【摘要】：随着我国现代化进程的快速推进,传统农业大棚监控系统的通信方式及监控模式越来越不能满足我国日益发展的需求。传统的农业大棚多采用现场布线的方式,造成现场线路的不顺畅,同时给施工和维护方面也带来不小的困难。另外,现场采集的数据都会存储在本地计算机中,这不但使数据的安全性存在威胁还对查询的时间地点进行了束缚。针对上述问题提出了基于云管理的农业大棚控制系统的总体设计解决方案。整个系统包含两大部分:底端数据采集以及云端数据处理部分。数据采集采用ZigBee无线通信的方式,通过在云数据中心创建和管理虚拟机的方式对上传来的数据参数进行统计分析。云端是各种硬件、软件、计算、存储、服务、网络等软硬件构成的资源池,大棚用户或管理者只需拥有上网的终端设备,就能访问大棚的环境参数,如实时显示和历史曲线等。这些都会通过现场监控设备备份当中,并且具有极高的安全性,领导者不必担心泄露商业机密。云布署方式采用混合云的架构,既包含公有云也包含私有云。公有云部分数据对外公开,企业和个人都可以访问,可以更好地了解企业文化交流种植技术等等,私有云供企业内部使用,负责存储一些重要资料以及参数设置。在现场监控部分当中,完成了对于数据的无线采集及传输部分的节点(包含协调器节点、终端节点等)编程,同时用VB软件在本地监控部分编写上位机监控画面。本地数据上传至云端数据库,通过Web编写代码,实现外网终端以网页的形式访问大棚数据。测试结果表明:ZigBee无线传感网络中各个节点通信正常,采集环境参数并上传至本地监控及云平台,在现场的监控画面中可以查询数据的实时显示和历史数据曲线,不在现场通过授权的人只需一部能上网的终端就可以访问云平台的数据,证明了该系统具有较好的稳定性与实用性,符合大棚的管理要求。
[Abstract]:With the rapid progress of modernization in China, the communication mode and monitoring mode of the traditional agricultural greenhouse monitoring system can not meet the growing needs of our country more and more. The traditional agricultural sheds mostly use the way of wiring on the spot, which results in the unsmooth line on the spot, and also brings difficulties to the construction and maintenance. In addition, the data collected in the field are stored in the local computer, which not only threatens the security of the data, but also restricts the time and place of the query. In view of the above problems, the overall design solution of the agricultural greenhouse control system based on cloud management is put forward. The whole system includes two parts: bottom data acquisition and cloud data processing. ZigBee wireless communication is used to collect data, and the data parameters are statistically analyzed by creating and managing virtual machine in cloud data center. The cloud is a resource pool composed of hardware, software, calculation, storage, service, network and so on. The greenhouse users or managers can access the environmental parameters of the greenhouse, such as real-time display and history curve, as long as they have the terminal equipment to access the Internet. These are backed up through on-site monitoring devices and are extremely secure, and leaders do not have to worry about leaking trade secrets. Cloud deployment uses a hybrid cloud architecture that includes both public and private clouds. The public cloud part of the data is open to the public, enterprises and individuals can access, can better understand the corporate culture exchange planting technology, private cloud for internal use, responsible for storing some important data and parameter settings. In the field monitoring part, the nodes (including the coordinator node, terminal node, etc.) of the wireless data acquisition and transmission part are programmed. At the same time, VB software is used to write the monitor screen of the host computer in the local monitoring part. The local data is uploaded to the cloud database, and the code is written by Web to realize the outer network terminal accessing the shed data in the form of web page. The test results show that each node in the ZigBee wireless sensor network has normal communication, collects the environmental parameters and uploads them to the local monitoring and cloud platform, and can query the real-time display and historical data curve of the data in the scene monitoring screen. It is proved that the system has good stability and practicability and meets the requirements of the management of the greenhouse. The data of the cloud platform can be accessed only by a terminal that can be connected with the Internet by the person who is not authorized on the spot, which proves that the system has good stability and practicability.
