便携式自行车功能仪的研究

摘要

基于实现自行车使用过程中方便地了解速度里程等相关信息以及使用者的身体情况的目的, 采用以MSP430单片机为微处理器完成了便携式自行车功能仪测控系统设计方案,并完成系统的软硬件设计.系统实现温度测量、行驶里程及速度、血压及心率测量和实时显示于一身的便携式自行车功能仪系统. 系统的硬件部分主要设计各个测量参量传感器模块选择与设计以及与微处理器的接口设计,软件部分采用IAR for MSP430进行编程,实现对采集到的多个实时信号进行分析处理实现设计要求. 通过实际调试,系统可以稳定,快速得实现速度、里程、环境温度、使用者血压和心率等多个参量的实时测量与显示,并对超速,高血压进行报警,操作简单,使用方便,达到了设计要求.%Based on implementing bicycle use process easily understand the speed range and other relevant information as well as the body of the user, the purpose of using MSP430 single chip microcomputer as the microprocessor finished the portable bike function instrument measurement and control system design, and complete the hardware and software design of the system. System to realize the temperature measurement, the range and speed, blood pressure and heart rate measurement and real-time display of portable bike function instrument system. The hardware part of the system main design various measurement parameter selection and design sensor module and microprocessor interface design. Software part can be programmed using the IAR for MSP430 realize the collected multiple real-time signal analysis and processing to achieve the design requirements. Actual commissioning, the system can stabilize quickly get real-time measurement of multiple parameters of speed, mileage, temperature, blood pressure and heart rate and user display, and speeding, high blood pressure alarm, simple, easy to use, to the design requirements.
