The invention relates to an intelligent risk management and control platform and a transmission line hidden trouble management and control method. The intelligent risk management and control platformcomprises an interrelated hidden trouble input urging module, a hidden trouble treatment urging module, a hidden trouble maintenance module, a hidden trouble audit module, a hidden trouble treatment module, a control dynamic module, a hidden trouble evaluation module and a quick vacancy elimination module. The invention adopts the intelligent risk management and control technology to carry out therisk management and control of the transmission line, through hidden trouble maintenance, hidden trouble audit, hidden trouble control, hidden trouble evaluation, hidden danger elimination and otherlinks, the records of eliminating hidden dangers are not standardized, risk of loss, etc, the hidden trouble of transmission line can be precisely managed, thereby improving line inspection quality, shortening line hidden trouble elimination time, better completing localized operation and maintenance work of transmission line, reducing line hidden trouble tripping, improving power supply reliability, improving transmission line condition management level, effectively controlling transmission line inspection and hidden trouble status, enriching monitoring means and reducing work cost.
