Abstract

The invention discloses an automatic guidance carrying forklift protection system. The automatic guidance carrying forklift protection system comprises a primary detection device, a secondary detection device and a control device, wherein the primary detection device is used for detecting obstacle information in a first preset distance; the second detection device is used for detecting obstacle information in a second preset distance, and the second preset distance is smaller than the first preset distance; and the control device is used for controlling an automatic guidance carrying forkliftto stop operating when detecting a detection signal of the secondary detection device and not detecting a detection signal of the primary detection device. The automatic guidance carrying forklift protection system can provide multiple protection functions, and safety is improved. The invention further discloses the automatic guidance carrying forklift and a protection method of the automatic guidance carrying forklift.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to an automatic guided transport forklift protection system, an automatic guided transport forklift including the automatic guided transport forklift protection system and a protection method thereof. Background technique [0002] AGV (Automated Guided Vehicle, automatic guided handling forklift), under the computer monitoring, according to the path planning and operation requirements, accurately execute and stop at the designated place, complete a series of operation functions, with safety protection and various transfer functions.
