Description

Technical Field

[0001] This utility model belongs to the field of building engineering structural quality monitoring technology, and in particular relates to a front-end acquisition and transmission device for an intelligent crack monitoring system. Background Technology

[0002] In the maintenance and inspection of civil engineering, especially large infrastructure such as bridges and tunnels, monitoring surface cracks is crucial. Cracks are a significant factor affecting the structural safety of buildings. Early cracks on buildings are usually small, but over time they develop and widen. When the width of a crack exceeds a certain limit, it seriously compromises the structural safety of the building. Therefore, it is essential to monitor crack width changes in addition to detecting crack width to understand the development of cracks in the building. Currently, the most common crack detection method is manual inspection, where inspectors use instruments or direct visual observation. This method requires close contact with the crack, making it susceptible to the influence of the inspector's subjectivity, resulting in inaccurate data. It is also inefficient, time-consuming, and labor-intensive, and does not facilitate effective monitoring of crack width changes later on. With the increasing number and aging of urban infrastructure, the task of monitoring and maintaining surface cracks in buildings, bridges, roads, and other infrastructure is becoming increasingly demanding. Traditional detection methods rely on manual inspections, which are inefficient, costly, and unable to achieve real-time monitoring.

[0003] To address this, a front-end acquisition and transmission device for an intelligent crack monitoring system is proposed. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Reference Figures 1 to 3 As shown, this embodiment provides a front-end acquisition and transmission device for an intelligent crack monitoring system, including: a housing, comprising an upper shell 1 and a lower shell 2 that are interlocked; a battery and a photosensitive sensor are installed inside the upper shell 1; a transmission module and a control unit are installed inside the lower shell 2; an image acquisition hole 3 is provided at the bottom front side of the lower shell 2, and an image acquisition module is installed inside the lower shell 2 corresponding to the image acquisition hole 3; a supplementary lighting system is provided around the image acquisition module; the control unit is electrically connected to the photosensitive sensor, the supplementary lighting system, the transmission module, and the image acquisition module; the battery powers the control unit, the photosensitive sensor, the supplementary lighting system, the transmission module, and the image acquisition module.

[0024] This front-end data acquisition and transmission device is installed above the cracks in the building to be detected. It acquires images of the cracks via an image acquisition module and transmits these images to the intelligent processing center of the intelligent crack monitoring system's cloud platform for processing. Compared to manual inspection, this reduces subjective monitoring errors, saves manpower, and allows for real-time monitoring, enabling timely detection of safety risks. A photosensor detects ambient light and transmits this information to the control unit. Based on the received light information, the control unit sends instructions to the supplementary lighting system, which then adjusts the lighting in the image acquisition area according to the ambient light conditions. This allows the device to adapt to different environments and times, ensuring image clarity for subsequent image processing and analysis. Furthermore, this front-end data acquisition and transmission device adopts an integrated design and modular layout, with each unit installed independently, facilitating maintenance and upgrades.

[0025] This embodiment provides a front-end acquisition and transmission device for an intelligent crack monitoring system. The lower shell 2 has an image acquisition module installation compartment 4 that can be detachably installed in the image acquisition hole 3. The image acquisition module is installed in the image acquisition module installation compartment 4.

[0026] The image acquisition module is fixedly installed through the image acquisition module installation compartment 4, making the installation of the image acquisition module more stable.

[0027] This embodiment provides a front-end acquisition and transmission device for an intelligent crack monitoring system. The top of the image acquisition module installation chamber 4 has a stepped platform 5 protruding outward. The stepped platform 5 has several light-transmitting holes 6 circumferentially opened. The supplementary lighting system is correspondingly set above the stepped platform 5 and emits light towards the light-transmitting holes 6.

[0028] The light emitted by the supplementary lighting system is diffused through several light-transmitting holes 6 towards the image acquisition area corresponding to the image acquisition hole 3. This allows the light to illuminate the image acquisition area from different angles, reducing shadows caused by a single light source and preventing shadows from obscuring parts of the crack and affecting the monitoring effect. At the same time, a reasonable supplementary lighting angle and intensity can also reduce reflections on the surface of the acquisition area, making the acquired image more realistically reflect the actual situation of the crack.

[0029] This embodiment provides a front-end acquisition and transmission device for an intelligent crack monitoring system, wherein a transparent plate is fixedly installed inside the image acquisition hole 3.

[0030] The transparent plate ensures the passage of supplementary light and image acquisition, while sealing the image acquisition hole 3 to prevent external impurities from entering and affecting the internal environment of the casing. It also provides a certain degree of protection for the image acquisition module, supplementary lighting system, and other components inside the casing.

[0031] This embodiment provides a front-end acquisition and transmission device for an intelligent crack monitoring system. The battery is electrically connected to a low-power management unit 7, which supplies power to the control unit, photosensitive sensor, supplementary lighting system, transmission module and image acquisition module.

[0032] The low-power management unit 7 can optimize battery power consumption, provide stable power supply for the device, and extend the device's operating time.

[0033] This embodiment provides a front-end acquisition and transmission device for an intelligent crack monitoring system. The supplementary lighting system is an LED light strip, and the image acquisition module is a high-resolution camera with a macro lens.

[0034] LED light strips feature high brightness, low power consumption, and stable light emission, and can also be adjusted for adaptive lighting in image acquisition. High-resolution cameras with macro lenses allow for close-up focusing and detailed imaging of minute cracks. This enables the acquisition of localized crack details without sacrificing image quality, facilitating the detection of early-stage, smaller cracks and improving the sensitivity and accuracy of crack monitoring.
