Embodiment Construction

[0019] It will be described and illustrated below in conjunction with the accompanying drawings of the present invention.

[0020] The present invention includes a receiving module 102 and a conversion module 104. The receiving module 102 is connected to the data signal output end of the station through an optical fiber cable 101. The receiving module and the conversion module are connected by optical fibers. The conversion module is connected to the interval user terminal equipment through wireless communication.

[0021] The receiving module adopts a passive optical device.

[0022] The conversion module is a chargeable portable device.

[0023] The conversion module includes an optical transceiver module, a main control module connected to a power supply, and a wireless router. The optical transceiver module and the main control module are connected through a parallel-to-serial conversion circuit, and the main control module is electrically connected to the wireless router....

Abstract

The invention relates to an optical call column which can provide wireless access to voice, data and images between a user in a railway section and a station. The optical call column is composed of receiving modules and conversion modules. The receiving modules and the conversion modules of the optical call column are respectively connected through optical fibers. The conversion modules are connected with user terminal devices in a wireless communication mode. The terminal user in the section can conduct both-way communication with the station through an optical interface provided by the optical call column. The conversion modules are rechargeable portable devices.

Description

technical field [0001] The invention relates to a communication device used in railway sections such as railways and urban rail transit, in particular to an optical communication column in railway sections. Background technique [0002] The railway section call post is a communication optical cable or cable terminal set on both sides of the railway line between two stations, with an interval of 1.5-2km. Temporary voice and data communication access for railway line inspection, maintenance, emergency rescue. When in use, the on-site staff carry portable public fixed-line telephones or shoulder-mounted or vehicle-mounted data and video emergency equipment to connect the section call column cable terminals to the railway digital voice dispatching (digital adjustment) subsystem and data communication system. [0003] At present, the optical communication columns used in domestic railway intervals mainly use photoelectric conversion equipment, which are powered by fixed batter...
