Broadband network fault diagnosis method, device and equipment and readable storage medium

The invention discloses a broadband network fault diagnosis method, device and equipment and a readable storage medium, and the method comprises the steps: regularly obtaining soft probe data collected by a soft probe in a first ONU, and determining an interrupt event table of an interrupt event corresponding to the first ONU based on the soft probe data; determining a traffic statistical table based on the soft probe data and traffic data of the second ONU in a first event duration corresponding to an interrupt event in an interrupt event table; and determining fault delimitation information corresponding to each interrupt event in the interrupt event table based on the interrupt event table, the traffic statistical table, the resource data corresponding to the target OLT and the OLT alarm data. According to the method, fault analysis is carried out on the interruption event by comprehensively considering the soft probe data, the resource data and the OLT alarm data in the fault delimitation process, the sin
