in view of the improvement of the safety management of power supply in the petrochemical industry, and the gradual establishment of management modes such as integrated control and unattended management, in order to adapt to the changes extended from the regional, centralized control and real-time modes, an integrated control and online anti-misoperation system came into being. an anti-misoperation management system for the whole process from issuance and breakdown of dispatching instructions to operation execution was established. the system centers on a control anti-misoperation server, adopts lan optical fiber communication and short-range wireless communication technologies, integrates the misoperation prevention of the dispatching seat, the misoperation prevention of the monitoring seat and the misoperation prevention of the site into the same anti-misoperation platform, manages the data on the sides of centralized control centers and slave stations in a unified way to prevent information islands, operates in a standard way according to the process procedure “drafting an instruction - review - pre-instruction - execution - reporting” and provides a safety guarantee for dispatching instructions, remote control and field operation. according to the architectural design of the multilayer control anti-misoperation system, it mainly comprises a psm72-dk control center online anti-misoperation system, a psm72-jkd centralized control center online anti-misoperation system, a substation (slave station) fy3000-csa control slave station fail-safe upgrading system and an fy3000-csb control slave station integrated online anti-misoperation system.
