网架干煤棚安全监测系统的设计与开发

The design and development of the security monitoring system for grid structural coal-shed

针对目前火电厂网架干煤棚安全监测手段空白的现状 ,提出了开发干煤棚安全监测系统的方案 ,并开发了原形系统 .系统采用高精度、大量程、抗恶劣工作环境的振弦传感器监测网架特征节点的空间位移 ,通过对各个特征点绝对位移量的监测以及节点之间相对位移量的报警模式来判断网架的状态 。

An idea of developing the security monitoring system for coal-shed was put forward and carried out. In this system the displacements of the key nodes were measured by vibrating wire sensors with high accuracy, wide range and adverse environment resistant. Through monitoring the nodes′ absolute displacements and the alarm mode of relative displacements the state of the coal-shed and the proper maintaining proposition could be estimated.
