The invention discloses an EPC engineering general contractor remote operation method, which comprises a remote project operation system, a data transmission network and a project command system, and is characterized in that the remote project operation system is divided into a project operation terminal and a project operation side data center which are mutually connected, and the project command system is divided into a project command side data center and a project command terminal which are mutually connected; and the project operation side data center and the project command side data center are connected by the data transmission network to perform mutual communication. Through setting the system architecture formed by the remote project operation system, the data transmission network and the project command system, an EPC company can look for project operation sub-contractors in the local area and remotely carry out each process of an EPC project, so that the operation cost is low, the project management efficiency is high, and the personal and property safety is reliable; and through setting three-layer organization and management system architecture containing a centralized decision-making layer, a distributed management layer and an operation layer, the resource control right and the field operation command right are appropriately separated, thereby being convenient for communication and cooperation.
