Description

Technical Field

[0001] This utility model relates to the field of T-beam appearance quality inspection, and in particular includes a light strip device used in a precast T-beam appearance quality inspection system. Background Technology

[0002] With the rapid expansion of infrastructure and the surge in the number of bridges, their construction quality and safety, as a crucial component of transportation infrastructure, have received high attention. T-beams are typically made of precast concrete or reinforced concrete, and can be prefabricated in factories and then transported to the construction site for installation. Pre-installation visual quality inspection is usually done manually, which suffers from strong subjectivity, inadequate technical methods, insufficient inspection personnel, and imperfect data management systems. This makes it difficult to detect and address potential risks in some bridges in a timely manner, failing to meet the current requirements for high-efficiency and high-precision inspection of bridges.

[0003] To overcome the shortcomings of traditional inspection methods, the industry has been exploring more advanced and intelligent means of inspecting the appearance quality of T-beams. With the rapid development of computer vision, especially deep learning and convolutional neural networks (CNNs), image recognition technology has become increasingly mature and plays an increasingly important role in various industries, driving intelligent processes and innovative applications. However, in the application scenarios of T-beam appearance quality inspection, there is a lack of dedicated equipment and systems, making it difficult to achieve automated acquisition, automated inspection, and intelligent evaluation of T-beam appearance quality.

[0004] Traditional lighting systems typically use ordinary headlights, some of which are not even LED bulbs, leading to problems such as insufficient brightness, color difference, and lack of adjustability. Applying such lighting systems to the appearance quality inspection of precast T-beams presents two main problems: 1) Traditional lighting devices cannot meet the requirements for high-precision inspection in terms of brightness, uniformity, stability, color rendering, and multiple brightness adjustments, thus reducing inspection accuracy; 2) Traditional lighting devices only provide supplementary light sources and cannot offer warning or alert functions, failing to meet the safety requirements of the complex environment at precast beam yards, and their functionality cannot satisfy the needs of multiple scenarios.

[0005] In view of the shortcomings of existing technical solutions, there is an urgent need for a light strip device for the appearance quality inspection system of precast T-beams to improve the inspection accuracy and reduce the risk of safety hazards. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a light strip device for use in a precast T-beam appearance quality inspection system.

[0007] This light strip device, used in the precast T-beam appearance quality inspection system, is installed on the opposite surfaces of the columns on both sides of the inspection gantry. The light strip device includes: LED supplementary light strip, LED signal light strip, and light strip controller.

[0008] LED supplementary lighting strips are used to illuminate the inside of the detection gantry, and LED signal light strips are used to reflect the working status of the monitoring system.

[0009] On one side of the column, LED fill light strips and LED signal light strips are respectively arranged on both sides of the column. The LED fill light strips and LED signal light strips are respectively connected to the light strip controller, which is used to receive input signals and control the LED fill light strips and LED signal light strips.

[0010] Preferably, two recessed slots are provided on the opposite surfaces of the two columns of the inspection gantry, and LED supplementary light strips and LED signal light strips are respectively embedded in the two recessed slots.

[0011] Preferably, the light strip controller is installed below the inspection gantry column, connecting the bottom end of the LED supplementary light strip and the LED signal light strip; the light strip controller is installed on the opposite surfaces of the two side columns of the inspection gantry.

[0012] Preferably, the camera on the inspection gantry is located between the LED supplementary lighting strip and the LED signal light strip.

[0013] Preferably, the light strip controller includes a power supply module for providing constant voltage or constant current output; an MCU microcontroller for receiving input signals and generating corresponding control signals to execute pre-programmed control logic; and an LED driver circuit for converting the low-level signal output by the MCU microcontroller into a high-current signal to drive the LED fill light strip and LED signal light strip.

[0014] The beneficial effects of the utility model are:

[0015] 1) This utility model has embedded slots on the opposite surfaces of the two columns of the detection gantry. LED supplementary light strips and LED signal light strips are installed in the embedded slots. Through the light strip controller, it can cope with complex external light source environment, so that the LED supplementary light strips can provide reliable shooting light source, improve image acquisition quality and image detection accuracy.

[0016] 2) This device not only provides a reliable light source for industrial camera shooting by setting LED supplementary light strips and LED signal light strips on both sides of the detection gantry, but also displays the working status of the gantry detection device by controlling the dynamic light source of the LED signal light strips to emit various signals. This serves to convey the working status and reduce on-site safety risks. In addition, the signals of the LED signal light strips are adjustable and will not cause interference during shooting.

[0020] The present invention will be further described below with reference to embodiments. The description of the embodiments below is only for the purpose of helping to understand the present invention. It should be noted that, for those skilled in the art, several modifications can be made to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0021] As one example, such as Figure 1 and Figure 2 As shown, this light strip device used in the precast T-beam appearance quality inspection system is installed on the opposite surfaces of the columns on both sides of the inspection gantry 5. The light strip device includes: LED supplementary light strip 2, LED signal light strip 3 and light strip controller 4; the inspection gantry 5 is also equipped with a shooting device and a spraying device.

[0022] like Figure 2 As shown, two recessed slots 1 are provided on the opposite surfaces of the two columns of the detection gantry 5. The slots are formed by leveling the columns of the detection gantry 5 and embedding them into clampable slots. LED supplementary light strip 2 and LED signal light strip 3 are respectively embedded in the two recessed slots 1.

[0023] The camera on the inspection gantry 5 is located between the LED supplementary light strip 2 and the LED signal light strip 3.

[0024] LED supplementary light strip 2 is used to illuminate the inside of the detection gantry 5, with a brightness of 1000lm / m, a CRI of 80, 120 LED chips, and support for PWM brightness adjustment, meeting the requirements of high-precision detection in terms of brightness, uniformity, stability, color rendering, and multiple brightness adjustments.

[0025] LED signal light strip 3 is used to reflect the working status of the monitoring system. It has a brightness of 300 lm / m, a CRI of 80, 30 LED chips, supports PWM brightness adjustment, and supports dynamic effects such as flashing and gradation, providing prompts and warnings.

[0026] On a single-sided column, LED supplementary lighting strip 2 and LED signal light strip 3 are respectively arranged on both sides of the column. The light strip controller 4 is installed below the opposite side of the column of the inspection gantry 5 for easy maintenance. The light strip controller 4 is connected to the bottom end of LED supplementary lighting strip 2 and LED signal light strip 3; it is used to receive external input control signals and control LED supplementary lighting strip 2 and LED signal light strip 3.

[0027] The LED strip controller 4 includes a power module, an MCU microcontroller, an LED driver circuit, an input / output interface, and a heat dissipation device.

[0028] The power module is used to provide constant voltage or constant current output; the MCU microcontroller is responsible for receiving input signals and generating corresponding control signals, executing pre-programmed control logic, including color changes, dynamic effects (such as flashing, gradation), timing control, etc.

[0029] The LED driver circuit is used to convert the low-level signal output by the MCU microcontroller into a high-current signal to drive the LED fill light strip 2 and the LED signal light strip 3.

[0030] When installing this type of LED strip device used in the precast T-beam appearance quality inspection system:

[0031] The grooves in the gantry 5 columns are leveled to meet the dimensional requirements of the embedded slot 1; the LED supplementary lighting strip 2 and the LED signal light strip 3 are installed in the embedded slot 1 respectively; the light strip controller 4 is installed on the lower side of the gantry column. The input port of the light strip controller 4 is connected to the power supply, and the output port is connected to the LED supplementary lighting strip 2 and the LED signal light strip 3.

[0032] The pre-programmed LED strip controller 4 enables the LED signal strip 3 to emit a flashing red light at the start of the inspection, a green light during the inspection, and a blue light after the inspection, thus indicating the working status of the precast T-beam appearance quality inspection system to on-site personnel and reducing safety risks. Specifically, in use:

[0033] After the gantry 5 begins to move, the LED strip controller 4 receives the start signal and controls the LED signal strip 3 to flash red light, alerting nearby workers that the inspection is about to begin. After the gantry spray system is activated, the LED strip controller 4 receives the in-inspection signal and controls the LED signal strip 3 to display a low-brightness green light to indicate that the inspection is in progress, without interfering with the light emitted by the LED supplementary lighting strip 2. Simultaneously, the LED strip controller 4 controls the LED supplementary lighting strip 2 to start working, providing a light source for photography. After the gantry spray system is shut down, the LED strip controller 4 receives the end signal and controls the LED signal strip 3 to display a high-brightness blue light to indicate that the inspection is complete. It then controls the LED supplementary lighting strip 2 to stop working and turn off its light source.
