[0036] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of the specific implementation, structure, features and effects of a water-saving sprinkler device for greening proposed by the present invention in combination with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures or characteristics in one or more embodiments may be combined in any suitable form.

[0037] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0038] This embodiment provides a water-saving sprinkler device for greening, including a sprinkler device body, and a height adjustment analysis module is also installed on the sprinkler device body. The height adjustment analysis module is used to perform feature analysis and height adjustment effect evaluation based on the collected wind speed data and wind direction data at different times to determine the optimal height adjustment amount. Therefore, the height adjustment analysis module includes a data acquisition module, a computing chip and a sprinkler height control module. Among them, the data acquisition module is connected to the computing chip, which is used for data processing and machine control. The chip type is FPGA, which receives information from the data acquisition module and sends control instructions to the sprinkler height control module.

[0039] The specific scheme of a water-saving sprinkler irrigation device for greening provided by the present invention is described in detail below with reference to the accompanying drawings.

[0040] See also Figure 1, which shows a schematic structural diagram of a water-saving sprinkler device for greening provided by an embodiment of the present invention, the sprinkler device includes a wind speed and direction sensor 1; a sprinkler nozzle water outlet 2; a water inlet pipe 3; a primary device wall 4; a secondary device wall 5; a tertiary device wall 6; a nozzle head 7; the nozzle head 7 is connected to the tertiary device wall 6, and the tertiary device wall is raised and lowered to cause different height changes of the sprinkler device.

[0041] The data acquisition module of this embodiment includes a wind speed and direction sensor 1; the wind speed and direction sensor is used to measure the air flow velocity and direction around the sprinkler irrigation device, and can help determine the optimal sprinkler irrigation height by measuring the wind speed and direction.

[0042] In this embodiment, the sprinkler height control module includes a three-level device wall 6, which is used to receive the control command of the computing chip and adjust the height of the sprinkler. When the sprinkler height control module receives the control command, it drives the support bottom rod to adjust the lifting height of the three-level device wall 6 to the optimal height. Figure 2 , which shows a schematic diagram of the state of the sprinkler irrigation device after height adjustment; after adjusting to the optimal height, the nozzle head 7 is driven to perform sprinkler irrigation operations.

[0043] The data acquisition module is connected to the signal input end of the computing chip, and the signal output end of the computing chip is connected to the sprinkler height control module. The sprinkler height control module is used to adjust the height of the sprinkler device; the data acquisition module is used to collect wind speed data and wind direction data at different times and transmit them to the computing chip.

[0044] In this embodiment, a number of time moments may be pre-allocated to collect wind speed and wind direction data of the wind direction and wind speed sensors at corresponding time moments. As a specific example, it may be preset that every 5 seconds is a time moment, and the data is collected for a total of 1 hour.

[0045] For further information, see Figure 3 , which shows a schematic diagram of the data processing flow of wind direction and wind data by a computing chip in a water-saving sprinkler device for greening of the present invention, including the following steps:

[0046] Step S001: Analyze the wind direction change of the sprinkler irrigation area where the same sprinkler irrigation device is located according to the wind direction data to obtain the complexity of the wind direction change of each sprinkler irrigation device.

[0047] It should be noted that for any sprinkler device, since it is fixed in one place, it will irrigate the green plants in the area around the sprinkler device when it is working; in the water mist sprayed from the nozzle of the sprinkler device, the water droplets are small in volume, resulting in a smaller mass of the water droplets, so they are more easily affected by the airflow and wind direction, causing the original diffusion direction of the water mist to change; therefore, the wind direction changes in the sprinkler area where the same sprinkler device is located can be analyzed based on the wind direction data to obtain the complexity of the wind direction changes for each sprinkler device. Among them, if the complexity of the wind direction change is greater, it means that the flow of people in the surrounding space of the sprinkler device is more active, the change of the airflow in the space is more obvious, and the wind direction changes in the surrounding space of the sprinkler device are more complex. Please refer to Figure 4 , which shows a schematic diagram of the sprinkler irrigation device, wherein the dotted area is the sprinkler diffusion trajectory of the water mist in the air.

[0048] Preferably, in some implementations of the embodiments of the present invention, the method for obtaining the complexity of wind direction change is: for any sprinkler irrigation device, obtain the overall environmental wind direction value of the sprinkler irrigation device; and obtain the complexity of wind direction change of the sprinkler irrigation device according to the wind direction difference between each wind direction data of the sprinkler irrigation device and the overall environmental wind direction value. The specific process is:

[0049] The average of the wind direction data of the sprinkler at all times is taken as the overall environmental wind direction value of the sprinkler. As an example, the complexity of wind direction change can be calculated by the following formula:

[0050]

[0051] In the formula, A i represents the complexity of wind direction change of the i-th sprinkler; T represents the number of all moments; w i,t represents the wind direction data of the i-th sprinkler at the t-th moment; W i represents the overall environmental wind direction value of the i-th sprinkler device; norm[] represents the normalization function; Indicates the difference in wind direction.

[0052] It should be noted that if the complexity of wind direction changes is greater, it means that the flow of people in the space around the sprinkler irrigation device is more active, the change of airflow in the space is more obvious, and the wind direction changes in the space around the sprinkler irrigation device are more complex.

[0053] So far, the complexity of wind direction change of each sprinkler device is obtained through the above method.

[0054] Step S002: Analyze the continuous change of wind speed intensity in the sprinkler irrigation area where the same sprinkler irrigation device is located based on the wind speed data to obtain the wind speed change continuity of each sprinkler irrigation device; analyze the overall wind speed intensity of the sprinkler irrigation area where the same sprinkler irrigation device is located based on the wind speed change continuity to obtain the wind speed intensity stability of each sprinkler irrigation device.

[0055] It should be noted that, under normal circumstances, the space area around the sprinkler device is ventilated with the outside world, so the airflow in the surrounding space is not completely static, and the wind speed changes more or less over time; and when the wind speed changes more continuously, it means that the degree of interference with the airflow in the space around the sprinkler is lower; therefore, the continuous change of wind speed intensity in the sprinkler area of ​​the same sprinkler device can be analyzed based on the wind speed data to obtain the continuity of wind speed change for each sprinkler device.

[0056] It should be further explained that, during the period when the wind speed changes are relatively continuous, if the overall wind speed intensity in the space surrounding the sprinkler irrigation device is greater, it means that the circulation intensity of the airflow in the space surrounding the sprinkler irrigation device can be sustained at a higher intensity, reflecting that the airflow intensity in the space surrounding the sprinkler irrigation device is more stable; therefore, based on the continuity of wind speed changes, the overall wind speed intensity of the sprinkler irrigation area of ​​the same sprinkler irrigation device can be analyzed to obtain the wind speed intensity stability of each sprinkler irrigation device.

[0057] Preferably, in some implementations of the embodiments of the present invention, the method for obtaining the wind speed change continuity is: for any sprinkler irrigation device, analyzing the difference in wind speed data of the sprinkler irrigation device between adjacent moments to obtain the continuous wind speed difference value of the sprinkler irrigation device; and obtaining the wind speed change continuity of the sprinkler irrigation device according to the continuous wind speed difference value. The specific process is:

[0058] The absolute value of the difference between the wind speed data of the sprinkler irrigation device at adjacent moments is taken as the local adjacent wind speed difference; the mean value of all local adjacent wind speed differences is taken as the continuous wind speed difference value of the sprinkler irrigation device.

[0059] Furthermore, the inversely proportional normalized value of the continuous wind speed difference value is used as the wind speed change continuity of the sprinkler irrigation device.

[0060] It should be noted that if the wind speed change continuity is greater, it means that the wind speed change is more continuous, reflecting that the degree of interference with the air flow in the space around the sprinkler irrigation is lower.

[0061] It is particularly noted that the present embodiment adopts the exp(-x) model to present the inverse proportional relationship and normalization processing, x is the input of the model, and the implementer can select the inverse proportional function and the normalization function according to the actual situation.

[0062] Preferably, in some implementations of the embodiments of the present invention, the method for obtaining the wind speed intensity stability is: for any sprinkler irrigation device, obtain the regional wind speed intensity mean of the sprinkler irrigation device; obtain the wind speed intensity stability of the sprinkler irrigation device according to the wind speed change continuity and the regional wind speed intensity mean; the wind speed intensity stability is positively correlated with the wind speed change continuity and is positively correlated with the regional wind speed intensity mean. The specific process is:

[0063] The average of the wind speed data of the sprinkler at all times is taken as the regional wind speed intensity average of the sprinkler. As an example, the wind speed intensity stability can be calculated by the following formula:

[0064]

[0065] In the formula, B i represents the wind speed intensity stability of the i-th sprinkler device; represents the mean wind speed intensity of the i-th sprinkler; f i It represents the wind speed variation coherence of the i-th sprinkler device; norm() represents the normalization function.

[0066] It should be noted that if the wind speed intensity stability is greater, it means that the overall wind speed intensity in the space surrounding the sprinkler irrigation device is greater, and the circulation intensity of the airflow in the space surrounding the sprinkler irrigation device can be sustained at a higher intensity, reflecting that the airflow intensity in the space surrounding the sprinkler irrigation device is more stable.

[0067] So far, the wind speed intensity stability of each sprinkler device is obtained through the above method.

[0068] Step S003: combining the complexity of wind direction changes and the stability of wind speed intensity, analyzing the influence of airflow on water evaporation in the sprinkler irrigation area where the same sprinkler irrigation device is located, and obtaining the airflow evaporation degree of each sprinkler irrigation device.

[0069] It should be noted that for any sprinkler irrigation device, if the wind direction changes in the space around the sprinkler irrigation device more frequently and complexly, and the wind speed intensity is more stable at a higher intensity, it means that the moisture in the soil of the green plants around the sprinkler irrigation device is driven to a greater extent by the airflow, and the activity of the water molecules in the soil of the green plants is more intense, which reflects that the evaporation efficiency of the moisture in the soil of the green plants around the sprinkler irrigation device is faster.

[0070] Preferably, in some implementations of the embodiments of the present invention, the method for obtaining the airflow evaporation degree is: according to the complexity of wind direction changes and the stability of wind speed intensity of the sprinkler irrigation device, the airflow evaporation degree of the sprinkler irrigation device is obtained; the airflow evaporation degree is positively correlated with the complexity of wind direction changes and the stability of wind speed intensity. The specific process is:

[0071] As an example, the degree of airflow evaporation can be calculated by the following formula:

[0072] C i =A i ×B i

[0073] In the formula, C i A represents the degree of airflow evaporation of the i-th sprinkler device; i represents the complexity of wind direction change of the i-th sprinkler; B i Represents the wind speed intensity stability of the i-th sprinkler device.

[0074] It should be noted that if the degree of air flow evaporation is greater, it means that the degree to which the moisture in the soil of the green plants around the sprinkler irrigation device is driven by the air flow is greater, the activity of the water molecules in the soil of the green plants is more intense, which reflects that the evaporation efficiency of the moisture in the soil of the green plants around the sprinkler irrigation device is faster.

[0075] So far, the airflow evaporation degree of each sprinkler irrigation device is obtained through the above method.

[0076] Step S004: adaptively acquiring the height adjustment amount of each sprinkler device according to the degree of airflow evaporation, and outputting a control instruction according to the height adjustment amount, so as to control the height of the sprinkler device to be adjusted to an optimal height.

[0077] As an example, the height adjustment can be calculated using the following formula:

[0078] H i =C i ×h i

[0079] In the formula, H i represents the height adjustment of the i-th sprinkler device; C i Indicates the degree of airflow evaporation of the i-th sprinkler device; h i Represents the maximum height that the i-th sprinkler can reach.

[0080] It should be noted that if the height adjustment amount is larger, it means that the water evaporation efficiency of the green plants around the sprinkler device is relatively faster, and it is more necessary to lower the height of the sprinkler device for concentrated sprinkler irrigation of the green plants, so that the water mist sprayed by the sprinkler device can fall more effectively on the soil of the green plants and be absorbed by the green plants, thereby reducing the amount of water lost due to evaporation before the water mist is absorbed by the green plants.

[0081] Furthermore, the height of the i-th sprinkler irrigation device is initially adjusted to the maximum height, the height adjustment amount of the i-th sprinkler irrigation device is output to the computing chip, and the height adjustment amount is used as a control instruction to drive the supporting bottom rod to lower the third-level device wall 6 to the same value as the height adjustment amount to the optimal height.

[0082] At this point, this embodiment is completed.

[0083] The embodiments described above are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
