摘  要
隨著計算機技術的發展和推廣，利用串口進行數據通訊在通訊領域中占有著重要的地位。為了方便和快速的通過Internet網絡訪問串口服務器的串口，本課題把串口通信集成到Windows服務，由Windows服務完成串口通信的基本操作。文中詳細描述了串口通信服務的原理和工作流程，還列舉出了相關的核心代碼。用流程圖的方式來描述了各個模塊的邏輯實現。串口通信服務中采用安全隊列的機制來控制多線程訪問多串口。在開發中按照軟件工程的流程，從需求分析到概要設計，從詳細設計到編碼，以及最后的測試，利用軟件工程的工具管理開發代碼和文檔。此外，還開發出了客戶端來測試該服務工作是否正常。經過測試服務工作正常，能通過網絡連接到服務器完成串口的通信。最后總結了開發和設計的不足之處，程序還有待進一步完善。

The Development of Serial Communication Service
Based on VC++
Abstract
With the development and spread of computer technology, serial communication is an important part in the field of computer network communication. In order to access server's serial port more convenient and faster through the Internet, this topic put serial communication services integrated into Windows service, which completed the basic operation of serial communication services. The serial communications services and the workflow are in detail described. The core code of the services is also given. Flow chart is used to describe the handling process of the serial communications services. The services using safe queue mechanism to control multithreading visit serials. During the entire development, according to the software engineering flow, from requirements analysis to summary design, from detail design to coding, and the final test, uses the software engineering tools to management the code and documentation. In addition, I developed a client to test the service. Test results of the experiment indicate the services can work normally. In the end, summarizes the disadvantages of the design and development, and further perfection of studies is surely in need.

Key words: Serial Communication; Windows Service; Safe Queue; Multithread
