The invention discloses a power transmission line icing trend time sequence prediction method and system based on multi-source data, and relates to the technical field of power system safety monitoring and disaster prevention and mitigation, and the method comprises the steps: collecting the meteorological information, line state information and geographic space information of a to-be-predicted power transmission line in real time, forming a multi-source space-time heterogeneous sequence data set, preprocessing the data set; based on the physical process of icing, extracting time sequence features, cross-modal features and spatial features in the preprocessed data set, and constructing a high-dimensional feature vector; the cross modal characteristics comprise wet bulb temperature, wind-cold index and supercooling water gas flux; and inputting the time sequence high-dimensional feature vector into a CNN-BiLSTM hybrid prediction model based on an attention mechanism, and outputting the icing thickness and the icing change trend in a future preset time step length through a multi-step rolling prediction or direct multi-output prediction mode. According to the invention, accurate, real-time and quantitative prediction of the long-time icing thickness and the change trend can be realized.

The invention relates to an apparatus for simulating one or more eco habitat conditions. The apparatus includes at least one eco capsule unit and an air inlet chamber for receiving air. The eco capsule unit includes a pressurized water driven turbine, a low-pressure vacuum chamber, a pressurized humid air chamber, where the pressurized water driven turbine is configured to receive pressurized water to propel the pressurized water driven turbine, for generating a highly humidified air-water mixture and a pressurized humid air-water vapor by creating turbulence. The vacuum chamber is configured to enable a wind chill simulation and to remove heat from water for generating a water with reduced temperature by controlling the rate of evaporation of water. The pressurized humid air chamber is configured to capture the turbulence created water-pollutant mixture, highly humidified air-water mixture and the pressurized humid air-water vapor, to be expelled or recycled via an air blower or a humid air exhaust, for removing pollutants from the air to generate purified air with a desirable temperature.

This invention relates to the field of electric heating control, specifically to a monitoring and sensing type outdoor thermal blanket and its working method. It collects airflow state data of the outdoor environment to construct an outdoor airflow field, thereby estimating the convective heat transfer characteristics of the human body under the current outdoor airflow conditions. Based on the convective heat transfer characteristics, it estimates the global heat loss distribution of the human body, thereby identifying potential hypothermia sites. It also collects spatial state data of the thermal blanket to determine the air layer distribution between the thermal blanket and the human body surface. Based on the air layer distribution, it determines the thermal resistance characteristics between the thermal blanket and potential hypothermia sites, thereby adjusting the heating state of the thermal blanket on these sites. This invention can control the thermal blanket to precisely and stably provide heat to different parts of the human body by considering the wind chill effect caused by outdoor airflow conditions and the physical contact relationship between the thermal blanket and the human body, effectively maintaining stable body temperature.
