The Research Of Flight Temperature Test System

Temperature is a important parameter of many monitoring systems, it is very significant to the related technologies of flight and therefore the research of the flight temperature is necessary.The subject of this project is is to research and realize a flight temperature system applied to a temperature tester with miniaturization,mass capacity,nonvolatility and low power dissipation, the system structure can be standardized and modularized. The development trend of the temperature test and memory test technology at home and abroad is analyzed first; Secondly the process of hardware and software design and debugging are introduced;Then discusses the method of thermocouple calibration and introduces testing data;Finally,the scheme to be improved and innovated is discussed.Kinds of key technology are involved in the project.The system uses a uniform sampling strategy to achieve the uniformity sampling of the temperature signal;In the order to distinguish the data channaland dislocation in the transmission,the system codes the data;In the data transmission,the system transfers the time-sharing data inorder to ensure the accuracy of data;When storing the data, two large-capacity non-volatile memorys store the data alternately in the order to improve storage rate.
