摘要
为了节约水资源,营造环保、舒适的人居环境,针对现有卫生间冲水器实时性差,误检率高,节水效果不明显等问题,提出一种基于AT89C2051单片机的嵌入式智能型节水系统设计方案。该系统采用主注水控制技术及加权控制辅注水技术,极大地缩短了冲水迟滞时间。采用基于3min检测周期的冲水机理能实时、有效地检测判断出高峰期、低峰期和无人期;采用改进的红外监测技术使红外监测的误检率降低到0.2%。现场试验结果表明,系统各项性能指标均达到设计指标要求,节水率提高到88%。
In order to save water,create the environmentally friendly and comfortable living environment,a design scheme of embedded intelligent water-saving system based on AT89C2051 is proposed for solving the existing toilet flusher,such as the poor real-time performance,the high rate of false detection,the bad effect of water-saving,etc.The system uses main water injection control technology and weighted control auxiliary injection to shorten the lag time flushing;the flush mechanism based on 3-minute detection cycle can judge peak period,low peak period and no-man period;the improved infrared monitoring technology reduced the rate of false to 0.2%.Test results show that the performances of the system are in line with the design specifications,and the water-saving rate is improved to 88%.
