Embodiment
Now by reference to the accompanying drawings and specific embodiment, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present invention is only described in a schematic way, and therefore it only shows the formation relevant with the present invention.These embodiment are interpreted as only need not limiting the scope of the invention for the present invention is described.After having read content of the present invention, those skilled in the art can do various amendments to the present invention, and the variation of these equivalences and modification fall into the protection domain that the present invention limits equally.
The SCM Based electronic lock of one as shown in Figure 1, comprise single-chip microcomputer, Singlechip clock circuit, reset circuit, display device, keyboard, unlocking mechanism, single-chip microcomputer is connected with Singlechip clock circuit, display device, keyboard, unlocking mechanism respectively, the wherein implementation of Single-chip Controlling whole system, keyboard is for the input of electronic lock password, and display device is for the password of display keyboard input.As shown in Figure 2, unlocking mechanism comprises opening drive circuit and solenoid valve, described opening drive circuit is connected with single-chip microcomputer output port, and solenoid valve is connected with opening drive circuit, thereby single-chip microcomputer is controlled the switching of electronic lock by the switching of opening drive circuit control solenoid valve.For in order to understand better principle of the present invention and embodiment, the present embodiment can adopt cheap, develop general at89c51 single-chip microcomputer, if Fig. 3 is at89c51 legend, AT89C51 is the low-voltage of a kind of band 4K byte flicker programmable and erasable ROM (read-only memory) (FPEROM-Falsh Programmable and Erasable Read Only Memory), high-performance CMOS 8-bit microprocessor, is commonly called as single-chip microcomputer.The erasable read-only memory of single-chip microcomputer can be wiped 100 times repeatedly.This device adopts ATMEL high density nonvolatile memory manufacturing technology to manufacture, compatible mutually with MCS-51 instruction set and the output pin of industrial standard.Due to multi-functional 8 bit CPUs and flash memory are combined in one single chip, the AT89C51 of ATMEL is a kind of efficient microcontroller.
In order to make this circuit more succinct, the coded lock of this electronic lock adopts the Password Input of the phase of rubbing code easy to learn but that do not know for majority as circuit.Keyboard hardware device just is wanted one by input and the change that can realize password.
About being described below of Morse code:
This password that rubs is the one coding that used telegram transmission comparatively widely to use in 20th century.Telegram is to be invented in 1844 by the Morse of the U.S. the earliest, therefore be also called Morse code.Length interval time that it is pinned in the time inputting by an input key forms the input that decides you: very brief some signal ". ", read " ticking " (Di); Keep the long signal "-" of certain hour, read " clatter " (Da).Interval time: " ticking " 1t; " clatter " 3t; 1t between " ticktack "; 3t between letter; 5t between word.Morse code is used in digital circuit "-" and represents 1, and ". " represents 0, and to translate into binary number be 11111H as 0, and sexadecimal number is 1FH, and the concrete expression of password is as shown in the Morse code of Fig. 4 character-Morse code table of comparisons and Fig. 5 numeral and the scale-of-two table of comparisons.
For concrete understanding specific implementation of the present invention, if Fig. 6 is the physical circuit connection layout that this electronic lock system utilizes at89c51 single-chip microcomputer, native system circuit comprises at89c51, the clock-pulse circuit of crystal oscillator and two electric capacity compositions, the reset circuit of resistance and an electrochemical capacitor and a button composition, a password display that 8 segment numeral pipes form, a hummer, 5 LED, a NPN triode adds the driving circuit of a relay composition.Wherein the annexation of several important pins of at89c51 is: ALE pin is unsettled, and reset pin is received reset circuit, VCC and connect power supply, VSS ground connection, EA and connect power supply.
More than show and only described principal character of the present invention and inventive point.Those skilled in the art should understand, and the present invention is not restricted to the described embodiments.Do not departing under the prerequisite of point of the present invention and protection domain, the present invention also has various variations, and these changes and improvements all will fall in the scope of protection of present invention.The scope of protection of present invention is limited by appending claims and equivalent thereof.
