Transient dataset of household appliances with Intensive switching events

This is a dataset for energy load monitoring, where we use self-developed high-frequency acquisition equipment to sample the current and voltage at the instant of startup of single appliances and aggregated appliances, with a sampling frequency of up to 51.2kHz. Data file, data to the current and voltage of a cycle (20ms) as a record for storage, each record contains the current or voltage collected during the cycle of 1024 points of the original value (Value), the collection and marking system common timestamp mark (RecvTime, the timestamp can be accurate to the milliseconds), the number of sampling points of each waveform (used to increase the frequency of the sampling later to the The current position is 1024 sampling points, Rate = 1024), sampling channel (Channel = 1 for voltage, Channel = 2 for current), room number (Home, the room number is not the real room number, but our laboratory according to the actual situation of the simulation of the home electricity environment number), microcontroller RTC time (DeviceTime, the property has no special meaning, and is only used alone for the purpose of the system. attribute has no special meaning and is only used alone to check the integrity of the data file). Marking file, each record of the file by the collection and marking system common timestamp marking (RecvTime, the timestamp can be accurate to the milliseconds), on the appliance switching event records (event, a single appliance marking format: appliance number - appliance switching; aggregated data marking format: socketx:0/1).The acquisition device is calculated to have a linearity of 99.5818% and 99.7789% for both voltage and current, which allows the acquisition device to accurately capture subtle signal changes in voltage and current.Data collection demo scenarios have been posted on http://f-lab.ncepu.edu.cn/?id=3&UrlID=0.本数据集用于电力负荷监测，我们采用自研的高频采集设备，对单台电器及聚合电器启动瞬间的电流与电压进行采样，最高采样频率可达51.2kHz。 数据文件以一个周期（20ms）内的电流、电压数据作为单条记录进行存储。每条记录包含：该周期内采集到的1024个原始采样点的电流/电压原始值（Value）、采集与标注系统共用的时间戳标记（RecvTime，该时间戳精度可达毫秒级）、每条波形的采样点数（用于后续将采样点数调整至1024个的标准格式，Rate=1024）、采样通道（Channel=1代表电压，Channel=2代表电流）、房间编号（Home，该编号并非真实房间号，而是本实验室模拟家庭用电环境时设定的编号）、单片机实时时钟（Real-Time Clock, RTC）时间（DeviceTime，该属性无特殊业务含义，仅用于单独校验数据文件的完整性）。 标注文件的每条记录均通过采集与标注系统共用的时间戳标记（RecvTime，精度可达毫秒级），用于记录电器开关事件（event：单台电器标注格式为"电器编号-电器开关状态"；聚合数据标注格式为"socketx:0/1"）。 经测算，本采集设备的电压与电流采集线性度分别为99.5818%与99.7789%，可精准捕捉电压与电流的细微信号变化。 本数据集的采集演示场景已发布于http://f-lab.ncepu.edu.cn/?id=3&UrlID=0。
