The invention discloses a power emergency converged communication dispatching command system which comprises one or more dispatching hosts, and each dispatching host is connected with a dispatching desk; each dispatching host comprises a motherboard, a 1+1 redundancy-control main control unit and a 1+1 redundancy-control secondary power supply and various specialized function interfaces; and the specialized function interfaces include a user interface, a loop interface, a 2/4-line EM interface and a 2M relay interface, as well as a sound recording interface, a VOIP (Voice over IP) interface, a satellite phone interface, a GSM (global system for mobile communications) interface, a CDMA (code division multiple access) interface, a wireless cluster interface and a wireless intercom interface which are newly added. According to the invention, the voice communication among different communication systems such as C/G-network mobile phones, digital cluster terminals, simulation cluster terminals, conventional radio stations, intercom systems, fixed-line telephones, SIP (session initiation protocol) phones, satellite phones, short-wave radio stations, and the like is realized. The power emergency converged communication dispatching command system disclosed by the invention is the application of a converged communication technology in power emergency systems, and solves the problem of ensuring that a comprehensive response is made in the shortest possible time after power system emergencies occur.
