基于单片机多功能码表的设计

Design of Multi-function Code Table Based on Single Chip Computer

设计了一种以51系列单片机STC89C51作为主控芯片,能够显示时间、温度、速度、里程和方位四种功能于一体,应用于户外运动旅游的多功能码表系统。该码表采用的外围元件温度传感器DS18B20,可对户外的温度进行感知;时钟芯片DS1302,在户外也可以知道当前的时间;霍尼韦尔传感器主要是对骑行运动的速度进行测量;三轴数字罗盘HMC5883L是对户外所在方向进行指示。利用单片机制作的码表,经过用户的使用验证,码表系统的四种功能显示较为稳定而且价格低廉,功耗低,非常适用于喜欢户外旅行爱好者使用。

Designed a kind of 51 series microcontroller STC89C51 as main control chip, can display time, tempera- ture, speed, range and azimuth four functions in an organic whole, multifunction clock system applied in the outdoor sports tourism. The external temperature sensor DS18B20 is used in this code table, which can be perceived by outdoor temperature. The clock chip DS1302 can also know the current time outdoors. Honeywell sensors are mainly measuring the speed of cycling. The three-axis digital compass HMC5883L is the direction of the outdoor direction. Using MCU clock, through the use of user authentication, the meter system of four functional showed more stable and the price is low, low power consumption, very suitable for like outdoor travel.
