Smart home access control systems are a new type of modern security management system, integrating automatic identification technology and modern security management measures, involving many new technologies such as electronics, mechanics, computer technology, communication technology, and biotechnology. The smart home access control system is monitored by a computer or personnel in a central control room to control access. As an important part of the smart home security system, smart access control not only replaces the functions of traditional keys and manual entry and exit registration, but is also a diversified management tool. Smart home access control systems have obvious advantages.

　　Main components of the smart home access control system: CPU, reset circuit, Power supply Indicator, work indicator, oscillation circuit, buzzer circuit, door lock circuit, exit button, card reader module.

　　With its unique advantages, the smart home access control system serves the smart home security work. The smart home access control system has the following main characteristics.

　　A fully functional intelligent access control management system can implement computer management of entrances and exits in various places through simple scheduling procedures, thereby establishing an orderly management mechanism and model. For internal management, it can control the access areas and access of different personnel at any time. It also records the entry and exit of various personnel, providing rigorous means and detailed data for various management mechanisms;

　　For external management, it can politely refuse uninvited guests, effectively protecting the property within the controlled area from illegal infringement, and maintaining the normal work order within the area. Smart home access control systems typically use the STC11F52 single-chip microcomputer as the control core, with peripheral buzzer control circuits, door opening indicator circuits, Electric lock Control circuit and information upload circuit. Using Radio frequency card To complete the functions of swiping the card to enter and pressing the button to exit.

　　Smart home security work cannot be separated from the access control system. A well-designed access control system can provide effective protection for smart home security.
