双协议融合的WSNs温室环境监控系统设计

针对温室环境数据无线采集、视频监控及远程管理的需求，设计了一种基于无线传感器网络（ WSNs）的智能温室环境监控系统。系统采用ZigBee和WiFi融合通信技术组成智能网关，其中，ZigBee无线通信设备用于采集温室环境数据，WiFi通信设备用于无线视频传输和远程通信。所设计系统既避免了传统温室环境有线监控安装和维护的繁琐，同时解决了ZigBee WSNs传输速率较低、无线传输距离较近的缺点，温室环境监控功能得到拓展。经过测试验证，正常情况下网络丢包率小于1%，系统实现了温室环境远程监控管理的各项性能，具有良好的应用性和可扩展性。

Design of WSNs monitoring system for greenhouse environment based on fusion of dual-protocol

Aiming at requirements of greenhouse environment data wireless acquisition,video monitoring and remote management,a kind of intelligent monitoring system for greenhouse environment based on wireless sensor networks( WSNs )is designed. The intelligent gateway is composed of ZigBee and WiFi fusion communication technology,the ZigBee wireless communication device is used for data acquisition of greenhouse environment,and WiFi communication equipment is used for wireless video transmission and remote communication. The system not only avoids cumbersome installation and maintenance of cable monitoring,but also solves shortcomings of low transmission rate and short transmission distance of ZigBee WSNs,greenhouse environment monitoring function is expanded. Validation test results show that, the network packet loss rate is less than 1 % under normal circumstances,the proposed system realizes performances of remote monitoring and management,and has good applicability and scalability.
