The strain sensors generate the stress strain data according to the deformationof the capsule, and wireless transmission of the stress strain data can be realized through the wirelessly connected acquisition and transmitting module and the wireless receiving module so that thedeformation of the capsule can be detected in real time, the environmental adaptability is high and effective deformation detection can be performed under various environmental conditions.

Description

technical field [0001] The invention relates to a deformation detection device, in particular to a deformation detection device used for deformation detection of a capsule. Background technique [0002] When airships are in the air, due to factors such as temperature difference between day and night, the shape of the airship capsule will change continuously. Therefore, obtaining the deformation and deformation rules of the capsule is the basis for the development of flexible inflatable structures. Due to the particularity of the flexible material of the capsule, many detection methods cannot be used, and since the airship stays in the sky, the difficulty of detection is further increased. [0003] The existing deformation detection method is to arrange a plurality of marking points on the capsule, use multiple digital cameras to take pictures for image acquisition, and perform image processing on the collected image data to obtain the deformation result of the capsule.

AI Technical Summary

Problems solved by technology

First of all, this method of using a digital camera to take pictures to obtain deformation data cannot obtain the deformation of the top of the capsule, which will result in the loss of part of the deformation data, making the obtained deformation results inaccurate

Secondly, the image data obtained by taking photos generally requires a large storage space and high transmission bandwidth, which is not conducive to data downloading; in addition, digital cameras are greatly affected by external environmental factors, and cannot take clear pictures at night. In rainy, snowy or foggy weather conditions, the camera lens will be interfered to a certain extent and cannot work well

[0004] Aiming at the problems of using digital cameras to take pictures to obtain deformation data in related technologies, such as data loss, vulnerability to weather, and high requirements for image data storage and transmission, no effective solutions have been proposed so far.
