Traffic accidents caused by traffic violations often occur, causing huge losses to individuals and society. In some large or provincial capital cities, traffic conditions have even become a major event related to the national economy and people's livelihood, so it is urgent to solve the problem of traffic violations. Most of the current crosswalks are composed of crosswalk lights (red, yellow, green or traffic lights) and zebra crossings. Pedestrians and vehicles use simple signal lights to determine whether to pass or wait, thereby ensuring smooth and safe traffic.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0019] See also Figure 1-Figure 3 The utility model provides a technical solution: an intelligent pedestrian crossing warning system, including a supporting metal frame 1, an extension plate 12, a projection screen 6, a 3D projector 5 and a controller 9. A high-strength cross frame 15 is horizontally fixed on the upper end of the supporting metal frame 1. Two 3D projectors 5 are arranged, and the two 3D projectors 5 are staggeredly installed on the front and rear sides of the supporting metal frame 1. Two projection screens 6 are arranged. A dismantling plate 8 is installed on the upper side of the front end of the supporting metal frame 1 by bolts, and a controller 9 and a language announcer 10 are installed inside the dismantling plate 8. The right end of the high-strength cross frame 15 is horizontally fixed with an extension plate 12 by two reinforcing diagonal rods 11 and a reinforcing strip plate 13, and light blocking plates 14 are installed on the front and rear sides of the lower end of the extension plate 12.
[0020] As the first embodiment of the utility model: the lower sides of the front and rear ends of the supporting metal frame 1 are horizontally welded with reinforcing plates 2. The added reinforcing plates 2 facilitate the stable installation of the front and rear ends of the supporting metal frame 1 at the crosswalk. The upper ends of the two reinforcing plates 2 are penetrated by fastening bolts 4, and the upper ends of the two reinforcing plates 2 are obliquely welded with multiple reinforcing ribs 3. The added fastening bolts 4 enable the two reinforcing plates 2 to be installed and fixed on both sides of the crosswalk, and the welding arrangement of multiple reinforcing ribs 3 makes the connection strength of the two reinforcing plates 2 and the front and rear ends of the supporting metal frame 1 higher.
[0021] Two projection screens 6 are installed in a staggered manner on the front and back sides of the supporting metal frame 1, and the two projection screens 6 are facing the projection ends of the two 3D projectors 5. Warning projection symbols 7 are projected on the surfaces of the two projection screens 6. The two added projection screens 6 can display the warning projection symbols 7 projected by the projection ends of the two 3D projectors 5, so that pedestrians on both sides can observe the warning projection symbols 7 projected on the two projection screens 6, thereby achieving the purpose of warning them. A honeycomb hole is provided on the lower side of the front end of the dismantling plate 8. The added honeycomb hole facilitates the external volume intensity of the language announcer 10. The controller 9, the language announcer 10, the two 3D projectors 5 and the external traffic light circuit board are connected by wires. The added controller 9 can control the two 3D projectors 5 and the language announcer 10 to work synchronously with the external traffic light when the red light is on by programming.
[0022] As the second embodiment of the utility model: the added reinforcement plate 2 facilitates the stable installation of the supporting metal frame 1 at the crosswalk, the fastening bolts 4 enable the two reinforcement plates 2 to be installed and fixed on both sides of the crosswalk, and the welding arrangement of multiple reinforcing ribs 3 makes the connection strength between the two reinforcement plates 2 and the front and rear ends of the supporting metal frame 1 higher, and the design of the extension plate 12 and the light shielding plate 14 can prevent sunlight from affecting the 3D projection effect of the two projection screens 6, and can also shield pedestrians from light and rain, thereby greatly improving the practicality of the device. When the red light of the external traffic light turns on, the controller 9 controls the two 3D projectors 5 to work through programming, and the two 3D projectors 5 can project the warning projection symbols 7 on the two projection screens 6 through mature projector principle technology for pedestrians to observe. At the same time, the controller 9 will also control the language broadcaster 10 to broadcast the language, thereby warning the pedestrians at the crosswalk.
