摘要
设计了一种完成温度检测、输入、运算和输出控制以实现对果蔬仓库内温度控制的新型果蔬仓储温度控制系统。该系统以AT89C51单片机为核心,能对多点的温度进行实时巡检和控制。测量结果不仅能在本地显示,而且可以利用单片机串行口,通过RS-485总线及通信协议将采集的数据传送到上位机。上位机与下位机之间能够相互联系、相互协调,使系统整体达到统一、和谐的效果。
A new temperature control system of fruits and vegetables warehousing that could complete the temperature examination, the input, operates and the output control so as to realize the temperature control in the warehouses of fruits and vegetables was designed. AT89C51 monolithic integrated circuit was taken as a core, the multi-spot temperature was real-time inspected and controlled. The measurement result was not only displayed in local areas, but also was transferred to superior machine through the RS-485 main line by using the monolithic integrated circuit serial port and the communication protocol. The connection and coordination of superior machine and lower position machine achieves the unification and harmonious effect of the system.
