Intelligent switching method for positioning base station required by UWB positioning system in two-dimensional and three-dimensional positioning scenes

The invention belongs to the technical field of UWB positioning. The invention specifically relates to an intelligent switching method for positioning base stations required by a UWB positioning system in two-dimensional and three-dimensional positioning scenes. The method comprises the following steps: S1, giving different positioning base station receiving signal angles [theta]i, j (i = 1, 2, 3,and the like, N, j = 1, 2, 3, and the like, M) to different positioning base stations according to positioning node receiving angles, N being the number of layers where the positioning base stationsare located, and M being the number of the base stations; and S2, initially setting a two-dimensional positioning scene, and judging that the positioning tag is located between the several layers of base stations according to positive and negative conditions of [theta]i, j values. The required positioning base station is intelligently switched by using the positive and negative value change of thesignal receiving angle of the positioning tag and the positioning base station, so that the link of the positioning tag, which is irrelevant to the current positioning, is reduced, the utilization rate of the base station is optimized, and the average power consumption of the whole positioning system is reduced.

Virtual machine management method and system

The embodiment of the invention provides a virtual machine management method and system. The method comprises the following steps: firstly, a management client in a virtual machine manager sends a virtual machine management request through a second direct connection port, and a kernel server receives the virtual machine management request through a first direct connection port; then the kernel server manages the virtual machine based on the virtual machine management request to generate a virtual machine management result; and the kernel server sends the virtual machine management result to the management client through the first direct connection port. Based on the first direct connection port and the second direct connection port, an efficient management channel is provided; according to the method, the kernel server in the user mode is moved into the kernel of the client to form the kernel server in the kernel mode, so that the link between the management client and the kernel of the client is shortened, the management link of the virtual machine is shortened, the stability of the kernel of the client is improved, and privileged operation can be performed based on the kernel mode of the kernel server; and the management efficiency of the virtual machine is improved.

Ultra-narrow linewidth integrated fiber laser based on distributed external feedback

PendingCN114530749ASolve the problem that it is difficult to achieve extreme compression of line widthSimple structureActive medium shape and constructionLine widthMiniaturization
The invention provides an ultra-narrow linewidth integrated fiber laser based on distributed external feedback, which comprises a fiber laser main cavity and a distributed external feedback structure, and is characterized in that the fiber laser main cavity generates main cavity laser under the excitation of a pumping source and provides the main cavity laser to the distributed external feedback structure; the distributed external feedback structure generates a distributed feedback signal according to the main cavity laser and reversely transmits the distributed feedback signal back to the optical fiber laser main cavity; and the distributed feedback signal carries out extreme regulation and control on the performance parameters of the main cavity laser, so that the main cavity of the fiber laser outputs single-longitudinal-mode ultra-narrow linewidth laser. The output of the single longitudinal mode laser and the compression of the line width do not depend on cavity length adjustment any more, performance parameters of the main cavity laser are regulated and controlled through distributed feedback signals, the output of the single longitudinal mode laser can be achieved, the line width can be extremely compressed, and the laser is simple in structure and low in cost. And the integrated miniaturization development of the laser is facilitated.
