Description

Technical Field

[0001] This utility model relates to the field of emergency lighting controller technology, and in particular to an emergency lighting controller based on a DI input circuit. Background Technology

[0002] Emergency lighting controllers are an essential component of centralized fire emergency lighting and evacuation guidance systems. They control and display the operational status of centralized fire emergency lighting fixtures, centralized power supplies, distribution boxes, and related accessories. In the event of a fire or emergency, they activate the emergency lighting fixtures and indicate directions, guiding personnel to safe areas and minimizing casualties.

[0003] In centralized control fire emergency lighting and evacuation guidance systems, there are two main types of linkage between the emergency lighting controller and the automatic fire alarm system (FAS): fire alarm point protocol linkage and DI input signal linkage. Fire alarm point protocol linkage is mainly used in large smart buildings that require precise fire location positioning, centralized monitoring, and unified platform management, as well as scenarios requiring refined linkage control by area. DI input signal linkage is mainly used in scenarios such as multi-brand system integration, renovation or expansion of old systems that do not support standard communication protocols and cannot exchange data, and small projects with simple functional requirements. First, in some renovation projects, the automatic fire alarm system (FAS) does not support standard protocol output and cannot obtain fire alarm location information through the protocol. At the same time, the project requires the emergency lighting controller to achieve precise zone control, and the traditional single-loop DI input linkage can no longer achieve the zone control function. Second, in some new projects, the project requires simple debugging and easy maintenance. The traditional fire alarm point protocol linkage has a long testing cycle, is susceptible to network communication interference, and is difficult to maintain, thus failing to meet the needs of such field applications.

[0004] Utility model patent CN203661381U discloses an emergency lighting controller, including a main board, a circuit expansion board, a fire alarm communication board, and a fire power supply. The fire alarm communication board is connected to the first interface of the main board for external communication. The circuit expansion board is connected to the second interface of the main board and includes several sub-circuit circuits, each connected to a fire emergency light fixture. The fire power supply is equipped with AC and DC terminals and is connected to and supplies power to the main board, the fire alarm communication board, and the circuit expansion board respectively. The fire alarm communication board receives a fire alarm signal and transmits it to the main board. The main board generates evacuation routes based on the fire alarm signal, combined with information such as building structure, evacuation path width, and personnel load. The programming method is simple and flexible. Although this patent also discloses a circuit expansion board that can expand circuits, it cannot expand the DI input circuit.

[0005] Therefore, providing a controller that extends the DI input loop is an urgent problem to be solved. Utility Model Content
