YieldPoint Inc.

We are committed to explore novel technologies that can enhance the value proposition for monitoring of geotechnical and structural projects. Our mandate is to deliver products that where possible disrupt the established practices for geotechnical engineering, many of which have existed for 50 years. We leverage Internet of Things core technologies related to sensors, micro-controllers, wireless telemetry (Bluetooth 5) and LTE-M/NB IoT, and micro-satellite backhaul of data to the cloud. As instruments and telemetry become more integrated, power consumption decreases, reliability improves and cost decreases.

YieldPoint’s advantage is to enable projects operating on a limited budget, to install more instruments that can autonomously stream richer datasets that will be analyzed using intelligent data management platforms to enable better design and construction decisions. Our instruments are easy and fast to install, vulnerable lead-wires are eliminated, individual readings are tagged with the instrument ID, and the transmitted data values are in SI units and fully calibrated. All components including data-backhaul gateways are battery powered and do not require instrument configuration. A smart digital architecture reduces instances of human error allowing engineers and technicians to focus on their geotechnical challenges.

The transition to this inter-connected vision involves deep collaboration with other vendors and service providers in the space. YieldPoint pledges to be receptive to integration opportunities, and to use our deep in-house electronics and embedded expertise  to be nimble in meeting our customer’s requirements.

Typical applications include:

Ground movement monitoring

  • Extensometers for precision monitoring of hard rock
  • Civil extos for monitoring subsidence in soft rock above tunnels
  • GMMs for measuring convergence in potash and salt mines
  • Crackmeters for monitoring individual cracks and interfaces
  • Tiltmeters for monitoring angular deformation of structures
  • Crown Pillar Monitoring
  • Backfill Barricade pressure monitoring

Reinforcement monitoring

  • Optically instrumented rebar bolts with 1.25mm spatial resolution
  • Digitally instrumented rebar bolts
  • Instrumented 7-wire stand cable
  • A solution for monitoring self drilling bolts (dSDB)
  • The world’s only instrumented Split-set bolt
  • Instrumented fore-poles for large civil tunneling projects
  • Tieback monitoring downtown Toronto.

Geo-environmental monitoring

  • Thermo-strings for mining in frozen ground
  • VW sensors and interfaces for monitoring stress and pressure
  • VW interfaces for water-level monitoring
  • Digital Piezometers for monitoring water pressure.
  • HID cells for stress change monitoring
  • Temperature monitoring for deep mining
  • High resolution (1.25mm) optical thermal monitoring
  • Pressure cells for monitoring Pastefill barricades

The YieldPoint Catalog

YieldPoint digital instruments are based on our proprietary d-tech embedded architecture. Every instrument has an on-board micro-controller which performs tasks such as signal processing, reporting a unique sensor ID, and conversion to real world units. The end-result is a ‘Plug-and-Play’ ecosystem  comprising  instruments, data-loggers, telemetry, and network gateways which aggregate readings to a cloud database.

More Powerful ARM microcontrollers enable the integration of  on-board digital signal processing with  Bluetooth 5  wireless telemetry  to create wireless/digital  instruments that we refer to as the BluTech solution. Blutech devices run for years on internal batteries while beaconing their readings every few seconds.  In addition, up to 30,000 readings can be buffered  on the instrument itself and any Blu-tech gateway in range can receive  extended advertising packets from up to 16 Blutech  instruments of any variety, and backhaul them to the cloud database over Wifi, LTE-M or a micro-satellite network.  Consequently,  the established doctrine  for   monitoring system design  based on  instruments, multiplexers, dataloggers and telemetry is disrupted  by a new generation of  smart instruments.

More highly  integrated solutions means that the solution has never been more reliable! and at the same time, the cost of providing real time monitoring solutions for geotechnical projects has never been lower!


VantagePoint Geotechnical Platform

As low cost telemetry makes real time monitoring of geotechnical instruments a reality at most mines, the volumes of data generated by various monitoring systems have exceeded the capacity that can be handledby spreadsheets. Even standard SQL databases can begin to bog down.

VantagePoint is a geotechnical data platform (GDP) for the aggregation and visualization of geotechnical data. The platform is powered by a fast NoSQL database with a user-friendly API called DataPoint. The web-based visualization tool provides a responsive experience that encourages the user to develop cause-and-effect relations between instrument data, operational mining activity (Blasting events) and Seismic events.

As data accumulates in the system the opportunity exists to apply higher order analytics. Thus YieldPoint is actively developing +VantagePoint to help users unlock more value from the data generated through their instruments.

The solution can be configured using a cloud architecture or an on-site virtual server. Costing is scaled to the number of instruments and conducting a trial is a minimal expense. Pleases call today to so that you can take the pain out of data visualization.

In July 2022 YieldPoint released a new version of VantagePoint with new features including an improved Alarms module.

 


Case Study: Pillar recovery at Platosa Mine, Mexico

Authors: Samuel Freitag, Francisco Rodriguez, and Denis Flood

May 1, 2019

At Platosa Mine in Mexico YieldPoint dExto’s were used to monitor the back during the recovery of pillars. According to Samuel Freitag, the lead author, when the work was presented at the CIM conference(2019):

‘YieldPoint’s high resolution extensometers allowed us to monitor very small deformations. At first I thought that deformations less than a few mm were just noise, but because they appeared on multiple instruments and were synchronized with blasts we began to recognize and benefit from the high precision of these instruments”.

Working with consultants and researchers for the Colorado School of Mines, the project team at the mine was able to safely and confidently remove targeted pillars.
