Technical Field

As a result, rail transit operation and management companies in various places usually adopt the method of training sharpshooters in the military to train drivers - "using bullets to pile up", which often means that companies need to bear extremely high training costs. Especially in recent years, with the rapid development of rail transit signal systems, manned unmanned lines have been widely built. The skill of manual driving is in an embarrassing situation of "no practice in normal times, but needed in emergencies". Operation and management companies in various places are looking forward to an optical driving aid device that can be used in rail transit systems to achieve a low-cost solution.

A light source panel can be movably installed inside the installation space. The light source panel can emit scattered light sources of different colors, which are incident through the plane of the lens assembly 7 and then output through the uneven surface to form a parallel light area.

The A light source panel is arranged inside the component housing 1 to form an A optical imaging component, the B light source panel is arranged inside the component housing 1 to form a B optical imaging component, and the C light source panel is arranged inside the component housing 1 to form a C optical imaging component. The A optical imaging component, B optical imaging component, and C optical imaging component can select the installation direction and the installation quantity of various colored lights according to the installation position conditions, and are combined to form an optical driving assistance imaging device; the optical driving assistance imaging device is arranged beside the rail transit line; by erecting an optical driving assistance imaging device with multiple groups of optical imaging components as the core and different color signals as the command and installed with Fresnel lenses beside the traffic track, the yellow optical imaging component 3, green optical imaging component 4, and red optical imaging component 5 respectively emit multiple layers of light beam areas perpendicular to the ground, maintaining a certain angle with the traffic track line and intersecting. Among them, the light beam in the under-marked area for parking is yellow, the light beam in the on-marked area for parking is green, and the light beam in the over-marked area for parking is red. In the manual driving mode, it is convenient for the driver to manually drive the train to align and park, further improving the alignment accuracy of manual alignment and parking, enabling the driver to quickly master the accurate alignment skills, and saving a great deal of time cost and train operation and maintenance cost compared with the traditional mode.
[0022] In this embodiment, the A optical imaging component is the yellow optical imaging component 3, which can emit a yellow light beam perpendicular to the ground and intersecting the traffic track line at a certain angle, forming a yellow area for under-standard parking; the B optical imaging component is the green optical imaging component 4, which can emit a green light beam perpendicular to the ground and intersecting the traffic track line at a certain angle, forming a green area for on-standard parking; the C optical imaging component is the red optical imaging component 5, which can emit a red light beam perpendicular to the ground and intersecting the traffic track line at a certain angle, forming a red area for over-standard parking; the reference lamp 8 is a green lamp, which is installed in the chute provided on the component housing and can slide relatively on the component housing according to the angle and position requirements; when the vehicle is moving on the traffic track line, if the driver sees the yellow light beam of the optical phenomenon component, it means that the parking position is about to be reached, and the driver can adjust the speed and brake in advance according to the relative position between the yellow light beam and the green reference lamp 8; if the driver sees the green light beam of the optical phenomenon component and it is in the same straight line as the green reference lamp 8, it means that the vehicle has reached the parking position; if the driver sees the red light beam of the optical phenomenon component and the red light beam has crossed the green reference lamp 8, it means that the vehicle has crossed the parking position, and the vehicle should stop immediately. Installing this device near the locomotive parking position can help drivers without a lot of training to drive the locomotive to achieve safe and accurate on-standard parking at this place.
[0023] In this embodiment, the A light source panel, B light source panel, and C light source panel all adopt light sources with a narrow light-emitting surface, including LED light strips 6 or side light optical fibers; when in use, the LED light strips 6 emit yellow, green, and red light beams. After the light beams are incident from the plane of the Fresnel lens and then output from the ridged surface of the Fresnel lens, yellow, green, and red parallel light regions are respectively formed, which is convenient for the driver to manually drive the train for on-standard parking, further improving the on-standard accuracy of manual on-standard parking. Moreover, according to the small-angle light scattering degree that the optical assistance imaging device of the Fresnel lens can achieve and the change in the installation position beside the track, this device can achieve light indication within a range of ±100 mm, and can eliminate the parking position error caused by changes in the driver's height, sitting posture, and position, etc.; in this embodiment, the light beams emitted by the LED light strips 6 can also be other colors such as blue, black and white, and color, etc., to achieve the light indication function that is convenient for the driver to manually drive the train for on-standard parking and further improve the on-standard accuracy of manual on-standard parking.
[0024] In this embodiment, after the light beam is incident from the plane of the Fresnel lens and then output from the ridged surface of the Fresnel lens, yellow, green, and red parallel light regions are respectively formed. This is the application of the beam collimation function of the Fresnel lens. As long as the point light source is placed at its focal point, an objective collimated light output can be obtained, which is exactly the opposite of large-area light collection. The Fresnel lens can also well emit the incident point light source into a parallel light region.
[0025] In this embodiment, a power supply compartment 2 is provided on the component housing, and a power supply module is built therein to supply electrical energy to the electrical components in the optical driving assistance device and ensure its normal operation.

Among them, the light beam in the under-marked parking area is yellow, the light beam in the on-marked parking area is green, and the light beam in the over-marked parking area is red. When the vehicle travels on the traffic track line, if the driver sees the yellow light beam of the optical imaging component, it means that the vehicle is about to reach the parking position, and the driver can adjust the speed and brake in advance according to the relative position between the yellow light beam and the green reference lamp 8; if the driver sees the green light beam of the optical imaging component and is on the same straight line as the green reference lamp 8, it means that the vehicle has reached the parking position; if the driver sees the red light beam of the optical imaging component and the red light beam crosses the green reference lamp 8, it means that the vehicle has crossed the parking position and should stop immediately. In the manual driving mode, it is convenient for the driver to manually drive the train to perform alignment parking, further improving the alignment accuracy of manual alignment parking, enabling the driver to quickly master the precise alignment skills, and saving a great deal of time cost and train operation and maintenance cost compared with the traditional mode.
