The invention provides an IEC 104 safety remote control method based on a discrete addressing technique. The method includes the following steps of based on conventional remote control remote regulation mechanisms of an IEC104 communication protocol, changing an addressing mode of an information object address of remote control remote regulation amount from an existing continuous addressing mode to a discrete addressing mode; designing a specific mapping relation, so that scheduling numbers of primary equipment target objects corresponding to all the remote control remote regulation amount are mapped to information object addresses which are not repeated; checking and authenticating the information object address designated by remote control remote regulation commands through a station so that a mistaken remote control intention of a main station can be intercepted. The method solves the problems that in IEC104 telecontrol communication, mistaken remote control is caused due to the fact that the station cannot identify mislocation of the information object addresses, guarantees safety and reliability of the remote control remote regulation process, and accordingly improves operation safety of a power grid.
