摘　　要：针对现有的日光温室环境监测系统在高原地区使用时出现的高原不适应、数据传输过程中易受干扰以及重内部环境监测轻外部环境影响等问题,结合高原地区的网络情况和电气特性,提出了一种基于NB-IoT的高原日光温室环境监测系统。通过构建无线传感器网络,实时采集、上传温室内外两侧的环境非生物因子,监测信息经BC35-G通信模块上传至EMQX服务器后转发到微信小程序端展示,实现了远距离、低功耗的日光温室内外环境监测。测试结果表明,系统能够持续稳定地采集、上传温室内外的环境非生物因子,使农户能在异地实时监测温室的情况,并接收异常报警,具有较强的高原适应性,对高原设施农业的发展有着重要意义。Aiming at the problems of plateau inadaptability,susceptibility to interference during data transmission,and emphasis on internal environmental monitoring while neglecting external environmental impact when the existing solar greenhouse environmental monitoring system is used in plateau areas.Combined the network conditions and electrical characteristics of plateau areas,a monitoring system of plateau solar greenhouse environment based on NB-IoT was proposed.By building a wireless sensor network,real-time collection and uploading of environmental non-biological factors on both sides of the greenhouse,the monitoring information was uploaded to the EMQX server via the BC35-G communication module and then forwarded to the WeChat applet for display,realizing long-distance,low-power consumption environmental monitoring inside and outside the solar greenhouse.The test results show that the system can continuously and steadily collect and upload environmental non-biological factors inside and outside the greenhouse,enabling farmers to monitor the conditions of the greenhouse in real time in different places and receive abnormal alarms.It has strong plateau adaptability and is suitable for the development of plateau facility agriculture.It is of great significance.
