信息物理系统(CPS)在工业控制、智能交通、远程医疗等领域取得了长足的进步。煤矿运输控制系统是CPS中具有代表性的多子系统。在本研究中,为了优化事件响应的调度机制和精确控制系统中有轨电车的行为,我们提出了一种基于无记忆连续时间模型的面向事件调度算法(EOSA)来实现快速响应。因此,控制系统可以根据实时负载情况匹配队列中的任务,并且每个物理实体可以在离散事件环境下准确执行指令。仿真结果表明,与混合遗传算法和模糊聚类调度算法相比,该算法具有更高的执行速度。该方法实现了全局任务调度的负载均衡,更适用于矿山运输场景。
Cyber-physical systems (CPS) have made great strides in industrial control, intelligent transportation, remote medical and other fields. Coal mine transportation control system is a representative multi-subsystem of CPS. In this study, for the sake of optimising the scheduling mechanism for event response and precise control of tramcar behaviour in the system, we propose an event-orient scheduling algorithm (EOSA) to achieve a rapid response based on building a no-memory continuous time model. Therefore, the control system can match tasks in the queue according to the real-time load situation, and each physical entity can accurately execute the instruction under discrete event environment. Simulation results have shown that the proposed algorithm has a higher execution speed compared with the hybrid genetic algorithm and fuzzy clustering scheduling algorithm. Our approach realises the load balancing of global task scheduling and is more suitable for mine transportation scenario.
