Description

[Technical Field]

[0001] The present invention relates to a work plan transfer method, a work plan transfer system, and a work plan transfer program, which can be suitably used, for example, when transferring information representing a plan of agricultural work to be performed by a work device in a field from an external device to the work device. [Background technology]

[0002] Patent Document 1 (Japanese Patent Publication No. 6591496) discloses a work support system that supports work performed using agricultural machinery and other working machines. This work support system includes a fixed communication device mounted on the agricultural machine and connectable to a server, and a mobile communication device provided separately from the agricultural machine and connectable to the server. The agricultural machine performs work based on setting data. The setting data includes machine information for identifying the agricultural machine and setting values ​​for the agricultural machine. When the agricultural machine spreads fertilizer, the setting data includes information indicating the amount of fertilizer to be spread per unit time or per unit area.

[0003] As an example of Patent Document 1, the setting data may be generated by a mobile communication device, transmitted to a server, and then transmitted from the server to the agricultural machine. However, communication from the server to the agricultural machine may be difficult due to reasons such as a poor wireless communication environment in the field where the agricultural machine is working. Therefore, as another example of Patent Document 1, the setting data is generated by the server and transmitted to the mobile communication device, and then the state of the agricultural machine is confirmed before being transmitted from the mobile communication device to the agricultural machine.

[0004] [Patent Document 1] Patent No. 6591496 Summary of the Invention [Problem to be solved by the invention]

[0005] Thus, in Patent Document 1, the convenience of work is improved by providing setting data from a server to an agricultural machine, but there are many fields in mountainous areas and the like with poor wireless communication environments, and it may be difficult or impossible for the agricultural machine to acquire the setting data in the field where work is being performed. Furthermore, if, in order to alleviate such inconvenience, a mobile communication device that has acquired the setting data in advance in a location other than the field with a good wireless communication environment is used, the process of transferring the setting data to the agricultural machine becomes complicated.

[0006] In consideration of the above circumstances, an object of the present disclosure is to provide a work plan transfer method, a work plan transfer system, and a work plan transfer program for efficiently transferring information representing a work plan for a work device to execute a work to an on-board terminal that controls the work device.

[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A work plan transfer method, a work plan transfer system, and a work plan transfer program according to the present disclosure will be described below with reference to the accompanying drawings.

[0014] (First embodiment) As shown in Fig. 1, the work plan transfer system according to one embodiment includes a server 4, a user terminal 5, a first onboard terminal 20A, and a second onboard terminal 20B. Hereinafter, when there is no need to distinguish between the onboard terminals 20A and 20B, they may be collectively referred to as onboard terminals 20. The server 4, the user terminal 5, and the onboard terminal 20 may communicate with each other via wired and / or wireless communication via a network 3. Furthermore, communication between the user terminal 5 and the onboard terminal 20 may be performed by direct wireless communication without using the network 3.

[0015] The on-board terminal 20 is mounted on the work device 2. The work device 2 moves on the ground and performs agricultural work such as fertilizing (spreading fertilizer) and pest control (spraying pesticides) on a field 9. As an example, the work device 2 may be a broadcaster dedicated to fertilizing or a sprayer dedicated to pest control, or may be a tractor that pulls a work device that performs fertilizing, pest control, etc.

[0016] The onboard terminal 20 controls the work device 2 to perform work such as fertilization and pest control according to a predetermined work plan. The work plan may include field information that identifies the field 9 on which the work is to be performed, onboard terminal information that identifies the onboard terminal 20 that controls the work device 2 that is performing the work, a spray amount map that individually sets the amount of a spray material, such as fertilizer or pesticide, to be sprayed in each of a plurality of areas that are virtually divided into the field 9, and spray material information that identifies the spray material. The onboard terminal 20 controls the work device 2 to spray the amount of the material set in the spray amount map in each of the plurality of areas. The onboard terminal 20 may determine which area of ​​the field 9 the current position of the work device 2 is in by measuring the positions of each of a plurality of points that the work device 2 passes through while performing work in the field 9. The position may be measured using a Global Navigation Satellite System (GNSS) or a quantum compass that does not require an external auxiliary system such as an artificial satellite.

[0017] The server 4 transmits work plan information representing a work plan prepared in advance to the user terminal 5. However, as will be described later, this work plan may not necessarily match the work plan used by the onboard terminal 20 to control the maintenance device 2. For the sake of distinction, the work plan prepared in the server 4 is referred to as a proposed work plan, and the work plan used by the onboard terminal 20 to control the maintenance device 2 is referred to as a determined work plan.

[0018] The user terminal 5 may include a smartphone, tablet terminal, personal computer, or the like having communication, display, and input functions. The user terminal 5 may acquire proposed work plan information representing a proposed work plan from the server 4 and transfer the proposed work plan information to the on-board terminal 20. The user terminal 5 may also store work plan information previously transferred to the on-board terminal 20 as current work plan information. In this case, the user terminal 5 may determine one of the proposed work plan newly acquired from the server 4, the current work plan represented by the current work plan information already stored, or the integrated work plan obtained by integrating the proposed work plan and the current work plan as a determined work plan, and transfer determined work plan information representing the determined work plan to the on-board terminal 20. The determined work plan may be determined by a user of the user terminal 5 operating the user terminal 5.

[0019] 2, the server 4 according to one embodiment may be configured as a so-called computer. In the example of FIG. 2, the server 4 includes a bus 41, a computing device 42, a storage device 43, a communication device 44, and an input / output device 45. The bus 41 may be configured to realize communication between the computing device 42, the storage device 43, the communication device 44, and the input / output device 45.

[0020] The arithmetic device 42 executes a server program included in a work plan transfer program according to one embodiment, thereby realizing the processing of a work plan information transmission unit 421. The work plan information transmission unit 421 is a virtual functional block that executes processing realized in cooperation with the arithmetic device 42 and the storage device 43. The work plan information transmission unit 421 transmits work plan information to the user terminal 5 in response to a request from the user terminal 5.

[0021] The storage device 43 includes a program storage unit 431 and a data storage unit 432. The server program as part of the work plan transfer program may be read from an external recording medium 430 and stored in the program storage unit 431. The recording medium 430 may be a non-transitory and tangible medium. The data storage unit 432 may store work plan information representing a proposed work plan prepared in advance.

[0022] The communication device 44 communicates with external devices including the on-board terminal 20 and / or the user terminal 5 by wireless communication and / or wired communication via the network 3. A server program as part of the work plan transfer program may be received from the outside by the communication device 44 and stored in the program storage unit 431.

[0023] The input / output device 45 outputs information to the user and accepts operations input by the user. As an example, the input / output device 45 includes a display device that outputs images, a keyboard and / or a mouse that accepts input, etc.

[0024] 3, a user terminal 5 according to one embodiment may be configured as a so-called computer, similar to the case of the server 4 in FIG. 2. In the example of FIG. 3, the user terminal 5 includes a bus 51, a computing device 52, a storage device 53, a communication device 54, and an input / output device 55. The bus 51 may be configured to realize communication between the computing device 52, the storage device 53, the communication device 54, and the input / output device 55.

[0025] The arithmetic device 52 executes a user terminal program included in a work plan transfer program according to one embodiment, thereby realizing the processing of each of a work plan information acquisition unit 521, an identification information acquisition unit 522, and a work plan information transmission unit 524. The work plan information acquisition unit 521 requests and acquires work plan information from the server 4. The identification information acquisition unit 522 requests and acquires identification information from the onboard terminal 20. The work plan information transmission unit 524 transmits proposed work plan information representing a proposed work plan to the onboard terminal 20.

[0026] The storage device 53 includes a program storage unit 531 and a data storage unit 532. A user terminal program as part of the work plan transfer program may be read from an external recording medium 530 and stored in the program storage unit 531. The recording medium 530 may be a non-transitory and tangible medium. The data storage unit 532 may store the work plan information acquired from the server 4 and the identification information acquired from the on-board terminal 20.

[0027] The communication device 54 communicates with external devices including the onboard terminal 20 and / or the server 4 by wireless communication and / or wired communication via the network 3. A user terminal program as part of the work plan transfer program may be received by the communication device 54 from the outside and stored in the program storage unit 531. The communication device 54 may also perform wireless communication directly with the onboard terminal 20 without using the network 3.

[0028] The input / output device 55 outputs information to the user and accepts operations input by the user. As an example, the input / output device 55 may include a touch panel that integrates a display device that outputs images and a touchpad that accepts input by touch operation.

[0029] As shown in Fig. 4, the on-board terminal 20 according to one embodiment may be configured as a so-called computer, similar to the server 4 in Fig. 2 and the user terminal 5 in Fig. 3. In the example of Fig. 4, the on-board terminal 20 includes a bus 21, a computing device 22, a storage device 23, a communication device 24, an input / output device 25, and a control device 26. The bus 21 may be configured to realize communication between the computing device 22, the storage device 23, the communication device 24, the input / output device 25, and the control device 26.

[0030] The arithmetic device 22 executes an onboard terminal program included in a work plan transfer program according to one embodiment, thereby realizing the processing of each of the identification information transmission unit 221, work plan information acquisition unit 222, integrated work plan generation unit 223, work plan determination unit 224, and control unit 225. The identification information transmission unit 221 transmits identification information for identifying the onboard terminal 20 to the user terminal 5 in response to a request from the user terminal 5. The work plan information acquisition unit 222 receives and acquires determined work information transmitted from the user terminal 5. The integrated work plan generation unit 223 generates plan information based on the determined work information. The work plan determination unit 224 determines a work plan to be executed by the work device 2. The control unit 225 controls the work device 2 to perform work based on the determined work plan information.

[0031] The storage device 23 includes a program storage unit 231 and a data storage unit 232. The on-board terminal program as part of the work plan transfer program may be read from an external recording medium 230 and stored in the program storage unit 231. The recording medium 230 may be a non-transitory and tangible medium. The data storage unit 232 may store identification information of the on-board terminal 20 in advance. The data storage unit 232 may also store work plan information acquired from the user terminal 5.

[0032] The communication device 24 communicates with external devices including the user terminal 5 and / or the server 4 by wireless communication and / or wired communication via the network 3. An on-board terminal program as part of the work plan transfer program may be received by the communication device 24 from the outside and stored in the program storage unit 231. The communication device 24 may also perform wireless communication directly with the user terminal 5 without using the network 3.

[0033] The input / output device 25 outputs information to the user and accepts operations input by the user. As an example, the input / output device 25 may include a touch panel that integrates a display device that outputs images and a touchpad that accepts input by touch operations.

[0034] An example of the processing of a work plan transfer method according to an embodiment will be described with reference to the sequence diagram of Fig. 5. The sequence diagram of Fig. 5 shows an example of the operations performed by the server 4, the user terminal 5, and the onboard terminal 20 in the processing of a work plan transfer method according to an embodiment. As an example, the server 4 executes step S101 after startup, the user terminal 5 executes step S201 after startup, and the onboard terminal 20 executes step S301 after startup.

[0035] When the user terminal 5 executes step S201, more specifically, the work plan information acquisition unit 521 of the user terminal 5 in FIG. 3 transmits a signal requesting proposed work plan information to the server 4 as a work plan information request signal.

[0036] After step S201 in Fig. 5, the server 4 executes step S101. More specifically, in the server 4, the work plan information transmission unit 421 in Fig. 2 transmits the proposed work plan information to the user terminal 5 in response to the work plan information request signal transmitted from the user terminal 5 in step S201 in Fig. 5. The processing of the server 4 ends after step S101.

[0037] After step S101 in Fig. 5, the user terminal 5 executes step S202. More specifically, of the user terminal 5, the work plan information acquisition unit 521 in Fig. 3 acquires the proposed work plan information transmitted from the server 4 in step S101 in Fig. 5. The acquired proposed work plan information may be stored in the data storage unit 432 in Fig. 3.

[0038] After step S202 in FIG. 5 , the user terminal 5 executes step S203. More specifically, the identification information acquisition unit 522 in FIG. 3 of the user terminal 5 transmits a signal requesting identification information as an identification information request signal to the mounted terminal 20. At this time, even if multiple mounted terminals 20 are present within a range where communication with the user terminal 5 is possible, the identification information acquisition unit 522 does not distinguish between the multiple mounted terminals 20. Therefore, all mounted terminals 20 that can communicate with the user terminal 5 can receive the identification information request signal. Here, if the user terminal 5 and the multiple mounted terminals 20 are located within or near the field 9 that is the target of the proposed work plan, and wireless communication via the network 3 is difficult or impossible within or near the field 9, communication between the user terminal 5 and the multiple mounted terminals 20 may be performed by direct wireless communication that does not go through the network 3.

[0039] After step S203 in Fig. 5, each of the mounted terminals 20 that received the identification information request signal executes step S301. More specifically, of each mounted terminal 20, the identification information transmitting unit 221 in Fig. 4 transmits the respective identification information to the user terminal 5 in response to the identification information request signal transmitted from the user terminal 5 in step S203 in Fig. 5.

[0040] After step S301 in Fig. 5, the user terminal 5 executes step S204. More specifically, in the user terminal 5, the identification information acquisition unit 522 in Fig. 3 acquires the identification information transmitted from each of the mounted terminals 20 in step S301 in Fig. 5. The acquired identification information may be stored in the data storage unit 432 in Fig. 3.

[0041] After step S204 in Fig. 5, the user terminal 5 executes step S205. More specifically, the identification information acquisition unit 522 in Fig. 3 in the user terminal 5 determines whether the onboard terminal information included in the proposed work plan information acquired in step S202 in Fig. 5 matches the identification information acquired in step S204. If the result of the determination is that the onboard terminal information does not match any of the identification information (No), the processing of the user terminal 5 returns to step S203, and steps S203, S204, and S205 are repeated until identification information matching the onboard terminal information held by the user terminal 5 is acquired. If the result of the determination is that the onboard terminal information matches any of the identification information (Yes), the processing of the user terminal 5 proceeds to step S207.

[0042] In step S207 of FIG. 5, the user terminal 5 transmits the work plan information to the onboard terminal 20. More specifically, the work plan information transmission unit 524 of FIG. 3 of the user terminal 5 transmits the work plan information to the onboard terminal 20. Here, the work plan information includes proposed work plan information acquired from the server 4, and the proposed work plan information includes onboard terminal information. The work plan information transmission unit 524 of the user terminal 5 may determine the onboard terminal 20 to which the work plan information is to be transmitted in response to an operation by the user, and transmit the work plan information corresponding to the determined onboard terminal 20. Details of the operation by the user will be described later. Note that the work plan information transmitted by the work plan information transmission unit 524 of the user terminal 5 may be transmitted to other onboard terminals 20 that are capable of communicating with the user terminal 5, in addition to the target onboard terminal 20. The processing of the user terminal 5 ends after step S207.

[0043] After step S207 in Fig. 5, the onboard terminal 20 executes step S302. More specifically, the work plan information acquisition unit 222 in Fig. 4 of the onboard terminal 20 acquires the work plan information transmitted in step S207 in Fig. 5. The proposed work plan information included in the acquired work plan information may be stored in the data storage unit 232 in Fig. 4. Furthermore, the work plan information acquisition unit 222 of the onboard terminal 20 determines whether the onboard terminal information included in the proposed work plan information matches the identification information of the onboard terminal 20. If the result of the determination is that the onboard terminal information does not match the identification information (No), the processing of the onboard terminal 20 ends. If the result of the determination is that the onboard terminal information matches the identification information (Yes), the processing of the onboard terminal 20 proceeds to step S303.

[0044] In step S303 of Figure 5, the onboard terminal 20 generates an integrated work plan. More specifically, the integrated work plan generation unit 223 of the onboard terminal 20 in Figure 4 generates the integrated work plan based on the proposed work plan represented by the proposed work plan information and the current work plan represented by the current work plan information. Here, the integrated work plan generation unit 223 calculates a dispersion rate map for the integrated work plan based on the dispersion rate map for the proposed work plan and the dispersion rate map for the current work plan. Specific processing for generating the integrated work plan will be described later.

[0045] After step S303 in Fig. 4, the onboard terminal 20 executes step S304. More specifically, the work plan determination unit 224 in Fig. 4 of the onboard terminal 20 determines, in response to a user operation, a work plan to be executed by the work device 2 from among the current work plan, the proposed work plan, and the integrated work plan. The specific process by which the work plan determination unit 224 determines a work plan in response to a user operation will be described later.

[0046] After step S304 in Fig. 5, the onboard terminal 20 executes step S305. More specifically, the control unit 225 in Fig. 4 of the onboard terminal 20 controls the maintenance device 2 on which the onboard terminal 20 is mounted, and the maintenance device 2 executes the work of the work plan. The processing of the onboard terminal 20 ends after step S305.

[0047] Referring to Fig. 6, a process in which the work plan information transmitting unit 524 in Fig. 3 of the user terminal 5 transmits work plan information in step S207 in Fig. 5 will be described. Fig. 6 shows an example of information displayed on the touch panel 551 included in the input / output device 55 in Fig. 3 of the user terminal 5 in step S207 in Fig. 5.

[0048] In the example of FIG. 6 , the touch panel 551 displays a first window 56 and a second window 57. In the first window 56, images representing a first field 9A, a first work implement 2A located within the field 9A, a second field 9B, and a second work implement 2B located within the field 9B are displayed superimposed on a map of the area including the first field 9A and the second field 9B. The first window 56 also displays an icon 560 indicating the location of the user terminal 5 on the map, a first speech bubble 561 indicating information about the first work implement 2A, and a second speech bubble 562 indicating information about the second work implement 2B. The icon 560 may include an arrow indicating the direction in which the user terminal 5 is facing. Each of the balloons 561, 562 may display the connection status of the corresponding work device 2A, 2B with the user terminal 5 via wireless communication, the model, the model number, and the name.

[0049] The second window 57 displays a table showing information about the work devices 2, including the first work device 2A and the second work device 2B, that are located in the area represented by the map displayed in the first window 56. In the example of FIG. 6, the table in the second window 57 includes, for each work device 2, the status of wireless communication with the user terminal 5, the model, serial number, name, current plan identification number, and new plan distribution status. Here, the current plan refers to the current work plan represented by the current work plan stored in the data storage unit 232 of FIG. 4 of the on-board terminal 20 mounted on each work device 2. The new plan refers to the proposed work plan represented by the proposed work plan information scheduled to be transmitted from the user terminal 5 to the on-board terminal 20 mounted on each work device 2. The table in the second window 57 also includes an operation button for transmitting new plan information from the user terminal 5 to each work device 2.

[0050] The user operating the user terminal 5 refers to the various information displayed in the first window 56 and the second window 57, visually confirms the operation apparatus 2 equipped with the on-board terminal 20 to which the user terminal 5 will send the proposed work plan information, and then operates the operation button provided on the second window 57 to send the proposed work plan information. Note that, as in the case of the second operation apparatus 2B in the example of FIG. 6, step S207 in FIG. 5 does not need to be executed if a new plan has already been distributed or if the connection with the user terminal 5 is not yet established. In such cases, the processing of the user terminal 5 may end, or the process may return to step S201 in FIG. 5.

[0051] 7, 8 and 9, the process of generating an integrated work plan by the integrated work plan generating unit 223 of the on-board terminal 20 shown in FIG. 4 in step S303 shown in FIG. 5 will be described.

[0052] Figure 7 is a diagram illustrating an example of a spray rate map for a current work plan according to one embodiment. Figure 8 is a diagram illustrating an example of a spray rate map for a proposed work plan according to one embodiment. Figure 9 is a diagram illustrating an example of a spray rate map for an integrated work plan according to one embodiment. Hereinafter, for convenience, the spray rate map for the current work plan will be referred to as the current spray rate map, the spray rate map for the proposed work plan will be referred to as the proposed spray rate map, and the spray rate map for the integrated work plan will be referred to as the integrated spray rate map.

[0053] The current application rate map of FIG. 7 and the proposed application rate map of FIG. 8 show the same field 9 virtually divided into multiple regions, and the layout of the multiple regions in the field 9 is the same in FIG. 7 and FIG. 8. In the current application rate map of FIG. 7 and the proposed application rate map of FIG. 8, the numerical values ​​shown in each region represent the amount of product to be applied to each region. The integrated application rate map of FIG. 9 shows the same field 9 as in FIG. 7 and FIG. 8, and the layout of the multiple regions into which the field 9 is virtually divided is the same as in FIG. 7 and FIG. 8. In the integrated application rate map of FIG. 9, the numerical values ​​shown in each region represent the amount of product to be applied to each region, and are the weighted average of the numerical values ​​in the corresponding region in the current application rate map of FIG. 7 and the numerical values ​​in the corresponding region in the proposed application rate map of FIG. 8. The weighted average value is calculated for each corresponding region by adding a first product obtained by multiplying the values ​​in the current spray rate map of Figure 7 by a first ratio to a second product obtained by multiplying the values ​​in the proposed spray rate map of Figure 8 by a second ratio, and dividing the resulting first sum by a second sum obtained by adding the first ratio to the second ratio. As an example, the first ratio and the second ratio may be determined in advance before step S303 of Figure 5 is executed. In the example of Figure 9, the first ratio and the second ratio are both 50%.

[0054] 10 and 11, a process in which the work plan determination unit 224 of Fig. 4 of the on-board terminal 20 determines a work plan in step S304 of Fig. 5 will be described. Fig. 10 and Fig. 11 each show an example of information displayed on the touch panel 251 included in the input / output device 25 of Fig. 4 of the on-board terminal 20 in step S304 of Fig. 5.

[0055] 5 is executed, the onboard terminal 20 transitions to a state in which the user of the onboard terminal 20 can check the various work plans stored in the data storage unit 232 of FIG. 4, and the contents shown in FIG. 10 are displayed on the touch panel 251 of the onboard terminal 20. In the example of FIG. 10, information indicating the user terminal 5 as the download source that transmitted the proposed work plan information, the type of new plan as the proposed work plan represented by the proposed work plan information transmitted from the user terminal 5, and the type of current plan as the current work plan represented by the current work plan information stored in the data storage unit 232 of the onboard terminal 20 in FIG. 4 are displayed as a table 260 on the touch panel 251. The touch panel 251 also displays a first button 261, a second button 262, a third button 263, and a fourth button 264.

[0056] The first button 261 in Fig. 10 is provided for transitioning to a state where a plan can be confirmed and edited. More specifically, when a user operating the onboard terminal 20 operates the first button 261 in Fig. 10, the onboard terminal 20 transitions to a state where the user can confirm the contents of each work plan and edit any one of the current work plan, the proposed work plan, or the integrated work plan as an adopted work plan that will actually be executed by the work device 2, and the display on the touch panel 251 switches to the display in Fig. 11.

[0057] 11 , the following are displayed on the touch panel 251 as a table 270: a fifth button 271 operated to display the name of the field 9 and details of the field 9; information indicating whether a current plan as the current work plan and a new plan as the proposed work plan are stored in the data storage unit 232 of FIG. 4; information indicating whether a plan difference exists between the current work plan and the proposed work plan; the type of adopted work plan to be executed by the work device 2; and a sixth button 272 for selecting the adopted work plan. The touch panel 251 also displays a seventh button 273 and an eighth button 274 operated to save the results of selecting the adopted work plan. When the seventh button 273 or the eighth button 274 is operated, the on-board terminal 20 returns to a state in which the user of the on-board terminal 20 can check and start the various work plans stored in the data storage unit 232 of FIG. 4 , and the display on the touch panel 251 returns to the display of FIG. 10 .

[0058] The second button 262 in Fig. 10 is provided for overwriting the current work plan with the proposed work plan or the integrated work plan and adopting it as a new plan. More specifically, when the user of the on-board terminal 20 operates the second button 262 in Fig. 10, the work plan determination unit 224 in Fig. 4 overwrites the current work plan information stored in the data storage unit 232 in Fig. 4 with work plan information representing the work plan adopted on the screen in Fig. 11. Note that the next time the work plan transfer method according to one embodiment shown in the sequence diagram of Fig. 5 is executed, the currently adopted work plan will be used as the next current work plan.

[0059] The third button 263 in Fig. 10 is provided for discarding the proposed work plan or integrated work plan as a new plan without adopting it, and for retaining the current work plan. More specifically, when the user of the on-board terminal 20 operates the third button 263 in Fig. 10, the work plan determination unit 224 in Fig. 4 discards the proposed work plan and the integrated work plan, regardless of which work plan was adopted on the screen in Fig. 11, and retains the current work plan information stored in the data storage unit 232 in Fig. 4. It should be noted here that the next time the work plan transfer method according to one embodiment shown in the sequence diagram of Fig. 5 is executed, the current current work plan will be used as the next current work plan.

[0060] When the user of the onboard terminal 20 operates the second button 262 or the third button 263 in Fig. 10, a work plan to be carried out by the operation device 2 under the control of the onboard terminal 20 is determined in step S305 in Fig. 5. Thereafter, when the user of the onboard terminal 20 operates the fourth button 264 in Fig. 10, the processing of the onboard terminal 20 proceeds to step S305 in Fig. 5.

[0061] 10, a process in which the control unit 225 of the onboard terminal 20 in FIG. 4 controls the maintenance device 2 in step S305 of FIG. 5 will be described. When step S305 of FIG. 5 is executed, the control unit 225 of the onboard terminal 20 in FIG. 4 controls the maintenance device 2 to start and execute the work of the work plan determined in step S304 of FIG.

[0062] (Variation) 5, the processing of the user terminal 5 ends after step S207, and the processing of the onboard terminal 20 ends when the result of the determination in step S302 is "No" or ends after step S305. As a variation of this configuration, the server 4, the user terminal 5, and the onboard terminal 20 may repeat their respective processes. More specifically, the processing of the server 4 may return to step S101 after step S101, the processing of the user terminal 5 may return to step S201 after step S207, and the processing of the onboard terminal 20 may return to step S301 after step S302 or step S305.

[0063] As described above, the work plan transfer method, work plan transfer system 1, and work plan transfer program according to one embodiment can efficiently transfer the determined work plan to the on-board terminal 20 by determining a determined work plan to be actually executed by the work device 2 based on the proposed work plan acquired by the user terminal 5 from the server 4 and the current work plan pre-stored in the user terminal 5.

[0064] (Second embodiment) In the above embodiment, a configuration was described in which the on-board terminal 20 performs the process of generating an integrated work plan based on the current work plan and the proposed work plan. In this embodiment, as a variation of this configuration, a configuration will be described in which the user terminal 5 performs the process of calculating the integrated work plan. The work plan transfer method, work plan transfer system 1, and work plan transfer program according to this embodiment can be obtained by making the following changes to the work plan transfer method, work plan transfer system 1, and work plan transfer program according to the first embodiment. The changed parts will be mainly described below.

[0065] As shown in Fig. 12, the user terminal 5 according to this embodiment is obtained by adding an integrated work plan generation unit 523 to the arithmetic device 52 of the user terminal 5 according to the first embodiment shown in Fig. 3. Other configurations of the user terminal 5 according to this embodiment may be similar to the configurations of the user terminal 5 according to the first embodiment. Note that the user terminal 5 according to the first embodiment may further include the integrated work plan generation unit 523 of Fig. 12.

[0066] As shown in Fig. 13, the onboard terminal 20 according to this embodiment can be obtained by removing the integrated work plan generation unit 223 from the arithmetic device 22 of the onboard terminal 20 according to the first embodiment shown in Fig. 4. Other configurations of the onboard terminal 20 according to this embodiment may be similar to those of the onboard terminal 20 according to the first embodiment. Note that the onboard terminal 20 according to this embodiment may also include the integrated work plan generation unit 223 of Fig. 4.

[0067] The server 4 according to this embodiment is the same as the server 4 according to the first embodiment shown in FIG.

[0068] An example of the processing of the work plan transfer method according to this embodiment will be described with reference to the sequence diagram of Fig. 14. The processing of the sequence diagram shown in Fig. 14 can be obtained by making the following changes to the processing of the sequence diagram according to the first embodiment shown in Fig. 5. That is, in the processing of the user terminal 5, step S206 is added between step S205 and step S207, and step S303 is removed from the processing of the on-board terminal 20.

[0069] More specifically, in the processing of the user terminal 5 according to this embodiment, if the result of the determination made in step S205 is that the on-board terminal information and the identification information match (Yes), the processing proceeds to step S206. In step S206, the integrated work plan generation unit 523 of the user terminal 5 (FIG. 12) generates an integrated work plan based on the current work plan and the proposed work plan. The processing for generating the integrated work plan may be performed in the same manner as the processing of step S303 of the on-board terminal 20 in the first embodiment. At this time, the user terminal 5 may perform processing similar to the information display and operation acceptance performed by the on-board terminal 20 in the first embodiment. Note that in this embodiment, current work plan information representing the current work plan is pre-stored in the data storage unit 532 of the user terminal 5 (FIG. 12).

[0070] 14, the processing of the user terminal 5 proceeds to step S207. In step S207, the work plan information transmission unit 524 of the user terminal 5 in FIG. 12 transmits the proposed work plan information and integrated work plan information representing the integrated work plan to the on-board terminal 20. Other processing of the user terminal 5 is the same as the processing of the user terminal 5 according to the first embodiment.

[0071] Furthermore, in step S302 of the processing of the onboard terminal 20 according to this embodiment, the work plan information acquisition unit 222 of the onboard terminal 20 shown in Fig. 13 receives and acquires the proposed work plan information and integrated work plan information transmitted by the user terminal 5 in step S207 of Fig. 14. The acquired proposed work plan information and integrated work plan information may be stored in the data storage unit 232 of Fig. 13. Thereafter, the work plan information acquisition unit 222 determines whether the onboard terminal information included in the proposed work plan information matches the identification information of the onboard terminal 20, as in step S302 of Fig. 5.

[0072] 13, if the on-board terminal information matches the identification information (Yes), the processing of the on-board terminal 20 proceeds to step S304. Other processing of the on-board terminal 20 is the same as the processing of the on-board terminal 20 according to the first embodiment.

[0073] As described above, the work plan transfer method, work plan transfer system 1, and work plan transfer program according to this embodiment enable the proposed work plan information to be efficiently transferred from the user terminal 5 to the on-board terminal 20, and furthermore, the user terminal 5 generates an integrated work plan, thereby reducing the processing load on the on-board terminal 20.
