Smart Proximity / what it is

• Smart Proximity is an integrated 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 distancing.

• 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

The proximity sensor communicates the proximity data to the gateway via WiFi or via Bluetooth LE 2.4 GHz.

Field generated by the proximity sensor at 13.56 MHz.

The proximity server anonymously stores and processes the proximity data.

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.

DATA PROTECTION


Smart Proximity / where we apply it

Smart Proximity helps ensure safe workplace behavior and worker interaction across a number of different settings and fields.

MANUFACTURING & AUTOMOTIVE PLANTS

CONSTRUCTION SITES

SUPPLY CHAIN, SHIPYARDS & WAREHOUSES

TRANSPORTATION HUBS & STATIONS

OFFICES & INDOOR AREAS


Smart Proximity / factory conceptEach operator has a proximity sensor.

The sensor communicates with the proximity gateway, reporting its own UID, the nearby sensor’s UID, the timestamp and the elapsed time.

As soon as one of the operators fails to keep a proper safe distance in a specific time frame, both sensors provide warning signals (vibration, LED, sound), notifying the operators to increase the safe distance. The proximity gateway

communicates the information to the proximity server, which creates a graph of relations and monitors the critical events in real time.

Proximity Gateway.Identifies an industrial grade IoT ready Edge device thatsupports various communication protocols. BLE or WiFihave been assumed as available in this specific solution.The coverage of the area is limited to the communicationtechnology used and the type of antenna.

Proximity Sensor. The wearable sensor, engineered in a bracelet, badge orsimilar type of item, creates a system able to interact with one or more sensorslocated nearby. The sensors interact with each other by sending and receivingproximity information. When two devices are "visible" to each other, they providereal-time warning indicators (sound, led light), asking the operators to maintain asafe distance. The alert function does not need to interact with the center, since itis autonomously activated by the device.

• By means of the WiFi network or BLE (depending on the device model), theinformation collected by the device is sent to the proximity gateway, whichforwards it to the platform.

• The device contains an ISO 15693 receiver/transmitter and uses a 13.56 MHzcarrier with low power consumption.

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

• The device is equipped with a button battery, whose life varies from 3 to 5days. The device can be recharged via USB or induction.

• The device is able to detect other nearby devices within a range of 6 feet (1.5meters) with a +/- 5 inch (10 cm) margin of error.

• The device features a memory that stores data and information in case ofcommunication failure with the proximity gateway.

• The device does not require any anchorage points, significantly reducing theinfrastructure costs.

Smart Proximity / the technology

The proposed technology is suitable for industrial environments, because it isunaffected by infrastructure noise and critical operating conditions.


Smart Proximity / the technology

Proximity Sensor Configuration.

The connection to the plant WiFi network takes place on entirebatches of devices using the ISO 15693 proximity antenna of suchdevices (reception).

The WiFi network configuration parameters are transmitted bymeans of a desktop application in the Smart Proximity platform andan appropriate ISO 15693 (transmitting) antenna with adequatepower connected to the computer’s USB port.

The solution allows you to connect and configure thousands ofdevices in minutes.
