AGV (automatic guided vehicle) traffic automatic control system and AGV traffic automatic control method

Abstract

The invention discloses an AGV (automatic guided vehicle) traffic automatic control system and an AGV traffic automatic control method. The AGV traffic automatic control system comprises a navigation track and an AGV which runs on the navigation track, wherein an AGV drive unit is mounted on the AGV; a traffic control region is mounted on the navigation track; a wireless control unit is also arranged on the AGV; the wireless control unit is electrically connected with the AGV drive unit; and an information trigger device for opening and closing the wireless control unit on the AGV is arranged in the traffic control region. According to the AGV traffic automatic control system, the AGV automatic traffic control is realized based on a wireless communication technology, the project amount of traffic control construction is reduced, the hardware cost is lowered, wireless communication among AGVs is realized and traffic collision accidents are avoided; the whole and local influences in the traffic control are separated, and the territorial limitation in the traffic control is removed; the stability of the traffic control is improved, so that the traffic control is not easily interfered; and a wireless communication address code needs to be consistent with that of the AGV system, and if a conflict is existent, an internal address code of the AGV system and a corresponding channel of a wireless module are changed.

Description

technical field [0001] The invention relates to an AGV traffic automatic control system and a control method thereof. Background technique [0002] Automated Guided Vehicle (AGV for short), refers to a transport vehicle equipped with automatic guidance devices such as electromagnetic or optical, capable of driving along a prescribed guiding path, with safety protection and various transfer functions, in industrial applications A truck that does not require a driver uses a rechargeable battery as its power source. [0003] At present, the known AGV traffic control method is to collect AGV signals through travel switches and photoelectric sensors, and then send instructions to the sensors through the control system to send signals to control the AGV to achieve traffic control; however, the above-mentioned traditional AGV traffic control methods have the following shortcomings Advantages: (1) This method has a large amount of engineering and is controlled by wired methods, and...

[0003] At present, the known AGV traffic control method is to collect AGV signals through travel switches and photoelectric sensors, and then send instructions to the sensors through the control system to send signals to control the AGV to achieve traffic control; however, the above-mentioned traditional AGV traffic control methods have the following shortcomings Advantages: (1) This method requires a large amount of engineering and is controlled by wired methods, and the AGVs cannot communicate with each other; moreover, this method has requirements for the area of ​​traffic control, and the hardware cost is also high; (2) It The dispatching system is used to dispatch the operation of the AGV; the disadvantage of this method is that when there is a problem with the dispatching system, the dispatching system is paralyzed; traffic accidents will occur when the AGV passes the intersection; and the hardware cost of setting up the dispatching system is quite high
