Research on optimization of indoor positioning batch ranging system based on DS-TWR algorithm
Published 2022-01-01“…Aiming at the current problems of the ultra wide band (UWB) indoor positioning system based on the double sided two-way ranging (DS-TWR) algorithm, there are more communication times and a higher conflict rate in a multi-tag environment, an improved algorithm was proposed.The Hash algorithm to hash and distribute the communication content between the tag and the anchor was used, so that the anchor could reply to multiple tags in a regular and unified manner during each ranging process, which greatly reduced the number of times the anchor sends RES (responds) data.Experimental results show that the improved algorithms’ communication times between a tag and the anchor were reduced by 15% compared with the traditional DS-TWR algorithm, which increases the time proportion of the anchor receiving state in ranging, thereby reducing the anchor receiving RNG (range) data.The collision rate of packets, the success rate of ranging has increased by 43.6%.Due to the reduction in the number of communications required in each positioning cycle and the reduction in the collision rate between data packets, a smaller channel capacity would be required, thereby increasing the label capacity of the positioning system, which has strong engineering significance.…”

A Bracket-Stiffened Two-Planar Overlapped Tubular KT-Joint for Offshore Jack-Up Fatigue Analysis
Published 2021-01-01“…As compared with the original KT-joint and KT-joint of larger brace gap, stress concentration reduction and fatigue strength enhancement at the most critical point of the proposed KT-joint are significant under both axial and in-plane bending (IPB) loads. The superiority of the proposed KT-joint is further tested with a simplified fatigue life assessment of offshore jack-up in field transit condition, when the KT-joint corresponding to the upper guide level is most critical and fatigue-sensitive. …”

Inspection method for cable assembly quality based on AR virtual-real image attention mechanism
Published 2021-09-01“…Cable assembly in spacecraft occupies a large proportion in the final assembly process, and the quality of cable assembly directly affects the working performance of the whole product.The existing augmented reality-assisted cable assembly system lacks the ability to make real-time judgment and feedback on the assembly results, and cannot identify whether the currently assembled cable meets the quality requirements.In order to solve the above problems, a cable assembly quality inspection method based on AR virtual-real image attention mechanism was proposed.Critical areas in the captured images were located and detected by constructing virtual assist models to filter redundant image information.Based on YOLOv4-Tiny image detection model, the key node location of assembled cable was judged.The overlap of the laying path was obtained based on the method of calculating the average overlap of the neighborhood, and the bending radius of the cable was derived based on the method of camera inverse projection.Finally, an augmented reality-based cable assembly quality inspection system was developed using HoloLens2.The quality inspection was performed on the four designed cable assembly cases, and the feasibility and effectiveness of the method and system were experimentally verified.…”
