Laser displacement sensing technology plays a significant role in the positioning and application within intelligent automated storage and retrieval systems (AS/RS). Details are as follows:

Positioning Aspects

- Goods Storage Location Positioning: By installing laser displacement sensors at various locations on the shelves, the distance between the goods and the sensor can be precisely measured, thus determining the specific location of the goods on the shelves. This positioning method offers high accuracy, enabling precise location of goods, facilitating accurate recording and tracking of goods storage locations by the warehouse management system, and improving the accuracy and efficiency of inventory management.
- Equipment Operating Position Positioning: For various equipment in intelligent AS/RS, such as stacker cranes and shuttle cars, laser displacement sensing technology can monitor their operating positions in real-time. By installing sensors at key parts of the equipment or on the running track, the position change of the equipment relative to the reference point can be accurately measured, ensuring the accuracy and stability of the equipment during operation, preventing accidents such as equipment collisions and derailment, and ensuring the normal operation of the AS/RS.
- Personnel Positioning Assistance: In some large intelligent AS/RS, to ensure personnel safety and work convenience, laser displacement sensing technology can also be used for personnel positioning assistance. By installing sensors at appropriate locations in the warehouse, combined with other positioning technologies, real-time location information of personnel within the warehouse can be obtained, allowing management personnel to grasp personnel dynamics in a timely manner and respond quickly in emergencies, ensuring personnel safety.

Application Aspects

- Inbound Process
- Goods Dimension Measurement: Before goods enter the warehouse, laser displacement sensors can quickly and accurately measure the dimensions of the goods, including length, width, and height, providing accurate data support for goods storage allocation. The system automatically selects the appropriate shelf location and storage method based on the measurement results, improving the utilization rate of warehouse space and avoiding storage difficulties or space waste due to inconsistent goods dimensions.
- Goods Posture Detection: In addition to dimension measurement, laser displacement sensors can also detect the posture of goods to ensure that the goods are placed according to requirements upon entry. For example, for goods with specific directional requirements, the sensor can detect whether they are placed in the specified direction. If the posture is incorrect, an alarm can be issued promptly, prompting personnel to make adjustments, ensuring the standardization and safety of goods storage.

- Storage Process
- Shelf Deformation Monitoring: The shelves of an intelligent AS/RS may undergo slight deformation under long-term load. Laser displacement sensors can monitor shelf deformation in real-time. By measuring the displacement changes at key parts of the shelves, potential safety hazards can be detected promptly. Once the deformation exceeds the set threshold, the system will immediately issue an alarm, reminding management personnel to take measures such as adjusting the shelf structure or reinforcing the shelves to prevent accidents such as shelf collapse and ensure the safety of goods storage.
- Inventory Check: Automated inventory checks can be achieved using laser displacement sensing technology. By installing sensors on the shelves, goods are scanned and measured periodically or irregularly to obtain the actual storage location and quantity information of the goods, and compared with the data in the inventory management system. This inventory method is fast and accurate, greatly reducing the workload and error rate of manual inventory checks, and improving the real-time and accuracy of inventory management.

- Outbound Process
- Goods Retrieval Positioning: When there is an outbound task, laser displacement sensors can help equipment accurately locate the goods to be retrieved. Stacker cranes or other handling equipment, based on the position information provided by the sensor, can quickly and accurately reach the location of the goods, improving the efficiency and accuracy of outbound operations, and reducing the time and labor costs of searching for goods.
- Packaging Integrity Detection: Before goods are shipped out, laser displacement sensors can also detect the integrity of the goods' packaging. By measuring the flatness of the packaging surface and the presence of any damage, it is determined whether the packaging meets transportation requirements. If

packaging problems are found, they can be processed or the packaging can be replaced in a timely manner to ensure the safety and integrity of the goods during transportation.

Laser displacement sensing technology plays a crucial role in intelligent AS/RS. From precise positioning to applications in various processes, it effectively improves the operational efficiency, safety, and management level of AS/RS, driving the warehousing industry towards greater intelligence.
