IoT Data Logger for Rockfall Safety Solutions – Geobrugg GUARD

Project description

A simple, quick glance at the dashboard replaces the time-consuming and sometimes dangerous walk in the field: the Geobrugg GUARD is a smart device attached to the rope of a flexible net barrier. Waterproof and with a battery life of seven to ten years, it comes equipped with a selection of sensors to measure environmental and physical data. It transmits multiply encrypted measurement data via mobile radio to the cloud.


Key data and technical details

  • An autonomous IoT device for continuously capturing measurement data, such as the tensile force in a rope (DMS), corrosion and acceleration parameters, and environmental data.
  • Encrypted transmission of measurement data to a Google cloud (MQTT and Protobuf)
  • Can hold up in challenging environmental conditions:
    • temperature range of -30° to 80°
    • Waterproofed for rain & snow
    • Accelerations up to 200g
  • Battery life: 7 – 10 years

  • IoT data logger Geobrugg GUARD was developed over several project phases from conception to series production
  • Extensive field tests on network bars could already be carried out with the first functional samples
  • Manufacturing costs were optimized in the development stage
  • Device was industralized in collaboration with a manufacturing partner
  • System tests (environmental conditions, radio pre-tests, EMC lifetime, metrology and acceleration) were carried out
  • Design transfer through to production
