摘要
针对空气预热器移动式热点检测系统机构易"卡死"、热点检测严重滞后等问题,利用红外阵列传感器具有较宽测量范围的特点,提出一种固定式基于红外阵列传感器的热点检测方案。为满足红外阵列传感器Modbus通讯的需要,将电气装置设计为Modbus总线式结构。针对红外阵列传感器特点,提出了基于Dempster-Shafer(DS)证据理论的热点检测方法,该方法具有较高的检测精度。本方案与移动式检测方案相比较,在工作可靠性、热点检测精度等方面都有所提高。
With the aim of such problems as the ＂clogging＂ and serious delay of hot detection easily occurred in the mobile hot spot detection system mechanism of air preheater,a fixed hot spot detection system based on an infrared array sensor with a wide measuring range is proposed in this paper.In order to meet the need of infrared array sensor communication based on Modbus protocol,electric apparatus is designed to Modbus bus-type structure.With the aim of the infrared array sensor features,a hot spot detection method based on Dempster-Shafer（DS） evidence theory is proposed in this paper.This method has higher detection accuracy.Compared with the mobile detection system,the system reliability and detection accuracy have been improved.
