中文摘要 | 本文的目的是針對織布廠無線電監系統之資料傳輸而設計,由於 數位信號無法直接傳送,故將輸入之數位訊號,利用調變方式,轉換成 頻率信號,以此信號去控制機臺,達到藉頻率來傳送資料的目的。機臺 回傳之頻率信號經解調電路解調後,再利用類比/數位轉換器轉換成數 位信號,經由8255介面輸入電腦,再由判讀程式判讀,此編碼器可做四 位元的並列資料傳輸,其速度較一般的串列傳輸方式快,並可將傳輸簡 化。資料經此技術處理後的優點有:1.防止雜訊干擾。2.提高傳輸之效 率。3.多通道傳輸之功能。同時本研究中利用電力線調變方式,進行資 料之傳輸,此技術也可應用在其他資料系統之傳輸上作為高速率的數據 傳輸使用。 |
英文摘要 | The aim of this paper is to design an Encode/Decode device for the transmissions of computer Monitoring system in weaving mill. The digital signals can't transmit on wire directly, so therefore, the signals shall modulated and converted into the frequent signals. With it, the signals can be used to control the opening functions of a weanving machine. The signals, Which are responed from the weaving machine, are demodulated. They will be converted by using analog to digital converter into the digital signals and linally they will be send to the 8255 interface bus of the computer for advance data processing. With the computer software, a program was designed to judge and reduce the signals become inital. The decorder can transmit 4 bits data once in parallel simultaneously. The advantages of this device are not only shorten the transmission time, where, the transmit is faster than the same way with series method but also simplify the layout of transimit wire. The main contributions of this device are:1.Prohibit the interference of noise. 2. Increase the transmit rate. 3.Able to proceed the transition with multichanel. This technigues can also be used in other communication system for a high speed data transmission usage. |
