摘要
为了增强公交车报站系统的实用性,提升公交车的服务能力,设计了当前时间和温度的显示。采用串行时钟芯片DS1302进行时间获取,用单总线数字温度传感器DS18B20进行温度采集,将得到的信息经单片机处理送到LCD显示。详细给出了与单片机AT89C51接口的软硬件设计,通过Proteus仿真平台验证了系统运行的准确性与可靠性。该设计硬件简单可靠,软件编程容易,可方便地移植到其他家用电器或工农业生产等实时控制系统中。
In order to enhance the practicality of the bus-stop system and enhance the capacity of bus services, the design of the current time and temperature display. The use of serial time clock chip DS1302 for acquisition time, single-bus digital temperature sensor DS18B20 for temperature collection, the information dealt with by the MCU and transported to the LCD display. The hardware and software design of the interface contact with MCU is described in detail,the accuracy and reliability of the system running was verified through the Proteus simulation platform. The hardware design was simple and reliable, software programming was easy and can be transplanted to other home appliances or industrial and agricultural production real- time control system.
