野外无线智慧农业信息采集与返控终端设计

The Design of a Kind of Field Wireless Intelligent Agricultural Information Acquisition and Return Control Terminal

摘要: 随着城市化进程的加快、城乡融合互动的进一步加强、休闲创意农业快速发展，新的农业形态层出不穷。现代农业设施中，已经涌现出一大批成熟的农业物联技术方案，本文提出一款应用于野外农业、低成本、低功耗的，基于177 M数传通信技术的农田信息采集与控制终端设备设计方案。该系统由前端数据采集与控制系统和数据管理中心两部份构成，数据采集与控制系统由中心网关和终端节点以及无线传感网络组成，中心网关通过177 M数据通信模块自组网收集每个终端节点信息采集点的空气温湿度、土壤水分温度、二氧化碳浓度、光照强度等信息，并通过GPRS通信网络将收集到的数据传送到数据管理中心。

Abstract: With the acceleration of the urbanization process, the further strengthening of urban and rural integration, and rapid development of leisure and creative agriculture, new agricultural formats emerge in endlessly. In modern agricultural facilities, there are a large number of mature agricul-tural technology plans. In this paper, a design scheme of field information acquisition and control terminal equipment based on 177 M data transmission technology is proposed, which is used in field agriculture with low cost and low power consumption. The system consists of two parts, the front data acquisition and control system and data management center. Data acquisition and con-trol system is composed of central gateway and terminal node and wireless sensor network. Gateway center collects terminal node acquisition information, including the air temperature and humidity, soil moisture and temperature, carbon dioxide concentration, and illumination intensity, by 177 M data communication module from the network, and the collected data is transmitted to the data management center through the GPRS communication network.
