Fault detection system and method

The invention provides a fault detection system and method, and relates to the technical field of networks. The fault detection system comprises a processor used for detecting the network state of a to-be-detected system; the optical port detection module is used for detecting the optical port state of the to-be-detected system; the power supply detection module is used for detecting the power-on state of the to-be-detected system; the Internet of Things module is connected with the processor and the cloud platform, and the Internet of Things module is used for transmitting the network state, the optical port state and the power-on state of the to-be-detected system to the cloud platform. According to the fault detection system provided by the invention, the processor, the optical port detection module, the power supply detection module and the Internet of Things module are arranged in the system, so that the to-be-detected system can be monitored and detected in real time, the fault type and the fault positi
