Abstract: Methods, apparatuses, systems, computer readable media, and a computer product for detecting a gas leak of a gas tank. In a method, at least one inside temperature is determined for the gas tank based on a plurality of outside temperatures that are collected outside the gas tank, the at least one inside temperature being estimated for at least one inside position within the gas tank during an operation of the gas tank. A gas pressure within the gas tank under a standard temperature is obtained based on the at least one inside temperature. The gas leak of the gas tank is detected based on the gas pressure.

Abstract: Methods and devices for monitoring and maintaining a health state of an electrical device. The methods can include obtaining a first operation state of the electrical device; rendering a holographic image of the electrical device and a first health state of the electrical device indicated by the first operation state by using a mixed reality device; detecting an action of a first user by using the mixed reality device; in response to that an operation performed by the first user on the electrical device has been detected, performing the operation on an image model of the electrical device in the holographic image to obtain a second operation state after the electrical device is operated; and updating the first health state to a second health state indicated by the second operation state.

Abstract: A method and an apparatus for training a model for predicting a temperature rise of a heating element in a switchgear. The method includes obtaining a model for predicting the temperature rise. The method also includes obtaining n+1 sets of physical quantities in relation to the heating element, each set of physical quantities being collected at a corresponding one of n+1 time points spaced apart from each other by a time step in a normal operation state of the heating element, each set of physical quantities comprising a current and an actual temperature of the heating element and an ambient temperature. The method includes converting the actual temperature in each set of physical quantities into an actual temperature rise based on the corresponding ambient temperature; and training the model with the current, the actual temperature rise and the ambient temperature to determine the several parameters.
