Description

Technical Field

[0002] Vehicle-mounted lighting monitoring is mainly used for performance testing of vehicle lighting systems such as headlights, taillights, and turn signals to ensure compliance with safety regulations. Visual inspection refers to the process of converting the captured target into an image signal using machine vision products (i.e., image acquisition devices, which are divided into CMOS and CCD types), transmitting it to a dedicated image processing system, and converting it into a digital signal based on pixel distribution, brightness, color, and other information. The image system performs various calculations on these signals to extract the target's features, and then controls the on-site equipment actions based on the judgment results. Machine vision-based lighting detection technology can achieve high-precision, automated, and non-contact measurement, making it the mainstream solution in the industry.

[0003] Existing vehicle-mounted headlight monitoring devices rely on manual visual inspection or simple photoelectric sensors for traditional detection, which suffers from low efficiency, strong subjectivity, and difficulty in quantification. At the same time, existing headlight monitoring devices are not convenient to adjust according to the distance of the headlights during actual use, and the monitoring of headlight color is not comprehensive enough, resulting in poor image or video recording quality and difficulty in effectively analyzing headlight color, leading to inaccurate prediction and evaluation of vehicle headlights.

[0009] Furthermore, the power distribution unit includes a transmission module, an analysis module, and a power supply module. The transmission module consists of a voltage regulator, multiple transistors, and a DC power supply.

[0010] Furthermore, the multiple transistors are of the same type and are connected in parallel, and the collectors of the multiple transistors are electrically connected to the vehicle power supply, and the bases of the multiple transistors are electrically connected to a capacitor and grounded.

[0015] This utility model discloses a vehicle-mounted real-time light and color monitoring device. By setting up a mounting bracket and driving components, it can effectively drive the angle adjustment of the monitoring mechanism to adapt to the light positions at different distances.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1 to 5 As shown, a vehicle-mounted real-time headlight color monitoring device includes a mounting bracket 10, one side of which is fixedly connected to a drive element 101.

[0025] The monitoring mechanism 20 includes an adjustment housing 21, which is rotatably connected to the other side of the mounting bracket 10 and slidably connected to the output end of the drive element 101. The interior of the adjustment housing 21 is fixedly connected to the monitoring camera 22.

[0026] The monitoring unit 20 also includes a computing unit, a transmission unit, and a power distribution unit. The computing unit includes an image analysis module and an image acquisition module. The monitoring camera 22 is electrically connected to the image analysis module and the image acquisition module. The power distribution unit is electrically connected to the vehicle power supply.

[0027] In this embodiment, it should be noted that the monitoring mechanism 20 is also equipped with a 5G transmission module, which is electrically connected to the monitoring camera 22, enabling effective connection with the vehicle owner's mobile phone and sending monitoring data to the vehicle owner's mobile phone. The power distribution unit provides power for data transmission, image analysis, and image acquisition. The detection camera captures the light spot distribution and chromaticity characteristics of the light, and then the image processing algorithm identifies the light pattern inflection point and color temperature deviation, which is then fed back to the vehicle owner's mobile phone via the transmission unit. This is a mature technology and will not be described in detail here. The driving element 101 is a drive motor, and a drive ring is fixed at its output end. By adjusting the sliding connection between the housing 21 and the drive ring, the monitoring mechanism 20 can be rotated, thereby adjusting it. The monitoring mechanism 20 captures the light spot distribution and chromaticity characteristics of the light from multiple angles. The image analysis module and image acquisition module within the calculation unit record and analyze the light pattern inflection point and color temperature deviation of the light, and then the data is sent to the vehicle owner's mobile phone via the transmission unit. Specifically, this device can not only monitor the light in real time but also record driving to ensure driving safety.

[0028] like Figure 4As shown, the power distribution unit includes a transmission module, an analysis module, and a power supply module. The transmission module consists of a voltage regulator, multiple transistors, and a DC power supply. The voltage regulator provides voltage regulation and, in conjunction with a resistor, ensures the stability of the load voltage. The transistors enhance the current, thereby ensuring adaptability to fluctuations in the vehicle's power supply and improving the protection performance of the monitoring device.

[0029] Preferably, multiple transistors are of the same type and connected in parallel to ensure that the transistors have the same current amplification factor, threshold voltage and other parameters, and avoid uneven current distribution due to differences in characteristics; the collectors of multiple transistors are electrically connected to the vehicle power supply, which can serve as power output terminals to ensure power supply to the monitoring camera 22; and the bases of multiple transistors are connected to a common capacitor and grounded, which can form a low-pass filter to suppress high-frequency interference.

[0030] Preferably, the vehicle power supply is electrically connected to the voltage regulator, the input terminal of the voltage regulator is connected to the vehicle power supply, and the input terminal of the voltage regulator is grounded through a capacitor; the voltage regulator can improve voltage stability, suppress input fluctuations, enhance the reliability of the monitoring mechanism 20, and extend its service life.

[0031] Preferably, the vehicle power supply is the vehicle cigarette lighter interface, which does not require changes to the vehicle wiring during monitoring and ensures stable power output.

[0032] Preferably, the monitoring mechanism 20 also includes a multi-port high-speed hub and a controller circuit, with the multi-port high-speed hub electrically connected to the controller circuit; it should be noted that the multi-port high-speed hub connects the core computing board to the solid-state storage device and the Beidou positioning module, and transmits the operating status and information to the device panel.

[0033] The working principle of this utility model is as follows: By connecting the mounting bracket 10 to the vehicle and connecting it to the vehicle's on-board power supply, the monitoring mechanism 20 is powered on when the vehicle is started, and the monitoring camera is activated to record in real time. The monitoring camera 22 and the image acquisition module capture the light spot distribution and chromaticity characteristics of the light, and transmit the captured features to the image analysis module. The light signal is converted into a digital image through the image processing algorithm. At the same time, the algorithm analyzes the light spot shape, brightness distribution, chromaticity coordinates, etc., and then effectively compares them with the preset standards to determine whether the light is qualified, predict its lifespan, and provide early warning of vehicle light malfunctions.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
