The invention discloses a photoelectric connector rolling sealing plug-in connection technology under harsh environment. The technology is suitable for hot plugging of a connector under harsh environment, such as deep water and oil gas. The sealing technology overcomes defects that a rolling sealing structure of the connector normally needs to be opened or closed through a penetration key betweena socket and a plug and the exposed key is liable to be lost, and meanwhile, the sealing technology has the advantage that the structure is simpler than an eccentric wheel orbital transfer type sealing structure. The socket and the plug of the connector of such type both have two sidewalls and a relatively slidable plugging chamber distributed in the middle, at least one cylindrical sealing structure is respectively embedded at an end part of the socket and the plug, a sealing column has a transverse penetration hole, sliding shafts are located at two sides, and at least one side has a rollingshaft of different radius. A guide groove and a U-shaped groove in cooperation with the sliding shafts and the rolling shaft are respectively embedded in the sidewalls, different positions of surfaces of two sides of the U-shaped groove respectively have one segment of external convex rolling friction band used for controlling a rotation direction of a pair of the sealing columns, and consequently, on and off of the socket and the plug is realized.

The present invention relates to a state estimation data correction system and method with improved accuracy. The system includes a data correction system, a real-time database, a dynamic monitoring system, a data acquisition and monitoring control system, an electric energy acquisition system, an online monitoring system for power transmission and transformation, and a command platform and a dynamic management system; the method includes the steps of: updating the data structure of the bad data list; updating the bad data list; finding data from the associated information I; recording information I as x1, x2, x3, x4 and judging and processing; The value in the data list is returned as an accurate measurement value, and the conventional state estimation is carried out; the associated information II is searched and the data is appended to the field data of the judgment result description field of the bad data list. The invention improves the precision of state estimation and avoids the shortcoming of data failure.
