Abstract: Disclosed in the present invention is a health state assessment method for equipment based on a knowledge graph attention network, includes: steps: 1) constructing a graph data model which can comprehensively reflect change of a health state of the equipment by deeply integrating association relationships of equipment components, monitoring data dependence relationships and priori information, etc. by means of a knowledge graph and by combining with domain priori knowledge; 2) extracting feature information of the health state knowledge graph by using a graph attention network, and obtaining a target node vector representation which accurately reflects the health state of the equipment by means of learning; and 3) making a health state representation vector of the equipment pass through a fully connected layer to obtain a health state classification prediction probability, and performing training to reducing a loss value relative to a true label, thereby obtaining a health state assessment result.

Abstract: An electric boiler device based on utilization of residual energy of an elevator includes a heat storage module, an electric heating module and a control module. A heat storage water tank of the heat storage module is replenished with water from a tap water pipe network, and a preheating unit of the heat storage module converts the residual energy of the elevator into heat energy of the heat storage water tank by using an energy consumption resistor. The control module replenishes a heating water tank with water by delivering preheated water to the electric heating module according to a water level of the heating water tank, and controls a heating unit of the electric heat module to heat the heating water tank according to a user-set temperature, and heated hot water is provided through a user water supply pipe network.
