【摘要】：隨著現(xiàn)代科技的快速進(jìn)步,生活中的各種電子產(chǎn)品的使用越發(fā)普及,這些電子設(shè)備在方便我們工作生活的同時(shí),也帶來(lái)了不可忽視的電磁輻射。研究表明,當(dāng)電磁輻射強(qiáng)度達(dá)到一定程度時(shí)會(huì)對(duì)人類的健康造成影響。因此,避免電磁輻射的危害也逐漸引起了人們的關(guān)注。本文在對(duì)輻射測(cè)量的基本原理和方法研究的前提下,討論了一種設(shè)計(jì)便攜式的輻射測(cè)量計(jì)的方案。該方案將輻射測(cè)量系統(tǒng)劃分為三個(gè)模塊:天線探頭、頻率估計(jì)模塊以及后端信息處理模塊。天線探頭作為檢測(cè)信號(hào)的輸入端,接收信號(hào)的輸入功率。頻率估計(jì)模塊主要功能為區(qū)分輸入信號(hào)頻率和檢測(cè)天線接收的功率。后端信息處理模塊將采集到的信息傳輸?shù)街悄芙K端上進(jìn)行分析和計(jì)算。天線探頭部分采用了本文基于傳統(tǒng)對(duì)拓Vivaldi天線改進(jìn)的小型化超寬帶天線,為了解決后期測(cè)量中對(duì)天線特性的補(bǔ)償,提出了頻率估計(jì)的理論設(shè)想。在對(duì)輻射測(cè)量計(jì)前端信號(hào)檢測(cè)模塊的設(shè)計(jì)與仿真的基礎(chǔ)上,加工了超寬帶天線和頻率估計(jì)模塊。在實(shí)際測(cè)試結(jié)果表明,改進(jìn)的超寬帶天線能夠滿足輻射測(cè)量計(jì)對(duì)信號(hào)檢測(cè)的要求,另外,通過(guò)對(duì)頻率估計(jì)模塊的測(cè)試和數(shù)據(jù)分析,表明了該頻率估計(jì)理論設(shè)想的可行性。在整合了A/D轉(zhuǎn)化電路、串口/USB電路作為輻射測(cè)量計(jì)后端信息處理模塊。給出了便攜式輻射計(jì)在測(cè)量過(guò)程中的具體過(guò)程。
[Abstract]:With the rapid progress of modern science and technology, the use of various electronic products in life is becoming more and more popular. These electronic devices not only facilitate our work and life, but also bring electromagnetic radiation that can not be ignored. Studies have shown that when the electromagnetic radiation intensity reaches a certain level, it will have an impact on human health. Therefore, to avoid the harm of electromagnetic radiation has gradually attracted people's attention. Based on the research of the basic principle and method of radiation measurement, a scheme of designing portable radiometer is discussed in this paper. The radiation measurement system is divided into three modules: antenna probe, frequency estimation module and back-end information processing module. The antenna probe acts as the input of the detection signal and receives the input power of the signal. The main function of the frequency estimation module is to distinguish the input signal frequency from the power received by the antenna. The back-end information processing module transmits the collected information to the intelligent terminal for analysis and calculation. In the part of antenna probe, the miniaturized ultra-wideband antenna based on the traditional Vivaldi antenna is used in this paper. In order to compensate the antenna characteristics in the later measurement, a theoretical assumption of frequency estimation is put forward. Based on the design and simulation of the front-end signal detection module of radiometer, the ultra-wideband antenna and frequency estimation module are fabricated. The experimental results show that the improved UWB antenna can meet the signal detection requirements of the radiometer. In addition, the feasibility of the proposed frequency estimation theory is demonstrated by testing the frequency estimation module and analyzing the data. In the integration of the A / D conversion circuit, serial port / USB circuit as a radiometer back-end information processing module. The specific process of portable radiometer in the measurement process is given.
