摘要
本系统采用单片机AT89S51作为中央处理器,并扩展8155和8279等芯片构成最小控制系统,控制外圈模块实现相应功能。在设计制作过程中,采用外围时间芯片DS1302计时、数字温度传感器DS18B20采集温度,通过可控硅组成的开关电路驱动输出。
This system adopts single-chip computer AT89S51 as the central processing unit, besides, there are such expanded chips as 8155 and 8279, etc. They form the minimum control system, controll ing the peripheral module and realizing the corresponding function. During the designing Chip using DS1302 times; digital temperature sensor DS18B20 picks temperature to adopt peripheral time; the silicon controlled rectifier is used for switching drive and export.
