摘要
随着教育部对学生身体素质要求的提高,体能考核逾显重要。但在日常体能考核过程中存在诸多困难:其一,学生人数多,测试费时费力;其二,人工计时差错较多,并由此引发许多争议。为了能够自动统计大量人群的长跑成绩,设计并实现了一种基于MSP430单片机的新型长跑计圈计时系统。该系统能够自动计圈计时,节省了大量人力,并且具有超低功耗、重量轻、稳定可靠等优点,在长跑测试使用中十分方便。简要介绍了处理器MSP430的功能和特点,详细分析了该系统的电路组成和软件结构。该系统结构简单合理,目前已经得到批量制作并投入使用。
With the increasing demand of high physical qualities of students by ministry of education, the physical evalua- tion gains more and more importance. But there are many problems during the physical evaluation process. First, it requires much time and energy to conduct the testing because of the large number of students. Second, the practice of manual timing may lead to false statistics results thus to some controversy. In order to count the results of long - distance running of a great deal of people automatically, a new MSP430 -based circle -counting and timing system is designed and completed. This system can accomplish the circle - counting and timing task automatically by which can save energy as well as reach the advantage of low power consumption,light weight and stability. So it is very convenient for the long - distance running testing. This paper briefly introduces the functions and features of the processor MSP430 and explains the circuit components and software structure of the system. With the simple- structure and reasonable designing feature,this system has now been in mass production and widely use.
