空气质量.雪深传感器的试验方法

[中文适用范围]： 本文件规定了雪深传感器测试方法的评估和使用要求。 本文件适用于以下类型的自动雪深传感器，这些传感器采用不同的测距技术来测量雪面到传感器的距离： a) 超声波型，也称为声波测距深度传感器； b) 光学激光雪深传感器，包括单点和多点雪深传感器； c) 其他雪深传感器。 本文件主要涵盖两大测试：实验室（室内）测试和现场（室外）测试。 实验室测试包括基本性能测试和各种环境变化下的其他测试。 建议进行现场测试，以确保雪深传感器在现场测量条件下的性能。 对于现场测试，本文件中定义的程序考虑了自然地面和人造目标表面（例如雪板）。 [外文原描述]： This document provides requirements for the evaluation and use of test method for snow depth sensors. This document is applicable to the following types of automatic snow depth sensors which employ different ranging technologies by which the sensors measure the distance from the snow surface to the sensor: a) Ultrasonic type, also known as sonic ranging depth sensors; b) Optical laser snow depth sensors including single point and multipoint snow depth sensors; c) Other snow depth sensors. This document mainly covers two major tests: a laboratory(indoor) test and a field (outdoor) test. The laboratory test includes the basic performance test and other tests under various environmental changes. The field test is proposed to ensure the performance of the snow depth sensors in field measurement conditions. For the field test, both the natural ground and artificial target surface such as snow plates are considered for the procedures defined in this document.
