1. Introduction

This document is aimed for customers and sales and represents the basic functionalities for the HxGN

MineProtect Personal Alert. It describes the technology used, the recommended applications and

limitations of the system.

The Personal Alert System (PA) is a pedestrian tagged personnel tracking system that utilizes the

latest Time of Flight technology in the Ultra-Wideband (UWB) to determinate with high precision

personnel position relative to heavy machinery and provides reliable protection even under conditions

of poor or no GPS reception.

2. Product Description

HxGN Mine Personal Alert is the first accident-avoidance device worn by field personnel that ensures

visibility around heavy equipment. Using the reliability and precision of Time of Flight technology in the

Ultra-Wide Band frequency, Personal Alert is integrated with Hexagon Mining’s Collision Avoidance

System (CAS) for a comprehensive warning solution.

It enhances the visibility of personnel and vehicles in dangerous situations, reducing accidents by

alerting about the presence of anyone working around heavy machinery in the CAS display.

Position, heading, and path are calculated using the CAS in the vehicle, which together with PA

accurately determine one or multiple surrounding pedestrian tags distances against the heavy

machinery. This distance is then compared against the configured detection zones to alert vehicle

operators and pedestrians in case of imminent risk.

The Personal Alert System (PA) provides the following main functions:

 Personnel Position Awareness: which shows the heavy machinery operators where personnel

within the detection range are located.

 Personnel Protection Alarms: based on the movement of the personnel and the heavy

machinery, it measures continuously the distance between machinery and pedestrian predict

potential close interactions generating visual within protection distances and in case of critical

danger audible and vibratory alarms to both heavy machinery operators and pedestrians to

avoid possible accidents.

 Close Interaction Reporting/Notifications: Every close interaction alarm will generate an alarm

that is transmitted to the monitoring/reporting server for immediate notifications or historical

reporting for trend analysis.

 Personnel Tracking: All data is wireless transmitted to the server, which allows the personnel

within range distance to a vehicle with CAS to be tracked on the Live monitoring web services.

 Incident Analysis: Pedestrian close interactions are logged in the on-board hardware, which

can be recreated for incident analysis.

FEATURES AND BENEFITS:

 Alert - Uses high-performance algorithms within the same proven approach of safety zones

from CAS, employing highly intuitive ascending visual, audible, and vibration alarms to help

drivers and pedestrians avert imminent accidents

 Minimize accidents - Reduce the risk of accidents involving personnel and vehicles in all areas

 Reduce Blind Spots - Time of Flight technology tracks all personnel around vehicles at all

times, and alerts operators and pedestrians with 360 degrees of protection at any speed

 Adaptable to site specific requirements: Tremendously configurable detection and alarming

zones, based on vehicle location and situation reduces many nuisance alarms in un-risk

situations

 In-Cabin Driver Detection - Strategically mounted anchor devices identify pedestrian entering

the cabin, reducing nuisance alarms

 Integration and scalability - Fully integrated with CAS and able to upgrade with FatigueMonitor,

and HxGN Mine VIS

 Using web-based reporting and analytics, supervisors can detect and correct unsafe operator

practices by analyzing information wireless transmitted (WiFi/GSM/LTE)

 Improve safety culture - With the enhanced reporting capabilities, unsafe behaviors can be

identified and strategically reduced by knowing the root cause

 Investigate – Black box recording and data transfer records, specifically detailed data such as

location, tag ID and traffic for incident investigation

 Increase usability and learnability - Fully integrated with CAS, operators interact with a single

user interface for all safety purposes, reducing training time

 Monitor remotely - WiFi or GSM connectivity allows wireless data transfer, status monitoring,

and remote support functions

 Reliable and precise technology - Time of Flight technology increases the detection reliability

under poor GNSS conditions or under roof scenarios with a 50 meters range and a 5cm

precision not degraded by the distance.

3. System Architecture

3.1. Overview

The Personal Alert (PA) is composed by the following components:

 HxGN Collision Avoidance System (CAS)

 PA Vehicle Anchors

 PA Pedestrian Tags

The Personal Alert, combined with the HxGN Collision Avoidance System (CAS) technology, makes

use of risk-based algorithms to differentiate between pedestrians which can lead to dangerous situation

and others which do not represent threats based on pre-configured parameters. This real-time analysis

and sophisticated algorithms will determine a possible risk level

and indicate it to the operator of the vehicle via the CAS LED display and the personnel in danger via

various alerting mechanisms on the Pedestrian tags.

All the alerts from the PA can be transmitted to the Control Room for reporting capabilities.

Hexagon Mining

The Personal Alert System (PA) consists of Vehicle Anchors and Pedestrian tags. The Vehicle Anchors

contain a UWB ranging radio, a powerful microcontroller for distance computations and a CAN interface

to transmit ranging information to the CAS. Pedestrian tags are wearable devices with high-capacity

Li-Ion batteries and integrated charging system, which also contain a UWB ranging radio and

microcontroller, as well as two RGB LEDs with dynamically adaptive brightness, powerful vibration

motor and buzzer for alerting. The devices communicate with each other using Time of Flight

Technology at UWB frequencies, and the Vehicle Anchors are connected to the Collision Avoidance

System (CAS) using a proprietary CAN protocol.

The distance and detection zone between each Pedestrian tag and each Vehicle Anchor on heavy

machinery is calculated by the Vehicle Anchors and transmitted to the CAS main unit. The information

is also transmitted back to each Pedestrian tags as a low power signal at frequent intervals (adaptive,

up to 4 times per second). The PA will provide visual awareness to both the heavy machinery operators

and the surrounding field personnel inside the configured detection zones.

When the PA determines a dangerous proximity to personnel, the CAS LED display gives the heavy

machinery operator a warning of the greatest danger at that moment, this is given by a visual

awareness with direction of the closest detected personnel and a buzzing sound, at the same time the

pedestrian tag also provides a visual alert, buzzing sound and a vibration alarm to the personnel

depending on the configuration.

3.4. System boundaries

Hexagon Mining Personal Alert system is responsible for the detection of personnel wearing a properly

functioning Pedestrian Tag representing a threat and provides the correct visual signs to the vehicle

operator via the CAS User Interface and the personnel wearing the Pedestrian Tag based on the

preconfigured danger areas on the configuration.

The Personal Alert system requires line of sight between the Vehicle Anchor and the Pedestrian Tags

to perform according specifications, if the Pedestrian Tag is in a part of the body that blocks the Time-

of-Flight signal from the vehicle Anchor it might not be detected if there are no reflecting areas on the

surrounding of the personnel. Hexagon Mining recommends locations that allow the Pedestrian Tag to

be seen from 360 degrees from the Vehicle Anchors like the shoulders, helmets or belts (On the side).

4. Main Features

4.1. Enabling Personal Alert and Geo-Fencing

Functionalities

In the default configuration Hexagon Mining Personal Alert is active mine wide. However, it is possible

to mute the visual and audible alarms, as well as to adapt the detection zones depending on area or

speed settings.

To achieve this, the Personnel Alert must be activated or deactivated only on the desired geo-fences

and up to the desired speed using the Areas configuration in the CAS vehicle Register.

4.2. Personal Alert Detection Zones

The detection zones are configurable distances around the Vehicle Anchors. When a Pedestrian tag

is detected by a vehicle Anchor in the immediate proximity around the vehicle it processes the location

of the Pedestrian Tag and its distance relative to the Vehicle Anchor. Within three different zones, the

PA system will react differently providing visual, audible and vibratory alerts to the vehicle operators

and personnel.

There are four possible danger zones that are configurable, and each one of them will represent a

different notification to users:

 Cabin Detection Zone: This zone represents the distance on where the vehicle operators are

usually sitting, all alarms within this distance are suppressed on both Pedestrian Tag and CAS,

as well as on other PA-equipped vehicles.

 Far Detection Zone: This zone represents the distance on where vehicle operators and

personnel would be visually warned about each other, showing the direction of detection on

the vehicle LED display.

 Near Detection Zone: This zone represents the distance on where both vehicle operators and

personnel are still warned visually, but with higher intensity.

 Close Detection Zone (Danger Zone): This zone represents the distance on where vehicle

operators and personnel are in danger of suffering from an accident, and all possible alert

mechanisms are used to invoke an action of the operator and personnel. An audible alarm on

the CAS LEDs will only be triggered if the personnel is within the danger zone and the vehicle

is moving below the PA speed threshold in the direction of the personnel.
