Definitions

  • the present invention relates to a System and a wireless Procedure for automation and control of technified irrigation that has been designed and constructed to be applied on any plantation of fruit trees, vegetables, gardens or the like, which possess technified irrigation equipment.
  • System and Procedure is that wirelessly and centrally, manages and controls, individually, each of the elements that activate and deactivate irrigation; also capture sensor data from multiple incident factors in
  • the profitability of the fruit business depends on the productivity and quality of the fruit that is obtained, so that the maximum rigor in the planning and execution of all agricultural tasks must be sought; among them one of the most important is irrigation and fertilization; and subsequently check that they have actually been executed according to plan.
  • the technified irrigation is made up of pumps that extract the water from a source (well, tranque, channel), Ia propel a pipe that forms a water network, which by means of electrically operated valves, allow to supply the irrigation lines in a sectorized way that have the drippers or micro sprinklers that are finally the ones who deliver the water to the plants.
  • a fertirrigador equipment is inserted, whose function is to feed one or more nutrients to the water network, which will be delivered to the plants.
  • the electrically operated valves also called solenoid valves, are connected with an electric wire to a controller that is programmed to indicate when they should be opened or closed. From that same controller, the starting and stopping order of the (or) pumps involved with said valves is given.
  • the fertirrigator is usually programmed in another control center or operated manually.
  • Irrigation is sized considering factors such as the surface and species to be planted; soil characteristics; The evapotransplration and temperatures of the area in the various seasons of the year; The planting density; and other related. Based on this, the maximum amount of water is determined per unit of time that needs to be delivered to the plants when they are in full production. Then, the irrigation system, number of pumps, fertirrigators, sector size, number and location of solenoid valves, number and type of irrigation emitters (drippers or micro sprinklers), diameters and layout of the network of electrical pipes and cables are designed .
  • the sectors in which the area to be irrigated is divided are established in order to optimize the use of resources such as pumps and fertirrigators; For example, given that the cultivated sectors will not be irrigated 24 hours a day, but perhaps a maximum of 3 hours per day, then up to 8 sectors can be irrigated using the same pumps for all of them.
  • the pumps are installed inside an irrigation booth, close to the water source, where the fertirrigator and the controllers with which the irrigation and fertilization are programmed are also installed. Considering that the drippers are very small holes, to prevent them from clogging up, the water extracted from the source immediately passes through a system of filters.
  • a frequent configuration for fruit crops such as avocado and citrus is that there are one or two pumps, located in an irrigation booth, for every 25 hectares that make up an irrigation garden. The surface is divided into 5 sectors each with 15 valves. Thus a field with 500 hectares of plantation will have: - 20 Irrigation systems, each with its irrigation booth and its controller for programming
  • the irrigation booths where the controllers for programming irrigation and fertilization are located, are far from the offices where the agronomist who defines how you want to water is located and also far from each other.
  • the controllers that are commonly used are very basic equipment, which fundamentally allow programming the opening time of a series of solenoid valves, and the closing time of these. They are similar to garden irrigation controllers.
  • the person responsible for irrigation based on multiple variables, such as evapotranspiration, ambient temperature, soil texture, planted species, wind, and others, defines how much and when to irrigate and fertilize. The more flexibility you have to implement the irrigation operationally, the person in charge can more easily find the way to achieve optimal irrigation.
  • a avocado plantation for example, it can be defined for a given week, which is desired to water every day of the week, 3 hours a day, starting at 11 am. To materialize it, this irrigation must be programmed in the controller, which does not present major difficulties. However, the matter becomes more complicated if it is defined that you want to water based on pulses instead of long times, for example water 8 minutes from 10 hours, then 12 minutes from 11 hours, and so successively until completing 8 pulses during all days of the week, with the exception of the Sunday day that a long watering of 4 hours from 13 hours is desired. Programming this type of irrigation already presents greater difficulties.
  • the person in charge of defining the irrigation presumes that it is really irrigated according to what he has established, however there are multiple factors that can distort it.
  • a first factor is that the person in charge of programming the irrigation does not do it correctly, which is difficult to detect.
  • a second factor is that the programmed irrigation has not been carried out or has been carried out only partially by power cut. Similar factors occur in the fertilization process.
  • the registration of the irrigation and fertilization data is of the utmost importance, since it allows the productivity of the plantation to be analyzed later, in relation to the aforementioned data, climatic and agronomic factors.
  • the productivity of plants depends not only on irrigation and fertilization, but also on weather conditions, such as falling rain, wind, solar radiation, temperatures at different times of the day and throughout The season, the humidity, among others. Having all this information is vital to program irrigation and fertilization, as well as to subsequently perform an analysis of these and their relationship with productivity.
  • Meteorological Stations are commercialized that measure and record these factors, at a reasonable cost.
  • said data cannot be seen in an integrated way with the information related to irrigation and fertilization, since they are provided with proprietary and specific software.
  • various sensors are used that allow measuring, for example, the soil moisture at different depths, the temperature of the leaves, the dilation and contraction of the trunk of the trees (dendrometers), among others.
  • these sensors are commercialized with a device that records the readings that are made, with a certain periodicity (for example every 1 hour). In general, these devices do not have the capacity to transmit this information to a central computer, except for those of high cost. Even less to integrate this data with information related to irrigation. Reviewing the state of the art in the Operation and Control of Irrigation, it can be concluded that the elements and devices currently available in the market, satisfy the basic needs of operation, however, because they are provided by multiple suppliers, their integration is practically nil. On the other hand, due to the traditional delay with which agriculture incorporates technology, automation and control systems so used in other industries such as manufacturing or mining have not been developed for example.
  • an object of the invention is to build an automation and control system for all the devices involved in technical irrigation. This will facilitate its operation and record all the information concerning the process in addition to designing and building an information system that integrates data related to irrigation, weather conditions, sensors and all other information that could be useful to achieve efficient agronomic management, oriented to obtain an optimum profitability in the plantations and with a total traceability of the executed one.

  • the pumps and solenoid valves are commanded by the irrigation controller or programmer and the fertirrigators are commanded by a second independent programmer.
  • Another object of the invention is to build an automation system that commands only pumps, fertirrigators and solenoid valves. Pumps and fertirrigadores are easily attainable, since both elements are located in the irrigation booth, very close to each other.
  • the solenoid valves are distributed over the entire surface of the plantation, which represents a major problem. These solenoid valves, commanded by the programmer, in general they receive 24-volt power supply to activate the device that opens them, and they are closed by the action of a spring when they stop receiving energy. Taking advantage of the possibility of obtaining energy from the solenoid valve, it is defined as another object of the present invention to build an electronic device that, powered by that energy, could act to open and close each solenoid valve.
  • This device should also be connected to a central computer in which it is programmed and from which the irrigation is commanded, based on individual opening and closing orders for each of them.
  • This configuration allows total independence to act on each valve individually, either manually or automatically.
  • Current systems have normally been constructed in such a way that several valves are grouped as garlands that are in unison open or closed, which offers little flexibility to make different risks in the areas of influence of each valve, if required.
