大型排水暗涵清淤作业智慧管控系统研发与应用

Development and Application of Intelligent Control System for Large Drainage Culvert Based on Internet of Things

为解决大型排水暗涵清淤作业安全风险高、作业人员伤亡多等问题,在暗涵清淤过程中,通过研究有毒易燃易爆气体释放机理、封堵失效规律、人员管控要点及应急救援需求,构建了基于“感知层-传输层-处理层-应用层”的大型排水暗涵清淤安全管控通用化系统,包括分级通风、水位响应、人员管控、覆盖监控及辅助施救等功能模块,在2020年8月应用于黄孝河机场河流域综合治理一期项目,实现了29.4 km大型排水暗涵清淤超危作业零伤亡目标,切实有效降低了大型排水暗涵清淤作业安全风险。

In order to solve the problems of high safety risk and many casualties in the dredging operation of large drainage culvert,a general safety control system for dredging of large-scale drainage culvert based on the architecture of perception layer,transmission layer,processing layer and application layer is constructed through the research on the release mechanism of toxic,flammable and explosive gases,the rule of blocking failure,the key points of personnel control and the requirements of emergency rescue.The system includes functional modules such as hierarchical ventilation,water level response,personnel control,coverage monitoring and auxiliary rescue.It was applied in the phaseⅠcomprehensive management project of Huangxiao-Jichang River basin in August 2020,achieving the goal of zero casualties in dangerously dredging 29.4 km of large-scale drainage culvert,and effectively reducing the safety risk of dredging operation of large-scale drainage culvert.
