基于LoRa传输的农业大棚监测系统设计

Design of Agricultural Greenhouse Monitoring System Based on LoRa Transmission

科学技术的提高将农业向智能化方向推进。对于农业大棚监测系统的设计,利用了传感器采集大棚里的温度、湿度等数据,通过下位机对其进行处理调控相应控制设备;下位机通过LoRa技术将数据发送给主机,实现低功耗、长距离、高稳定性传输。主机可与多个下位机进行多机通信,远程控制相应设备,并通过GSM与用户手机进行双向的信息传输。用户通过手机可以查看控制大棚内环境变化。利用了LoRa远距离、低功耗的无线通信特性,较好地解决了传统人工监测而产生的偏差和疏漏,使用户不必居住在大棚附近也可监测、调整大棚环境,改善大棚内农作物的生长环境。

The improvement of science and technology will promote agriculture to the direction of intelligence. For the design of monitoring system for agricultural greenhouse,the temperature and humidity data in the greenhouse are collected by sensors,and the corresponding control equipment is processed and regulated by the lower computer. The lower computer transmits data to the host through LoRa technology to achieve low power consumption,long distance and high stability transmission. The host can communicate with multiple lower computers in multiple machines to remotely control the corresponding devices,and transmits two-way information through GSM and the user’s mobile phone. The user can view and control the environmental changes in the greenhouse through the mobile phone. By utilizing LoRa’s long-distance and low-power wireless communication characteristics,the deviation and omission caused by traditional manual monitoring can be well solved,so that users can monitor and adjust the greenhouse environment without living near the greenhouse,and improve the growth environment of crops in the greenhouse.
