Abstract
Description
Technical Field
[0001] The present invention relates to an anti-collision warning system and warning method for mining operation vehicles based on zonal warning, belonging to the technical field of intelligent safety warning. Background Art
[0002] Nowadays, mineral resources are an important foundation for industrial development. During the operation process in mining areas and underground, the safety protection problem of mining vehicles has become increasingly prominent. Traditional mining vehicle operations mainly rely on manual observation and basic video monitoring systems. This method has problems such as many monitoring blind spots, poor real-time performance, and great potential safety hazards in practical applications. Existing video monitoring technologies mainly rely on embedded technologies and use network and communication technologies as platforms. Basic image analysis algorithms are embedded in monitoring cameras to form a digital and networked monitoring system, which has improved the automation level of safety monitoring to a certain extent. However, in a complex mining area environment, especially in harsh conditions such as insufficient light and large dust, the reliability and real-time performance of such basic visual monitoring systems are difficult to guarantee.
[0003] In recent years, with the rapid development of computer vision and artificial intelligence technologies, object detection methods based on deep learning have shown great application potential in the field of safety warning due to their powerful feature extraction and object recognition capabilities. At the same time, ultrasonic ranging technology has unique advantages in detecting obstacles at close range due to its stable and reliable distance measurement characteristics. However, existing safety protection systems often adopt a single sensor solution and lack a scientific and reasonable warning zoning strategy, and cannot provide multiple levels of protection measures according to the safety requirements of different distance ranges of operation vehicles. In practical applications, such a single protection solution often has problems such as untimely warning and high false alarm rate, and cannot effectively guarantee operation safety, and at the same time poses a potential safety hazard to the safety of operation workers.
[0004] Therefore, there is an urgent need for a warning system that can adapt to the complex mining area environment and has multi-level safety protection capabilities. Through the complementary advantages of AI visual detection and ultrasonic ranging technologies, combined with a scientific and reasonable zonal warning strategy, it can achieve comprehensive safety warning protection for mining vehicle operations to overcome the above problems.
