[0002] Rail transfer vehicles are automated transport equipment that runs on dedicated tracks. They are usually used for automated transport of materials or goods in industrial, warehousing and logistics, mining and other scenarios. Their design draws on the railway transportation system and uses track guidance to move automatically or semi-automatically within a predetermined route. Rail transfer vehicles can carry out precise transportation according to the preset tracks without the need for human intervention, and can efficiently complete the task of transporting materials, goods or products.

[0003] At present, although the existing route planning of rail transfer vehicles can handle routine transportation tasks, when faced with multiple tasks, multiple transfer vehicles, and multiple priorities, the route planning has problems such as inefficiency and unreasonable planning, resulting in reduced transfer efficiency; when faced with failures of rail transfer vehicles, there is a problem that they cannot be handled in a timely and effective manner.

[0004] In order to solve the above-mentioned defects, an intelligent transfer control system for a rail transfer vehicle is now provided. Summary of the invention

[0047] Get the current power of the rail transfer vehicle and mark it as Ei, where i = 1, 2, 3...I, I is a positive integer, I represents the total number of rail transfer vehicles, and i represents the number of any rail transfer vehicle; get the maximum power of the transfer vehicle (power when fully charged) and mark it as Emax; get the fault signal on the rail transfer vehicle and mark it as Fi, where When Fi = 0, it means that the transfer vehicle has a fault or is at risk of failure, and the rail transfer vehicle is marked as a maintenance transfer vehicle and does not participate in task allocation; obtain the load capacity of the rail transfer vehicle and mark it as Wi; substitute the current power Ei of the fault-free rail transfer vehicle, the maximum power Emax of the transfer vehicle, and the load capacity Wi into the set formula The carrying value Zi of the rail transfer vehicle is calculated, where a1 and a2 are the set weight factors respectively. It can be seen from the formula that the greater the current power of the vehicle, the greater the carrying value of the rail transfer vehicle; the greater the load capacity of the vehicle, the greater the carrying value of the rail transfer vehicle;

[0048] A carrying threshold is set, and the carrying value of the rail transfer vehicle is compared with the set carrying threshold for analysis; when the carrying value of the rail transfer vehicle is greater than the set carrying threshold, the rail transfer vehicle is marked as a rail transfer vehicle to be transferred, and the vehicle to be transferred will be used for task allocation, and the number of all rail transfer vehicles to be transferred will be counted; when the carrying value of the rail transfer vehicle is less than or equal to the set carrying threshold, the rail transfer vehicle is marked as a rail transfer vehicle to be maintained, and the vehicle to be maintained should be charged or troubleshooted until the carrying value threshold is reached before it can re-participate in the task, and the number of all rail transfer vehicles to be maintained will be counted;

Only vehicles suitable for the task are assigned to the transfer task, ensuring the rationality of task allocation and improving resource utilization. Path calculation can effectively reduce the travel time of the transfer vehicle, reduce energy consumption, and improve the efficiency of task completion. By comprehensively considering multiple factors such as vehicle power, load, fault status, task priority and path planning, flexible task scheduling, dynamic path adjustment, and timely adjustment in the event of an emergency can be achieved to ensure efficient operation of the system and optimal utilization of resources.
