At present, the number of Chinese-style roads is very large, many pedestrians do not obey the traffic rules on the zebra crossing (pedestrian crossing), and the phenomenon of civilization such as running red light often occurs, and in many places, traffic polices or police assistants often stand on the edges of the zebra crossing, and small flags in hands or blow whistles remind the pedestrians to pay attention to the traffic lights, do not run the red light at random, and obey the traffic rules.
The patent of application publication No. CN104314023, Zebra crossing intelligent guardrail, discloses a plastic guardrail, when the red light, the guardrail is put down to block the pedestrian; when the green light, the guard rail is opened, and pedestrians can pass.
The patent of application publication No. CN105603912, a high-efficiency intelligent guardrail for zebra crossing, discloses a target identification device, which can effectively filter the target contour noise in the identification process by identifying the target contour, thereby judging pedestrians and vehicles. The patent of application publication No. CN105672173, "a zebra crossing intelligent guardrail with recognition function", discloses that a millimeter wave radar three-dimensional environment perception system is additionally arranged on a guardrail.

Furthermore, the sound module is placed in the control cabinet, and a plurality of sound outlet holes are formed in the wall of the control cabinet corresponding to the sound outlet positions of the sound module.
The operation principle of the zebra crossing shadow eliminating guardrail of the invention is as follows:
the fog screen module 2 is fixedly arranged near the starting point of a zebra crossing of a sidewalk, the holographic projection module 3 is fixed on one side of a pedestrian crossing far away from a road, and the sound module 6 is arranged near the fog screen module 2, so that synchronous matching of images and sound is facilitated; the fog screen module 2, the holographic projection module 3 and the sound module 6 are independently connected with an external power supply and are connected with the control module 1 through control signal lines, the communication and data transmission module 4 and the storage module 5 are electrically connected with the control module 1, and the control module 1 is connected with an external power supply through a power supply module 7.
The communication and data transmission module 4 receives external signals or data, if the received external control signals are sent to the control module 1, the control module 1 performs unified control, and if the received external control signals are received, the received external control signals are stored in the storage module 5 through the control module 1. The data are holographic image data, and can be uniformly sent to the communication and data transmission modules 4 of the zebra crossing information guardrails through corresponding management backstage after being recorded in a professional camera shed in a data transmission mode, and are stored in the storage module 5, or are directly copied to the storage module 5 through the communication and data transmission modules 4.
In an external signal mode, when the communication and data transmission module 4 receives a red light control signal, the control module 1 sends a starting command to the fog screen module 2 and the holographic projection module 3, after the fog screen module 2 receives the starting command, the fog screen generating device 22 generates a large amount of fog, the fog is conveyed to the fog discharging device 24 through the fog discharging pipe 23, the fog discharging device 24 generates uniform fog screens 25 from the fog, meanwhile, the holographic projection module 3 holographically projects data (such as traffic police image data) specified by the storage module 5 onto the fog screens 25 to form lifelike holographic images 34, and if the holographic data are matched with sound data, the control module 1 simultaneously controls the sound module 6 to synchronously play sound; when the communication and data transmission module 4 receives the green light control signal, the control module 1 sends a stop command, and simultaneously stops the operation of the fog screen module 2, the holographic projection module 3 and the sound module 6, so that the holographic imaging 34 disappears, and pedestrians pass through the road; of course, the control module 1 may also be configured to control the working time, the projection content, the playing sound, and the like of the fog screen module 2, the holographic projection module 3, and the sound module 6 when the communication and data transmission module 4 receives other control signals such as a yellow light.
Because there is a certain distance between the fog screen module 2 and the holographic projection module 3, in order to prevent the projection light from being blocked by the pedestrian, certain constraint conditions should be satisfied, as shown in fig. 4: the height H fixed by the holographic projector is equal to or greater than hd2/d1, the distance d2 from a vertical projection point of the holographic projector on the ground to the fog screen, the height H of all local people, the distance d1 from a warning line position where the pedestrian stands to the fog screen are fixed, and if the distance d1 is fixed and cannot be changed; if the fixed height H of the holographic projector cannot be changed, the distance d1 between the position where the warning line is arranged and the fog screen should be greater than or equal to hd 2/H.
In a first embodiment of the invention shown in fig. 2, the mist discharge device 24 is a cross-flow fan, because: 1. the cross flow fan has uniform wind speed distribution and low interference, and can send far fog under the condition of low noise; 2. the air flow at the air outlet is distributed more uniformly along the axial direction; the combination of the two points is that a relatively stable fog screen with larger axial direction and transverse direction can be formed.
In the second embodiment of the present invention shown in fig. 2, the sound module 6 should be placed close to the holographic image 34 to have a sense of reality, or to have a sense of incongruity in sound and shape, considering the distance between the fog screen module 2 and the holographic projection module 3. Therefore, the sound module 6 is placed in the fog screen control cabinet 21 to play a certain protection role of rain protection and sun protection, and in order to facilitate the transmission of sound, a plurality of sound outlet holes 211 are formed in the wall of the control cabinet corresponding to the sound outlet position of the sound module 6.
In the third embodiment of the present invention shown in fig. 3, since the holographic projector is required to have a certain height and a certain distance to the fog screen, and is required to be firm and safe, the supporting device is selected from metal materials and shapes similar to pole street lamps, and is preferably linear (as shown in fig. 3-a) and inverted L-shaped (as shown in fig. 3-b). The linear and inverted L shapes are selected depending on the constraint conditions shown in fig. 4, and if the calculated height is not reasonable when the linear support device is selected, the inverted L shape should be selected, and the value of H should be changed by changing the size of d2, so that the reasonable height of the support device is selected.
As shown in fig. 5, a third embodiment of the present invention is that, in this embodiment, the projection module 3 and the fog screen module 2 are installed on a sidewalk on the same side of a road, in this embodiment, the fog screen module 2 is installed on the side of the sidewalk near the road, and the projection module 3 is installed on the side of the sidewalk far from the road.
As shown in fig. 6, in a fourth embodiment of the present invention, in this embodiment, the projection module 3 and the fog screen module 2 are installed on a sidewalk on both sides of a road, in this embodiment, the fog screen module 2 is installed on one side of the sidewalk close to the road, and the projection module 3 is installed on one side of the sidewalk close to the road or far from the road on the other side of the road.
