Description

Description of the invention entitled:

"SYSTEM FOR DISTANCE ACQUISITION AND MONITORIZATION VIA TELEMATIC NETWORKS OF BIOMETRIC DATA IN THE SECURITY FIELD"

DESCRIPTION

Introduction

The posture maintained by personnel during work operations can be significant in detecting dangerous conditions in a broad sense in many areas.

For example, in the case of a robbery, staff are asked to either raise their hands or lie down on the ground. The reading of the posture of the torso or arms can be significant to indicate the condition of danger, even more reinforced if all the personnel present the same position.

Again, for example, it can be detected if a person is standing or fallen to the ground or if a person is in a state of alertness or unconsciousness: in this way, elderly people or people who drive vehicles can be easily monitored.

State of the art prior to this system

At present, no commercial solution is known that can allow the control of biometric data relating to the detection of the posture of subjects and, in particular, a system that processes, filters and integrates such data and is able to generate alarms, being able to propagate them on networks communication standard already in use.

This offers the opportunity to create devices which, by integrating into standard telematic networks, offer the possibility of monitoring the posture of subjects, in particular, the inclination of the limb, or of the part of the body, on which they are affixed.

The application of these devices in the field of anti-theft systems, for the control of the elderly and of vehicle drivers is certainly of commercial interest.

System description

Refer to figure 1.

The overall system consists of a standard wireless telematic network (for example, 802.11 -WiFi, 802.15.1 - Bluetooth or 802.15.4 - ZigBee) with or without related access protection systems (for example WEP, WPA-PSK, etc.), on which the detector devices are connected via a special network adapter.

These devices, depending on the application in question, may or may not be equipped with activation / deactivation systems (such as keyboards or displays) or auxiliary devices for sound acquisition or reproduction or other. However, in order to detect the posture (and in particular the inclination of the part of the body on which they are applied) they will contain an inclination detection system such as an ad-hoc device or an accelerometer.

More than one detection device may also be applied to a subject, and in particular, the telematic communication networks may be more than one (of the same or heterogeneous type).

A second device, present in the same telematic network or in another network connected to it (i.e. through a special router), consisting of a personal computer or similar device, will interrogate the various detector devices or in any case receive the data and, in case of anomalous situation, to be defined in the software depending on the application considered, to generate an alarm of various types (activation of telephone dialers, sending of sms, emission of sound alarm, etc.).

Detection device

The detection device (or "Detector") consists of a wireless adapter, a microcontroller or a DSP, a group of sensors and the necessary supporting electronics, see figure 2.

The microcontroller contains the program, and through it performs all the functions required by the device.

The wireless adapter, which may be, by way of example only, IEEE 802.11 (Wi-Fi), IEEE 802.15.1 (Bluetooth) and / or IEEE 802.15.4 (ZigBee), allows the system to connect, using any suitable security (for example WEP, WPA-PSK, etc.), to a telematic network in order to communicate on it.

At the present time, that is of the first version, the inclination sensor has been designed with two distinct modes:

• By means of a MEMS accelerometer on at least one axis, a more expensive solution but which also allows to detect movements (as they are small dynamic accelerations).

• By means of tilt switches, for example electrolyte or mercury, mounted with a certain inclination to each other, very economical solution.

For the anti-theft function, the presence of a keypad for entering the PIN was designed to activate and deactivate the detection functions.

In all application functions there are one or more buttons to generate alarms (for example, in the case of voluntary generation of an alarm condition).

In the future, other detection and data acquisition systems may be included, as well as displays and audio playback devices.

This device is expected to have an interchangeable lithium-ion battery, which guarantees about 10 hours of autonomy.

An example of application of the device are those of fig. 3 and fig. 4.

The sending of the surveys carried out can be made at regular intervals by the detector device or upon request of the data collection and analysis system.

Data Collection System

The data collection system is a computer software capable of connecting and controlling the functions of the detector devices.

The computer where the software will be installed can be dedicated to this specific function or not (in this case it is necessary that there are sufficient free resources to guarantee its regular operation) and be part of the same physical network where the detection devices are located or less (in this case it is necessary that there is a routing device, compatible with the types of networks used)

Its functions are to generate alarms in one or more of the following cases:

• An alarm button has been activated on a detector device

• The inclination of a certain number of devices signals an anomaly for more than a certain time (at most even one)

• A device is turned off (or the application system to the body part is unfastened) without entering the correct deactivation code (PIN)

• You lose contact with one (or more) of the detector devices

In the event of alarm generation, depending on the availability of the hardware present in the computer on which the software will be running, it will be possible to send SMS, make calls with a telephone dialer, activate a siren, etc.

Initial system

The system described here is being implemented using WiFi type network adapters and conventional prototyping technologies (in production it will be necessary to implement all the circuits with more suitable technologies that guarantee miniaturization and the reduction of production costs).

The initial field of application is provided as an anti-theft system, i.e. complete with keyboard for activation / deactivation and implementing a second deactivation code (PIN) generating an alarm but causing the detector device to behave locally exactly as if it were correctly deactivated (in so as to deceive any requests for deactivation in case a robber knows of the presence of the system).

Future developments

In the near future, plans are being made for the adaptation of devices in the field of monitoring the elderly and disabled (ie without keyboards) and subsequently for monitoring the conditions of drivers of special vehicles.

Furthermore, it is planned to use, together with the inclination detection system, additional biometric sensors capable of improving the effectiveness of the devices.
