Definitions
- the subject of the present invention relates to a device for capturing attendance, in particular energy independent and / or connected and / or communicating, its use, as well as a method for implementing this device in a passageway.
- Counting devices in particular for people, generally seek to obtain the greatest possible measurement accuracy.
- the state of the art is rich in teaching as to propose means for determining the direction of passage of the entities counted, distinguishing the nature of the entity (living being, object, vehicle, etc.) in order to discriminate the entities not wanted.
- the introduction of narrowing necks which are intended to organize the entities in a row which is easier to count is not desired. Indeed, this last step has the disadvantage of slowing the passage.
- the state of the art has increased the number of counting means arranged on a passage space to "screen" the area considered.
- WOOl / 88858, US4000400, FR2644269, US2018046860 illustrate this type of implementation.

- the various electronic elements constituting this device as they are described are very energy intensive, particularly for continuous use.
- other systems known in the state of the art use 24 V DC power supplies with currents of the order of 2.7A which, given the high operating power required due to the emission for example of infrared radiation, can only be fed continuously. Such systems cannot be seriously autonomous in energy in view of their operating needs.

- a magnetic element for example a magnet adapted to come to stick by magnetism to said at least one element conducting magnetism such as the case fixing screw.
- Clause 11 Use of the device according to any one of clauses 1 to 9 to count living beings and / or moving objects, said device being preferably used for rental or temporarily and / or nomadically.
- Clause 12 Method for counting living beings and / or objects in transit in a passage space, characterized in that the method comprises at least one device according to any one of clauses 1 to 9, said passage space preferably being segmented into passage plots to place several of said devices in the different plots thus delimited so as to increase the counting accuracy.
- FIG. 1 shows the general principle of counting. It can be seen that the device is placed here in a bottleneck making it possible to count more reliably the number of people (P) and / or objects passing through the counting field (C).
- FIG. 1A shows an example of a bottleneck where a device (D) according to the present invention is positioned.
- Figure 1B shows the illustration according to Figure 1 A with a passage of two people (P) in the bottleneck.
- FIG 2 shows the device according to the present invention broken down into these different elements.
- the housing (1) is shown; an optional seal (2); a Lresnel lens (3), the assembly (4) of the sensor with the Lresnel lens placed at a first end of a tube of suitable length so that at the second end of said tube is placed the passage sensor (5 ) in the focal plane of the Lresnel lens; (6) transfer unit (card) (eg SiPy); (7) battery holder (eg CR123); (8) electronic card of the management unit and processing where are also supported the storage unit (not shown here) and / or transfer, and the battery support (7).
- Figure 2 also shows the optional special case where two sensors (5, 9) are inserted in the same housing.
- the second sensor (9) is assembled in the same way as its counterpart (5) behind a second Fresnel lens (10).
- FIG. 3 represents the magnet switch having been developed specifically in the context of the present invention.
- the hall effect sensor (CH) the communication card (CC), a representation of the magnetic field (CM) generating the hall effect, the magnet (A).
- the magnet (A) attached to the case by magnetism (for example to a head of the case structure screw)
- the Hall effect sensor no longer detects the magnet and sends a signal to the management and processing unit.
- the latter can then come out of a standby state and the counting begins, for example by an information message sent by the transfer unit, if necessary, and / or by the sending of a signal to an LED. visible from the outside of the housing.
- the process is reversed and the management and processing unit can then go into standby mode, possibly accumulated by a last sending of signals by the transfer unit, if applicable.
- the other units (such as the transfer unit) can of course also go into low power standby mode.
- a device according to the present invention was created using the following parts:
- card is structured around the microcontroller
- Example 2 device tested
- the device according to Example 1 recorded 1,248 return trips.
- the sensor recorded 990 round trips.
