A shunting protection device based on tdcs information

Abstract

The invention discloses a shunting protection device based on TDCS information. The shunting protection device comprises ground equipment and vehicle-mounted equipment, wherein the ground equipment iscomposed of a TDCS interface server arranged in a railway head office, a ground platform arranged in a railway bureau, a railway comprehensive information network and a wireless communication network. The vehicle-mounted equipment is composed of a vehicle-mounted mainframe unit, a wireless receiving unit, a train position obtaining unit and display terminals. The ground platform communicates withthe TDCS interface server through the railway comprehensive information network; the train position obtaining unit communicates with the ground platform in a wireless mode; the wireless receiving unit is in communication connection with the ground platform through the wireless communication network; and the vehicle-mounted mainframe unit is connected with the wireless receiving unit and the display terminals. The train position obtaining unit calculates position information of a train to be subjected to shunting operation, and thus positioning in a station graph is achieved; and TDCS information is obtained through the TDCS interface server, by combining station basic data, train route information is generated, and after the train route information is comprehensively processed by the vehicle-mounted mainframe unit, shunting safety prompt and prevention-control are achieved.

Description

Technical field[0001]The invention relates to the technical field of railway transportation, in particular to a shunting protection device based on TDCS information.Background technique[0002]Shunting operation is a highly technical, demanding and complex task in railway transportation. Shunting includes train marshalling, dismantling, unhooking, and transfer of trains, pick-up and delivery, transfer, and transfer of vehicles, as well as the alignment, transfer, and entry and exit of locomotives. The quality, efficiency and safety procedures of shunting operations not only have a great impact on the completion of station unloading, shortening of vehicle staying time, and accelerating vehicle turnover, but also have a great impact on ensuring the safety of trains and the realization of train formation plans and train operations. The map and transportation plan are also directly related. Over the years, shunting operations have completely relied on human control, and accidents such as ...

Problems solved by technology

However, the system includes station ground equipment and on-board equipment, and each station needs to build a set of ground equipment, which is relatively expensive, and the ground equipment uses Windows operating system, which is poor in operation

In addition, the ground equipment does not adopt the "1+1 redundancy" architecture, and the reliability and stability need to be improved; the wireless communication uses a digital transmission station, which is limited by the transmission power of the station and the frequency points allocated by each station, allowing network access The number of locomotives is limited, etc. It can be seen that the real-time performance, safety and reliability of the system control need to be further improved, and the promotion and application still face certain difficulties.
