Abstract


With the continuous development of science and technology , has become a hot spot of the world space exploration of deep space exploration . Mars as our neighbors , many of its features are similar and we survive Earth there are too many mysteries plaguing us . In order to better explore Mars , we must understand the Martian space environment , China 's National Space Administration Mars exploration reached a cooperation plan between the Russian Federal Space Agency - China - Russia joint Mars exploration program , China is responsible for the development of YH-1 Mars exploration satellites around Mars probe the Martian space environment . As part of the YH-1 Mars exploration satellite , YH-1 plasma probe packets is mainly used for the detection of ion escape rate study physical processes escape and transport mechanisms , and explore the ways and mechanisms of Martian water loss . First, research the space plasma environment of Mars and its detection technology . Describes the design principles of the YH-1 plasma probe packets , structure and composition . The the ion analyzer I ion analyzer , electronic analyzer performance indicators . In the development process of the detector , ground testing equipment plays a very important role . This paper introduces the design I have developed a ground- testing equipment and various parts of the works . Comprehensive introduction to the two parts of the ground inspection equipment USB2.0 interface system and data acquisition system , and specifically discusses the USB2.0 interface, the basic knowledge of the system , the hardware circuit design , driver design , firmware design and application software design . Also described in detail the design of the data acquisition system based on FPGA logic circuit design and peripheral hardware circuit . Finally, the entire ground testing equipment designed to process and test results .
