The method comprises the following steps: recording a mapping relation between a line network signal action bit and a top layer signal bit in a forced assignment statement in a first relation database, and selecting a target line network signal; recording a mapping relation between a top-layer signal bit and a corresponding compulsory assignment module identifier list in a second relation database, and then dynamically recording a mapping relation between a top-layer signal and a compulsory assignment module in a dynamic database; and updating the dynamic database and modifying the state of the enforced assignment module which is currently in an active state in the corresponding enforced assignment module identification list into a state which needs to be confirmed, and when the assignment content of the target line network signal is changed, confirming and updating the state of the involved enforced assignment module in combination with the second relational database. And executing the forced assignment updating operation which really needs to be executed. The system performance is improved.

This application discloses a method and system for synchronous measurement of three-dimensional displacement field of transparent soil based on binocular vision. This application improves upon current displacement field measurements that require full-field matching. First, a local comparison window is defined for the current speckle grid. The similarity of the speckle grid in the local comparison window at time t+1 is compared with the current speckle grid to determine its position. Then, the displacement vector of the speckle grid can be determined by directly assigning the vectors of other speckle grids with similar speckle density within the local comparison window to this displacement vector. Thus, the displacement vectors of multiple speckle grids can be obtained after calculating the displacement vector of only one speckle grid, effectively reducing the amount of data processing.
