WHAT IS IT?

© 2020 Engineering USA, All rights reserved.

Smart Proximity / what it is

• Smart Proximity is a sensor-based platform that

helps organizations monitor, control and predict

potentially harmful behavior in the workplace.

• Smart Proximity operates in real time, sending

warning messages to workers and operators who do

not maintain appropriate safety distances.

• Smart Proximity enables reliable contact tracing and

contamination reporting, all while protecting

employee privacy and personal information.

• Smart Proximity helps ensure business continuity,

social distancing and worker safety in a post-

lockdown world.

Smart Proximity / how it works

• The solution ensures that a safe distance is maintained

between coworkers.

• Each worker is outfitted with a unique proximity sensor

(e.g. wristband, badge, card):

• If the distance between two proximity sensors is

below the safe distance, both proximity sensors

emit a warning (sound, light, vibration, etc.).

• This critical event data is recorded and sent to

the central platform. If workers maintain a safe

distance, proximity sensors don’t interact with

each other and no data is recorded.

SECURE DISTANCE

ALERT!!!

Connected sensors

communicate the

proximity data to the

gateway via Wi-Fi or

Bluetooth LE 2.4 GHz.

The field generated by

each proximity sensor is

at 13.56 MHz.

The server

anonymously stores

and processes

proximity data.

Proximity detection

can be configured

between 3.2-6.5 ft

with a ±10% error.

Contagion Communication

Smart Proximity relies on several

components in order to constantly

monitor safety distances, enable

communication between sensors,

carry out advanced analytics, and

store and protect data.

• No sensitive information is stored

on the platform.

• Only unique identifiers and their

relations are stored, and they are

encrypted.

Proximity Gateway.Identifies an industrial grade IoT ready Edge device that

supports various communication protocols. BLE and Wi-Fi

have been assumed as available in this specific solution.

The coverage of the area is limited to the communication

technology used and the type of antenna.

Proximity Sensor. The wearable sensor, engineered in a bracelet, badge or

similar type of item, creates a system able to interact with one or more sensors

located nearby. The sensors interact with each other by sending and receiving

proximity information. When two devices are "visible" to each other, they provide

real-time warning indicators (sound, led light), asking the operators to maintain a

safe distance. The alert function does not need to interact with the center, since it

is autonomously activated by the device.

• By means of the Wi-Fi network and BLE, the information collected by the

device is sent to the proximity gateway, which forwards it to the platform.

• The device contains an ISO 15693 receiver/transmitter and uses a 13.56 MHz

carrier with low power consumption.

• The device sends diagnostic information to the platform, such as the battery

level.

• The device is equipped with a button battery, whose life varies from 3 to 5

days. The device can be recharged via USB or induction.

• The device is able to detect other nearby devices within a range of up to 6 feet

(1.5 meters) with a +/-5 inch (10 cm) margin of error.

• The device features a memory that stores data and information in case of

communication failure with the proximity gateway.

• The device does not require any anchorage points, significantly reducing the

infrastructure costs.

Smart Proximity / the technology

The proposed technology is suitable for industrial environments, because it is

unaffected by infrastructure noise and critical operating conditions.


Smart Proximity / the technology

Proximity Sensor Configuration.

The connection to the plant Wi-Fi network takes place on

entire batches of devices using the ISO 15693 proximity

antenna of such devices (reception).

The Wi-Fi network configuration parameters are

transmitted by means of a desktop application in the

Smart Proximity platform and an appropriate ISO 15693

(transmitting) antenna with adequate power connected to

the computer’s USB port.

The solution allows you to connect and configure

thousands of devices in minutes.

*Note: ISO/IEC 15693 is an ISO standard for vicinity cards, i.e. cards which can be read from a greater

distance as compared with proximity cards. Such cards can normally be read out by a reader without being

powered themselves, as the reader will supply the necessary power to the card over the air (wireless).

Smart Proximity / distance monitoring

Accessible via a web-based interface from any device, the

Smart Proximity platform enables you to monitor

distancing between workers in real time.

• You can monitor worker distancing in real time from

anywhere.

• Sensors will gather data even if connection to gateway

is lost, ensuring full reliability.

• Authorized access to history of all user behavior.

• Send notifications to personnel about issues to enable

immediate intervention.

• Trigger automatic alarms (light, sound, vibration) to

notify workers of unsafe behavior in real time (optional).


Smart Proximity / proximity analytics

Part of the central platform, the Smart Proximity Analytics

module graphs sensor proximity relations over time and

enables automatic contact tracing and reporting.

• The Table shows all contact events of a selected user per

day, including time and duration of each event.

• The Timeline shows all contact events of a selected user

per day, including time and duration of each event,

chronologically.

• The Matrix visually maps events between all users and

business groups, so you can identify high-risk behavior

on a larger scale.

• The Tree, Flat Tree and Circular Tree formats show how

a virus spreads, starting from one infected user. Contact

tracing can be established for 3 or more levels of

contamination.

Smart Proximity / contact tracing

• Smart Proximity Analytics

shows you how a virus

spreads, starting from one

infected user.

• If a worker informs the

company of contamination, a

report can be produced to

identify who they have been

in contact with during a

specified time frame (e.g. last

30 days), and must therefore

be quarantined.

• Contact tracing can be

established for 3 or more

levels of contamination.

Smart Proximity / proof of concept example

Preparatory activities to be performed by the customer (estimated time 1 h):

1. The customer should have a SMART PROXIMITY GATEWAY computer (physical or virtual) available,

which can connect to Internet in order to access the public SMART PROXIMITY INTEGRATION.

• IP address: 91.109.56.13, port: 5672 (and from May 18, 2020 port: 5671 – which will replace port

5672), using TLS (Transport Layer Security), i.e. protected connection.

• As an alternative to the Internet connection, the customer can set up a VPN to our Smart

Proximity Integration, but this is a more complex and slower process.

2. The customer needs to configure a fixed IP address and a TCP port (e.g. 5000) on the SMART

PROXIMITY GATEWAY in order to be able to communicate with the sensors.

On-site activities with Engineering (estimated time 1-3 days):

1. Engineering team will install software on the Smart Proximity Gateway in the plant,

2. Engineering team will configure WiFi connection parameters in the sensors. For this purpose, the

customer must provide the company WiFi network configuration parameters.

3. Engineering team will run the functional tests alongside with the customer.

4. Engineering team will provide a quick training session on the solution for the customer.
