Novel subway carriage light intelligent control system

Abstract

The invention provides a novel subway carriage light intelligent control system, and the system comprises: a human body detection module which is used for detecting a human body signal in a subway carriage and outputting a first signal; an external illumination detection module which is used for detecting and outputting real-time illumination intensity; an arrival detection module which is used for outputting a second signal; and a central control system which is used for controlling the compartment lamp group module to be lightened at the first brightness and output a third signal when receiving the second signal, and controlling human body signal detection and outputting a fifth signal when not receiving the second signal or receiving the third signal, processing to obtain the second brightness, controlling the compartment lamp group module to be lightened at the second brightness, outputting a sixth signal when judging that the time interval between the current moment and the moment when the first signal is received finally is less than the preset time, controlling to turn off the lamp when the time interval is not less than the preset time, and controlling to carry out real-time illumination intensity detection according to the fourth signal or the sixth signal. The beneficial effects are that energy waste caused by light air switch is avoided, and the service time of the lamp group in the subway can be effectively controlled.

Description

technical field [0001] The invention relates to the field of lighting control, in particular to a novel intelligent control system for lighting in subway cars. Background technique [0002] The current subway car lighting control system uses a simple on and off method to control the lights in the subway car. According to the requirement of light brightness in different situations, using the traditional system can save little power, and it is not ideal for the detection of people in the compartment, and manual control is difficult to achieve good results. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a new intelligent control system for lighting in subway cars, including: [0004] A plurality of human body detection modules are respectively arranged on the top inner wall of a subway car for detecting the human body signal in the subway car, and outputting a first signal when the human body signal indicat...
