Research on RFID anti-collision hybrid algorithm based on discrete processing by Ping LI, Li-min SUN, Jia-ying WU, Qing FANG, Jin-yang XIE, Bo-xiang ZHOU

“…A kind of binary tree search algorithms have distinct application limitations such as high number of requests in case that a fairly large number of tags are available.A hybrid anti-collision algorithm was proposed,combining binary tree search with discrete processing.Theoretic analysis show that,different from available schemes,the algorithm essentially performs binary tree search not on a single tag,but on models which identify the property of discrete procession.The proposed algorithm fully takes the time of request into account,as well as power consumption and throughput of the system.Simulation result verifies that the algorithm achieves much better performances such as the time of request and throughput than the previous algorithms.…”

High-precision indoor fast positioning algorithm based on carrier phase by Shaoshuai FAN, Zhiqiang RONG, Hui TIAN, Lihua LI

“…In order to improve the positioning accuracy and the speed of position solution in indoor wireless environment, a high-precision indoor fast positioning algorithm based on carrier phase was proposed.By introducing the reference terminal, the influence of clock error between devices on the accuracy of the positioning algorithm was completely eliminated by using the double difference between the carrier phase measurements of the terminal to be positioned and the reference terminal.Taking advantage of the invariability of integer ambiguity during the phase-locked loop lock-off, an iterative integer ambiguity resolution algorithm based on multi-time point measurement data was designed, and the fast integer ambiguity resolution was realized.After the integer ambiguity was solved, the terminal to be located could be located with high precision by using accurate carrier phase difference measurement.The simulation results show that the positioning algorithm proposed can completely overcome the influence of clock error on positioning performance, and can achieve centimeter-level positioning accuracy at very few sampling time points.…”

Crack Recognition Algorithm Integrating Attention Mechanism and Region Growth Method by LING Xiaokang, ZHAN Jie, MA Jianfei

“…To optimize traditional crack identification methods,improve the robustness and accuracy of the crack identification method,and realize automatic crack identification,this paper proposes a crack recognition algorithm integrating attention mechanism and region growth.It establishes dynamic thresholds and obtains the crack results under different thresholds by employing the region growth method.The attention mechanism is introduced to assign different weight coefficients to each pixel of the image according to the crack identification under dynamic thresholds for more accurate crack recognition results.Finally,the characteristic information of cracks is determined by the length of the crack skeleton and the area occupied by the crack region (length and average width of the crack).Through verifying field crack images,the results show that the crack characteristic information identified by the crack identification method integrating attention mechanism and region growth is basically consistent with the actual crack characteristics.The method features strong robustness and identification accuracy,which provides support for engineering health monitoring.…”
