The Collection Query System Of Shanxi Province Lightning Information

Lightning is a long-distance electrostatic discharge phenomenon in the atmosphere.It is a natural disaster which may bring catastrophic damage to buildings or equipment.Recent years, with rapid socio-economic developments and deepening of themodernization, especially the popularization of microelectronic technology in manyfields, it is easier that the lightning will cause severer damage. Therefore, lightningprevention job, benefited the people’s livelihood greatly, have been orderly conductedall over the country and witnessed remarkable achievements. However, in the lightningprevention job, people are always emphasizing more on routine testing of buildings,drawing inspection of newly-built buildings while ignoring collecting and compiling oflightning data. At present, although Shanxi Province did some studies and researches onlightning disaster, there are still a bunch of information of lightning disaster should befurther collected. What’s more, the lack of systematical collating of lightning disasterdata makes the lightning prevention job even harder. Thus, it is the critical time forShanxi Province to establish a complete set of lightning data collection and inquirysystem, which is of great importance to the study of mechanism as well as distributionfeatures of lightning disaster.The lightning information database of Shanxi Province, used Microsoft SQLServer2000, has been designed on the basis of collating and analyzing lightningdisaster data of cities and counties in Shanxi Province (2000-2011), thunderstorm daydata of cities and counties in Shanxi Province(2000-2011), lightning location data ofShanxi Province (2006-2011) and local atmospheric electric field data (2008-2011).Based on the lightning information database, the lightning data collection andinquiry system of Shanxi Province has been designed and developed by means of usingC++as development languages and VisalStudio6.0as development environment. Theuse of the system will promote the unified management and orderly utilization ofrelevant data of lightning disaster, lightning location, atmospheric electric field,thunderstorm day. When users require some relevant data, they just need to open thecorresponding subsystem and click on specific options, then the data and the results will show on the screen. This system will be a sound support to the scientific research oflightning meteorology in the future.The thesis illustrates the necessary of establishing lightning data collection andinquiry system of Shanxi Province, disserts all the technical means and the key pointsrequired by the system, introduces the system structure and features of each subsystem,and conducts a detailed tests of system application in the end. Besides, the thesis alsodescribes the source of collecting all the data concerning lightning disasters, lightninglocation, atmospheric electric field and thunderstorm day.
