Application of Laser Distance Sensors in Carton Warehouse Level Monitoring

2024/9/6

Basic Principle of Laser Distance Sensors

Laser distance sensors work by emitting a laser beam and receiving the reflected signal, measuring the time taken for the laser to travel from emission to reception, and calculating the distance between the sensor and the target object based on the speed of light. This non-contact measurement method maintains high accuracy and stability in various industrial environments. Regardless of the color of the cartons, laser distance sensors are unaffected by light reflection and ambient light, ensuring stable measurements.

The Role of Laser Distance Sensors in Carton Warehouse Level Monitoring

Real-time Level Monitoring:

Based on the direction of the carton warehouse discharge, laser distance sensors can be installed above or in front of the side of the warehouse to measure the stacking height (level) of cartons in real-time. By comparing it with preset thresholds, the system can accurately determine whether the carton stock is sufficient or if it is nearing the storage limit, thereby triggering replenishment or relocation operations in time.

Improving Production Efficiency:

By monitoring material levels in real-time, it is possible to avoid production downtime caused by insufficient stock and prevent excessive stock from occupying storage space. Combined with automated control systems, laser distance sensors can also automatically trigger replenishment or relocation commands, reducing manual intervention and increasing production efficiency.

Ensuring Production Safety:

Laser distance sensors can also monitor the stability of carton stacks, preventing collapse accidents caused by excessively high or tilted stacks. When the sensor detects an abnormal stack, it can immediately issue an alarm, prompting operators to take appropriate measures to ensure production safety.

★ Explanation:
At speed grade 1, “d” represents the actual distance. Under adverse conditions, such as strong sunlight or large fluctuations in ambient temperature, measurement errors may increase. In such cases, using a target reflector improves performance.
