Description
Technical Field
The invention relates to the technical field of intelligent warehousing systems, in particular to an intelligent warehousing control system based on infrared light screen supervision.
Background
Under the application scenes of intelligent communities, intelligent logistics, intelligent factories, intelligent security and the like, the storage and the handover of goods are often involved, so that an intelligent warehousing management system is necessary to be introduced. The whole-process tracking and supervision of goods are an important component of intelligent warehousing management, and can be widely applied to various scenes, such as warehousing of high-value goods, dangerous chemicals and fresh-keeping articles.
In the existing intelligent warehousing management system, when an article is warehoused, an ID number of the article is registered to the management system through code scanning, information such as a name, weight and the like associated with the ID number is registered, and then a cargo space number where the article is placed on a warehousing shelf is recorded. And when the goods are taken out of the warehouse, the goods position number is searched through the ID number, then the goods are found on the corresponding goods position number, and the goods are taken away after the goods are registered and taken out of the warehouse.
However, the prior art does not monitor the goods during the placement of the goods on the shelf, for example, it cannot monitor whether there is a situation that the goods are placed on the shelf or taken from the shelf without being registered, whether the goods placed on the shelf and the number of the goods are consistent with the registered goods, and whether the goods placed on the shelf are mixed due to the appearance of the cross position (cross to the adjacent goods position) caused by external force.
For a traditional storage mode, the articles on the shelf are required to be searched by workers when being staggered, or the articles on the shelf are regularly and intensively checked to correct the conditions of unregistered or error registration and the like; however, this is based on manual work, and it takes much time and labor cost. In addition, modern intelligent warehouses increasingly use robots for warehouse-in and warehouse-out, and the robots are far less intelligent and flexible than manual robots and lack self-correcting capability. For example, chinese patent CN104268738B discloses an intelligent material storage and access method, which includes the following steps: material coding; the feeding device sends a material tray filled with materials to a material placing platform at a material feeding window of the intelligent warehouse; a manipulator of the intelligent warehouse automatically grabs the materials and stores the materials into a bin of the intelligent warehouse at an address specified by the material management software system; when discharging, the manipulator takes out the material tray in the bin address appointed by the storage system and conveys the material tray to the material conveying belt of the intelligent warehouse, and the material conveying belt conveys the material tray to the discharge port of the intelligent warehouse to complete the discharging of the intelligent warehouse. The intelligent warehouse shipment system that this patent was disclosed, in case because reasons such as mechanical failure, collision, earthquake lead to article cluster position, this system will make mistakes, can't find the article that need the shipment or take wrong goods, and the manipulator of even shipment can't grab steady material dish, causes the condition of goods breakage damage that falls.
