The invention discloses a two-dimensional code identity recognition based intelligent technical protection and control method for an electric control room. Identity information is pre-acquired throughan intelligent technical protection cloud system, identity information and human face information of personnel possibly accessing to the electric control room, information of the electric control room and information of electric control cabinets are pre-acquired, electric control special operation sheet applying, examining, checking and operation authorizing are preset, identity recognition and operation authorization are performed on personnel accessing to the electric control room through two-dimensional code scanning to confirm electric control room accessing operation purposes, to-be-operated electric control cabinets, routing inspection, troubleshooting and control selection are assigned, access time of operating personnel and operating records are intelligently memorized and remotely transmitted to the intelligent technical protection cloud system in case of transmission and query, an electric control room management system can be perfected, control is facilitated, and safety and stability are remarkably improved. The method can be widely applied to two-dimensional code identity recognition based intelligent technical protection and control of electric control rooms in significant electric control facilities at different industrial, agricultural and office places.
