【摘要】：温室集群管控是采用科学化的生产和管理方式,实现高效可持续发展的现代化温室发展方式。面对多变的自然气候环境,作物生命活动的特性,构建温室集群管控平台是志在必行的。温室集群管控平台能够根据生产作物的生长习性和市场需求,部分或者完全摆脱自然环境的束缚,创造出一个有利于作物生长的最佳环境,生产出高品高质的产品,满足市场需求。且该平台很好地兼顾了生产效率和成本投入,保证生产。温室内常年处于高温高湿的环境,肥料的施用也会给土壤或空气中的酸碱度带来影响,这点为传感器网络的布设带来不小的难度。无线传感器网络的应用能够减少温室特殊气候环境对传感器及线路的损坏,降低维护成本,且简化了传感器的增设工作。本文研究的温室集群管控平台针对苏州御亭农业现代化产业园区建设特点,基于无线传感器网络的布设获取温室集群的各项环境因子数据信息,对数据进行存储和处理,便于园区用户查看其变化情况,并通过多种控制方式实现了对温室内环境的有效管理控制。且园区管理员级别用户能够通过后台对平台进行管理,调整控制方式的具体策略。其中,数据监测模块是本平台建设的基础。它利用遵循ZigBee协议的无线传感器网络,自动监测采集温室环境内的各项环境因子数据,发送至服务器,存储到传感器网络数据数据库中。为用户提供便利的实时查询、历史查询、曲线查询服务。智能控制模块是温室集群管控平台建设的重点。包括专家控制、定时控制和手动控制。对温室执行机构控制过程中,用户可以选择不同的控制方式,或通过专家决策信息,或依据自身生产习惯和经验设置温室执行机构定时启用计划,或直接通过网络平台的执行机构开关按钮,来对执行机构开/关进行控制。三项控制方式为用户提供了多样且有效的温室控制。后台管理模块是温室集群管控平台建设的支撑。园区管理员被授权负责对平台用户进行管理,对作物不同阶段生长所需环境因子的阈值进行修改和保存,并且可以修改和保存温室执行机构的开/关策略。为用户提供了一个灵活有效的平台调整管理方式,使整个平台的工作运行能更加贴合产业园区的实际情况。本平台在设计和实现过程中,综合利用各项技术,依据产业园区实际需求及生产特色,希望建设一个能较好满足实际生产过程,具有良好应用价值的温室集群管控平台。
[Abstract]:Greenhouse cluster management is a modern greenhouse development mode which adopts scientific production and management to realize efficient and sustainable development. In the face of the changeable natural climate environment and the characteristics of crop life activities, it is necessary to build a greenhouse cluster control platform. The greenhouse cluster control platform can partly or completely get rid of the constraints of natural environment according to the growth habits and market demand of the production crops, create an optimal environment for the growth of crops, and produce high quality and high quality products. Meet market demand. And the platform has a good balance between production efficiency and cost input to ensure production. The greenhouse is in the environment of high temperature and high humidity all year round, and the application of fertilizer will also affect the pH of soil or air, which makes it difficult to lay out the sensor network. The application of wireless sensor network (WSN) can reduce the damage of sensors and circuits caused by the special climate environment of greenhouse, reduce the maintenance cost, and simplify the work of adding sensors. The greenhouse cluster control platform studied in this paper aims at the characteristics of the construction of Suzhou Yuting Agricultural Modernization Industrial Park, and acquires the environmental factor data information of the greenhouse cluster based on the arrangement of wireless sensor network, and stores and processes the data. It is convenient for the campus users to view the changes and realize the effective management and control of the greenhouse environment through various control methods. And the campus administrator level user can manage the platform through the background, adjust the specific strategy of the control mode. Among them, the data monitoring module is the foundation of this platform construction. It uses the wireless sensor network (WSN) following the ZigBee protocol to automatically monitor and collect the environmental factors data in the greenhouse environment, send them to the server, and store them in the database of the sensor network. Provide users with convenient real-time query, history query, curve query services. Intelligent control module is the focus of greenhouse cluster control platform construction. Includes expert control, timing control and manual control. In the process of controlling the greenhouse actuator, the user can choose different control methods, or set up the greenhouse executing agency regular opening plan according to his own production habits and experience, either through the decision information of the expert or according to his own production habits and experience. Or directly through the network platform actuators switch button to control the actuator on / off. Three control methods provide users with diverse and effective greenhouse control. Background management module is the support of greenhouse cluster management platform construction. The campus administrator is authorized to manage the platform users, modify and preserve the threshold of environmental factors required for different stages of crop growth, and modify and preserve the opening / closing strategies of the greenhouse implementing agencies. It provides a flexible and effective way to adjust and manage the platform so that the work of the whole platform can be more in line with the actual situation of the industrial park. In the process of design and implementation, the platform synthetically utilizes all kinds of technologies, according to the actual demand and production characteristics of industrial park, and hopes to build a greenhouse cluster management and control platform which can meet the actual production process and has good application value.
