Abstract
|
This article mainly introduced the aircraft engine temperature testing system based on embedded computer system design principle and implementation method. The temperature testing system of high precision, strong anti-jamming capability, good stability. This paper introduces the research background, the paper analyzes the significance of research. Briefly describes the necessity of temperature detection, temperature measuring method and natural engine hot test technology. Introduced the system with embedded computer as the core temperature of the working principle and hardware design and software design of the system. Ptl000 and expounds the use of thermal resistance measuring temperature cold junction compensation of thermocouple method. In the hardware design process and method of realization of each function module are introduced; First introduced the software is introduced in the design of the software development platform and software function block diagram, the focus in this paper, the design of the human-computer interaction interface, A/D conversion, D/A conversion, digital filter and the design of the database program. And introduced the system hardware and software anti-interference measures and system debugging process and result. Finally, the design work of this paper are summarized. According to the results of the debugging, and measuring the temperature test system is stable, reliable operation has reached the design target.
