Abstract

GPS tracking ship is an automatic equipment used to measure water-depth, which is based on the GPS navigational signals, and the system needs real-time and efficient data acquisition through serial ports. The technology of multi-thread serial communication is applied to meet the requirements of the system. In this paper, the application of multi-thread and serial communication based on Win32 API functions is introduced. Meanwhile, a new programming method is developed, considering the specific feature of the system. With the multi-thread serial communication, the program operates steadily in Windows XP system, and has a considerable practical value in application.
