Ensuring the safety of personnel is particularly important in railway transportation operations. Especially during the preparation phase of the train, it is necessary to ensure that all personnel have evacuated the dangerous area near the tracks.

Provide regional protection for the railway tracks and ensure that all personnel evacuate when the train is ready to start. Otherwise, the system will issue an alarm signal. The specific details of the project are summarized as follows:

1. Compatible with height differences:

The system needs to be able to detect people squatting, standing, and individuals of various heights.

2. Continuous monitoring:

Once someone enters the protected area, the system needs to continuously sound an alarm until the personnel evacuate.

3. Detection distance requirements:

The farthest detection distance needs to be at least 15m.

4. Testing accuracy requirements:

Reaching centimeter level within a range of 20m, it can stably detect human arms.

5. Rain and fog resistance:

In outdoor scenes, stable operation is required during light rain weather.

6. High speed data transmission:

Network communication needs to meet data transmission requirements.

7. Multi zone protection function: capable of independently monitoring three zones simultaneously.

We have deployed a railway protection system based on Akusense LiDAR AS-41C for our clients, which can effectively provide safety protection for designated railway areas. When personnel enter dangerous areas, the system will sound an alarm.

The system has the following features and functions:

·High precision distance measurement

Lidar, as an active ranging sensor, calculates the distance between a target object by emitting a laser beam and measuring its echo time. This technology can achieve precise distance measurement and real-time monitoring of railway maintenance areas. High scanning frequency can quickly capture personnel dynamics, ensuring real-time and accurate detection.

Within a range of 20m, the ranging accuracy of LiDAR can reach centimeter level, which can stably detect human arms and meet the requirements of high-precision monitoring.

·Compatible with height differences and continuous monitoring

The laser radar AS-41C can accurately identify individuals of different heights, whether squatting or standing.

Once personnel enter the protected area, the laser radar will immediately activate the alarm mechanism and continue to sound the alarm until personnel evacuate, ensuring the continuity of safety monitoring.

·Remote detection capability

The maximum detection distance of the Meiji LiDAR AS series can reach 100m (depending on the specific model), and the AS-41C with a detection distance of 40 meters can fully meet the requirements for distance detection in this railway protection project.

·Rain and fog resistance ability

In light rain weather, the LiDAR can still work continuously and stably, providing stable perception data for vehicles. Lidar actively emits light (GB7247.1-2012, eye safety), with a longer line of sight and emitting invisible light that does not cause light distortion to the human eye.

AS-41C uses dynamic echo energy filtering method to determine whether there is rainwater intrusion, filters out nearby echoes, and greatly reduces the influence of water droplets on the light in the window. At the same time, a lot of optimization has been made in the structure to minimize the residual rainwater on the surface as much as possible.

·High speed data transmission

Lidar supports network port communication, which can meet the requirements of high-speed data transmission and ensure the real-time and accuracy of monitoring data.

·Multi zone protection function

The system supports independent monitoring of three areas simultaneously, and each area can be configured with an independent alarm mechanism to ensure the comprehensiveness and flexibility of railway protection.

Akusense laser radar railway protection system has been successfully applied in multiple railway projects across the country, effectively improving the safety of railway maintenance personnel.

When the train is ready to start, the system can accurately identify and alert personnel entering the protected area, ensuring that all personnel evacuate in a timely manner. At the same time, the system's high precision, long-distance detection capability, rain and fog resistance, and multi area protection function provide comprehensive protection for railway protection.
