该系统是一个专门为温室大棚温湿度控制而设计的智能系统.通过对系统的硬件部分和软件部分设计来达到监控要求.硬件部分实现了对温湿度传感器模块、A/D转换模块、显示模块、控制模块的设计；软件部分主要根据系统的设计思想设计出了主程序和子程序流程图,并通过汇编语言和C语言实现.通过实践证明,该系统具有性能好、操作方便等优点,实现了对温湿度的显示、调节、自动控制和手动控制.%The greenhouse temperature and humidity monitoring system was an intelligent system, which was specially designed for the controlling of temperature and humidity in the greenhouse, and it could meet the demand of monitoring and controlling through the design of hardware and software. In hardware part, the designs of temperature and humidity sensor module, A/D transition module, display module and control module were realized. In software part, according to the design thoughts of the system, the flow charts of the main program and subprogram were designed, and they were realized by assembly language and C language. The practise proved that this system had the advantages of good performance and easy operation, and could realize the display, regulation, automatic controlling and manual controlling of temperature and humidity.
