Sensing structure and sensing method capable of detecting displacement

The invention relates to the technique of displacement sensing, in particular, to a sensing structure and a sensing method capable of detecting displacement, in particular for sensing between two positions.

Pressing to detect the offset between two structures or parts in a structure or system is an important means of preventing structural or system defects, such as a pipeline or piping system that uses a majority of the tubes to transport fluids. The transportation system can be found in general buildings, company lines, schools or factories, etc., which can be used to transport people's livelihood necessities (such as tap water) or industrial materials (such as oil, natural gas, sewage, chemical substances). It is already an indispensable part of people's lives, and pipelines need to be inspected regularly to prevent leakage of the materials being transported and to avoid danger and harm.

There are many methods for detecting pipelines in the current technology to discriminate whether the pipeline leaks. In addition to the conventional visual inspection, the pressure of the fluid in the tube body is detected at different positions of the pipeline. When the fluid pressure in the pipe body is low, the pipe body may represent A situation in which a leak occurs. Or to detect whether the pipeline is broken by an ultrasonic detecting device along the pipeline. Or set a strain gauge on the circumference of the pipe body to detect whether the pipe body is excessively deflected and prevent leakage.

However, the detection method is used to detect whether there is any defect in the wall of the pipe body, and it is impossible to detect whether there is a deviation between the joints between the two pipes, and it is difficult to judge two. Whether the connection position of the pipe body is offset.

It is conventional to detect whether the connection between the two tubes is deviated or offset by a non-contact method for emitting visible light. A movable visible light emitter and a light receiver are respectively mounted on the two connected tubes, and the visible light is emitted to and displayed on the light receiver, and the visible light falls. Point to determine whether there is a deviation in the joint of the two tubes. To detect the connection condition of the two tubes at different positions, the light emitter and the light receiver are erected on the two tubes to be tested.

The above-mentioned non-contact detection method is only a simple detection method, and the detection result is not accurate, and it is impossible to accurately determine whether the connection portion between the two tubes is well connected, and it is necessary to improve.

In addition, the building structure of a building such as a house or a bridge today is constructed by using a plurality of steel beams or beams to make it durable for a long period of use and to withstand the stability of various impacts. It ensures the safety of the building.

However, Taiwan is located in a seismic belt with frequent plate movements. On average, thousands of earthquakes of varying sizes occur every year, causing deviations or deviations in the steel beam structure of buildings, and buildings in important facilities, such as nuclear power generation. In order to ensure the high safety of the structure of the factory, dam or ammunition storage, the position and spacing of the steel beams are subject to subtle and precise calculations, even if only slightly offset, it will cause damage to the building structure. If it is not handled quickly, the slight offset may form a misplaced position that is difficult to ignore. Not only is the durability and stability of the building greatly reduced, but it is also difficult to withstand the impact of the next large earthquake, causing unpredictable hazards.

However, since the steel beam structure is the backbone of the building, it is buried in a very hidden space, and the maintenance personnel cannot check frequently. Moreover, if the steel beam structure is only slightly offset, it is impossible to visually Determine whether the steel beam structure is biased Move, you must use professional equipment to check, so that the inspection time increases, reducing the efficiency of inspection. Thus, how to quickly and accurately detect whether the steel beam structure is offset or not becomes an important and problem to be solved.
