Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, this utility model is expanded on further.
The utility model proposes a kind of based on the subway carriage LED illumination System being wirelessly transferred, be used for solving
The transform measure of LED illumination is used in subway carriage.It is photosensitive that native system includes being arranged in subway carriage
Resistance, the described photoconductive resistance in the more piece compartment of same joint or same section is connected to control chamber, controls
Including photoconductive resistance signal analog to digital conversion circuit and comparison circuit in case, comparison circuit connects wireless output mould
Block, also includes the current supply circuit to each circuit and module for power supply, is arranged in subway carriage in control chamber
LED illumination lamp group is provided with wireless receiving module, and described control chamber shines by being wirelessly transferred the described LED of control
The drive circuit of bright lamp group, changes the brightness of illumination of described LED illumination lamp group, and described photoconductive resistance is arranged
At lifting rails top, compartment or carriage handle crossbeam or car body top.Accompanying drawing 1 is system of the present utility model
System schematic diagram.
The investigative range of described photoconductive resistance is set greater than equal to 3 meters, the ambient light in this investigative range
Can be captured by photoconductive resistance by force, such illuminance collection design is possible not only to supervise more accurately
Measure illuminance in compartment, it is also possible to save the arrangement quantity of photoconductive resistance so that monitor simpler side
Just.
