## CPC

- F42D 1/05: Electric circuits for blasting
- F42D: BLASTING (fuses, e.g. fuse cords, C06C5/00; {for obtaining fluid from wells E21B43/00; for mining or quarrying E21C37/00; for making tunnels or galleries E21D9/006}; cartridges F42B3/00)

## Abstract

A mesh network controller for remote control of devices such as remote firing devices. The controller includes remote firing devices which have a relay capability that allow a controller to communicate with remote firing devices beyond the range of its direct communication. This is accomplished by a signal being relayed from RFDs to RFDs with the signal going in two directions.

## Claims

### Claim 1

A wireless control system for remote firing devices, comprising:
a controller unit comprising a transmitter and a receiver of wireless signals, and an input port for defining RFD control instructions, and control logic and indicators for connecting to multiple RFDs in interconnected communication;
two or more RFDs, with each RFD with a connection to an explosives detonation device, a receiver for receiving signals from a controller or another RFD, and a transmitter for sending information to said controller or to other RFDs; wherein said controller can communicate with at least one RFD, and that RFD can communicate with at least on other RFD, and so on, so that said controller can control multiple RFDs through wireless connection with a single RFD.

### Claim 2 (depends on 1)

The wireless control system of claim 1 in which said indicators show which RFDs are under the control of the controller.

### Claim 3 (depends on 1)

The wire control system of claim 1 in which said input port allows a user to set detonation time delays for each of the RFDs under wireless control of the controller.

### Claim 4

The wireless control system of claim which further comprises a handshake protocol and pass off protocol, so that communication with the controlled RFDs can be shared with another controller, either through the first controller, or through a signal passed from an RFD to the first controller, so that the controlled RFDs can be managed by the second controller.

### Claim 5 (depends on 1)

The wireless control system of claim 1 in which the controller may control additional assets other than RFDs, selected from the list consisting of RFDs, drones, X ray sensors, x ray sending units, and PAN firing devices.
