农村温室养殖温度控制器设计与实现

Design and Implement on the Temperature Control System of Greenhouse in Rural

随着单片机技术的飞速发展及其成本的降低,基于提高农业生产效率和改善劳动环境舒适性的自动化控制得到了发展。结合设施农业的温室大棚养殖中的具体要求,研制了一套面向农村地区的低成本的温度监控器,给出了详细的软硬件设计。该系统采用开关电源,有效地降低了因电压不稳对系统的影响,提高了电源的利用率,具有成本低、安全性高和实用性强等特点。

With the continuous development of the electronics technology and the dropping cost of SCM, the standard of the automation control, aimed to reduces labor strength and improves work efficiency , have been developed rapidly. In light of the demanding in applying temperature controller in greenhouse of protected agriculture, the paper proposes a lower cost temperature controller. The process of design hardware and software has been described in detail. SMPS technology has been used in the controller that can reduce the from mains voltage fluctuation. With lower cost, high security and strong practicability, the control system can meet the needs of rural area.
