A kind of AGV traffic control system and control method

Abstract

The invention discloses an AGV traffic control system and a control method, and the system comprises a plurality of AGVs and navigation orbit, the system further comprises a plurality of traffic control landmarks, the traffic control landmark comprises A class landmark, B class landmark and C class landmark, the A class landmark is the priority passage landmark, B class landmark is avoiding control landmark, C class landmark is deregulation control landmark, the control landmark is formed in the traffic control region of the navigation orbit; the AGV comprises the landmark recognition unit, AGV controller and AGV drive unit, the landmark recognition unit receives the traffic control frame sent by the traffic control landmark, the output of the landmark recognition unit is connected to one input of the AGV controller, the output of the AGV controller is connected to the input of the AGV drive unit, the AGV controller gives the corresponding passage occupation right to the AGV according to the traffic control information. The system and the method can effectively solve the competition problem for the AGV while entering into the traffic control region; the impact to the AGV independent traffic control caused by the communication time delay can be reduced.

Description

technical field [0001] The invention relates to the field of automatic guided transport vehicle traffic control, in particular to an AGV automatic traffic control system and a method for performing traffic control on the AGV. Background technique [0002] Automated Guided Vehicle (AGV) is widely used in digital production workshops and assembly workshops. At present, AGV traffic control is mainly: [0003] 1) AGV signals are collected through travel switches and photoelectric sensors, and then the control system sends instructions to the sensors to send signals to control the AGV to achieve traffic control; [0004] 2) Use a PC or industrial computer to form a dedicated AGV controller, and control the operation of the AGV through a wireless network to achieve traffic control; [0005] 3) AGV communicates directly with each other through the wireless network for traffic control. [0006] In method 1, this method has a large amount of engineering, and the control is realized...

Problems solved by technology

[0008] Method 3 is a low-cost and high-efficiency method, but in the currently commonly used traffic control form, the AGV enters the control area at the same time or the impact of communication delay on traffic control is not fully considered.
