Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of biometric adaptive instrument interaction, and particularly to a biometric adaptive instrument interaction system for industrial vehicle driving safety. Background Art
[0002] In the intelligent and safe driving management of industrial vehicles, the application of driver identification and interaction systems is crucial. With the development of industrial automation and intelligent driving technologies, traditional driver authentication methods face many challenges. For example, verification means such as keys, IC cards, or passwords are easily lost, forgotten, or copied, making it difficult to effectively prevent unauthorized operations. These verification methods rely on physical media and have low security. Once lost or stolen, they may lead to serious safety accidents. In addition, traditional authentication methods cannot monitor the driver's state in real time and lack effective means to deal with situations such as fatigue driving and driver identity changes.
[0003] Some current intelligent identity recognition systems have started to introduce biometric recognition technologies, especially face recognition technologies, to improve the security and convenience of authentication. Face recognition technology uses deep learning models to compare identities through facial features, which can effectively prevent illegal use and reduce security risks caused by human operations. However, most existing face recognition systems are applied in static environments or fixed devices, such as access control systems and attendance devices. In the industrial vehicle driving environment, factors such as complex lighting conditions, dynamic posture changes, partial occlusion, and vibration interference will reduce the accuracy of face recognition. In addition, existing face recognition methods still have deficiencies in recognition accuracy and stability when dealing with complex backgrounds, low-light environments, and high-speed dynamic changes, resulting in possible misidentifications or rejections in driver identity verification and affecting the normal use of vehicles.
[0004] To address these problems, some existing technologies have begun to combine deep learning with embedded computing to improve the real-time performance and robustness of face recognition. For example, some systems use convolutional neural networks (CNNs) for feature extraction and combine attention mechanisms to optimize the feature representation of key regions. However, these methods still have limitations. First, the efficiency of feature extraction is low. Traditional CNN structures are difficult to balance computational complexity and recognition accuracy, resulting in inefficient operation of embedded systems. Second, most current face recognition systems are based on static database matching and lack the adaptive ability for real-time driving environments, making it difficult to handle lighting, angle changes, and personalized features of different drivers. In addition, existing recognition methods mainly rely on fixed feature templates for comparison and cannot dynamically optimize feature selection, resulting in insufficient robustness in the face of environmental changes.
[0005] On the other hand, the interaction methods of existing industrial vehicle instrument systems are relatively traditional, mainly relying on physical buttons, touchscreens, or voice commands for operation, lacking real-time monitoring and adaptive adjustment of the driver's identity information. These interaction methods usually do not have a security verification function, and the driver may accidentally touch or perform unauthorized operations during the operation, increasing potential safety hazards. In addition, most existing instrument interaction systems lack intelligent data analysis functions and cannot perform adaptive adjustments in combination with factors such as the driver's identity and environmental conditions, making it difficult to efficiently manage the system in a multi-user environment. For example, in a factory or logistics warehousing environment, multiple drivers share the same industrial vehicle, and the system cannot perform personalized settings according to the habits and permissions of different drivers, resulting in increased management complexity and even potentially affecting operation safety.
[0006] To improve the driving safety of industrial vehicles, in recent years, some studies have attempted to apply optimization algorithms to face recognition to improve the efficiency of feature extraction and identity verification. For example, some methods introduce optimization algorithms such as ant colony optimization algorithm and particle swarm optimization algorithm to optimize the feature matching process to improve the recognition accuracy. However, the search efficiency of traditional optimization algorithms in high-dimensional feature spaces is relatively low, and it is difficult to quickly converge to the optimal solution, affecting real-time performance. In addition, these methods usually rely on fixed feature mapping strategies and lack the ability of adaptive optimization for complex driving environments, resulting in a decrease in recognition accuracy under conditions such as light changes and partial occlusion.
[0007] Most existing face recognition optimization methods are mostly limited to a single feature extraction strategy and cannot fully utilize the multi-scale information expression ability of deep learning networks. For example, some studies use standard convolutional neural networks (CNNs) for feature extraction, but the CNN structure has the problem of limited local feature expression and is difficult to capture global features. Although the self-attention mechanism (Transformer) can model long-range feature dependencies, its computational complexity is relatively high and it is difficult to operate efficiently on embedded systems. In addition, existing feature optimization methods mainly focus on the feature selection level and lack end-to-end optimization of the feature extraction process, resulting in the recognition results being limited by the quality of the initial features and unable to fully adapt to complex environmental changes.
[0008] Generally speaking, the existing industrial vehicle driver identity recognition systems mainly have the following defects: First, the traditional identity verification method has low security and is easily forged or bypassed; second, the existing face recognition methods lack robustness in complex driving environments and are difficult to cope with light changes, pose changes, and dynamic interferences; third, the existing deep learning models have low computational efficiency on embedded systems and are difficult to achieve efficient and real-time identity recognition; finally, the existing instrument interaction systems lack the ability to link with the driver's identity information and are difficult to achieve intelligent management.
[0009] In view of these problems, the present invention proposes a biometric adaptive instrument interaction system for industrial vehicle driving safety, which uses the VoVNet-ETSformer network for efficient feature extraction and combines an improved artificial bee colony optimization algorithm (I-ABC) to optimize the feature selection process, enhancing the recognition accuracy and real-time performance. This system integrates a face acquisition, face recognition, data storage, communication, and control module in the industrial vehicle instrument to achieve efficient verification of the driver's identity and improve the system's adaptive ability by combining intelligent optimization algorithms. Through innovative optimization strategies, the present invention improves the stability of face recognition in complex driving environments, enhances the security and intelligence level of the instrument interaction system, and solves a number of key problems in the prior art.
[0010] Therefore, how to provide a biometric adaptive instrument interaction system for industrial vehicle driving safety is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0077] The present invention combines the VoVNet-ETSformer deep learning model, the improved artificial bee colony optimization algorithm (I-ABC), and the intelligent instrument interaction system, and has made remarkable technological progress in the identity recognition and interaction management of industrial vehicle drivers, which is specifically reflected in the following three beneficial effects:
[0078] (1) The present invention uses the VoVNet-ETSformer deep learning model for efficient feature extraction and identity recognition. Combining multi-scale feature extraction, dilated convolution, and self-attention mechanism, it can still maintain high-precision face recognition ability under complex working conditions such as light changes, driver posture changes, and partial occlusion. At the same time, the multi-scale alignment method is used to perform geometric transformation on facial features, improving the robustness of the model and ensuring that different drivers can quickly and accurately pass the identity verification, reducing the occurrence probability of misrecognition and rejection. Compared with the traditional identity verification methods based on IC cards or passwords, the biometric recognition system of the present invention is more secure and difficult to be forged or bypassed, effectively preventing unauthorized personnel from driving the vehicle and improving the safety of vehicle management.
[0079] (2) In the process of feature optimization, the present invention introduces an improved artificial bee colony optimization algorithm (I-ABC), including feature screening in the employed bee stage, global search in the scout bee stage, and local optimization in the follower bee stage, ensuring rapid convergence to the optimal feature subset in the high-dimensional feature space. The global search strategy of chaotic mapping is used to avoid the optimization falling into local optimum, and the Lévy Flight search strategy is combined to further optimize the feature subset, improving the real-time performance of identity recognition. At the same time, an adaptive mutation mechanism is adopted to adjust the feature subset, enhancing the stability of feature selection, enabling the system to operate efficiently in different driving environments. Compared with the traditional CNN model, the computing efficiency is improved, and the consumption of computing resources is reduced, enabling the present system to operate efficiently in embedded industrial instruments and meet the real-time requirements of vehicle intelligent interaction.
[0080] (3) The present invention integrates intelligent data storage, encrypted communication, and control modules in the industrial vehicle instrument interaction system, dynamically adjusts the driver's permissions based on the authentication results, and encrypts the communication data, improving the security of the system. In addition, the system can adaptively adjust the interaction interface according to the driver's identity, operation habits, and environmental status, providing personalized instrument display solutions for different drivers and enhancing the user experience. At the same time, the system can monitor the driver's operation status in real time, prompt or restrict abnormal driving behaviors (such as fatigue driving, illegal operations), effectively reducing the safety risks of industrial vehicles and improving the intelligent management level. Compared with the existing industrial vehicle instrument systems, the present invention realizes the deep integration of identity recognition and instrument interaction, significantly enhancing the intelligent and automated management capabilities of industrial vehicles.
[0081] In summary, the present invention not only improves the security and accuracy of industrial vehicle driver authentication, but also optimizes feature extraction and computing efficiency, while enhancing the intelligent management capabilities of the instrument interaction system, providing an innovative solution for the safe driving and efficient management of industrial vehicles.

[0152] Example 1:
[0153] To verify the feasibility of the present invention in implementation, the present invention is applied to the intelligent logistics vehicle management system of a large industrial park. The park contains multiple workshops and warehousing areas, and there are hundreds of industrial vehicles (such as forklifts, tractors, automatic guided vehicles AGV) performing handling, distribution, and loading / unloading tasks in different areas on a daily basis. Due to the large number of industrial vehicles in the park and the chaotic management of driver identities, there are security risks such as unauthorized driving and misoperation. In addition, since drivers often need to change vehicles, the traditional identity verification methods based on IC cards or passwords are not only inefficient but also prone to card loss or password leakage, affecting normal operations.
[0154] The biometric adaptive instrument interaction system for industrial vehicle driving safety of the present invention is tested and applied in this scenario. The system first integrates a key module, a face acquisition module, a face recognition module, a storage module, a communication module, and a control module on the instrument panel of the industrial vehicle. After the driver enters the vehicle, the key module triggers the face acquisition module to collect face images, and performs feature extraction and comparison through the VoVNet-ETSformer network, and combines the improved artificial bee colony optimization algorithm (I-ABC) for feature optimization. The entire recognition process takes less than 1.2 seconds, and the driver can quickly complete identity verification without using a key or an IC card. After the identity verification is passed, the system will automatically load the operation permissions of the driver and adjust the instrument interface according to his operation habits, such as adjusting the brightness of the instrument panel and displaying the layout of the most commonly used control buttons.
[0155] The following are the performance test data of the system under different environments and working conditions:
[0156] Table 1: Performance test results of the biometric adaptive instrument interaction system for industrial vehicle driving safety
[0157] ;
[0158] During the specific testing process, the system conducts face recognition tests under different conditions, including daytime, nighttime, strong light, low light, and complex environments (such as changing lighting in a warehouse and a driver wearing a safety helmet). The experimental results show that the face recognition system of the present invention maintains a high recognition accuracy under various lighting conditions, with an average accuracy rate of 99.2%, which is approximately 3.5% higher than that of traditional CNN recognition models. In addition, in dynamic environments (such as a driver walking towards a vehicle from a distance and approaching the camera from different angles), the system can still complete identity verification within 1.5 seconds, and the rejection rate is lower than 0.8%. Under extreme lighting changes (such as direct sunlight and backlight environments), the recognition accuracy still remains above 97.5%, demonstrating strong environmental adaptability.
[0159] To further verify the security of the intelligent instrument interaction system of the present invention, the system simulates various unauthorized driving scenarios, such as: a non-registered driver attempting to start the vehicle, abnormal driver identity information (such as wearing a mask and covering part of the face), etc. The results show that the system successfully intercepts 98.7% of illegal driving attempts, provides safety prompts on the dashboard, and sends abnormal driving alerts to the background management system through the communication module. In addition, the encryption communication mechanism adopted by the present invention effectively prevents the identity data from being stolen or tampered with, improving data security compared with the traditional IC card-based identity authentication method.
[0160] During the peak scheduling period of industrial vehicles (such as 9:00 - 11:00 am and 14:00 - 16:00 pm every day), the traditional IC card or password verification method usually results in a long queue waiting time, with an average verification time of about 8.5 seconds for each vehicle. However, with face recognition, this system only requires 1.2 seconds, significantly improving the vehicle usage efficiency.
