Description
PROCESS AND DEVICE FOR DYNAMICALLY MEASURING A BODY TEMPERATURE, AND SYSTEM COMPRISING SUCH DEVICE The present invention relates to a device for dynamically measuring a body temperature, to a system comprising at least one of such devices and to a dynamic body temperature measurement method by means of such a system. As is known, especially in the current global health situation afflicted by the presence and rapid circulation of the COVID-19 virus, a careful and widespread detection of the presence of any febrile states in people becomes of vital importance, even more so when this control must be addressed to intended users to access sensitive environments, such as for example hospital and/or company environments and/or departments, or even rest homes, shopping centers, airports, clinics, means of mass transport, etc., in order to prevent contact with potentially infected people or, more generally, even sick with a simple cold or flu, with other healthy individuals.
Currently, thrs control can be carried out, for example at the entrances of hospitals, health or manufacturing companies and airports, by means of infrared thermometers or thermos-scanners: in particular, these instruments for real-time measurement of body temperature currently on the market are expensive devices that they increase the risk of gathering since their operation requires a time, albeit short, of parking in a fixed position in front of the device itself.
Therefore, object of the present invention is solving the aforementioned prior art problems by providing a device, a system and a process that allow overcoming the limits of what is currently proposed by the state of the art and thus resulting more dynamic, customizable and smart for the detection of the human temperature.
Another object of the present invention is providing a device, a system and a process that allow reducing the phenomena of gathering with advantages on the health and safety of people.

- FIG. 11 shows a screen of an APP belonging to the system according to the present invention.
Referring to FIG. 1 and 2, it can be noted that the device 100 for dynamic measurement of the body temperature of at least one subject according to the present invention comprises processing means 101 and:
- at least one thermal sensor 1, preferably of the contactless matrix type;
- at least one video camera 2, preferably of the optical type;
- at least one distance sensor 3, preferably of the ultrasonic type;
- at least one temperature sensor 4;
- at least one ambient light sensor 5;
- data transmission means 102, 103, said processing means 101 operatively cooperating with said thermal sensor 1, camera 2, distance sensor 3, temperature sensor 4, ambient light sensor 5 and data transmission means 102, 103.
With particular reference to FIG. 7 and 8, in which two possible and preferred embodiments of the system 200 according to the present invention are shown, and which are described below for greater detail, it is possible to note that the device 1 according to the present invention is based on at least one electronic card which uses processing means 101, such as for example a microprocessor / microcontroller, which manage the various sensors and actuators referred to above, as well as data processing and remote sending of the same by means of data transmission means 102, 103: the remote
connection of the device 100 can take place through a WI-FI wireless channel 102 or through a wired LAN connection 103 or through any other transmission means, foreseeable on the basis of the project and suitable for the purpose . Obviously, the device 100 according to the present invention can also comprise a power supply 11 of the electronic board which can use any form of power source 17 such as, for example, a battery, a power transformer or a
POE (Power Over Ethernet) .
The present invention therefore also relates to a system 200 for dynamic measurement of the body temperature of at least one subject comprises at least one device 100 according to the present invention such as the one described above and at least one barrier with crossing detection cooperating operatively with this device 100 .
For example, the barrier with crossing detection can comprise two infrared identification photocells 20 facing each other, constituting an infrared barrier consisting respectively of a transmitter 7 and a receiver 8 .
For example, as shown in FIG . 3, the system according to the present invention could also comprise at least one support structure 300 on
which at least one device 100 is arranged and in which the infrared identification photocells 20 are positioned to the right and to the left of the structure 300 itself.
Preferably, the support structure 300 has a defined geometry such as to optimize the viewing angle (Field of View or FOV) of the device 100.
For example, FIG. 4 shows the positioning of the support structure 300 inside a reception area (or any activity, public or private, which involves a minimum or even high flow of people such as commercial activities, airports, railway stations, ports, etc . ) .
FIG. 5 instead shows, for example, the system according to the present invention with the device 100 according to the present invention in a "naked device" form, i.e. without the support structure 300 inside the passenger compartment of public or private means of transport (such as trains, metro, ships, buses, etc. ) : in this circumstance, the installation is customized to the environment using Wi-Fi or Bluetooth identification photocells. The device 100 activated by photocells 20 is therefore positioned at the entrance to the doors.
FIG. 6 instead shows, for example, the system
according to the present invention without the support structure in one of its applications inside a reception area (or any activity, public or private, which provides for a minimum or even high flow of people as for e.g. commercial activities, airports, railway stations, ports, etc. ) : in this application, the device 100 can be installed at the top on a bracket or false ceiling and photocells 20 can be arranged in the lower part of the entrance.
The system 200 according to the present invention, as for example shown in FIG. 7, could also comprise at least one server 12 provided to receive and process the data detected and sent by the device 100 through Internet: the use of the server 12 therefore allows the simultaneous collection and processing of data from different systems 200 located in points different of the globe. The server 12 can therefore communicate the processed data to at least one final user connected through smartphone 13, fixed PC 14, tablet, smartwatch or any other device provided with data connection .
The system 200 according to the present invention, as for example shown in FIG. 8, may not provide for any connection of the device 100 to
Internet: in this case, therefore, the user connects himself directly to the data connection generated by the system 200 itself, receiving information in real time. Furthermore, in this configuration, the system 200 can provide a connection to a device such as monitor 16 or tablet 15 for an immediate display of the measured temperature, together with the projection of other useful information, such as the number of visitors ' accesses and exits, the detection of the day and time of entry.
The present invention also relates to a process of dynamic measurement of the body temperature of at least one subject by means of a system 200 such as that previously described.
The present invention therefore allows the dynamic measurement of the body temperature of a subject who is in a determined activation range of the system 200 by means of the method according to the present invention.
In particular, the process according to the present invention comprises the following steps:
- the distance sensor 3 continuously and cyclically returns a distance measurement of the subject who is in a range of action, for example a
range of 3m, the value of which is stored in the processing means 101;
- the processing means 101, and in particular the microprocessor/microcontroller, calculate the approach of a probable subject by evaluating the difference between two consecutive measurements taken at a regular time interval: this value allows for two different information: a) preparing a step for acquiring the thermal images necessary for measuring the temperature; b) identifying the travel direction of the subject in relation to the position of the barrier with crossing detection 2; 7, 8, in order to identify whether the passing subject is entering or exiting it: in the event that the subject is exiting the barrier, it is useless to acquire the thermal images as he is leaving the room. The travel direction is also useful for counting the number of people entering and exiting. Furthermore, the identification of the approaching direction can be used for the trigger of camera 2 for the exact identification of the subject. In this way, it is possible to associate the thermal image with the photo of the subject to avoid identification errors ;
- once it has been identified that the travel direction of the subject is in the direction of the barrier with crossing detection 2; 7, 8, i.e. "incoming", as soon as this subject crosses this barrier with crossing detection 2; 7, 8, to acquire a plurality of thermal images, preferably matrix, preferably as many as possible, by means of the thermal sensor 1, such images being able to be correlated to the shutter speed and one or more photographs of the entering subject by means of a video camera 2;
- storing each thermal image, preferably matrix, together with the photograph or photographs of the subject within a storage medium of the processing means 101, preferably for a minimum time necessary to complete the passage of the subject under analysis. Furthermore, at the same instant the process can comprise the step of providing for identifying both the ambient brightness through the ambient brightness sensor 5 and the ambient temperature through the temperature sensor 4.
For example, through the system 200 of FIG. 7, the method according to the present invention can further comprise the step of sending to the server 12 one or more of the aforementioned thermal matrix
images together with the photographs using the internet through the data transmission means 102, 103 of the device 100, or other means available: in this case, the process according to the present invention provides for a step of identifying the temperature of the subject which takes place in the server side option 12.
Alternatively, according to the configuration of the system 200 according to the present invention of FIG. 8, the method according to the present invention can further comprise the step of sending one or more of the aforementioned thermal matrix images together with the photograph or photographs directly to the device 15, 16 of the user: in this case, the method according to the present invention provides a step of identifying the temperature of the subject on board this device 15, 16, however requiring a higher computing power by the processing means 101.
In particular, the use of a process that exploits the potential of a server 12, such as that of the system of FIG. 7, allows a remote and timely setting of the individual devices 100 located throughout the territory, with the possibility of updating the method according to the present
invention itself, should this intervention prove necessary. In addition, the use of server 12 allows the management of a database for recording the data of interest, with the possibility of subsequent consultation, even after several days.
The system 200 according to the present invention can also comprise at least one computer program or application for smartphones and/or tablets that allows end users or administrative users to view the results of the processing by accessing the system itself through said computer program or application. for smartphones and/or tablets, such as APP or through the web platform, using mobile or fixed terminals 13 and/or 14.
The process according to the present invention therefore provides for the step of identifying the face of the subject under analysis and in particular the forehead of the same, in order to measure the temperature in the points of the forehead: the process according to the present invention therefore also includes the step of calculating, on these points, the maximum, minimum and average of these values. The value of the measured temperature, which can possibly be compared with a maximum reference threshold, is
equal to the average value measured on the forehead. The result of the comparison with the maximum threshold can then be used to detect any febrile states.
The process according to the present invention through of the system 200 can furthermore, in case of detection of a febrile state of the subject, comprise the following steps:
- setting off an acoustic alarm; and/or
- inhibiting the opening of a door manned by said system (200) ; and/or
- triggering a light alarm.
The identification of the human shape, and therefore of the face of the subject, takes place through the use of a constantly evolving database, generated by the same devices 1 located in the various points of the network. In addition to a step of facial detection of the subject, the process according to the present invention also comprises a step of correlation with the reference images, so as to center the same. After centering the image, always drawing from the database, it is possible to position yourself on the forehead. Measurement errors and problems due to a possible hot background that can confuse the shape are
completely eliminated by means of a further step of the process according to the present invention which provides for the use of a plurality of consecutive thermal photos, for example two or three, which being taken at different distances, they uniquely show the approach of the subject's silhouette which, therefore, is uniquely identified. With the same criterion of the use of subsequent images, it is also possible to envisage a step of the process in which to identify the main shape if the images contain several shapes placed at different distances.
The above described device 100, system 200 and process have been validated in the field by the Applicant in an experimental way using different real scenarios. For example, FIG. 9 shows a thermal acquisition without using the application of the identification step of the process according to the present invention. It is possible to highlight different shades of color used to represent the various temperatures, with evident values of higher temperature on the face (darker area) .
FIG. 10a and 10b show instead two examples of measurement using the process according to the present invention. These are two scenarios in which
there are two shapes , one of the two farthest from the main shape object of the temperature identification . The thermal images in the background constitute noise , so by applying the proces s according to the present invention, it is possible to extract only the temperature on the front of the main shape , as visible from the image , in which the measurement point is highlighted with a black dot .
FIG . 11 shows an example of a screen related to an APP developed for the 200 system which shows the main parameters of interest of the measure , easily usable even by non-expert operators .
The device , the system and the process according to the present invention therefore allow achieving the intended purposes by allowing :
- the dynamic measurement of the temperature in a specific area of the human body without the need for contact (nor for the subject to be stationed in a fixed point ) ;
- to monitor the flow of people with the possibility of viewing, remote management , geolocation ;
- the creation of statistics on the data relating to the flow of people (number of hourly,
daily, weekly, monthly, average passages, male/female sex recognition, etc. ) .
