Track/Railway

Forward Active Collision Avoidance and Foreign Object Detection for Rail Transit Vehicles

The operating environment of rail transit systems—such as mine locomotives, subway engineering vehicles, or trams—is complex and characterized by long braking distances. In the dimly lit conditions of tunnels or under harsh outdoor weather, drivers find it difficult to spot with the naked eye rocks falling onto the tracks, intruders, or stalled vehicles in a timely manner. Traditional video surveillance is heavily affected by lighting conditions, while millimeter-wave radar struggles to precisely outline the contours of obstacles, making serious collision and derailment accidents highly likely and causing significant loss of life and property.

Accurate Statistics and Analysis of Passenger Flow in 24-Hour Channels

At key nodes such as the entrances and exits of high-speed rail stations and subway stations, transfer corridors, and escalator areas, passenger flows are dense and highly dynamic. Real-time acquisition of accurate passenger flow data is crucial for station capacity scheduling, emergency alerts, and safe crowd management. Traditional video-based passenger-counting solutions often require complex background modeling and are susceptible to factors such as changes in lighting conditions (e.g., bright light or shadows), mutual occlusion among people, and varying levels of crowding, all of which can reduce counting accuracy. Moreover, in certain areas with stringent privacy requirements, video data collection also poses compliance risks.

Railway Foreign Object Intrusion Active Safety Monitoring

As the lifeline of the national economy, the safe operation of railways is of paramount importance. However, the complex geographical conditions along railway lines mean that risks such as rockfalls, mudslides, and intrusions by pedestrians or animals—known as "foreign-object encroachment"—constantly threaten train safety. Traditional video surveillance systems are easily affected by lighting conditions, rain, and snow, making it difficult to achieve precise, round-the-clock object detection. Meanwhile, manual inspections are inefficient and have limited coverage. Therefore, the urgent need arises to build an all-weather, blind-spot-free “invisible protective net” that can immediately sound an alarm upon the first sign of foreign-object intrusion, ensuring the safe operation of railways.

Intelligent Intrusion Prevention System for Platform End Zones

The ends of platform platforms connect to the train operating sections and are high-risk areas where passengers are strictly prohibited from entering. However, some passengers, due to a lack of safety awareness or while making phone calls, often inadvertently step over the safety yellow line or even enter the restricted end zones. This not only puts them at significant personal safety risks but can also force trains to stop abruptly, severely disrupting railway transportation order. Traditional methods of physical barriers or manual intervention suffer from issues such as large coverage blind spots, delayed response times, and high labor costs, making it difficult to achieve effective, round-the-clock monitoring and control.

Platform screen door active protection against pinching and foreign objects in gaps

During peak hours on subways and high-speed railways, passengers frequently rush to board and alight, making it highly likely for incidents involving people being caught in platform screen doors to occur. Such incidents can range from minor delays to serious personal injuries. Traditional contact-based safety sensors are “passive protections”—they only trigger a rebound after an object has already been caught, posing injury risks and exhibiting delayed responses. Moreover, some older lines even lack effective anti-pinch mechanisms altogether. The core challenge in ensuring operational safety lies in precisely detecting tiny objects—such as children’s hands or backpack straps—in the final few seconds before the platform screen doors close, and immediately activating braking without any physical contact.

Railway Crossing Hazard Area Availability Notice

Railway level crossings are high-risk areas for off-track safety incidents, where dangerous situations such as pedestrians and vehicles rushing across the tracks and vehicle breakdowns causing delays occur frequently. The traditional “guard + barrier mechanism” model struggles to completely prevent unauthorized intrusions. Meanwhile, video-based monitoring systems are highly susceptible to interference from strong sunlight, nighttime conditions, and rain or fog, leading to detection blind spots and delays. Once an object encroaches onto the track, if the system fails to accurately detect it and issue an alarm within seconds, high-speed trains often won't have enough time to brake, greatly increasing the risk of serious accidents.
