Control device for ground transport vehicle

Abstract

The invention discloses a control device for a ground transport vehicle. The device comprises an ultrasonic automatic following receiving system and an AGV system; the ultrasonic automatic following receiving system is fixed to a ceiling of a needed indoor space, the AGV system can move on the ground of a warehouse, the ultrasonic automatic following receiving system comprises multiple single ultrasonic receiving systems, the AGV system comprises multiple single AGV systems, and the ultrasonic automatic following receiving system can receive signals of ultrasonic sending system ultrasonic sending units in the AGV system. Accordingly, the phenomena of errors caused by wave loss and limitation of a blind area can be avoided, the positioning range of each ultrasonic receiving system is wider,positioning data is more accurate, and the reliability is high; a vehicle-mounted display screen can display the location, speed and local obstacle information in real time; meanwhile, an obstacle avoidance system is adopted, and the error-tolerant rate is increased; the whole system performance is stable, and the running cost and maintenance cost are low.

Description

technical field [0001] The invention belongs to the technical field of control, and in particular relates to a control device for a ground transport vehicle. Background technique [0002] The existing indoor planar motion trolley control system mostly uses the magnetic induction strip attached to the AGV running path to realize positioning and movement through the magnetic induction signal, or paint or paste the ribbon on the AGV running path, and through the camera adopting The input color band image signal is simply processed to realize positioning and movement, and a laser reflector with accurate position is installed around the AGV driving path. The AGV emits a laser beam through a laser scanner and collects the laser beam reflected by the reflector at the same time. To determine its current position and heading, and realize the positioning and movement of the AGV through continuous triangular geometry operations. And all of these have the problem that the route is not ...

AI Technical Summary

Problems solved by technology

Therefore, since the ultrasonic receiving device is fixed on the ceiling, when the angle between the ultrasonic sending system and the ultrasonic receiving device exceeds a certain range, the strength of the ultrasonic signal will decrease rapidly, which will cause wave loss. It can be responded by the ultrasonic receiving device. When it is outside the receiving range, the ultrasonic sent by the ultrasonic sending system cannot be received, resulting in a blind area for ultrasonic reception.
