<p>The directional device for counting people by diffuse reflection is an elongated structure made of metal with an electrostatic paint finish and a removable front acrylic cover or a cover made of a similar material; with an approximate height of 1.60 metres and a width of approximately 14 centimetres and a depth of approximately 14 centimetres. This structure has the shape of a rectangular prism containing, in the interior thereof, a cavity which accommodates an electronic card which counts people and transmits the data obtained by means of four diffuse photoelectric sensors. It contains, at the height of the electronic card, a screen which makes it possible to display the data produced by the card. The directional device for counting people by diffuse reflection receives and transmits the data. It is installed in a very simple manner by means of a mechanical assembly. It is fed from 12 to 36 volt batteries and has a minimum energy consumption, avoiding the discharge of the battery feeding it.</p> |
