Fault detection method and device, storage medium and electronic equipment

The invention relates to a fault detection method and device, a storage medium and electronic equipment, and relates to the field of positive-pressure concentrated-phase pneumatic conveying. The method comprises the following steps: determining operation state information of the positive-pressure concentrated-phase pneumatic conveying system; the operation state information comprises the total amount of ash generated by electric field fire coal, the equivalent length of a conveying pipe section, the conveying design output, the ash-gas ratio, the conveying air mass flow, the conveying air volume flow in a standard state, the gas-ash mixing temperature of the initial section of the conveying pipe, the conveying speed of a pneumatic ash conveying pipe, the pneumatic ash conveying pipe diameter, the pressure loss and the volume of an airlock valve; the volume of the bin pump, the free air flow of the air compressor, the standard-state volume flow of the air compressor, the total air consumption of an air compres
