Problems solved by technology

Due to the relatively large inertia of the transported AGV car, when an obstacle is detected in front of it, it will stop directly, and it may hit the object in front of it.
And because the AGV car generally travels a short path, it will have a greater negative impact on the execution efficiency and time of the car

Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] Such as figure 1 As shown, the present invention is an AGV car based on laser navigation and laser scanning, including a laser scanning global positioning sensor 1, a laser radar scanner 3, a car body 7, and a Hall electromagnetic sensor 2. In order to assist, the laser scanning global positioning sensor is also used. A Hall electromagnetic sensor 2 is added below. The laser scanning global positioning sensor is installed on the sensor bracket 4 at the front of the car, which can accurately obtain the coordinates of the car, position the car, and add the time of the upper computer system to obtain the three-dimensio...

Abstract

The invention discloses an intelligent obstacle-avoiding AGV (Automatic Guided Vehicle) system and obstacle-avoiding method. The intelligent obstacle-avoiding AGV system comprises an AGV, a Hall electromagnetic sensor, a laser scanning radar, a Bluetooth module and an upper computer, wherein the Hall electromagnetic sensor is arranged on the lower part of the front end of the front surface of the AGV body; the laser scanning radar is arranged on the upper part of the body of the AGV; and an MCU (Microprogrammed Control Unit) master control module of the AGV communicates with the upper computer through the Bluetooth module. The AGV system is simple in structure and is high in cost performance. The obstacle-avoiding method based on the AGV system improves vehicle operation efficiency through the intelligent control on the vehicle by the system, and greatly reduces the possibility that the vehicle has an accident; and moreover, the laser scanning radar is wide in range and is long in distance, so that adaption of the AGV is greatly strengthened.

Description

technical field [0001] The invention relates to intelligent logistics equipment technology, in particular to an intelligent obstacle avoidance AGV (Automated Guided Vehicle) trolley system and an obstacle avoidance method. Background technique [0002] The existing AGV obstacle avoidance equipment mostly uses photoelectric circuits or ultrasonic waves, which can only judge whether there is an obstacle in front of it in a short distance and in a small range, and then stop the vehicle. For slow speed situations, this obstacle avoidance solution can Meet the needs. However, with the continuous development of technology, the speed of AGV cars is constantly increasing. Due to the relatively large inertia of the transported AGV car, when an obstacle is detected in front, it will stop directly, and it may hit the object in front. And because the AGV car generally travels a short path, it will have a greater negative impact on the execution efficiency and time of the car. Conten...
