Abstract

The invention concerns an infrared connection device using infrared rays for transmitting data from various electrical appliances to a remote data processing unit where they are handled. The infrared rays pass through a series of infrared wave guide tubes where they can be subjected to modifications of direction, or power amplifications, through optical or electronic means so to reach the data processing unit undamaged, even in the presence of a long and discontinuous trajectory. The absence of electric wire, or optical fiber in the infrared circuit facilitates mounting and maintenance of the various appliances integrated in the system developed by means of connectors similar to those used in the protective cladding of electrical circuits, or in hydraulics. Said data transfer mode by infrared radiation also enables novel uses, in particular through the use of an infrared electronic barcode capable of being remotely modulated specially designed for moving vehicles.

To improve the propagation of waves Infrared especially on long trips, one can place the various tubes in a suitable gas atmosphere, or even rarefied, or under vacuum. Thermal insulation of these Tubes Infrared Waves Guide can be useful to increase their performance in the transmission of information.

Other features and advantages of the invention will be described in particular embodiments, reference being made to the following examples:

Example 1: SCANNER COLOR - Figure 6 -

If you want to control the color variations of my area (S), simply properly place more infrared photocells reflections (preferably diffuse) (K1 ... K8) distributed preferably obliquely across the width of this surface (S), the information will be transmitted through one or more devices Connecting to Infrared (DC1.1, DCI2 ...) to one or more of Treatment Units

Information (UT1, UT2, ...). Continuous monitoring of this area can be done either by moving the various photocells (Kl, ... K8) mounted on a movable support, or by scrolling through this surface ( S) (with respect to the photoelectric cells (K1, ... K8) fixed.

Example 2: ELECTRICAL DOMESTIC. Modern electrical installations separate power circuits circuits controls, checks and / or protection; these are made by means of a low-voltage electrical circuit (24 N) acting on the electromagnetic relays arranged in units of commands and controls to equivalent of information processing units that can be disposed in one or more locations of dwelling. We can replace low voltage electrical circuits by one or more devices Connecting to Infrared.

Example 3: THE CONTROLS OF ELECTRICAL INSTALLATION AND CONTROL IN ALL TRANSPORT VEHICLE - Figure 7 -

The Infrared device connector can advantageously replace electrical circuits controls and checks in all transport vehicle (plane, train, car, coach, bus, truck, etc.). The information from several devices (fig7-index K1, .... K6) of a control box (ignitions headlights, parking lights, heating of the rear window, etc ...) can pass through a single tube Wave Infrared Guide (TGI) to reach one or more processing units of information (UT1, UT2) determining the controls and / or checks and / or desired views (cf. page 2, paragraph 4). The device has the following advantages: reduced weight (important in aviation), ease of installation and maintenance, reduced cost, and avoidance of fire by short circuit.

Example 4: RAIL SIGNAL.

The device connection Iiifrarouge is able to ensure a good transmission of information devices located along the tracks to a moving train, and vice versa to ensure the correct transmission of information devices arranged in the train to fixed installations located along these routes. The Barcode Electronics described on page 5, paragraph F, possibly associated with a Barcode mechanics to transfer the moving train all the characteristics of rail signaling, including the names of stations, signals the position and switches, speed limits, etc. .. the train itself may send ground all necessary information to ensure the proper conduct of his career, such as his identification number through a barcode Identifier that will be received on the ground during the passage of the train. As noted on page 5, paragraph F, the vertical-Bar Code along the railway line will be very well intercepted by trains, and easily installed; it is also possible to install horizontal-Bar Code at the caténers. Similarly, EAN code can be installed on the sides of locomotives and wagons, and / or on their roofs.

Example 5: ELECTRONIC BAR CODES ASSOCIATED WITH OR MORE BAR CODES MECHANICAL.

The Barcode Mechanical means the object of detection, and the Barcode Electronics indicates the state in which the object is located at the time of detection by a transport vehicle in motion. The Barcode Mechanical and Barcode Electronics can be intercepted by a single tube concentrator placed on the vehicle, in relation to these bar code, provided that they are in alignment with the path of the vehicle; can have several EAN code at levels that would be intercepted by various tubes Waveguide Infrared Hubs and / or enlargers, whose information would be managed in one or more units of information processing (UT) in order to increase the informative capacity EAN code. The distance between each of the segments of the EAN code, the nature thereof (electronic, mechanical or electronic-mechanical) and the width of each of them can contain all the relevant information to be transmitted. Conversely, they can be placed on-Barcodes vehicles, the tubes Waveguide Infrared enlargers and / or

Hubs responsible intercept can be placed on the floor or on other transport vehicles, eg on trains.

Example 6 POSITIONING A TRAIN ON ITS ROUTE

By placing along the tracks of milestones indicating via a barcode distance that has been traveled since the originating station to the destination station, various intercepting these convoys barcodes can accurately know their position at all locations meet these terminals; the distance between two successive coded terminals is measured by the rotation of the wheels. In this way, the actual position of the train at every instant can be stored and transmitted by radio waves to the train located upstream or downstream thereof. If the distance between trains is too low, drivers will be notified by alarms that can cause automatic slowdowns, even to stop the train in question.

Example 7: switcher INFRARED - Figure 8 -

In the guide transport vehicles on the ground, in a colored line by means of infrared photocells, it may be necessary to have an infrared switcher consisting of several tubes Waveguide enlargers arranged in a line forming a connection infrared between a point common to the initial line guide and several other lines having different destinations that the guided vehicle shall borrow; Ignition Infrared Sections (Fig.8-index Sel, Se2, Se3) adequate ensure the guide link between the origin point and the destination.

Example 8: RADIO TRANSMISSION.

Radio signal (SR) can be converted to infrared signals which, thanks to the device connection Infrared (DCI) are sent to one or more processing units of information (UHP1, UHP2) where they will be converted into sound signals by via high Speakers.
