Abstract

L'installazione di comunicazione è utilizzabile in particolare fra veicoli circolanti su un binario ed almeno un apparecchio fisso. Essa comprende un emettitore-ricevitore su ciascun veicolo e, sul suolo, molte stazioni ripetitrici fisse di emissione-ricezione 12 ripartite lungo la traiettoria dei veicoli ed in collegamento con l'apparecchio fisso. Le stazioni ripetitrici 12 sono collegate in catena con l'apparecchio fisso 14 e ciascuna comprende un demodulatore di segnali ad iperfrequenza ricevuti dall'emettitore di un veicolo, un organo di misura del campo elettromagnetico corrispondente ed un comparatore fra il livello di campo locale ed i livelli di campo comunicati tramite le stazioni ripetitrici adiacenti, ed inoltre un organo di decisione che autorizza la trasmissione di informazioni provenienti dal veicolo verso l'apparecchio fisso e/o l'emissione verso il detto veicolo solo tramite quella delle stazioni ripetitrici che riceve il campo più elevato.The communication installation can be used in particular between vehicles running on a track and at least one fixed device. It comprises an emitter-receiver on each vehicle and, on the ground, many fixed emission-reception repeater stations 12 distributed along the trajectory of the vehicles and in connection with the fixed apparatus. The repeater stations 12 are connected in a chain with the fixed apparatus 14 and each comprises a demodulator of hyperfrequency signals received by the emitter of a vehicle, a measuring device of the corresponding electromagnetic field and a comparator between the local field level and the field levels communicated through the adjacent repeater stations, and also a decision-making body that authorizes the transmission of information from the vehicle to the fixed device and / or the emission to said vehicle only through that of the repeater stations that receives the field higher.
