Hydraulic Cylinder Work Area Monitoring and Obstacle Avoidance Solution
Hydraulic Cylinder Work Area Monitoring and Obstacle Avoidance Solution
A hydraulic cylinder is a device that converts hydraulic energy into mechanical energy, primarily used for generating linear motion or force. However, during operation, the extension and retraction of the piston rod can lead to collision accidents, especially when personnel or obstacles are present in the vicinity.
To address this issue, DADISICK’s LD-05D Series 2D LiDAR provides an efficient and reliable solution for area monitoring and obstacle avoidance, ensuring safe equipment operation and minimizing accident risks.
Working Principle of 2D LiDAR
The LD-05D Series 2D LiDAR utilizes the Time of Flight (TOF) principle, emitting laser pulses and measuring the time for the reflected light to return, accurately calculating the distance to the target object. With its high precision, high resolution, and high scanning frequency, it enables real-time monitoring of the surrounding environment and precise obstacle detection.
Area Monitoring & Alarm Function
The LD-05D Series 2D LiDAR supports precise monitoring area configuration with multiple zone groups and monitoring points to ensure real-time detection around hydraulic cylinders.
▪️Flexible Zone Configuration: Supports up to 16 zone groups, each containing 3 sub-zones, allowing customized monitoring and alarm areas.
▪️Real-time Alarms: When an object enters the predefined danger zone, the LiDAR instantly detects it and triggers an alarm signal, notifying the control system to take necessary action.
Obstacle Avoidance Mechanism
Upon detecting an obstacle, the LD-05D Series 2D LiDAR converts the detection data into switching signals, which are then transmitted to the controller. Based on these signals, along with the motion status and preset path of the hydraulic cylinder, the system can:
✅ Immediately stop the hydraulic cylinder’s movement
✅ Adjust movement direction to avoid collisions
This intelligent obstacle avoidance mechanism effectively prevents accidents, reduces equipment damage, and enhances workplace safety.

Real-World Application Case
In an automated production line of a mechanical manufacturing company, hydraulic cylinders drive robotic arms for precision assembly. Since operators work in close proximity to these machines, safety risks are high.
To mitigate this risk, the company installed the LD-05D Series 2D LiDAR at the exit area of the hydraulic-driven equipment to continuously monitor the working zone. When personnel or obstacles enter the danger area, the LiDAR immediately triggers an alarm and stops equipment operation.
Application Results:
✅ Reduced safety incidents by over 70%
✅ Prevented production losses caused by equipment collisions
✅ Enhanced automation safety in the production line
