面向地下结构的火灾病害标记数据

该数据存储了温度传感器所记录的隧道从火势开始到结束全阶段的温度数据，每个传感器所记录的温度数据是一个数值型序列，表示不同采样时间点的温度，是用于针对火灾性态辨识模型的测评数据，时间顺序记录了病害发生及前后一定时间段内的传感器特征及其对应的值，每个数值代表传感器测量的监测点温度。其中产生火灾的时间段被标记为红色，是提取病害信息样本的依据。文件格式为xlsx，每一列对应一个传感器所记录的全时段的温度数据，每一行表示不同传感器在同一时刻的温度数据。文件第一行记录了各个传感器的相对位置，最左边的一列记录了相对时间信息。经统计，时间跨度为3911个单位时间，空间范围由57个传感器覆盖。数据量为8.52 MB。

This dataset stores temperature data recorded by temperature sensors throughout the entire lifecycle of a tunnel fire, from ignition to extinction. The temperature data recorded by each sensor is a numerical sequence representing temperatures at different sampling time points, and this dataset serves as evaluation data for fire behavior identification models. It chronologically records sensor features and their corresponding values during the period around the fire occurrence, where each numerical value represents the temperature of the monitoring point measured by the corresponding sensor. The time interval during which the fire occurred is marked in red, which is the basis for extracting fire-related feature samples. The dataset is stored in XLSX format: each column corresponds to the full-period temperature data recorded by one sensor, while each row represents the temperature readings of different sensors at the same moment. The first row of the file records the relative positions of all sensors, and the leftmost column stores relative time information. According to statistics, the time span covers 3911 time units, and the spatial scope is covered by 57 sensors. The total data size is 8.52 MB.
