Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to agricultural implements, and, more particularly, to agricultural implements utilizing precision farming techniques. 
         [0003]    2. Description of the Related Art 
         [0004]    Agricultural planters are commonly used implements to plant seeds in soil. An agricultural planter can include a chassis that carries one or more storage tanks carrying seed, and chemical applications that are to be applied to the field during the planting operation, a hitch mechanism that attaches to a tractor or other implement pulled by a tractor, and a tool bar that row units can be connected to so they are carried by the chassis. The planter can also include a pneumatic system carried by the chassis that supplies pressurized air to transport the seeds or other particulate from the storage tanks to the row units. 
         [0005]    Each row unit of the agricultural planter places seeds in the field. Typically, the row units are laterally arranged along a length of the tool bar so that as the planter is pulled across the field, each row unit plants seeds at predefined intervals along the path it is pulled across. To plant seeds, the row units perform four main operations as they are pulled: opening a trench in the soil; placing a seed into the formed trench at appropriate intervals; closing the formed trench to put soil on top of the placed seed; and packing soil on top of the seed to provide desirable soil contact with the placed seed. To open a trench in the soil, a furrowing disc system, which may include an opening disc, cuts into the soil and rotates, dislocating soil as it rotates to form the trench. Once the trench is open, a seed is placed in the trench by a metering device which receives seeds from the main storage tank(s) or a row unit storage tank and typically utilizes a combination of differential air pressure, to select the seed, and gravity to place the seed in the trench at predefined intervals along the pulled path so that adjacent seeds in the row are not too close to one another. One or more closing discs carried behind the furrowing disc are pressed into the soil and also rotate as the planter is pulled to replace soil dislocated by the furrowing disc in the trench or dislocate adjacent soil into the trench to cover the seed placed in the trench with soil. Finally, a pressing wheel carried behind the closing disc(s) exerts pressure on the soil covering the seed to press the soil down onto the seed and provide good soil contact with the seed. By having multiple row units working in unison as the planter is pulled across a field, many seeds can be effectively planted in an efficient manner. 
         [0006]    Precision farming systems are widely used with agricultural implements, including planters. In general, a precision farming system or technique uses geospatial data for a given geographic region (e.g., agricultural field, strip or other area) and carries out one or more specified tasks based at least in part on the geospatial data. The geospatial data is usually derived from a global positioning system (GPS) sensor located onboard the vehicle, and the position of the vehicle at least in part triggers various actions or tasks to occur. For example, agricultural vehicles such as planters, sprayers, fertilizer spreaders, etc, can carry out variable rate application of a product to the field based on the geospatial data. The fields can be mapped for soil type, fertility or pH levels, etc, and the GPS data for the current position of the vehicle can trigger different application rates as the vehicle traverses across the field. 
         [0007]    What is needed is an improved precision farming arrangement that allows product to be efficiently and cost effectively applied to a field. 
       SUMMARY OF THE INVENTION 
       [0008]    The present invention allows data representing at least one attribute associated with seed to be transferred to a remote computer, edited by a user, and uploaded to a precision farming system for use during a farming operation. 
         [0009]    The invention in one form is directed to a method of operating an agricultural implement in a geographic area using data representing at least one attribute associated with seed. The method includes the steps of: 
         [0010]    transferring data including at least one attribute associated with seed to a remote computer which is located remote from the geographic area; 
         [0011]    editing the data at the remote computer; 
         [0012]    uploading the analyzed data to an electrical processing circuit associated with the implement; and 
         [0013]    operating the implement under control of the electrical processing circuit within the geographic area, using the uploaded data. 
         [0014]    An advantage of the present invention is that data corresponding to a particular seed is uploaded to a remote computer where it can be edited by a user offline while not farming, then uploaded into the precision farming system associated with an implement and used during a farming operation. 
         [0015]    Another advantage is that the seed related data can be carried over and used from one farming operation to another, such as planting and spraying.

       DETAILED DESCRIPTION OF THE INVENTION 
       [0021]    Referring now to the drawings, and more particularly to  FIG. 1 , there is shown an embodiment of an agricultural implement in the form of a planter  10 , which generally includes a chassis  11  forming a support structure for components of the planter  10 . The planter  10  can include a hitch assembly  12  at a front of the planter  10  connected to a tool bar  14  to form the chassis  11 , main wheels  16  carried by the chassis  11  near a rear of the planter  10 , one or more storage tanks  18 ,  20 ,  22  carried by the chassis  11  that can be filled with seed or other agriculture material, and a plurality of row units  24  connected to the tool bar  14  and arranged laterally across a length of the tool bar  14  so that they are carried by the chassis. The hitch assembly  12  can include a hitch  26  configured to be connected to a two vehicle in the form of a tractor  13  (shown partially) or other agricultural implement (not shown) so that the planter  10  can be pulled in a forward direction of travel. The hitch  26  can be integrally formed with or connected to a hitch bar  94  that is connected to the tool bar  14  by bracing bars  30  and one or more cylinders  32 . As can be seen throughout  FIG. 1 , the planter  10  can also have various hydraulic, pneumatic, and electrical lines (unnumbered) throughout to support various cylinders and systems that are included on the planter  10 , such as a pneumatic system  34  connected to the tool bar  16  and an electric generator  36  also connected to the tool bar  16 . A marking device  38  can be connected to each lateral end of the tool bar  14  and extendable so that a marking disc  40  of the marking device  38  can create a line in the soil as the planter  10  is pulled that helps a user in positioning the planter  10  to create subsequent rows. A stair assembly  42  can be mounted to the back of the planter  10  to allow an operator to access the storage tanks  20  and  22 . Various actuators (not shown) onboard the planter  10  (or other implement, such as a sprayer, etc.) are used to apply the product at known application rates under control of electronic controller  86 . 
         [0022]    Referring now to  FIG. 2 , there is shown a schematic illustration of the agricultural planter  10  for seeding within a geographic area, such as all or a portion of field  80  shown in  FIG. 1 . According to an aspect of the present invention, agricultural seed or seed applicant information can be stored, edited and utilized throughout the planting, spraying and/or other farming operations. To that end, seed vendor data (e.g., from a seed vendor computer  100 ) representing one or more attributes of the seed can be transferred to a remote computer  102 , such as over an internet connection  104 , edited by a user at the remote computer  102 , and then uploaded to an electrical processing circuit  86  associated with the planter  10  for subsequent use during farming operations. The seed vendor data can include data representing an attribute of the seed purchased by the user/farmer/agronomist. For example, the seed vendor data can include data representing a manufacturer, product number, suggested population rate, total number of seeds per bag, active ingredients within the bag, inert ingredients within the bag, etc. Other types of data representing attributes associated with the seed may also be possible. 
         [0023]    Located within operator cab  94  are an electrical processing circuit  86 , a visual display  88  and a memory  90 . Visual display  88  is coupled with electrical processing circuit  86  and provides a visual display to an operator located within operator cab  94 . Visual display  88  can display a number of different types of visual information, including seed vendor data associated with the seed. Visual display  88  may be any suitable type of display, such as an LED display, LCD display, etc. 
         [0024]    Memory  90  likewise is coupled with electronic controller  86  and may be any suitable type of memory, such as a static or dynamic memory. Memory  90  may include any type of relevant data, including precision farming data which may be generated by the operator or obtained from a number of different commercial sources (represented by the dashed box  92 ). Such data can be uploaded to memory  90  using any suitable technique, such as a direct wired or wireless upload, wireless Internet upload, satellite upload, etc. The precision farming data may be of different data types, such as a topographical map of the geographic area; at least one soil type associated with the geographic area; at least one application rate of the active ingredient associated with the geographic area; at least one fertility level of soil associated with the geographic area; and at least one pH level of soil associated with the geographic area. For purposes of illustration, a portion of a topographical map for a field  80 , including soil types  80 A,  80 B and  80 C is shown in  FIG. 1 . 
         [0025]    Electrical processing circuit  86  is shown as a digital electronic controller in  FIG. 2 , but could also be configured as an analog type processing circuit. Electronic controller  86  receives precision farming data from memory  90  associated with the geographic area represented by field  80 . Electronic controller  86  matches the seed vendor data with the precision farming data to establish one or more seeding or application rates over at least a portion of field  80 . For example, when planting, the application rate can be a population rate of the seed within the different soil types  80 A,  80 B and  80 C within the field  80 . If the seed information is carried over to subsequent farming operations such as spraying, the application rate can be an application rate of a herbicide for different soil types  80 A,  80 B and  80 C within field  80 . 
         [0026]    As shown in  FIG. 1 , a field  80  can include multiple soil types  80 A,  80 B and  80 C. By automatically matching the seed vendor data with the precision farming data, electronic controller  86  can vary the application rate from one soil type to another as the planter  10  (or sprayer, etc.) moves across field  80 . An operator can optionally be prompted on visual display  88  to accept the application rates based on the matched data, or can manually enter another application rate(s) by overriding the application rates based on the match data. 
         [0027]    More specifically, and referring now to  FIG. 3 , the seed vendor data can be transferred to the remote computer stored in the memory  90  in a number of ways. For example, a potential purchaser of seed can create an online account with the seed vendor (e.g., seed company or seed dealer, block  110 ). Upon completion of a seed purchase (block  112 ), the seed vendor data can be transferred to the remote computer  102  via the internet using desktop software on the remote computer  102  (block  114 ). The user/farmer/agronomist can then edit the seed vendor data offline from the farming operation (block  116 ). For example, the user/farmer/agronomist can view, manipulate, sort, select, calculate and/or store the seed vendor data using the remote computer. 
         [0028]    At decision block  118 , a determination is made as to whether the edited seed vendor data should be pushed to a vehicle or fleet of vehicles associated with a farming operation. If the answer is NO, then no action occurs (block  120 ). On the other hand, if the answer is YES, then a determination is made as to whether telematics are available, which typically means that a wireless connection of some type is available (e.g., wireless internet, mobile phone connection, etc; block  122 ). If telematics are available, then the edited seed vendor data is pushed to the vehicle or fleet of vehicles (block  124 ), and the operator can use the seed vendor data during the farming operation (block  126 ). 
         [0029]    On the other hand, if telematics are not available, then an external memory device (such as a flash drive, SD card, etc.) can be used to upload the edited seed vendor data to the precision farming system associated with the farming operation (decision block  128 ). The edited seed vendor data can be saved to the external memory device from the remote computer  102  (block  130 ), and subsequently uploaded to the precision farming system (block  132 ). The operator can then use the seed vendor data during the farming operation (blocks  126  and  128 ). 
         [0030]    The edited seed vendor data can be uploaded and displayed on the display  88  for viewing by an operator. Using initial volumes of product, known application rates, etc. the operator can be alerted when product becomes low in one or more product containers (such as hoppers, bulk tanks, etc.) 
         [0031]    In the embodiment described above, the data representing at least one seed attribute is transmitted to the remote computer  102  from a seed vendor computer  100 , such as through an internet connection  104 . However, it is also possible to transmit the data representing at least one seed attribute to the remote computer  102  in other ways. For example, an ID tag  82  can be attached or otherwise affixed to a container of seed  80  and automatically read using an appropriate reader  84  ( FIG. 2 ). The container of seed  80  is assumed be a bag of seed in the illustrated embodiment, but could be another suitable type of container, such as a bulk seed hopper or the like. 
         [0032]    ID tag  82  is shown positioned toward an end of the bag of seed  80  but can be positioned at any suitable location allowing automated reading thereof. ID tag  82  can be any type of tag which can be read in an automated manner, such as a radio frequency identification (RFID) tag, barcode, Quick Response (QR) code, etc. In the illustrated embodiment, ID tag  82  is assumed to be in the form of a tag with a barcode. 
         [0033]    Barcodes are well known for many different purposes, and basically include a number of parallel bars of varying thickness, providing a 1 dimensional code when read by a suitable reader. QR codes are similar to bar codes, but provide a 2 dimensional code when read by a suitable reader. Radio frequency identification (RFID) tags are well known throughout industry, and are being increasingly utilized for supply chain management, inventory management, and logistic control. These tags can be written to and read from a handheld transceiver (referred to as an RFID reader) or fixed portal. For example, an RFID tag can be placed upon a shipping container and contain data corresponding to the contents of the shipping container. The RFID tag can be read using a handheld reader or a portal reader, and the data offloaded from the reader to a computer for processing. 
         [0034]    ID tag  82  includes data representing an attribute of the seed within the bag of seed  80 . For example, ID tag  82  can include data representing a manufacturer, product number, suggested population rate, total number of seeds per bag, active ingredients within the bag, inert ingredients within the bag, etc. Other types of data representing attributes associated with the seed may also be possible. 
         [0035]    Electronic controller  86  can be coupled with a reader  84 , either wired or wireless, and receives output signals from reader  84  representing data associated with the seed within the bag of seed  80 . Electronic controller  86  controls operation of reader  84  to read ID tag  82  either automatically or on command. For manual or “on command” reading of ID tag  82 , and operator within operator cab  94  can manually depress a switch or button, such as a virtual button  96  on visual display  88 . A corresponding output signal is provided from visual display  88  to electronic controller  86 , which in turn effects the read operation of ID tag  82  using reader  84 . 
         [0036]    Reader  84  can be a barcode reader if ID tag  82  is configured as a barcode. For some applications, reader  84  can be a handheld reader providing a wired or wireless output signal to the electrical processing circuit  86 . In the event that the ID tag  82  is an RFID tag, then the reader  84  can be handheld, or carried directly or indirectly by chassis  11  and positioned at a suitable location allowing automated reading of ID tag  82 . For example, reader  84  can be in the form of an RFID portal reader which is positioned at a suitable location onboard the planter  10 . 
         [0037]    While this invention has been described with respect to at least one embodiment, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within the limits of the appended claims.
