Because it has the logic operation and the logical processing function, therefore calls then umeral logic circuit. Numeral logic circuit classification (according to function minute):1st, combinatory logic electric circuitThe abbreviation combination circuit, it becomes by the most basic logical gate electric circuit combination. The character is tic is: Output value only and then input value related, namely output only by then input value decision. The electric circuit has not remembered the function, the output condition changes along with the input condition change, is similar to the resistance electric circuit, like the accumulator, the decoder, the encoder, the data selector and so on all belong to this kind.2nd, succession logic circuitThe abbreviation sequence circuit, it is adds on the feed back logic return route by the most basic logical gate electric circuit (to output the electric circuit which input) or the component combination becomes, lies in the sequence circuit with the combination circuit essence difference to have the memory function. The sequence circuit characteristic is: The output not only was decided by then input value, moreover also the and circuit past condition concerned. It is similar to containing the stored energy part the inductance or the electric capacity electric circuit, like electric circuit and so on trigger, latch, counter, shift register, reservoir all is the sequence circuit typical component.Digital circuit characteristic:1st, simultaneously has the arithmetic operation and the logic operation functionThe digital circuit is take the binary system logic algebra as mathematics foundation, the use binary numeral signal, both can carryon the arithmetic operation and to be able conveniently to carry on the logic operation (with, or, non-, judgment, comparison, processing and so on), therefore extremely suits to application and so on operation, comparison, memory, transmission, control, decision-making.2nd, realization simple, the system is reliableBy binary system underlie numeral logic circuit, simple reliable, the accuracy is high.3rd, integration rate high, the function realization is easyIntegration rate high, volume small, the power loss is low is one of digital circuit prominent merits. Electric circuit design, service, maintenance nimble convenient, along with the integrated circuit technology high speed development, the numeral logic circuit integration rate is more and more high, integrated circuit block function along with small scale integration electric circuit (SSI),center scale integrated circuit (MSI), large scale integrated circuit(LSI), ultra large scale integrated circuit (VLSI)the development also from the part level, the component level, the part level, the board card level risesto the system level. The electric circuit design composition only must use some standards theintegrated circuit block unit connection to become. Also may use the programmable foreword logic array electric circuit regarding the non- standard special electric circuit, through programming method realization free logic function.Digital circuit application:Digital circuit and numeral electronic technology widespread application to science and technology each domain and so on television, radar, correspondence, electronic accounting machine, automatic control, astronautics.2.Digital code lock System Status and Development TrendRecent years, along with reform and open policy thorough development, electronic appliance's swift development. People's living standard had the very big enhancement. Each kind of upscale electrical appliances product and the valuables have for many families. However some unlawful elements are also more and more. This sees majority of person security consciousness also insufficient. Creates steals the phenomenon to be common. Therefore, more and more resident families worried to the property security problem. the alarm apparatus had been solving many problems by now for the people. But in the market alarm apparatus majority of use in some big company fiscal institution. The price is soaring, generally the people accept with difficulty. If redesigns and produces one kind moderately-priced, the performance keen reliable burglar alarm, will certainly plays a more effective role in security and the guarantee property security aspect. As the electronic code lock is a password to enter the control circuits, or chips, so as to control mechanical switches closed, the completion of the lock, closed the task of electronic products. It's a lot of species, there is a simple circuit products as well as chip-based products more cost-effective. Now a wider application of electronic locks is at the core chip.The electronic technology has obtained the rapid development, under its impetus, the electronic products nearly seeped society's each domain now, powerfully impelled in the social product development and the social becoming an information based society degree enhancement, simultaneously also is makes the modern electronic products performance further to enhance, the product renewal rhythm more and more is also quick. First the EDA technology after enters for the 21st century, obtained the very big development, its basic characteristic uses the higher order language description, has System the simulation and the synthesizing capacity. The VHDL hardware description language is designs the source document to be possible to use is similar with the C language written form, and uses the structural design method. Along with the people living standard enhancement, the password lock took the family security bodyguard's function is day by day important, it compared to has some unique superiority with the ordinary mechanical phase-lock, for example: Secret, the security performance is good, may not use the key, so long as remembers the password then unlock.The EDA technique develops trend: The EDA technique is after get into 21 centuries, because of more large-scale FPGA and continuously release of the cave m spare part are really imitate with design the both side support a standard hardware description, the function strong EDA software of the language continuously renews, increment, make the electronics EDA's technique get a larger development. The electronics technique is all-directions to bring into EDA realm, the EDA make electronics the boundary of each academics of realm be getting more misty, more with each other in order to forgive, the outstanding performance is at following few aspects: Makeelectronics design the result can definitely express to make possible with confirmation by independent intelligent property right; Design standard unit according to the ASIC of EDA tool have already covered large-scale electronics system and the IP pit mold piece; The soft hardware IP pit gets further confirmation in industry realm, technique realm and the design applied realm of electronics profession; The SoC efficiently low cost design technical maturity. Along with the semi-conductor technique, integrated technique and the calculator technical fast fierce development, design method and design means of electronics system all took place very big variety. Can say electronics EDA's technique's is an electronics design is a revolution of the realm. The design method of traditional” fix function integration piece ten on-lines" just and gradually with draws history stage, but is become modern main current of design of the electronics system according to the design method of chip. Be Gao Deng3 college's understanding and climbing to hold this advanced technique concerning the professional student and the large electronics engineer be certainly to be necessarily going, this not only is the demand of efficiency of the exaltation design, more that time generation need for develop, only climbed to hold the EDA technique just includes the competition that the ability participates the industrial market of the world electronics, then can exist with development. Along with the progress of science and technique revolution of the realm and electronics industry field of the electronics design, also in the meantime to electricity course of teaching and research put forward more deeply higher request. Especially the EDA technique hasn't make widely available in the our country and control is this all new technique with universality, will to our country the electronics technical development have profound meaning.3.Electronic Lock System of Non-contact IC CardBased on the research of RS485 and TCP/IP Communication Protocol, the paper introduces an Electronic Lock System of Non-contact IC card and puts forwards the solution of the whole system.
