分析了温室系统的温度特性,指出温室的加热过程是一个惯性较大、滞后时间较长的复杂过程,还介绍了用于温室控制的计算机系统。系统以单片机为下位机,以PC机为上位机。下位机主要完成温室内温湿度的测量、数据处理、输出控制以及与上位机进行通信等任务;上位机主要完成设定下位机的控制参数、监测温室内的状态以及保存下位机传送过来的实时数据等任务。
The temperature characteristics of the greenhouse system are analyzed. It is pointed out that the heating process in the greenhouse is a complex process with larger inertia and longer lag time. The computer system for greenhouse control is also introduced. System to microcontroller for the next crew to PC for PC. The lower computer mainly accomplishes the tasks of measuring the temperature and humidity in the greenhouse, data processing, output control and communication with the upper computer. The upper computer mainly completes the setting of the control parameters of the lower computer, monitors the state in the greenhouse and saves the real-time Data and other tasks.
