Description
Multi-mode port logistics self-adaptive scheduling system and method Technical Field The invention relates to the field of port logistics scheduling and artificial intelligence application, in particular to a multi-mode port logistics self-adaptive scheduling system and method, which aim to solve the problems of complex port collection and distribution scheduling, serious information island, difficult resource coordination and the like and realize intelligent, efficient and low-carbonization scheduling of port operation. Background With the continued expansion of global trade size, ports are increasingly important as international logistics hubs. The modern port relates to a plurality of operation links such as shore bridge loading and unloading, storage yard management, integrated card dispatching, molten iron intermodal transportation and the like, and the types of data generated by each link are various, including video monitoring, AIS ship track, ioT sensor data, voice intercom, text dispatching instructions and the like. However, the existing port scheduling system has the following technical problems: The information island is serious, the data formats among different systems (TOS wharf operating system, GOS gate system and equipment monitoring system) are not uniform, and cross-system data fusion and collaborative decision-making are difficult to realize. Video, sensor and text data of each operation link are stored in a scattered manner, and a unified space-time alignment mechanism is lacked. The traditional scheduling method mainly depends on manual experience and static rules, and cannot respond to dynamic changes such as storage yard congestion, equipment failure, weather mutation and the like in real time. The scheduling instruction has a long generation period, and is difficult to adapt to the high-frequency ship arrival and cargo circulation requirements. The resource coupling relation is complex, namely, a strong coupling relation exists among the resources such as a shore bridge, a field bridge, a collector card, a pile position and the like, and the scheduling change of a single resource can cause a chain reaction. The existing system lacks global modeling capability for resource coupling relation, which results in the problem of local optimization but global suboptimal. The abnormal recognition capability is insufficient, various abnormal conditions such as empty box accumulation, dangerous goods dislocation, channel congestion and the like exist in port operation, the existing system mainly depends on manual inspection, the recognition efficiency is low, the response speed is low, and potential safety hazards exist. And the energy consumption and the carbon management are lost, and in the background of a double-carbon target, the port scheduling needs to be compatible with the optimization of the operation efficiency and the energy consumption. The existing dispatching system mostly takes the shortest operation time as a single target, and does not incorporate indexes such as energy consumption, carbon emission and the like into a dispatching decision system. In the prior art, some ports are scheduled by adopting a rule-based expert system or a single optimization algorithm (such as a genetic algorithm and a particle swarm algorithm), but the methods have the following limitations: 1. the rule system is difficult to cover complex and changeable harbor scenes, and the generalization capability is poor; 2. the single optimization algorithm is difficult to process the multi-mode data fusion problem; 3. Lack of learning and multiplexing mechanisms for history scheduling experience; 4. Natural language generation and voice interaction of scheduling instructions cannot be achieved. Therefore, an intelligent scheduling system which can integrate multi-mode data, sense port situation in real time, adaptively generate scheduling decisions and support man-machine cooperation is urgently needed, so that port operation efficiency is improved, energy consumption is reduced, and safety is guaranteed. Disclosure of Invention In order to solve the problems, the invention provides a multi-mode port logistics self-adaptive scheduling system and a multi-mode port logistics self-adaptive scheduling method, which are used for realizing port operation self-adaptive scheduling by constructing a port space-time semantic model, fusing multi-source heterogeneous data, analyzing real-time situation and generating intelligent decisions. The system is accessed into multi-mode data sources such as a quay bridge operation video, an AIS track, an unmanned plane yard top view, an equipment (IoT) sensor, intercom voice, a ship company manifest, a railway/highway dispatching text, meteorological/tidal data and the like, and the heterogeneous data is mapped to a unified space-time semantic space through a multi-mode alignment mechanism driven by a port business body.
