The invention discloses a three-end linkage management method for a power generation enterprise. The method is characterized in that the device is characterized in that the method comprises a PC terminal, a mobile terminal and a large screen terminal. The three terminals share one background database. Data generated by the three terminals in applications are all stored in the background database so as to realize information sharing and cooperative work of the three terminals, and the mobile terminal is integrated with a wireless signal transceiving module, an iris acquisition and identification module, a two-dimensional code scanning module, a recording and photographing module and a temperature measurement and vibration measurement module. According to the invention, various functions ortools required in production and operation work are integrated on the mobile terminal equipment. Meanwhile, the operation standardization management system is divided into a PC end, a mobile end and alarge screen end for application, linkage cooperation of the mobile end with the PC end and the large screen end for application is achieved in system use, and whole-process management and control ofoperation work of power generation enterprises are completed.
