CE4 Commander System - DetNet South Africa

The new CE4 Commander System from DetNet is a superior advanced blasting system and is easy to use, ensuring the best blast, on time, every time.

System components

CE4 Commander

This is a multi-purpose device that is used as a Bench Commander, Repeater and Base Commander, and it controls the entire blast.

Limits user interface through: automatic detonator detection, testing and fast programming.
Wirelessly controlled by the CE4 Tagger or tablet.
Up to 10 Commanders can be deployed for a single blast using long distance RF communication from a blasting point.
It has four channels that can connect up to 400 detonators, giving a total capacity of 1600 detonators per Commander.
By verifying the voltage, it can blast through high levels of leakage.
Boasts a unique and robust design, with a built-in long-range antenna, that can handle the harshest mining conditions.
The blast is initiated with contactless NFC (Near Field Communication) BlastCards.

CE4 Tagger

The CE4 Tagger is a leading innovation from DetNet and the best of its kind in the industry.

Tests leakage and troubleshoots the bench before leaving.
Single device on the bench tagging; can test up to 400 detonators at a time.
Scratch proof glass screen provides excellent visibility.
User alerts engage multiple sensory formats: tactile (vibration), audible (speaker) feedback and visual alerts through high-bright LEDs.
GPS enabled to aid in detonator trouble-shooting.
Excellent battery management technology and standard USB charging.
Wireless control of Commander to execute arm & fire.

4G Detonator

The new generation 4G Detonator is a fully programmable electronic detonator that is suitably tailored to fit all types of blasting operations. The design has evolved from the remarkable safety principles of the 3G detonator.

Redesigned Application Specific Integrated Circuit (ASIC) with 15 times more memory, which allows the storage and tracking of identification numbers.
Delay time and unique ID is fed directly into the detonator during on-bench tagging.
Verification of sufficient firing voltage at the furthest detonator, before the user presses the fire keys.
Down-hole wire length and other critical information is stored in the expanded non-volatile memory during detonator assembling.

Software Interface

The Tablet connects wirelessly to the bench Commander and becomes the user interface with bigger & more readable information.
The Tablet enables a full colour graphic interface.
You can download and view the full detonator list.
You can access the full blast design with a helicopter view and blast plan simulation.
Consolidate planned versus actual tagged list during fault-finding.
Execute the firing command.

Deployment Method

The system offers 3 deployment methods.

Plan Mode

Pre-designed ViewShot 3D blast plan which contains the location and timing is downloaded from PC to the CE4 Tagger. The user can define a tagging path that creates a detonator list in the sequence of tagging which is suitable for large scale blasts. The tagger writes the unique ID and timing into the detonator. The Tagging path is flexible allowing adjustment of the plan during tagging and the insertion of new blast holes.

Basic Mode

The Basic tagging option is offered where the delay is entered onto the tagger when tagging the hole.

Advanced Mode

The Advanced mode includes more functionality than the Basic mode as it allows for multi primed holes, location assignment and time incremental settings.

DGPS

High accuracy DGPS (Differential Global Positioning System)

The DGPS is a high accuracy (sub one meter), new addition to the CE4 Commander blasting system. The market leading CE4 Commander system has been further enhanced with the DGPS technology to accurately detect blast hole positions.

High accuracy differential GPS will revolutionize the deployment and tagging of the 4G detonators for surface mining. Potential human error with regards to incorrect blast hole identification or incorrect delay assignment is practically eliminated. Apart from eliminating potential human error during deployment this new feature enables autonomous detonator tagging and /or blast hole logging.

Features

Using the “Plan Mode” the CE4-Tagger automatically detects the blast hole location using the GPS co-ordinate from ViewShot 3D and automatically assigns the correct delay to the detonator as per the blast design.
The tagging process does not need to follow a specific tagging path.
When drill rigs are not equipped with GPS logging, the DGPS Tagger can be used to accurately log the blast hole positions.

Benefits

The CE4 Commander DGPS system is a ground-breaking technology advancement which:

Eliminates potential human error by semi-autonomous tagging of blast holes essential to improve blast outcomes.
Ensure accurate tagging of blast holes to improve blast outcomes.
Easy, reliable and fast deployment to speed up the blasting process.
Allows for future fully autonomous (robotic) deployment & tagging.
Find-a-det, ability to locate and track any det from the list.
