旁白:歡迎來到「電信@臺灣」展廳。你現在是怎麼跟家人、朋友聯繫的呢?LINE?Instagram?都是立即傳送,對吧?!但是在沒有電話、網路的時代,想把重要消息傳到遠方,只能靠書信、馬匹或船隻傳送,往往需要好幾天,甚至幾個月。
到了19世紀,一項改變世界的通信技術出現了—那就是「電報」。電報利用電流的變化,在線路中傳送訊號。1877年,從安平、臺南到旗津,臺灣第一條電報線路誕生,臺灣的電信發展也從此展開。人們開始能在短時間內傳遞遠距離消息,對政府管理、商業活動和社會交流,帶來重大的改變。
那麼,電報是怎麼運作的呢?發報員透過發報機上的按鍵,控制電流的通與斷,短按是「滴」,長按是「答」,放開時則不通電,也沒有聲音。這些有節奏的聲音,就是「摩斯電碼」。訊號傳到收報端後,會在紙上留下點、線與空格,透過排列組合對應不同的英文字母與數字,就能轉換成文字訊息了。
現在,你也可以親自試試看。到左側展區按下電鍵,敲出一段簡單的電碼,感受一百多年前,人們如何用一段節奏,把訊息傳向遠方。
Narrator: Welcome to the Telecom@Taiwan exhibition hall. How do you stay in touch with friends and family these days? LINE? Instagram? It's all instant messaging, right?! But in an era without telephone or internet, if you wanted to send a message far away, you could only do so by letter, horse, or ship. That used to take days or even months.
By the 19th century, a communication technology appeared that changed the world—"electrical telegraphy." Electrical telegraphy uses changes in electric current to send signals through a wire. In 1877, Taiwan's first telegraph route was born between Anping, Tainan, and Qijin. This also marked the start of the development of telecommunication in Taiwan. People began to transmit messages over long distances in a short time, which led to major changes in government administration, commercial activity, and social interaction.
So, how does electrical telegraphy work? The telegraph operator uses the button on the telegraph to control the electric current, allowing it to pass through or not. A short press is a "dit" and a long press is a "dah." When the button is released, no electric current passes through, and it doesn't make a sound either. These rhythmic sounds are called "Morse code." When the signal reaches the receiving end, dots, dashes, and spaces are left on paper. By arranging and combining this code into the different corresponding English letters and numbers, it can be turned into a text message.
Now, you can try it yourself. Press the button on the left side of the exhibition space to tap out a simple code and experience how people over a hundred years ago used rhythm to send messages far away.
