Fire-protection emergency sign lamp

Abstract

The invention discloses a fire-protection emergency sign lamp. The fire-protection emergency sign lamp comprises a direct current power supply module, a buck circuit module, an LED load module, a communication two-bus module, an MCU control module, an LED fault detection module and an emergency lighting controller; the direct current power supply module is connected with the LED load module through the buck circuit module; the output end of the LED load module is connected with the input end of the MCU control module and the input end of the LED fault detection module respectively; the output end of the LED fault detection module is connected with the MCU control module; the MCU control module is connected with the communication two-bus module; and the communication two-bus module is connected with the emergency lighting controller. The fire-protection emergency sign lamp provided by the invention is advantageous in safety, reliability and reduction of the possibility of electric leakage-caused wounding, and can indicate escape routes according to on-site actual situations, and more effectively realize the effect of fire-protection emergency signs.

Description

technical field [0001] The invention discloses a fire emergency sign lamp, in particular to a fire emergency sign lamp with centralized power supply and centralized control, which belongs to the field of emergency sign lamps. Background technique [0002] Fire emergency sign lights provide escape routes for people to escape when a fire occurs. However, traditional evacuation emergency sign lights exist as isolated monomers in buildings, and cannot respond to changes in the fire scene, let alone dynamically adjust the escape direction. Instructions will bring difficulties to escape from the scene. The traditional emergency sign lamps are powered by AC220V. When a fire breaks out, firefighters are prone to electric leakage and electric shock when they extinguish the fire. In addition, there is a serious hysteresis in the daily maintenance and repair of traditional emergency sign lights. The main function of emergency sign lights is to start an emergency in case of fire, and t...

[0002] Fire emergency sign lights provide escape routes for people to escape when a fire occurs. However, traditional evacuation emergency sign lights exist as isolated monomers in buildings, and cannot respond to changes in the fire scene, let alone dynamically adjust the escape direction. Instructions, making it difficult to escape from the scene

The traditional emergency sign lamps are powered by AC220V. When a fire breaks out, firefighters are prone to electric leakage and electric shock when they extinguish the fire.

In addition, there is a serious hysteresis in the daily maintenance and repair of traditional emergency sign lights. The main function of emergency sign lights is to start an emergency in the event of a fire, and the key to starting an emergency is whether the battery charge and discharge work normally.

Relying on manpower maintenance and inspection, product problems cannot be found in time, and its reaction is that in the event of a fire, it often brings many blind spots to the escape and evacuation instructions of the building

Such application status can no longer meet the requirements of modern large buildings
