Millimeter-wave radar sensors are used for forklifts/smart track trolleys to avoid obstacles, and warehouses where forklifts run will encounter staff or various obstacles. If the distance between the fork legs and the obstacle cannot be effectively sensed, accidents such as collisions may occur, resulting in equipment damage and personal injury.
At present, most forklifts use photoelectric switches on the fork feet, which can only provide obstacle/no information for the forklift, and cannot output accurate distance information. The operation of the forklift can only be simply braked, the braking speed cannot be controlled according to the distance from the obstacle, and the operation efficiency is low.
The millimeter-wave radar sensor is used to output distance information at high speed, and the forklift can set different deceleration ranges according to the distance data to improve the operation efficiency of the forklift.
Application environment: In the fork feet, install millimeter wave series single-point radar for forward detection.
The radar detects obstacles in front of the fork feet in real time, providing real-time distance information for the forklift. When an obstacle or a person appears within the warning range in front of the fork feet, the forklift will take deceleration or braking measures according to the distance information to avoid obstacle accidents. Customers can set different deceleration ranges for the forklift according to the running speed of the forklift, for example, no deceleration is required within 5m~10m. Slowly decelerate within 2m~5m. Emergency braking within 2m can effectively improve the operating efficiency of the forklift.
Advantages of millimeter wave radar sensors:
1. Can output distance information.
2. High ranging accuracy.
3. Long range
4. High ranging stability.
5. Small size, easy to install.
The intelligent rail car avoids obstacles, the intelligent rail transmission system connects transmission stations distributed in different areas through specific rails, and the special transport vehicles are transported along the fixed rails to realize three-dimensional transportation between them. In order to improve the working efficiency of rail vehicles, multiple rail vehicles will be running at the same time. In order to prevent multiple vehicles from colliding, a millimeter-wave radar sensor obstacle avoidance solution was introduced to ensure the safe operation of the car and reduce property losses.
1. Suspension rail intelligent robot avoids obstacles:
①.Application introduction:
The intelligent trolley issues distribution instructions through the control center, enters the material distribution point A through the suspended track, and transports it to the station B through the horizontal or vertical track to realize the contactless and rapid transportation of material functions;
②. Millimeter wave radar sensor obstacle avoidance solution:
In the process of orbital form, in order to prevent two or more robots from colliding with each other, two low-cost radar ranging modules are installed on both sides of the robot's head and tail, respectively. When an obstacle is detected during operation, the inspection robot alarm is triggered, and the deceleration/emergency stop is performed to ensure the safe operation of the hanging rail inspection robot.
2.RGV obstacle avoidance:
①.Application:
RGV trolleys can be used in warehouses with various high-density storage methods. The trolley aisle can be designed to any length, which increases the storage capacity of the entire warehouse and makes it safer to operate without a forklift entering the driveway. Taking advantage of the advantage that the forklift does not need to enter the lane, and with the rapid operation of the vehicle on the lane, the operation efficiency of the warehouse can be effectively improved.
②. Millimeter wave radar sensor obstacle avoidance solution:
When the RGV is running on the track, in order to prevent the goods on the shelf from falling, damaging the RGV or hindering the RGV running, two low-cost radar ranging modules are installed on both sides of the head and tail of the RGV to trigger the RGV alarm and detect obstacles during operation. Deceleration/emergency stop when objects are used to ensure the safe operation of the RGV.
