Description

Technical Field

[0001] This utility model relates to the field of image recognition technology, and in particular to a ground oil stain recognition device. Background Technology

[0002] During the operation of power plants, mechanical equipment that relies heavily on lubricating oil, hydraulic oil, or fuel oil is prone to oil leakage and dripping onto the ground due to equipment aging, seal failure, or improper operation. This not only affects the cleanliness of the production area and daily management, but also poses risks such as causing people to slip and fall, fires and explosions, and the expansion of equipment failures. Currently, power plants mainly rely on manual inspections and video surveillance combined with traditional image processing for oil stain detection. However, manual inspections have problems such as limited coverage, poor real-time performance, and results that depend on the experience and attention of personnel. Traditional image acquisition devices are severely affected by lighting interference, are difficult to adapt to the diverse forms of oil stains, and lack real-time performance. Summary of the Invention

[0013] Preferably, the controller uses an ESP32 chip with a built-in Wi-Fi module, which connects wirelessly to the host computer.

[0014] This utility model provides a ground oil stain identification device, which has the following beneficial effects: 1. Enhanced recognition flexibility and adaptability: The device is equipped with two cameras that can move along the two sides of an L-shaped chute, forming a binocular camera. With the help of a sliding device consisting of a slider, lead screw, and motor, the baseline distance and angle of the two cameras can be flexibly adjusted according to monitoring needs. This adapts to monitoring scenarios in different areas of the power plant (such as equipment gaps, roads, pump rooms, etc.), satisfying both close-range accurate capture and long-range large-area monitoring, thus solving the problem of limited coverage of traditional fixed cameras.

[0015] 2. Enhanced recognition capabilities in complex environments: An infrared camera is added to the front of the circular housing, which can effectively capture the characteristics of oil stains on the ground under complex lighting conditions such as night, low light, or strong light reflection. This makes up for the shortcomings of traditional visible light cameras that are affected by light interference. Combined with the image acquisition capabilities of dual cameras, it further improves the accuracy of oil stain recognition and reduces missed or false judgments caused by environmental factors.

[0016] 3. Reduce maintenance costs and ensure equipment stability: The transparent lens cover on the surface of the L-shaped slide can effectively isolate dust and oil mist in the power plant environment, protect the camera lens from contamination, reduce the frequency of lens cleaning and maintenance, extend the service life of the equipment, and at the same time ensure the clarity of the acquired images, providing high-quality data support for subsequent identification.

[0017] Simplify installation and debugging and expand coverage: The circular shell is hinged to the base through the connecting part, which can flexibly adjust the monitoring angle of the device; the base has anti-slip grooves on both sides and is connected to the mounting plate, which not only makes it easy to hold and fix during installation, but also stably adapts to different installation scenarios such as ground, wall, bracket, etc., easily achieving multi-area coverage and solving the problems of inconvenient installation and fixed angle of traditional devices.

[0018] 4. Achieve intelligent and real-time monitoring: The control box inside the housing integrates an ESP32 chip controller. The camera, infrared camera, and motor are all electrically connected to the controller, and the controller can wirelessly communicate with the host computer via a built-in WiFi module. It can automatically control the movement of the camera, data acquisition and transmission without the need for manual on-site operation. It feeds back the monitoring data to the host computer in real time, improves monitoring efficiency, reduces the cost of manual inspection, and avoids the shortcomings of poor real-time performance and reliance on subjective experience in manual inspection, ensuring the timeliness and objectivity of oil stain identification. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments: Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the internal structure of the present invention; Figure 3 This is a schematic diagram of the sliding device of this utility model; Figure 4 This is a side view of the present invention; Figure 5 This is a schematic diagram of the external structure of this utility model. Detailed Implementation

[0020] like Figure 1-2 As shown, a ground oil stain identification device includes a circular housing 1. An L-shaped groove 3 for sliding cameras 2 is provided at the front end of the circular housing 1. Two cameras 2 are provided, and each camera 2 moves along one of the two sides of the L-shaped groove 3. A sliding device for moving the cameras 2 is provided inside the circular housing 1. The L-shaped groove 3 is used to adjust the baseline distance and angle between the two cameras, facilitating flexible setting of imaging parameters according to the monitoring scenario (such as close-range ground monitoring or long-range large-area monitoring). This enhances the versatility and adaptability of the device, meeting the installation requirements of different areas in power plants (equipment rooms, plant roads, oil pump rooms, etc.). The two cameras are used to simultaneously acquire two high-definition images, and three-dimensional depth information of the ground is obtained through parallax calculation, enabling accurate differentiation between oil stains and easily confused objects such as ordinary water stains and shadows. Image clarity can be guaranteed under complex lighting conditions, and the reliability of oil stain identification is enhanced by depth information.

[0021] Preferably, the front end of the circular housing 1 is further equipped with an infrared camera 4. The infrared camera is used to collect the thermal characteristics or spectral reflectance characteristics of the ground in the infrared band, thereby enhancing the identification of oil-stained areas. It can effectively detect oil stains at night or in low light conditions, compensating for the shortcomings of visible light cameras in low-light environments. Infrared imaging has a strong ability to distinguish between the temperature difference and spectral absorption characteristics of oil stains and the ground, making it particularly suitable for outdoor areas of power plants or environments with unstable ambient light.

[0022] Preferred, such as Figure 3 As shown, the sliding device includes a slider 5 housed within a slide rail 7 and a lead screw 6 for moving the slider 5. A camera 2 is fixedly mounted on the slider 5, and a motor 13 drives the lead screw 6 to rotate. The lead screw drive features high precision and smooth operation. Combined with the motor drive, it can automatically control the camera's movement distance and position, avoiding errors from manual adjustments and ensuring the camera accurately aligns with the monitoring target. This provides high-quality, accurate image data for subsequent oil stain identification, improving the automation and precision level of the device.

[0023] Preferably, the surface of the L-shaped groove 3 is provided with a transparent lens cover 8. Power plant areas contain pollutants such as dust and oil mist. The transparent lens cover can prevent these pollutants from adhering to the camera lens, thus extending the lens's lifespan and avoiding image blurring caused by lens contamination. This ensures the clarity of image acquisition and provides a fundamental support for the accuracy of oil stain identification.

[0024] Preferably, the circular housing 1 is hinged to the base 10 via the connecting part 9. The hinge structure allows the circular housing to rotate around the base, and the orientation of the camera and infrared camera can be adjusted according to monitoring needs (such as fine adjustment of the tilt and elevation angles) to adapt to ground monitoring needs at different heights and in different directions.

[0025] Preferably, the base 10 is connected to the mounting plate 11. The mounting plate secures the device to the ground, wall, or metal bracket. Installation is simple, disassembly is convenient, and future equipment maintenance and replacement are easy. Figure 4 The image shown is a side view of the device, which can be fixed to a wall.

[0026] Preferably, the base 10 has anti-slip grooves 12 on both sides. The anti-slip grooves can increase the friction when the hand grips the base, prevent the base from slipping during installation, and facilitate accurate alignment and installation by the staff.

[0027] Preferably, a control box 14 is provided inside the circular housing 1, and a controller is provided inside the control box 14. The camera 2 and the infrared camera 4 are electrically connected to the input terminal of the controller, and the motor 13 is electrically connected to the output terminal of the controller. The controller can synchronously receive the data collected by the camera and the infrared camera, and drive the motor to adjust the position of the camera, forming a closed-loop control of "data acquisition, position adjustment, and precise acquisition", reducing manual intervention and improving the coordination and automation efficiency of the device operation.

[0028] Preferably, the controller is wirelessly connected to the host computer.

[0029] Preferably, the controller uses an ESP32 chip with a built-in Wi-Fi module, which wirelessly connects to the host computer. The ESP32 chip integrates Wi-Fi functionality, eliminating the need for an additional wireless communication module, reducing the number of internal components and simplifying circuit design. Furthermore, the integrated chip is lower in cost and smaller in size, reducing the overall cost of the device and fitting into the compact space of a circular casing, ensuring the simplicity and practicality of the device structure.

[0030] This utility model addresses the need for oil pollution identification on power plant floors. Its structural design features a circular housing with an L-shaped sliding groove at the front for moving two cameras. A sliding device consisting of a slide rail, slider, lead screw, and motor allows for flexible camera position adjustment. An infrared camera is also included to adapt to complex lighting environments such as nighttime and low light conditions. For protection and installation compatibility, a transparent lens cover protects the camera lenses on the L-shaped sliding groove. The circular housing is hinged to the base via a connecting part to adjust the monitoring angle. The base connects to a mounting plate and has anti-slip grooves on both sides, facilitating stable installation on various surfaces such as the ground and walls. For control and data transmission, the control box inside the housing integrates an ESP32 controller with a built-in WiFi module. This controller can control the cameras, infrared camera, and motor, and achieve wireless communication with a host computer, enabling automated and remote oil pollution monitoring. This effectively solves the problems of limited coverage, susceptibility to environmental interference, and the need for manual intervention associated with traditional detection methods.
