AI Technical Summary
Existing interlocking door systems suffer from scattered equipment interfaces, complex wiring, inconvenient construction and maintenance, separation of display and control functions, and poor system compatibility, making it difficult to meet the high-efficiency, safe, and intelligent requirements of modern access control systems.
Design an interlocking door that includes an integrated display panel and wiring back panel, with access indicators, no-entry indicators, and emergency buttons. It also integrates component access terminals, a DC12V power supply port, a switch control line access terminal, and normally open and normally closed indicator lights. Multiple door panels are connected via a synchronization line to achieve status linkage, thereby improving safety and construction efficiency.
It enables status linkage between multiple doors, ensuring that only one door is open at any given time, thereby enhancing area isolation and security. The display panel integrates multiple functions, facilitating installation and maintenance, and improving safety and ease of operation.
