物联网温室群双模糊控制系统的设计

Design of Double Fuzzy Control System for IoT Greenhouse Group

受普遍缺水的国情及现代种植业向着产业化和规模化发展趋势的影响,设施农业得到了长足发展。我国的温室面积不断扩大,且温室中的种植作物也日趋丰富和多变。为实现对温室群的统一准确调控与各温室不同作物的科学种植,提出了一种远程服务器与物联网技术相结合的调控系统。调控系统以嵌入式Web服务器为核心,结合STM32单片机为底层控制器,采用Modbus通信协议实现温室群与控制端的信息动态交流。同时,现场控制器增设SD卡功能及双模糊规则,实现了在通信受阻状况下温室数据的本地保存及对环境参数的准确控制。用户可通过Internet访问服务端,借助浏览器或网关端的首部控制柜参考数据库内写入的科学种植决策和上传温室各类环境参考数据,即可实现对各温室环境多因子参数的合理调控。控制端多种自动控制方法的集成为用户提供了丰富的选择,对实现温室群科学高效化管理具有重要的实际应用意义。

Affected by the general lack of water and the influence of modern planting industry on indust-rialization and scale development,facility agriculture has made considerable progress.The greenhouse ar-e a in China is constantly expanding.At the same time,crops grown in the greenhouse are becoming more abundant and variable.In order to realize the unified regulation of the greenhouse and the scientifi-c managementof different crops,a control system combining remote server and Internet of Things techn-oloy is proposed.The control system takes the embedded Web server as the core,and combines the ST-M2 MCU to implement the dynamic communication of the information between the greenhouse group a-nd the Control terminal by using the MODBUS communication protocol for the underlying controller.Inaddition,the on-site controller adds the SD card function and double fuzzy rules,which realizes the loca-l storage of greenhouse data and accurate control of environmental parameters when communication is b-locke.User can access the server through the Internet or the gateway’s first control cabinet to refer to th-e scie Ntificplanting decisions written in the database and upload various greenhouse environmental refer-ence data to achieve reasonable regulation of multi-factor parameters in each greenhouse environment.A-t the same time,the integration of various automatic control methods on the control side also providesusers with more choices.It has important practical application significance for realizing scientific and effi-cient management of greenhouse groups.
