[assembly language] chuzuchejijiaqi DL : 0: 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-Taxi meter design: AT89S52 microcontroller as the center, ranging through the metal sensors to achieve statistical valuation of the taxi. Combining voice chip ISD4004, clock chip DS1302, composed voice amplifier module LM386N-time control system, and finally through the LCD display module LCD12864 price, distance, total time, etc. The system can modify the price, starting at daytime at night price display and time. AT89S52 through the P0 port is connected to an external circuit voice quotes, quotes voice functionality can be achieved
