All-optical transmission scheme for the entrance and exit of expressway toll booths

 

Highway toll stations are generally distributed with multiple entrance and exit toll booths, and each toll booth has the same data signal transmitted to the station-level management computer room. The current on-site transmission mode is multiple equipment optical transceivers: such as video signal, network signal, switch signal, intercom signal, telephone signal, control data signal and other transmitting optical transceivers, which are transmitted to the station-level computer room through multiple optical fibers to receive multiple optical transceivers. With so much signal transmission, the chassis and wiring channels of the basic equipment become more and more congested, causing a series of problems such as serious interference of working signals, unstable transmission data, and difficult construction and maintenance. To this end, Hua Tiancheng launched a professional toll station all-optical fiber solution to completely solve the increasingly serious dilemma of the above highway toll stations.

 

Rich interfaces and multiple transmission services: A single device integrates multiple service signal interface inputs of toll booths, and only needs single-core optical fiber transmission to the station-level computer room output. Such as toll booth video, intercom, audio, Ethernet, the type and number of signal interfaces can be increased according to actual conditions.
