Access cabinet device based on MSP430F149 single-chip microcomputer fingerprint recognition

Abstract

The invention discloses an access cabinet device based on MSP430F149 (Mixed Signal Processor) single-chip microcomputer fingerprint recognition, relating to an MSP430F149 single-chip microcomputer technology, wherein the access cabinet device based on the MSP430F149 single-chip microcomputer fingerprint recognition is improved on the aspects of safety, convenience and maintenance easiness. The access cabinet device comprises main equipment, access cabinets and a repeater. In a system, a plurality of access cabinets constitute an access cabinet array, each access cabinet communicates with the main equipment through an Rs485 bus, and the system is of a bus type topological structure. The scale of the access cabinet array can be expanded freely, and at least 32 access cabinets can be driven under the condition of not increasing the buses and the repeaters.

Description

Technical field: [0001] The invention relates to an MSP430F149 single-chip microcomputer technology, in particular to an access cabinet system device based on the fingerprint identification of the MSP430F149 single-chip microcomputer. Background technique: [0002] The current access cabinet system generally has two types: mechanical and electronic. The mechanical access cabinet system adopts the traditional mechanical lock structure. By providing the user with a key, the user can use the key to realize the opening and closing of the access cabinet. This system has disadvantages such as low security and inconvenient maintenance. If the key is lost, the user's items can be easily taken away by others, and the locker maintainer may need to change the lock, which is very troublesome. Due to these disadvantages, mechanical access cabinets are gradually being replaced by electronic access cabinets. Electronic access cabinet...When people need to store items, control the drive ...

AI Technical Summary

Problems solved by technology

This way of working makes up for the defects of the mechanical access cabinet system to a certain extent, but because it is based on the way of providing password paper, it still has disadvantages such as low security, difficult maintenance and high maintenance costs.

The main problems are: if the password paper is lost, the stored personal items can be easily taken away by others; if the password paper is wrinkled, the barcode may not be read correctly; Parts, resulting in complex design, high cost, large volume, and prone to failures such as paper jams and incomplete printing; due to the one-time use of password paper and the frequency of printing, a considerable amount of paper and ink resources will be consumed every day; regular Routine maintenance such as adding paper and ink is expensive
