Description

[Technical field]

[0001] The present invention relates to a silage management method, a silage management system, and a silage management program, and can be suitably used, for example, in a silage management method, a silage management system, and a silage management program that use a horizontal silo such as a bunker silo. [Background technology]

[0002] Horizontal silos such as bunker silos are facilities for fermenting grass to produce silage, which is livestock feed. In relation to the above, Patent Document 1 (JP Patent Publication No. 09-000058) discloses a bunker silo. This bunker silo has a substantially rectangular floor surface and three side walls connected to the floor at positions corresponding to three of the four sides of the rectangle. While these three side walls are connected to each other, the position corresponding to the remaining one of the four sides of the rectangle is open, and a transport vehicle can enter from the outside from this position and carry grass into the inside of the bunker silo surrounded by the side walls.

[0003] Furthermore, if a horizontal silo such as a bunker silo has multiple compartments separated by side walls, different types of grass can be brought into each compartment. By blending multiple types of silage produced in this way in an appropriate combination and in an appropriate ratio, the quality of the feed can be stabilized. Silage produced in multiple horizontal silos can also be blended. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 09-000058 Summary of the Invention [Problem to be solved by the invention]

[0005] In order to blend silage appropriately, it is necessary to manage the silage for each horizontal silo. In other words, for the grass brought into each location in the horizontal silo, it is necessary to accurately record the grass species, the field where it was harvested, the date and time of harvest, the position in the horizontal silo where it was brought in, the date and time it was brought into the horizontal silo, the type of additives used to ferment the grass, etc. However, it is a cumbersome task for users to record such information on paper or to review it later.

[0006] In view of the above circumstances, an object of the present disclosure is to provide a silage management method, a silage management system, and a silage management program that can efficiently manage silage in a horizontal silo. Other objects and novel features will become apparent from the description of this specification and the accompanying drawings. [Means for solving the problem]

The field information identifying unit (614) identifies field information that identifies the field (2) based on the positioning information. The grass species information identifying unit (615) identifies grass species information that identifies the type of grass based on the field information. The delivery information identifying unit (616) identifies delivery information that identifies the horizontal silo (4), the delivery position of the grass in the horizontal silo (4), and the delivery time when the grass was delivered to the delivery position, based on the positioning information. The silage information management unit (615) manages silage information that links the field information, grass species information, and delivery information.

[0010] According to one embodiment, the silage management program is executed to realize the processing of the silage management device. This processing includes measuring the position of the transport vehicle (3) that transports the grass from the field (2) where the grass is harvested to the horizontal silo (4) where the grass is brought in at multiple times, and acquiring positioning information that associates the measured position with the measurement time (S102). This processing further includes specifying field information that identifies the field (2) based on the positioning information (S103), specifying grass species information that identifies the type of grass based on the field information (S104), and specifying delivery information (S105) that respectively identifies the horizontal silo (4), the delivery position in the horizontal silo (4) where the grass was brought in, and the delivery time when the grass was brought in to the delivery position, based on the positioning information. This process further includes managing silage information that links the field information, grass species information, and delivery information (S106). Effect of the Invention

[0034] An example of a configuration of a silage management method according to an embodiment will be described with reference to Fig. 5. In other words, an example of an operation of the silage management system 1 according to an embodiment will be described.

[0035] When the flowchart of FIG. 5 starts, step S101 is executed. In step S101, the arithmetic device 31 of the in-vehicle terminal 30 executes an in-vehicle terminal program to realize the processing of the vehicle information acquisition unit 311, and the vehicle information acquisition unit 311 acquires vehicle information of the transport vehicle 3. The vehicle information includes, for example, vehicle identification information that identifies the transport vehicle 3, vehicle type identification information that identifies the vehicle type of the transport vehicle 3, and loading amount information that indicates the loading amount of grass that the transport vehicle 3 can transport at one time. The vehicle information may be stored in advance in, for example, the storage device 32. Thereafter, the arithmetic device 31 of the in-vehicle terminal 30 further executes an in-vehicle terminal program to realize the processing of the communication unit 313, and the communication unit 313 controls the communication device 34 to transmit the vehicle information to the silage management device 6.

[0036] At this time, the calculation device 61 of the silage management device 6 executes the silage management program to realize the processing of the communication unit 612, and the communication unit 612 controls the communication device 63 to receive the vehicle information. After that, the calculation device 61 of the silage management device 6 further executes the silage management program to realize the processing of the vehicle information acquisition unit 611, and the vehicle information acquisition unit 611 acquires the vehicle information and stores it in the storage device 62.

[0037] After step S101, step S102 is executed. In step S102, the arithmetic device 31 of the on-board terminal 30 executes the on-board terminal program to realize the processing of the positioning unit 312, and the positioning unit 312 controls the positioning device 33 to acquire positioning information of the transport vehicle 3. More specifically, the positioning unit 312 acquires position information representing the position of the on-board terminal 30 based on a positioning signal received by the positioning device 33 from a GNSS positioning satellite or the like. Here, the position of the on-board terminal 30 is substantially the same as the position of the transport vehicle 3 on which the on-board terminal 30 is mounted. The positioning unit 312 acquires positioning information by measuring positions at multiple times and associating the measured positions with the measurement times at which the measurements were performed. Thereafter, the arithmetic device 31 of the on-board terminal 30 further executes the on-board terminal program to realize the processing of the communication unit 313, and the communication unit 313 controls the communication device 34 to transmit the positioning information to the silage management device 6.

[0038] At this time, the arithmetic device 61 of the silage management device 6 executes the silage management program to realize the processing of the communication unit 612, and the communication unit 612 controls the communication device 63 to receive the positioning information. After that, the arithmetic device 61 of the silage management device 6 further executes the silage management program to realize the processing of the positioning information acquisition unit 613, and the positioning information acquisition unit 613 acquires the positioning information and stores it in the storage device 62.

[0039] After step S102, step S103 is executed. In step S103, the arithmetic device 61 of the silage management device 6 executes the silage management program to realize the processing of the field information identifying unit 614, and the field information identifying unit 614 identifies the field information of the field 2. More specifically, the field information identifying unit 614 refers to the field database 622 to determine whether or not the position information of any of the fields included in the field database 622 is included in the positioning information. For example, when the distance from any of the position information included in the positioning information to the position information of any of the fields is shorter than a predetermined threshold, the field information identifying unit 614 determines that the position information of the field is included in the positioning information. When it is determined that the position information of any of the fields is included in the positioning information, the field information identifying unit 614 identifies the field located at the position indicated by this position information as the field 2 from which the transport vehicle 3 transported the pasture. Furthermore, the field information identifying unit 614 extracts the field information of the identified field 2 from the field database 622. In this way, the field information identifying unit 614 identifies the field information of the field 2.

[0040] After step S103, step S104 is executed. In step S104, the calculation device 61 of the silage management apparatus 6 executes a silage management program to realize processing of the grass species information identification unit 615, and the grass species information identification unit 615 identifies the grass species information of the grass transported by the transport vehicle 3. More specifically, the grass species information identification unit 615 extracts grass species information harvested in the field 2 from the field information of the field 2 extracted in step S103. In this way, the grass species information identification unit 615 identifies the grass species information of the grass.

[0041] After step S104, step S105 is executed. In step S105, the calculation device 61 of the silage management device 6 executes the silage management program to realize the processing of the delivery information identification unit 616, and the delivery information identification unit 616 identifies delivery information related to the delivery of the grass to the bunker silo 4 by the transport vehicle 3. The delivery information includes, for example, information identifying the bunker silo 4 to which the grass was delivered, information identifying the delivery position in the bunker silo 4 to which the grass was delivered, information identifying the delivery time at which the grass was delivered to this delivery position, and delivery amount information indicating the delivery amount of the grass delivered to this delivery position. The delivery amount of the grass may be estimated based on the load capacity of the transport vehicle 3, and for example, the delivery amount may be the product of the load capacity multiplied by a predetermined ratio. The delivery information may further include additive information indicating the type of additive used for the delivered grass.

[0042] A method for the delivery information identification unit 616 to identify information identifying the bunker silo 4 into which the grass has been delivered will be described. The delivery information identification unit 616 refers to the silo database 623 and determines whether or not the position information of any of the bunker silos 4 included in the silo database 623 is included in the positioning information. For example, when the distance from the positioning position represented by any of the position information included in the positioning information to the bunker silo position represented by the position information of any of the bunker silos 4 is shorter than a predetermined threshold, the delivery information identification unit 616 determines that the position information of the bunker silo 4 is included in the positioning information. If it is determined that the position information of any of the bunker silos is included in the positioning information, the delivery information identification unit 616 identifies the bunker silo 4 at the position represented by this position information as the bunker silo 4 into which the transport vehicle 3 has delivered the grass. In this way, the delivery information identification unit 616 identifies information identifying the bunker silo 4 into which the grass has been delivered.

[0043] The method by which the delivery information identification unit 616 identifies information that identifies the delivery position in the bunker silo 4 where the grass was delivered will be described. The delivery information identification unit 616 extracts position information that indicates the position inside the bunker silo 4 from the position information included in the positioning information. The delivery information identification unit 616 further extracts stop position information that indicates the position where the transport vehicle 3 stopped from the extracted position information. In one embodiment, it is assumed that the grass was unloaded at the position where the transport vehicle 3 stopped inside the bunker silo 4, and the position indicated by the extracted stop position information is identified as the delivery position in the bunker silo 4 where the grass was delivered. Inside the bunker silo 4, grass may be delivered to multiple delivery positions, and the grass delivered to these multiple delivery positions may be different from the harvested field 2 or different types. However, it is preferable that the grass delivered to the same delivery position multiple times is the same type of grass harvested in the same field 2.

[0044] A method for the delivery information identification unit 616 to identify information identifying the delivery time when the grass was delivered to the delivery position will be described. When the delivery information identification unit 616 extracts stop position information representing a position identified as the delivery position, it further extracts information representing a measurement time associated with this stop position information from the positioning information. This measurement time is called the stop time, and the information representing this measurement time is called the stop time information. In one embodiment, the stop time extracted in this manner is identified as the delivery time when the transport vehicle 3 unloaded the grass inside the bunker silo 4.

[0045] A method will be described in which the delivery information identification unit 616 identifies additive information indicating the types of additives used in the bunker silo 4. After identifying information for identifying the bunker silo 4, the delivery information identification unit 616 refers to the silo database 623 and extracts additive information on the additives used in the identified bunker silo 4. Note that an example of an additive that ferments grass to produce silage is lactic acid bacteria.

[0046] The operation of the transport vehicle 3 to deliver different kinds of grass to a plurality of delivery positions inside the bunker silo 4 will be described in detail after the description of the flow chart in FIG.

[0047] After step S105, step S106 is executed. In step S106, the calculation device 61 of the silage management device 6 executes a silage management program to realize the processing of the silage information management unit 617, and the silage information management unit 617 manages the silage information. The silage information includes the field information identified in step S103, the grass species information identified in step S104, and the carrying-in information identified in step S105, all linked together. The silage information management unit 617 stores the silage information configured in this way in the storage device 62.

[0048] After step S106, step S107 is executed. Step S107 may be executed after the grass is sufficiently fermented. In step S107, the calculation device 61 of the silage management device 6 executes a silage management program to realize the processing of the silage information management unit 617, and the silage information management unit 617 outputs a combination of grasses for producing silage. More specifically, after the multiple grasses brought into the multiple carrying-in positions inside the bunker silo 4 are sufficiently fermented, some or all of the multiple grasses are combined and blended in a predetermined ratio to produce silage with stable quality. The silage information management unit 617 calculates the combination and ratio of grasses for producing silage with a desired quality based on the farm field information, grass species information, and carrying-in information linked as silage information in step S106, and stores the combination and ratio in the storage device 62.

[0049] Thereafter, the arithmetic device 61 of the silage management device 6 executes the silage management program to realize the processing of the communication unit 612, and the communication unit 612 outputs blend information indicating the combination and ratio of grasses and transmits it to the external terminal 7. At this time, the arithmetic device 71 of the external terminal 7 executes the external terminal program to realize the processing of the communication unit 711, and the communication unit 711 receives the blend information and stores it in the storage device 72. Thereafter, the arithmetic device 71 of the external terminal 7 executes the external terminal program to realize the processing of the input / output unit 712, and the input / output unit 712 controls the input / output device 74 to output the blend information. As an example, the input / output device 74 is a touch panel device that displays the blend information.

[0050] After step S107, step S108 is executed. In step S108, the user blends the grass according to the combination and ratio calculated in step S107. In this way, silage of desired quality can be stably produced using multiple grasses brought into multiple delivery positions of the bunker silo 4. The user may blend the grasses and produce silage at a TMR (Total Mixed Ration) center.

[0051] After step S108, the flow chart of Fig. 5 ends. After step S108, the process of the flow chart of Fig. 5 may return to step S101.

[0052] As a modification of the silage management method described above, after step S106, the process of the flowchart in Fig. 5 may return to step S101. In this way, the process in which the transport vehicle 3 transports the grass from the farm field 2 to the bunker silo 4 multiple times may be managed in an integrated manner.

[0053] As a supplementary explanation of step S105 in the flowchart of FIG. 5 described above, a method in which the transport vehicle 3 delivers a plurality of pieces of grass to a plurality of delivery positions in the bunker silo 4 will be described with reference to FIGS. 6A to 6E.

[0054] As shown in FIG. 6A, the bunker silo 4 may have a plurality of sections 21A, 21B separated by a wall 20. The transport vehicle 3 moves backward along the travel path 8A from the entrance of the section 21A of the bunker silo 4 to a predetermined loading area 9A, stops, and unloads the loaded grass by tilting the loading platform. In this way, the grass is loaded into the loading area 9A. At this time, the loading position that is measured may be specified as, for example, an end of the travel path 8A that contacts the loading area 9A or a position in the vicinity thereof. Note that when unloading the grass from the loading platform, the transport vehicle 3 may move in the forward and backward directions to perform this work smoothly. Therefore, the loading position may be specified on the condition that the travel speed of the transport vehicle 3 is slower than a predetermined threshold value. After unloading the grass, the transport vehicle 3 may return to the field 2 to transport more grass.

[0055] As shown in FIG. 6B, the transport vehicle 3 again moves backward along the travel path 8B from the entrance / exit of the section 21A of the bunker silo 4, and this time unloads the grass into a predetermined loading area 9B. Here, the loading area 9B is an area obtained by extending the loading area 9A where the grass was previously unloaded in the longitudinal direction of the section 21A, and may include the loading area 9A. Since the grass brought in this time and the grass brought in last time are mixed in the loading area 9B, it is preferable that they are the same grass species harvested in the same field 2. However, the transport vehicle 3 that brought in this time and the transport vehicle 3 that brought in last time do not necessarily have to be the same transport vehicle 3. After unloading the grass, the transport vehicle 3 may return to the field 2 to transport more grass.

[0056] 6C, as the transport vehicle 3 repeatedly brings in grass, the area into which the same type of grass has been brought in may be expanded in the width direction of the section 21A, such as a bringing-in area 9C. At this time, the travel path 8C of the transport vehicle 3 may be shifted in the width direction of the section 21A compared to the travel paths 8A and 8B.

[0057] As shown in Fig. 6D, grass harvested in a field 2 other than the carrying-in area 9C or a different type of grass from the carrying-in area 9C may be carried into a carrying-in area 10A other than the carrying-in area 9C in the same section 21A of the same bunker silo 4. In this case, in order to prevent the grass in the carrying-in areas 9C and 10A from being mixed, the transport vehicle 3 moves from an entrance / exit of the section 21A away from the carrying-in area 9C along the travel path 8D away from the carrying-in area 9C to the carrying-in area 10A and unloads the grass.

[0058] 6E, when the transport vehicle 3 repeatedly brings in different grass, the area into which the different grass has been brought in may be expanded in the longitudinal and width directions of the section 21A, like the carrying area 10B. At this time, the travel path 8E of the transport vehicle 3 may be shifted in the width direction of the section 21A compared to the travel path 8D.

[0059] By carrying in pasture in this manner, multiple types of pasture can be carried in to the same section 21A of the same bunker silo 4. As described above, the transport vehicle 3 automatically records the position and time at which the pasture is unloaded, so it is possible to automatically manage which portion of the pasture carried in to the same section 21A is which type of pasture and which field 2 it was harvested in.

[0060] Additives such as lactic acid bacteria are added to the brought-in pasture, which is then covered with plastic sheeting and weights are placed on it to remove the air, promoting anaerobic fermentation.

[0061] As described above, according to the silage management method, silage management system 1, and silage management program of one embodiment, information such as the field 2 where the grass was harvested, the type of grass, the bunker silo 4 where the grass was brought in and the location of the area inside it, the time the grass was brought in, additives added to the grass, etc. are automatically acquired and then linked for management. In this way, management for producing silage of stable quality can be efficiently performed.

[0062] Although the invention made by the inventor has been specifically described based on the embodiment, the present invention is not limited to the embodiment, and it goes without saying that various modifications can be made without departing from the gist of the invention. Furthermore, the respective features described in the embodiment can be freely combined within the scope of technical compatibility. [Explanation of symbols]
