【摘要】 磁带法测量雷电流参数,在国内外均有研究。实践证明,该法是一种测量雷电流参数的好方法,具有测量精度高、抗干扰能力强、运行成本低的特点。但目前的研究,更多的只是用磁卡在采集点上采集雷电信号,然后取下用录音机或磁卡机来读取,没有实现自动采集与实时处理。本课题的提出,是基于磁带测量雷电流参数的可行性及存在问题,采用单片机控制技术、GPRS(General Packet Radio Service,通用分组无线业务)通信技术来实现雷电流参数的自动采集与远程传输。论文主要研究内容有:1.雷电流参数的采集。应用磁带记录技术、单片机控制技术对雷电流参数进行实时采集。2.雷电流参数的远程传输。主要依赖于GPRS通信网络与Internet通信网络。GPRS是在现有GSM系统上发展起来的一种新的承载业务,对原有GSM设备无需进行大的改动。由于GSM网络已经成熟,覆盖面又广,利用GPRS无线通信方式来实现雷电参数的采集与传输,是对现有资源的最大利用。3.数据监控中心软件的设计。采用功能强大的Visual C++,并利用TCP/IP编程接口WinSock来编写。完成对采集模块传送来的信息进行处理,得出雷电流的幅值、陡度等,对雷电的反击、绕击进行判别。4.设备的防护及供电。该系统能对大范围、区域性的雷电流参数进行测量,为雷电普查、雷击点准确定位、雷击事故分析提供依据;能够准确掌握雷电活动规律,对雷害实施有效的监测和预警,便于各单位有针对性地采取措施,减少雷害的发生。更多还原

【Abstract】 There are some researches on measuring lightning current parameters which based on magnetic tape record method at home and abroad. The practice prove that it is a good way to measure lightning current parameters, which has the virtue of high measurement accuracy, good antijamming ability, and low running cost. In recent research, people often focus on the method that use magnetic tape to gather lightning signal on the gather point, then read out the information from the tape reader, which can’t implement automatic gathering and Real-time Date Acquisition.Based on the feasibility of measuring lightning current parameters by magnetic type and the problems to be solved, the subject is put forward to implement automatic gathering and remote transmission by using technique of single chip microprocessor and GPRS (General Packer Radio Service).The Mainly study on the subject is listed below.1. Acquisition of lightning current parameters. The objective is applying magnetic tape record technique and single chip microprocessor technique to implement Real-time Data Acquisition of lightning current parameters.2. Remote Transmission of Lightning Current Parameters. It mainly relies on GPRS communication network and Internet communication network.GPRS is a new bearer service that developed from the GSM system, and it doesn’t need to excessively modify the GSM device. For GSM network communication technique is perfect and has large-scale covering area, we can take the advantage of GPRS remote communication to implement Real-time acquisition and transmission of lightning current parameters. That will make best use of our current resources.3. Design of the data monitor center. We can adopt the powerful Visual C++, and take the advantage of its special TCP/IP programmable interface WinSock to design the data monitor center. The data monitor center will analyze the data transmitted from acquisition module, and work out the parameters such as lightning peak current, lightning steepness, then judge the lightning back flashover and shielding failure.4. Protection and power supply of the device.The system can process long-range and regional acquisition of the lightning current parameters, which give support to the census of lightning, accurately locating the lightning strike point, and lightning strike accident analysis. What’s more, it can accurately figure out the regular pattern of the lightning, and effectively monitor and early warn the lightning, then helps every unit take action to reduce the possibility of lightning damage.更多还原
