新型农业大棚CO_2气体远程无线监测系统的设计

Design of wireless remote monitoring system of CO_2 in agricultural greenhouse

针对农业大棚CO2气体的远程实时监测问题,提出一种基于嵌入式系统开发技术和SMS无线通信技术的远程无线监测系统的设计方案。系统由大棚监测节点和用户手机两部分构成,监测节点基于ARM处理器设计实现、采用非色散红外吸收式二氧化碳传感器对CO2进行高精度检测并通过TC35I无线射频电路以SMS消息格式定时将检测数据发送到用户手机。测试结果表明,该系统监测精度高、传输距离远、运行稳定可靠,能够很好地满足农业大棚CO2气体的高性能自动化远程实时监测需求,具有较高的实用和推广价值。

In order to solve the problem of agricultural greenhouse CO2 gas remote real-time monitoring,a novel remote wireless monitoring system was designed based on embedded system development technology and SMS wireless communication technology.The system is consisted of greenhouse monitoring node and user＇s phone.The monitoring node is based on ARM processor,and the non-dispersive infrared absorption sensor of carbon dioxide is selected for high precision detection.ATC35 Iwireless circuit is used to send the CO2 data regularly to the user＇s phone by SMS message format.The system has high monitoring precision and long transmission distance,is stable and reliable in operation.It can well satisfy the requirements of high-performance automatic remote monitoring in agricultural greenhouse CO2 gas,and has high practical and promotional value.
