大学毕业设计作品：出租车计价器的设计：以AT89S52单片机为中心，通过金属传感器来测距，实现对出租车的计价统计。结合语音芯片ISD4004，时钟芯片DS1302，功放模块LM386N组成语音时间控制系统，最后通过液晶显示模块LCD12864显示单价、路程、总价、时间等。本系统可以实现单价、起步价、白天价、夜间价的显示和时间的修改。AT89S52通过P0口与外部语音报价电路相连，可以实现语音报价功能。-Graduated from college design work: the design of a taxi meter: The AT89S52 microcontroller as the center, ranging through the metal sensor to achieve statistical valuation of the taxi. Combination of voice chip ISD4004, clock chip DS1302, composed of voice amplifier module LM386N-time control system, the final adoption of liquid crystal display module LCD12864 show unit price, distance, total price and time. This system can achieve unit price, starting at daytime price, prices shown at night and the time changes. AT89S52 through the P0 port with an external circuit connected to voice offer, you can offer voice functionality.
