摘要
设计了一个基于RS485总线网络的烤烟集中监控系统,上位机和下位机全采用单片机.上位机能远程监视和控制各下位机的温湿度数据.下位机采用X1228实时时钟芯片作时间系统和E2PROM存储器,用DS18B20数字温度传感器采集干、湿温度,并对烤房温湿度进行控制.下位机具有多曲线、自学习功能,能适应不同地域和季节的烟叶烘烤需要.
This paper designs a concentrating surveillance-control system about tobacco baking based on RS485 bus The upper machine and lower machine all employ micmcontmller. The upper machine can monitor and control the data of lower machines from afar. The lower machines utilize real time chip X1228 as its time system and E2 PROM, and employ digital temperature sensor DS18B20 collecting temperature and humidity. The lower machines have multiple curves and self-study functions, and are suitable for multiple requirements of tobacco in different areas and different seasons.
