茶园可视化农业气象信息动态监测预警系统研制及试验

Development and experiment of the visual agriculture meteorological information dynamic monitoring and warning system in tea garden

摘要:

为降低农业气象灾害对茶叶生产带来的不利影响，提高茶叶生产气象服务及灾害预警的业务能力和效率，利用微电子测量技术、3G无线通信与控制技术、气象和农情信息可视化技术等，并通过远程服务器端监控和管理软件的搭建，自主设计和研制了一套茶园可视化农业气象信息动态监测预警系统。该系统实现茶园图像信息、温湿度、降水数据的一体化采集和综合显示的功能。通过2014—2016年近三年的外场试验，结果表明：系统运行稳定，能及时采集和上传气象要素和图像信息，数据传输从不丢帧；解决了常规茶园自动气象站无法采集图像和微弱降水的短板和难题；外场试验中计算的平均传输速率为41.2 KB?s-1，能满足实际业务需求；借助该系统即可实时知悉茶叶长势、茶园气象信息和气象灾害等。该系统的部署及试验，为开展茶叶气象服务提供理论和技术支撑。

Abstract:

In order to reduce the adverse effects of Agriculture meteorological disasters on tea production, and improve operational capacity and efficiency of tea meteorological service and disaster warning, a visual tea meteorological Information dynamic monitoring and warning system was independently developed. Electronic measurement technology, 3G wireless communication, control technology, meteorological and agricultural information visualization technology, together with the monitoring and management software builded on the remote server were used in this system, which realized the functions of integrated collecting and displaying the image, temperature, humidity and precipitation data of tea garden. Through two years’ field experiments from 2014 to 2016, the results show that the system works stable. This system can collect and upload meteorological elements and image information timely, frames were never dropped. It solved the short board and difficult problem of conventional tea garden automatic weather station unable to collect images and weak precipitation. The average transmission rate calculated in the field experiments was 41.2 KB?s-1, which meets the actual operational requirements. With the help of the system, people can know the real-time growth, meteorological information and disasters of the tea garden. The deployment and experiment of this system provide theoretical and technical support for tea meteorological service.
