Description

Technical Field

[0002] Railway subgrades in sandy areas, especially exposed subgrades without protective conditions, are exposed to the action of sandstorms for a long time, and are eroded and abraded by sandstorms, causing the subgrades to suffer different degrees of erosion, and in severe cases, sand accumulation on the roadbed and subgrade damage. For this situation, the current method is to protect the subgrade by planting green plants beside the railway subgrade. In order to allow green plants to survive for a long time, it is necessary to provide green plants with a good living environment and water resources. Therefore, it is necessary to build water pipes on both sides of the railway subgrade to ensure the natural environment required for the survival of green plants. However, for sandy areas, their dry climate is obviously not suitable for the natural growth of green plants. Even if sufficient water resources are provided, it is necessary to manually maintain the green plants regularly, such as by pruning branches and leaves so that the green plants can maintain the necessary nutrients in such a harsh environment. For some extreme weather, it is obviously not realistic to manually maintain green plants, and manual maintenance requires workers to have a lot of rich plant knowledge to achieve the effect of pruning green plants according to the environment so that the green plants can resist the sandstorms well. Obviously, a relatively high threshold of manpower and material resources is currently required to complete the maintenance of railway roadbed plants in desert areas. Summary of the invention

[0050] like Figure 1-5 As shown, the present invention provides a device for planting plants on railway roadbed in desert areas, comprising a support rod 1 in the vertical direction, such as Figure 1-4 As shown, the support rod 1 is provided with an environmental sensor 11, a first annular frame 12, a second annular frame 2 and a planting box 4 with an opening upward in sequence from top to bottom, and the support rod 1 is also provided with a processor 7 and a power supply 9;

[0051] The first annular frame 12 is connected to the support rod 1 through a first lifter 10, and a camera 13 is connected to the inner side of the first annular frame 12 through a first sliding connection member;

[0052] The second annular frame 2 is connected to the support rod 1 via a second lifter 8, and the inner side of the second annular frame 2 is connected to a trimming mechanism via a second sliding connection;

[0053] The planting boxes 4 are used to place soil for planting plants, and each of the planting boxes 4 is connected by a water distribution pipe 17;

[0054] The processor 7 is respectively connected to the environmental sensor 11, the camera 13, the first driver for driving the first sliding connection, the trimming mechanism, the second driver for driving the second sliding connection, the first lifter 10 and the second lifter 8 by signals;

[0055] The power supply 9 is electrically connected to the processor 7, the camera 13, the first driver, the trimming mechanism, the second driver, the first lifter 10 and the second lifter 8 respectively;

[0056] The processor 7 is used to determine the style of pruning the plants according to the data collected by the environmental sensor 11 and the camera 13, and control the pruning mechanism to prune the plants.

[0057] The above is the structural part of the plant cultivation device provided by the present invention, which provides the original data of the current plant state model under the current state, and provides the structural support for pruning the plants according to the judgment results.

[0058] The core of the present invention lies in the operation of the processor 7, and the operation process of the processor 7 includes the following steps:

[0059] S1: Control the first lifter 10 to perform lifting motion at a set time point, and at the same time control the first driver to drive the first sliding connection member to make the camera 13 rotate inside the first annular frame 12, and receive data transmitted by the camera 13;

[0060] S2: constructing a plant virtual model according to the data transmitted by the camera 13 to obtain a current plant state model;

[0061] S3: receiving environmental data monitored by the environmental sensor 11, and searching for a corresponding ideal plant model in a database according to the environmental data;

[0062] S4: obtaining a pruning plan according to the difference between the current plant state model and the ideal plant model;

[0063] S5: According to the pruning plan, the second lifter 8 is controlled to perform lifting movement, and at the same time, the second driver is controlled to drive the second sliding connection member so that the pruning mechanism rotates inside the second annular frame 2, and the pruning mechanism is controlled to complete the pruning of the plants;

[0064] The pruning plan includes pruning positions and corresponding pruning routes.

[0065] Among them, in step S1, the present invention performs the operation of the present invention once at a set time. Therefore, the above steps S1-S5 are executed once at the set time point to complete the plant pruning work once. According to the steps described in step S1, the movement trajectory of the camera 13 is spiral up and down, so that the shape data of the plant can be comprehensively collected. Step S2 splices and processes the pictures taken from various directions to obtain the current plant state model. Step 2 can be achieved using existing technology. Step S3 is to obtain an ideal plant model suitable for the current environment based on the environmental conditions, and then step S4 is compared. Step S5 is to intelligently prune the plants based on the comparison results, so that the pruned plants fit the shape of the ideal plant model.

[0066] In step S3 of the present invention, when searching for an ideal plant model, a database is required. The database may be stored locally in the processor 7 or obtained from the cloud. Figure 5 As shown, the cloud platform is a huge database for storing and updating environmental data and its corresponding ideal plant model in real time. The main control unit is used to correct and adjust the data on the cloud platform. The processors of each plant cultivation device are connected to the cloud platform through a communication connection device, and the communication connection device can be wireless, such as GPRS.

[0067] Furthermore, in order to further refine the operation mode of the processor 7 and improve the efficiency of the operation, the present invention technically limits step S4. In step S4, the pruning plan is obtained according to the difference between the current plant state model and the ideal plant model, including:

[0068] 1. Construct a three-dimensional coordinate system, and enter the current plant state model and the ideal plant model into the same constructed three-dimensional coordinate system respectively;

[0069] 2. Establish a label for each point in the three-dimensional coordinate system, where the label is a set of color values;

[0070] 3. Setting a first color value for each point of the current plant state model in the three-dimensional coordinate system, and filling the first color value in the label of the corresponding point, and setting a second color value for each point of the ideal plant model in the three-dimensional coordinate system, and filling the second color value in the label of the corresponding point;

[0071] 4. Move the current plant state model and the ideal plant model respectively so that the number of labels containing both the first color value and the second color value in the three-dimensional coordinate system is maximized;

[0072] 5. Extract the points where the labels containing only the first color value are located in the three-dimensional coordinate system to obtain the difference;

[0073] 6. Obtain a pruning plan based on the differences.

[0074] The above steps 1-6 are to quickly locate and advance the difference parts through the three-dimensional coordinate system, and the difference parts are also represented in three dimensions. The present invention establishes labels, each label corresponds to the color value of each point, and the overlapping part has multiple color values, so that the overlapping part can be quickly located, and then the part of the current plant that needs to be pruned can be distinguished. A cumbersome comparison process is simplified, and only the content of the label of each point needs to be compared.

[0075] For the part of the pruning plan, the present invention makes the following limitation: the difference part is pruned away, that is, the pruning plan is obtained according to the difference, and the pruning plan includes:

[0076] <1> According to each point of the difference in the three-dimensional coordinates, the three-dimensional coordinates are divided into a plurality of trimming areas according to the trimming range of the trimming mechanism;

[0077] <2> Determine the pruning position in the pruning plan according to each of the pruning areas;

[0078] <3> The corresponding trimming lines are determined according to the positions of the various points in the trimming regions.

[0079] In the present invention, the pruning mechanism can rotate around the three-dimensional area of ​​the plant due to the action of the second lifter 8 and the second ring frame 2. This is the pruning range of the pruning mechanism, and the area is divided into multiple pruning areas. Each pruning area is responsible for pruning a place. Each pruning area has a representative coordinate, which is the pruning position. The place where the pruning knife 3 prunes is the pruning line. In step <3> In the figure, each point in the pruning area forms a three-dimensional image of the plant that needs to be pruned.

[0080] The step of determining the corresponding trimming line according to the position of each point in each trimming area includes:

[0081] -1-According to each point in each trimmed area, obtain the color area in each trimmed area;

[0082] -2- Extract the boundaries of each color area and determine the trimming line based on the boundaries.

[0083] In the above process, the three-dimensional points are rendered, and the edge boundaries of the image are more easily distinguished by color, so that trimming along the boundaries can be performed even if the lines are trimmed.

[0084] Regarding the structure of the present invention, the trimming mechanism is further defined, and the trimming mechanism includes a position converter 14 and a trimming knife 3;

[0085] The position converter 14 is connected to the second connecting member, and the trimming knife 3 is connected to the output end of the position converter 14;

[0086] The processor 7 is respectively connected to the position converter 14 and the trimming knife 3 by signals, and the power supply 9 is respectively connected to the position converter 14 and the trimming knife 3 by electrical signals;

[0087] The processor 7 controls the position converter 14 to change the position and posture of the trimming knife 3, and controls the trimming knife 3 to trim.

[0088] Among them, the position converter 14 is used to adjust the position and angle of the pruning knife 3, so as to complete the pruning. When pruning, the position converter 14 is kept away from the above-mentioned three-dimensional points as much as possible, otherwise it is necessary to re-perform three-dimensional stereo modeling to obtain the above-mentioned pruning route.

[0089] The pruning knife 3 can adopt electrically controlled scissors to prune the branches and leaves of plants.

[0090] The position converter 14 can be set up in the form of an electric telescopic link and an electric universal shaft, so that the position can be adjusted like a human arm. Generally, it is best to have two electric telescopic links and one electric universal shaft, which is equivalent to a robotic arm. At that time, the present invention can also use a robotic arm to replace the position converter 14 part of the trimming mechanism.

[0091] Here is an embodiment, the position converter 14 includes a first cardan shaft connected to the second connecting member, the first cardan shaft is connected to one end of the electric telescopic rod, and the other end of the electric telescopic rod is connected to the pruning knife 3 through a second cardan shaft;

[0092] The processor 7 is respectively connected to the first cardan shaft, the second cardan shaft and the electric telescopic rod by signal, and the power supply 9 is respectively connected to the first cardan shaft, the second cardan shaft and the electric telescopic rod by electrical signal.

[0093] Among them, the electric telescopic rod can adjust the length, the universal shaft can adjust the angle, the first universal shaft adjusts the angle between the two electric telescopic rods, and the second universal shaft adjusts the angle between the electric telescopic rod and the pruning knife 3. They are all controlled by the processor 7, and the processor 7 is controlled according to the pruning line.

[0094] In addition, in the present invention, in order to make the circulation of water resources smoother, each planting box 4 has enough water to ensure that the plants maintain sufficient water resources and nutrition in the desert, and ensure that the plants in the planting box 4 can grow well. In the present invention, the lower end of the support rod 1 is a hollow structure, and the bottom of the lower end of the support rod 1 is respectively provided with two opposite water guide holes 6 and a water injection hole 5; the water guide hole 6 is used to pass through the water guide pipe 15, and the water injection hole is used to pass through the water injection pipe 16, the water guide pipe 15 is connected to the water injection pipe 16, and the water injection pipe 16 is connected to the planting box 4.

[0095] In the above, the present invention distributes water resources evenly to each planting box 4 of the plant cultivation device through the water pipe 15, thereby ensuring that the soil in each planting box 4 is moist and suitable for plant growth. In the present invention, a heat preservation and moisture-keeping film can be plated on the surface of the planting box 4 to properly keep the inside of the planting box 4 warm and moist, and prevent extreme weather in the desert from interfering with the temperature and humidity of the inner wall of the planting box 4.

[0096] The present invention provides a device for planting and surviving plants on railway roadbed in desert areas. The seedlings are pruned, and the main purpose is to reduce the dissipation of water and ensure the balance of tree vigor to ensure the survival of trees. The amount of pruning varies according to the requirements of different tree species. Shrubs are not pruned much, and only dead and diseased branches and injured branches are pruned. For larger trees, especially those with strong growth potential and easy to extract new branches, strong pruning can be carried out, and more than 1 / 2 of the crown can be pruned. This can reduce the burden on the root system, maintain the water balance in the tree body, and also make the trees stable after planting and not sway in the wind.

[0097] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention still falls within the protection scope of the technical solution of the present invention.
