| 摘 要： | 为满足温室作物对生长环境的要求,达到作物生长根上、根下环境因子检测与控制的高度集成,利用已有的作物根上环境因子CAN现场总线控制系统,设计了CAN总线的接口电路、根下营养液组分的信号采集电路、根下营养液组分控制系统.通过对营养液施加一个自适应控制量,将动态矩阵控制算法应用到营养液组分控制中;并将营养液组分控制软件集成到CAN现场总线中,实现了根上、根下环境因子的一体化控制.该算法建模简单,便于工程应用.现场运行结果表明,其控制效果良好.

| Abstract: | According to the demands of the greenhouse crops for environment,the integrative measures and controls of the greenhouse environmental factors is realized.Making use of the CAN-bus control system in the experimental greenhouse,the interface circuits of the CAN-bus,signal gathering circuits and control system of the growth factors at root level are designed.Based on adaptive control variable algorithm,dynamic matrix control is introduced to nutritive medium control system.The nutritive medium control software is combined with CAN-bus control system which works very well in practice. |
