Virtual microwave technology experiment system

Abstract

An experiment system of virtual microwave technique is prepared as finalizing local area network-setting by connecting 30-40 sets of computers through exchange board and network, selecting one set of computer from them as server, erecting server version software of said system on selected computer and finalizing databank-setting on it, erecting client version software on all computers and finalizing client network end-setting on them, connecting said server to said client computers through exchange board and realizing call control between server software system and client software system through Guest account number of Windows operation system.

Description

technical field [0001] The invention belongs to the field of microwave technology. Background technique [0002] With the rapid development of economy and science and technology, my country's higher education has entered a period of rapid development. But at the same time, due to the expansion of enrollment in colleges and universities in recent years and the improvement of national teaching quality requirements, many colleges and universities are facing relatively tight teaching funds and a serious shortage of high-end equipment for experimental teaching. Experimental teaching plays a vital role in higher education. Therefore, experimental teaching is an important reason for the low quality of higher education. [0003] "Microwave Technology" is an important basic course for information majors, and its experimental link plays a vital role in the understanding and mastery of this course. In recent years, information majors have been very popular. There are hundreds of sch...

Problems solved by technology

[0004] 1. The price of microwave devices is very expensive: a typical set of microwave experimental equipment, including microwave signal sources, frequency-selective amplifiers, measuring lines, and small power meters, costs about 30,000 yuan. , at least 30 sets of instruments are needed, that is to say, to set up a microwave laboratory, the investment in the experimental instruments alone needs to be nearly 1 million, which is unaffordable for most colleges and universities;

[0005] 2. Microwave experimental instruments are easily damaged and difficult to maintain: microwave experimental instruments work at higher frequencies, and the operating frequency can reach 10 GHz. During the process, the frequency of damage or abnormal operation of experimental instruments is relatively high, and domestic manufacturers of microwave instruments are limited in scale, and timely maintenance of instruments cannot be obtained in most areas;

[0007] 4. In recent years, wireless communication technology has developed extremely rapidly, and the mainstream technology and equipment are updated quickly. In order to keep up with the mainstream technology and ensure the quality of teaching, some expensive experimental equipment such as network analyzers may replace the existing microwave experimental equipment in a few years. , this is also a problem that has to be considered for colleges and universities that plan to purchase microwave experiment equipment in recent years;

[0008] In addition, even in schools that offer microwave experiments, the number of experimental instruments is seriously insufficient relative to the number of experimenters, which will inevitably affect the quality of experimental teaching
