Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

The present inventors have proposed a solution to the problems in the background art described above. One embodiment of the present invention provides a water-saving irrigation processing method in combination with an internet of things module, which can be executed in a computing device.

When the spray irrigation is selected, the staff of the invention combines the local actual situation, selects a proper irrigation mode according to the intention of local farmers, and the main water-saving irrigation mode is characterized in that the following table 1 is adopted:

TABLE 1

In the practical application scene, the invention can be used according to the characteristics of various irrigation modes, the farmers' own wishes and plant crops, the fields adopt semi-fixed sprinkling irrigation and buried telescopic sprinkling irrigation, the vegetables adopt drip irrigation, the fruit trees adopt small pipe outflow and micro sprinkling irrigation, the medicinal materials adopt inverted micro sprinkling and the flowers adopt ground inserting micro sprinkling.

In addition, the invention can have a water and fertilizer integrated treatment mode, namely according to different irrigation modes, the types of planted crops and the wishes of users, the water and fertilizer integrated system is selected as follows:

(1) The motor-pumped well head adopts a pump injection type plunger pump and a fertilizing tank.

(2) The field small head part adopts a Venturi fertilizer applicator and a fertilizer tank.

The necessity of water and fertilizer integration adopted by field sprinkling irrigation is as follows, that the traditional fertilizer has serious fertilizer absorption rate, serious fertilizer waste, easy soil pollution, no environmental protection requirement, more manual consumption and no requirement of modern agricultural production. In the sprinkling irrigation fertilization, the fertilizer is easier to be absorbed by crops, the utilization rate of the fertilizer is improved, the dynamic requirement of the crops on the fertilizer is easily met, and the situation of excessive early-stage fertilizer and lack of later-stage fertilizer does not occur. After the sprinkling irrigation system is sprayed, the whole system can be leached, so that the foliar retention fertilizer can be reduced, and the blocking problem of the irrigation system is reduced. Meanwhile, the labor consumption can be reduced, and the production efficiency is improved.

Fig. 1 illustrates a flow chart of a method of water-saving irrigation processing in combination with an internet of things module, the method being suitable for execution in a computing device, according to one embodiment of the invention.

As shown in fig. 1, the water-saving irrigation processing method combined with the internet of things module according to the present embodiment starts with step S102, and in step S102, the method includes the following steps:

Attribute areas corresponding to different plant attributes are determined in a planting field based on a field floor view corresponding to the planting field, wherein the plant attributes include potting attributes and field planting attributes.

For example, in the present embodiment, since a seed of a certain plant may be planted in soil in one planting field and may be cultivated into a flowerpot after the seed is germinated, a plant having a potting property and a plant having a field planting property may be simultaneously planted in one planting field.

Because the irrigation modes adapted to the plants with different plant attributes are different, the server can acquire the field view corresponding to the planting field, so that the attribute areas corresponding to the different plant attributes are determined in the planting field according to the field view, and corresponding irrigation allocation is convenient to follow-up.

Further, the above-mentioned "determining the attribute areas corresponding to different plant attributes in the planting field based on the field view corresponding to the planting field", wherein the plant attributes include potting attributes and field planting attributes ", further includes the following steps:

For example, in this embodiment, the server may first obtain a field view of the planting field, and perform image recognition on the field view according to the retrieved plant attribute recognition policy, so as to determine, according to the recognition result, each plant located in the planting field and each plant attribute corresponding to each plant, where the plant attribute includes a potting attribute and a field attribute. Plants planted in the flower pot, i.e., have potting properties, and plants planted in the soil, i.e., have field properties.

Then, the server determines the outline of each plant in the field view, that is, the outline of each plant, because some plants are closely spaced, that is, have association relationship, in order to facilitate the unified irrigation of the subsequent plants having the same plant attribute and association relationship, the server divides the various plants corresponding to the same plant attribute and having association relationship into the same plant division group, and then combines the outlines of the plants corresponding to the same plant division group, so as to obtain the division outlines corresponding to the plant division groups. At this time, the server determines each divided area included in each divided contour as an attribute area corresponding to a different plant attribute.

Further, the above-mentioned "obtaining a field view corresponding to a planting field, performing image recognition on the field view based on a retrieved plant attribute recognition policy, and determining various plants located in the planting field and various plant attributes corresponding to the various plants based on a recognition result" further includes the following steps:

For example, in this embodiment, when the current time reaches the preset acquisition time, the server triggers the image acquisition unit to acquire an image of the planting field, so as to obtain a field view corresponding to the planting field. Then, the server performs pixel recognition on the field map to obtain respective field pixel values corresponding to respective field pixel points constituting the planting field.

And then, the server can call out a preset first pixel value corresponding to the green leaf and a preset second pixel value corresponding to the soil, and respectively calculate the difference value between each field pixel value and the preset first pixel value and the preset second pixel value, so as to obtain each first difference value and each second difference value.

Then, the server may call a preset difference interval, and when the first difference or the second difference is located in the preset difference interval, it indicates that the field pixel value corresponding to the first difference is close to the preset first pixel value or the field pixel value corresponding to the second difference is close to the preset second pixel value. Therefore, the server divides each field pixel point corresponding to each first difference value located in the preset difference value interval into a first pixel group and each field pixel point corresponding to each second difference value located in the preset difference value interval into a second pixel group.

At this time, the server connects the field pixel points having the connection relationship in the first pixel group and the second pixel group, so as to obtain each first pixel region corresponding to the first pixel group and each second pixel region corresponding to the second pixel group.

Since there is a possibility that the plant having the field planting property is not moved into the flowerpot immediately after the emergence of the plant, that is, there may be a plant having the field planting property in the first pixel group. Therefore, the server further obtains the number of pixels in each first pixel area, so as to obtain the number of pixels in each first pixel area, and determines the number of pixels with the largest corresponding number as the largest number and the number of pixels with the smallest corresponding number as the smallest number. And then carrying out average value calculation on the maximum number and the minimum number, and comparing the obtained number average value with the number of each pixel.

When any one of the pixel numbers is less than or equal to the number average value, it means that the first pixel area corresponding to the pixel number is smaller, and possibly a plant having a ground planting property that is not transferred into the flowerpot, so the server determines the first pixel area corresponding to the pixel number less than or equal to the number average value as the updated second pixel area.

After the updating of each first pixel area and each second pixel area is completed, the server respectively determines each first pixel area as each plant corresponding to the potting attribute and each second pixel area as each plant corresponding to the corresponding potting attribute.

Further, the above-mentioned "determining, in the field view, each plant outline corresponding to each of the various plants and dividing each plant corresponding to the same plant attribute and having an association relationship into the same plant division group" further includes the steps of:

For example, in this embodiment, in order to determine the plant outline of each plant, the server determines each field pixel point located at the edge as each edge pixel group corresponding to each pixel region in each pixel region corresponding to each plant, and connects, that is, connects, pixels, each field pixel point located at an adjacent position in the same edge pixel group, thereby obtaining each plant outline corresponding to each plant.

Then, the server determines each plant outline corresponding to the potting attribute as a potting outline group and each plant outline corresponding to the planting attribute as a ground planting outline group. And obtaining the distance between every two plant outlines in the potted outline group, thereby obtaining the distance between every two potted outlines. Then, the server will call the preset distance, when the outline distance of potting is smaller than or equal to the preset distance, it means that the outline distance of potting is smaller, that is, the outline distance of two plants corresponding to the outline distance of potting is closer, so the server will divide various plants with the outline distance of potting less than or equal to the preset distance into the same plant division group.

Then, the server obtains the distance between every two plant outlines in the ground planting outline group, so as to obtain the distance between every two plant outlines, and then divides various plant plants with the corresponding ground planting outline distance smaller than or equal to the preset distance into the same plant dividing group.

According to the method, various planting plants corresponding to the same plant attribute and having an association relationship can be divided into the same plant division groups through calculating the outline distance of each pot plant and the outline distance of each field planting, so that unified irrigation allocation can be conveniently carried out on the plants in the follow-up process, and a certain irrigation effect can be improved.

Further, the above-mentioned "combining the profiles of the plants corresponding to the plants in the same plant division group to obtain the division profiles corresponding to the plant division groups", further includes the following steps:

For example, in this embodiment, the server obtains each distance point and each distance direction of each plant contour corresponding to each contour distance in the same plant dividing group, and as shown in fig. 2, line segment a is the contour distance, A1 and A2 are both distance points, and the indication arrow e indicates the distance direction.

Then, the server forms each extending line segment with a preset line segment length in each plant outline along the distance direction, and the extending line segments shown in fig. 2 are c1 and c2 respectively. Then, the server generates intersecting line segments perpendicular to the distance direction and intersecting the plant contour in the corresponding plant contour, with the line segment end point of each extending line segment as a starting point, and the intersecting line segments are C1D1 and C2D2 as shown in fig. 2. And determining a first intersecting point and a second intersecting point which intersect the plant outline according to the intersecting line segment, wherein the first intersecting point is C1 and C2 respectively, and the second intersecting point is D1 and D2 respectively as shown in FIG. 2.

Then, the server connects the plant profiles at adjacent positions by the corresponding first intersecting points and the corresponding second intersecting points, so as to obtain connection profiles for connecting the plant profiles, wherein the connection profiles are b1 and b2 as shown in fig. 2. And combining the profiles of the various plants according to the connecting profiles, so as to obtain the dividing profiles corresponding to the plant dividing profiles.

According to the method and the device, the outlines of various plants can be combined by determining the first intersecting point and the second intersecting point, and a certain calculated amount of a server can be saved.

In step S104, the following are included:

various planting areas located in the planting field are determined separately and compared with each attribute area.

For example, in this embodiment, the server determines various planting areas located in the planting field, and compares the various planting areas with the respective attribute areas.

Further, the above-mentioned "determining various planting areas located in the planting field and comparing the various planting areas with the various attribute areas" includes the following steps:

For example, in this embodiment, the server may obtain a planning center point corresponding to the preset planning chart and a site center point corresponding to the site view, and place the preset planning chart on the site view in such a manner that the planning center point coincides with the site center point, and map each planning contour in the preset planning chart to the site view, so as to form each planting contour in the site view. At this time, the server determines the areas respectively surrounded by the respective planting profiles as corresponding to the respective planting areas located in the planting field.

Then, the server coordinates the field view, acquires various planting coordinate sections corresponding to various planting areas and various attribute coordinate sections corresponding to various attribute areas, and compares the various planting areas and the various attribute areas according to the various planting coordinate sections and the various attribute coordinate sections.

The embodiment can coordinate the field view, so that the comparison result of comparing various planting areas with various attribute areas is more accurate.

In step S106, the following are included:

And determining the planting area as a blending area in response to any planting area having a coincidence relation with at least two attribute areas and the at least two attribute areas having corresponding different plant attributes.

For example, in this embodiment, when any one planting area has a coincidence relationship with at least two attribute areas and at least two attribute areas correspond to different plant attributes, it means that a planted plant with different plant attributes is planted in the one planting area, and a subsequent server is required to irrigate and allocate the area so as to meet the irrigation requirements of different planted plants. Thus, the server will first determine the planting area as the deployment area.

Further, the above-mentioned "determining a planting area as a blending area in response to any planting area having a coincidence relation with at least two attribute areas and the at least two attribute areas having corresponding different plant attributes" further includes the steps of:

For example, in this embodiment, the server determines each coordinate overlap ratio between each attribute coordinate section and each planting coordinate section, and when the coordinate overlap ratio is greater than the preset overlap ratio, the server indicates that the attribute area corresponding to the coordinate overlap ratio and the planting area have a greater overlap relationship, so the server determines the attribute area corresponding to the coordinate overlap ratio greater than the preset overlap ratio as having an overlap relationship with the planting area.

When any one planting area has a coincidence relation with at least two attribute areas, the server further determines each plant attribute corresponding to the at least two attribute areas. When it is determined that each plant attribute includes both potting attributes and field attributes, the server determines the planting area as a deployment area.

In step S108, the following are included:

and carrying out regional division on the allocation region based on the coincidence relation to obtain a potting allocation region corresponding to the potting attribute and a ground allocation region corresponding to the ground allocation attribute, and obtaining a first regional proportion corresponding to the potting allocation region and a second regional proportion corresponding to the ground allocation region.

For example, in this embodiment, the server performs region division on the deployment region based on the overlapping relationship, so as to obtain a potting deployment region corresponding to the potting attribute and a ground deployment region corresponding to the ground deployment attribute, and then obtains a first region proportion corresponding to the potting deployment region and a second region proportion corresponding to the ground deployment region.

In step S110, the following are included:

For example, in this embodiment, the server may retrieve a preset deployment policy adapted to the deployment area according to a comparison result between the first area ratio and the second area ratio, so as to irrigate and deploy the plant field.

Further, the above-mentioned "irrigation allocation of the plant field by adjusting the preset allocation policy adapted to the allocation area based on the comparison result between the first area ratio and the second area ratio" further includes the following steps:

For example, in this embodiment, the server compares the first area ratio with the second area ratio, so as to obtain a comparison result, and determines the comparison result as the irrigation water amount ratio of the attribute area corresponding to the potting attribute and the attribute area corresponding to the planting attribute. For example, if the comparison result of the first area ratio and the second area ratio is 3:2, the irrigation water quantity ratio of the attribute area corresponding to the potted plant attribute and the attribute area corresponding to the corresponding potted plant attribute is 3:2.

Because the irrigation water quantity proportion obtained through calculation can possibly come in and go out from the actual situation, training adjustment parameters are set in the server, so that the management end can adjust the irrigation water quantity proportion according to the actual irrigation situation, and more accurate irrigation water quantity proportion is obtained. Therefore, the server will send the irrigation water ratio to the management end for display processing, and when the management end is judged to adjust based on the irrigation water ratio, the server will train the adjustment parametersAnd obtaining, and performing operation judgment on the adjustment data input by the management end.

When the server judges that the adjustment data input by the management end is configured to carry out amplified adjustment on the irrigation water quantity proportion, training adjustment parameters are carried out based on the adjustment dataWhen the server judges that the adjustment data input by the management end is configured to reduce and adjust the irrigation water quantity proportion, the server can adjust the training adjustment parameters based on the adjustment dataAnd performing reduction training so as to obtain updated training adjustment parameters.

Further, the method further comprises the following steps:

For example, in this embodiment, the server acquires a potting area image corresponding to the potting deployment sub-area, and performs image recognition on the potting area image, so as to determine the number of potting in the potting deployment sub-area, that is, the number of movable potting.

Then, the server will retrieve the preset number of movements and compare the number of movable pot plants with the preset number of movements. When the number of the movable potted plants is smaller than or equal to the preset number of movement, the number of the movable potted plants is smaller, and the movable potted plants are suitable for being moved by workers on the planting sites. Therefore, when the number of the movable potted plants is smaller than or equal to the preset number of the movable potted plants, the server determines each empty area of each attribute area corresponding to the potted plant attribute according to the field view, and trains the preset potted plant sample set to obtain the average potted plant size, so that the number of the potted plants which can be accommodated in each empty area, namely the number of the accommodated potted plants, is determined according to the average potted plant size.

Then, the server performs region combination on each empty region according to the number of the movable potting, so as to obtain each empty region group. When each empty region group contains the same number of empty regions as the number of movable potting, the server directly determines the empty region group as a movement position corresponding to the movable potting.

When each empty area group comprises all empty areas which are correspondingly larger than the number of the movable potted plants, the irrigation range extends from the water outlet to the periphery, and if the movable potted plants can be moved to the empty areas in a concentrated state, the irrigation effect can be better improved. Thus, the server determines each of the empty areas in a concentrated state, which has the same number as the number of the movable potting, as a movement position corresponding to the movable potting.

When each empty region group comprises each empty region corresponding to the quantity of the movable potted plants and each empty region which is in a concentrated state and is the same as the quantity of the movable potted plants does not exist, the server determines each empty region which is in a straight state and is the same as the quantity of the movable potted plants as a moving position corresponding to the movable potted plants.

After the mobile position corresponding to the movable potted plant is determined, the server triggers the voice broadcasting module to conduct voice broadcasting according to the mobile position, so that workers in the planting field can move the movable potted plant to the corresponding mobile position according to the voice broadcasting.

According to the embodiment, when the number of the movable potted plants is small, the position suitable for placing the movable potted plants can be determined in each empty area of each attribute area corresponding to the potted plant attribute, so that a certain water saving amount is improved.

According to the scheme of the invention, the server can firstly acquire the field surface view corresponding to the planting field, so that the attribute areas corresponding to different plant attributes are determined in the planting field according to the field surface view. The server determines each of the various planting areas located in the planting field, respectively, to compare the various planting areas with the respective attribute areas. When a planting area and at least two attribute areas have a coincidence relation and at least two attribute areas correspond to different plant attributes, the planting area is planted with different plant attributes, and in order to meet irrigation requirements of the planting plants with different plant attributes, a server determines the planting area as a blending area, and then performs area division on the blending area based on the coincidence relation, so that a potting blending sub-area corresponding to potting attributes and a ground planting blending sub-area corresponding to ground planting attributes are obtained. And then, the server acquires a first area proportion corresponding to the potting allocation subarea and a second area proportion corresponding to the ground allocation subarea, and invokes a preset allocation strategy matched with the allocation area according to a comparison result between the first area proportion and the second area proportion, so that irrigation allocation is carried out on the plant field. The invention not only can improve the corresponding irrigation effect, but also can improve certain water saving amount.
