Abstract

An electronic blasting system (10) comprising a plurality of hardware components (12.1 to 12.n), wherein at least two of components of the plurality of hardware components (20, 26) are adapted to communicate with each other over short range radio link (30)

Claims

1. An electronic blasting system comprising a plurality of hardware components including a blasting machine and at least two electronic detonators, wherein at least two components of the plurality of hardware components are adapted to communicate with each other over a short range wireless radio link in which the maximum distance between the at least two components for effective communication to take place is about 10 meters, wherein the at least two components are adapted to automatically communicate with each other over the short range wireless radio link as required when the components are brought into proximity with each other by formation of a wireless personal area network among the at least two components.

2. A blasting system according to claim 1, wherein the at least two hardware components are selected from hardware components that will not be consumed/destroyed when the electronic blasting system is employed in a blasting process.

3. A blasting system according to claim 1, wherein communication between the at least two hardware components is uni-directional.

4. A blasting system according to claim 1, wherein communication between the at least two hardware components is bi-directional.

5. A blasting system according to claim 1, wherein the at least two hardware components communicate with each other using Bluetooth™

short range communication protocol.

6. A blasting system according to claim 1, wherein the at least two hardware components communicate with each other using IEEE 802.15.4 short range communication protocol.

7. A blasting system according to claim 1, comprising only two components that are adapted to communicate with each other over the short range wireless radio link.

8. A blasting system according to claim 1, comprising three or more components that are adapted to communicate with each other over the short range wireless radio link.

9. A blasting system according to claim 1, wherein the at least two hardware components communicate with each other using IEEE 802.11, IEEE 802.15.4, IEEE 1451 (for linking sensors to transceivers) or Bluetooth™

short range communication protocol or using TinyOS operating system and platform targeting wireless sensor networks.

10. A blasting system according to claim 1, comprising multiple wireless networks, each wireless network comprising at least two hardware components that are adapted to communicate with each other over short range wireless radio link.

11. A blasting system according to claim 10, wherein hardware components within the same wireless network are adapted to communicate with each other over the short range wireless radio link as required on an ad hoc basis when the components are brought into proximity with each other.

12. A blasting system according to claim 11, wherein the at least two hardware components communicate with each other using IEEE 802.11, IEEE 802.15.4, IEEE 1451 (for linking sensors to transceivers) or Bluetooth™

short range communication protocol or using TinyOS operating system and platform targeting wireless sensor networks.

13. A method of communicating data in an electronic blasting system comprising a plurality of hardware components including a blasting machine and at least two electronic detonators, the at least two hardware components of the plurality of hardware components being adapted to automatically communicate with each other over a short range wireless radio link in which the maximum distance between the at least two components for effective communication to take place is about 10 meters when the components are brought into proximity with each other, which method comprises forming a wireless personal area network among at least two of the plurality of hardware components and communicating data via the wireless personal area network.
