【摘要】：随着我国经济和技术的高速发展,雷电灾害造成的雷击危害也在增加。特别是高新技术的发展,计算机等电子产品的广泛应用,雷电灾害被列为了一大电子公害。雷电是自然界每年都发生的自然现象,自从美国科学家富兰克林研究雷电现象到现在,人们已经基本掌握了雷电的规律。为了减少雷击对建筑物、人身和财产所造成的伤亡损失。国际标准化组织分别制定了各种建筑物防雷设计规范及雷击风险评估标准。在我国的建筑物避雷设施设计中,必须遵照国家标准GB50057-2010《建筑物防雷设计规范》,目的是防止雷击侵入,减少人身伤亡和财产损失。本文主要研究雷电流累积率与雷击概率,采用的标准是《IEC62305》雷电防护标准。主要研究内容包括:1、分析雷闪数据的格式,基于《IEC62305》研究总结了雷电流累积率、平均密度和雷击概率的计算方法。2、系统采用B/S模式,Apache+MYSQL+PHP技术,开发出的雷电流累积率与雷击概率统计系统。3、全文对系统的设计与实现进行了比较详细的论述,雷电流累积率与雷击概率的计算,特别是识别数据是否在区域内的方法进行了详细的分析设计。采用计算经纬度两点之间距离的方法。实践证明,这种方法简单、准确。4、对雷闪数据的转换、管理和备份等功能,进行了模块设计。雷电流累积率与雷击概率统计通过实践运行,在防雷趋化分析中,证明了设计的可行性和准确性,基本实现了需求分析中的功能要求。
[Abstract]:With the rapid development of economy and technology in China, the lightning damage caused by lightning disaster is increasing. Especially with the development of high and new technology and the wide application of computer and other electronic products, lightning disaster is listed as an electronic hazard. Lightning is a natural phenomenon occurring in nature every year. Since Franklin studied the phenomenon of lightning, people have basically mastered the law of lightning. In order to reduce lightning damage to buildings, people and property caused by casualties. The International Organization for Standardization (ISO) has formulated various building lightning protection design codes and lightning risk assessment standards. In the design of lightning protection facilities of buildings in our country, we must abide by the National Standard GB50057-2010 "Design Code for Lightning Protection of buildings", in order to prevent lightning attack and reduce personal casualties and property losses. This paper mainly studies the lightning current accumulation rate and lightning strike probability. The standard adopted is < IEC62305 > Lightning Protection Standard. The main research contents include: 1, analyzing the format of lightning flashover data, summarizing the calculation method of lightning current accumulation rate, average density and lightning strike probability based on < IEC62305 >. The system adopts B / S mode Apache MySQL PHP technology. The lightning current accumulation rate and lightning strike probability statistical system. 3. The design and implementation of the system are discussed in detail, and the calculation of lightning current accumulation rate and lightning strike probability is discussed in detail. In particular, the method of identifying whether the data is in the region is analyzed and designed in detail. The method of calculating the distance between latitude and longitude is used. It is proved that this method is simple and accurate. The functions of lightning flashover data conversion, management and backup are designed. The lightning current accumulation rate and lightning strike probability statistics are operated through practice. The feasibility and accuracy of the design are proved in the lightning chemotaxis analysis, and the functional requirements in the requirement analysis are basically realized.
