The invention discloses a message tracking method, system and equipment, and the method comprises the steps: obtaining a network connection state between a network adapter of an upper computer and a network port of a lower computer; if the network connection state between the network adapter of the upper computer and the network port of the lower computer is a disconnection state, pinging the IP address of the network adapter of the upper computer and the IP address of the disconnected network port of the lower computer; if successful, capturing a network communication message between the network adapter of the upper computer and the disconnected network port of the lower computer to obtain a message tracking file, and storing the message tracking file to a preset path; The method captures a network communication message between a network adapter of an upper computer and a network port of a lower computer so as to realize the message interaction between the upper computer and the lower computer on a link layer, and obtains information interaction between the upper computer and the lower computer after instant disconnection, so that disconnection reasons between the lower computer and the upper computer are accurately positioned.
Description
technical field [0001] The invention belongs to the technical field of distributed control systems, and relates to the processing of data transmitted by the distributed control system, in particular to a message tracking method, system and equipment. Background technique [0002] Distributed Control System (DCS) is a new type of control equipment that uses computer technology to conduct centralized monitoring, operation, management and decentralized control of industrial production processes. It is widely used in industrial production fields such as electric power; as the scale of power systems increases The larger the structure, the more complex the structure, and the management of power equipment is becoming more and more important. [0003] In a power plant, the upper computer of the distributed control system communicates with the lower computer through various protocols; during the operation of the distributed control system, when the upper computer and the lower comput...
