Abstract

Με το προτεινόμενο σύστημα επιτυγχάνεται ο αυτόματος χειρισμός των προβολέων και των φώτων πορείας οχήματος με ταυτόχρονη σαφήνεια στις αποφάσεις του ανεξάρτητα από τις διακυμάνσεις του φωτισμού του περιβάλλοντος. Το σύστημα περιλαμβάνει ανιχνευτές (φωτοαντιστάσεις ή φωτοτρανζίστορ), κυκλώματα ενισχυτών, ηλεκτρονόμων (Ι, ΙΙ, ΙΙΙ, IV) και ψηφιακών ολοκληρωμένων κυκλωμάτων τεχνολογίας TTL (μετρητές και λογικές πύλες). Οι τροφοδοσίες είναι 12V για τους ενισχυτές και τους ηλεκτρονόμους και 5 V για τα ψηφιακά ολοκληρωμένα κυκλώματα. Αν νύκτα κάποιο όχημα, με αναμένα τουλάχιστον τα φώτα πορείας διασταυρωθεί με κάποιο άλλο που έχει ανάψει τους προβολείς του και έχει το σύστημα αυτό, τότε όταν η μεταξύ τους απόσταση γίνει περίπου 100 μέτρα οι προβολείς του δευτέρου θα σβήσουν και θα ανάψει αυτόματα η μεσαία σκάλα. Αν όχημα, που έχει το σύστημα, κινείται σε επαρκώς φωτισμένο δρόμο οι προβολείς του πέφτουν αυτόματα στη μεσαία σκάλα. Στην περίπτωση αυτή λαμβάνεται υπ' όψιν και η ταχύτητα του οχήματος. Αν το όχημα που έχει το σύστημα ακολουθεί άλλο όχημα, που δίνει επαρκή φωτεινά σήματα με τα πίσω φώτα του, τότε για να μην ενοχλείται ο προπορευόμενος οι προβολείς πέφτουν αυτόματα στη μεσαία σκάλα όταν η μεταξύ τους απόσταση γίνει περίπου ίση με 15 μέτρα. Αν τα σήματα δεν είναι επαρκή ο οδηγός κατεβάζει ο ίδιος τα φώτα στη σκάλα των μεσαίων όπως θα έκανε και απουσία του κυκλώματος. ωWith the proposed system, the automatic handling of the headlights and running lights of a vehicle is achieved with simultaneous clarity in its decisions regardless of the fluctuations of the ambient lighting. The system includes detectors (photoresistors or phototransistors), amplifier circuits, relays (I, II, III, IV) and TTL technology digital integrated circuits (counters and logic gates). Power supplies are 12V for the amplifiers and relays and 5V for the digital integrated circuits. If at night a vehicle, with at least the headlights on, crosses another vehicle that has its headlights on and has this system, then when the distance between them is about 100 meters, the other's headlights will turn off and the low beam will automatically turn on . If a vehicle, which has the system, moves on a sufficiently lit road, its headlights automatically fall to medium beam. In this case, the speed of the vehicle is also taken into account. If the vehicle equipped with the system is following another vehicle, which gives sufficient light signals with its rear lights, then, in order not to disturb the person in front, the headlights automatically fall to low beam when the distance between them becomes approximately equal to 15 meters. If the signals are not sufficient, the driver himself lowers the lights in the middle ladder as he would do in the absence of the circuit. oh
