PSafetyLink is an independent intellectual property, high security level security isolation system used to solve security protection issues when industrial control systems access information networks (external networks), providing security guarantees for the connection between control networks and management information networks.
PSafetyLink has been widely applied in many large petroleum, petrochemical, natural gas, metallurgical, and municipal enterprises, such as the MES system of PetroChina Daqing Petrochemical, the MES system of PetroChina Daqing Refining and Chemical, the production command system of PetroChina Kunlun Gas, the MES transformation of Urumqi Petrochemical, the production scheduling network of Sinopec Shengli Oilfield Thermal Power Supply Center, and the energy management system of Kunming Iron and Steel. It can be widely applied in chemical, steel, non-ferrous, power generation, power grid, urban gas, machinery, environmental monitoring, urban water supply, heating, water conservancy hubs, tunnels, ports, railways, urban rail transit, and other industrial control system network boundaries closely related to national infrastructure and people's livelihood.
PSafetyLink adopts a "2+1" physical structure, consisting of two independent host systems internally. Each host system has an independent computing unit and storage unit, and runs independently on the operating system customized by Power Control Huakang. The host system on one end serves as the control end, used to connect to the control network; The host system on the other end is the information end, used to connect to the information network. Both end hosts use high-performance embedded hardware, and each motherboard has multiple Ethernet interfaces to connect the two isolated networks. The two end hosts are connected through isolation devices.
