As the pulse of urban transportation—rail traffic—accelerates, the importance of safety becomes increasingly prominent. Laser rail detection technology emerges as the "guardian" ensuring the safe and stable operation of trains.

Leveraging outstanding diode laser packaging, coupling, and beam shaping technologies, BWT introduces the single-chip diode laser-Spatial Light product series, including models like K915FD2WN-12.00WN0N and K808FD2WN-10.00WN0N. These products provide efficient and stable laser sources for laser rail detection systems, enabling precise measurement of geometric parameters of tracks without contact. The use of these products equips rail traffic with a pair of sensitive "super eyes," achieving an extended field of view and data capture ability, thus becoming a reliable assistant in maintaining rail traffic safety.

Product Features

Laser rail detection systems are critical components of modern rail traffic safety detection, typically comprising laser emitters, receivers, and data processing units working in concert. When the laser beam accurately illuminates the track surface, the receiver captures and analyzes the reflected laser signals. By analyzing the shifts and angles of these reflected lasers, the system can accurately calculate the geometric parameters of the track, such as gauge, alignment, and elevation, ensuring the safe and stable operation of trains.

Principle of Laser Rail Detection System

As a provider of high-quality laser light sources, BWT's single-tube diode laser-Spatial Light product series possesses the following characteristics and advantages:

High Precision Measurement

The product offers stable, high-quality laser sources, ensuring precise measurement of track geometry by laser rail detection systems with millimeter-level accuracy, crucial for ensuring the safe operation of trains. This system is typically integrated into mobile engineering vehicles, train inspection stations, and train starting stations to perform contactless automated inspections, significantly reducing the workload and time of manual inspections, promptly identifying track anomalies, preventing accidents, and enhancing the safety of rail traffic systems.

Brand New Integrated Process

The innovative integrated manufacturing process of the product's lens tube shell achieves an air tightness of 10⁸, significantly enhancing structural compactness and integration, ensuring precise integration of internal components, and making it more stable and reliable in rail traffic safety detection applications.

Adaptability to Extreme Environments

The product possesses strong environmental adaptability, with carefully designed heat dissipation systems, efficient sealing structures, and high-quality weather-resistant materials, ensuring stable operation under various climates and lighting conditions, including harsh environments such as dust, rain, and snow, thereby guaranteeing the normal operation of laser rail detection systems.

Dust-proof Design

The product adopts a dust-proof design, ensuring cleanliness and dryness inside the laser, through strengthened sealing and integrated dust-proof design. This design effectively isolates the interference of dust and other debris, ensuring stable performance and service life of the laser, significantly reducing equipment maintenance costs, and providing a convenient and economical solution for rail traffic safety detection.

Application Scenarios

Tunnel Detection

In tunnel detection, the product can accurately inspect the initial layer and peeling of tunnel lining, evaluate whether the damage rate is controlled within a safe range, and detect potential safety hazards such as debris, pits, and cracks inside the tunnel. Through a detection system installed on dedicated engineering vehicles, this laser achieves comprehensive monitoring of tunnel safety.

Railside Body Detection

In railside body detection, BWT's single-tube diode laser is mainly used to detect the shape of the body and the condition of key components. Through a detection system installed alongside the track, real-time monitoring of the deformation of the train body and the detachment or deformation of key components provides strong support for the stability and safety of train operation.
