摘要：2015年底至2016年春节前夕，一股历年罕见的寒潮席卷了我国大部分地区，南北方种植的蔬菜产量大幅度减少导致蔬菜供不应求，百姓的生活受到极大影响。采用大棚蔬菜种植的方式有效降低了自然灾害的影响，并可以反季节种植，能更好地满足当前社会的需求。对大棚种植环境的深入研究，配置合理、智能调控的大棚环境使蔬菜能够在适宜的环境中生长，达到种植效益最大化。

该课题主要研究了如何对大棚中植物生长的环境进行监测和分析，进而对植物生长进行监控和管理。系统从软件和硬件相结合的角度出发，利用温度、湿度、光照等传感器和无线传感器（ZigBee）模块采集大棚中的环境数据，之后通过协调器上传到PC端，PC端存储并分析收集到的数据，将结果显示在网页中。用户可以查阅采集到的数据，并通过折线图显示其变化趋势。这使数据显示更加直观、生动。通过设置监控对象异常数值范围，可以自动触发干预机制，实现升降温、浇水、通风、光照度等控制。最终用户可以随时在线查看和设置大棚监控信息。该设计方案优点是功能集中，部署成本低，适用范围广，便于种植人员查看和管理。76606

Abstract：At the end of 2015 to 2016 on the eve of Spring Festival, a rare cold wave swept across most parts of China。 The production of vegetable which grow in the north and the south had greatly reduced, which made the unbalance between vegetable supplies and consume, people's life was greatly influenced。 The way to using greenhouse vegetables grown is applied to solve effectively the influence of natural disasters, and can be anti-season cultivation, more in line with the current needs of society。 The in-depth study on the greenhouse planting environment, reasonable configuration, intelligent control environment makes the vegetables can grow in the appropriate environment, in order to achieve maximum benefits of planting。

The project mainly studies the monitoring and analysis of the plant growth environment in the greenhouse, monitoring and managing of plant growth。 Combining the system from hardware and software point of view of using temperature and humidity sensor and wireless sensor (ZigBee) module acquisition of greenhouse environment data, that followed by the coordinator which uploaded to the PC。 PC would collect the data, save in the database and display in a web page。 Users can access to the collected data through the line chart to display to make the data more intuitive and vivid。 By setting the value range of the monitoring devices, it can automatically trigger the intervention mechanism, and realize the control of temperature, water, ventilation, light illumination and so on。 Users can view and set the shed online monitoring information。 Now the research equipment for the greenhouse has been gradually mature, functional concentration, low cost, wide application, is easy to plant personnel to view and manage。
