How “failsafe” is EarthSub?
The product is constructed to military standards and utilizes the highest grade electronics. However, the best technology can experience mechanical and electrical failure.
In light of the critical early warning role in detection of landslides, washouts and structural health monitoring, EarthSub has a number of levels of “heartbeat” to ensure it’s connectivity and functional state. If a sensor loses contact with a site controller an alarm is triggered. If a site controller loses contact with the server software applications a further alarm is initiated to allow service personnel to check the installation.
To offset any data communications failure, the site controller is capable of triggering an analogue alarm that can be observed by passing maintenance or field personnel.
It is as close to a failsafe early warning system as is possible.
How rugged is EarthSub?
The hardware is designed to provide extreme rugged performance in remote deployments. The sensors are IP68 rated and can be fully submerged for aquatic monitoring of dam walls, harbour foreshore structures and oil drilling platforms etc. The sensor housing has been tested to over 1,000 tonnes of pressure and will operate in temperatures between -20C and 80C.
The site controller is IP65 and has similar temperature ratings and is of the same material strength. Cables where used, are industrial grade and can be fire resistant if required.
What are the components of an EarthSub configuration?
A basic EarthSub SENTINEL installation comprises a sensor, a telemetry and Edge computing node and a site gateway controller. The node has the additional ability to trigger an analogue alarm. The site gateway controller provides the “cloud” interface for any number of movement sensors and determines appropriate threshold levels for transmission of “cloud” data to minimise data volumes. As a result, the site gateway controller can send the collected data via optional forms of telemetry to the outside world for display and further manipulation.
How is EarthSub connected to the Monitoring Software Suite?
There are many communication options within the EarthSub solution. Individual sensors direct connect to their Node via a fireproof coaxial cable. The Node can direct connect to up to 4 sensors. The Node communicates with the Site Gateway Controller via LoraWAN. For truly remote installations; for example, the middle of a desert, the Site Gateway Controller can connect via satellite to the Dashboard software.
The Site Gateway Controller then passes data to the relevant dashboard software via direct ethernet connectivity, 3G/4G device, SMS interface or any IP protocol technology.
What direction of ground movement can EarthSub detect?
The EarthSub sensor can detect ground movement distance in millimeters; forward, backwards, left, right, up, down and can detect rotational movement for pitch, roll and yaw in degrees.
