The invention discloses an orthogonal multi-sub-scheduling method in a Clos switching network based on cell, which mainly solves the problem of influence on time delay performance of a system caused by increment of switching network scale in the prior art. The specific steps of the orthogonal multi-sub-scheduling method include the steps: 1 determining system parameter; 2 dividing and matching sub-procedures; 3 sending link matching requirements; 4 performing orthogonal routing of a sub-scheduler; 5 matching a link; 6 returning matching results; 7 completing all matching sub-procedures; and 8 transmitting the cell. The orthogonal multi-sub-scheduling method improves scheduling effectiveness and inter-stage link utilization rate through circular orthogonal scheduling of a plurality of sub-schedulers, thereby eliminating the influence on the time delay performance of the system caused by the increment of the switching network scale.

The invention relates to an automatic simple cascading camera chain monitoring method and system. The system is formed by serially connecting a plurality of measuring units, wherein each measuring unit consists of a camera and a cooperation mark which is fixedly connected with the camera. A measuring unit is arranged at each position to be measured in the region along the line, each settlement to-be-measured point is connected with a plurality of settlement known control points, the camera is required to simultaneously photograph two cooperation marks on the left side or the right side in the measuring process, and the settling volume of each mark and pitch angle of each camera can be directly calculated by virtue of the fixed connection constraint of the camera and the mark in each measuring unit and the geometric constraint relation of each homonymous mark imaging of adjacent cameras. According to the method, one camera only needs to be fixedly connected with single mark point and the relation between the camera and the mark point does not need to be calibrated, thereby avoiding the complicated operation for precisely determining the relative relation among multiple cameras and between the cameras and the fixedly connected multiple control points. The method can be used for automatically monitoring the settlement of roadbeds, bridges and the like and has important theoretical research significance and wide application prospect.
