Millimeter wave radar module module tunnel foreign body intrusion monitoring scheme, tunnel is one of the road sections with frequent traffic accidents. Restricted by geographical conditions, there are many bends in the tunnel, the bends are large, the bends are urgent, and the lighting conditions are limited. When encountering falling rocks, intruding people or livestock, it will greatly affect driving safety. At present, railway tunnels and highway tunnel systems mainly use various monitoring methods to determine whether there is foreign body intrusion and disaster prevention alarms. Provide passengers with safe, stable and healthy travel services.

Millimeter wave radar module module tunnel foreign body intrusion monitoring scheme

The tunnel intrusion monitoring system takes the long-distance millimeter wave radar module module as the core sensor, and monitors the tunnel in real-time around the clock in harsh environments. Monitor the traffic flow in the tunnel, accurately and quickly determine the size and location information of obstacles, and issue alarm signals in time to minimize safety risks.


1. Application introduction


1. Zone setting


Use the millimeter wave radar module to set the tunnel monitoring range. The range of the millimeter wave radar module module can reach more than 50 meters, which is suitable for long tunnel environments with dark and no ambient light. At the same time, the viewing angle is wide, and the high-definition density point cloud can accurately restore the three-dimensional image information in the tunnel, so as to accurately set the defense zone. For example, for railway tunnels, a standard zone of 1875mm wide can be set along the center of the track to accommodate curves and up and down gradients. Accurate zone settings allow the system to monitor obstacles within the zone and not be triggered by beacons or other targets outside the zone.


2. Trigger the alarm


The millimeter wave radar module module alarms the obstacles in the prevention area according to the alarm logic. Even distant obstacles can accurately detect the location and size of the obstacle. After the target is detected, it is judged that the obstacle is indeed in the defense area, larger than the set alarm size, and an alarm signal is triggered. For example, the tunnel foreign body intrusion solution can detect vehicles, pedestrians, and even 20cm*20cm*20cm obstacles based on the monitored point cloud data, trigger sound and light alarms, and output alarm signals.


3. Function upgrade

The foreign body intrusion solution based on the millimeter wave radar module module can further upgrade the functions, such as:

①. The solution can be equipped with a camera ball machine to carry out lightning ball linkage to capture or record video, which is convenient to further confirm the danger of intrusion and improve the alarm record.

②. This solution can be combined with artificial intelligence algorithms to set non-obstacle information and cache non-obstacle features, thereby eliminating normal moving targets in some defense zones and reducing virtual alarms.

③. The scheme should also include client user interface, system log, communication protocol, etc. to facilitate system integration.

Second, the application advantages.

1. No false negatives, low false negative rate: large viewing angle, suitable for covering wide tunnel scenarios. High-definition density 3D point clouds and intelligent AI algorithms improve the accuracy of obstacle detection and identification.

2. Reliable, all-weather automatic monitoring: The millimeter wave radar module module products have passed the national standard earthquake resistance, EMI, human eye safety and other tests, and passed the third-party test in the rail transit industry. Reliable, all-day work, unaffected by harsh environments and light.

3. All-round, no dead angle coverage: 100-meter long-distance detection, long detection distances can be reserved for tunnel straights, curves, and fork roads, to reserve response time for vehicle braking.

4. Intelligent judgment and alarm: When the vehicle enters the monitoring area, it can generate valid data. As long as the intelligent algorithm is matched, the interference of moving objects such as vehicles and pedestrians to the system can be effectively filtered. Linked cameras can be afraid to upload images and generate alarms and inspection information in real time.

5. Convenient construction and short cycle: The millimeter wave radar module module non-contact monitoring system can deploy existing infrastructure, and the construction is fast and does not affect driving.

6. Support secondary development: The origin cloud data is completely open, and the supporting algorithm software and SDK are also open to customers, which can be integrated with other sensors, support customers to customize more practical functions, and achieve long-term benefits.
