Description

Technical Field

[0001] This utility model relates to the technical field of sound and light warning devices, and in particular to an IGV sound and light warning pedestrian warning device based on visual analysis. Background Technology

[0002] With the development of industrial automation, Industrial Guided Vehicles (IGVs) are widely used in smart factories, warehousing and logistics, and other scenarios to efficiently perform material transportation tasks. IGVs possess autonomous navigation, path planning, and dynamic obstacle avoidance capabilities, greatly improving operational efficiency. However, frequent personnel movement within factories or warehouses, especially in intersecting passageways, corners, or obstructed areas, poses a potential collision risk between IGVs and pedestrians, jeopardizing the safety of on-site workers.

[0003] To improve pedestrian safety, some IGV systems currently incorporate infrared sensors, ultrasonic radar, or fixed-point audible and visual alarms to detect obstacles or issue warnings. However, these technologies generally suffer from limited warning range, low recognition accuracy, or high false alarm rates. They are particularly vulnerable to providing real-time and accurate warning feedback in complex environments or dynamic pedestrian scenarios, which can easily lead to safety accidents.

[0004] In view of this, the inventors have specifically designed an IGV sound and light warning pedestrian reminder device based on visual analysis, which leads to this invention. Utility Model Content

[0005] (a) Technical problems to be solved The purpose of this application is to provide an IGV (In-Ground Vehicle) sound and light warning pedestrian alert device based on visual analysis, which at least solves the problem that existing IGV vehicles cannot achieve real-time pedestrian identification and directional warning during operation.

[0006] (II) Technical Solution To solve the above-mentioned technical problems, this utility model provides the following technical solution: This application provides a visual analysis-based IGV (In-Ground Vehicle) audible and visual warning pedestrian alert device, comprising: a camera module installed at the front end of the IGV vehicle body for acquiring images of the front of the vehicle; a visual processing module electrically connected to the camera module for analyzing the images and identifying the presence of a pedestrian target; and an audible and visual warning unit electrically connected to the visual processing module for issuing an audible and visual alarm signal when a pedestrian target is detected.

[0007] In a further embodiment, the camera module includes an image sensor and a lens, wherein the image sensor is used to convert the acquired image into a digital signal.

[0008] In a further embodiment, the camera module is connected to the vision processing module via a flexible ribbon cable.

[0009] In a further embodiment, the vision processing module includes an embedded processor and a memory for running object detection algorithms.

[0010] In a further embodiment, the visual processing module is preset with a pedestrian recognition threshold.

[0011] In a further embodiment, the audible and visual warning unit includes at least one buzzer and at least one LED light.

[0012] In a further embodiment, the buzzer is a 120dB pulse buzzer, and the LED light is a red flashing light.

[0013] In a further embodiment, a housing is also included, in which the camera module, the visual processing module, and the audio-visual warning unit are all installed.

[0014] In a further embodiment, the housing is provided with a dustproof structure and a waterproof structure.

[0015] In a further embodiment, the bottom of the housing is provided with an adjustable mounting bracket.

[0016] (III) Beneficial Effects Compared with the prior art, the present invention has the following advantages: This invention integrates a camera module, a visual processing module, and an audible and visual warning unit at the front end of an IGV vehicle to construct an active pedestrian warning device based on visual analysis. Compared with existing technical solutions that rely solely on infrared sensing or fixed warning devices, this device has higher target recognition accuracy and real-time performance.

[0020] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0021] like Figure 1 As shown, this utility model provides a visual analysis-based IGV (Industrial Guided Vehicle) audible and visual warning pedestrian alert device, aiming to improve the detection capability and warning efficiency of pedestrians during the operation of industrial guided vehicles (IGVs), especially suitable for industrial environments with frequent personnel flow and complex path intersections. This device is mainly integrated into the front end of the IGV vehicle, and through three core functional modules—forward data acquisition, image recognition, and audible and visual warning—it achieves proactive identification and immediate alerting of pedestrian targets ahead.

[0022] like Figure 2 As shown, the device includes a compact, one-piece rectangular housing 5. Housing 5 is made of high-temperature resistant, high-strength engineering plastic, possessing excellent dust and water resistance, making it suitable for long-term operation in industrial workshop environments with high dust levels, humidity, or large temperature variations. The front of housing 5 has an opening for mounting the camera module 1; multiple mounting positions are pre-set inside housing 5 for accommodating the vision processing module 2, power management module, and related circuitry; an independent audio-visual warning unit 3 window is located at the bottom of housing 5 to ensure that warning signals are clearly transmitted to pedestrian areas.

[0023] The camera module 1 is located inside the opening at the front of the housing 5. It is modularly packaged and houses a 120° wide-angle lens 12, matched with a megapixel CMOS image sensor 11 (such as the Sony IMX series). It supports color imaging in low-light environments and features automatic exposure, white balance adjustment, and electronic shutter functions. The camera module 1 connects to the main control board via a digital interface (such as MIPI or DVP) and is routed through a flexible ribbon cable 4 in the internal cable channel of the housing 5 to avoid interference and damage.

[0024] The vision processing module 2 is the core control unit of this invention. It is designed based on an embedded processor architecture 21, and incorporates a multi-core image processing chip and local memory 22 for running recognition algorithms. The processing module has a pre-set deep learning-based pedestrian detection model capable of recognizing pedestrian contours, movement trends, and relative distances in images. To improve recognition accuracy, the system has an adjustable risk distance threshold. When the distance between a pedestrian and the IGV (Incoming Geographic Vision) is less than the set value, the system determines it as a potential hazard and activates a warning response mechanism.

[0025] like Figure 2 As shown, the audible and visual warning unit 3 is located on the lower front side of the housing 5, and consists of multiple 120-decibel high-loudness pulse buzzers 31 and red high-brightness LED flashlights. This warning unit is electrically connected to the visual processing module 2 and activates synchronously upon receiving a hazard identification signal, emitting a high-intensity warning signal using a combination of sound and light. The LED lights 32 are arranged in a linear array structure, enabling wide-angle visibility and ensuring good alertness even in noisy or multi-person work environments.

[0026] To enable flexible deployment of the device on different types of IGV vehicles, the bottom of the housing 5 is designed with an adjustable metal mounting bracket 6. This bracket has an L-shaped structure and is fixed to the vehicle via wing screws, allowing for pitch angle adjustment. This enables the camera module 1 to adapt its shooting angle to different installation heights and road conditions. Furthermore, the entire device integrates a power management module to convert the vehicle's main power supply (e.g., 24V DC) into a low-voltage power supply (e.g., 5V / 12V) suitable for the camera module 1 and control board, providing voltage regulation protection and short-circuit protection to ensure stable operation.

[0027] Workflow Description: like Figure 3 As shown, in actual use, camera module 1 continuously acquires images of the scene in front of the vehicle and transmits the image data to vision processing module 2. The main control chip analyzes the images in real time. After identifying a pedestrian target, it immediately determines the relative position and danger level, and triggers the audio-visual warning unit 3 according to the set threshold. If the identification result is high risk, the audio-visual unit is quickly activated, emitting a strong sound and a red flash to guide pedestrians to actively avoid the danger; if the identification result is medium to low risk, only a flash warning is issued.

[0028] In addition, this device also has a reserved expansion interface, which can be linked with the IGV main control system. For example, in dangerous situations, it can be linked to control the IGV to decelerate, brake or re-avoid the path, thereby building a three-in-one safety mechanism of "identification-early warning-intervention".

[0029] This invention fully considers the adaptability to the site environment in its installation structure. Through modular and compact integrated design, it significantly improves installation convenience and operational reliability. Compared with traditional single-point audible and visual alarms or low-resolution sensing systems, this device has an integrated "identification-judgment-response" capability, enhancing the level of intelligent safety protection in industrial sites.

[0030] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
