（1）低功耗电子标签与文物微环境监测设计：

针对文物仓库中藏品长期处于无人值守状态且传统安防设备成本高存在火灾隐患的问题，设计了一款低功耗电子标签用于监测文物匣囊内部环境。电子标签采用CC1310无线MCU，内置温湿度传感器SHT30、光照传感器OPT3001和倾斜开关。标签以纽扣电池供电，通过周期性唤醒工作模式：每10分钟唤醒一次采集数据并发送，其余时间深度睡眠，平均功耗仅12微安，电池寿命可达1.5年。标签与巡检机器人之间采用433MHz无线通信，通信距离室内可达50米。当检测到温湿度超出阈值（温度>25°C或<15°C，湿度>60%）或光照剧烈变化时，标签主动发送报警信号。在文物仓库实际测试中，30个标签连续运行3个月，数据丢包率2.3%，报警响应延迟小于1秒。

（2）巡检机器人多传感器融合与电子标签数据采集：

巡检机器人基于差动轮式底盘，搭载RFID阅读器、热成像仪和六自由度机械臂。机器人在仓库内按预设路径巡航，经过文物柜时通过RFID读取电子标签ID，并利用机械臂末端的接近开关触发标签的唤醒中断，强制标签上传实时数据。同时机器人利用热成像仪扫描文物表面温度分布，与电子标签数据交叉验证。机器人的定位采用改进的Cartographer算法融合IMU和轮速计，在建图成功率上比单纯激光SLAM提高13%。在2000平方米的仓库中，机器人完成一次全仓巡检耗时45分钟，成功读取95%以上的标签。

（3）多策略人工鱼群算法与三次样条平滑的全局路径规划：

为了解决仓库环境中障碍物多、路径曲折的导航问题，提出了一种多策略改进人工鱼群算法用于全局路径规划。引入混沌映射初始化鱼群种群，提高初始解多样性；采用自适应步长和视野，步长因子从0.5动态调整到0.2；加入精英筛选策略，保留每次迭代中的最优个体。将人工鱼群算法规划出的离散路径点用三次样条插值进行平滑，满足机器人运动学约束（最大曲率0.5）。在栅格地图上测试，改进人工鱼群算法的收敛代数比标准鱼群算法减少了42%，路径长度缩短了8.7%。局部避障采用动态窗口法，将全局路径作为参考，实时调整速度指令。在仿真和实际仓库中验证了机器人能够自主导航并完成电子标签数据采集任务。
