Abstract: Control system for navigation and reduction operation including a master control apparatus having a host and an optical tracker; a tracing apparatus including a target body tracer arranged on a target body; the optical tracker is configured to obtain a geometric feature of the target body tracer in an actual working space; the host is configured to convert a preliminary image into an intermediate image by matching the preliminary image with the intermediate image, and to convert the preliminary image into the actual working space according to a geometric feature of the target body tracer in the intermediate image and the geometric feature of the target body tracer in the actual working space, to obtain a target pose of the operation apparatus in the actual working space, and to control an operation apparatus to move to the target pose for reduction. A method for navigation and reduction operation is provided.

Abstract: Disclosed is a method of implementing a redundant network. Ring network nodes in an initial state are set as master stations, ring ports are set in a half-blocked state, a master station election notification message is broadcast to the ring ports within a preset time interval, the nodes receive the master station election notification message, a node quality comparison vector is compared with node quality comparison vectors of the nodes to elect a master and standby stations, one of the ring ports is in the half-blocked state, the other ring ports are in a forwarding state, the master station broadcasts the master station election notification message to the ring ports, the standby master station stops sending the master station election notification message, the ring ports are in the forwarding state, and the message sent by the master station is received.
