Abstract

The invention discloses a station identification system based on an AGV and a control method thereof.The system comprises a guide rail, a station identification and a central control interaction device, wherein the station identification is arranged on a corresponding station, an AGV body runs between different working regions along the guide rail under the control of the central control interaction device, and when the AGV body travels to the position of the station identification, an infrared probe making contact with a starting mark line in a station identification unit transmits a signal to a core board through an infrared level switching board, and the core board conducts low-signal timing on all the infrared probes; the time difference of the infrared probes making contact with a buffer mark line is recorded and offset; signal change and retention time of the infrared probes passing through the buffer mark line, a road section mark belt and a character string code value in sequence are recorded, decoding is conducted to obtain the number of character strings and corresponding station information, and the information is displayed on a human-computer interaction interface of the central control interaction device.The system is reasonable in design, economical, efficient, and capable of improving automation level and production efficiency.

Description

technical field [0001] The invention relates to a technology in the field of robot identification and control, in particular to an AGV-based station identification system and a control method thereof. Background technique [0002] Automated Guided Vehicle (AGV) is a type of wheeled robot, which is usually used by modern factories to carry materials and identify work stations, and it can guide along a specified path. Guidance forms can be divided into optical guidance and magnetoelectric guidance. The former's track is guided by a track with a different color from the ground, and the latter is guided by an electromagnetic track. The computer can send real-time work instructions to the AGV. [0003] After searching the prior art, it was found that Chinese Patent Document No. CN102854878A, published on January 2, 2013, discloses an infrared photoelectric guiding AGV device and its control method. A driven wheel is installed at each of the four end corners of the bottom of the ...
