and time signals as a temporal history of events experienced by the construction material; and

receiving the temporal history as a report.

15. The method of claim 14, wherein the step of receiving a time signal is performed automatically upon receipt by the transceiver of the status signal.

16. The method of claim 14 further comprising a step of:

emitting a warning signal upon receipt of the status signal.

17. A system for providing visibility for a building project, the system comprising a network of:

a low frequency networked radio tag attached to construction materials, said radio tag configured to receive and send data signals, the radio tag comprising;

a tag antenna operable at a low radio frequency not exceeding 450 kilohertz,

a transceiver operatively connected to the tag antenna, said transceiver configured to transmit and receive data signals at the low radio frequency;

a data storage device configured to store data comprising identification data for identifying the construction materials, and

a data processor configured to process data received from the transceiver and the data storage device and to transmit data to cause said transceiver to emit an identification signal based upon the identification data stored in said data storage device.

18. The system of claim 17, wherein the low frequency networked radio tags are attached to building tools and equipment.

19. The system of claim 17, wherein the identification data comprises an Internet protocol address, and the data processor is operable for communication with an Internet router using said internet protocol address, such that at least a portion of the identification data can be transmitted through the Internet router to be viewable through a web browser.

20. The system of claim 17, wherein the radio tag further comprises

at least one sensor operable to generate a status signal upon sensing a pre-determined status condition.

21. The system of claim 20, wherein another radio tag within the network is operable to receive the transmitted status signal through its transceiver and wherein the another radio tag is operable to respond to this signal.

22. The system of claim 20 wherein the transceiver is operable to automatically emit a warning signal at the low radio frequency upon generation of the status signal by the at least one sensor.

23. The system of claim 22, wherein the radio tag further comprises:
