Embodiment Construction

[0053] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0054] The embodiment of the present invention provides a method and device for measuring the offset and torsion of the gas cabinet piston and T baffle in order to solve the problems in the prior art that the detection of the running state of the gas cabinet piston and T baffle is inaccurate or requires manual measurement. During the operation of the gas cabinet, when the piston is at the initial position, record the image of the marker captured by the camera on the piston. If the piston does not twist and shift, the position of the camera on the horizontal plane will not change, due to the marking The object is the same in the vertical direction, so the image taken by the camera is no different from the image at the initial position. I...

Abstract

The invention provides a gas tank piston offset and torsion measuring method comprising the following steps: calculating a first displacement vector of each camera in a direction perpendicular to an optical axis according to the change in images of a first marker shot by N cameras arranged on the top of a piston bracket; calculating a second displacement vector of each camera in a direction tangential to the lens caused by piston inclination; calculating a third displacement vector of each camera caused by piston offset and torsion according to the difference between the first displacement vector and the second displacement vector; and calculating the horizontal offset, the vertical offset and the torsion angle of the piston according to the third displacement vector. The invention provides methods and devices for precisely measuring the offset and torsion of the piston and the T baffle of a gas tank online. Maintenance personnel can control the operation condition of a gas tank piston remotely and in real time. The number of times that a worker goes into a gas tank for measurement is reduced, the efficiency of gas tank maintenance is improved, and the safety of maintenance work is improved.

Description

technical field [0001] The invention relates to the technical field of gas cabinet operating state detection, in particular to a method and device for on-line measurement of offset and twist of a gas cabinet piston and a T baffle. Background technique [0002] A gas cabinet is a device that can recover and store gas as a secondary energy source. The gas cabinet is mainly composed of an external fixed shell composed of side plates, bottom plates, top plates, etc., including internal movable components composed of pistons and T baffles, and connecting side plates and T baffles, T baffles and pistons. The rubber membrane between the baffles. When the gas holder is storing gas, the piston rises, and when the gas is exhausted, the piston descends. When the piston is at a lower position, the piston bracket is disengaged from the T baffle, and the piston bracket moves up and down with the piston. When the piston descends, the rubber film between the T baffle and the piston baffle...
