介绍了一种日常参数智能控制器的研制及研制过程中的几个重要问题的解决方法。特别是用于城市照明及美化城市的彩灯的开、关时间智能控制方面，给出了依据当地绝对时间、经度、纬度进行昼夜时间计算的方法，使之在不接光电传感器情况下可跟踪季节的昼夜变化。控制系统采用８９Ｃ２０５１单片机，配有时钟日历芯片ＤＳ１２８８７，系统体积小、功能强、可靠性高。 This paper introduces a solution to some important problems in the development and daily development of intelligent parameter controller. Especially for the urban lighting and beautification of the city lights on and off the intelligent control of time, given according to the local absolute time, longitude and latitude to calculate the time of day and night, so that without the case of optical sensors can be tracked The diurnal changes of the season. The control system uses 89C2051 single chip microcomputer, with the clock calendar chip DS12887, the system is small, powerful, high reliability.
