基于 GSM 的设施农业气肥监控系统设计与实现

摘要

针对现有CO2监控设备存在操作复杂、控制方式不科学、CO2利用率低等不足，结合我国家庭式小规模农业生产现状，设计了一种基于 GSM 的设施农业气肥监控系统。系统以 STC12C5A60S2单片机为中央处理芯片，以SIM 900为通信模块，可通过 SMS 短信业务与现场控制两种操作方式对设施农业 CO2浓度进行监控及预警。结果表明，系统具有稳定性高、操作简单、成本低等特点，为我国小规模农业生产提供了一种可行、高效的CO2浓度监控方法，有效提高了设施农业生产管理水平。%To improve the weakness of operation , control mode and utilization rate of carbon dioxide in existed carbon di-oxide monitor and control equipment , this paper designed a facility agriculture gas fertilizer monitor and control system with GSM, which combines with small-scale farming.The central processor of the system is STC 12C5A60S2 and SIM900 is used as communication module .It can realize monitor and early warning of carbon dioxide concentration in Fa-cility Agriculture by SMS and field control .The results show that the system has high stability , simple operation and low cost.It provides a reliable solution for monitor and control of carbon dioxide concentration and improves agriculture pro -duction management .
