Problems solved by technology

[0002] In the substation control room or high-voltage switch room of the power system, emergency evacuation devices are generally installed to indicate the direction of emergency evacuation passages in case of fire. This kind of emergency evacuation devices mostly use 220V mains for power supply, and the emergency evacuation devices are in Always on, resulting in a waste of power
[0003] In addition, this traditional emergency evacuation device can only indicate the direction of the evacuation passage in the event of a fire, and cannot achieve the functions of early warning and warning staff, and the use effect is poor

Abstract

The invention provides an emergency exit indicating device, belongs to the technical field of safety protection, and solves the technical problem that the emergency exit indicating device which saves electric energy and performs sound-light prompting for work personnel in the early stage of fire is provided. The adopted technical scheme is the emergency exit indicating device comprising a box body. The front panel of the box body is provided with an evacuation mark. The box body is internally provided with a circuit board. The circuit board comprises a power supply unit, a light-sensitive unit, a control unit, a voice alarm unit, an LED display unit and a fire alarm controller. The signal output end of the light-sensitive unit is connected with the signal input end of the LED display unit. The signal input end of the control unit is connected with the signal output end of the fire alarm controller. The signal output end of the control unit is connected with the signal input end of the LED display unit and the signal input end of the voice alarm unit. The emergency exit indicating device is suitable for the field of electric power.

Description

technical field [0001] The emergency exit indicating device of the invention belongs to the technical field of safety protection. Background technique [0002] In the substation control room or high-voltage switch room of the power system, emergency evacuation devices are generally installed to indicate the direction of emergency evacuation passages in case of fire. This kind of emergency evacuation devices mostly use 220V mains for power supply, and the emergency evacuation devices are in Always on, resulting in a waste of power. [0003] In addition, this traditional emergency evacuation device can only indicate the direction of the evacuation passage in the event of a fire, and cannot achieve the functions of early warning and warning staff, and the use effect is poor. [0004] Therefore, it is particularly important to have an emergency exit indicating device that can give sound and light prompts to the staff at the initial stage of a fire and notify the staff of emerge...
