Embodiment 1

[0026] Light source control system for dual-stream rail trains, such as figure 1 Shown: It includes positioning module, main light source module, auxiliary light source module and control module. The positioning module sends real-time location information of the train to the control module. The positioning module can use the existing GPS positioning module. The main light source module The center of the top of the train carriage is illuminated, and the auxiliary light source module is illuminated from the sides of the main light source module near the window sash. The main light source module and the auxiliary light source module can use existing LED lighting modules; the control module acquires environmental information according to the location information , the control module can use the existing SOC chip, and the control module controls the light intensity of the main light source module and the auxiliary light source module to reduce according to the environmental informat...

Embodiment 2

[0033] The difference with Embodiment 1 is that, if figure 2As shown, the auxiliary light source module includes a rotating motor 3 fixedly installed on the inner wall of the compartment by screws, a rotating seat 4 is welded on the output shaft of the rotating motor 3, and an auxiliary light source 6 is clamped on the top surface of the rotating seat 4. A vertical seat 7 is welded on the top of the seat 4, and a downwardly inclined reflector 5 is bonded to the top of the vertical seat 7, and the reflector 5 is located above the auxiliary light source 6. The reflector 5 is L-shaped, and the reflector 5 The horizontal section of the reflector 5 is welded on the vertical seat 7, the horizontal section of the reflector 5 is a light-transmitting section, the inner angle of the reflector 5 is 120°, and the inclination angle of the reflector 5 is set according to actual needs; There is a light-transmitting plate 8, and the light-transmitting plate 8 is positioned at the end face of...

Embodiment 3

[0036] The difference with Embodiment 2 is that the control module compares the adjustment distance with the preset value when it judges that there is no lighting outside the train according to the preset position, and the preset value is the length value of a shorter tunnel, for example, the preset value is set to 200 m, when the adjustment distance is less than the preset value, the control module controls the light intensity of the main light source module and the auxiliary light source module to not change.

[0037] When there is no light in the tunnel, first judge the length of the adjustment distance of the tunnel. When the adjustment distance is small, the light intensity of the main light source module and the auxiliary light source module will not be changed to avoid the light intensity of the main light source module and the auxiliary light source module. Adjusting too often can cause damage.

Abstract

The invention relates to the technical field of lighting control, and particularly relates to a light source control system of a double-current system rail train. The system comprises a positioning module, a main light source module, an auxiliary light source module and a control module. The positioning module positions the position information of the train in real time and sends the position information to the control module; the control module acquires environment information according to the position information; the control module enables a light intensity change of the main light source module and the auxiliary light source module according to the environment information, and the light intensity change amplitude of the main light source module is larger than that of the auxiliary light source module; and the control module judges whether the light outside a carriage changes from bright to weak according to the position information, and if so, the control module enables the light of the main light source module to be reduced and the light of the auxiliary light source module to be increased according to the light change. The internal light intensity is adjusted in time according to the environment outside the carriage, and the comfort level of passengers is improved.

Description

technical field [0001] The invention relates to the technical field of lighting control, in particular to a light source control system for a dual-stream rail train. Background technique [0002] Dual-stream trains are vehicles that travel across two different power supply areas. Dual-stream trains are mostly used in areas with long mileage and complex road conditions. Dual-stream trains may pass through tunnels and open-air tracks back and forth during driving. , resulting in light and dark changes in the dual-stream trains, causing discomfort to passengers. [0003] Aiming at the problem of light in dual-stream trains, the patent with the publication number CN108749840A discloses a rail vehicle lighting and intelligent display control system and method. Module and side light belt, the hub module is used to control the playback content of the center roof display module and the lighting adjustment of the side light belt. Among them, the hub module includes a control panel, ...
