[0002] At present, in the forklift battery replacement operation process, although the battery is efficiently replaced to maintain the forklift's ability to operate continuously, its safety issues cannot be ignored at the actual operation level. Specifically, when the forklift driver drives the forklift into the forklift battery replacement yard for battery replacement, this process itself places strict requirements on time management and space planning. However, in actual scenarios, the entry and exit areas of the forklift battery replacement yard are often also areas with frequent personnel flow, including but not limited to forklift drivers, battery replacement operators, maintenance personnel, and possible visitors or cargo handlers.
