【摘要】：为了改善日光温室大棚内的昼夜温度更适合作物的生长,利用大棚支撑骨架和水作为热循环的主体,白天吸收太阳能并储存,晚上将储存的能量释放给温室加热。借助无线传感器网络设计太阳能集热调温系统,系统主要由温度采集、执行节点和中心决策节点组成,通过采集室外温度、骨架内水温和棚内温度,中心决策节点再根据控制策略将相应的指令发送给对应的执行节点对循环泵、阀门和加热设备进行控制,从而实现对棚内温度的自动智能调节。通过对比试验发现,设计的太阳能集热调温系统工作稳定,可提高夜间大棚内的平均温度(达2.78℃),避免作物被冻伤而减产,还可平衡中午棚内过高的温度,将其控制在最适宜的范围(20~25℃)内,从而有效延长作物进行光合作用的时间,更利于作物的生长。
[Abstract]:In order to improve the temperature of day and night in the greenhouse, the greenhouse supports the skeleton and water as the main body of the thermal cycle, absorbs and stores the solar energy during the day, and releases the stored energy to the greenhouse at night. With the help of wireless sensor network, the solar energy heating and regulating system is designed. The system is composed of temperature collection, execution node and central decision node. According to the control strategy, the central decision node sends the corresponding instruction to the corresponding executive node to control the circulating pump, valve and heating equipment, so as to realize the automatic intelligent adjustment of the temperature in the shed. It is found that the designed solar energy heating and regulating system can improve the average temperature (up to 2.78 鈩，
