Abstract

The invention discloses a network fault diagnosis system, and relates to the technical field of a network device. An STM32F103VET6 control chip and an STM32F407ZGT6 control chip are employed in a terminal layer. On the basis of a 485 / CAN / GPRS Ethernet communication mode and a TCP / IP reference mode, an IEC60870-5-104 protocol is embedded for data transmission, encapsulation and protocol conversion. Data is uploaded to specialist software in a station control layer. Theoretical models of various circuit breakers, load switches, transformers are embedded in the software. A corresponding intelligent fault diagnosis algorithm is selected based on various theoretical models, thereby carrying out visual display of filed information of a power distribution network. Moreover, early warning, warning information and corresponding prevention measures are automatically provided, and therefore, the power distribution network can be monitored omni-directionally, automatically and intelligently in all weathers. The system is convenient for real-time fault monitoring and diagnosis. According to the method, a feed line interval in which a fault occurs actually, thereby facilitating subsequent maintenance.

Description

technical field [0001] The invention relates to the technical field of network appliances, in particular to a network fault diagnosis system. Background technique [0002] The existing network fault diagnosis system is inaccurate in fault diagnosis, and cannot measure the actual faulty feeder section, resulting in time-consuming later investigation, complicated operation and waste of time. Contents of the invention [0003] The object of the present invention is to provide a network fault diagnosis system aiming at the defects and deficiencies of the prior art. [0004] In order to solve the existing problems of the background technology, a network fault diagnosis system of the present invention includes a terminal layer, a protocol conversion layer, and a station control layer; IEC60870-5-104 protocol is embedded on the basis of the communication method of Ethernet / Ethernet and the TCP / IP reference model for data transmission, encapsulation and protocol conversion; then ...
