為了通過串口發送命令以控制紅外相機，使其完成非均勻性校正、壞點替換以及積分時間、幀頻的參數設置等各項任務，對控制軟件的設計方法進行了研究。在Visual C++ 6.0 平臺下，通過調用PComm 函數完成對串口的初始化、打開、關閉等操作；通過構造命令處理函數庫，完成對串口的數據讀寫和顯示。設計的軟件經實驗裝置調試、檢驗，可靠性強，可以滿足設備實時控制的要求。

Abstract：A design method for the control software for serial port communication between the personal computer and the infrared camera is presented, in order to make the infrared camera complete its mission of nonuniformity correction, bad pixel replacement, parameters settings of the integration time and the frame frequency and so on. The initialization, open and close of the serial port can be completed by calling the PComm function, and the read-write and display of the data from the serial port can be completed by calling the function from the command processing function library which has been created with Visual C++ 6.0.The reliability of the software designed is good, and the software can satisfy the real time control requirements of the equipment by debugging and testing.
Key words: Serial port; Infrared camera; Visual C++; PComm function
