Embodiment Construction

[0007] The helmet 1 of this invention adopts a common protective helmet, and the difference is that an infrared spotlight 7 and an infrared camera 6 are installed on its front upper part, and the infrared spotlight 7 and the infrared camera 6 are connected to the control circuit board 5, and the front lower part is a goggle part . The side of the helmet 1 is equipped with a light sensor and a manual adjustment button. The goggles are divided into three layers, which are divided into outer protective lens 2, LCD lens 3 and inner protective lens 4 from the outside to the inside. The LCD lens 3 has two functions. One is to adjust the light transmittance in the case of sufficient light. At this time, the preset parameters in the control circuit board 5 are compared with the measured parameters of the light sensor, and a fixed control voltage is output, so that the LCD lens 3 is fixed in a corresponding light-transmitting state. At this time, the transparent thin film transistor i...

Abstract

The invention relates to all-weather field operation eye protective glasses, and belongs to constructional detection equipment in electric power industries. The all-weather field operation eye protective glasses consist of a protective helmet, eye protective glasses and a control circuit board, wherein the eye protective glasses are divided into an outer protective eyeglass, a liquid crystal display (LCD) lens and an inner protective eyeglass; a backlight part of the LCD lens is provided with a transparent thin film transistor and is connected with an LCD driving circuit and a control circuit; the control circuit board is also connected with a light sensor, a manually-regulated key, an infrared reflector lamp and an infrared camera respectively; the circuits are powered by a battery in the helmet; and the inner protective eyeglass and the outer protective eyeglass are made of polycarbonate and are pressed and bonded with the LCD lens to form an integrated structure. The all-weather field operation eye protective glasses have the advantages that: light control grades are set in the control circuit, control voltage is outputted along with the intensity of light in the daytime, and the light transmittance of the LCD lens is regulated; and when external light is weakened to a certain numerical value, infrared illumination and the infrared camera are started automatically, and the LCD lens is used as an image display to exert the effect of night vision.

Description

technical field [0001] The invention belongs to construction maintenance equipment and equipment in the electric power industry. Background technique [0002] The construction and maintenance work in the electric power industry is not only carried out according to the plan under normal weather conditions, but also often encounters sudden failures. At this time, even in the dark night in the wilderness, it is necessary to rush to the site immediately and start maintenance immediately Operation. In this case, traditional lighting tools are very inconvenient. Therefore, as a common equipment for construction and maintenance personnel in the electric power industry, a kind of all-weather field work goggles just seems very necessary. It is not only necessary to be able to adjust the light during the day when the sun is strong, but also to have a certain night vision function, so as to significantly improve the work efficiency of construction workers.
