Description
Technical field
The utility model relates to a kind of lockset, is specifically related to a kind of electronic password lock.
Background technology
Along with the raising of development of science and technology and social life level, the electronic password lock with safe antitheft function is just slowly come into our life.Traditional mechanical lock is owing to its simple structure, and poor safety performance is is very easily worn and torn; Must rely on key and just can open lockset, this is very inconvenient; Go out leave behind key or key and lose in, opening the door has just become a difficult problem.
Summary of the invention
The purpose of this utility model is, a kind of simple to operate, electronic password lock that function is practical is provided, and can realize the unlatching of door lock, the life that is convenient for people to by button or infrared remote control.
In order to realize above-mentioned task, the utility model is solved by the following technical solutions:
A kind of electronic password lock comprises the keyboard, hummer and the display that are arranged on outer side of door, and this electronic password lock also comprises electromagnet and the single-chip microcomputer that is arranged on an inboard, and electromagnet drives chip by one and is connected with single-chip microcomputer; Also be connected with a storage chip and an infrared receiving terminal on single-chip microcomputer, doorframe is provided with an iron core corresponding with electromagnet, and described keyboard, hummer and display are connected with described single-chip microcomputer respectively.
Other technologies characteristics of the present utility model:
Described single-chip microcomputer adopts AT89C51 type single-chip microcomputer.
Described electromagnet adopts TSO-0837L type electromagnet.
Described driving chip adopts ULN2003 to drive chip.
Described display adopts the LCD1602 escope.
Described storage chip adopts AT24C02 chip-stored chip.
Described infrared receiving terminal HS0038 type infrared receiving terminal.
The utility model provides a kind of safe and reliable electronic door lock device, this device can be inputed password or adopt the mode of infrared remote control to open door lock by button, and do not need key to unblank, and avoided the mechanical wear of traditional mechanical lock, it is convenient to have brought for people's life.
Description of drawings
Fig. 1 is annexation synoptic diagram of the present utility model;
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
Defer to technique scheme, as shown in Figure 1, present embodiment provides a kind of electronic password lock, comprises the keyboard, hummer and the display that are arranged on outer side of door, this electronic password lock also comprises electromagnet and the single-chip microcomputer that is arranged on an inboard, and electromagnet is connected with single-chip microcomputer by a relay; Also be connected with a storage chip and an infrared receiving terminal on single-chip microcomputer, doorframe is provided with an iron core corresponding with electromagnet, and described keyboard, hummer and display are connected with described single-chip microcomputer respectively.
In the present embodiment, single-chip microcomputer adopts AT89C51 type single-chip microcomputer, and AT89C51 is a kind of low-voltage with 4K byte FLASH storer, high-performance CMOS 8-bit microprocessor, and the erasable read-only memory of this single-chip microcomputer can repetitive erasing 1000 times.This device adopts ATMEL high density nonvolatile memory manufacturing technology to make, and is compatible mutually with MCS-51 instruction set and the output pin of industrial standard, and single-chip microcomputer is used for judging whether the password of the password of keyboard input and setting is identical, and control output.
Described electromagnet adopts TSO-0837L type electromagnet, and this electromagnet is a kind of DC electromagnet, and spring device is arranged in the electromagnet, makes that the iron core in the electromagnet can be got back to original position after outage.
Described driving chip adopts ULN2003 to drive chip, this chip is a kind of high withstand voltage, big electric current Darlington array, characteristics such as have current gain height, operating voltage height, temperature range is wide, carrying load ability is strong, be adapted to each generic request at a high speed, powerful drive unit, this chip is used for drive magnetic in this device.
Described display adopts the LCD1602 escope.It is a kind of dot matrix type Liquid Crystal Module that is used for showing letter, numeral, symbol etc. specially.It is made up of dot character positions such as several 5X7 or 5X11, and each dot character position can show a character, and the interval of a some distance is arranged between every, also has between every row at interval, has played the effect of character pitch and line space.
Described storage chip adopts AT24C02 chip-stored chip, and the effect of this storage chip is the encrypted message that storage is set.
Described infrared receiving terminal HS0038 type infrared receiving terminal, this reception head and Infrared remote controller are used, its effect is to give unlocking signal of single-chip microcomputer by infrared remote control, make the people in the room picks out outdoors people by language communication after, do not need to go in front of the door and just can open the door by telepilot.
The course of work of this device is such: configure door-opening password information before using in storer, the normal condition lower electromagnet is in "on" position, and namely the energising iron core in the electromagnet tightly adsorbs the iron core on the doorframe, makes door be in the state of closing.When entering, by being arranged on the keyboard of outer side of door, the input password, single-chip microcomputer compares the password in this password and the storer, if two passwords are identical, just stops drive magnetic work by driving chip, iron core power down in the electromagnet at this moment loses magnetism, and door can be opened; If input password by mistake, then show the information of " password mistake " at display; If three times are inputed by mistake password, then hummer yowls and warns.Except opening the door by keyboard, can also realize opening the door by the telepilot that cooperates with infrared receiving terminal; For example the householder only need press telepilot in the effective range of receiving of infrared receiving terminal when going home, after infrared receiving terminal receives remote controller signal, namely this signal is passed to single-chip microcomputer, single-chip microcomputer can be realized the temporary transient outage of electromagnet by driving chip, thereby opens door.
The electronic devices and components that the utility model adopts are known product, and those skilled in the art are according to the i.e. concrete connected mode of electronic devices and components as can be known of the technical solution of the utility model.
