Problems solved by technology

[0004] Generally, unmanned forklifts can only perform point-to-point handling (the smallest storage unit in the warehouse), so the upper system needs to issue specific pick-up points and release points, while the upper-level system does not issue specific pick-up points and drop-off points. In the case of the cargo point, the cargo handling cannot be carried out.

Embodiment 1

[0052] Example 1: The pick-up point is an area, and the delivery point is an area

[0053] The pick-up point is configured in the area, and the cargo sensing device at the pick-up point senses the arrival of the goods and notifies the on-board control system of the unmanned forklift of the location of the goods. The on-board control system of the unmanned forklift queries the location management information and performs routing planning. Specifically, the on-board control system of the unmanned forklift first obtains the configured delivery point area through the routing information management interface; The status of the bit includes: free, occupied and disabled, and the corresponding executable operations include: reserve, release, and enable; finally, the location of the delivery is determined according to the location and status of each storage location.

Embodiment 2

[0054] Embodiment 2: The pick-up point is an area, and the delivery point is a channel

[0055] When the pick-up point is configured in an area and the drop-off point is configured as a channel, the cargo sensing device at the pick-up point senses the arrival of the goods and notifies the on-board control system of the unmanned forklift of the location of the goods, and the on-board control system of the unmanned forklift queries the location management information and proceeds route planning. The difference from Embodiment 1 is that the vehicle-mounted control system of the unmanned forklift first obtains the configured delivery point channels through the routing information management interface; then directly obtains each storage location and its status of the delivery point channels according to the location management information That's it; finally, determine the delivery location according to the location and status of each storage location.

Embodiment 3

[0056] Embodiment 3: The pick-up point is the channel, and the delivery point is the area

[0057] When the pick-up point is configured as an aisle and the drop-off point is configured as an area, the cargo sensing device at the pick-up point senses the arrival of the goods and notifies the on-board control system of the unmanned forklift about the location of the goods, and the on-board control system of the unmanned forklift queries the location management information and proceeds Routing planning; in addition, after the goods sensing device at the pick-up point senses the arrival of the goods, it can only notify the on-board control system of the unmanned forklift that there are goods waiting to be picked up in this channel. The sensor device (for example: photoelectric sensor) of the human forklift itself determines the location of the goods according to the data of the sensor device, and then the on-board control system of the unmanned forklift queries the location managem...

Abstract

The invention discloses an unmanned forklift route planning method and device, and relates to the technical field of computers. One specific embodiment of the method comprises the steps that an unmanned forklift generates a carrying instruction according to the goods position sent by a goods sensing device at a goods taking point; according to the carrying instruction, the unmanned forklift periodically obtains the state of a set goods placing point and carries out route planning according to the current position of the unmanned forklift and the state of the goods placing point, and the goodsplacing point comprises a plurality of goods placing positions. According to the embodiment, routing planning can be carried out by the vehicle-mounted control system of the unmanned forklift withoutdepending on the specific goods placing position issued by an upper system, the forklift can be dispatched more flexibly and conveniently, the warehouse-in and warehouse-out and warehouse-moving efficiency is higher, meanwhile, the routing planning result is better, unnecessary warehouse-moving operation is saved, and the labor intensity of workers is reduced. Storage rate of the warehouse is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for route planning of an unmanned forklift. Background technique [0002] At present, the unmanned forklifts on the market are generally used in the handling scene. For the handling tasks issued by the business system, in the handling area, the unmanned forklifts perform: receive the handling order -> arrive at the pick-up point -> pick up the goods -> arrive at the delivery area Cargo point —> the handling process of releasing the goods. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] Generally, unmanned forklifts can only perform point-to-point handling (the smallest storage unit in the warehouse), so the upper system needs to issue specific pick-up points and release points, while the upper-level system does not issue specific pick-up point...
