Smart Rail-Guided Vehicles obstacle avoidance

The smart rail-guided transmission system connects the transmission stations distributed in different areas through specific track connections. The customized carriages transport along fixed tracks to achieve the 3-dimentional point-to-point transportation between these stations. In order to improve the working efficiency of the track car, there will be multiple track cars running at the same time. In order to prevent the collision of multiple cars, BENEWAKE launched the "BENEWAKE lidar obstacle avoidance program" to provide security for the safe operation of the car and reduce property losses.

1、Smart hanging rail robots obstacle avoidance

The control center issues a distribution instruction, and the smart vehicle travels to the material distribution point A through the hanging rail, and transports to the station B through the horizontal or vertical track, thereby realizing the non-contact and rapid transportation of the materials.

In order to prevent two or more robots from colliding with each other during transportation, two pieces of TF-Luna low cost distance sensor or CE30-A 3D obstacle-avoidance LiDAR are installed on both sides of the head and tail of the robot to detect distances, as shown in Figure 1. When an obstacle is detected, the inspection alarm is triggered, and deceleration or emergency stop is performed to ensure the safe operation of the hanging rail inspection robots.

2、Roadway stacker obstacle avoidance

Roadway stacker refers to a special crane that uses forks or skewers as picking devices to pick and place single cargo from a high-level shelf or to pick, transport and stack in the warehouse or workshop.

During the roadway stacker transporting, two pieces of TF-Luna low cost distance sensor are installed on both sides of the head and tail of the stacker to detect distance, in order to prevent the goods on the shelf from falling to hurt the stacker or block the roadway, as shown in Figure 2. When an obstacle is detected, the inspection alarm is triggered, and deceleration or emergency stop is performed to ensure the safe operation of the roadway stacker.

3、RGV obstacle avoidance

RGV can be used in various high-density storage warehouses. The rail passage can be designed as any length, which can increase the storage capacity of the entire warehouse; and in this way, the forklift is not required to drive into the roadway during operation, which makes the operation safer. By taking this advantage and cooperating with the rapid operation of the vehicle in the roadway, the operation efficiency of the warehouse can be effectively improved.

During the RGV driving on the rail, two pieces of TF-Luna low cost distance sensor are installed on each side of the RGV head and tail to detect distances, in order to prevent the goods on the shelf from falling to hurt the RGV or block the roadway, as shown in Figure 3. When an obstacle is detected, the inspection alarm is triggered, and deceleration or emergency stop is performed to ensure the safe operation of the RGV.
