Matrix to bring Maestro’s Plexus PowerNet to US mining market

Matrix Design Group is to introduce Maestro Digital Mine’s Plexus PowerNet™ networking system to the US market following the signing of a distribution agreement between the two companies.

Plexus PowerNet, the first coaxial-based gigabit network, provides both data and power over a single cable, according to Canada-based Maestro. The system delivers a high-speed, low-latency digital communication network that provides PoE+ power to Access Points, cameras and any other IP-based devices, it says.

The Plexus PowerNet coaxial cable carries both power and network connectivity, eliminating the need to run both fibre and power to new network devices. The system can also extend a fibre-optic-based system from the fibre patch panel at any level as needed. Plexus PowerNet eliminates the need for costly outside fibre-optic contractors and can be installed and maintained by any mine personnel, Maestro says.

Chris Adkins, Sales/Business Development, Matrix Design Group, said: “For a mining application, Maestro gives mines the ability to have high-speed data and power without the technical and time constraints of running a fibre network to the face of the mine. Of course, the maintenance requirements of fibre are complex, but Maestro has reinvented the high-speed data network, allowing delivery of real-time data and power combined into one durable coaxial cable that’s easy to install, maintain and repair.”

The Plexus PowerNet is a backbone network system that can be used in mines with or without a fibre-optic network, Maestro says.

“Supporting existing underground infrastructure, Plexus provides network connectivity to new and existing IIoT devices and automation technologies,” the company said. “It enables the digital mine and connected worker for: autonomous and tele-remote vehicles; telemetry to drills, loaders and support equipment; support for short interval control and connectivity to tablet and smart devices; IoT sensors, such as environmental and seismicity; Voice over IP; augmented reality; asset tracking; PoE+ based IP cameras and PoE+ LED lights for paste fill; and PLC connectivity. Plexus is an enabling technology for the digital mine.”

Michael Gribbons, Co-founder and CEO, Maestro Digital Mine, stated: “The collaboration with Matrix Design Group is an essential part of expanding our reach into the US market with a team that understands the value of our digital network solution and how it aligns with the mines in the area. Bringing digital solutions, such as the Plexus PowerNet, online enables worker safety, increased production and reduced costs; all of which are vital to Maestro and Matrix.”

Maestro Digital Mines’ Zephyr AQS leaves its mark at CIM convention

Maestro Digital Mine has used the backdrop of the CIM Convention and Exhibition, in Montreal, Quebec, to launch its latest digital industrial internet of things (IIoT) solution, the Zephyr AQS™.

Maestro’s Zephyr AQS is a compact, low cost environmental air quality monitoring station for underground mines. It is an IIoT device that connects directly to an industrial network without the requirement of adding an expensive and complex programmable logic controller (PLCs) and several analogue-based instruments, the company said.

“Since it is a digital device, not only are the real time environmental conditions reported back to surface via a single ethernet connection, but all the advanced diagnostic data is available too, assuring maximum uptime,” Maestro said.

Michael Gribbons, Vice President Sales and Marketing, Maestro Digital Mine, said at the launch event: “The Zephyr AQS was developed to satisfy 75% of all the air monitoring requirements of a modern mine. Airflow rate, airflow direction, gas levels, barometric pressure and wet/dry bulb temperatures can be measured in real time and, now, affordably.

“The Zephyr AQS is designed for any mine aiming to increase production, improve miner worker safety and reduce energy by monitoring and controlling ventilation air in an underground operation. The first step of working to control ventilation is the requirement of measurement. Only then can you start to understand and drive value to increasing production by getting the miners back to the face quicker and safer. Or, reducing the energy demand by providing enough ventilation air to the areas of the mine that need it and reducing air to the non-working areas of the mine.”

Like all Maestro solutions, the Zephyr AQS is a fully digital solution that can be plugged into a network switch without the requirement of PLCs, PLC cabinets and all the associated wiring, terminations, software and complex labour for integration into the network, the company said.

“Based on direct customer feedback, Maestro’s digital products save mining companies, on average, 40-60% of capital expenditure compared to conventional monitoring solutions,” Maestro said.

“All Maestro solutions are provided with lifetime, free firmware updates. The full savings to mining clients is in the range of 70-80% over the full life cycle with no hidden hooks or costs to bear in the OPEX maintenance cycle.”

The new Zephyr AQS air quality station features three fully configurable sensor inputs that can be freely mixed and matched according to the customer’s requirements. Like the Vigilante AQS™, the Zephyr AQS will be configured through built-in webpages similar to that of a home network router, according to the company.

All the sensors connected to the Zephyr AQS electronics are digitally supported by the way the Zephyr AQS communicates over the mine’s network using standard network protocols. Maestro fully supports both of the two most popular network communication protocols – Modbus TCP/IP and EtherNet/IP™. Alternately, the Zephyr AQS offers on-board analogue outputs (3 x 4-20 mA) and two relay outputs to tie into legacy systems.

David Ballantyne, Vice President of Development and Technology, Maestro Digital Mine, said: “The Zephyr AQS is considered the baby sister of the Vigilante AQS. Both provide plug and play sensors and both are fully digital. However, the Vigilante AQS supports seven plug and play ports versus three for the Zephyr AQS. The Vigilante AQS also provides four complete Proportional – Integral – Derivative control loops to allow it to run autonomously in the event of network failure. It can also integrate up to 24 RTD sensors used in primary fan and booster fan applications.”

The Vigilante AQS was created to solve 100% of the applications for mine ventilation monitoring and controlling, Maestro said, however solving all the applications with a single device adds extra costs for most of the simpler requirements.

Maestro has supplied over 120 mines globally with this equipment. “We recognised that a lighter version would be adequate for many of the mines price sensitive markets such as Latin America and Africa,” it said.

Maestro has 100 units sold, pre-delivery, from three existing hard-rock mining customers in Canada, the US and Spain.
