Abstract
The invention discloses an electronic coded lock which comprises a singlechip microcomputer control module, a display, a keyboard used for inputting a password and a function control signal, a storage device used for storing a primary set code, an unlocking circuit and a power supply used for supplying power to the lock, wherein the singlechip microcomputer control module comprises a reset circuit and a crystal oscillation circuit, and is used for receiving the signal input by the keyboard, comparing the signal with the primary set code in the storage device and controlling the unlocking circuit to act according to a comparison result; the display is connected with the singlechip microcomputer control module and used for displaying the password and characters representing correct or incorrect password input; the storage device is connected with the singlechip microcomputer control module. The electronic coded lock is good in safety and almost impossibly randomly unlocked; when the number of password input error times exceeds the limited number of times, a system can lock the keyboard for a period of time and give an alarm; very few moving parts are required and almost cannot be worn, so that the electronic coded lock is very long in service life.
Description
Technical field
The present invention relates to electronics field, particularly a kind of electronic password lock.
Background technology
In recent years, social economy is fast-developing, and people more and more focus on the problem of safe antitheft.How to make theftproof lock safe and reliable, easy to use, be the theme of lockmaking person's development for a long time always.Current electronic science and technology develops rapidly, and the function of electronic password lock is more and more comprehensive, has the multi-functional Puzzle electronic locks such as antitheft, warning and instead of mechanical code lock.
Summary of the invention
In view of this, the object of this invention is to provide a kind of electronic password lock, security is good, may unblank at random hardly, Password Input mistake exceedes the number of times of restriction, and system can lock the keypad a period of time reporting to the police, movable members is little, and have wearing and tearing hardly, the life-span is very long.
The object of the invention is to be achieved through the following technical solutions:.
Electronic password lock of the present invention, comprise single chip control module, display, for Password Input and function control signal input keyboard, for storing the original reservoir, unlock circuit and the power supply for powering to this lock that arrange password, described single chip control module comprises reset circuit and crystal oscillating circuit; Described single chip control module receives the signal of input through keyboard and contrasts with the original password that arranges in reservoir, and then control unlock circuit action according to comparing result, described display is connected with single chip control module, for showing password and representing the correct or wrong character of Password Input, described reservoir is connected with single chip control module.
Further, described coded lock also comprises the warning device be connected with single chip control module, and the instruction that described warning device reception single chip control module sends also makes corresponding response;
Further, described warning device is piezoelectric ceramics sound-producing device;
Further, described keyboard is 4 × 4 matrix keyboards;
Further, described coded lock also comprises the pilot lamp that or mistake correct to Password Input responds.
Further, arrange telephone number by keyboard to this single chip control module, the signal that described single chip control module is received sends note by gsm module to user or makes a phone call.
The invention has the beneficial effects as follows:
This electronic password lock security is good, may unblank at random hardly, and Password Input mistake exceedes the number of times of restriction, and system can lock the keypad a period of time reporting to the police, and movable members is little, and have wearing and tearing hardly, the life-span is very long.
Other advantages of the present invention, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or can be instructed from the practice of the present invention.Target of the present invention and other advantages can be realized by instructions below and claims and be obtained.
Accompanying drawing explanation
In order to make the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail, wherein:
Fig. 1 is structural representation of the present invention.
Embodiment
Hereinafter with reference to accompanying drawing, the preferred embodiments of the present invention are described in detail.Should be appreciated that preferred embodiment only in order to the present invention is described, instead of in order to limit the scope of the invention.
Electronic password lock of the present invention, comprise single chip control module, display, for Password Input and function control signal input keyboard, for storing the original reservoir, unlock circuit and the power supply for powering to this lock that arrange password, single chip control module comprises reset circuit and crystal oscillating circuit; Single chip control module receives the signal of input through keyboard and contrasts with the original password that arranges in reservoir, and then control unlock circuit action according to comparing result, display is connected with single chip control module, for showing password and representing the correct or wrong character of Password Input, reservoir is connected with single chip control module; Single-chip microcomputer in the present embodiment is AT89C51, and display is LED1602, and reservoir is AT24C04, and other types electronic devices and components certainly also can be adopted to replace.
Further improvement, coded lock also comprises the warning device be connected with single chip control module, the instruction that warning device reception single chip control module sends also makes corresponding response, and this warning device is piezoelectric ceramics sound-producing device, also can adopt the sound-producing devices such as hummer.
Further improvement, the present embodiment keyboard is 4 × 4 matrix keyboards, also can adopt the keyboard of other types.
Further improvement, coded lock also comprises the pilot lamp that or mistake correct to Password Input responds.
Further improvement, arranges telephone number by keyboard to this single chip control module, and the signal that single chip control module is received sends note by gsm module to user or makes a phone call.
If user needs to unlock, first must press the solution locking key on lower keyboard, then 6 passwords in input number keyboard dish character 0-9, acknowledgement key is pressed after password is totally lost, if the password of input accurately lock can be opened automatically, if display lamp can not be bright when input password is inaccurate, user must re-enter password, when third time Password Input error system meeting automatic alarm; If user wants to change original password, keyboard inputs old password correct after just can new password be set, can show on a display screen after new password input and remember new password and pre-anti-operation failure with reminding user.
This electronic password lock security is good, may unblank at random hardly, and Password Input mistake exceedes the number of times of restriction, and system can lock the keypad a period of time reporting to the police, and movable members is little, and have wearing and tearing hardly, the life-span is very long.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of the technical program, it all should be encompassed in the middle of right of the present invention.
