28孔弧型闸门担负着大黑汀水库工程挡水泄洪的繁重任务，其控制系统更是这重中之重。平时工程管理中仅维持单孔就地启闭操作管理运行，倘若需要大流量泄洪，则需要多增加运行人员，这种仍停留在较低管理水平上管理方式，不能满足现代化管理的需要。自1986年工程正式移交管理单 The 28-hole arc gate is responsible for the heavy task of retaining and releasing floods in Daheiting reservoir project. Its control system is even more important. In normal project management, only single-hole opening and closing operation and management operation are maintained. If large flow discharge is needed, additional operation personnel are required. This management mode still remains at a lower management level and can not meet the needs of modern management. Since 1986 the project formally transferred to the management list
