It should be noted that, in step S41, in order to obtain the number of material to be picked, the value obtained after the material picking person leaves is subtracted from the value obtained when the rack to be picked is activated to enter the work, and the subtracted value is multiplied by a value preset in the singular number of the material to be picked, so that the number of the material to be picked can be obtained;
the material statistics method is only one method, and in practical application, the number of materials can be counted by using radio frequency, image vision, and other methods, and the technology for realizing statistics is selected according to the characteristics of the materials, such as weight, size, or management requirements, as long as the materials can be counted, which is not described herein in detail.
In an embodiment of the present invention, obtaining a value t0 when the to-be-claimed rack is activated, obtaining a value t1 when the to-be-claimed person leaves, presetting a single value of the to-be-claimed material as g, and the number of claimed materials as n, and obtaining the number of claimed materials as n = (t 0-t 1)/g includes:
s42, comparing the number n of the materials to be received with the number wn of the materials to be received, if n = wn, displaying the materials to be received by the billboard to finish receiving, and if n ≠ wn, prompting that the number of the materials to be received is abnormal by the billboard by using voice and a screen.
It should be noted that, in step S42, the number of the material to be received is compared with the number of the material to be received, and if the number of the material to be received is equal to the number of the material to be received, the material to be received is displayed on the billboard to be received, and if the number of the material to be received is not equal to the number of the material to be received, the number of the material to be received is prompted to be abnormal by using the speaker and the screen through the billboard, so that the material receiving person can correct the material receiving error in time.
In an embodiment of the present invention, if n ≠ wn, the prompting of the abnormal quantity of the material to be claimed by the kanban using voice and screen questions includes:
s43, under the condition that the quantity of the materials to be received is abnormal, the material receiving personnel leave the warehouse, and the central control system can record the current complete material receiving video and the wrong material receiving record.
It should be noted that, in step S43, in order to facilitate tracing back of a wrong material received, after the number of the materials to be received is prompted to be abnormal, the material receiving person still leaves the warehouse, and then the current material receiving video and the wrong material receiving record are recorded completely, and the material receiving record in the abnormal situation is marked, so as to prompt an operator to check and trace back.
In an embodiment of the present invention, after the monitoring system in the warehouse detects the material getting person, the vision system determines the position of the material getting person and the position of the material to be got according to the video acquired by the monitoring system, and uploads the determined positions to the central control system, and before the central control system plans the path and sends the path to the signboard carried by the material getting person, the method further includes the following steps:
