Conveyor-Driven Robotic Sorting: Time-Base Regulation, Image-Age Compensation, and Cross-Layer Evaluation Data

This dataset contains the experimental records, supplementary materials, analysis outputs, audit files, post-processing scripts, and provenance resources associated with the study “Traceable Conveyor Time-Base Regulation and Causality-Constrained Image-Age Compensation for Conveyor-Driven Robotic Sorting.” The study treats conveyor speed as the physical time base linking image acquisition to future robotic picking. It evaluates encoder-feedback STEP/DIR regulation with feedforward, saturation handling, anti-windup, and rate limiting, together with a causality-constrained short-window image-age correction. The evidence is organized across control, timing, reference-coordinate reconstruction, scheduler-side pick-window, and task-outcome layers. The formal dataset covers 45 physical trials arranged as G0–G4 × D1tim–D3tim × R1–R3, with a fixed membership of 50 unique tasks per trial. The package also contains separate D0tim implementation-variant records, a representative 30-min G4-D2tim run, Supplementary Fig. S1, Supplementary Tables S1–S15, machine-readable source tables, denominator and causality audits, package manifests, and SHA-256 checksums. Under the prespecified complete-case screen, all 12 closed-loop conditions passed, with nine classified as Stable and three as Usable. For G4, timing-hit rates ranged from 97.33% to 100%; contact was confirmed for all 450 formal tasks, and no task expired. Same-record replay showed that nominal-speed, moving-average, and causal corrections reduced reference-coordinate residuals relative to no correction, but the trial-level intervals did not establish superiority of the causal rule over the simpler alternatives. In the separate 30-min run, contact was confirmed for 239 of 241 timestamped tasks with no expirations. The package supports verification and regeneration of the reported post-processing, task-membership audit, timing-denominator closure, reference-coordinate reconstruction, supplementary tables, and figures from the archived records. Raw logs are treated as primary evidence and derived summaries as secondary cross-checks. The data characterize relative operating margin within the tested protocol; they do not establish absolute host–embedded clock synchronization, independent per-task physical pick-position accuracy, global controller optimality, broad PCB-type generalization, or an empirical robustness boundary.本数据集包含与研究《可溯源传送带时基调控与传送带驱动机器人分拣的因果约束图像时效补偿》（Traceable Conveyor Time-Base Regulation and Causality-Constrained Image-Age Compensation for Conveyor-Driven Robotic Sorting）相关的实验记录、补充材料、分析输出、审核文件、后处理脚本及溯源资源。 该研究将传送带速度视为连接图像采集与后续机器人拣选的物理时基。其评估了搭载前馈控制、饱和处理、抗积分饱和及速率限制功能的编码器反馈步进/方向（STEP/DIR）调控方案，同时结合了因果约束短窗口图像时效校正方法。实验证据按控制层、时序层、参考坐标重构层、调度端拣选窗口层与任务结果层进行组织。 正式数据集包含45组物理实验，编排为G0–G4 × D1tim–D3tim × R1–R3的组合形式，每组实验包含50个唯一任务。该数据包还包含独立的D0tim实现变体记录、一组代表性的30分钟G4-D2tim运行数据、补充图S1、补充表S1–S15、机器可读源数据表、分母与因果审核文件、数据包清单及SHA-256校验和。 按照预先设定的完整案例筛选标准，全部12种闭环工况均通过验证，其中9种被归类为稳定，3种被归类为可用。针对G4工况，时序命中速率介于97.33%至100%之间；全部450项正式任务均确认完成拣选接触，无任务超时情况。同记录重放实验表明：标称速度、移动平均及因果校正方案均可降低参考坐标残差，相较于无校正方案，但实验层级的区间结果并未证明因果校正规则优于其他更简单的校正方案。在单独的30分钟运行数据中，241项带时间戳的任务中有239项确认完成拣选接触，且无任务超时。 本数据包支持基于存档记录，对已报道的后处理流程、任务成员审核、时序分母闭合、参考坐标重构、补充表格与附图进行验证与重现。原始日志被视为一级证据，派生摘要则作为二级交叉验证依据。本数据集仅表征了测试协议下的相对运行裕度，并未证明绝对主机-嵌入式时钟同步性、单任务独立物理拣选位置精度、全局控制器最优性、广泛PCB类型泛化能力，或经验鲁棒性边界。
