Storage cabinet based on FPGA control and object storage and fetching method

Abstract

The invention discloses a storage cabinet based on FPGA control and an object storage and fetching method. The storage cabinet comprises: an FPGA mainboard, an external keyboard, a display screen and a plurality of storage cabinet main bodies; each storage cabinet main body comprises a relay, an electromagnetic lock, a door closing motion capture trigger and an ultrasonic detection device. The output ends of the door closing motion capture triggers are connected with the input end of the FPGA mainboard; the output end of the FPGA mainboard is connected with the relays, the relays are connected in the loops where the corresponding electromagnetic locks are located; the FPGA mainboard is in bidirectional communication connection with the ultrasonic detection device; the output end of the external keyboard is connected with the input end of the FPGA mainboard, and the output end of the FPGA mainboard is connected with the input end of the display screen; the FPGA mainboard is used for generating a cabinet opening password, controlling to open a cabinet door, determining whether the cabinet is an empty cabinet or not and verifying whether the password is correct or not. According to the invention, a user does not need to carry any unlocking article after storing the article.

Description

technical field [0001] The invention relates to the field of public lockers, in particular to a locker based on FPGA control and a method for depositing and fetching objects. Background technique [0002] With the development of the social public service industry, shopping malls, schools, libraries and other places need a lot of storage to facilitate people's temporary placement of personal items. Existing lockers include mechanical lock lockers and barcode lockers. Both mechanical lock lockers and barcode lockers require users to carry corresponding unlocking items. For example, mechanical lock lockers need to carry keys, while barcode lockers need to carry barcodes. Although it provides users with the convenience of storing items, but at the same time However, it increases the burden on the user to carry the unlocked item, and cannot provide the user with the convenience of not having to carry the item. Contents of the invention [0003] The object of the present inven...
