Abstract

A method and an electronic device for handling a material are provided. The method may include: obtaining a picking task for a target material at a target warehouse; using, in response to determining that a target person arrives at an exit location of the target warehouse, material information of a material held by the target person as target material information, the material information including a material identifier and a material quantity; and comparing material information of a to-be-picked material in the picking task with the target material information, and subtracting the material information of the to-be-picked material from stock information of the target warehouse if a comparison result is that the material information and the target material information are consistent.

First claim

1 . A method for handling a material, used for a control apparatus, the method comprising:
obtaining a picking task for a target material at a target warehouse; using, in response to determining that a target person arrives at an exit location of the target warehouse, material information of a material held by the target person as target material information, the material information comprising a material identifier and a material quantity; and comparing material information of a to-be-picked material in the picking task with the target material information, and subtracting the material information of the to-be-picked material from stock information of the target warehouse if a comparison result is that the material information and the target material information are consistent.

2 . The method according to claim 1 , wherein the using the material information of the material held by the target person as the target material information comprises:
determining, when a weight of the target material is within a preset weight range, change material information fed back with respect to a weight-changed target storage location by a target gravity shelf receiving a weight change in the target warehouse as the target material information, wherein the preset weight range respectively takes a first weight value and a second weight value as a weight lower limit value and a weight upper limit value.

3 . The method according to claim 2 , wherein before the material information of the material held by the target person is used as the target material information, the method further comprises:
acquiring, in response to the gravity shelf of the target storage location where the target material is receiving a weight change, a change material identifier and change material quantity determined by the gravity shelf for the target storage location, when the weight of the target material is within the preset weight range; and using the change material identifier and change material quantity as the change material information.

4 . The method according to claim 3 , further comprising:
acquiring at least two material images collected by a camera for the target storage location, wherein the at least two material images are material images collected from a first moment prior to a weight change moment to a second moment subsequent to the weight change moment, and the camera collecting the at least two material images is used to photograph a material at the target storage location or at the gravity shelf having the target storage location, wherein the using the change material identifier and change material quantity as the change material information comprises:
using the change material identifier and change material quantity as the change material information, in response to determining that a changed material identifier indicated by a recognition result of the at least two material images is the change material identifier.

5 . The method according to claim 4 , further comprising:
sending, in response to determining that the changed material identifier indicated by the recognition result of the at least two material images is not the change material identifier, alarm information to an alarm device to cause the alarm device to given an alarm, wherein the alarm device is a voice alarm device, or an electronic tag corresponding to the target storage location.

6 . The method according to claim 1 , wherein the subtracting the material information of the to-be-picked material from stock information of the target warehouse if a comparison result is that the material information and the target material information are consistent comprises:
sending, if the comparison result is that the material information and the target material information are consistent, an open instruction to a stock-out turnstile at the exit location, and subtracting the material information of the to-be-picked material from the stock information.

7 . The method according to claim 6 , further comprising:
acquiring a recognition result of a target face image collected at the target storage location in response to the target storage location receiving a weight change; and comparing the recognition result with a person identifier indicated by the picking task to obtain a person-related result, wherein the sending, if the comparison result is that the material information and the target material information are consistent, an open instruction to a stock-out turnstile at the exit location comprises:
sending the open instruction to the stock-out turnstile at the exit location if the comparison result is that the material information and the target material information are consistent and the person-related result is “consistent.”

8 . The method according to claim 6 , further comprising:
acquiring the recognition result of the target face image collected at the target storage location in response to the target storage location receiving the weight change; comparing the recognition result with a recognition result of a to-be-processed face image to obtain a person-related result; and acquiring a face image photographed by a face camera at the exit location for the target person, and using the face image as the to-be-processed face image, wherein the sending, if the comparison result is that the material information and the target material information are consistent, an open instruction to a stock-out turnstile at the exit location comprises:
sending the open instruction to the stock-out turnstile at the exit location if the comparison result is that the material information and the target material information are consistent and the person-related result is “consistent.”

9 . (canceled)

10 . The method according to claim 1 , wherein, when a weight of a material in the target warehouse is outside the preset weight range, the material is provided with a radio frequency identification (RFID) tag indicating material information, and
using the material information of the material held by the target person as the target material information comprises:
determining, when the weight of the target material is outside the preset weight range, material information corresponding to an RFID tag of the material held by the target person by using an RFID antenna at the exit location, and using the material information as the target material information, wherein the preset weight range respectively takes the first weight value and the second weight value as the weight lower limit value and the weight upper limit value.

11 . The method according to claim 1 , wherein, after the comparing the material information of the to-be-picked material in the picking task with the target material information, the method further comprises:
sending, if the comparison result is that the material information and the target material information are inconsistent, alarm information to an alarm device to cause the alarm device to give an alarm, wherein the alarm device is an acousto-optic alarm device, or the electronic tag corresponding to the target storage location.

12 . The method according to claim 1 , wherein, after the comparing the material information of the to-be-picked material in the picking task with the target material information, the method further comprises:
sending, if the comparison result is that the material information and the target material information are inconsistent, a picking anomaly message to a terminal held by the target person, to cause the terminal to display the picking anomaly message, wherein the picking anomaly message indicates taking more materials, taking fewer materials or taking a material by mistake; and sending op
