[Automatic driving system 1]
As shown in FIGS. 1 and 2, the automatic driving system 1 according to the embodiment of the present invention includes a work vehicle 10, a server 20, a management operation terminal 30, a portable operation terminal 40, a base station 50, a satellite 60. The work vehicle 10, the server 20, the management operation terminal 30, and the portable operation terminal 40 can communicate via the communication network N1. For example, the server 20, the work vehicle 10, the management operation terminal 30, and the portable operation terminal 40 can communicate with each other via a mobile phone network, a packet network, or a wireless LAN.

In the present embodiment, an example will be described in which the work vehicle 10 is a vehicle that performs a spraying operation of spraying a sprayed material such as a chemical (chemical solution) on crops V (see FIG. 7) planted in a field F. . The farm field F is an example of the working land of the present invention, and the farm field F is, for example, an orchard such as a vineyard or an apple orchard. A crop V is an example of the work object of the present invention, and the crop V is, for example, a fruit tree of grapes. The spraying work is an example of the work of the present invention, and the spraying work is, for example, a work of spraying a sprayed material such as a chemical solution on the crop V. As another embodiment, the working vehicle 10 may be a weeding vehicle, a leaf cutting vehicle, or a harvesting vehicle. The work of the present invention may be a weeding work, a leaf cutting work, a harvesting work, or the like.

The crops V are arranged in a plurality of rows in the field F at predetermined intervals. Specifically, as shown in FIG. 7, a plurality of crops V are planted in a straight line in a predetermined direction (d1 direction) to form a crop row Vr including a plurality of crops V arranged in a straight line. . FIG. 7 illustrates three crop rows Vr. Each crop row Vr is arranged at a predetermined interval W1 in the row direction (d2 direction). A region (space) with an interval W2 between adjacent rows of crops Vr serves as a work passage for the work vehicle 10 to spray the crops V while traveling in the direction d1.

Further, the work vehicle 10 can automatically travel (autonomously travel) according to a preset target route R. For example, as shown in FIG. 8, the work vehicle 10 automatically travels from a work start position S to a work end position G along a target route R including a work route r1 (work routes r1a to r1f) and a movement route r2. The work route r1 is a linear route along which the work vehicle 10 sprays the crop V, and the movement route r2 is a route along which the work vehicle 10 moves between the crop rows Vr without spraying. . The movement route r2 includes, for example, a turning route and a straight route. In the example shown in FIG. 8, in a field F, crops V are arranged in rows of crops Vr1 to Vr11. In FIG. 8, the position where the crop V is planted (crop position) is represented by "Vp". Further, the work vehicle 10 traveling in the field F of FIG. 8 has a vehicle body 100 having a gate shape (see FIG. 6), and while traveling across one crop row Vr, The chemical is sprayed on the crop V and the crop row Vr adjacent to the crop row Vr. For example, as shown in FIG. 8, when the work vehicle 10 travels across the crop row Vr5, the left vehicle body (left side 100L) of the work vehicle 10 travels in the work passage between the crop rows Vr4 and Vr5, and the work vehicle 10 right vehicle body (right side 100R) travels in the working passage between crop rows Vr5 and Vr6 and sprays the crops V of crop rows Vr4, Vr5 and Vr6 with chemicals.

Further, the work vehicle 10 automatically travels in a predetermined row order. For example, the work vehicle 10 travels across the crop row Vr1, then across the crop row Vr3, and then across the crop row Vr5. In this manner, the work vehicle 10 automatically travels according to the preset order of the crop rows Vr. In addition, the work vehicle 10 may run for each row in the order in which the rows of crops Vr are arranged, or may run for every two or more rows.

The satellite 60 is a positioning satellite that constitutes a satellite positioning system such as GNSS (Global Navigation Satellite System), and transmits a GNSS signal (satellite signal). The base station 50 is a reference point (reference station) that configures the satellite positioning system. The base station 50 transmits correction information for calculating the current position of the work vehicle 10 to the work vehicle 10 .

The positioning device 16 mounted on the work vehicle 10 uses GNSS signals transmitted from the satellites 60 to perform positioning processing for calculating the current position (latitude, longitude, altitude) and current direction of the work vehicle 10 . Specifically, the positioning device 16 determines the position of the work vehicle 10 based on positioning information (such as a GNSS signal) received by two receivers (the antenna 164 and the base station 50) and correction information generated by the base station 50. The position of the work vehicle 10 is determined using an RTK (Real Time Kinematic) method or the like. Since the positioning method is a well-known technique, detailed description thereof will be omitted.

The storage unit 12 is a non-volatile storage unit such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive) that stores various types of information. The storage unit 12 stores a control program for causing the vehicle control device 11 to execute predetermined control processing (for example, automatic driving processing). For example, the control program is non-temporarily recorded on a computer-readable recording medium such as a CD or DVD, read by a predetermined reader (not shown), and stored in the storage unit 12 . The control program may be downloaded to the work vehicle 10 from a server (for example, the server 20) via the communication network N1 and stored in the storage unit 12. The storage unit 12 also stores data of the target route R generated by the management operation terminal 30 . For example, data of the target route R is transmitted from the management operation terminal 30 to the server 20 , transferred from the server 20 to the work vehicle 10 and stored in the storage unit 12 .

The vehicle control device 11 has control devices such as a CPU, ROM, and RAM. The CPU is a processor that executes various kinds of arithmetic processing. The ROM is a non-volatile storage unit in which control programs such as BIOS and OS for causing the CPU to execute various arithmetic processes are stored in advance. The RAM is a volatile or nonvolatile storage unit that stores various information, and is used as a temporary storage memory (work area) for various processes executed by the CPU. The vehicle control device 11 controls the work vehicle 10 by causing the CPU to execute various control programs pre-stored in the ROM or the storage unit 12 .

The vehicle control device 11 controls traveling of the work vehicle 10 . Specifically, the vehicle control device 11 causes the work vehicle 10 to automatically travel along the target route R based on the position information indicating the position of the work vehicle 10 measured by the positioning device 16 . For example, when the positioning state becomes a state in which RTK positioning is possible and the worker performs a work start operation on the operation screen of the portable operation terminal 40, the portable operation terminal 40 sends a work start instruction to the work vehicle 10 via the server 20. output to Upon acquiring the work start instruction, the vehicle control device 11 causes the work vehicle 10 to start automatically traveling based on the position information indicating the position of the work vehicle 10 measured by the positioning device 16 . Specifically, when the worker performs a work start operation on the portable operation terminal 40, the worker manually moves the work vehicle 10 to the work start position S, and presses the start button of the remote controller (not shown) at the work start position S. Press As a result, the vehicle control device 11 causes the work vehicle 10 to start automatically traveling from the work start position S. As shown in FIG. The work vehicle 10 starts automatically traveling along the target route R, and starts the spraying work by the spraying device 14 in the work passage.

Further, the vehicle control device 11 stops the automatic travel of the work vehicle 10 when receiving a travel stop instruction from the portable operation terminal 40 . For example, when the operator presses a stop button on the operation screen of the portable operation terminal 40 , the portable operation terminal 40 outputs the travel stop instruction to the work vehicle 10 via the server 20 . When the vehicle control device 11 acquires the travel stop instruction from the portable operation terminal 40 , the vehicle control device 11 stops the automatic travel of the work vehicle 10 . As a result, the work vehicle 10 stops automatically traveling, and the spraying work by the spraying device 14 is stopped.

The work vehicle 10 includes a gate-shaped vehicle body 100 that runs across crops V (fruit trees) planted in a plurality of rows in a field F. As shown in FIG. 6, the vehicle body 100 is formed in a gate shape by a left side portion 100L, a right side portion 100R, and a connection portion 100C connecting the left side portion 100L and the right side portion 100R. A space 100S that allows the passage of the crop V is secured inside the 100R and the connecting portion 100C.

The left and right crawlers 101 are driven by power from the engine in a state in which independent speed change is possible by a hydrostatic continuously variable transmission. As a result, the left and right crawlers 101 are driven in the forward direction at a constant speed, so that the vehicle body 100 moves straight in the forward direction. It will be in a backward state to go straight. In addition, the left and right crawlers 101 are driven at a non-uniform speed in the forward direction, so that the vehicle body 100 is in a forward turning state in which the vehicle body 100 turns while moving forward. It will be in a backward turning state to turn while turning. When one of the left and right crawlers 101 is stopped and the other crawler 101 is driven, the vehicle body 100 enters a pivot turning state (pivot turning), and the left and right crawlers 101 move forward and backward. By being driven at a constant speed in both directions, it becomes a spin turning (super pivot turning) state. In addition, the vehicle body 100 is in a running stop state by stopping the driving of the left and right crawlers 101 .

A person column R7, a model column R8 for registering the model of the work vehicle 10, and the like are included.

The creation processing unit 313 creates a work plan for each field F. FIG. Specifically, the field manager selects the date button K1 on the registration screen D1 to determine the scheduled work date. FIG. 9 shows a state in which "March 1st" is selected. Next, the field manager selects the target field F for the work plan on the map Mp. For example, the field manager selects field A1. The creation processing unit 313 is an example of the creation processing unit of the present invention.

Next, the field manager registers each item in the registration field R0. For example, in the working time registration field R1, the field manager registers the working time indicating whether the work is to be done in the morning, the work is to be done in the afternoon, or whether the work is to be done at any time. Here, the display processing unit 312 displays the area of the agricultural field A1 in the area column R2. For example, the display processing unit 312 displays an area registered in advance or an area calculated from the map Mp in the area column R2. In addition, the display processing unit 312 displays the working time (spraying time) in the working time column R3. Specifically, the calculation processing unit 314 calculates the spraying time of the spraying work based on the target route R of the field A1. For example, the calculation processing unit 314 calculates the spraying time based on information such as the area of the farm field A1, the traveling speed of the work vehicle 10, the target route R, and the working machine. Further, the calculation processing unit 314 calculates the spraying time based on work history information (details will be described later) of the past spraying work of the field A1. The display processing unit 312 displays the calculated spraying time in the work time column R3. The field manager can change the area displayed in the area column R2 and the spraying time displayed in the work time column R3. The calculation processing unit 314 is an example of the calculation processing unit of the present invention.

Also, the field manager selects a work type in the work type column R4. Here, the field manager selects "scattering".

In addition, the display processing unit 312 displays the total amount of medicine in the medicine column R5, and displays the total amount of water in the water column R6. Specifically, the calculation processing unit 314 calculates the total amount of chemicals and the total amount of water based on the target route R of the field A1. The calculation processing unit 314 also calculates the total amount of chemicals and the total amount of water based on work history information (details will be described later) of past spraying operations in the field A1. The total amount of chemicals and water is an example of the application rate of the present invention. The display processing unit 312 displays the calculated total amount of medicine in the medicine column R5, and displays the calculated total amount of water in the water column R6. The field manager can change the total amount of chemicals displayed in the chemical field R5 and the total amount of water displayed in the water content field R6.

In addition, the farm field manager selects the worker who performs the spraying work in the farm field A1 in the worker column R7. Here, the field manager selects worker P1. In addition, the field manager selects the model of the work vehicle 10 that performs the spraying work in the model column R8. Here, the field manager selects the model "M1".

The field manager presses the registration button (“CREATE”) when the registration operation for each item in the registration column R0 is completed. As a result, the creation processing unit 313 creates a work plan including work information (information on items R1 to R8) related to the spraying work to be carried out on “March 1” in the field A1.

Subsequently, the farm field manager, for example, performs a registration operation of another scheduled work date (for example, "March 8") for the farm field A1, or performs a registration operation of a scheduled work date for another farm field F (for example, a farm field A2). to do

In this way, the creation processing unit 313 creates a work plan for each field F according to the registration operation of the field manager. The creation processing unit 313 outputs the data of the work plan to the server 20 each time the work plan corresponding to each field F is created. Information on the target route R may be included in the work plan.

The server 20 saves and manages the work plan for each field F. The server 20 also displays the work plan for each farm field F on the registration screen D1 of the management operation terminal 30 . Specifically, the display processing unit 312 causes the work plan list Sr (see FIG. 9) to display the work plan information for each field F managed by the server 20 as a list.

The registration screen D1 (see FIG. 9) has a function of displaying the registered work plan in addition to a function of registering the work plan. Therefore, the field manager and the workers of each field F can confirm the work plan of each field F for each date by viewing the registration screen D1.

In addition, the registration screen D1 further displays work information ( It has a function (announcement function) for announcing information). A specific configuration of the notification function will be described below.

The determination processing unit 315 acquires one or more work plans. In addition, the determination processing unit 315 selects, among the plurality of work plans, a work plan (first work plan of the present invention) that requires attention so that the work vehicle 10 can perform the work as planned in the work plan. exists. In addition, the notification processing unit 316 notifies the work information (notification information) related to the work plan when there is a work plan requiring attention among the plurality of work plans.

FIG. 10 shows an example of the registration screen D1. In the example shown in FIG. 10, "March 5" is selected by the field manager, and the work status as of "March 5" is displayed on the map Mp of the registration screen D1. Specifically, the determination processing unit 315 determines whether or not there is a work plan whose work has not been completed at the present time (“March 5” in FIG. 10) among the plurality of work plans. For example, the server 20 acquires information about the work status of each field F from the work vehicle 10 and the portable operation terminal 40, and manages the start, interruption, and end of work corresponding to the work plan. The server 20 also stores work history information (see FIG. 13) corresponding to the work plan for each field F. FIG. The work history information includes work date, work time, application amount, chemical type, worker, model of work vehicle 10, position information, and the like.

The determination processing unit 315 acquires one or a plurality of work plans by referring to the work history information, for example, and at the time of "March 5", the scheduled work date before "March 5" is registered. It is determined whether or not there is a work plan that has been completed and the work has not been completed. For example, when the worker fails to complete the work on the scheduled work date or forgets to do the work, information indicating that the work has not been completed is registered in the work history information. The determination processing unit 315 determines whether or not the work for each work plan is being carried out as planned in the work plan by referring to the work history information. The determination processing unit 315 is an example of the acquisition processing unit and the determination processing unit of the present invention.

If there is a work plan for which work has not been completed at the present time (“March 5” in FIG. 10) among the plurality of work plans, the notification processing unit 316 notifies work information related to the work plan. Specifically, the notification processing unit 316 causes the field F corresponding to the work plan to be identifiably displayed on the map Mp of the registration screen D1 shown in FIG. For example, for field A6, a work plan is registered with "March 3" as the scheduled work date for the spraying work, and the spraying work for field A6 has not been completed at the present time ("March 5"). Furthermore, as shown in FIG. 10, the notification processing unit 316 highlights the background image Fs of the field A6 to display the field A6 (an example of the first work land of the present invention) in an identifiable manner. As another embodiment, the notification processing unit 316 may display a flag on the agricultural field A6. As a result, the field manager and the worker can grasp the fields F on which work has not been performed on the scheduled work day, the fields F on which the work has not been completed on the scheduled work day, and the like. Then, for example, the field manager can re-register the work plan for the spraying work for the field A6, and the worker can carry out the spraying work for the field A6 on the same day. The notification processor 316 is an example of the notification processor of the present invention.

Note that the notification processing unit 316 displays, on the map Mp of the registration screen D1, the fields F in which the scheduled work date has passed and in which no work has been performed and the fields F in which the work has been interrupted. They may be displayed in different display modes so that they can be identified. As a result, the farm field manager and the worker can identify and grasp the farm field F on which no work is being performed and the farm field F on which the work has been interrupted. Further, the notification processing unit 316 may display the farm field F in which the work plan after the current day is registered so as to be distinguishable from the other farm fields F on the map Mp of the registration screen D1.

Further, as another embodiment, the notification processing unit 316 may display the number of days elapsed from the scheduled work date to the current date in association with the field F. FIG. In the example of FIG. 10 , the notification processing unit 316 displays the elapsed days “2 days” from “March 3rd” to “March 5th” in association with the agricultural field A6. As a result, the field manager and the worker can grasp the number of days that have elapsed from the scheduled work date to the current date.

Here, in the example shown in FIG. 10, the field manager has set the elapsed days button K3 for selecting the number of days elapsed since the previous work day to "5 days". Specifically, for example, in fields A1 to A12, the field manager confirms (extracts ), the elapsed days button K3 is set to "5 days".

The determination processing unit 315 determines whether or not there is a work plan in which a predetermined number of days or more have elapsed from the work date on which the previous work was performed to the current date, among the plurality of work plans. For example, the determination processing unit 315 refers to the work history information and determines whether there is a work plan in which "five days" or more have passed since the work date of the previous spraying work as of "March 5". judge.

If a plurality of work plans include a work plan for which a predetermined number of days ("five days" in FIG. In the map Mp of the registration screen D1 shown in 10, the number of days elapsed from the date of the previous work to the current date is displayed in association with the field F. For example, if 5 days have passed since the previous spraying work for the field A3, the notification processing unit 316 displays a days flag Fg indicating that 5 days have passed in association with the field A3. The example shown in FIG. 10 indicates that 6 days have passed since the previous spraying work day for fields A7 and A9, and that 7 days have passed since the previous spraying work day for field A10. It means that As a result, the farm field manager and workers can grasp the farm field F where the next spraying work needs to be carried out immediately. Then, for example, the farm field manager can register a work plan for the next spraying work for the farm field F. FIG.

Further, as another embodiment, the notification processing unit 316, when there is a work plan in which the work content is a work that is repeatedly performed at a predetermined cycle and the scheduled work date is not registered at a predetermined cycle, The field F corresponding to the work plan may be displayed in an identifiable manner.

Specifically, the determination processing unit 315 determines that, among the plurality of work plans, the work content is a spraying work that is repeatedly performed at a predetermined cycle (for example, one week or two weeks), and the scheduled work date is the predetermined work schedule. It is determined whether or not there is a work plan that has not been registered in the period of . For example, the determination processing unit 315 refers to the work plan for each field F stored in the server 20 and executes the determination process.

The notification processing unit 316 detects when, among a plurality of work plans, there is a work plan whose work content is a spraying work that is repeatedly performed at a predetermined cycle and whose scheduled work date is not registered at the predetermined cycle. Then, the farm field F corresponding to the work plan is identifiably displayed on the map Mp of the registration screen D1. For example, when it is necessary to carry out spraying work every week in field A8, the spraying work was carried out one week before the current day "March 5", and the work plan for the spraying work is registered for the current day. If not, the notification processing unit 316 causes the field A8 to be identifiably displayed on the map Mp. In addition, the notification processing unit 316 may display information prompting registration of the work plan for the field A8. Thereby, the field manager and the worker can grasp that the work plan of the spraying work for the field A8 is not registered.

By the way, among the work performed by the work vehicle 10, there is work that is easily affected by the weather. For example, in spraying work, if it rains after spraying a chemical agent on the crop V, the chemical agent is washed away by the rain, and the effect of the chemical agent on the crop V is reduced. Therefore, for example, immediately after it rains, it is necessary to spray chemicals. Therefore, as another embodiment, the notification processing unit 316 may notify notification information according to the weather.

Specifically, the determination processing unit 315 determines whether or not there is a work plan in which the weather forecast for the scheduled day of work is predicted to be rainy among the plurality of work plans. Note that the determination processing unit 315 acquires weather forecast information for a predetermined area including the field F by a well-known method. Further, the display processing unit 312 may display weather forecast information on the date button K1 of the registration screen D1 (see FIGS. 9 and 10).

The notification processing unit 316 notifies the work information regarding the work plan when there is a work plan in which the weather forecast for the scheduled work date is predicted to be rainy among the plurality of work plans. Specifically, when there is a work plan among a plurality of work plans in which the weather forecast for the scheduled work date is predicted to be rainy, the notification processing unit 316 determines the content of the predetermined work that needs to be performed after the rain. When the scheduled work date is not registered, the farm field F corresponding to the work plan is identifiably displayed on the map Mp of the registration screen D1. For example, in the field A12, if it rained immediately after the spraying work was carried out on "March 4th", and if the work plan for the spraying work is not registered for the next day "March 5th", the notification process is performed. The unit 316 causes the field A12 to be identifiably displayed on the registration screen D1 for "March 5". Note that the notification processing unit 316 may display information prompting registration of the work plan for the spraying work for the field A12. As a result, the field manager and the worker can understand that the spraying work for the field A12 is necessary.

Further, among the work performed by the work vehicle 10, there is a work in which entry is prohibited for a predetermined period after the end of the work. For example, in the spraying work, after spraying the chemical on the crop V, entry into the field F is prohibited for 24 to 48 hours. Therefore, as another embodiment, the notification processing unit 316 may notify the information of the restricted area.

Specifically, the determination processing unit 315 determines that, among the plurality of work plans, there is a work plan whose work content is work in which entry into the field F is prohibited for a predetermined period after the work vehicle 10 performs the work. Determine if it exists.

The notification processing unit 316, when there is a work plan whose work content is work in which entry into the field F is prohibited for a predetermined period after the work vehicle 10 performs the work, among the plurality of work plans, On the map Mp of the registration screen D1, it is identifiably displayed that the field F corresponding to the work plan is off-limits for a predetermined period. For example, if 48 hours have not passed since the spraying work was performed on the fields A2, A4, and A11, the notification processing unit 316 highlights the background images Ft of the fields A2, A4, and A11. For example, each field is displayed in an identifiable manner. Note that the determination processing unit 315 may set the no-entry period according to the type of medicine. In addition, the notification processing unit 316 may display the elapsed time after entry is prohibited, the remaining time until the entry prohibition is lifted, or the like, or display the background image Ft according to the elapsed time or the remaining time may be changed.

As described above, the notification processing unit 316 displays a work plan (main Work information related to the first work plan of the invention) is notified.

As another embodiment, the notification processing unit 316 may display the work information in the schedule table Sd of the schedule screen D2 displayed on the management operation terminal 30. FIG. FIG. 11 shows an example of the schedule screen D2. For example, on the registration screen D1 shown in FIG. 10, when the field manager presses the menu button Mb and selects "schedule", the display processing unit 312 causes the management operation terminal 30 to display the schedule screen D2. A work plan for each field F, a work plan for each worker, a work plan for each model of the work vehicle 10, and the like are displayed on the schedule screen D2. FIG. 11 shows an example of a work plan for each field F. As shown in FIG.

The display processing unit 312 causes the schedule table Sd to list the information of the work plan for each field F managed by the server 20 . Specifically, the display processing unit 312 displays an icon C1 corresponding to the work plan in the date column of the scheduled work date in the schedule table Sd. In addition, in the schedule table Sd, the notification processing unit 316 includes work information ( notification information).

For example, if there is a work plan whose work has not been completed at the present time (“March 5” in FIG. 10) among the plurality of work plans, the notification processing unit 316 detects that in the schedule table Sd shown in FIG. , the farm field F corresponding to the work plan is identifiably displayed. For example, when a work plan is registered with "March 3" as the scheduled work date of the spraying work for field A6, the notification processing unit 316, as shown in FIG. The warning information Cm is displayed in the date column of "3 days", and the background image of the date column is highlighted. In addition, the notification processing unit 316 highlights the background image Fm of the name of the field A6 in the schedule Sd.

In addition, the notification processing unit 316, when there is a work plan in which a predetermined number of days ("five days" in FIG. 10) has passed from the work date when the previous work was performed to the current day among the plurality of work plans, In the schedule table Sd of the schedule screen D2 shown in FIG. 11, the number of days elapsed from the date of the previous work to the current date may be displayed in association with the field (not shown).

In addition, the notification processing unit 316 determines that among the plurality of work plans, there is a work plan whose work content is a spraying work that is repeatedly performed at a predetermined cycle and whose scheduled work date is not registered at the predetermined cycle. In this case, the field F corresponding to the work plan may be identifiably displayed in the schedule table Sd of the schedule screen D2 (not shown).

In addition, when there is a work plan in which the weather forecast for the scheduled work date is expected to be rainy among a plurality of work plans, the notification processing unit 316 sets the scheduled work date for a predetermined work content that needs to be performed after the rain. is not registered, the field F corresponding to the work plan may be identifiably displayed in the schedule table Sd of the schedule screen D2 (not shown).

In addition, the notification processing unit 316 detects a work plan in which there is a work plan in which entry to the field F is prohibited for a predetermined period after the work vehicle 10 performs the work. In addition, in the schedule table Sd of the schedule screen D2, it may be identifiably displayed that the field F corresponding to the work plan is off-limits for a predetermined period. For example, if 48 hours have not passed since the spraying work was performed on the fields A2 and A4, the notification processing unit 316 displays the background images of the fields A2 and A4 on the schedule Sd of the schedule screen D2. Each field is displayed so as to be identifiable, for example, by highlighting C2. Note that the notification processing unit 316 may display the entry prohibition period for past dates, such as the field A1 and the field A5, or display the entry prohibition period for dates after the current date (future), such as the field A5. period may be displayed.

Further, as another embodiment, the notification processing unit 316 displays an icon C1 corresponding to the field F (field A5 in FIG. 11) in which the work plan after the current day is registered, It may be displayed so as to be identifiable from the icon C1 of another field F.

As described above, the notification processing unit 316 displays a work plan ( Work information related to the first work plan of the present invention) is notified. As described above, the notification processing unit 316 according to the present embodiment notifies the work information in at least one of the map Mp (see FIG. 10) and the schedule table Sd (see FIG. 11). This allows the field manager and the worker to grasp the work plan that requires attention so that the work vehicle 10 can perform the work as planned in the work plan, the work that is not progressing as planned in the work plan, and the like. becomes possible.

FIG. 14 shows an example of the recipe information screen Dr. For example, in the registration screen D1 shown in FIG. 9, when the field manager selects the icon in the drug column R5, the display processing unit 312 displays the recipe information screen Dr. The recipe information screen Dr displays information about drugs included in the work history information (see FIG. 13). For example, FIG. 14 shows “recipe 1” composed of chemicals “n1”, “n2”, and “n3” used in the past spraying work of field A1. In addition, the usage amount is displayed for each drug. The amount used may be the amount used per unit area, or the total amount actually used. Further, when a plurality of recipe information are associated with the field A1, the field manager displays other recipe information by pressing the recipe selection field Rp, and selects a desired recipe. be able to.

Note that the control unit 31 registers recipe information based on work history information of the past spraying work of the field F. FIG. For example, when the server 20 acquires work performance information from the work vehicle 10 and the portable operation terminal 40 after spraying work is carried out in each field F and stores the work history information, the control unit 31 stores the work history information. Based on this, recipe information is registered for each field F or each spraying operation. In this manner, one or a plurality of pieces of recipe information are associated with each field F and registered.

Also, the field manager can create a new recipe on the recipe information screen Dr. For example, on the recipe information screen Dr, the field manager can create a new recipe by pressing an add button to register chemicals and usage amounts, and pressing a setting button. The recipe information of the recipe selected by the field manager is associated with the field F and stored.

The creation processing unit 313 receives an operation of selecting recipe information (first recipe information of the present invention) scheduled to be used for the spraying work of the field F from among a plurality of pieces of recipe information, and creates a work plan based on the received recipe information. to create Specifically, when a predetermined recipe is selected on the recipe information screen Dr, the calculation processing unit 314 calculates the total amount of chemicals and the total amount of water based on the target route R of the field F and the recipe information. , the creation processing unit 313 creates a work plan including information on the calculated chemical and water application amounts.

In this way, the control unit 31 displays the amount of spraying and the spraying time corresponding to the field F calculated based on the work history information of the past spraying work of the field F. create a work plan; As a result, the field manager can grasp the application amount and the application time in advance and create a work plan. Therefore, it is possible to create an appropriate work plan corresponding to the field F on which the spraying work is to be carried out. In addition, spraying work can be carried out as planned in the created work plan. In addition, it is possible to prevent an inappropriate chemical from being sprayed on the field F.

Further, the control unit 31 displays the registered recipe information in a selectable manner on the registration screen D1, and based on the selected recipe information, decides the chemicals to be used for the spraying work in the field F and the spraying amount, and makes a work plan. to create As a result, the field manager can create a work plan suitable for the field F by a simple operation of selecting past recipe information.

By the way, there is a case where one working vehicle 10 carries out spraying work on a plurality of farm fields F consecutively on the same day. In this case, when the work plan is created, if the total application amount of chemicals necessary for a plurality of fields F can be grasped, the total application amount of the chemicals can be stored in the storage tank 14A before starting work. , the required replenishment amount of medicine can be appropriately replenished during work.

Therefore, as another embodiment, when creating a work plan corresponding to a plurality of fields F, the display processing unit 312 displays the spraying work required when performing the spraying work on the plurality of fields F collectively on the scheduled work date. The total amount may be displayed on the registration screen D1. For example, when creating a work plan for spraying work with a scheduled work date of “March 1” for fields A1 and A2, the display processing unit 312 determines the amount of spraying required for field A1 (the total amount of chemicals and water ) and the required application amount (total amount of chemicals and water) in the field A2 is displayed on the registration screen D1.

In addition, the creation processing unit 313 creates a work plan that summarizes the spraying work for each of the fields A1 and A2. For example, when the field manager selects fields A1 and A2 on the map Mp of the registration screen D1, the creation processing unit 313 creates one work plan that summarizes the spraying operations for the fields A1 and A2. Note that the control unit 31 performs the above process on the condition that the same chemicals are used in the agricultural field A1 and the agricultural field A2. As a result, the operator can store the total spray amount of chemicals required for the fields A1 and A2 in the storage tank 14A before starting the spraying operations for the fields A1 and A2. In addition, the operator stores the required spraying amount of the chemical in the storage tank 14A in the field A1 and performs the spraying operation on the field A1, and then replenishes the required spraying amount of the chemical in the field A2 and sprays the field A2. work can be done.

In this way, the control unit 31 calculates the spraying amount and the spraying time of the chemical agent based on the target route R of the work vehicle 10 performing spraying work in the field F, and manages the calculated spraying amount and the spraying time. Display it on the terminal 30 (see FIG. 9, etc.). Further, the control unit 31 creates a work plan for the spraying work corresponding to the field F based on the spraying amount and the spraying time.

The control unit 31 executes the following processes in addition to the above processes. For example, the control unit 31 receives from the worker a work start operation for causing the work vehicle 10 to start work, a travel stop operation for stopping travel of the work vehicle 10 during automatic travel, and the like. Upon receiving each operation, the control unit 31 outputs an instruction corresponding to each operation to the work vehicle 10 via the server 20 .

When the vehicle control device 11 of the work vehicle 10 acquires the work start instruction from the management operation terminal 30, the work vehicle 10 automatically starts running and work (for example, spraying work). Further, when the vehicle control device 11 acquires a travel stop instruction from the management operation terminal 30, the vehicle control device 11 stops the work vehicle 10 from automatically traveling and performing work.

Note that the management operation terminal 30 may be able to access the website of the agricultural support service (agricultural support site) provided by the server 20 via the communication network N1.

The work vehicle 10 automatically travels along the target route R while measuring the current position of the work vehicle 10 by the positioning device 16 .

Here, the work vehicle 10 is configured to automatically travel when the current position is within the field F, and when the current position is outside the field F (public road, etc.), the work vehicle 10 automatically travels. It is configured so that it cannot run. Further, the work vehicle 10 is configured to automatically travel when the current position matches the work start position S, for example.

When the current position of the work vehicle 10 coincides with the work start position S, when the operator presses the start button of the operation remote control (not shown) to give a work start instruction, the vehicle control device 11 automatically starts the work vehicle 10. The vehicle starts traveling and the spraying work by the spraying device 14 is started. That is, the work vehicle 10 permits automatic travel on the condition that the current position matches the work start position S. The conditions for permitting automatic travel of the work vehicle 10 are not limited to the above conditions.

The vehicle control device 11 automatically travels the work vehicle 10 from the work start position S to the work end position G based on the target route R acquired from the server 20 . Further, the vehicle control device 11 may automatically travel from the work end position G to the entrance of the field F when the work vehicle 10 finishes the work. When the work vehicle 10 is automatically traveling, the portable operation terminal 40 can receive the state of the work vehicle 10 (position, traveling speed, work status, etc.) from the work vehicle 10 and display it on the operation display unit 43. .

[Portable operation terminal 40]

The ROM is a non-volatile storage unit in which control programs such as BIOS and OS for causing the CPU to execute various arithmetic processes are stored in advance. The RAM is a volatile or nonvolatile storage unit that stores various information, and is used as a temporary storage memory (work area) for various processes executed by the CPU. The control unit 41 controls the server 20 by causing the CPU to execute various control programs pre-stored in the ROM or storage unit 42 .

Specifically, the control unit 41 acquires various information from the server 20 . For example, the control unit 41 acquires information on the work plan corresponding to the field F from the server 20 . After acquiring the work plan, the control unit 41 causes the portable operation terminal 40 to display the work information screen D11. For example, when a worker who owns the mobile operating terminal 40 enters a user ID and password on the login screen displayed on the mobile operating terminal 40, the control section 41 displays the work information screen D11.

FIG. 15 shows an example of the work information screen D11. For example, on the work information screen D11 shown in FIG. 15, date information (date selection icon) and a work plan corresponding to each of a plurality of fields F (fields A8, A11, A1, A12) in which worker P1 is in charge of work are displayed. A work information icon B1 shown is displayed. Warning information Bm is displayed on the work information icon B1 corresponding to the field A8. Also, the background image Ba of the work information icon B1 corresponding to the fields A8 and A11 is highlighted. For example, in the case where it is necessary to call attention in order to carry out the work as planned in the work plan in the fields A8 and A11, the control unit 41 displays the warning information Bm or highlights the background image Ba. do. Specifically, when the work is not completed on the scheduled work date in the field A8, the control unit 41 causes the work information icon B1 corresponding to the field A8 to display the warning information Bm, and highlights the background image Ba. . Further, when the field A11 is off-limits for a predetermined period after the spraying work is completed, the control unit 41 highlights the background image Ba of the work information icon B1 corresponding to the field A11.

In addition, the control unit 41 preferentially displays the work information icon B1 corresponding to the work plan requiring attention in order to carry out the work according to the plan of the work plan, at the top of the work information screen D11. Further, the control unit 41 continues to display the warning information Bm until the work on the field A8 is finished, for example. In addition, the control unit 41 highlights the background image Ba until, for example, the no-entry period of the agricultural field A11 ends.

In addition, the worker can select the field F to be worked on on the day (“March 5”) on the work information screen D11. For example, when the worker P1 selects the work information icon B1 for the field A1 on the work information screen D11, the control unit 41 displays the work plan screen D12 including the work plan for the field A1 corresponding to the selected work information icon B1. Let FIG. 16 shows an example of the work plan screen D12. The work plan screen D12 displays information about the work plan registered on the registration screen D1 (see FIG. 9). The worker P1 can confirm the work contents of the field A1 on the day (“March 5”) on the work plan screen D12.

Further, the worker P1 can change the work content on the work plan screen D12. For example, the worker P1 can change the work time, the work type (spraying, weeding, etc.), the amount of spraying, the model of the work vehicle 10, and the like.

FIG. 17 shows an example of the work status screen D13. The same information as the work status screen D3 (see FIG. 12) displayed on the management operation terminal 30 is displayed on the work status screen D13. The example shown in FIG. 17 indicates that the spraying work is currently being performed in fields A5 and A9.

Further, for example, when the work is interrupted and then restarted, the control unit 41 displays the restart position corresponding to the interrupted position on the work position screen D14. FIG. 18 shows an example of the work position screen D14. For example, in the field A5, when the work is interrupted and then restarted, the control unit 41 displays the restart position Sp at the interruption position of the field A5. As a result, the worker can move the work vehicle 10 to the restart position Sp and restart the work.

Further, the control unit 41 may receive a work end operation from the worker in the portable operation terminal 40 . For example, on the operation screen D15 shown in FIG. 19, when the worker presses the end button, the control unit 41 accepts the work end operation and outputs a work end instruction to the server 20 . When the server 20 acquires the work end instruction, it outputs a work stop instruction (stop signal) to the work vehicle 10 . When receiving the work stop instruction from the server 20, the vehicle control device 11 of the work vehicle 10 moves the work vehicle 10 to a predetermined position to stop automatic travel and work.

In addition, the control unit 41 receives an input operation such as a work record from the operator on the operation screen D15. The control part 41 outputs to the server 20, if input operation of a work performance is received. When the server 20 acquires the work record, it saves the work record as work history information.

[Work management processing]
An example of the work management process executed by the control unit 31 of the management operation terminal 30 will be described below with reference to FIGS. 20 and 21. FIG.

The present invention can be regarded as an invention of a work management method for executing one or more steps included in the work management process. Also, one or more steps included in the work management process described here may be omitted as appropriate. Note that the execution order of the steps in the work management process may differ as long as the same effects are produced. Furthermore, here, a case where the control unit 31 executes each step in the work management process will be described as an example, but one or more processors execute each step in the work management process in a distributed manner. are also contemplated as other embodiments.

FIG. 20 is a flow chart showing an example of a procedure for executing work plan creation processing for creating a work plan. FIG. 21 is a flow chart showing an example of a procedure for executing notification processing for notifying predetermined notification information when it is necessary to call attention in order to carry out the work as planned in the work plan. The work plan creation process and the notification process are included in the work management process.

[Work plan creation process]
An example of the work plan creation process executed by the control unit 31 of the management operation terminal 30 will be described with reference to FIG.

In step S1, the control unit 31 receives a selection operation of the farm field F from the farm manager. For example, when creating a work plan, the field manager logs in by entering the user ID and password on the login screen of the management operation terminal 30 . Then, the farm field manager selects the target farm field F on the registration screen D<b>1 (see FIG. 9 ) displayed on the management operation terminal 30 . Here, for example, the field manager selects field A1.

Next, in step S2, the control unit 31 generates a target route R. Specifically, the control unit 31 generates a target route R (see FIG. 8) for the selected farm field F based on the work vehicle information, the farm field information, the work information, and the like. Here, for example, the control unit 31 generates the target route R for the agricultural field A1.

Next, in step S3, the control unit 31 accepts an operation for registering various work information. Specifically, the field manager selects the scheduled work date, work time, work type, worker, and type of work vehicle 10 in the registration field R0 of the registration screen D1 (see FIG. 9). The control unit 31 receives a selection operation by the field manager. The control unit 31 registers various work information according to the selection operation.

Next, in step S4, based on the target route R, the control unit 31 calculates the spraying amount of the chemical agent and the spraying time of the spraying work. For example, the control unit 31 calculates the application time based on information such as the area of the agricultural field A1, the traveling speed of the work vehicle 10, the target route R, and the working machine. Further, the control unit 31 calculates the spraying time based on the work history information (see FIG. 13) of the past spraying work of the field A1.

Next, in step S5, the controller 31 displays the calculated spraying amount and spraying time on the registration screen D1 (see FIG. 9). Specifically, the control unit 31 displays the calculated application amount (the total amount of medicine and the total amount of water) in the medicine column R5 and the water content column R6 of the registration screen D1, and the calculated application time of the registration screen D1. It is displayed in the work time column R3.

Next, in step S6, the control unit 31 determines whether or not a recipe selection operation has been received. For example, when selecting a recipe registered based on the work history information (see FIG. 13), the field manager selects the icon in the chemical column R5 of the registration screen D1. The field manager selects a desired recipe from one or a plurality of recipes on the recipe information screen Dr (see FIG. 14). When the field manager selects a recipe (S6: Yes), the controller 31 shifts the process to step S7. On the other hand, when the field manager does not select a recipe (S6: No), the control unit 31 shifts the process to step S8.

In step S7, the controller 31 changes the application amount according to the selected recipe. Specifically, the control unit 31 calculates the application amount based on the selected recipe, and changes the application amount calculated in step S4. Note that when the spraying time is changed by selecting a recipe, the control unit 31 also changes the spraying time accordingly. The control unit 31 updates the information in the drug column R5, the water column R6, and the work time column R3.

In step S8, the control unit 31 creates a work plan. Specifically, the control unit 31 creates a work plan for the field F based on the work information registered by each of the processes described above. Here, the control unit 31 creates a work plan including work information (each information of items R1 to R8) related to work to be performed in the field A1 on "March 1".

The control unit 31 executes the work plan creation process as described above. Further, the control unit 31 executes the work plan creation process for each field F. FIG. The control unit 31 also outputs data of the created work plan to the server 20 . The data of the target route R may be included in the work plan. The server 20 saves and manages the work plan and the target route R for each field F.

As another embodiment, the control unit 31 may accept a recipe selection operation after step S3. For example, upon receiving a recipe selection operation, the control unit 31 may calculate and display the application amount and the application time based on the selected recipe, and create a work plan.

Further, as another embodiment, the control unit 41 of the portable operation terminal 40 may execute the work plan creation process according to the login operation of the worker.

[Notification process]
An example of the notification process executed by the control unit 31 of the management operation terminal 30 will be described with reference to FIG.

In step S11, the control unit 31 acquires a work plan. For example, the control unit 31 acquires multiple work plans stored in the server 20 . Specifically, when the field manager logs in by entering a user ID and a password in the login screen of the management operation terminal 30, the control section 31 acquires the latest work plan at that time. The server 20 acquires work results from the work vehicle 10 and the portable operation terminal 40, and stores the work results as work history information in association with the target work plan.

Next, in step S12, the control unit 31 selects among the acquired work plans a work plan (a first work plan of the present invention) that requires attention so that the work vehicle 10 can perform the work as planned in the work plan. ) exists. Specific examples are shown below.

As a first example, the control unit 31 determines whether or not there is a work plan for which work has not been completed at present among the plurality of work plans. Specifically, the control unit 31 refers to the work history information, and at the time of “March 5”, the scheduled work date before “March 5” is registered and the work is completed. It is determined whether or not there is a work plan that has not been executed. For example, when the worker fails to complete the work on the scheduled work date or forgets to do the work, information indicating that the work has not been completed is registered in the work history information.

As a second example, the control unit 31 determines whether or not there is a work plan for which a predetermined number of days or more have passed from the work date on which the previous work was performed to the current date, among the plurality of work plans. Specifically, the control unit 31 refers to the work history information, and as of "March 5", there is a work plan in which "five days" or more have passed since the work date of the previous spraying work. Determine whether or not Incidentally, the predetermined number of days is set by the operation of the elapsed days button K3 (see FIG. 10) by the field manager.

As a third example, the control unit 31 determines whether or not there is a work plan whose work content is work that is repeatedly performed at a predetermined cycle and whose scheduled work date is not registered at a predetermined cycle. . Specifically, the control unit 31 selects a plurality of work plans in which the work content is a spraying work that is repeatedly performed at a predetermined cycle (for example, one week or two weeks), and the scheduled work date is the predetermined work schedule. Determine whether or not there is a work plan that has not been registered in the cycle.

As a fourth example, the control unit 31 determines whether or not there is a work plan in which the weather forecast for the scheduled work date is predicted to be rainy, among the plurality of work plans.

As a fifth example, the control unit 31 determines that, among the plurality of work plans, there is a work plan in which entry to the field F is prohibited for a predetermined period after the work vehicle 10 performs the work. Determine if it exists.

When the determination result in the determination process of each example described above is affirmative, that is, there is a work plan that requires attention so that the work vehicle 10 can perform the work as planned in the work plan among the plurality of work plans. If it exists (S12: Yes), the control unit 31 shifts the process to step S13. On the other hand, if the determination result is negative in the determination processing of each of the examples described above, that is, if there are a plurality of work plans, the work vehicle 10 needs to call attention to perform the work as planned in the work plan. If there is no plan (S12: No), the control unit 31 terminates the notification process.

In step S13, the control unit 31 executes notification processing for notifying predetermined notification information. Specific examples of notification processing corresponding to specific examples of the determination processing described above (first example to fifth example) are shown below.

In the case of the first example, the control unit 31 causes the field F corresponding to the work plan to be identifiably displayed on the map Mp of the registration screen D1 shown in FIG. For example, in the case where a work plan is registered with "March 3" as the scheduled work date of the spraying work for the field A6, the control unit 31 changes the background image Fs of the field A6 to The field A6 is identifiably displayed by highlighting it. As another embodiment, the control unit 31 may display a flag on the agricultural field A6.

Further, the control unit 31 causes the field F corresponding to the work plan to be identifiably displayed in the schedule table Sd shown in FIG. 11 . For example, if a work plan is registered with "March 3" as the scheduled work date of the spraying work for the field A6, the control unit 31, as shown in FIG. The warning information Cm is displayed in the date column of "day", and the background image of the date column is highlighted. In addition, the control unit 31 highlights the background image Fm of the name of the field A6 in the schedule Sd.

In the case of the second example, the control unit 31 displays the elapsed days from the date of the previous work to the current date in association with the field F on the map Mp of the registration screen D1 shown in FIG. For example, when 5 days have passed since the last spraying work day for the field A3, the control unit 31 displays a days flag Fg indicating that 5 days have passed in association with the field A3. In the example shown in FIG. 10, fields A7 and A9 indicate that 6 days have passed since the last spraying work day, and field A10 has passed 7 days since the last spraying work day. It represents that.

In addition, the control unit 31 causes the number of days elapsed from the previous work day to the current day to be displayed in association with the field F in the schedule table Sd of the schedule screen D2 shown in FIG. 11 (not shown).

In the case of the third example, the control unit 31 performs the spraying work one week before the current date "March 5" when it is necessary to carry out the spraying work every week in the field A8, for example. and the work plan for the spraying work is not registered on the current day, the field A8 is identifiably displayed on the map Mp. Further, the control unit 31 may display information prompting registration of the work plan for the field A8.

Further, the control unit 31 causes the field A8 corresponding to the work plan to be displayed in a identifiable manner in the schedule table Sd of the schedule screen D2 (not shown).

In the case of the fourth example, when there is a work plan in which the weather forecast for the scheduled work day is rainy, the control unit 31 determines the predetermined work that needs to be performed after the rain. When the scheduled work date of the content is not registered, the farm field F corresponding to the work plan is identifiably displayed on the map Mp of the registration screen D1. For example, in the field A12, if it rained immediately after the spraying work was carried out on "March 4th", and if the work plan for the spraying work is not registered for the next day "March 5th", the control unit 31 displays the field A12 in a identifiable manner on the registration screen D1 of "March 5". Note that the notification processing unit 316 may display information prompting registration of the work plan for the spraying work for the field A12.

Further, the control unit 31 causes the field F corresponding to the work plan to be identifiably displayed in the schedule table Sd of the schedule screen D2.

In the case of the fifth example, the control unit 31 identifiably displays that the field F corresponding to the work plan is off-limits for a predetermined period on the map Mp of the registration screen D1. For example, if 48 hours have not passed since the spraying work was performed on the fields A2, A4, and A11, the control unit 31 highlights the background image Ft of each of the fields A2, A4, and A11. to display each field in an identifiable manner.

In addition, the control unit 31 causes the schedule table Sd of the schedule screen D2 to identifiably display that the field F corresponding to the work plan is off-limits for a predetermined period. For example, if 48 hours have not passed since the spraying work was performed on the fields A2 and A4, the control unit 31 displays the background images C2 of the fields A2 and A4 in the schedule Sd of the schedule screen D2. are highlighted so that each field can be identified (see FIG. 11). In addition, the control unit 31 may display the period of no-entry in the past dates, such as the field A1 and the field A5, or display the period of no-entry after the current date (future), such as the field A5. A period may be displayed.

After the process of step S13, the control unit 31 terminates the notification process. The control unit 31 executes the notification process every time a field manager logs in and accesses the registration screen D1.

As another embodiment, the control unit 41 of the portable operation terminal 40 may execute the notification process according to the operator's login operation. In this case, the control unit 41 causes the portable operation terminal 40 to display the notification information.

If the first work plan exists among the plurality of work plans, work information relating to the first work plan is notified.

According to the above configuration, for example, a work plan in which work has not been completed on the registered scheduled work date (the first example), a work plan in which a predetermined number of days or more have elapsed from the work date on which the work was performed to the current date (the second example), a work plan in which the scheduled work date is not registered at a predetermined cycle (the third example), and a work plan in which the weather forecast for the scheduled work date is predicted to be rainy (the fourth example) ), a work plan for a field F that is off-limits for a predetermined period (fifth example), etc. (first work plan ) exists, the field manager, the worker, etc. can be notified of the predetermined notification information. Therefore, field managers, workers, and the like can grasp work that is not progressing as planned in the work plan, work that requires attention, and the like. That is, it is possible to call attention to the work plan to the field manager, workers, and the like. As a result, it becomes possible for the worker to grasp the work situation according to the work plan. Then, it becomes possible to appropriately carry out the work in each field F according to the work plan.

Further, the automatic traveling system 1 according to the present embodiment, based on the target route R of the work vehicle 10 that performs the spraying work on the spraying target placed in the field F, the spraying amount of the spraying material to the spraying target and the spraying time of the spraying work are calculated, and the spraying amount and the spraying time are displayed on the operation terminal (management operation terminal 30, portable operation terminal 40, etc.). Further, the automatic traveling system 1 creates a work plan for the spraying work corresponding to the field F based on the spraying amount and the spraying time.

According to the above configuration, the field manager can grasp the application amount and application time of the chemical when creating a work plan for the application work of the field F. Therefore, it is possible to create an appropriate work plan corresponding to the field F on which the spraying work is to be carried out. Therefore, the spraying work can be carried out as planned in the created work plan. In addition, it is possible to prevent an inappropriate chemical from being sprayed on the field F.

In the above-described embodiment, the automatic driving system 1 corresponds to the work management system according to the present invention, but the work management system according to the present invention may be configured by the management operation terminal 30 alone. Also, the work management system according to the present invention may be configured by the server 20 alone or the portable operation terminal 40 alone. For example, the server 20 may include the calculation processing unit 314 , determination processing unit 315 , and notification processing unit 316 of the management operation terminal 30 . Also, the portable operation terminal 40 may include the setting processing unit 311 , the display processing unit 312 , the creation processing unit 313 , the calculation processing unit 314 , the determination processing unit 315 , and the notification processing unit 316 of the management operation terminal 30 .
