Fault arc detection system based on cloud network

The invention discloses a fault arc detection system based on a cloud network. The fault arc detection system comprises a repeater, a local server and a cloud server, wherein the repeater is electrically connected with multiple arc detectors and is used for acquiring and transmitting state data of the multiple arc detectors, the state data comprises an alarm signal for arc generation, the local server is electrically connected with the repeater and is used for receiving the state data and carrying out address marking and code processing for the state data of each arc detector, each arc detector corresponding to the state data is identified, the processed state data is transmitted outwards by the local server, and the cloud server is electrically connected with the local server and is used for receiving and storing the processed state data. Through the fault arc detection system, unified management and processing for the arc detectors is realized, effective bases are provided for subsequent data analysis, timely background discovery and replacement for the damaged arc detector can be realized, and electricity safety is guaranteed for users.
