应用马尔文激光粒度仪分析泥沙数据处理模板

Abstract

马尔文激光粒度分布仪始于本世纪初应用于河流泥沙粒度分析，虽然与传统的沉降法分析原理有着本质的区别，但其仪器所具备的操作简便、分析数据稳定和处理自动化程度高、成果获取快等优点，深受使用者的青睐，目前已在河流泥沙颗粒分析中得到了应用和普及。然而，用户在仪器使用中会遇到一些具体问题：如基础参数设定和检查不方便、测试数据的好坏无法自动检测和提示处理，测试的颗粒级配数据特征值及极值挑选比较麻烦、分析报告格式不统一、数据读取和输出处理繁琐等。为解决这些问题，并统一各泥沙监测站的激光仪操作方法和要求，在充分利用激光仪现有功能的基础上，开发研制出了一套“马尔文激光粒度仪泥沙数据处理模板”，该模板能自动配置基础参数、对分析数据进行质量检查并提示，按测站编码打印标准格式报告单、形成批量分析数据的文本输出文件等，可直接提供给南方片的整汇编软件进行整理、整编等。经过近几年的运行取得良好效果，提高了工作效率，减少了出错机率，保障了成果质量。 Malvern laser particle size analyzer has been applied in the particle analysis of river sediments since the beginning of this century, and has been highly praised by users for simple operation, stable data from analysis, high automation of processing and quick achievements, etc. regardless of its significant deviation from the principles of traditional sedimentation analysis approach. Now, it has been applied and popularized in the particle analysis of river sediments. Nevertheless, users may run into some problems in the use of this equipment, such as, inconvenient setting and check of fundamental parameters, lack of automatic detection and warning about quality of test data, troublesome selection of characteristic and extreme values in the data of tested particle grading, inconsistent form of analysis report, and cumber-some reading and output of data, etc. To solve these problems and unify the principles and requirements for operation of laser analyzer at the sediment monitoring stations, a “sediment data processing template for Malvern laser particle size analyzer” is developed while making full use of the existing functions of laser analyzer. This template is able to configure the fundamental parameters automatically, check the quality of analytic data and give warnings, print the reports in standard form according to the code of each monitoring station, and generate the textual output of analytic data in batches, etc., which can be directly sorted out and edited in the Southern Hydrological Data Processing (SHDP) software. The operation for several years has achieved favorable effects, improved working efficiency, reduced error rate and ensured the quality of achievements.
