In operation, an operator positions Applicants' vehicle 300, or Applicants' trailer 305, adjacent to a designated feeding site. In certain embodiments, the operator signals controller 400 to begin delivery of a pre-set feed formulation to the selected feed bunk by activating a switch/touch screen/icon disposed on external controller 460 (FIG. 3C). In certain embodiments, controller 400 verifies using UPS module 430 and the feeding site location recited in database 426. UPS module 430, using optional antenna 432, determines the actual location of vehicle 300 and compares that actual location to the location for the selected feed bunk recited in database 426. In certain embodiments, controller 400 verifies the formulation using RFID module 440, wherein module 440 emits an interrogating signal and receives using antenna 442 a response signal identifying the adjacent feed bunk.
In certain embodiments, the method compares the actual feeding site location with the designated feeding site location recited in database 426. If the actual feeding site location differs from the designated feeding site location, the method generates a Location Alert. The Location Alert is added to database 426. In certain embodiments, controller 400 provides the Location Alert to external controller 460, and external controller 460 emits an audible alert and/or visually displays an alert message. In certain embodiments, the Location Alert is provided wirelessly to a central feed lot server using WI-FI module 450 and optional antenna 452, and/or to a portable feed bin display device using RFID module 440.
In the illustrated embodiment of FIG. 5, database 426 comprises (N) formulations. Referring now to FIGS. 2, 4, and 5, in the illustrated embodiment of FIG. 5, database 426 recites that a pre-set quantity of 1000 pounds of feed 150 are targeted for delivery to the North Feed Blunk. Database 426 further recites that 950 pounds were actually delivered to the North Feed Bunk. In certain embodiments of Applicants' apparatus and method, measurement device 252 determines the amount of base feed 150 delivered at designated location.
Processor 410 enters that actual delivered amount into database 426. In certain embodiments, the actual weight of feed delivered is wirelessly provided to a central feed lot server using WI-FI module 450 and optional antenna 452, and/or to a portable feed bin display device using RFID module 440.
Further in the illustrated embodiment database 426 in FIG. 5, the nominal delivery window for delivery of base feed to the North Feed Bunk is +/− ten percent (10%) Because the actual amount delivered, i.e. 950 pounds, is within the pre-determined nominal window of 900 pounds to 1100 pounds, no alert was generated with respect to the amount of base feed delivered to the North Feed Bunk.
Further in the illustrated embodiment database 426 in FIG. 5, Additive A is to be added to the base feed to give a loading of 5 weight percent. In certain embodiments, controller 400 determines the weight of Additive A to be added to the base feed using database 426. Controller 400 opens valve 274, thereby causing Additive A to flow from container 272, through valve 274, through conduit 276, and into the mixing assembly 210, or a portable feed bin. Measurement device 254 determines the actual amount of Additive A added to the base feed delivered to the North Feed Bunk, and provides that weight to controller 400. In certain embodiments, the actual weight of Additive A added is wirelessly provided to a central feed lot server using WI-FI module 450 and optional antenna 452, and/or to a portable feed bin display device using RFID module 440.
In certain embodiments, controller 400 calculates a weight percent loading of Additive A in the base feed using the weights provided by measurement devices 252 and 254. In certain embodiments, controller 400 then inserts the actual weight percent of Additive A in the base feed into database 426. In certain embodiments, controller 400 further determines if the actual loading of Additive A is within the nominal window for Additive A.
Similarly, controller 400 calculates a weight percent loading of Additive B in the base feed using the weights provided by measurement devices 254 and 256, and a weight percent loading of Additive C in the base feed using the weights provided by measurement devices 256 and 258.
The nominal delivery window for Additive A at the North Feed Bunk is +/− ten percent (10%). Because the actual 3 weight percent loading of Additive A is outside the pre-determined nominal window of 4.5 weight percent to 5.5 weight percent, in certain embodiments, controller 400 generates an Additive A Alert with respect to the amount of added to the base feed delivered to the North Feed Bunk. The Additive A Alert is added to database 426. In certain embodiments, controller 400 provides the Additive A Alert to external controller 460, and external controller 460 emits an audible alert and/or visually displays an alert message. In certain embodiments, the Additive A Alert is provided wirelessly to a central feed lot server using WI-FI module 450 and optional antenna 452, and/or to a portable feed bin display device using RFID module 440.
Controller 400 similarly determines the loadings of additional additives, such as for example Additive B and/or Additive C, using database 426, and opens the one or more corresponding valves, such as valves 284 and/or 294. Weigh cells 256 and/or 258 determine the actual weights of Additives B and C, respectively, added to the feed formulation, and provide those actual weights to controller 400. Controller 400 then calculates the actual weight percent loadings of Additives B and/or C, determines if the actual weight percent loadings fall within pre-set nominal windows, and optionally generates, records, and provides an alert for Additive B and/or Additive C if the actual loadings are not within the designated preset nominal windows. In certain embodiments, the Additive B Alert and/or Additive C Alert is provided wirelessly to a central feed lot server using WI-FI module 450 and optional antenna 452, and/or to a portable feed bin display device using RFID module 440.
In certain embodiments, instructions, such as instructions 424 (FIG. 4) residing in computer readable medium 420 (FIG. 4), are executed by a processor, such as processor 410 (FIG. 4), to prepare and dispense a designated feed composition at a designated feeding site using Applicants' portable feed preparation apparatus.
While the preferred embodiments of the present invention have been illustrated in detail, it should be apparent that modifications and adaptations to those embodiments may occur to one skilled in the art without departing from the scope of the present invention.
