The present invention will be described in more detail below.
The railway transportation automatic long-access system for the iron and steel plant area is mainly used for improving the automation level of the iron and steel plant area molten iron transportation route management. The automatic long-route system for railway transportation in the steel factory establishes a molten iron transportation process flow principle by analyzing production requirements of different molten iron transportation work types and empty tank heavy tank conditions and combining with production experience of a traditional molten iron transportation mode, calculates a set of perfect basic route configuration by utilizing a depth-first search algorithm, covers round trip routes among various work sites in the factory, and prioritizes a round trip route set. Each basic route is formed by sequentially connecting a series of unit routes according to the route travelling direction.
After the factory floor delivers a transportation task to a certain train unit, the railway transportation automatic long-route system of the steel factory floor judges whether the current work flow link of the train unit allows the long-route planning of the transportation task. After the permission is obtained, the system automatically plans a plurality of long routes for the train set according to the end point of the transportation task requirement, fully considers the influence of the process flow and the transportation efficiency, and selects the long route which is most suitable for the current working condition. The automatic long-route system for railway transportation in the iron and steel factory needs to acquire the positioning of the train set so as to lock the unit route where the tail end of the train set is located, and the unit route is used as the starting point unit route of the long route. After the automatic long-route system for railway transportation in the iron and steel factory converts the end point required by the task into the track section information, the unit route where the track section is located can be locked to serve as the end point unit route of the long route. The automatic long-route system for railway transportation in the steel plant area searches basic route configuration and calculates a turn-back route according to the unit routes of the starting point and the ending point to obtain an alternative long-route set, wherein when the turn-back route exists in the long-route, the automatic long-route system for railway transportation in the steel plant area determines the number of unit routes contained in the outgoing route according to the total length of the train set. In order to obtain the optimal long way, the railway transportation automatic long way system in the steel plant area performs long way pre-inspection. Before pre-inspection, the alternative long route set is arranged according to the priority in the basic route configuration from high to low, and the system starts to inspect from the long route with the highest priority to confirm whether the long route has ground, signal equipment faults and long-term occupation condition of route resources. If the situation is not found, the long route is output as the optimal long route, otherwise, the railway transportation automatic long route system in the steel plant area queries the sub-priority long route downwards in sequence until the optimal long route meeting the condition is output. The optimal long route can be intuitively displayed on a station diagram interface in a highlight route form and dynamically changed along with the running condition of the vehicle.
When the vehicle runs according to the selected optimal long-route, the railway transportation automatic long-route system acquires the current vehicle positioning information in real time, and monitors the condition of railway equipment and the condition of occupied route resources in the front route of the current vehicle. If any factor preventing the vehicle from advancing exists in the front route, the railway transportation automatic long route system in the steel plant area triggers an automatic change flow to plan a new route for the transportation task again, so as to avoid route obstacle and conflict. Factors that hinder the advancement of the vehicle include:
the railway transportation signal interlocking system is in a turning mode;
the forward route annunciator is abnormal in lighting signal or is extinguished;
the front approach annunciator is in a listing maintenance state;
the track circuit is in a hanging overhaul state;
the turnout is in a state of losing the meter or the turnout position is wrong;
the turnout is in a quarto state;
the turnout is in a hanging overhaul state;
the front route has the risk of route conflict;
there are other consist of non-destination parking spaces on the forward road that are occupied for a long period of time.
After triggering the automatic changing process, the railway transportation automatic long-route system in the steel plant area stops the opening process of the unit route in the original long-route. When the train set arrives at the arrival section of the last open unit route, the system takes the current position of the train set as a new starting point, and refers to the factor triggering automatic change to carry out long-route planning on the transportation task again. When all the alternative long routes can not meet the transportation production requirement, the railway transportation automatic long route system in the steel plant area feeds back the re-planning failure information to the display interface in time, and requires the intervention of a dispatcher to perform barrier removal operation or change task instructions and the like.
Those skilled in the art will appreciate that the systems, apparatus, and their respective modules provided herein may be implemented entirely by logic programming of method steps such that the systems, apparatus, and their respective modules are implemented as logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers, etc., in addition to the systems, apparatus, and their respective modules being implemented as pure computer readable program code.

The automatic long-route system for rail transportation in steel plant area according to claim 7, wherein the set of alternative long-routes is arranged with priority in basic route configuration from high to low before pre-inspection, and the long-route pre-inspection module starts to inspect from the long route with highest priority to confirm whether there is ground, signal equipment failure and long-term occupation of route resources on the long route;
if not, the long path is output as an optimal long path; otherwise, the sub-priority long routes are queried downwards in sequence until the optimal long route meeting the condition is output.
9. The automatic long-route system for railway transportation in the iron and steel plant area according to claim 1, wherein when the vehicle runs according to the selected optimal long-route, the real-time monitoring module acquires current vehicle positioning information in real time and monitors the condition of railway equipment and the condition of occupied route resources in the front route of the current vehicle; if any factor preventing the vehicle from advancing exists in the front route, the real-time monitoring module triggers the automatic changing module to request the long route planning module to plan a new route for the transportation task again;
after triggering the automatic changing flow, stopping the opening process of the unit route in the original long route; when the train set reaches the reaching section of the last open unit route, the long route planning module takes the current position of the train set as a new starting point, refers to the factor triggering automatic change, and carries out long route planning on the transportation task again;
when all the alternative long routes cannot meet the transportation production requirement, the long route planning module feeds back the re-planning failure information to the display interface in time, and requires the intervention of a dispatcher to perform the obstacle removing operation or change the task instruction.
10. An automatic long-haul railway transportation method for a steel plant area, characterized in that the long-haul planning is performed by the automatic long-haul railway transportation system for a steel plant area according to any one of claims 1 to 9.
