PROFIBUS, as one of the most popular fieldbuses, has been widely used in industrial production processes. In order to improve the reliability and safety of PROFIBUS, remote monitoring and diagnosis are required. This paper proposes a remote monitoring and diagnosis system based on embedded technology, which can realize the real-time monitoring, fault diagnosis and fault resolution of PROFIBUS nodes. The system hardware uses STM32F407 chip as the main controller, and communicates with PROFIBUS bus through RS485 to UART chip and SEDIVE communication chip. The system software uses FreeRTOS operating system and C++ programming language to achieve functions such as node status detection, fault diagnosis and fault resolution. Experimental results show that the system is stable and can realize real-time monitoring and fault handling of PROFIBUS node, and has certain feasibility and application value.精品文档---下载后可任意编辑Keywords: PROFIBUS bus; embedded technology; remote monitoring; diagnostic system
