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...

Examples

Embodiment 1

[0023] Embodiment one: if Figure 1 to Figure 3 As shown, the AGV automatic traffic control system includes a navigation track 4 and an AGV 1 traveling on the navigation track 4, the AGV 1 is equipped with an AGV drive unit, and the navigation track 4 is provided with a traffic control area 5. The AGV 1 is also provided with a wireless control unit, which is electrically connected to the AGV drive unit; a trigger information device 2 including opening and closing the AGV wireless control unit is installed in the traffic control area 5 .

[0024] The trigger information device 2 is an RFID card or a magnetic strip road sign; the wireless control unit is mainly composed of a wireless receiving module, a wireless sending module and a main control MCU.

[0025] The navigation track 4 is provided with an intersection 3 formed by connecting two (or more) tracks to each other. The intersection 3 is located in the center of the traffic control area 5. When entering or leaving the bord...

Embodiment 2

[0034] Embodiment two: if Figure 5 As shown, this embodiment is similar to Embodiment 1, and the only difference is that an AGV temporary stop 8 is set on the navigation track 4, and the AGV temporary stop 8 is located in the traffic control area 5, and when entering or leaving the traffic A trigger information device 2 is arranged on the side of the track at the boundary of the control area 5, which avoids the occurrence of rear-end collision accidents. The AGV temporary stop 8 is located in the center of the traffic control area 5 .
