Definitions

  • the present invention relates to a device for detecting the presence and determine the direction of passage of mobiles for counting.
  • the term "mobile” applies as much to an object as to a living being.
  • Detection and determination of the direction of passage of mobiles is usually done at using a mechanical infrastructure such as turnstiles or gates, or optical systems with cutting of beams.
  • the turnstiles generally have three branches. One person crossing the turnstile turns it a third of a turn. This rotation constitutes the detection, and an external system can count the number of people who passed.
  • This device requires a large and expensive ground infrastructure. It causes a slowdown the flow of pedestrians having to pass the turnstile, by a bottleneck effect, and can only work in one direction of passage.
  • Another known device uses an infrared barrier, consisting of an emitting part and a receiving part placed opposite each other and thus forming a immaterial line. A pedestrian crossing this line is detected by the non reception of the beam light coming from the transmitter.
  • Infrared barriers need to be placed at a distance from the ground compatible with the size of the mobiles to be detected. Detecting people therefore requires place the barrier about one meter high, which requires supporting infrastructure. This arrangement of the sensor at one meter from the ground does not protect it from acts of vandalism.
  • FR-2 431 738 describes a detection device in which the reception elements must be inclined towards the detection zones, which requires adjustments during installation specific delicate, long and expensive, and is expensive to manufacture.
  • the invention aims to overcome these drawbacks and relates to a device according to the claim 1.
  • the device according to the invention is fixed to the vertical of the mobiles to be detected (ceiling by example), which does not require any infrastructure on the ground and makes it more safe from possible acts of vandalism.
  • it is in the form of a monoblock, thus not requiring two separate elements, unlike the infrared barrier. This provision does not generate slowdown in the flow of mobile flow.
  • the device includes a housing comprising firstly two transmitters (1 and 4) each having the function of emitting a beam towards a mobile by means of optical means, secondly a reception system consisting of two elements (2 and 3) capturing the beam reflected by the mobile passing through the detection zone via reception optics and, thirdly, electronic control elements transmitting (1 and 4) and processing signals received by the receiving elements (2 and 3).
  • the first and second transmitters (1 and 4), as well as the reception elements, are diodes infrared.
  • Electronic control of each transmission and signal processing element received by each receiving element comprises a clock (17) generating a pulse driving each emission element, an amplifier (18) amplifying the light signals generated by each receiving element, and a biomarker sampler (19) synchronizes with said clock to block the amplified signals and compare them with a voltage of reference by means of a comparator (20).
  • the device integrates two synchronized infrared transmitters and receivers allowing generate in the direction of passage of the mobiles two detection zones in space.
  • the existence of these two virtual detection zones makes it possible to determine the direction of passage of the mobiles by direct reflection.
  • the transmitting elements continuously emit light pulses. Resting, when no mobile is present, the receivers receive no signal. When a mobile passes through the sensor detection zone, this zone being between a minimum distance and at a maximum distance, it meets a first beam. This beam is reflected on the mobile and is detected by the first receiver. Continuing its movement, the mobile then cuts the second beam. The second beam is reflected on the mobile and is detected by the second receiver. The chronology of the light beams received makes it possible to determine the direction of passage of the mobile.
  • the device comprises two transmitters of the infrared diode type (1 and 4).
  • the light emitted by these infrared emitters is focused using an optical device of emission (5 and 7).
  • a mobile cutting the beam emitted by the first infrared transmitter (1) reflects this beam.
  • the reflected beam (10) passes through the reception optics (6) to reach the first receiving element (3).
  • a signal is then received by the first receiving element (3).
  • the mobile continuing its movement cuts the beam emitted by the second transmitter infrared (4), and reflects this beam.
  • the reflected beam (11) passes through the reception optics (6) to reach the second receiving element (2).
  • a signal is then received by the second element reception (2).
  • the signals received on the reception elements (2 and 3) make it possible to know the presence and the direction of passage of the mobile. If the first receiving element (3) receives a signal before the secondarily receiving (2), the mobile moves in a direction from the first element transmission (1) to the second transmission element (4). If the second receiving element (2) receives a signal before the first receiving element (3), the mobile moves in a direction from second transmission element (4) to the first transmission element (1).
  • the device according to the invention allows the detection of mobiles cutting the beam emitted by the first transmitter (1) over an area between a minimum distance (12) and a maximum distance (14). It allows the detection of mobiles cutting the beam emitted by the second infrared emitter (4) over an area between a minimum distance (13) and a maximum distance (15).
  • the maximum (14) and minimum (12) distances are determined by the focal length (16) of the reception optics (6) , the size of the sensitive surface of the first reception element (3), the distance (9) between the first reception element (3) and the axis of the reception optics (6), the distance between the transmission optics (5) and the reception optics (6).
  • the maximum (15) and minimum (13) distances are determined by the focal length (16) of the reception optics (6), the size of the sensitive surface of the first reception element (2), the distance (8) between the second reception element (2) and the axis of the reception optics (6), the distance between the transmission optics (7) and the reception optics (6).
  • the transmission elements (1 and 4) are driven by pulses supplied by a clock (17).
  • the pulsed light signals received by the receiving elements (2 and 3) are amplified by means of an amplifier (18).
  • the received signals are blocked synchronously to the transmission clock by means of a blocking sampler (19), to be able to be compared to a reference voltage in a comparator (20). The result of this comparison gives the output signal 1 and the output signal 2.
  • Figure 4 shows the timing diagrams of the output signals (output 1 and output 2) for a mobile passing in the direction of first transmission element (1) towards second transmission element (2).
  • Niche-shaped signals appear when the receiving elements are not receive more signal.
  • FIG. 5 represents the timing diagrams of the output signals (output 1 and output 2) for a mobile passing in the direction of second transmission element (2) towards first transmission element (1).
  • Niche-shaped signals appear when the receiving elements are not receive more signal.
  • the device can be provided with 2 reception optics, each being associated with a receiving element (2 and 3).
  • the main industrial applications of the device are in particular the detection and determination of the direction of passage of mobiles moving alone or in a group and in various places for counting. For example, this is the count of people entering and leaving a means of transport for people (metro, bus, train ...) or a public or private place, metering in particular of objects passing on a conveyor belt, counting of vehicles ...
