基于WIFI的温室群多节点数据传输系统设计

Design of Multi-node Data Acquisition System of Greenhouse Group Based on WIFI

温室群是目前我国南方地区普遍采用的产业化种植模式,其电气化、信息化、智能化的要求越来越高。为了满足大数据传输和温室群信息数据汇聚和入网的需求,本文设计了基于WIFI的温室群多点数据传输系统,采用中继传输技术和自组网技术构建级联网络,有效扩大WIFI网络的覆盖范围。WIFI节点通信测试结果表明:中继数传过程约需16 s,可满足温室群多节点传输应用。

Greenhouse group is generally used in southern China industrialization planting patterns, the electrification, informationization, intellectualized demand is higher and higher. To achieve greenhouse group concentration of information data gathering, at the same time meet the needs of greenhouse group extended the large data transfer. This paper designed multi-point data acquisition system of greenhouse group based on WIFI. The relay transmission technology and the Ad-hoc network technology, build 3 level network effectively expand the WIFI network coverage. This design the WIFI network communication test results show that 3 level network communications relay transmission stability, relay digital process needs 16 s longest, applied in monitoring cycle longer, less affected.
