理工大学本科毕业设计（论文）理工大学本科毕业设计（论文）题目The Subject of Undergraduate Graduation Project (Thesis) of DUT气压高度表设计理工大学DalianUniversity of Technology摘 要 航空航天事业的日益进展促使航空仪表向着智能化方向进展。同时新能源在航空领域的应用，小型飞行器的研制使航空仪表出现了向低功耗方向进展的趋势。气压高度表是一种重要的航空仪表，其主要作用是向载体提供准确的高度数据。体积小、重量轻、功耗低正成为气压高度表的新的进展趋势。 基于上述原因，本文基于 ARM 系统的低功耗原理，完成了低功耗气压高度表的研制工作，主要包括整机的硬件设计，软件编程以与从硬件和软件两个角度降低功耗的设计。该气压高度表主要由数字气压传感器、主控制器、电源管理组成。 主机以意法半导体公司的 STM32F103RBT6 单片机为核心，直接读取数字气压传感器的气压信号，之后再通过气压与海拔的关系换算得到实际海拔，即高度值。关键词：气压高度表，低功耗设计，STM32，小型化设计AbstractAerospace business to the development of aircraft instruments to intelligent direction. At the same time the new energy in aviation, the application of the development of small aircraft that aircraft instruments appeared to the trend of the development of the direction of low power consumption. Air pressure altimeter is a kind of important aircraft instruments its main function is to provide accurate height data carrier. Small volume, light weight, low power consumption is becoming the new development trend of air pressure altimeter.Based on the above reasons, this paper based on ARM system of low power consumption principle, the completion of the low power consumption of the air pressure altimeter research work, including the machine's hardware design, software programming and from two aspects of hardware and software design of the lower power consumption. The air pressure altimeter digital pressure sensor, mainly by main controller and power management component.The...
