Worker distancing, contact tracing and attendance controlTracer

Use cases

Contact Tracing
Tracer is a system designed primarily for monitoring the distance between operators and tracking their contacts, particularly in environments where safety, compliance, or operational efficiency is crucial.
When two devices come closer than a set threshold, the contact is recorded by the devices.
Disable alarms
This system allows to deactivate alarms thanks to a simple architecture:
a fixed device is installed near where the alarm is active. When a wearable device of the staff approaches the fixed one, the alarm is disabled.


Real-time and offline path monitoring
it allows verification that operators are following specific routes, such as security patrols or cleaning services, both in real-time and offline.
This is possible by installing fixed devices along the route that are gradually recognized by the operators' wearable devices. The proximity of the wearable and fixed devices is recorded, and consequently the actual passage of the route can be verified.
Association of operators and machinery
it enables monitoring the use of machinery by operators, making it possible to track who used a particular piece of equipment and when.
this is possible thanks to the installation of a fixed device on the machinery. When an operator's wearable device approaches, the approach and any dwell time are recorded.

Architecture

Tracer has a simple and intuitive architecture, centered around a wearable device (typically a SafeX). If the goal is to implement a contact-tracking system, the only required device is the wearable tag.
However, if you want to develop a path-monitoring system or a system to deactivate alarms in specific areas, you also need to install beacons at specific locations. The wearable tag scans these beacons when the operator approaches, confirming that the person wearing the device has passed through that particular area.
A similar logic applies when tracking machine usage: a beacon is placed on each machine, and when the operator gets close, the wearable tag scans the beacon, recording the interaction.
All proximity data (between SafeX devices or between SafeX and beacons) is recorded by the device throughout the working day.

LocateBLE architecture is based on three main components: BLE tags, BLE locators, LocateBLE software with Positioning Engine and APIs.
BLE tags move within the localization area and continuously broadcast a specific BLE advertising packet.
Fixed BLE locators (constituted by BLE gateways or any other fixed device with BLE scanning function) are installed at known positions inside the localization area. Depending on the environment, BLE locators may have omnidirectional or directive antenna, and can be installed on ceiling or on walls. Each BLE locator receives the signal from BLE tags, and computes RSSI.
BLE locators are connected on a local network (Ethernet LAN is suggested for reliability, but WLAN option is available as well) to a local server where LocateBLE software is installed. LocateBLE is designed as middleware platform, with its proprietary positioning engine (BPE, BlueUp Positioning Engine), web interface for management and monitoring, and integrated open APIs for seamless integration in high-end application software.
Ways to download recorded data
There are three main ways to download and view the data:
– SafeX Tracer Manager App (mobile): app that allows you to download the data at any time.
– SafeX Tracer Kiosk App (tablet): when the device approaches the tablet, the app recognizes the wearable tag and automatically downloads the data. This solution can be installed at the exit of the workplace to collect data from each passing device. The data can then be reviewed offline at the end of the day, for example.
– Tracer Gateway: works with the same logic as the SafeX Tracer Kiosk App, but is a physical device that can be placed at the exit of the workplace to collect data from devices passing through.

Components

SafeX
SafeX is a wireless electronic device that is worn by people.
SafeX is an active device, equipped with a battery, capable of autonomously transmitting and scan information (unique identifier and any status information, such as battery level).
Beacons
Fixed beacons can be installed at fixed reference points to develop applications for route control, machine usage control, alarm deactivation.


Tracer apps and gateway
The applications dedicated to the Trace system, such as the Tracer Gateway, allow you to collect data recorded in real time by the devices and download them at the most appropriate time.
Components
Tags

Asset tags and wearable tags are wireless electronic devices that are applied to assets or worn by people to be tracked.
Tags are active devices, equipped with a battery, capable of autonomously transmitting information (unique identifier and any status information, such as battery level) to the locators, using standard BLE advertising packets. Energy-saving modes are implemented for increasing battery life, based on tag motion status.
Locators

Fixed locators are installed at fixed reference points and receive BLE signals from the tags.
BlueUp gateways are used as standard locators but the system is able to support any kind of BLE scanner device with communication APIs.
