The invention discloses a railway interval broadband communication system based on an EPON (Ethernet passive optical network) technology, optical fiber call column devices, a center device and station devices which are used for the broadband communication system as well as a method for realizing railway interval broadband communication by utilizing the devices. The railway interval broadband communication system comprises at least one center device, multiple station devices and multiple optical fiber call columns, wherein the center device comprises a network switch and a trunking gateway, the network switch is connected with a bearer network by virtue of a first network interface, the network switch is connected to an external network or device by virtue of the trunking gateway; and the multiple station devices are arranged along a railway and are connected to the bearer network by virtue of second network interfaces; and the multiple optical fiber call column devices are respectively connected to at least one station device by virtue of a unidirectional or bidirectional optical fiber branch and are respectively provided with an interface used for connecting an interval communication terminal device. The communication system in the invention can be compatible with the existing cable interval communication service, and the targets of broadband-interval communication and broadband communication on the whole railway line are achieved.
Description
technical field [0001] The present invention relates to a railway interval broadband communication system based on EPON network technology, and also relates to an optical fiber communication column device, a central device and a station device used in the broadband communication system, and also relates to a method for utilizing these devices to realize railway interval broadband communication The invention belongs to the technical field of special railway communication. Background technique [0002] After long-term construction, my country's railway system has built a complete and independent railway communication network covering the whole country. However, at present, inter-rail communication (including tunnel emergency communication) still relies heavily on copper cables laid along the existing railway, and the means of communication are relatively backward. [0003] like figure 1 As shown, in order to meet the requirements of inter-rail communication, various copper c...
