Problems solved by technology

However, since any contactor in the existing subway station lighting system will turn on all the LED lights in the corresponding lighting circuit, it cannot emit light according to the actual lighting conditions of the environment where the LED lights are located and the operating conditions of the subway. Intensity adjustment is easy to cause waste of energy consumption

Abstract

The invention discloses a lighting system of a subway station. The system comprises a central controller, a gateway connected with the central controller, a first illuminance sensor, a first infraredsensor, a timer and a first DALI gateway. The first illuminance sensor, the first infrared sensor, the timer and the first DALI gateway are connected with the gateway, and the first DALI gateway is connected with a first LED lamp set, a second LED lamp set and a third LED lamp set. The central controller is used for dimming the luminous intensity of the first LED lamp group according to the firstillumination information, enabling all LED lamps in the second LED lamp group to emit light according to the passenger action information, and dimming the luminous intensity of the LED lamps on the suspended ceiling, located at the shutdown ticket checker, in the third LED lamp group according to the shutdown mode. The lighting intensity can be adjusted according to actual environment illuminationand subway operation, lighting energy consumption is reduced, and passengers can be guided to go out through lighting.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a lighting system for a subway station. Background technique [0002] At present, the lighting system of subway stations in most cities in my country includes two modes: normal lighting and power-saving lighting, such as figure 1 As shown, the existing subway station lighting system is mainly composed of BAS (Building Automation System, building automation system) system 1, PLC (Programmable Logic Controller, referred to as PLC) controller 2, first contactor 3, normal lighting circuit 4, second The two contactors 5 and the power-saving lighting circuit 6 are composed, wherein the PLC controller 2 is used to monitor the first contactor 3 and the second contactor 5 according to the instruction of the BAS system 1, and then realize the on-off control of the lighting circuit. However, since any contactor in the existing subway station lighting system will turn on all the LED lights...
