Summary
Unveiling Safety LiDAR: Learn how Safety Laser Scanners safeguard industrial spaces. Explore their technology, benefits, and real-world uses with Dadisick's cutting-edge solutions.
Introduction to Safety LiDAR
Safety LiDAR, commonly known as a Safety Laser Scanner, is a cutting-edge technology designed to enhance workplace safety by detecting potential hazards and preventing accidents. These advanced LiDAR safety scanner use laser beams to monitor predefined areas, ensuring the safety of personnel and equipment in industrial environments. At Dadisick, we specialize in delivering reliable Safety LiDAR solutions that integrate seamlessly into various applications, from factory floors to automated guided vehicles (AGVs).
What is a Safety Laser Scanner?
A Safety Laser Scanner is an optoelectronic device that employs laser technology to detect objects, people, or obstacles within a specified zone. Unlike traditional safety devices, these scanners offer non-contact, high-precision monitoring over a wide area, making them indispensable in modern industrial safety systems. When an intrusion is detected, the scanner triggers a safety response—such as stopping machinery or issuing an alert—to mitigate risks.
How Does a LiDAR Safety Sensor Work?
Safety Laser Scanners operate on the Time-of-Flight (TOF) principle. Safety LiDAR scanners use infrared lasers to detect people or objects within their scanning range. The scanners emit laser beams in a fan shape at slightly different angles, allowing them to calculate the distance to detected objects and determine their location within warning or protective zones. Unlike traditional motion detectors, Safety LiDAR does not rely on movement detection alone. Instead, it continuously monitors the protected area and triggers alarms or stops machinery when an intrusion is detected. Here’s a step-by-step breakdown of their functionality:
1. Laser Emission: The scanner emits laser pulses in a two-dimensional plane, typically covering a wide scanning angle (e.g., 270°).
2. Reflection Detection: When the laser beam encounters an object, it reflects back to the scanner’s receiver.
3. Distance Calculation: The scanner measures the time taken for the laser to return, calculating the distance to the object using the speed of light.
4. Zone Monitoring: Predefined safety zones (e.g., warning and danger zones) are monitored. If an object enters these zones, the scanner initiates a programmed response.
For example, Dadisick’s Safety LiDAR products, like the LD-05D Series, use a 905 nm laser source with a scanning frequency of 15 Hz and an angular resolution of 0.1°, ensuring precise detection up to 5 meters.
Key Features of Safety Laser Scanners
Safety Laser Scanners offer a range of features that make them ideal for industrial safety:
● High Precision
Detects objects with accuracy down to ±3 mm (e.g., Dadisick LD-05D Series).● Wide Scanning Range
Safety LiDAR scanners offer a wide-angle monitoring area, covers up to 270°, with customizable detection zones (e.g., Dadisick LD-20D Series offers a 20-meter range).Fast Response Time: Reacts within milliseconds to intrusions (e.g., 66 ms default for Dadisick LD-20D at 30 Hz).
● Customizable Zones
Supports multiple configurable safety zones for tailored protection. DADISICK’s laser scanning LiDAR can be programmed to have multiple levels of protection, including primary protection zones and warning zones, allowing for flexible and customizable safety setups.● Durability
Built to withstand harsh environments. Advanced models come with features to filter out dust and dirt, ensuring reliable operation in challenging environmental conditions.Muting Functions: Some models offer muting functions that allow the temporary disabling of safety functions in specific scenarios, such as the presence of non-hazardous objects.
Applications of LiDAR Safety Scanner
Safety Laser Scanners are versatile tools used across various industries:
● Industrial Automation: In automated guided vehicle (AGV) applications, Safety LiDAR scanners provide 360-degree coverage around the vehicle, ensuring safe operation in dynamic environments where personnel and other machinery may be present. Protects workers near robotic arms and machinery by halting operations when personnel enter danger zones.
● AGV Navigation: Ensures safe movement of automated guided vehicles by detecting obstacles (e.g., Dadisick LD-20D slows or stops AGVs based on zone intrusion).
● Access Control: These scanners are ideal for monitoring hazardous areas in manufacturing facilities, where they can detect the presence of personnel and trigger emergency stops to prevent accidents.
● Factory Safety: Detects protrusions on shelves or conveyor belts to prevent accidents.
● Mobile Applications: Safety LiDAR is particularly useful in mobile applications, offering a cleaner and less cumbersome alternative to traditional sensor setups.
● Robot Cells: Safety LiDAR can replace traditional safety gates or light curtains around robot cells, reducing costs and setup time while providing comprehensive protection.
