BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to agricultural/aquacultural systems and methods. More specifically, the present invention generally relates to sustainable agricultural/aquacultural systems and methods. Even more specifically, the present invention generally relates to smart sustainable agricultural/aquacultural systems and methods for growing products, such as flooded grain crops and aqueous organisms.
2. Discussion of the Related Art
With respect to agriculture, this endeavor is generally defined as the farming of food, such as plant, animal, e.g., herd animals and poultry, and life forms in between plant and animal, such as fungi, e.g., mushrooms. Agriculture has been instrumental in the development of human civilization and includes growing crops as well as animal husbandry for the main purpose of creating food surpluses for the benefit of human society. Agriculture includes many farming techniques, such as tilling soil, providing irrigation, and herding livestock. A specific technique includes hydroponics, such as in growing tomatoes, for example.
Since ancient times, self-subsistence farming has been used and is still popular in undeveloped and developing countries. In developed countries, agriculture includes a wide range of farming techniques, such as sustainable agriculture, e.g., permaculture and organic agriculture, and intensive farming, e.g., industrial organic agriculture and commercial agriculture. Modern agriculture also involves genetic alteration, pesticides, and fertilizers.
One form of agriculture involves the use of flooding fields, ponds, or bogs for crops, such as rice, organic rice, wild rice, cranberries, and the like. The related art method for cultivating rice is flooding the fields while, or after, planting young seedlings. This related art method requires extensive manual water management, e.g., planning and servicing, of the water as well as extensive construction, e.g., damming and channeling, for the fields. Although flooding is not mandatory in growing rice or organic rice, all other methods of irrigation require extensive effort in weeding, controlling pests, and fertilizing.
Another example of a crop, being grown using flooded agriculture, is wild rice, a dark grain which grows in shallow water, such as small lakes and slow-flowing streams, such as found in Canada, northern United States, and parts of Asia. Typically, the flowering head of the wild rice plant is disposed above water level. Before 1965, most wild rice in the United States was produced in natural stands, such as lakes, rivers, and streams. In Canada, most wild rice is still produced in lakes and streams that are leased from the government. Growing wild rice as a field crop was suggested in the 1850s, but significant efforts did not begin until about 1950 when James and Gerald Godward began to grow wild rice in a one-acre diked and flooded field (reservoir) near Merrifield, Minn.
Yet another example of a crop, being grown using flooded agriculture, is the cranberry, a fruit that is grown in wet, marshy areas, such as bogs. Cranberries grow best in climates having a cool growing season without extreme cold. Cranberry farms are mostly found in the Canadian provinces of Nova Scotia, Quebec, Ontario, and British Columbia. In the United States, they are grown in Massachusetts, New Jersey, Wisconsin, Oregon, and Washington. The marshy cranberry bogs have peat formed at the bottom when dead plants fall and disintegrate. The cranberry “beds” comprise sand and peat. Banks are typically formed around these cranberry beds. Ditches are typically formed around the cranberry beds, whereby a farmer manually feeds water from a holding area having a higher elevation.
In addition to conventional crops, a specialized category of agriculture, called aquaculture or aquafarming, is generally defined as the farming of freshwater and saltwater organisms, such as finfish, mollusks, crustaceans, and aquatic plants, such as seaweed. Aquaculture involves cultivating aquatic organisms, under somewhat controlled conditions, in contrast to commercial fishing, being defined as the harvesting of wild fish.
For example, a form of aquaculture is mariculture, being defined as the practice of aquaculture in a marine environment. Other forms of aquaculture include algaculture, being defined as the practice of growing kelp/seaweed and other algae, fish farming, shrimp farming, oyster farming, the culturing of pearls, and the growing of ornamental fish. Some specific techniques include aquaponics, which integrates fish farming and plant farming.
Although primitive techniques, such as flooded rice reservoirs and oyster beds, have been largely replaced with commercialized and industrialized farming operations, these modern techniques remain inefficient, unsustainable, and largely uncontrolled.

Still referring to FIG. 6, each gate control unit 30 draws power, in an on-demand basis, from either the battery or the solar power device 32. The remote gate 31 performs in response to instructions received from the associated mesh network module 40 for controlling a fluid level of the at least one growth reservoir 5. The motor 36 operates the remote gate 31 by actuating the sliding weir gate 33. Since the at least one gate control unit 30 further comprises a sliding weir gate 33 and a motor 36 coupled with the remote gate 31 for actuating the sliding weir gate 33, the remote gate 31, being disposed into a levee of the at least one growth reservoir 5, is actuated in response to at least one instruction transmitted via the corresponding mesh network module 40 for controlling a level of the fluid 6 in the at least one growth reservoir 5. For example, the motor 36 actuates a wheel 37 disposed at a top of the remote gate 31, whereby the sliding weir gate 33 translates in response thereto, and whereby a level of the fluid 6 in any two growth reservoirs 5 is adjusted as needed in accordance with instructions transmitted from the corresponding or associated mesh network module 40. The probe 80 measures the fluid level, the water temperature, and any other water quality levels, such as a measurement of pH and a measurement of chlorophyll concentration. The probe 80 wire or wirelessly communicates with the associated mesh network module 40. The associated mesh network module 40 relays on/off commands to the motor 36 and transmits data from the probe 80 to the main control unit 10 for analysis and processing.

Referring next to FIG. 10, this schematic diagram illustrates a wire or wireless network 200 of a smart sustainable agricultural/aquacultural system 100, in accordance with an embodiment of the present invention. For example, a controller box (not shown), containing an associated mesh network module 40, may be coupled on the side of the electric box 23. The wire or wireless network 200 comprises at least one mesh network module 40 (see FIG. 1) in wire or wireless communication with at least one element, such as the at least one weather station (not shown), the main control unit 10, and any other at least one mesh network module 40. The plurality of mesh network modules 40 may comprise a host or coordinator module 44. For example, a mesh network module 40 of the plurality of mesh network modules 40, associated with a main control unit 10, may comprise a host or coordinator module 44; a mesh network module 40 of the plurality of mesh network modules 40, associated with a pump control unit 20, may comprise an end base 45; and a mesh network module 40 of the plurality of mesh network modules 40, associated with a gate control unit 30, may comprise a router 46. If the system 100 comprises a wire network 200, at least one wire (not shown) may run in a range of approximately 10 feet to approximately 20 feet between the at least one remote gate 31 and a levy (not shown).
Still referring to FIG. 10, each mesh network module 40 of the plurality of mesh network modules 40 is in wire or wireless communication with another mesh network module 40 of the plurality of mesh network modules 40, wherein all mesh network modules 40 of the plurality of mesh network modules 40 in the wire or wireless network 200, are interconnected. The routers 46 are in wire or wireless communication with one another and with either end base 45 or a host or coordinator module 44. For example, the wire or wireless network 200 may comprise three gate control units 30, wherein their associated mesh network modules 40 are in wire or wireless communication with one another as well as with the main control unit 10.
Still referring to FIG. 10, in operation of the system 100, the wire or wireless network 200 does not require that all mesh network modules 40 of the plurality of mesh network modules 40, e.g., in the field, be in direct communication with a host or coordinator module 44. As long as each mesh network module 40 is in wire or wireless communication with another mesh network module 40, all modules 40 of the plurality of mesh network modules 40 in the wire or wireless network 200 become interconnected. The plurality of mesh network modules 40, that are disposed at a distance and/or that are too far from the host or coordinator module 44 to effectively transmit a signal, perform signal-hopping through another mesh network module 40 until the signal is eventually received by the host or coordinator module 44. The signal received by the host or coordinator module 44 comprises the sum of the signals being sent from all mesh network modules 40. For example, a mesh network module 40 that may be associated with a main control unit 10 may comprise a host or coordinator module 44; a mesh network module 40 that may be associated with a pump control unit 20 may comprise an end base; and a mesh network module 40 that may be associated with a gate control unit 30 may comprise a router (not shown). The router transmits signals up and down a communication line of the mesh network to the host or coordinator module 44 while each end base only sends and receives signals. For example, a system 100, comprising a wire or wireless network 200, may comprise three gate control units 30, wherein each gate control unit 30 of the three gate units 30 performs a distinct task or a distinct set of tasks. The host or coordinator module 44 downloads on/off commands for relaying a signal to the pump control unit 20 and uploads a flow rate from the flow meter 22. A mesh network module 40 that is associated with a gate control unit 30 downloads on/off commands for relaying a signal to the motor 36, uploads and transmits data, concerning a water level gleaned from the probe, to the main control unit 10, uploads and transmits data, concerning a water temperature gleaned from the probe, to the main control unit 10, uploads and transmits data, concerning any other water quality measurements, to, or from, any mesh network module 40 to, or from, the main control unit 10. The main control unit 10 uploads data concerning an air temperature from the weather station to the computer 11, uploads the main control unit 10 humidity from the weather station to the computer 11, uploads data concerning wind speed from the weather station to the computer 11, and transmits data to, and from, any other mesh network module 40 to, or from, the computer 11.
