BAI Best Alarm Illness

Elderly people who live alone or in the nursing homes, technicians who work on unattended plants such as electrical substations, water purification plants, radio links, inspectors of energy transport lines, etc.
Isolated work and life carry potential risks and therefore require a tool for the safety of people

Tonali E.A. proposes BAI (Best Alarm Illness), the system that automatically detects an illness condition of an operator active in the field and then sends a request for help on a voluntary basis or completely automatically (detecting prolonged immobility of the person).


There are many plants spread throughout the territory that require constant maintenance or repairs. In most cases, we are talking about jobs that require a single employee who has to work independently in isolated conditions. Company technicians sent to third parties for the maintenance of electricity or gas systems, workers in the operation of unmanned systems such as electrical substations, water purification systems, radio links, office cleaning workers who work outside hours, road haulers, night supervisors, inspectors of energy transport lines (power lines, gas pipelines), etc. There may also be opportunities to work in solitude in places that normally see the presence of numerous employees: control rooms of chemical plants, refineries or thermal power plants, warehouses, deposits, technical rooms, archives, etc. There are also situations in which the elderly find themselves alone in their own home or in the nursing homes. Loneliness is a danger that must be taken into consideration. Consequently, the most suitable means must be identified to ensure the remote control of the person's status and the immediate alarm signaling in the event of an accident, injury or illness in order to obtain the fastest possible intervention,.

BAI system presented by Tonali E.A. operates through dedicated devices

  • two transmission devices supplied to the operator (one primary and one spare, clone of the first) to send the message with or without its interaction

  • a receiving apparatus. The receiver forwards the signals to an intrusion control unit, even an existing one, through voltage-free analog connections using the relays present in the device. The intrusion control unit then sends a report to the remote surveillance Service Centers through the active security technological infrastructure.

The radio connection between the receiver and transmitter is established both Peer-to-Peer and through the use of a radio infrastructure (such as access points or repeaters). The bidirectional radio channel is full duplex with a safety mechanism on the reception of data packets and relative recognition ("acknowledge") to avoid false signals or the repetition of the same alarm.
The detection times of pre-alarms and automatic alarms (loss of verticality and absence of movement) are defined on the receiver and can be configured via the web server supplied with the BAI.
