Each Dynamate® has a dynamic triggering program built into its software which allows you to identify one or more Early Warning Units (EWUs), usually those closest to the blast epicentre, to act as the trigger source for other units. The dynamic triggering system also determines vibration and air blast sources to avoid false triggers caused by other blasts nearby.
Blast events can be triggered via several methods:
- Manual: by the Dynamaster® user
- Threshold: when air blast or vibration levels exceed a user-defined threshold
- External: generated by another Dynamate® station or compatible device
- Auto: Dynamate® continuously generates event files covering a user-defined period
- Integral: you set a threshold limit, but the software determines whether it’s an actual blast or a single peak caused by another phenomenon, such as rock fracturing.
Blast results are automatically collected from the stations, collated and made available within minutes of the blast.
With a ‘set and forget’ approach, once the unit is placed in the field and switched on, data triggered by your specified parameters — for example, air blast exceedances at a Dynamate® station or a low battery warning — is sent via GPRS, 3G or 4G communication to a central server where it’s uploaded to the website and sent to users by SMS and/or email accessible on any enabled device. Other communication methods such as satellites can also be employed.
