The Aircraft Engine Temperature Test System Based On Embedded Computer System

This paper Introduces design principles and implementation of the engine temperature test system for aircraft based on embedded computer system. The high accuracy temperature measurement system was characterized by good anti-interference ability and working stably .This paper first introduces the subject of the background and analysis of the significance of the research. This paper briefly describes the need for temperature measurement, temperature measurement methods and high temperature aircraft engine testing technology. And then this paper introduces the whole design of the system based on embedded computer system as the core temperature of the working principle and system hardware design and software design, the thermal resistance Ptl000 was used to measure environmental temperature for the cold-junction compensation of thermocouple. In the hardware design describes each function module implementation process and methods. In software design, first introduced the software development platforms and software functionality diagram, focuses on human-computer interface design, A / D converter, D / A conversion, digital filtering and database program design. And this paper introduces the system of software and hardware anti-jamming measures and system debugging process and results. Finally, the design of this work is summarized.According to debug and test results, the temperature test system is stable, reliable and meet the design expectations.
