The inner wall body is first atomized glass, and the outer wall body is second atomized glass. When the intelligent retaining wall is installed, the inner wall body is close to the inner side of the road, and the outer wall body is close to the outer side of the road. The thickness of the first atomized glass and the second atomized glass is more than 8mm, so that flying stones brought up when the automobile passes can be resisted. The wall 3 is 2 m high and 3 m wide.
The intelligent retaining wall further comprises a controller 6, wherein the controller is electrically connected with the first atomizing glass and the second atomizing glass and controls the power on and power off of the first atomizing glass and the second atomizing glass. The atomizing area of the first atomized glass covers the entire first atomized glass. The atomizing area is transparent when energized and is atomized in white when deenergized. The atomizing area of the second atomizing glass covers only a portion of the second atomizing glass. The atomizing area can be made into a warning word, such as 'meeting in front, danger', and the like, for realizing a warning function. The warning character occupies 70% of the height of the whole wall. The atomized character is made by adopting an atomization carving process, so that atomized liquid crystal particles are filled in the character after the character is carved on the glass, the atomized character is completely transparent when the power is on, and the atomized white warning character is displayed when the power is off.
The controller 6 controls the energization and the de-energization of the first and second glass atomizers according to a first preset condition, for example, a preset clock condition.

The camera can identify the distance between different vehicles and the camera and the speed of the vehicles, and the camera device 2 transmits identification data to the controller 6 in a wired or wireless communication mode. The controller 6 controls the energization and the de-energization of the first and second atomizing glasses according to whether or not the data transmitted by the image pickup device 2 satisfies the second preset condition.
The second preset condition is prioritized over the first preset condition.
Example 2
The intelligent retaining wall of embodiment 2 further comprises a photosensitive sensor 7 based on embodiment 1, and the controller 6 controls the power on and off of the first and second atomizing glasses according to a first preset condition, for example, a preset threshold value of the photosensitive sensor 7.
Example 3

The first atomization area and the second atomization area are made into different types, and the first atomization area is the same as embodiment 1 and used for realizing the first warning function. The second atomization area is different from the first atomization area in word, such as information including telephone numbers of road rescue, and is used for realizing a second warning function. The first atomization area and the second atomization area are transparent when energized, and are atomized in white when deenergized, and are respectively controlled by the controller 6 according to the second preset condition or the third preset condition.
Example 4

the preset threshold value in this embodiment is 30000lux. When the photosensitive sensor 7 senses that the illuminance is greater than the preset threshold value, the controller 6 controls the first atomized glass to be powered off and the second atomized glass to be powered off, so that sunlight cannot be emitted into the vehicle cab from the side surface level when the vehicle turns due to the fact that the first atomized glass is in a white fog state. When the photosensitive sensor 7 senses that the illuminance is smaller than the preset threshold value, the controller 6 controls the first atomized glass to be electrified, and the second atomized glass is electrified. At this time, both the first and second glass atomizes are transparent.
Meanwhile, the method for controlling the first and second atomized glasses by the controller 6 according to whether the data transmitted by the image pickup device 2 satisfies the second preset condition is as follows:
the second preset condition is that vehicles are arranged on two sides of the mountain highway, for example, when the camera device 2 judges that vehicles (a first vehicle 4 and a second vehicle 5) come and go at the same time on two sides of the highway, any vehicle is smaller than a preset distance from the camera device 2, for example, within ten meters, and any vehicle hour speed is higher than a preset speed, for example, 10 km/h, the controller controls the first atomized glass to be electrified, the first atomized glass to be transparent, the controller controls the second atomized glass to be powered off, and an atomization warning word of a meeting prompt appears in an atomization area of the second atomized glass, for example, the situation that vehicles meet in front and danger exists.
Wherein control is prioritized with whether or not the data transmitted according to the image pickup device 2 satisfies the second preset condition.
Example 6
