基于无线传输的竞走训练智能裁判系统的研究

A Study on Walking Race Training Intelligent Judge System Based on Wireless Transmitting

根据竞走运动的特点,设计了一种基于无线传输的竞走训练裁判系统。本系统主要有竞走犯规信号的捕获、信号的无线传输和USB上传等功能。主控制芯片采用超低功耗单片机MSP430F133,连接DS1302时钟芯片、Nord ic公司的无线收发芯片nRF905、Cygnal公司的UART转USB芯片CP2101等。给出了电路的设计,试验表明该系统取得了一定的预期效果,验证了系统的可行性。

From the characteristics of walking race, the paper presents a walking race training intelligent judge system based on wireless communication. The system has as its main functions of capturing the foul information, wireless communication and USB up-link. It makes use of uhralow power consumption SCM MSP430F133 main controller chip, interfaced with DS1302 clock chip and nRF905 made by Nodic company and UART - USB converter CP 2 1 0 1 chip made by Cygnal company etc . . The detailed design of circuits is given, which has ultralow power consumption, high degree of integration and simplicity showing the excellency of the circuitry. Expected effect and feasibility of this system are achieved.
