摘要
系统以AVR的Mega 8L为控制核心,基于Keil的编程软件系统,辅以必要的外围电路和设备,实现了出租车计价器装置与模拟出租车车速装置的设计,利用合理的硬件和优化的算法设计实现了出租车计价器的基本功能并用出租车车速模拟装置进行了测试。此计价器具有速度检测、时间显示、语音功能、账单打印、参数修改、密码保护等功能,并且具有功耗低、误差小、系统稳定、人机交互友好,性价比较高等优点,必将有良好的应用前景。
This system based on AVR Mega 8L control core, based on the Keil programming software system, supplemented by necessary peripheral circuit and equipment, implement the taximeter device to simulate the taxi speed device design, using reasonable hardware design and optimized algorithm has realized the basic function of the meter taxi and taxi speed analog device was tested. This meter has the function of speed detection, time display, voice, bill printing, parameter modification, password protection, etc, and has low power consumption, small error, system stability, friendly human-computer interaction, the characteristic of high cost performance, will have good application prospects.
