The invention relates to the technical field of production control, in particular to a mining instrument production line control system and method based on adaptive scheduling and multi-protocol fusion, and the method executed by the system comprises the steps: 1, triggering a production task according to an order; 2, analyzing a production task, disassembling the production task into a plurality of sub-tasks, distributing the sub-tasks to different stations to implement production, and monitoring the state of each station in real time; wherein in the production process, the production mode is adjusted in real time according to the order priority and the production state of each station. Through the adaptive task scheduling engine, the system can dynamically optimize the task allocation and execution sequence according to the real-time production state, and effectively cope with disturbances such as emergency order insertion and equipment faults.
