| 摘 要： | DS1302是美国Dallas公司生产的高性能、低功耗时钟集成电路,本研究将其应用于温室CO2增施控制器中,不仅可以为控制器提供定时功能,还利用了其内部RAM保存重要用户数据。当系统掉电时,DS1302自动采用备用电源工作,维持时钟运行,并保护用户数据,系统重新上电工作后可以从DS1302中恢复数据。这种用法极大地提高了系统的实用性和安全性,增强了系统的整体性能。

| Abstract: | DS1302 is a kind of integrated circuit with high performance and low power consumption which is made in America by Dallas company.In our study ds1302 was used in a CO2 enrichment controller used to release CO2 to greenhouse.DS1302 not only provide date and time for the system but also save important user date.When electric power was shut off DS1302 could go on working with backup power supply.User data could be saved in RAM of DS1302 and after electric power was recovered those data could be restored to MCU.With this way the system achieved high practicability and safety and was improved. |
