Passive vision navigation unmanned forklift system for explosion-proof warehouse and navigation method

Abstract

The invention discloses a passive vision navigation unmanned forklift system for an explosion-proof warehouse. The passive vision navigation unmanned forklift system comprises a forklift body, a dispatching device, an explosion-proof camera, an explosion-proof controller, an inductor, an alarm and a mechanical anti-collision device. The real-time position of a forklift is determined by processingand analyzing the real-time beacon information of the forklift and stored corresponding beacon information, and the optimal path selection is continuously carried out on a path until the target position is reached during the traveling. The passive vision navigation unmanned forklift system realizes unmanned operation of passive visual navigation in the explosion-proof warehouse, endangering of human health is avoided, the manpower investment is reduced, the operation efficiency is improved, and working time is shortened.

Description

technical field [0001] The invention relates to the technical field of unmanned vehicles, in particular to an unmanned forklift system and navigation method for explosion-proof warehouses, which can perform autonomous positioning, navigation and obstacle avoidance in combination with environmental information. Background technique [0002] Explosion-proof standards divide the nature of explosives into: Class I, mainly methane (underground mine environment); Class II, explosive gases and mixtures (gas environment); Class III, combustible dust (dust environment). On this basis, the levels are divided according to the frequency, duration and danger of explosive mixtures in explosion-proof warehouses: A, Zone 2, Zone 1 and Zone 0 of explosive gas atmospheres, from left to right, explosive mixtures appear The more frequent, the longer the duration; B, Zone 22, 21, and 20 in the combustible dust environment, from left to right, the more frequent the explosive mixture appears, the ...

AI Technical Summary

Problems solved by technology

[0003] Although the danger of explosion-proof warehouses is so high, the current explosion-proof warehouses are still in the original manual operation stage, and there are problems such as high labor costs, low efficiency, and hazards to human health. Unmanned forklifts can solve the problems in the handling process to a certain extent. Manual problems in the process, reduce manpower input, and improve work efficiency
