Description

Control method and system for molten iron intermodal railway port station Technical Field The invention relates to the technical field of intermodal transportation of molten iron, in particular to a method and a system for controlling a port station of an intermodal transportation railway. Background In intermodal transportation of molten iron, a railway special line is introduced into a port automation container terminal yard to carry out loading and unloading operations, and related facilities for train arrival, departure and automation loading and unloading operations are built in the port. The loading and unloading line of the port yard can independently finish train arrival and loading and unloading operations, and can also cooperate with rail receiving stations (harbor stations) around the port to finish the operations. At present, the daily loading and unloading operation amount of domestic ports is large, the operation efficiency is high, the operation safety level and the automation degree of a simple port are high. The dock operating system (TOS) is widely applied to ports, is core software for dock production, and is used for comprehensively scheduling operations such as container loading and unloading, loading, storage yard, port dredging and the like, and is also called as a 'brain' of the dock, so that the efficiency, safety and cost of dock operation are directly affected. However, compared with ports, the freight railway transportation scheduling and control system is still in a semi-automatic state, interconnection and intercommunication among professional systems are lacking, and more manual intervention is needed in the operation flow. Railway rolling stock enters and exits port railway loading and unloading lines, and has more conflicts in space and time with the operation of automatic loading and unloading equipment. This is in significant conflict with the need for multiple intermodal transport for efficient transport, safe and reliable operation. Based on the prior art, the automatic handover of the container transportation train is difficult to realize. Therefore, a novel control system is needed, the railway line resources and the line resources of the port loading and unloading areas are reasonably allocated and coordinated, automatic train handover is realized, the labor cost is reduced, and the working efficiency and the safety are improved. Disclosure of Invention The invention aims at the technical problem that railway line resources and port loading and unloading areas conflict with each other in the prior art. The invention provides a control method for a port station of a molten iron intermodal railway, which comprises the following steps: the TOS acquires train number, container number of each carriage and cargo information of the arriving train, and handles the train entering a loading and unloading yard to start receiving according to the condition of a container yard, the operation condition of the yard and the access condition provided by the interlocking control system; After the loading of a certain station in the loading and unloading yard is finished, the TOS sends a departure request to the estuary station dispatching system, and after the departure permission of the estuary station dispatching system is obtained, the TOS converts the loading and unloading operation mode into a train receiving and departure mode, and the loading and unloading operation of the loading and unloading yard is stopped. Preferably, before the TOS sends a vehicle receiving instruction to the interlocking control system, a vehicle receiving station track loading and unloading operation stop command is sent to the automatic loading and unloading system at the same time, wherein the automatic loading and unloading system feeds back a stop operation state to the TOS and sets reasonable and safe delay to ensure that the vehicle receiving is started after the operation is stopped and delayed. Preferably, the line fault checking system monitors the railway line fault condition in real time at the time of departure operation to the estuary station or receiving operation from the estuary station, if the railway line fault condition exists, the TOS is notified, and the TOS sends a command for stopping railway operation through the interlocking control system. Preferably, when receiving a vehicle from an estuary station, the TOS compares the processed route with the station video before sending a vehicle receiving instruction to the interlocking control system, determines that the route is free and has no obstacle, then the entrance guard is opened, after the entrance guard is opened, the interlocking control system processes the completion according to the route of the TOS instruction, finally opens a signal machine related to a loading and unloading line, the train enters the loading and unloading line, and after the train is stopped, the TOS gives a closing entrance guard command, and simultaneou
