With the development of intelligent warehousing and industrial logistics, unmanned forklifts have become the core equipment of the scene with the advantage of automated operation, and their safety protection system is the key to ensuring the stability of the operation. We will dismantle the operating logic of this system from multiple dimensions to demonstrate its comprehensive safety protection capabilities.
Front-end perception early warning protection
As the first line of defense for safety protection, the front-end sensing system realizes global environmental monitoring through multi-device collaboration. Lidar can scan the operation area in real time to accurately identify the position and movement trajectory of obstacles. When the distance is detected to enter the warning threshold, the system immediately triggers a sound and light warning to inform the surrounding personnel and equipment in advance. At the same time, the visual recognition module can capture information such as personnel characteristics and goods status, identify personnel who enter the operation area illegally or abnormally stacked goods, and further complete the blind spot of radar perception.
Active intervention and brake protection
When the front end senses a risk, the system activates an active intervention mechanism. According to the distance and moving speed of the obstacle, the system automatically adjusts the speed of the forklift, from deceleration to low-speed cruise, to avoid collisions caused by excessive speed. If the risk level reaches the threshold, the emergency braking system will start quickly. Through the coordination of hydraulic and electronic braking, the forklift will stop smoothly within the shortest distance, and at the same time cut off the power output to prevent secondary risks.
Human-machine interaction and area protection
In order to adapt to the mixed operation scenario of manned and unmanned, the system has set up a complete human-machine interaction protection logic. When the operator approaches or takes over the forklift, the system automatically switches to manual mode to ensure the safe transfer of operation authority. In addition, the regional authority control function can divide the operation restricted area and the safe area. Before the unmanned forklift enters the restricted area, it will automatically trigger an early warning and stop moving to prevent entering the high-risk area.
This multi-security protection system builds a safety barrier covering the entire process of the operation through layers of perception, intervention, and interaction, providing a reliable guarantee for the efficient operation of industrial logistics scenarios.
