(上接《智能建筑》2014年第9期)7第15章时钟系统7.1系统介绍时钟系统是由标准时间源,石英谐振母钟、子钟及其他时控设备组成。采用自守时和时间跟踪的方式,使石英谐振器母钟、子钟以及输出的其他时间信号与标准时间源保持一致,实现时间的同步。随着现代科技不断发展,时钟系统技术应用将更为广泛,时钟系统的应用范围广阔,已在公共广场、飞机场、火车站、轻轨、港口码头、工厂、金融机构、学校、智能楼宇等场所都得到
(上 接 Intelligent Building, Issue 9, 2014) 7 Chapter 15 The Clock System 7.1 System Introduction The clock system consists of a standard time source, a quartz resonator master clock, a clock, and other time-controlled devices. Using self-time and time tracking approach, the quartz resonator master clock, clock and other output time signal and the standard time source to achieve the same time. With the continuous development of modern science and technology, the application of clock system technology will be more extensive. The clock system has a wide range of applications and has been widely used in places such as public squares, airports, railway stations, light railways, port terminals, factories, financial institutions, schools, Have got it
