The article proposes a technology for controlling access through a Web application. In the first part, the implementation of the electromechanical part of the ACS, the key feature of which is the preservation of the last state when the power is turned off and the presence of an anti-panic mode. This feature is obtained by installing a geared motor on the lock cylinder. This solution allows you to abandon the need for certification of the lock, use both electronic control, for example, by means of a telephone or proximity cards, and classical control using a regular standard key, as well as finding the lock in any state for an arbitrarily long time, regardless of the presence of power. In the second part, the implementation of network interaction between the user and the directly controlled object is proposed.

This article describes an automated electronic load control system. The peculiarity of this system is the unifi- cation of instrumental means intended for scientific research with the technologies of industrial automation.

This article discusses the design of a physical access control system for an enterprise with various methods of authentication and user identification. A review of existing solutions in the design of physical access control systems was conducted. In the course of the work, a system design was proposed, and its components were described in detail.
