DS1307及在太阳能电池控制装置中的应用

DS1307 and its application in the solar battery control system

介绍了美国DALLAS公司推出的低功耗时钟芯片DS1307的结构和工作原理及其在太阳能电池控制系统中的应用。DS1307可以对年、月、日、时、分、秒进行计时,且具有闰年补偿等多种功能。太阳光线在不同的季节和不同时间其照射的方向及角度是不一样的,为了最有效地接收到太阳光,太阳能电池板必须随着季节和时间的变化而改变方向,实时钟芯片DS1307对于太阳能电池板控制系统的时间与日期的确定具有重要意义。

This paper introduce the characteristics and the working principle of the low power RTC （ real - time clock） chip DS1307 produced by DALLAS company of the US, and introduce the application of the RTC chip DS1307 in the solar battery control system. The DS1307 can time to year, month, day, hour, minute and second, and have many characteristics such as time expiation . The direction and angle of sunlight are not the same in different season and different time, in order to receive the sunlight most availably, the solar battery control system must change its direction with the change of the season and time, it is important to make certain the date and time of the solar battery control system by using the RTC chip DS1307.
