压力钢管运行安全监测系统初步设计

水电厂压力钢管运行安全的问题不可忽视。针对目前压力钢管安全监测系统技术不够完善的情况,设计了一种全新的压力钢管实时安全监测系统。分析了当前压力钢管安全监测现状及其存在的问题,明确压力钢管监测系统的设计原则。提出了基于有线局域网和基于无线网络所构建的2种监测系统结构,并图示其相应系统的组成。从系统的工作原理、功能模块、程序设计方案等方面予以分析,详细介绍了测点布置的选取方法,对压力钢管与伸缩节之间振动响应的传递函数关系作了简要分析,为水电厂压力钢管安全监测工作提供参考。

Preliminary Design of a Monitoring System for the Safe Operation of Hydro-plant Penstocks

The safe operation of penstocks in hydro-plant is unneglectable. A monitoring system for the safe opera-tion of hydro-plant penstocks is designed in this research based on analyzing the present situation and problems in the monitoring of penstocks safe operation and clarifying the design principles. Two monitoring system structures based on wired LAN (local area network) and wireless network are proposed, and the compositions are shown by diagrams. The system is described in aspects of working principles, functional modules, program design and etc., and in particular, the test point arrangement is expounded. The function relationship for the vibration response transfer between penstocks and expansion joint is also briefly analyzed. The system offers a reference for the safety monitoring of penstocks in hydro-plant.
