Folding 3, system software design

Intelligent combination lock with 51 series MCU assembly language software for intelligent monitor and electronic locks programming respectively.Intelligent monitor software including keyboard scanning and LCD display program, buzzer driver, clock modification and read program, data communication and pretreatment and intelligent analysis program, line monitoring program module, etc.Electronic locks software including keyboard scanning and decoding procedures, LCD display program, communication program, the electromagnetic actuator drive, testing procedures, sensor interface module, etc.In the process of software design using modular design method to facilitate reading, debugging, and improvement program.

Intelligent combination lock make full use of the 51 single-chip microcomputer software and hardware system resources, introduced the intelligent analysis function, improve the reliability and security of the system.By a type safe installation, was welcomed by users.In addition, the intelligent combination lock changed slightly in hardware and software aspects, can constitute a intelligent distributed monitoring network, to achieve a range of centralized monitoring and management, in finance, insurance, military area and other security areas has broad application prospects.


The development process

Is the so-called smart locks, electronic technology, integrated circuit design, a large number of electronic components, combined with a variety of innovative recognition technology (including the computer network technology, the built-in software card, network alarm, mechanical design of the lock body) and other integrated products.

Electronic combination lock research began in the 1930 s, has long been used in some special places.Electronic lock key (password), can be used with mechanical lock, and could be avoided by keys are generic security hidden danger.Electronic lock just remember a set password, without having to wear the metal key people carry metal key from the worry, and so became more and more people admire.After the 1980 s, with the emergence of application-specific integrated circuit for electronic lock, electronic lock smaller, improve reliability, high cost, is suitable for use in requiring higher security, and have power to provide energy, the use is limited in a certain range, difficult to popularize, so the study of it has been no significant progress.

In the 90 s, the United States, Italy, Germany, Japan, Canada, South Korea, and China's Taiwan, Hong Kong and other places of the development of microelectronic technology and communication technology provide the technical support for the combination lock, so as to promote the combination lock to the practical application stage.In the 21st century, in the western countries, electronic combination lock technology is relatively advanced, complete variety, electronic combination lock has been widely used in the intelligent entrance guard system, make them safer and more reliable to achieve the management of the gate.

Beginning in the early 90 s in China for a preliminary exploration of combination lock.So far, with the development of electronic technology and information technology, electronic combination lock technology has developed very mature.From the technical level and the degree of market recognition in the early 20th century, the most widely used is the keyboard type electronic combination lock, the product is mainly used in the safe, safes and vaults, and part of applied to safekeeping and vans.In other technology and remote control type electronic combination lock and card combination lock, etc.

Because of this "long since born, carry" "keys" advantage, so this kind of lock quickly through the initial stage performance is not so stable, the price is expensive, is becoming more and more practical, more and more "characteristics", broadly welcomed by the people.Today, biometric technology is developing rapidly, in addition to price and volume size factors of popularization is limited, the prospect of biological characteristics of electronic anti-theft lock in the financial sector is widely favored.As Numbers, characters, graphics, images, the biological characteristics and time can be the key factors of electronic information, combine the information electronic anti-theft lock can acquire a high degree of confidentiality.Use a combination of information will also be able to make electronic anti-theft lock for the possibility of infinite expansion, make the product diversification.

At the beginning of the 21st century.The contact card of mature technology and low price, are widely used;Non-contact card using hidden, convenient, thus greatly.Store large amount of information is the advantage of the card, it not only as the key, still can load a number of personal information, especially suitable for the financial sector pay attention to the industry characteristics of "of", and one card use (such as the introduction, the lock, storage, payment, etc.) from the cardholder's convenience.Use this type of electronic anti-theft lock, need careful custody CARDS (key), especially lost must cancel the authorization of the card as soon as possible.

At the beginning of the 21st century, in the western developed countries, combination lock is relatively advanced technology, complete variety, electronic combination lock has been widely used in the intelligent entrance guard system, through a variety of more safe and reliable technology to realize the management of the gate.Combination lock in our country overall level is still in the 70 s, international electronic combination lock cost is high, the market still is given priority to with electronic lock button, button type key and card type electronic lock has introduced the international advanced level.But developed by domestic electronic lock, its market structure has not yet formed, is not widely used.Many domestic enterprises also introduced the world advanced technology, development prospect is very considerable.

Intelligent lock to replace mechanical lock is an inevitable trend, there is reason to believe that smart locks will with its unique technical advantages, led the development of China's lock industry better, let more people more comfortable in more occasions to use, will make our future more secure.
