Embodiment Construction
[0049] 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.
[0050]The embodiments of the present invention provide a method and device for measuring the offset and torsion of the gas holder piston in order to solve the problems in the prior art that the detection of the running state of the gas holder piston 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. If the piston is shifted, twis...

The invention provides an offset and torsion measuring method and device for a gas chamber piston. The method includes calculating a first displacement vector of each camera according to image change, which is recorded by the cameras arranged on the top of a piston support, of a plurality of markers exactly opposite to the cameras; calculating a second displacement vector of each camera caused by piston inclination; calculating a third displacement vector of each camera caused by piston offset and torsion according to the difference of the first displacement vector and the second displacement vector; calculating and obtaining the horizontal direction offset, the vertical direction offset and the torsion angle according to the third displacement vector. The invention provides the method and device for measuring the offset and torsion of the gas chamber piston precisely in an online manner. Maintenance workers can know the operation condition of the gas chamber piston remotely in real time. Therefore, in-cabinet manual measurement frequency can be reduced, the maintenance efficiency of the gas chamber is improved and the maintenance safety can be improved.
Description
technical field [0001] The invention relates to the technical field of gas cabinet operation state detection, in particular to an on-line measurement method and device for offset and twist of a gas cabinet piston. 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 will fold. When ...
