The present invention relates to a control access gate.
In particular, the present invention relates to a control access gate equipped with a floor sensing system apt to detect the presence of a user or an object within its field of detection.
Therefore, the present invention falls within the field of user/object detection within a control access area.
To date, there are control access gate equipped with a floor sensing system used in the detection of a user or object across the area of floor on which the sensing system is installed.
In the international application document“WO20181 1 1414A1” a“floor mat system and associated methods” is described.
In this prior art document, the floor mat system is equipped with a sensor configured to detect a set of attributes for any physical objects that pass over and come in contact with the floor mat. The sensors in the floor mat detects set of attributes associated with the physical objects such as shopping cart, the products contained in the shopping cart and the person pushing the shopping cart.
The sensor, can detect the moisture, temperature, weight and quantity of physical objects over floor mat.
However, these“floor mat systems” presents some problems in that they need high sensitive sensors for detecting the weight, pressure or temperature, to be able to differentiate between objects and with this comes high cost of production and maintenance.
The underlying problem related to this invention is to realize a control access gate equipped with a floor sensing system apt to detect the user/s or object/s within its field of detection effectively.
The principal purpose of the present invention is to provide a control access gate equipped with a floor sensing system which offers a solution to the drawbacks of the floor mat system described above.
Another purpose is to realize a control access gate equipped with a floor sensing system that is able to detect multiple users.
A further purpose is to realize a control access gate equipped with a floor sensing system able to differentiate between a user and his/her belongings example luggage. A Still a further purpose is to realize a floor sensing system that is cost effective in terms of production, installation and maintenance. Further characteristics and advantages of the present invention will be apparent from the following the detailed description of preferred but not exclusive embodiments of the control access gate equipped with a floor sensing system according to the claim 1 attached.
A control access gate 1 comprising a floor sensing system 10, for detecting presence of a user and/or objects installed on pavements or floors in control access areas, said floor sensing system 10 comprising:
- a substrate 2
- sensing device 3
- control unit 4
said sensing device 3 is installed bellow said substrate 2; said sensing device 3 is configured such that is in communication with said control unit 4;
characterized in that said sensing device 3 comprise series of capacitive sensors 31 , which are operable independently of each other, apt to create an area of detection 5 defined by capacitive field of said capacitive sensors 3, above said substrate 2 such that each sensor 31 is apt to send signal to said control unit 4 when triggered by the user and/or object.
Detailed characteristics of the floor sensing system according to the present invention are quoted in the corresponding dependent claims.
Ulterior characteristics and advantages of the present invention majorly results from the description of one form of preferred execution but not exclusive of the floor sensing system according to the present invention, illustrated by a non-limitative example in the accompanying drawings, in which:
- figure 1 illustrates a section view of the floor sensing system of a control access gate;
- figure 2 illustrates an isometric view of the floor sensing system of a control access gate;
- figure 3 illustrates the planes Z1 , Z2 of the floor sensing system of a control access gate;
- figure 4 illustrates a section view of the floor sensing system of a control access gate;
- figure 5 illustrates a section view of the floor sensing system of a control access gate in its general form.
It is noted that anything found to be already known during the patenting process is understood not to be claimed and to be the subject of a disclaimer.
With reference to the figures, the reference numeral 1 generally designates a control access gate 1 , for detecting the presence of a user/objects, having a floor sensing system 10. The floor sensing system 10 comprising at least:
- a substrate 2
- sensing device 3
- control unit 4.
The sensing device 3 is in communication with the control unit 4, preferably via wireless connection. However, the use of wires to connect the sensing device 3 to the control unit 4 is not excluded.
The substrate 3 is superimposed above the sensing device 3. The substrate 3 is fixed to the sensing device 3 preferably by fasteners such as bolts and nuts or screws or preferably glued onto the sensing device 4.
The sensing device 4 is able to create an area of detection 5 above the substrate 3 . The sensing device 4 is equipped with at least a plurality of capacitive sensors 31 , evenly distributed on a first plane Z1 . Each capacitive sensor 31 define a specific position Xa,Yb on the first plane Z1 , where X and Y represent X-Y coordinates on Cartesian coordinates system and “a” and “b” are number variables from 1 to infinity. Each of the capacitive sensor 31 is independent of the other and apt to send signal to the control unit 4, when triggered by a user and/or an object. In particular, each capacitive sensor 31 is able to generate a capacitive field C above the substrate 2. Collection of the capacitive field C form the area of detection 5. When a user/object goes on the floor sensing system 1 , the capacitive field C of the capacitive sensor 31 of the position he stepped is disturbed, these disturbance changes the capacitance of the sensor 31 . These changes in the Capacitive field C are communicated to the control unit 4. The control unit 4 is able to analyze the signals it receives from the sensing device 3 to understand whether its an object or a user that is located on the floor sensing system. The control unit 4 is able to map the individual positions of the capacitive sensor 31 are triggered to form the shape of the object placed on it or the user that goes on and compares these shapes mapped with a data base of the control access gate 1 , to detect if the shape mapped is that of a foot/feet of a user or an object such as bags. Also feet shape of animal pets are also registered in the data base. Thus, the floor sensing system 10 is able to differentiate between a human user or a pet.
This type of floor sensing system 10 can be used at control access gates 1 to prohibit multiple users. Thus when the control unit 4 detects at least 2 pairs of feet shaped mapping, it denies access to the users. However, when it detects a pair of pet feet and/or luggage shaped mapping in addition to the user feet shape mapping, it allows access. In other form of operation of the floor sensing system 10, when the pair of pet feet and/or luggage shaped mapping is not accompanied by a user feet shape mapping, the control access gate 1 denies access.
The floor sensing system 10, preferably, comprises a platform 7 on which the weight of the user and/or object can be supported. The platform 7 is installed above said substrate 2 and superimposed with said detection area 5, and installed in such a way that it does not interfere with the capacitive field C of said detection area 5.
Preferably, the platform 7 is made of glass, in particular fiber glass.
Preferably, the glass is a transparent glass or white glass. However, other glass colors are not exempted.
The floor system 10 , preferably, comprise a plurality LEDs 6, in communication with the control unit 4, installed below the platform 7, on a second plane Z2 superimposed above the first plane Z1 with inter-plane depth separation d, where d ranges from 1 -20cm.
The plurality of LEDs 6 are evenly distributed on the second plane Z2 such that each LED define a position Xa,Yb on the second plane Z2.
Each LED of said plurality of LEDs located in the position Xa,Yb on said second plane Z2 correspond to a capacitive sensor 31 located in the position Xa,Yb on said first plane Z1 .
When a capacitive sensor 31 in the position Xa,Yb is triggered, its corresponding LED is triggered on via said control unit 4.
Preferably, the planes Z1 , Z2 are imaginary.
Preferably the planes Z1 ,Z2 are physical planes.
This create a visual shape mapping on the floor sensing system 10. This visuals can be used as a first step of control to detect when multiple users are present in the detection area 5.
The LED, preferably, have a colored light, visible on a surface said platform 7, when triggered via said control unit 4.
Preferably, the plurality of LEDs (6) is integrated with the platform 7.
