Forklift AGV (Automatic Guided Vehicle) is an automated device used to move goods in warehouses, production lines and other scenarios. In order to ensure the safe operation of forklift AGV, it is very important to achieve collision avoidance and obstacle avoidance functions. The following will introduce how to achieve collision avoidance and obstacle avoidance with forklift AGV from the following aspects.
Forklift AGV (Automatic Guided Vehicle) is an automated device used to move goods in warehouses, production lines and other scenarios. In order to ensure the safe operation of forklift AGV, it is very important to achieve collision avoidance and obstacle avoidance functions. The following will introduce how to achieve collision avoidance and obstacle avoidance with forklift AGV from the following aspects:
Sensor sensing and data acquisition
Forklift AGVs are equipped with a variety of sensors, including liDAR, cameras, ultrasonic sensors, etc., to sense obstacles in the surrounding environment. By sending signals and receiving reflected signals, the sensor obtains information such as distance, shape and position of obstacles, and collects data in real time for subsequent obstacle avoidance processing.
Autonomous positioning and navigation
The forklift AGV determines its position and attitude through the autonomous positioning system, constructs a map using SLAM (Simultaneous Localization and Mapping) technology, and navigates according to the pre-set path. The autonomous positioning system continuously optimizes its position and attitude through data collected by sensors and algorithm processing to ensure that the AGV can accurately navigate and avoid obstacles.
Obstacle avoidance system
Obstacle avoidance system is the core part of forklift AGV to realize collision avoidance and obstacle avoidance. The obstacle avoidance system calculates the obstacle avoidance path in real time through the obstacle information sensed by the sensor, and controls the AGV to carry out corresponding actions. The obstacle avoidance system can adopt a variety of algorithms, such as rule-based algorithm, probabilistic algorithm, machine learning algorithm, etc., and choose the appropriate algorithm to deal with the calculation of obstacle avoidance path according to the actual situation.
Scheduling system and map management
The dispatching system is responsible for managing the task assignment and driving route of the forklift AGV to ensure that the AGV can efficiently complete the handling task. The map management function can update the position and attitude information of the forklift AGV in real time and display it on the map, which is convenient for the dispatcher to monitor and manage the AGV. The combination of dispatching system and map management function can effectively avoid collision and conflict during operation of forklift AGV.
Security monitoring and fault diagnosis
The safety monitoring system can monitor the operating status and surrounding environment of forklift AGV in real time, and alarm and record abnormal conditions. At the same time, the safety monitoring system can also diagnose and warn the AGV fault, discover and deal with the fault in time, and ensure the safe and stable operation of forklift AGV.
In short, forklift AGV collision avoidance and obstacle avoidance rely on a variety of sensors, autonomous positioning and navigation technology, obstacle avoidance system, scheduling system and safety monitoring system to work together. By sensing and autonomous positioning of the surrounding environment, as well as calculation and control of the obstacle avoidance system, forklift AGVs enable safe and efficient handling of cargo. At the same time, reasonable scheduling system and safety monitoring system can effectively reduce the risk of collision and conflict, and improve the operation efficiency of forklift AGV.
