Description

TITLE OF THE INVENTION: AN APPARATUS FOR AUTONOMOUS PRECISION FARMING AND MANAGEMENT
FIELD OF THE INVENTION
The present disclosure is generally related to an apparatus for autonomous precision farming and management.
BACKGROUND OF THE INVENTION
Farming of crops is required to feed the ever growing human population. However, current farming practices suffer from the following drawbacks:
Existing automation systems are not designed for precision agriculture with crop- specific knowledge and intelligent built-in. To carry out such precision farming using existing systems, various sensors and controllers have to be procured from many vendors and integrated to give a single meaningful solution. Off the shelf precision farming technology platforms do not exist.
Existing automation systems feature time -bound irrigation or volumetric irrigation, and are not based on real-time water requirement of the soil. Most of these systems that are currently available are exorbitantly expensive. Such systems may cause either over or under utilization of water, resulting in poor performance of crops, in addition to leading to water scarcity. Likewise, they may also cause over or under utilization of fertilizers, resulting in poor performance of crops, in addition to leading to soil degradation.
Existing systems also do not predict the fertilizer requirements, leading to over or under stocking. Likewise, they are also not capable of forecasting the yield and connecting buyers, resulting in last minute rush in sale of produces
There is, therefore, a need in the art for an apparatus for end-to-end autonomous precision farming and management that overcomes the aforementioned drawbacks and shortcomings. SUMMARY OF THE INVENTION
An apparatus for autonomous precision farming and management is disclosed. The apparatus comprises at least one control unit that is configured to monitor and control the operations of the apparatus, said at least one control unit being configured to be communicatively associated with a server.
At least one crop sensing mechanism comprises at least one crop sensing device that is configured to detect at least one parameter in relation to a crop and transmit the detected at least one parameter to the at least one control unit.
At least one irrigation sensing mechanism comprises: at least one irrigation sensing device; and at least one rain sensing device that is configured to detect rainfall, said at least one irrigation sensing device and said at least one rain sensing device being associated with at least one irrigation system. The at least one irrigation system comprises at least one pump and at least one unit that supplies water from the pump to a crop, said irrigation system being continuously monitored by the at least one irrigation sensing mechanism when irrigation is on.
At least one nutrient sensing mechanism, comprises at least one tank with pump, with at least one nutrient sensing device being associated with the at least one tank.
The server is configured to: comprise at least one analytical module and at least one extensive knowledge base to support the at least one analytical module; and calculate the minimum stock requirement for a farm and place an order on behalf of a user automatically.
Said at least one analytical module is configured to analyse the current status of the crop and its environment, and suggest remedial action, if any, based on the information in the respective extensive knowledge base. Said at least one extensive knowledge base is configured to learn and improve itself based on the data received continuously from the other components of the apparatus. An application installable on a computing device is configured to geofence a farm and control the apparatus remotely, said application installable on a computing device being communicatively associated with the server.
The disclosed apparatus offers the following advantages: approximately 50-60% reduction in water usage; approximately 20-35% increase in productivity; leaves the least possible residues of farm inputs in the soil, which ensures the farms are maintained fertile for longer period; optimized stock maintenance; purchasers are able to know well in advance the possible farm produces, and, similarly, suppliers/farmers are able to plan their production; and service providers are able to understand the service needs of all farms in their neighbourhood and optimally utilize their resources.

DETAILED DESCRIPTION OF THE INVENTION
Throughout this specification, the use of the word "comprise" and “include” and variations such as "comprises "comprising", “includes”, and “including “implies the inclusion of an element or elements not specifically recited. Throughout this specification, the use of the term ‘user’ or ‘users’ is to be construed as being either at least one farmer or at least one buyer/purchaser, depending on the context.
Throughout this specification, the use of the word “apparatus” is to be construed as a set of technical components that are communicatively associated with each other, and function together as part of a mechanism to achieve a desired technical result.
An apparatus for autonomous precision farming and management is disclosed. The apparatus comprises at least one control unit (1) that is configured to monitor and control the operations of the apparatus, at least one crop sensing mechanism (2), at least one irrigation sensing mechanism, at least one nutrient sensing mechanism, and an application installable on a computing device (15).
The at least one control unit (1) is configured to be communicatively associated with a server (17). The server (17) is configured to comprise at least one analytical module and at least one extensive knowledge base to support the analytical module. The at least one analytical module is configured to analyse the current status of a crop and its environment, and suggest remedial action, if any, based on the information in the respective extensive knowledge base.
The current status of the crop and its environment, and the knowledge bases include, but are not limited to moisture content, temperature, pH, electrical conductivity, fertilizer levels, pest infection, insect infection, damage by rodents, virus infection, disease infection, weed infection, genetic disorders, and irrigation status.
The at least one extensive knowledge base is configured to learn and improve itself based on the data received continuously from the other components of the apparatus.
The at least one crop sensing mechanism (2) comprises at least one crop sensing device (3) that is configured to detect at least one parameter in relation to a crop and transmit the detected at least one parameter to the at least one control unit (1). The at least one parameter includes, but is not limited to, soil temperature, soil moisture level, root temperature, root moisture level, soil pH, soil electrical conductivity, and the level of at least one nutrient in the soil.
The at least one crop sensing mechanism (2) may also include at least one image sensor that is configured to capture images of the crop at pre-defined intervals and transmit the captured images to the at least one control unit (1).
The at least one irrigation sensing mechanism comprises at least one irrigation sensing device (9) that is associated with at least one irrigation system. The at least one irrigation system comprises at least one pump (10) and at least one unit that supplies water from the pump to the crop.
While the irrigation is on, the at least one irrigation sensing mechanism continuously monitors the irrigation system, and, if any abnormalities are identified, it shuts down the respective irrigation system and sends an alert to the at least one control unit (1). The monitoring of the irrigation system includes, but is not limited to, voltages, leakages, and dry run.
The at least one irrigation sensing mechanism also comprises at least one rain sensing device that is configured to detect rainfall, said rain sensing device being associated with the at least one irrigation system. If rainfall is detected, the at least one irrigation sensing mechanism shuts down the respective irrigation system sends an alert to the at least one control unit (1).
If the at least one control unit (1) determines a need for irrigation: it instructs the respective crop sensing mechanism(s) (2) to open at least one valve (4) and get ready for irrigation; the respective crop sensing device(s) (3) turns on the at least one valve (4) and sends a status update back to the at least one control unit (1); the at least one control unit (1) instructs the respective irrigation sensing mechanism(s) to start the respective pump(s) (10); the respective irrigation sensing device(s) (9) turns on the pump(s) (10) if grid power if available and the quality of power is within a tolerance limit; if a generator (16) is configured and grid power is unavailable, it is turned on until power is available; the at least one control unit (1) determines that the respective crop sensing device(s) (3) and the respective irrigation sensing device(s) (9) are operating properly by constantly communicating with them real-time; and in case of any failure, the at least one control unit (1) ensures safe turning off of the at least one valve (4), the respective pump(s) (10), and the generator (16). When the at least one control unit (1) determines that the irrigation can be completed, it informs the respective crop sensing mechanism(s) and the respective irrigation sensing mechanism(s) to close the at least one valve (4) and shut the respective pump(s) (10), respectively..
As the irrigation is carried out to maintain the moisture of the root zone, over or under irrigation is avoided, thus ensuring proper water usage, which saves over 50% of water compared to irrigation without sensing the requirement.
The at least one nutrient sensing mechanism comprises at least one tank (7) with pump, with at least one nutrient sensing device (6) being associated with the tank (7). If the at least one analytical module determines that the supply of at least one nutrient to the crop is due as per schedule, or if there is any deficiency in the level of the at least nutrient based on its detection by the at least crop sensing mechanism, then, the at least one control unit (1) sends instructions to turn on the respective irrigation system, in addition to: identifying the nutrients and calculating their respective quantities for that day, creating a batch, and estimating the total time requirement for the entire batch to be completed; estimating the approximate time required for the roots to get the required moisture level based on the current moisture level; identifying the respective nutrient sensing device (6) and the tank (7) responsible for the nutrients to be supplied; estimating the right time to start fertilization in ensure that the completion time of the batch coincides with the time required to get the right moisture levels; shutting off the nutrient supply after the dispensing of the required quantities, and transmitting the information to the at least one control unit (1); and calculating a cooling period after the completion of the batch, said cooling period being a period of time for which no irrigation is to be performed, said cooling period being instructed to both the at least one crop sensing mechanism and the at least irrigation sensing mechanism. A plurality of tanks facilitates the storing of fertilizer, pesticide, insecticide, rodenticide, virucide, weedicide, and the like. Though the above procedure has been illustrated with respect to fertilizer, the same may be carried out in respect of other parameters, including, but not limited to, soil pH, soil electrical conductivity, pest infection, insect infection, damage by rodents, virus infection, disease infection, and weed infection.
The at least one nutrient sensing mechanism continuously monitors the quantity of fertilizer in the at least one tank (7) and communicates the same to the at least one control unit (1). In case the quantity is determined to be inadequate for usage, the at least one control unit (1) transmits the information to the server (17), which, in turn, alerts a user with an estimated quantity of fertilizer that is required.
If the at least one control unit (1) determines a need for fertigation; it carries out everything needed for irrigation, and, additionally checks for the nutrients that are due for supply to crops as per the PoP at the start of the irrigation cycle; it ensures irrigation has successfully started, and waits for a predefined wait-time before starting to coordinate the supply of nutrients; during the wait-time, the at least one control unit (1) gets the list of nutrients to be supplied to the crop now, identifies the respective nutrient sensing device(s) (6) responsible for the supply for the nutrients, and the respective tank(s) (7) from where the nutrient is to be opened up; after completing the wait-time, the at least one control unit (1) takes one nutrient at a time, and, for each nutrient communicates with the right nutrient sensing device (6) to turn on a respective solenoid valve (8) of the tank (7) where the nutrient is stored, and also communicates the quantity to be dispensed to the respective nutrient sensing device (6); the respective nutrient sensing device (6) turns on the solenoid valve (8) so that the nutrient from the tank (7) can be injected into the irrigation pipeline; when the quantity of injected nutrient reaches the limit set, the respective nutrient sensing device (6) turns off the solenoid valve (8), thus stopping the supply of the nutrient; and the at least one control unit (1) then checks if there is any other nutrient needed to be supplied, if so for each such nutrient, it repeats the above steps until all nutrient supply is successfully completed.
As the fertilizer injection is accurately measured, there will not be under or over fertilization, which results in the correct amount of fertigation, resulting in savings of 30% of fertilizers, in addition to ensuring no soil degradation.
