As shown in fig. 3, 4 and 5, the deceleration control mechanism 42 includes a connecting rotating column 421, a plurality of deceleration strips 422 connected with one end of the warning deceleration way 411 close to the upper longitudinal way 2 of the overpass, and a plurality of speed regulation strips 423 connected with one end of the unidirectional traffic way 412 far away from the warning deceleration way 411, a step block 424 for blocking the deceleration strips 422 is arranged on the warning deceleration way 411, a pushing block 425 is connected in the step clamping block 424 in a sliding way, a plurality of deceleration strips 426 used for limiting the pushing block 425 are connected on the inner wall of the bottom of the step clamping block 424, the inner side wall of the stepped clamping block 424 is provided with a sliding caulking groove 427 for limiting the pushing block 425, the pushing block 425 is connected with the deceleration strip 422 through a connecting rotating column 421, one side surface of the pushing block 425 is provided with a driving pushing tooth column 428 for pushing the limiting guide mechanism 43 to move, and the other side surface of the pushing block 425 is provided with a reset column 429.
In order to achieve the purpose of speed reduction and prevent the vehicle from turning and colliding with the vehicle behind due to the fact that the vehicle is uncomfortable to turn quickly in the driving process, in the specific implementation, once the vehicle enters the warning deceleration way 411, the vehicle gradually contacts the deceleration strip 422 and presses the deceleration strip 422, the deceleration strip 422 is directly moved towards the inside of the step clamping block 424 after being pressed, then the movable deceleration strip 422 pushes the connecting rotation columns 421 to move together, the movable connecting rotation columns 421 push the pushing blocks 425 to move towards the side far away from the resetting columns 429, fig. 4 shows that the two pushing blocks 425 are pushed by the deceleration strip 422 to move in the directions far away from each other, and then the movable pushing blocks 425 slide along the sliding caulking grooves 427, so that the situation that the pushing blocks 425 are tilted and deflected does not easily occur.
The pushing block 425 pulls the reset column 429 to move in the moving process, so that the reset column 429 is compressed to facilitate the subsequent resetting operation of the pushing block 425, meanwhile, the pushing block 425 can push the driving pushing tooth column 428 to move in the moving process, the driving pushing tooth column 428 can push the limiting guide mechanism 43 to move to gradually enlarge the limiting guide mechanism 43 in the moving process, and the driving pushing tooth columns 428 are provided with a plurality of driving pushing tooth columns, so that the limiting guide mechanism 43 can be fully enlarged, and then a vehicle can directly slide into the one-way lane 412 through the limiting guide mechanism 43.
As shown in fig. 4, the return column 429 includes a return pull column 4291 connected to the push block 425 and having a "T" shape, and a shift plate 4292 sleeved on a side wall of the return pull column 4291 and connected to an inner wall of the step locking block 424, and a return push spring 4293 whose end is connected to the shift plate 4292 is sleeved on a side wall of the return pull column 4291.

The pressure receiving spring 4234 includes a partition plate 4237 mounted on the inner wall of the mounting cover 4231 and a partition spring 4238 for being divided into a pressing section and a releasing section by the partition plate 4237, and a partition hole 4239 for accommodating the partition spring 4238 is opened in the partition plate 4237.
In the present embodiment, the partition hole 4239 divides the partition spring 4238 into a compression section and a release section, as shown in fig. 6, wherein the compression section is one section of the partition spring 4238 in a compressed state, and the release section is one section of the partition spring 4238 connected to the lifting block 4233 and in a relaxed state, and then, the lifting block 4233 is compressed to compress only the release section without pressing the compression section, and if the thrust of the compressed spring 4234 needs to be adjusted, only the partition spring 4238 is rotated to make the length of the release section longer.
In order to realize the operation of decelerating the vehicle in the one-way lane 412, when the vehicle slides in the one-way lane 412, if the vehicle slides into the lower cross lane 1 of the overpass, the vehicle needs to move from top to bottom, so that the vehicle can be decelerated by the speed adjusting belt 423, the vehicle can smoothly slide into the one-way lane 412 without contacting with the vehicle in the lower cross lane 1 of the overpass to collide with the vehicle, in the embodiment, as shown in fig. 6, the pressing sheet 4232 is inclined, so that the one-way movement of the vehicle can be met, and the vehicle does not move from bottom to top from the one-way lane 412.
When the speed regulation belt 423 is used specifically, once a vehicle directly presses the pressing sheet 4232, the pressing sheet 4232 is pressed into the mounting cover 4231, the pressing sheet 4232 pushes the lifting block 4233 to move along the threaded column 4235 in a pressing process, the connection mode of the lifting block 4233 and the pressing sheet 4232 can refer to a screw rod and a sliding sleeve, the threaded column 4235 and the mounting cover 4231 can only rotate and cannot deviate from the position, then the movable lifting block 4233 presses the separation spring 4238 of a release section, the deceleration resistance of the lifting block 4233 is larger, and then the connected vehicle cannot easily collide with a front vehicle in a sliding running process.
As shown in fig. 3, 4, 5 and 6, the limiting and guiding mechanism 43 includes a blocking cover 431 connected to the warning deceleration channel 411, the blocking cover 431 is connected to a blocking rod 432 through a rotating shaft, one end of the blocking rod 432 near the blocking cover 431 is connected to a stretching bar 433, a rotating tooth column 434 for winding the stretching bar 433 is penetratingly disposed at the bottom of the blocking cover 431, one end of the rotating tooth column 434 near the blocking cover 431 is connected to the stretching bar 433, and the other end of the rotating tooth column 434 is connected to the driving pushing tooth column 428.
In order to realize the condition of guiding the vehicle to slide, when the vehicle is implemented, once the driving pushing toothed column 428 is pushed by the pushing block 425, the direct engaging pushing rotary toothed column 434 rotates, taking fig. 3 as an example, when the first driving pushing toothed column 428 is rotated with the engaging pushing rotary toothed column 434, the rotating rotary toothed column 434 winds the stretching strip 433, so that one end of the blocking rod 432 is pulled to rotate around the rotating shaft, and the process is repeated until the blocking rod 432 is turned to the maximum extent, so that the operation of guiding the vehicle to move can be realized.
In this embodiment, once the first driving pushing tooth column 428 is no longer pushed by the deceleration strip 422, that is, after the vehicle is far away from the deceleration strip 422, the resetting column 429 at the first driving pushing tooth column 428 is activated to reset the first driving pushing tooth column 428, but due to the existence of the deceleration strip 426, the resetting time of the first driving pushing tooth column 428 is slow, and in the process, the second driving pushing tooth column 428 is pressed again, and the cycle is repeated until the three driving pushing tooth columns 428 are all pushed, and after the vehicle is discharged, the resetting operation is performed, that is, the three driving pushing tooth columns 428 are all pulled and reset by the components in the resetting column 429, that is, the resetting column 4291 and the resetting spring 4293, and in order to make the above three-stage meshing pushing operation smooth, the lengths of the driving pushing tooth columns 428 are set to be linearly decreased from the side close to the stop cover 431 to the side far from the stop cover 431, therefore, the situation that a certain driving pushing tooth column 428 cannot be meshed with the rotating tooth column 434 is avoided, and a pipeline which is convenient for the driving pushing tooth column 428 to pass through is arranged on the warning deceleration channel 411.
An implementation method adopting an intelligent interchange system comprises the following steps:
