Analysis of the functional characteristics of magnetic locks

A brief analysis is made on the overall design of the digital magnetic lock and its main functional features, and its characteristics, completed functions and simple operation of the system are summarized to promote the understanding of the single-chip microcomputer and its control system. An overview of the development of computer electronic technology and the presentation of system issues. At present, the single-chip microcomputer is developing towards high performance and multiple varieties. The development of the single-chip microcomputer is moving towards low power consumption, small size, large capacity, high performance, low price and internalization of peripheral circuits of CMOS. In recent years, due to some reasons, the advancement of CHMOS technology has greatly promoted the CMOSization of single-chip microcomputers. In addition to low power consumption, this chip also has controllable power consumption, so that the single-chip microcomputer can work in a state of precise power consumption management. Moreover, the single-chip microcomputer generally adopts a reduced instruction set structure and pipeline technology, which can greatly improve the operation speed, improve information processing functions, stop and timing control functions, and generally has serial expansion technology. With the development of low-cost 0TP and various types of on-chip program memory, coupled with the continuous entry of peripheral interfaces into the chip, especially the introduction of serial buses such as IIC and API, the pin design of the single-chip microcomputer can be reduced, and the system structure of the single-chip microcomputer can be simplified and standardized.

This leads us to use single-chip microcomputers to complete digital magnetic locks to complete anti-theft security. With the rapid development of electronic technology, computers have deeply penetrated into our lives. As for the 51 series, because Intel has transferred its core usage rights to many well-known international IC manufacturers in the form of patent exchange or sale, with the continuous development of computer technology, the use of single-chip microcomputers in the field of industrial measurement and control is becoming more and more widespread. Magnetic locks At the same time, with the continuous improvement of ultra-large-scale integrated circuit technology and integrated manufacturing technology, the hardware integration of single-chip microcomputers has also been continuously improved. Single-chip microcomputers that can meet various needs and have various special functions have emerged. This type of single-chip microcomputer has the advantages of high integration, excellent performance-price ratio, and sufficient supply. It has obtained extremely wide use value in the field of industrial measurement.

With the rapid development of social economy, security issues are becoming more and more serious, and prying incidents are emerging in an endless stream. In banks, hotels, shopping malls, aerospace and other departments, it is often necessary to monitor and alarm the environment to prevent theft. For banks, hotels, etc., anti-theft alarms are even more important. In the past, traditional mechanical locks had a single function, no intelligence, fixed position, and could not be easily transformed. Therefore, how to deal with this problem has become an urgent issue. The development of a digital magnetic lock that can be both simple and powerful is an element of the development of an information and intelligent era.
