火焰探测器中虚警和慢响应的问题解决
Solution of false alarm and slow response in flame detector
摘要
Abstract
A new flame detector with one ultraviolet and two infrared detectors is designed.The ultraviolet detector is of rapid response (≤ 10 μs) while the two infrared detectors usually have a response time of more than 5 ms.The ultraviolet detector is applied to deal with the flame of large scales.When facing the flame of mid or small scales,the three detectors cooperate.Employing the high-order derivatives of the sample data of the infrared circuits to improve the sensitivity,the response speed is greatly improved.The data of the temperature sensor is used to adjust circuit parameters in real time,thus reducing the effect of temperature drift.The flame detectors are tested at different distances and the response time is as rapid as 0.65 ms.The test results show that the new flame detector has the characteristics of high speed and a low rate of false alarms.关键词
