温室大棚智能漏电保护系统的研究

Research on ground-fault protection system with intelligence in greenhouse

由于温室大棚中的温湿度变化明显,使得其中的漏电保护器不能正常动作,因此发生很多触电事故。针对中小型温室蔬菜大棚中漏电保护断路器频繁出现的跳闸故障,本文设计了一种以STC12C2052AD单片机为控制核心,能够结合温室中温湿度的变化,自动调节漏电保护器动作阀值的智能保护系统。该系统能够实时监测温室大棚中的环境变化,自动调节保护阀值,识别漏电故障,并带有声光报警功能,能够满足温室大棚的漏电保护需要,提高了大棚工作人员的用电安全。

Because of the obvious changes in the temperature and humidity in the greenhouse,the ground-fault protector can not operate normally,so many electric shock accidents occur. For the frequent tripping fault of leakage protection circuit breaker in the small and medium-sized greenhouse vegetable,the thesis comes up with intelligent protection system which automatically adjusts the leakage protector action threshold combining with the change of temperature and humidity in the greenhouse,and taking STC12 C2052 AD single-chip microcomputer as control core. This system which can improve the shed staff for safety.
