An elevator group supervisory control system includes a plurality of individual car control units which individually control elevator units, a plurality of hall control units which control hall equipment including hall call buttons provided on each floor, a group supervisory control unit which processes an assignment of elevators based on hall Information transmitted from the plurality of hall control units, and a communication control unit having an independent power supply and provided for each individual car control unit, the communication control unit being connected with a corresponding individual car control unit, a corresponding hall control unit and the group supervisory control unit for data communications. The transmission paths of the communication control units and the group supervisory control unit are connected with each other through buses to constitute the elevator group supervisory control system. Thus, communications between the hall control units and the group supervisory control unit become effective even if the individual car control units are down, as a result of which it becomes unnecessary to connect the hall call buttons with the plurality of hall control units for backup purposes, thereby making it possible to simplify an arrangement of connections.
