本发明的最佳实施方式BEST MODE FOR CARRYING OUT THE INVENTION
图像帧控制技术主要是在增加显示光柱密度基础上，采用随动顺序帧同步控制技术，逐个显示光柱依次确定显示起点并与列车运动同步，从而使显示图像依顺序点亮并相互叠加，使多显示的帧数增加，避免产生闪烁现象。包括随动帧同步技术、统一帧同步技术和闭合增帧技术。The image frame control technology mainly adopts the follow-up sequence frame synchronization control technology on the basis of increasing the density of the display light column. The display light column is sequentially displayed one by one to determine the display starting point and synchronize with the train motion, so that the display images are sequentially lit and superimposed on each other, so that The number of displayed frames is increased to avoid flicker. It includes follow-up frame synchronization technology, unified frame synchronization technology and closed frame-increasing technology.
下面结合附图对本发明作出详细的说明。The invention will now be described in detail in conjunction with the drawings.
如图1所示，本发明提供的用于隧道运动图像显示的图像帧控制技术包括以下步骤：As shown in FIG. 1, the image frame control technique for tunnel moving image display provided by the present invention includes the following steps:
A10、在隧道上依次并排设置多个显示光柱，相邻两个显示光柱之间间隔一定距离，显示光柱接收帧控制器发出的帧同步信号；A10. A plurality of display beams are arranged side by side in the tunnel, and a distance between the adjacent two display columns is displayed, and the frame synchronization signal sent by the frame receiving frame controller is displayed;
A20、帧控制器记录每个显示光柱的坐标，并根据机车运行速度计算每个显示光柱的帧同步信号的发出时间；A20. The frame controller records the coordinates of each display light column, and calculates the time of sending the frame synchronization signal of each display light column according to the running speed of the locomotive;
A30、列车依次经过显示光柱时，帧控制器相应的向该显示光柱发出帧同步信号，该显示光柱开始以其为起点扫描一帧的1-n列显示数据，从而实现多帧图像与列车同步且依次显示形成运动图像；A30. When the train passes through the display beam in sequence, the frame controller sends a frame synchronization signal to the display beam, and the display beam starts to scan the 1-n column display data of one frame as the starting point, thereby realizing multi-frame image and train synchronization. And sequentially displaying a moving image;
A40、如列车低速运行，为消除图像闪烁可在相邻的两个显示光柱之间增加若干个显示光柱，然后依次重新设置帧控制器，计算每个显示光柱的帧同步信号的发出时间。列车在低速运行时，机车外显示图像帧频率相应降低，导致闪烁现象，通过增加显示光柱密度的方法可以提高显示帧数，消除闪烁感，提高显示质量。A40. If the train runs at a low speed, in order to eliminate the image flicker, several display beams can be added between the adjacent two display beams, and then the frame controllers are sequentially reset to calculate the time of the frame synchronization signal of each display column. When the train is running at low speed, the image frame frequency displayed outside the locomotive is correspondingly reduced, resulting in flickering. By increasing the density of the display beam, the number of display frames can be increased, the flickering feeling can be eliminated, and the display quality can be improved.
上述方法可以称为随动帧同步技术，随动帧同步技术可以随意增加光柱数量，安装距离也可不一致，当均匀布置光柱时可使设计简单和易于实现，并取得较好加帧效果，但是位置的随意性使得更加易于安装。在随动帧同步技术中，第N个显示光柱帧同步与N-1个显示光柱帧同步的间隔时间：The above method can be called follow-up frame synchronization technology, and the follow-up frame synchronization technology can increase the number of light columns at will, and the installation distance can also be inconsistent. When the light column is evenly arranged, the design can be simple and easy to implement, and a good frame-adding effect is obtained, but The randomness of the location makes it easier to install. In the follow-up frame synchronization technology, the interval between the Nth display beam frame synchronization and the N-1 display beam frames is synchronized:
ΔT=L/VΔT=L/V
其中L为第N个光柱距第N-1个光柱距离,V为列车速度。Where L is the distance between the Nth light column and the N-1th light column, and V is the train speed.
本发明的实施方式Embodiments of the invention
另一种用于隧道运动图像显示的图像帧控制技术称为统一帧同步技术，包括以下步骤：Another image frame control technique for tunneling motion image display is called unified frame synchronization technology and includes the following steps:
B10、在隧道上依次并排设置多个显示光柱，相邻两个显示光柱之间间隔一定距离，显示光柱接收帧控制器发出的同一帧同步信号；B10. A plurality of display light columns are sequentially arranged side by side on the tunnel, and a distance between adjacent two display light columns is displayed, and the same frame synchronization signal sent by the light column receiving frame controller is displayed;
B20、多个显示光柱同时开始以其为起点扫描一帧的1-n列显示数据，从而实现多帧图像的显示，列车依次经过显示光柱时形成运动图像；B20, the plurality of display beams simultaneously start scanning the 1-n column display data of one frame with the starting point thereof, thereby realizing display of the multi-frame image, and the train forms a moving image when passing through the display light column;
B30、如列车低速运行，为消除图像闪烁可在相邻的两个显示光柱之间增加若干个显示光柱，设一个增加的显示光柱位于前一个显示光柱的扫描图像的x+1列，则该增加的显示光柱以其为起点从x+1列开始扫描，从而使每个显示光柱开始扫描的图像实现无接缝的嵌套。B30. If the train is running at a low speed, in order to eliminate image flicker, a plurality of display light columns may be added between two adjacent display light columns, and an increased display light column is located in the x+1 column of the scanned image of the previous display light column. The added display beam starts scanning from the x+1 column with it as a starting point, thereby enabling seamless nesting of the image that each of the display beams begins to scan.
闭合增帧技术是指在随动帧同步技术和统一帧同步技术中，相邻两个显示光柱之间的距离等于图像宽度，增加的一个显示光柱位于上述相邻两个显示光柱之间的中点位置，且增加的相邻两个显示光柱之间的距离也等于图像宽度。The closed frame-increasing technique means that in the follow-up frame synchronization technology and the unified frame synchronization technology, the distance between two adjacent display beams is equal to the image width, and an added display beam is located between the adjacent two display columns. The point position, and the distance between the adjacent two adjacent display beams is also equal to the image width.
闭合加帧技术的帧同步可以是随动的，也可以是同一的，增加的显示光柱在标准光柱之间的插入是可以任意的，现场安装时可根据设备情况调整间距。增加的一个显示光柱位于原有相邻两个显示光柱之间的中点位置时，具有最佳效果，如图2所示，只要保证L1+L2=W即可（W为图像宽度），在L1=L2=1/2•W时具有最佳效果，所以L1和L2不应相差太多。闭合加帧技术使得各个显示光柱的显示图像严格闭合，从而具有更好的亮度均匀性，避免闪烁现象。在多显示光柱插入时，只要保证其分布均匀，且间距为图像宽度W即可以实现严格的封闭嵌套。The frame synchronization of the closed frame-adding technique can be either follow-up or the same. The insertion of the added display beam between the standard beams can be arbitrary, and the spacing can be adjusted according to the equipment condition during field installation. The added one of the display beams has the best effect when it is located at the midpoint between the two adjacent display beams. As shown in Figure 2, as long as L1+L2=W is guaranteed (W is the image width), L1=L2=1/2•W has the best effect, so L1 and L2 should not be too different. The closed frame-adding technique makes the display image of each display light column strictly closed, thereby having better brightness uniformity and avoiding flicker. When multiple display beams are inserted, strict closed nesting can be achieved as long as the distribution is uniform and the pitch is the image width W.
本发明不局限于上述最佳实施方式，任何人应该得知在本发明的启示下作出的结构变化，凡是与本发明具有相同或相近的技术方案，均落入本发明的保护范围之内。The present invention is not limited to the above-described preferred embodiments, and any one skilled in the art should be aware of the structural changes made in the light of the present invention. Any technical solutions having the same or similar to the present invention fall within the protection scope of the present invention.
