The detection principle of AGV unmanned vehicle obstacles: using ultrasonic method to measure distance, obtain quantitative interval information, and then use the quantized interval information as a reference for speed control of AGV. Generally, obstacles are close to detection equipment. Within a certain interval, the AGV travels at a reduced speed, and within a closer interval, the AGV trolley is aborted, and when the obstacle is removed, the AGV will automatically resume normal travel.

The obstacle detection methods used by the existing AGVs on the market are discriminated by the output I/O status of the obstacle monitoring equipment, that is, the method can only determine whether there is an output signal/no output signal when the method is detected/accessible. Object, but can not quantify the obstacle interval. And once an obstacle is detected, the AGV control system will immediately park, so if the AGV operation is at a higher speed, there will be a risk of immediate suspension due to inertia in the movement of the items on the trolley and the trolley.

AGV unmanned vehicle obstacle detection method: obstacle detection equipment, which includes ultrasonic sensing module, ranging module and AGV speed regulating module; ultrasonic sensing module for transmitting and receiving ultrasonic signals; ranging module, The ultrasonic signal is processed and converted into quantized interval information and output to the AGV speed control module; the AGV speed control module is configured to adjust the travel speed of the AGV according to the quantization interval information output by the ranging control unit to reduce the inertia. , slow parking.

Convenient robot AGV trolley obstacle detection includes speed exploration, load exploration, and other optical vision sensing and ultrasonic sensors are used to explore the vehicle spacing. Multiple obstacle detection maximizes the safety of the AGV in use.
