摘要
隨著通訊控制元件的成熟發展，通訊傳輸在工業自動化控制領域也得到越來越廣泛的應用。也發展出更多的通訊架構以及協定，基於成本考量以及電路簡單化的概念下，傳統的串列通訊協定，因極具有電路簡單、成本低以及簡單易用的優勢，所以廣受多數工業控制大廠使用，特別是在遠端傳輸時，為了避免了不同廠牌而有不同的連接介面，因此串列通訊架構更被廣泛的用於控制系統中。本文研究中，主要是以目前的現場總線作為研究背景，並探討其應用，然後透過實作高速串列通訊系統的方法進行驗證與比較。其中通訊介面實作部份是透過FPGA進行介面設計，並搭配資料連結的封包協定，最後經實體差動訊號進行傳送與資料交換實現其高速通訊功能。整體控制系統實作部份則是以微處理器進行程序控制，並以主從架構方式，將資料透過FPGA進行串列資料轉換，串列資料經高速通訊介面，由主控制板傳送至遠端輸出入模組，進而對外部設備進行控制。為達到研究之訴求，最後也以不同傳輸距離與通訊速度進行比對，驗證其功能及可靠性，雖然整體通訊架構已完成，但相對於應用以及產業價值，未來仍有很大空間值得去研究與改善。

Abstract
With the mature develop of communication and control components. The communication of transmission has also been more widely used in the field of industrial automation and control. Those also develop more communication architecture and protocols. Base on the concept of cost consideration and circuit simplification. The traditional protocol of serial communication, that has a simple circuit, low cost and easy used of the superiority, so well received by the majority of industrial control company. Especially in the remote transmission, in order to avoid the different brands have different connection interface. Therefore serial communications architecture is widely used in control systems. In this paper, mainly based on the fieldbus as a research background, and explore its applications, and then through the implementation of high-speed serial communication system to verify and compare. Implementation of the communication interface that design by the FPGA, and with the data link packet of the protocol. The transmission and data exchange to achieve a high-speed communication by the differential signal finally. Implementation of the communication system that is control process by the micro processor, and builds the architecture of a master and a slave, then convert serial data by the FPGA decode. The data transmit by a high speed communication interface. That also has sent data from host controller board to the remote IO module for the control of the equipments. For the request of the paper, we are to compare the speed and distance of the communication, and verify the function and reliability. Although the overall communications infrastructure has been completed, but there is still much space is worth to study and improve of the application and industrial value in future.
