Problems solved by technology

[0003] Among them, irrigation needs to pay attention to the following problems. Frequent mowing makes the plants form shallow roots, which reduces the water absorption capacity of the plants from the soil, and the soil contains a lot of sand with poor water retention capacity, so it is necessary to keep the lawn in this area in good condition. Must be watered frequently and also sprayed for a few minutes in the middle of the day when the heat is dry
In addition, in some special environments, such as stadiums, in order to water, the watering time is generally arranged in the evening, but at this time the temperature and sunlight are relatively low.

Embodiment 1

[0051] Calculate the displacement of various types of grassland in different regions:

[0052] Such as figure 1 Shown is a schematic diagram of the golf course site. The golf course is divided into tee area I, obstacle area II, putting area III and green area IV; each area can be planted with different types of grass, so that it can be decorated with different colors. Separate the regions. It should be understood that a golf course is used here as an example, but not limiting, and the field may be applicable to other planting applications. For example, areas such as mixed crops in farmland. In addition, it should be understood that the amount of water divided into different areas is different due to the water absorption of different crops (such as different grass species). For example, for the above-mentioned golf course, the mutual water absorption can be: putting area III>green area IV> tee area I> hazard area II.

[0053] In order to obtain the irrigation water volume o...

Embodiment 2

[0060] This embodiment includes the identification and area calculation of each grassland area in areas I, II, III, and IV. Embodiment 2 may include all the content of Embodiment 1, and the same parts as Embodiment 1 will not be repeated here.

[0061] Using the color information output unit of the golf course grass in the golf course image acquired by an image acquisition unit to calculate the relevant information of the tee area I, the obstacle area II, the putting area III and the green area IV, the information at least includes the information of each area Area; then the system will number each area of ​​the court, and use the number as an index number, and the boundaries between each area are calculated by using the numbering data and the position information of each area of ​​the system.

[0062] Utilize the vegetation type of the golf course, the specific parameters of the image acquisition device, the index number of each area, the preparation information of each area ...

Embodiment 3

[0092] Embodiment 3 includes all the contents of Embodiments 1 and 2, and the same parts as Embodiments 1 and 2 will not be repeated here.

[0093] Grassland evaporation calculation unit and method:

[0094] For each area I, II, III or IV, set up an experimental area with an approximate area of ​​1m 2 , the area of ​​the area can also be appropriately changed according to the size of the area, the experimental area can also be a part of the detection area; and the crops in the experimental area are the same as the crops in the area corresponding to the experimental area.

[0095] The specific calculation formula of evaporation can use the following Penman-Monteith formula to calculate the evaporation of grassland in the experimental area.

[0096] Use the penman-monteith (Penman-Monteith) formula to calculate the grassland evaporation formula, for example, it can be:

[0097]

[0098] Where ET is the reference crop evaporation; U is the specific heat of the gas at normal pr...

Abstract

The invention relates to an intelligent irrigation system and method, and belongs to the technical field of maintenance of mixed planting of various crops. The intelligent irrigation system comprises a database, a sensor system, an image acquisition device, a calculation unit and a watering system, the subsystems are connected by using the Internet of Things, and a database is correspondingly established, so that the intelligence of irrigation is realized. Wherein the experimental areas are arranged at the edge positions of different crop areas, so that the water discharge amount and the water absorption amount of each crop area can be flexibly and conveniently detected, and the required watering amount of each area can be obtained.

Description

technical field [0001] The invention relates to the field of maintenance, in particular to a site intelligent irrigation system for mixed crops. Background technique [0002] At present, to manage the growth of crops on special sites, issues that need attention include grass cutting, irrigation, fertilization, drilling for ventilation, soil addition, and pest control. These special venues include the mixed planting of different crops; for example, the mixed planting of different types of grass in football fields; the growth of different types of grass in golf courses. In golf courses, in order to be able to distinguish the tee area, obstacle area, hole area and fairway area, different types of grass species can be planted, and the differences in color can be used to distinguish them. Compared with hard isolation measures such as scribing, this method reduces the damage to the grass caused by the isolation equipment. Also reduces interference with golf balls. Similar probl...
