摘　　要：温室大棚是种植反季农作物的重要设施,棚内环境参数直接决定了农作物的生产质量和数量;然而,现有的测控系统由于受天气条件等因素的影响,导致环境温湿度测试存在一定的误差;为了满足农作物的生长需求,并提高精确度,提出了基于LoRa无线传感网络的农业温室大棚环境测控系统的优化设计;通过改装传感器设备和调整数据处理器和控制器的内部结构,构建了系统数据库并组建了LoRa无线传感网络,实现了实时采集大棚环境数据和传输到系统终端;通过计算调整控制量,实现了对农业温室大棚环境的测控功能;实验结果显示,与传统测控系统相比,优化设计的系统在环境温湿度测试方面的误差显著降低了,分别降低了3.65℃和3.75%。Greenhouses are an important environment for planting off-season crops,and the environmental parameters of greenhouses directly determine the production quality and quantity of crops.However,existing measurement and control systems have certain errors in environmental temperature and humidity testing due to factors such as weather conditions.In order to meet the growth needs of crops and improve accuracy,an optimized agricultural greenhouse environment measurement and control system based on LoRa wireless sensor network is proposed.By modifying the sensor equipment and adjusting the internal structure of data processors and controllers,the system database and LoRa wireless sensor network are established,and the real-time environmental data of the greenhouse are collected to transmit the system terminals.The control variables are calculated and adjusted to achieve the measurement and control function of the agricultural greenhouse environment.Experimental results show that compared with traditional measurement and control systems,the optimized system significantly reduces the errors of environmental temperature and humidity by 3.65 ℃ and 3.75%,respectively.
