Agricultural products such as crop protection products, seeds or fertilizer are indispensable in agriculture due to their impact on yield and have a significant impact on environmental aspects. The application of agricultural products on an agricultural field is therefore an important issue in agricultural. Recommendations how to apply the agricultural products vary from theoretical basis in form of written documents to observations in form of human experts. These recommendations result e.g. in application rate maps for the agricultural product, which are used from a farmer for applying the product on the agricultural field.

The term product is to be understood broadly in the present case and comprises any product, which can be applied on an agricultural field. Preferably the products may comprise crop protection products, pesticide, fungicide, herbicide, insecticide, acaricide, molluscicide, nematicide, avicide, piscicide, rodenticide, repellant, bactericide, biocide, safener, plant growth regulator, urease inhibitor, nitrification inhibitor, denitrification inhibitor, fertilizers, seeds, water, etc. The term continuous means in the following a recurring activity (e.g. determining the position and adapting the product rate and/or frequency) along the path, whereby the recurring activity may be repeated e.g. every minute, every 30 s or 10 s or 1s or every 100 meter, 10 meter, 5 meter or 1 meter. The term continuous is the opposite of a singular event or uniquely. The term product relates to any physical state of the product, e.g. fluid, rigid or gaseous. The term agricultural field is to be understood broadly in the present case and comprises an area which is configured to serve as basis for growing of agricultural goods, e.g. wheat and rice. The agricultural field may comprise any shape or size. The agricultural field is not limited to a continuous area. The agricultural field may vary in its biological characteristics. The term control signal is to be understood broadly in the present case and comprises any analog or digital signals. The term product rate is in the present case to be understood as amount of a product per an area. The amount may be expressed in kilogram or liters. The area may be expressed in square meter or hectare. The product rate depends on the product and the characteristics of the agricultural field. For example a part of the agricultural field may comprise lots of weed such that the product rate of a specific pesticide may be accordingly high. The term frequency means in the present case the frequency of an application of an application device. For example, in case of an application of a pesticide on an agricultural field, the pesticide may be applied every time a weed is detected. In this case the detection of the weed may be carried out by sensor, wherein the sensor measures for example a reflected light from the weed. The trigger for applying the pesticide may be based on a comparison of the measured reflected light with a threshold. Hence, a change of the threshold is a possibility to adapt the frequency of applying the pesticide on the agricultural field. The term tank is to be understood broadly in the present case and comprises any element configured to store a product. The term tank preferably comprises in the present case hollow bodies. The term application device is to be understood broadly in the present case and comprises any device configured to apply a product on an agricultural field. Preferably the term application device comprises sower, fertilizer machine and sprayer. The application device may be self-propelled, towed by tractor or mounted on a tractor. The term route means in the present case a path of the agricultural device through the agricultural field. The route may be derived from tramlines in the field. The route may be a random path through the agricultural field (e.g. in case the agricultural field is a lawn). The route preferably comprises information of a length of the route. The agricultural device moves along the route. Based on the position of the application device along the route and an application width of the application device an area already treated by the application device may be determined. Based on the position of the application device in the route and the application width of the application device the remaining area to be treated by the application device may be determined. The predetermined amount of the product which should be in the tank at the end of the route can be defined in different ways, e.g. as an absolute number of the product, as product range with a minimum value and a maximum value, as percentage of the tank volume, as percentage range of the tank volume (e.g. 1 to 10 liters/kilograms; 50 liter/kilograms with a tolerance of +/−5 liters/kilograms; between 1.5 and 10% of the total tank volume; etc.).
The application device may by equipped with one or more treatment devices. The treatment device may be configured to collect field data via treatment components and/or sensor devices. The treatment device may be configured to sense field data of the agricultural field via the sensor device. The treatment device may be configured to treat the agricultural field via the treatment component.
The application device may be equipped with or operatively coupled with different apparatuses, for example a geolocation device, a communication interface, a sensor device, a control unit, a communication device, computing means and the like.
Additionally, the application device may comprise a sensor device for acquiring a measure of the amount of treatment and/or treatment product applied to the agricultural field. Treatment component(s) may be operated based on sensor signals provided by the sensor device(s) of the treatment device. The treatment device may comprise a communication interface and/or unit for connectivity. Via the communication unit the treatment device may be configured to provide, receive or send field data, to provide, send or receive operation data and/or to provide, send or receive control data.
In other words, the invention is based on the knowledge that at the end of the application of the product along the route there is either too much product in the tank of the agricultural device or too little product in the tank of the agricultural device. In case there was too little product in the tank, it was not possible to cover the complete area of the agricultural field with the product. This means that the tank of agricultural device has to be refueled with the product again to apply the remaining area with the product. This is disadvantageous in terms of cost and time and could lead to too little or too much product in the tank. In case there is too much product in the tank at the end of the application, unused amount of the product must be disposed of. This is disadvantageous in terms of disposal costs and time. After receiving a start signal, the disclosed method determines the current amount of product in the tank and the current position of the agricultural device along the route. For example, the route may be provided by a tramline, a driving path and/or an area already covered reveals in combination with a working width of the application device the already treated area of the application device. Based on the length of route still to be covered and the amount of product still in the tank, the method now adapts the product rate and/or the frequency of the application device inside predefined ranges, such that the amount of the product in the tank has a certain value at the end of the route (e.g. zero or 50I as buffer). For example, the application rate and/or frequency can be increased, if the amount of product in the tank is too large such that the tank is empty at the end of the route. This could be advantageous as no time consuming and costly disposal of the product is necessary. For example, the application rate and/or frequency can be lowered in case the amount of product in the tank is too low, so that all areas or plants along the route can be treated without refilling the tank. This could be advantageous as it ensures a complete treatment of the area along the route.
In an embodiment the control signal to start the adaptation of the product rate and/or of the frequency is based on a manual input and/or an automatic input, wherein the automatic input is preferably based on an initial length of the route and the current position of the application device in the route through the agricultural field. The manual input may come from a user, e.g. farmer controlling the agricultural device. The automatic input may be triggered when a certain length of the route is already treated by the application device, preferably 0.5 length of the route, particularly preferred 0.66 length of the route and extremely preferred 0.75 length of the route. The automatic input may be triggered when a certain amount of the area of the agricultural field is already treated, preferably after 50%, particularly preferred after 60% extremely preferred after 75% or 80%. This may be advantageous, as it ensures that the tank may be empty at the end of the route or that the entire area may be treated with the product. The automatic input may be triggered by historical data of previous treatments and data from the current treatment. The automatic input may be triggered based on a machine learning algorithm, wherein the machine learning algorithm may be trained with historical data of previous treatments of the field to be treated.
In an embodiment the method is provided, wherein continuously determining the current amount of the product in the tank of the application device is based on at least one sensor configured to measure the amount of the product in the tank and/or continuously determining the current amount of the product in the tank of the application device is based on a calculation, based on an initial amount of the product in the tank of the application device and an amount of the product already applied on the agricultural field. The sensor may be a weight sensor, a fill level sensor. The sensor may provide continuously measurement values of the amount of the product in the tank to a determining unit via an interface (e.g. Ethernet, Profibus, etc.). This may be advantageous to precisely determine the amount of the product in the tank of the agricultural device. The initial amount of the product in the tank may be provided by a user input of the farmer or may be provided at a filling station when filling the tank. The amount of the product already applied on the agricultural field may be determined by a flow sensor of the application device, wherein the flow sensor measures the amount of the product already applied. The amount of the product already applied may be determined by integrating a distance of the route already covered with the application device and the corresponding application rates and/or frequency, wherein the application rate and/or frequency may be read out from an application rate map. This may be advantageously due to a cost efficient way to determine the amount of the product in the tank, as no additional sensor are required.
In an embodiment the method is provided, wherein continuously determining the current position of the application device in the route through the agricultural field is based on a Global Positioning System of the application device and/or a continuous analysis of a movement speed of the application device on the route through the agricultural field. An integration of the movement speed over a time leads to the current position of the application device in the route through the agricultural field. The Global positioning system may be advantageous to precisely determine the position of the application device. The analysis of the movement speed may be a cost effective alternative to determine the position of the application device, as no additional sensors are required.
In an embodiment the method is provided, wherein the product rate and/or the frequency is adapted within predefined ranges. The predefined ranges may be limited by thresholds, e.g. an upper threshold and a lower threshold, wherein below the lower threshold an application may be useless and above the upper threshold an application may be harmful to the environment. The predefined ranges may comprise more than two thresholds and/or different allowable combinations of thresholds. This may be advantageous to increase an efficiency of applying the product on the agricultural field.
In an embodiment the method is provided, wherein continuously adapting the product rate is further based on an application map of the product for the agricultural field. The term application map of the product comprises in the present case a map comprising product rates along the route. The product rates in the application map may serve as a basis for the adaption, such that product rate may be increased or decreased by e.g. 10% in comparison to the basis. This may be advantageous to reduce a deviation from the initial values of the application map with simultaneous emptying of the tank to the predetermined amount of the product in the tank.
In an embodiment the method is provided, wherein continuously adapting the frequency comprises the step of adapting a triggering threshold value for triggering the application device to apply the product on the agricultural field, in case a sensor signal is used for triggering an application of the product on the agricultural field. Measuring data from the sensor is compared to the triggering threshold value for triggering the application device. In case the measured data is below or above the threshold value the device is triggered to apply the product on the agricultural field or not. By adapting the threshold value the triggering is adapted and therefore the frequency of applying the product on the agricultural field. E.g. by reducing the triggering threshold also smaller accumulations of weed are detected. This may be advantageous for the targeted application of the product on the weed in the agricultural field with simultaneous emptying of the tank to the predetermined amount of the product in the tank. Preferably, based on the amount applied and/or corresponding product rates and/or corresponding frequency and/or triggering thresholds so far along the route, the amount still to be applied along the remaining route is estimated. Preferably based on the estimate and the current amount of the product in the tank and the current position, the product rate and/or the frequency are continuously adapted.
In an embodiment the method is provided, wherein the continuously adapting the product rate and/or the frequency is based on a forecast calculation, which is based on an amount of the product already applied on the route through the agricultural field and the remaining route through the agricultural field. The product already applied on the route may be determined by sensors, e.g. weight sensors. The product already applied may be indicative for a distribution of plants (e.g. weed, oils seed rape). Based on the distribution of plants a forecast calculation of the necessary amount for the remaining route may be derived. The forecast calculation may lead advantageously to a precise emptying of product in conjunction with an efficient treatment of the agricultural field.
In an embodiment the method is provided, wherein the route of the application device is laid out through several physically separated field units. This may be advantageous to increase the efficiency of applying a product on several agricultural fields, as calculation possibilities or the solution space are increased, which may lead to better results./
In an embodiment the method is provided, wherein continuously adapting the product rate and/or the frequency is further based on a predetermined number of tank fillings or on a predetermined total product quantity. This may advantageous for an increased efficiency, as a larger solution space is considered for adapting the product rate and/or the frequency.
In an embodiment the method is provided, wherein the product is a crop protection products, pesticide, fungicide, herbicide, insecticide, acaricide, molluscicide, nematicide, avicide, piscicide, rodenticide, repellant, bactericide, biocide, safener, plant growth regulator, urease inhibitor, nitrification inhibitor, denitrification inhibitor, fertilizer, seed, water, etc. In an example, the application device is continuously monitored in terms of position, applied amount of product, production rate and/or frequency.
A further aspect of the present disclosure relates to a system for applying a product on an agricultural field, comprising: a receiving unit configured to receive a control signal to start a continuous adaptation of a product rate and/or a frequency during a current application of the product on the agricultural field; a first determining unit configured to continuously determine a current amount of the product in a tank of an application device for applying the product; a second determining unit configured to continuously determine a current position of the application device in a route through the agricultural field; an adapting unit configured to continuously adapt the product rate and/or the frequency based on the current position of the application device in the route through the agricultural field and the current amount of the product in the tank of the application device such that at the end of the route of the application device through the agricultural field a predetermined amount of the product is in the tank. This may be advantageous to increase the efficiency of applying the product on the agricultural field. The receiving unit, the first determining unit, the second determining unit and/or the adapting unit may be separate hardware based CPUs, virtual software units executed one or more hardware CPUs.

The computer program element might therefore be stored on a computing unit, which might also be part of an embodiment. This computing unit may be configured to perform or induce performing of the steps of the method described above. Moreover, it may be configured to operate the components of the above described system. The computing unit can be configured to operate automatically and/or to execute the orders of a user.

According to a further exemplary embodiment of the present disclosure, a computer readable medium, such as a CD-ROM, USB stick or the like, is presented wherein the computer readable medium has a computer program element stored on it which computer program element is described by the preceding section. A computer program may be stored and/or distributed on a suitable medium, such as an optical storage medium or a solid state medium supplied together with or as part of other hardware, but may also be distributed in other forms, such as via the internet or other wired or wireless telecommunication systems. However, the computer program may also be presented over a network like the World Wide Web and can be downloaded into the working memory of a data processor from such a network. According to a further exemplary embodiment of the present disclosure, a medium for making a computer program element available for downloading is provided, which computer program element is arranged to perform a method according to one of the previously described embodiments of the present disclosure. A further aspect of the present disclosure relates to a control device configured to perform steps of the method described above, and a computer-readable medium which stores the computer program element described above.
In the following, the present disclosure is described exemplarily with reference to the enclosed figure, in which
The method below can be summarized as follows. The machinery is constantly monitored. Collected information can be product applied per area, position, machinery settings. As soon a start signal is received a current amount of a product in a tank of an application device and a current position of the application device in a route through an agricultural field are continuously determined. Based on the current position, a remaining distance along the route is determined. The remaining distance along the route in combination with the working width of the application device corresponds to the untreated area of the agricultural field. Based on the current amount of product in the tank and the distance remaining along the route or the area still to be treated along the route, the product rate and/or frequency of the application device is adapted such that at the end of the route there is a certain amount of the product in the tank. Preferably, based on the amount applied and/or corresponding product rates and/or corresponding frequency so far along the route, the amount still to be applied along the remaining route is estimated. Preferably based on the estimate and the current amount of the product in the tank and the current position, the product rate and/or the frequency are continuously adapted.
In a first step S10 a control signal to start an adaptation of a product rate and/or of a frequency during a current application of the product on the agricultural field is received by receiving unit. The control signal may be a manual input from a user, e.g. a farmer controlling the agricultural device. The control signal may be an automatic control signal, wherein triggered when a certain length of the route is already treated by the application device, e.g. 0.5 length of the route. The product is in the present case an herbicide for treating weeds. The agricultural field is in the present case a continuous field where corn is grown.
In step S20 a current amount of the product in a tank of an application device for applying the product is continuously determined by a first determination unit based on a treatment savings parameter. In the present example the current amount of the herbicide in the tank of the application device is determined by a fill level sensor applied on the surface of the tank. The application device in the present example is a sprayer mounted on a tractor.
In step S30 a current position of the application device in a route through the agricultural field is continuously determined by a second determination unit. The route through the agricultural field may describe a predefined path of the agricultural device through the agricultural field and a corresponding length. The position is in the present example determined by a Global Positioning System (i.e. GPS) that is arranged at the application device. Hence, it is possible to determine the remaining length of the route or remaining area to be treated. The route may describe a random path of the agricultural device through the agricultural field. Based on the position it may be determined whether the position is already treated by the application device. Based on the current position and a previous position of the agricultural device further a driving direction of the application device may be determined. Based on the driving direction of the application device a position of the sprayer with its corresponding working width may be determined.
In step S40 the product rate and/or the frequency are continuously adapted by a adaption unit based on the current position of the application device in the route through the agricultural field and the current amount of the product in the tank of the application device such that at the end of the route of the application device through the agricultural field a predetermined amount of the product is in the tank. In the present example of weed control the fill level sensor detects to high amount of the herbicides in the tank of the agricultural device. Hence the frequency is increased by adapting a triggering threshold value for triggering the application device to apply the herbicide on the agricultural field, wherein a weed detection sensor signal is used for triggering an application of the herbicide on the agricultural field. Further the product rate of the herbicide is increased. Hence, it is possible to reduce the current amount of the tank at the end of the route to a certain amount of the product in the tank, e.g. zero. Due to possible fluctuations in the distribution of weeds over the agricultural field, from a certain remaining distance/length of the route in this example the frequency and the product rate are increased to the maximum values (i.e. a so called flat rate mode respectively higher product rate per area; e.g. in the flat rate mode it is possible to increase the frequency to a continuous output of the product and to a higher or maximum output value) to ensure complete emptying of the tank. The maximum values are predefined values for the herbicide and the corn on the agricultural field (i.e. product rate that leads to a damage of corn and/or soil and/or environment).
The computing means may be completely or partly a part of the application device 10, or a distributed computing system and may comprise mobile devices communicatively coupled to the computing means.
In a second step 42, the location-specific sensor data may be analyzed with respect to at least one treatment indicator by the computing means.
In a third step 44, a treatment savings parameter for the treatment is provided. The treatment savings parameter characterizes the amount of treatment based on the location-specific sensor data in relation to an amount of treatment based on a reference treatment.
The treatment savings parameter can be advantageously used to support adapting product rate and/or the frequency based on the current position of the application device in the route through the agricultural field and the current amount of the product in the tank of the application device such that at the end of the route of the application device through the agricultural field a predetermined amount of the product is in the tank, preferably the predetermined amount at the end of the route is substantially zero. In particular it can be used to support the forecast calculation.
In one example, the treatment savings parameter is a comparison between a determined amount of treatment and a flat rate treatment, wherein the same amount of treatment is applied on the agricultural field. Additionally or alternatively, the reference treatment can also comprise historic data, in particular data from historic treatments.
In one exemplary embodiment, a comparison between the location-specific sensor data and a threshold is used to determine if the treatment component should be activated, for example switched between an on- and off-state. Alternatively or additionally, the strength of the activation and therefore the locally applied dosage can be controlled.
As an example, the number or density of weed present in the specific location of the agricultural field can be used. Alternatively or additionally, the number or density of cultivated crops present in the specific location of the agricultural field can be used. The threshold may be determined before the treatment based on previous available data and it may be adapted during the treatment.
The treatment savings parameter for a treatment can be defined in several ways, depending on the available data. The treatment savings parameter is a relation between data derived from in real-time acquired location-specific sensor data and reference treatment data.
In one exemplary embodiment, the treatment savings parameter can relate to a derived amount of treatment which is not to be applied, and the reference data can relate to the amount of treatment used during a flat rate treatment.
In another exemplary embodiment, the treatment savings parameter can relate to the not applied amount of treatment and the reference data can relate to the amount of treatment used during a flat rate treatment.
In
In the embodiment depicted in
Therefore treatment is performed in this example on the subareas Da, Db, Cc, Bd, Cd and Ce. No treatment is performed on the subareas Aa-Ca, Ab-Cb, Ac, Bc, Dc, Ad, Dd, Ae, Be and De. From the historic treatment data it is derived that treatment was done on all subareas, a flat treatment.
The treatment savings parameter can then be determined based on the number of non-treated subareas divided by the number of treated subareas derived from the historic treatment data in real-time. To illustrate the method, treatment is performed from rows D to A and over all columns a to e at the same time. So the treatment savings parameter could start to amount from 3/5=60% after treating row D, to 5/10=50% after treating rows D and C, to 9/15=60% after treating rows D to B and to 14/20=70% after treating rows D to A. Alternatively or additionally to an accumulated treatment savings parameter, a treatment savings parameter for each row can be determined in real-time. The treatment savings parameter for row D would be 3/5=60%, for row C 2/5=40%, for row B 4/5=80% and for row A 5/5=100%.
In the embodiment depicted in
The treatment savings parameter can then be determined for example based on the number of treatment component activations and the number of possible operations or the number of subareas, in particular from a log file generated by the application device and updated when activating, not activating and/or blocking the one or more treatment components of the application device. In this example the treatment savings parameter for row D′ could be derived in real time to 1-3/5=40%, for row C′ 1-3/5=40%, for row B′ 1-2/5=60% and for row A′ 1-5/5=100%. An accumulated treatment savings parameter for a treatment starting from row D′ to row A′ could the be derived to be 1-3/5=40% after treating row D′, 1-6/10=40% after treating rows D′ and C′, 1-8/15=46.67% after treating rows D′ to B′ and 1-13/20=70% after treating rows D′ to A′.
In the embodiment depicted in
In this example the treatment savings parameter for row D″ could be derived in real time to 1-(75%+75%+25%+50%+50%)/5=45%, for row C″ 1-(25%+25%+75%+100%+75%)/5=40%, for B″ 1-(0%+0%+50%+75%+0%)/5=75% and for A″ 1-(0%+50%+25%+50%+0%)/5=75%. An accumulated treatment savings parameter for a treatment starting from row D″ to row A″ could then be derived to be 45% after treating row D″, 42.5% after treating rows D″ and C″, 53.3% after treating rows D″ to B″ and 58.75% after treating rows D″ to A″.
In general, treatment savings parameter can alternatively or additionally be based on data from at least one of the following:
Additionally or alternatively, historic data can be used to compare the real-time treatment with a historic treatment or data from a treatment of another agricultural field can be used to compare with the actual treatment.
Data used for the treatment savings parameter can come from the processed real-time location-specific sensor data, such as from a determined location-specific amount of treatment or from control data, but also for example from machine data, external sources, such as external databases, or from other sensor devices, for example a tank sensor.
In a further embodiment the treatment savings parameter is stored on a storage device. This way applied maps can be recorded by storing the time, treatment savings parameter corresponding to such time, the position corresponding to such time and optionally the activation signal information coming from control data corresponding to such time. As a result, the data collected during operation can be stored and used after operation for further analysis.
Here the real or determined treatment may be recorded optionally together with the activation signal including the information on which treatment component was triggered when with which activation signal. In this way the treatment savings parameter can be provided for further use, for example for another treatment, another type of treatment or another application device as input for a treatment.
The displayed information may be updated in real-time or at a specific frequency, for example 1 Hz. Exemplarily, the treatment savings parameter 68 can be updated based on the provided treatment savings parameter or the information about the agricultural field 62 based on location data.
Additionally, the display output may be modified based on external input, especially on input from a human-machine interface, for example from an operator of the application device. For example, a treatment indicator or other performance parameter may be modified based on external input.
The treatment device 17 shown in
The spray nozzles 21 may be fixed or may be attached movable along the boom in regular or irregular intervals. Each spray nozzle 21 may arranged together with one or more, preferably separately, controllable valves 38 regulate fluid release from the spray nozzles 21 to the agricultural field 11.
