中文摘要 | 商用調頻廣播已存在多時,其所提供的服務項目主要為聲音節目的傳送。隨著時代的演進,人們對於資訊的需求日增,各項新式的傳送技不斷的發明以提供傳送的要求,對於現行商用調頻廣播系統的改善,也是努力的方向之一。其主要的目標是將數據經由現有的廣播系統傳送出去並與現有系統結合,由此獲得相得益彰的效果。本文以數位化副載波系統為基礎設計了一套時間信號接收與校正系統。它單晶片微電腦89C51與接收數位化副載波信號用的晶片組合而成。經由接收頻電臺所發射的調頻副載波信號得以每分鐘校正接收機的內部時鐘。 |
英文摘要 | Commercial Frequency Modulation (FM) broadcasting has already existed for many years and its main function is provide voice service. With the rapid progress in digital technologies, people demand more information in daily life. Various kinds of technologies are invented to satisfy this need. Creating the digital signal transmission capability in the commercial FM broadcasting system is one of these technologies and becomes an interested research recently. In this paper, we present a time signal receiving system using the radio data system (RDS) which using FM sub-carrier transmits digital signals. This time signal receiving system is composed with 895CA microprocessor and several chips. It can receives the time signal which was transmitted form an FM station and calibrates the time counting in the receiver circuits every minutes. |
