水稻育种环境测控系统的设计

Rice Breeding Environment Measurement and Control System

针对水稻育种的复杂过程,以单片机STC89C52为控制核心,完成了水稻育种环境测控系统的软硬件设计。其中,DHT11为温湿度传感器,DS1302为系统时钟模块,LCD12864为显示模块,nRF905为无线收发模块。该系统能够实时显示当前的温湿度值和日期,用户可以自行设置合适的初始温湿度和计时时间,单片机实时采集外界信息参数,与设定的范围值相比较,当外界信息参数值不在设定值范围内时,报警系统打开,启动执行装置,实现温湿度的控制。

Aiming at the complex process of rice breeding, based on STC89C52 MCU and taking it as the core, this essay has completed the rice breeding environment measurement and control system＇s hardware and software design, which choose DHTll as temperature sensor, DS1302 as system clock module, LCD12864 as display module and nRFg05 as wireless transceiver module. The design can display the current date, tempera- ture and humidity values, the user can set their own appropriate time, temperature and humidity initial values. We measured the external information parameters input to the MCU to compare with the set range values. When the outside information parameter values exceed the set value range, it opens the alarm system and acti- vates the relay to achieve temperature and humidity control.
