摘　　要：针对温室水肥精准灌溉问题,以温室环境参数和土壤参数为检测对象,基于DSP搭建了温室水肥控制系统,进行参数实时采集上传.应用LabVIEW构建了上位机监控平台,对温室环境参数进行实时监测显示,并对采集到的海量数据进行云端存储.考虑各环境参数与水肥之间的相互影响,综合各参数关系,采用三级模糊控制的方式,给出灌溉量和施肥量的预测值.利用LabVIEW和MATLAB的协同调试,将灌溉和施肥控制指令下发给下位机核心处理器,对水肥控制阀门进行控制,达到温室内灌溉和施肥之间的自动控制.To make greenhouse irrigation of water and fertilizer precise,a greenhouse water and fertilizer control system was built based on DSP to collect and upload parameters in real time.LabVIEW was used to build an upper computer moni-toring platform for real-time monitoring and display of greenhouse environmental parameters.Taking into considerationthe interaction between environmental parameters and water and fertilizer,the amount of irrigation and fertilizer was predicted by three-level fuzzy control.With the help of LabVIEW and MATLAB,the irrigation and fertilization control instructions were sent to the core processor of the lower machine to realize the automatic control ofirrigation and fertilization in the greenhouse by monitoring the water and fertilizer controlling valve.
