Abstract In order to realize the function of DTU, a design of mine-used DTU system based on UCOS-II is given. The DTU uses the STM32F103VE as processor, and the real-time operating system (UCOS-II ) is transplanted to this CPU. The design scheme of the hardware and software of the system is introduced in this paper. The software is simplified, and the maintainability of the software is increased by using the real-time operating system. Through the debugging, the DTU system can meet the needs of the enterprises.
