摘要降雪是大自然最常见的气象之一,也是最难以测量的。降雪不断堆积,以及消融后结冰,会造成极大的安全隐患,对高速铁路行驶安全带来威胁。
本文首先介绍了超声波及激光测量雪深的基本原理,并对市场上常用的超声波雪深传感器和激光雪深传感器参数进行分析比较。在明确雪深监测需求后,选择以激光雪深传感器为中心构建一套雪深实时监测系统。硬件方面,完成了满足精度要求的传感器及摄像头等硬件设备的选型,确定需要输出的信号个数及接口方式。软件方面,设计出基于组态王,并与硬件平台相适应的PC控制系统,实现雪深和视频信号的接入,历史数据的调用,预警信息提示等功能。20903

Title The design and test of the high-speed rail snow depth monitoring system
Abstract
Snowfall is one of the most common weather of the nature, and is the most difficult to be measured. Snowfall’s accumulation and freeze cause great security risk, threat high-speed railway traffic’s safety.
This paper first introduces the basic principle of ultrasonic and laser measurement of snow depth, and the parameters of ultrasonic snow depth sensors and laser snow sensors often seen on the market were analyzed and compared. After clearing Snow depth monitoring requirements, laser snow depth sensor is chosen as the heart to build a system of real- time monitoring of railway snow depth. In terms of hardware, I completed the selection of sensors and cameras and other hardware equipment which meet the requirement of accuracy, and determined the number of output signal and interface mode .And on the other hand, in terms of the software, I designed the PC control system based on Kingview and adapted to the hardware platform, realizing the access of snow depth and video signal, historical data, warning message and so on.
