新型出租车计价器软件功能分析与实现

摘要

The design method of a new type af taximeter based on SCM is introduced. The working principle of the taximeter and corresponding error analysis are described, and some of the programmed designs are presented. All the calculation of the distance and time can be finished within 33. 9ms, which is the minimum time span when a wheel turning around. The design is featured by the flexibility and high accuracy, and its function of data statistic provides the most substantial information to the taxi administrative department for their decision making.%介绍一款基于单片机的新型出租车计价器设计方法.详细介绍计价器计程、计时、统计功能的实现原理,并依次做了误差分析,同时还给出了部分软件设计流程.计价器在车轮转一图最少需要的33.9 ms内,可以完成所有计程、计时的计算.软件设计灵活,误差小.统计功能的设计为出租车管理部门制定合理决策提供了最详实的依据.
