The invention provides an on-site sensing intelligent helmet, on-site sensing method, device and storage medium. The helmet is provided with an infrared imager and intelligent glasses which are in communication connection, the infrared imager senses electrical equipment to obtain infrared sensing data and generates infrared imaging and temperature field data of the electrical equipment, the intelligent glasses generate corresponding visible light and infrared superposed image and temperature field image according to the infrared imaging and temperature field data, obtain associated electrical equipment associated information directing at an original image of the electrical equipment from a monitoring background in communication connection, and combine the electrical equipment associated information to the original image to generate an augmented reality image of the electrical equipment, and the augmented reality image together with the infrared image and the temperature field image is displayed on the intelligent glasses. The intelligent helmet is utilized to realize tour inspection, hands of tour inspection personnel are liberated, fusion of an infrared thermal imaging function and an augmented reality function is realized, referable associated information amount of the electrical equipment is increased, and tour inspection efficiency is effectively improved.
