摘要
介绍了红外辐射标定方法,分别用近距离直接扩展源法、远距离小源法对红外告警设备开展外场标定,并进行了验证及误差分析。结果表明,在10℃~50℃温度范围,近距离直接扩展源法的相对标定误差在5.67%~15.73%之间;远距离小源法在37 m处的相对标定误差在1.38%~5.72%之间,在63 m处的相对标定误差在10.34%~29.66%之间,说明对于采取周扫方式工作的红外告警设备,在适当的距离处,远距离小源法是外场标定的有效方法。
The infrared radiation calibration method was introduced,the field calibration of infrared warning equipment was carried out by short-range direct extended source method and long-distance small source method,and the verification and error analysis were carried out.The results show that the relative calibration errors of the short-range direct extended source method is between 5.67%to 15.73%at the temperature range of 10℃~50℃.The relative calibration errors of the long-distance small source method at 37 m ranging from 1.38%to 5.72%,and those at 63 m ranging from 10.34%to 29.66%,indicating that the long-distance small source method at an appropriate distance is an effective method for field calibration of infrared warning equipment operating in the mode of circular scanning.
