Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The unmanned farm adopts new generation information technologies such as the Internet of things, big data, artificial intelligence, 5G, intelligent equipment, robots and the like, and an all-weather, whole-process and whole-space unmanned production operation mode of all farm production operations is completed by remote control, whole-process automatic control or robot autonomous control on facilities, equipment, machines and the like. The unmanned farm solves the problem of labor shortage through a robot changing mode, and achieves standardized, refined and intelligent production management. The unmanned farm has the characteristic of integrally planning land mass production by large-scale intensive design, and the vegetable mass production degree is deepened.
The key to unmanned farm crop management is water and fertilizer management, wherein the most basic process of vegetable production is irrigation and drainage of farmlands. In the crop planting management process of the unmanned farm, the waterlogging has a large influence on production, soil ponding is easily caused by the waterlogging, the soil air permeability is reduced, the root systems of crops cannot breathe normally, and the crop roots are easily affected by bacteria and diseases, so that the yield is reduced.
In actual irrigation, the irrigation water source is often far away from the farmland to be irrigated, and at the moment, the water supply plug for leading the irrigation water in the irrigation water source to the field head is needed by adopting a water conveying and distributing pipe network. For fine irrigation, the water and fertilizer integrated machine and the drip irrigation belt are combined to perform water and fertilizer irrigation. The optimization of the field water conveying and distributing pipe network can reduce the investment cost of agricultural production and improve the design level and efficiency of the field irrigation pipe network engineering. Therefore, on the premise of meeting the system flow, irrigation intensity and reliability, an optimal scheme of a water delivery and distribution pipe network is sought, so that the agricultural production investment is reduced, and the economic benefit of an irrigation system is improved, and the method has very important significance for the development and popularization of water-saving irrigation technology in China. The water distribution network layout needs to consider many factors such as designer's experience, crops and topography of planting, and the investment that causes the water distribution network layout is big, in order to reduce investment, saving expense, before carrying out the water distribution network layout, carry out the optimization analysis to the water distribution network, seek reasonable layout scheme. Most drip irrigation system designs do not allow for optimization of the field distribution network. According to the actual condition of unmanned farm field irrigation, a net-shaped drip irrigation belt is used for conveying and distributing water and fertilizer.
Under the large-area vegetable planting scene of the unmanned farm, the integral irrigation and drainage scheme of the land block is missing. Through extensive analysis, the main disadvantages of the prior art are found as follows:
firstly, in the aspect of ridging, the ridge body design is mostly carried out by considering the influence of illumination on ridging, so that the method is difficult to be applied to large-area non-shielding unmanned farm planting areas;
secondly, the farmland ditch construction usually considers the topography of the land, the ground surface fluctuation is gentle through rotary tillage and land leveling stages before the actual unmanned farm planting, the overall topography can be known to show a uniform descending trend through elevation measurement, and compared with the general farmland ditch construction, the farmland ditch construction has obvious scene characteristics;
thirdly, unmanned farm large tracts of land plots, along journey pressure gradually reduces when there is drip irrigation pipeline irrigation, and pipeline design is unreasonable causes along journey liquid manure medicine distribution homogeneity poor easily, irrigates unevenly, causes crop growth process inequality or pipeline head to spray liquid manure too much and cause the nutrient waste, and tail end liquid manure supply is not enough, and plant growth is short and low in output etc..
In order to realize unmanned farm vegetable planting drainage planning and design and support unmanned continuous operation, the unmanned farm ditch building and pipeline laying scheme generating method and device provided by the invention adopt elevation equipment to collect geographic information according to the real unmanned farm physical environment, and plan an algorithm of ridging direction and ditch repairing position based on surface flow analysis; according to the relation among the vegetable types, the ridge length, the ridge surface width and the drip irrigation belt along-line pressure, a water and fertilizer pipeline laying scheme is designed, the water and fertilizer is conveyed and distributed by using the meshed drip irrigation belt, the field water conveying and distributing pipeline network is optimized, unnecessary manual participation can be reduced under an unmanned farm scene, the disaster occurrence probability is reduced, and unmanned production management is facilitated.

And according to the elevation measurement topography trend information, determining the ridging direction and the canal repairing direction of the target land block. For example, when the north-south ground potential difference is higher than the east-west ground potential difference, the ridging direction is east-west, the canal direction is set to be north-south, and a canal is built on the side with low topography, so that drainage is facilitated; when east-west land potential difference is higher than north-south land potential difference, the ridging direction is north-south, the canal direction is set to be east-west, and a canal is built on the side with low topography, so that drainage is facilitated.

The balance of irrigation is a key for orderly growth of plants, the water and fertilizer amount difference at the head end and the tail end is smaller by considering the along-path pressure of an irrigation pipeline, and the irrigation is guided by adopting a partition strategy for large-area unmanned farm plots. In actual irrigation, all pipeline systems are almost composed of a plurality of equal straight pipe sections and a plurality of pipeline accessories, so that in one pipeline system, the along-line loss and the local loss exist.
Wherein, measure the pipeline pressure of the sample plot, in order to carry on the branch pipeline pressure distribution calculation:
(1) Obtaining the minimum working pressure by selecting the tail end of the pipeline with the maximum head loss as a measuring point;
(2) On the basis of the minimum working pressure, the head loss of the pipe section, namely the pressure head of the last node, is added in sections;
(3) And by analogy, calculating the pressure head required for the inlet of the pipeline.
When the split-flow water pump is paved, the farm is mainly partitioned, a plurality of pipes are considered, each pipe is long, and in order to ensure the water filling uniformity of each split-flow point, the total head loss along the maximum head loss branch is not more than 20% of the inlet pressure head loss. The drip irrigation pipe is the longest position, and the main pipeline is connected in parallel at the position to partition the target land block into a plurality of sub-land blocks.
Vegetable is planted on the ridge surface, and according to the vegetable growth space requirement, n rows (n > 2) are planted on one ridge, and most of the rows are 2-4. And paving n-1 to n drip irrigation pipes on the ridge surface. The irrigation mode and pipe diameter of the sample land parcels are the same as those of the target land parcels.
The pipelines are paved on the ridge surface, the length of the pipelines on the ridge surface is the same as the width of the subareas, and water flows in the pipelines from the side with high topography to the side with low water flow.

And the head and tail uniform irrigation is realized by adopting a main pipeline partition method.
