Abstract

The utility model provides an intelligent automatic storing device. The utility model is characterized in that the device comprises a bar code scanner; the terminal of the bar code scanner is connected with a serial port of a chip of a single-chip microcomputer through an RS232 interface; the chip of the single-chip microcomputer is provided with a port for writing in programs; the device also comprises a storing cabinet; the storing cabinet is provided with a control circuit; a drive circuit is arranged between the single-chip microcomputer and the storing cabinet; the device also comprises a matched bar code card. The utility model reads the bar code of a user by the bar code scanner. If the bar code is new, the storing cabinet opens an empty cabinet door through judgment; if the card is old, the cabinet door corresponding to the number is opened, and the record of the card number is deleted. Thus, each cabinet door can be used by any user having the bar code. The utility model is suitable for storing articles in public places, such as libraries, railway stations, supermarkets, bathrooms, etc. The utility model has the advantages of good safety, convenience to service objects, convenient management, etc.

Description

Intellectual automatic memory storage

Technical field

The utility model relates to a kind of automatic memory storage that is used for public place article storage such as library, railway station, supermarket, publilc baths, and what relate to specifically is a kind of automatic memory storage by bar code control.

Background technology

It is to adopt wooden form cabinet that the mode of present public place stores has a kind of, every lattice can be deposited a people's article, but every lattice are not all established cabinet door and no one management, depositing in and getting is personal behavior fully, and without any constraint, whether the safety of depositing article depends on very big potential safety hazard is arranged user's total quality and moral culture; Also having a kind of is the cabinet of band cabinet door and lock, because its lock adopts old-fashioned mechanical lock, and the use object of cabinet constantly changes, and this just makes key be difficult to management, is difficult to obtain real application in public places.

Summary of the invention

The purpose of this utility model is in order to solve the weak point of above-mentioned present situation, to provide a kind of security good, the intelligent automatic memory storage of being convenient to manage.

For achieving the goal, the utility model provides following technical solution: a kind of intellectual automatic memory storage is characterized in that: include a bar code scanner in this device, the terminal of bar code scanner connects the singlechip chip serial port through the RS232 interface; Singlechip chip has program to write inlet; Also include the cabinet that opens and closes by single-chip microcomputer generation signal controlling in this device, be provided with driving circuit between single-chip microcomputer and the cabinet; Control circuit is housed on the cabinet; This device also comprises the barcode card that is complementary with native system.

Feature of the present utility model is that also the SCM peripheral circuit is provided with key circuit that links to each other with keyboard and the display circuit that links to each other with display.

Feature of the present utility model also is, also is provided with the interchange power cut detection circuit on the SCM peripheral circuit.

The utility model utilizes the intelligent management function of single-chip microcomputer, by bar code scanner user's bar code is read, by judging, if new bar code just makes single-chip microcomputer open empty cabinet door of cabinet; When old card, open the cabinet door of this card number correspondence, and delete the record of this card number.Each cabinet door can offer any one user who has bar code use in turn like this.Because each bar code is storage in use only, has so both made the user who faces many again, also only need very little memory data output, so just do not need to expand the storer of single-chip microcomputer, greatly reduce cost.Be applicable to the storage of public place article such as library, railway station, supermarket, publilc baths.Have security good, make things convenient for the service object, be convenient to advantages such as management.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail:

Among Fig. 1, Fig. 2, the terminal of bar code scanner 1 connects single-chip microcomputer 3 serial ports through the RS232 interface, and single-chip microcomputer 3 is AT89C51.Single-chip microcomputer 3 has program to write inlet; Single-chip microcomputer 3 peripheral circuits are provided with key circuit 5 that links to each other with keyboard and the display circuit 6 that links to each other with display; Be provided with driving circuit 7 between single-chip microcomputer 3 and the cabinet 8; On the cabinet 8 control circuit is housed; Control circuit on the cabinet 8 is the electronic induction switch that relay switch or motor action switch constitute.The control signal that single-chip microcomputer 3 sends is amplified the control circuit that rear drive is made of inductive switch through driving circuit 7, to reach opening of control store cabinet.Control circuit and driving circuit all adopt custom circuit.The effect that exchanges power cut detection circuit 4 is: if civil power does not stop, then it makes pin become low level " 0 ".Then it makes pin become high level " 1 " if having a power failure, and after single-chip microcomputer 3 detects this signal, makes corresponding action by programmed control single-chip microcomputer 3, guarantees the normal operation of total system.

Among Fig. 3, in master routine, single-chip microcomputer at first carries out initialization to various initial values, then just constantly to GF ₀Zone bit is inquired about, if GF ₀=1, then make IDL=1, single-chip microcomputer enters power-down state, so that data are in time protected, guarantees the normal use of system.

Among Fig. 4, this program is T ₀When counter overflows, produce just that string is disconnected to enter this program from master routine, so that periodically to P _1.0Port is inquired about, and at first recovers T after entering program ₀Initial value is inquired about by the time of setting to guarantee the monolithic function.Single-chip microcomputer is inquired about P then _1.0Port if power-down conditions takes place in 1 explanation, is put GF ₀=1, if power-down conditions does not appear in 0 explanation, or power-down conditions is removed then clear GF ₀Be 0.All withdraw from T after handling two kinds of situations ₀Program is returned master routine.

Among Fig. 5, the serial ports interruption subroutine is the read-in programme of bar code, single-chip microcomputer whenever reads in a bar code, just by searching to existing number to judge whether existing this program, if have then open corresponding cabinet door, remove to carve the record number in storer then, if this card number then find out empty this card number of storage area stores and open corresponding cabinet door not all returns master routine after handling above two kinds of situations.

Among Fig. 6, in this program, at first carry out key assignments and judge, if for " * " keyboard then be defined as inputing password.Correct as password, then send corresponding signal prompting please import to open cabinet door number, open corresponding cabinet door just single-chip microcomputer is controlled, and remove the card number record, return master routine.Be not " * " keyboard then jump to the card number program of reading if begin input, return master routine then.
