摘　　要：针对多机装备可视化监测中存在的数据体量大以及单台主机模式下无法有效完成复杂任务的问题,提出了基于实时运行数据驱动的分布式液压支架群虚拟监测方法.该方法首先建立了基于实时运行数据的驱动模型;其次基于可识别数据交互器的数据传递方法,建立了C/S模式下的分布式局域网协同模型;然后基于一致性哈希算法的分配方法,建立了可根据主机负载状况动态分配任务的任务调度模型,最后以试验室液压支架群为例构建了分布式系统.试验结果表明:该方法建立的监测系统相比于单主机系统,提高了监测的稳定性,能够为透明综采工作面的建设提供核心技术支撑.To solve the problems of data quantity in visual monitoring for multi-machine equipment and some irresolvable complex tasks in single host model,a virtual monitoring method driven by real-time running data was proposed for a distributed hydraulic support group.Firstly,a driving model was established based on real-time running data.According to a data transfer method of identifiable data interactors,a distributed local area network collaboration model was established under C/S mode.And then,based on an allocation method of monitoring tasks with consistent Hash algorithm,a task scheduling model was established to dynamically allocate tasks according to the host load status.Finally,taking the laboratory hydraulic support group as the experimental object,a distributed virtual monitoring system was constructed.The experimental results show that,compared with the system established with a single host,the monitoring system established by this method can greatly improve the stability of monitoring and can provide core technical support for the construction of transparent fully mechanized mining face.
