Description

[Technical field]

[0001] The present invention relates to a work management method, a work management system, and a work management program. [Background technology]

[0002] The amount of work required for harvesting agricultural products varies depending on the weather. For example, at a collection site for harvested agricultural products, workers who harvest the agricultural products may adjust the amount of harvested products brought in so that the ideal amount is brought in. Patent Document 1 discloses a technology that estimates the amount of harvested products by comparing the amount of harvested products brought in to the collection site at a certain point in the collection period, for example at a certain point in a day, with the change in the ideal amount of harvested products. For example, when it is estimated that the amount of harvested products will be insufficient, this technology notifies the producer of that fact and encourages the producer to harvest the agricultural products and bring them to the collection site.

[0015] (Embodiment 1) A work management system 1000 according to this embodiment of the present invention will be described with reference to the drawings. In this embodiment, as shown in Fig. 1, the work management system 1000 includes a work management device 100 and a terminal 200. The work management device 100 is communicatively connected to the terminal 200 and at least one or more work devices 30 via a network 20, for example, the Internet.

[0016] The working device 30 performs agricultural work by moving within the field. The work management device 100 acquires operation information in the field from at least one or more working devices 30, and stores agricultural data 300 indicating the work area, planting amount, amount of pesticide applied, harvest amount, etc. based on the acquired operation information. The working device 30 includes, for example, a tractor, a rice planting machine, a harvester such as a combine, and a sprayer that sprays pesticides such as a drone. The working device 30 may also include a transport vehicle that transports harvested products, materials, etc.

[0017] The operation information includes information that indicates the state of the working implement 30 when work is being performed in the field, such as information that indicates the speed, steering angle, engine RPM, ON / OFF status of various clutches, and position information of the working implement 30 at each time. When the working implement 30 is a vehicle that tows a work machine, such as a tractor, the operation information may also include information such as the PTO (power take-off) RPM when transmitting power to the work machine, and the hitch height and lift arm angle that indicate the attitude of the work machine.

[0018] In response to a request from terminal 200, work management device 100 calculates an estimated completion time when the work will be completed, and outputs an estimated completion signal indicating the calculated estimated completion time. Terminal 200 displays information indicating the estimated completion time based on the output estimated completion signal. For example, terminal 200 displays work management image 500 having estimated date display area 580 as shown in Fig. 2. Terminal 200 displays the estimated completion time as the estimated completion date in estimated date display area 580.

[0019] In this way, the work management system 1000 displays the estimated date when the work will be completed. The user can check the work management image 500 on the terminal 200 to know the estimated date when the work will be completed and manage the progress of the work.

[0020] The work management image 500 also displays the relationship between the amount of work 501 and the date 502 as the progress of the work. For example, when displaying the progress of work to harvest crops, the amount of work 501 represents the area where the crops have been harvested. The terminal 200 displays the amount of work performed up to now 510 and the current time 515 representing the current date, and displays the current progress status. The work management image 500 also displays the total amount of work 550 representing the total amount of work to be harvested, for example, the area of ​​the area to be harvested. The work management image 500 displays the estimated amount of progress 520 if the work is carried out at the current progress rate, and the estimated completion date 525 estimated when the work is completed. Furthermore, the terminal 200 displays the ratio of sunny days to rainy days since the start of the work in a rain frequency display area 570 provided in the work management image 500. This allows the user to grasp the progress status of the work.

[0021] (Work management system configuration) The configuration of the work management device 100 included in the work management system 1000 will be described. As shown in FIG. 1, the work management device 100 includes an input / output device 110, a calculation device 120, a communication device 130, and a storage device 140. The work management device 100 is, for example, a computer. Information for the calculation device 120 to execute processing is input to the input / output device 110. The input / output device 110 outputs the results of the processing executed by the calculation device 120. The input / output device 110 includes various input devices and output devices, for example, a keyboard, a mouse, a microphone, a display, a speaker, a touch panel, and the like. The input / output device 110 may be omitted.

[0022] The communication device 130 is electrically connected to the network 20 and communicates with each device via the network 20. The communication device 130 transfers operation information acquired from the maintenance device 30 to the arithmetic device 120. The communication device 130 also transfers signals generated by the arithmetic device 120 to the terminal 200. The communication device 130 includes various interfaces, such as a network interface card (NIC) and a universal serial bus (USB).

[0023] The storage device 140 stores various data for calculating the progress status, for example an estimated completion time for the work, such as agricultural data 300, and the work management program 310. The storage device 140 is used as a non-transitory tangible storage medium for storing the work management program 310. The work management program 310 may be provided as a computer program product recorded on a computer-readable storage medium 1, or may be provided as a computer program product downloadable from a server.

[0024] The agricultural data 300 includes operation information acquired from the working device 30 and evaluation information calculated based on the operation information. The operation information includes, for example, position information of the working device 30 at each time. The position information of the working device 30 is acquired by a positioning device provided on the working device 30, for example, a receiver of a Global Navigation Satellite System (GNSS). The operation information also includes the planting amount, the amount of pesticide applied, the harvest amount, etc., associated with the position information.

[0025] The evaluation information includes the work area, the harvest amount per unit area, the amount of pesticides and fertilizers sprayed per unit area, the amount of crops planted, the amount of seeds sown, etc. For example, the work area where the work device 30 has performed work is calculated from the position information of the work device 30.

[0026] The agricultural data 300 further includes information about the field on which the work is to be performed by the work implement 30. For example, the agricultural data 300 includes the area of ​​the field on which the work is to be performed.

[0027] The computing device 120 reads out and executes the task management program 310 from the storage device 140, and performs various data processing to calculate the progress status, for example, the estimated completion time of the task. For example, the computing device 120 includes a central processing unit (CPU) and the like.

[0028] The calculation device 120 reads and executes the work management program 310, thereby realizing a data storage unit 150, a work efficiency calculation unit 160, an estimation unit 170, and an output unit 180, as shown in Fig. 3. The data storage unit 150 stores agricultural data 300. The work efficiency calculation unit 160 calculates the work efficiency representing the amount of work per unit time based on the agricultural data 300. The estimation unit 170 calculates the progress status, for example, an estimated completion time, based on the calculated work efficiency and the work area of ​​the area to be worked on. The output unit 180 outputs a progress signal representing the calculated progress status, for example, an estimated completion signal.

[0029] Next, the configuration of the terminal 200 will be described. As shown in FIG. 1, the terminal 200 includes an input / output device 210, a calculation device 220, a communication device 230, and a storage device 240. The terminal 200 includes, for example, a computer, a tablet, a mobile phone, and the like. Information for the calculation device 220 to execute processing is input to the input / output device 210. In addition, the input / output device 210 outputs the result of the calculation device 220 executing the processing. The input / output device 210 includes various input devices and output devices, and includes, for example, a keyboard, a mouse, a microphone, a display, a speaker, a touch panel, and the like.

[0030] The communication device 230 is electrically connected to the network 20 and communicates with each device via the network 20. The communication device 230 transfers information acquired from the work management device 100 to the calculation device 220. The communication device 230 also transfers signals generated by the calculation device 220 to the work management device 100. The communication device 230 includes various interfaces, such as a network interface card (NIC) and a universal serial bus (USB).

[0031] The storage device 240 stores various data, such as a display program 320, for displaying the progress status, for example, an estimated completion time of the task, on the input / output device 210 of the terminal 200. The storage device 240 is used as a non-transitory tangible storage medium for storing the display program 320. The display program 320 may be provided as a computer program product recorded in a computer-readable storage medium 2, or may be provided as a computer program product downloadable from a server. The display program 320 may be provided by being recorded in the storage medium 1.

[0032] The arithmetic device 220 reads and executes the display program 320 to perform various data processing for displaying the progress status, for example, the estimated completion time of the work, acquired from the work management device 100. The arithmetic device 220 includes, for example, a central processing unit (CPU) and the like.

[0033] When the arithmetic device 220 reads and executes the display program 320, it cooperates with the input / output device 210 to realize the display unit 250 as shown in Fig. 3. The display unit 250 acquires the progress status from the task management device 100, and displays a task management image 500 indicating the progress status.

[0034] (Operation of the work management system) 1, when it is stopped, for example, when the engine is stopped, it transmits operation information to the work management apparatus 100. When the work device 30 is operating, it may successively transmit operation information to the work management apparatus 100.

[0035] When the arithmetic device 120 of the work management apparatus 100 receives operation information from the work apparatus 30, it reads and executes the work management program 310 and starts the process shown in Fig. 4, which is a work management method. The received operation information is stored in agricultural data 300 by the data storage unit 150 realized by the arithmetic device 120.

[0036] In step S110, the work efficiency calculation unit 160 realized by the arithmetic device 120 calculates work efficiency that indicates the amount of work per unit time based on the operation information. For example, the work efficiency calculation unit 160 calculates work efficiency according to the amount of precipitation based on the amount of precipitation in an area including the field where the work was performed and the operation information.

[0037] First, the work efficiency calculation unit 160 obtains the amount of precipitation in the area including the field where the work was performed, including the day on which the work was performed. The amount of precipitation may be obtained from a weather information server not included in the work management system 1000, or may be input by the user to the input / output device 210 of the terminal 200.

[0038] Next, the work efficiency calculation unit 160 classifies the work day on which the work device 30 performed the work into a plurality of precipitation states according to the acquired precipitation amount. For example, the work efficiency calculation unit 160 classifies a day on which the precipitation amount is less than a threshold as a sunny day, and classifies a day on which the precipitation amount is equal to or greater than the threshold as a rainy day. The work efficiency calculation unit 160 may set two or more thresholds and classify the work day into three or more precipitation states. In addition, the precipitation states may be classified based on the amount of precipitation for a predetermined period prior to the work day.

[0039] Next, the work efficiency calculation unit 160 calculates the work efficiency for each classified precipitation condition. For example, the work efficiency calculation unit 160 calculates the amount of work harvested by at least one or more work devices 30, for example, the total work area representing the harvested area, for each precipitation condition. The work efficiency calculation unit 160 also calculates the total work time representing the time required for harvesting, for each precipitation condition. The work efficiency calculation unit 160 calculates the work efficiency representing the amount of work per unit time by dividing the calculated total amount of work by the total work time, for each precipitation condition.

[0040] In step S120, the estimation unit 170 estimates an estimated completion time when the work will be completed based on the calculated work efficiency and a total work amount 550 to be performed by at least one work device 30. For example, the estimation unit 170 estimates the estimated completion time based on a state frequency indicating the rate at which it rains in an area including the field where the work is performed, the work efficiency, and the total work amount 550. When multiple work devices 30 are performing work, the total work amount 550 indicates the sum of the work amounts to be performed by each of the work devices 30.

[0041] First, the estimation unit 170 calculates the state frequency in an area including the field where the work is performed. For example, the estimation unit 170 calculates the ratio of the number of days in each precipitation state to the number of days on which the work device 30 performed work as the state frequency based on the operation information. For example, when there were 5 rainy days out of 20 days on which the work device 30 performed work, the estimation unit 170 calculates the state frequency representing rainy days as 25%. Furthermore, when there were 15 sunny days out of 20 days on which the work device 30 performed work, the estimation unit 170 calculates the state frequency representing sunny days as 75%.

[0042] Next, the estimation unit 170 acquires a total amount of work 550 that should be performed by the task device 30. The total amount of work 550 is stored in the agricultural data 300, for example.

[0043] Next, the estimation unit 170 calculates the date on which a total amount of work of 550 will be completed when work is performed in an area where each precipitation state occurs with a probability represented by the calculated state frequency, with the work efficiency for each calculated precipitation state. For example, the estimation unit 170 calculates the number of work days x that satisfies formula (1).

number

[0044] Finally, the estimation unit 170 adds the calculated number of work days x to the current date to calculate the estimated completion time.

[0045] In step S130, the output unit 180 outputs an estimated completion signal representing the calculated estimated completion time. The estimated completion signal includes a signal representing the work management image 500 shown in Fig. 2 in addition to the estimated completion time. The output unit 180 generates an estimated completion signal representing each piece of information included in the work management image 500. The output unit 180 may also generate image data representing the work management image 500 and generate an estimated completion signal representing the generated image data.

[0046] 4, the display unit 250 implemented by the computing device 220 of the terminal 200 displays a task management image 500 including an estimated completion time based on the estimated completion signal. By checking the task management image 500, the user can grasp the estimated completion date when the task will be completed and manage the progress of the task.

[0047] (Embodiment 2) Furthermore, the work management system 1000 may notify the user of the target efficiency for completing the work on the target completion date input by the user. The target efficiency indicates the target amount of work to be done per unit time, for example, per day. For example, the terminal 200 displays a work management image 500 including a target efficiency display area 590 as shown in Fig. 5. The target efficiency display area 590 displays the target efficiency for each precipitation condition.

[0048] The work management image 500 also displays a target progress amount 530 and a target completion date 535 when the work is performed at the target efficiency. The work management image 500 may also display a limit work amount 560. The limit work amount 560 represents the maximum amount of work that can be handled by work performed before or after the work. When representing work of harvesting crops, for example, the limit work amount 560 represents the progress amount according to the harvest amount that can be harvested and then dried. When the harvested product is sugarcane, the harvest work may represent sugar processing at a sugar factory. For example, when the maximum yield that can be processed in the harvest work is 900 tons per day and the harvest amount is 0.4 tons per 1a, the estimation unit 170 calculates that the limit work amount 560 is 2250a per day.

[0049] The configuration of the work management system 1000 is similar to that of the first embodiment, and therefore a description thereof will be omitted.

[0050] (Operation of the work management system) When arithmetic device 120 of task management apparatus 100 receives operation information from task device 30, it reads and executes task management program 310 to start the process shown in Fig. 6 which is a task management method. In step S210, estimation unit 170 realized by arithmetic device 120 acquires a target completion time. For example, estimation unit 170 acquires a pre-registered target management time from storage device 140. Furthermore, estimation unit 170 may receive from display unit 250 the target completion time that the user inputs to input / output device 210 of terminal 200.

[0051] In step S220, the work efficiency calculation unit 160 calculates the ratio of the work efficiency in two precipitation conditions obtained by classifying the work day by the amount of precipitation. For example, the work efficiency calculation unit 160 calculates the work efficiency according to the amount of precipitation based on the amount of precipitation in the area including the field and the operation information. Based on the calculated work efficiency, the work efficiency calculation unit 160 calculates the ratio of the work efficiency in two precipitation conditions obtained by classifying the work day by the amount of precipitation.

[0052] First, the work efficiency calculation unit 160 calculates the work efficiency in the same manner as in step S110 shown in FIG. 4 of the first embodiment. Specifically, the work efficiency calculation unit 160 acquires the amount of precipitation in an area including the field on which the work was performed, including the day on which the work was performed. The work day on which the work device 30 performed the work is classified into a plurality of precipitation conditions according to the acquired amount of precipitation. The work efficiency calculation unit 160 calculates the total amount of work and the total amount of work time for each classified precipitation condition, and calculates the work efficiency by dividing the calculated total amount of work by the total amount of work time.

[0053] Next, the work efficiency calculation unit 160 calculates the ratio of work efficiency for a combination of two precipitation conditions. For example, when a work day is classified into two precipitation conditions (e.g., sunny days and rainy days), the work efficiency calculation unit 160 calculates the ratio of work efficiency on rainy days to work efficiency on sunny days. When a work day is classified into three or more precipitation conditions, the work efficiency calculation unit 160 sets the work efficiency in one precipitation condition as a standard work efficiency and calculates the ratio of the work efficiency of each precipitation condition to the standard work efficiency. Therefore, the work efficiency of each precipitation condition is expressed as a ratio to the standard work efficiency.

[0054] 6, the estimation unit 170 estimates a target efficiency that represents a target amount of work per unit time in each precipitation state, based on the calculated work efficiency ratio, the target completion time, and the total amount of work 550 to be performed by the work implement 30. For example, the estimation unit 170 estimates the target efficiency based on a state frequency that represents the proportion of rain that falls in an area that includes the field where the work is performed, the ratio, the target completion time, and the total amount of work 550.

[0055] First, the estimation unit 170 calculates the condition frequency in the area including the farm field where the work is to be performed. The method of calculating the condition frequency is similar to that of step S120 shown in Fig. 4, and therefore a detailed description thereof will be omitted.

[0056] Next, the estimation unit 170 acquires a total amount of work 550 that should be performed by the task device 30. The total amount of work 550 is stored in the agricultural data 300, for example.

[0057] Next, the estimation unit 170 calculates a target efficiency for completing the total work amount of 550 by the target completion time when the work is performed in an area where each precipitation state occurs with a probability represented by the calculated state frequency so that the work efficiency in each precipitation state is the calculated ratio. For example, the estimation unit 170 calculates a standard work efficiency α b Calculate α b represents the work efficiency of one of the one or more work implements 30 in a given precipitation condition, for example.

number

[0058] Finally, the estimation unit 170 estimates the calculated standard work efficiency α b , the ratio γ of the working efficiency of the working implement 30 in the corresponding precipitation condition i,j The target efficiency, which represents the target amount of work per unit time in each precipitation condition, is calculated by integrating the above.

[0059] In step S240, the output unit 180 outputs a target signal representing the calculated target amount of work. The target signal includes a signal representing the task management image 500 shown in Fig. 5 in addition to the target amount of work per unit time. The output unit 180 generates an estimated completion signal representing each piece of information included in the task management image 500. The output unit 180 may also generate image data representing the task management image 500 and generate an estimated completion signal representing the generated image data.

[0060] In step S250 shown in Fig. 6, the display unit 250 realized by the arithmetic device 220 of the terminal 200 displays a work management image 500 including a target efficiency display area 590, as shown in Fig. 5, based on the target signal. By checking the work management image 500, the user can grasp the target amount of work to be completed by the target completion time, and manage the progress of the work.

[0061] (Modification) The configuration described in the embodiment is merely an example, and the configuration can be changed as long as the function is not impaired. For example, the estimation unit 170 may estimate the target efficiency, which indicates the target amount of work per unit time, to be equal to or less than the limit amount of work 560, which indicates the maximum amount of work that can be handled by work performed before or after the work. When the target efficiencies for multiple precipitation conditions include a target efficiency that is greater than the limit amount of work 560, the estimation unit 170 fixes this target efficiency to the limit amount of work 560 and estimates the reference work efficiency α b For example, the estimation unit 170 calculates a standard work efficiency α b Calculate.

number

[0062] The estimation unit 170 calculates a target efficiency that is less than the limit work amount 560 as a reference work efficiency α max and the ratio γ i,j and calculates a target efficiency that is equal to or greater than the limit workload 560 as the limit workload 560. In this way, the estimation unit 170 calculates a target efficiency that is equal to or less than the limit workload 560. This reduces the possibility that the work management system 1000 calculates a target workload that cannot be processed by work performed before or after the work.

[0063] The estimation unit 170 may estimate the target efficiency to be equal to or less than a threshold value that is smaller than the limit workload 560. In this case, the ... max is set as the threshold, and the standard work efficiency α b In this way, the work management system 1000 reduces the possibility of calculating a target work amount that cannot be processed by work performed before or after the work.

[0064] This limit work amount 560 may be calculated by any method. For example, the limit work amount 560 may be calculated based on the harvest amount per unit area input by the user to the input / output device 210 and the harvest amount that can be handled by work performed before or after the work. For example, the estimation unit 170 acquires the input harvest amount per unit area and the processable harvest amount from the display unit 250 of the terminal 200. The harvest amount per unit area may also be calculated based on the operation information. The data storage unit 150 acquires the area on which the work device 30 performed the work and the harvest amount harvested by the work device 30 from the operation information. The data storage unit 150 calculates the harvest amount per unit area based on the acquired area and harvest amount.

[0065] The state frequency, which indicates the proportion of work days belonging to each precipitation state, may be determined by any method, not limited to the method of determining it by the proportion of work days on which work has been performed up to the present time. For example, the state frequency may be determined according to an input by the user to the input / output device 210 of the terminal 200. For example, the user inputs an operation of moving the slider 575 of the rainy weather frequency display area 570 shown in FIG. 2 or FIG. 5 to the input / output device 210 to the left and right. The display unit 250 of the terminal 200 shown in FIG. 3 specifies the state frequency based on the input operation by the user, and outputs a signal representing the specified state frequency to the estimation unit 170 of the work management device 100. The estimation unit 170 estimates the progress status, for example, the estimated completion time or the target efficiency, using the state frequency acquired from the display unit 250. The output unit 180 outputs a progress signal, for example, an estimated completion signal or a target signal, representing the estimated progress status.

[0066] The work efficiency calculation unit 160 may express the work efficiency according to the amount of precipitation in any manner. For example, the work efficiency calculation unit 160 calculates a function for calculating the amount of work relative to the amount of precipitation based on the operation information and the weather information. For example, this function is an approximation curve that represents the relationship between the amount of precipitation and the amount of work. In this case, the estimation unit 170 estimates the estimated completion time based on the distribution of precipitation in the area including the field where the work is performed, the function for calculating the amount of work relative to the amount of precipitation, and the total amount of work 550.

[0067] The work efficiency calculation unit 160 may also express the ratio of the target efficiency according to the amount of precipitation in any manner. For example, the work efficiency calculation unit 160 calculates a function for calculating the amount of work for the amount of precipitation based on the operation information and the weather information. The estimation unit 170 estimates the target efficiency based on the distribution of precipitation in an area including the field where the work is performed, the function for calculating the amount of work for the amount of precipitation, the total amount of work 550, and the target completion time. For example, the estimation unit 170 calculates the amount of work that will be completed by the target completion time when the work device 30 performs the work with the amount of work for the amount of precipitation based on the distribution of precipitation in an area including the field where the work is performed and the function for calculating the amount of work for the amount of precipitation. The estimation unit 170 calculates the target efficiency by multiplying the ratio of the total amount of work 550 to the amount of work that will be completed by the target completion time by the amount of work for the amount of precipitation.

[0068] The display unit 250 may display information about each of the work devices 30 in a distinguishable manner on the work management image 500 shown in FIG. 2 or FIG. 5. For example, the display unit 250 may display a work management image 500 for each of the work devices 30, or may display a work performance amount 510, an estimated progress amount 520, a target progress amount 530, etc. for each of the work devices 30 on one work management image 500. This allows a user, for example, an owner of a field, to grasp the progress status of each work device 30 and change the field to which the work device 30 is assigned. The display unit 250 may also display information about each of the fields in a distinguishable manner on the work management image 500 shown in FIG. 2 or FIG. 5. In this case, the target work amount for each work device 30 is calculated based on the standard work efficiency α b to the ratio γ i,j It is calculated by accumulating the above.

[0069] Furthermore, the work efficiency calculation unit 160 and the estimation unit 170 may calculate the work efficiency, the estimated completion time, the target efficiency, and the like, without classifying into precipitation states. In this case, the work efficiency calculation unit 160 calculates the work efficiency representing the amount of work per unit time based on the operation information in step S110 shown in FIG. 4. Furthermore, the work efficiency calculation unit 160 omits the process of step S220 shown in FIG. 6. The estimation unit 170 estimates the target efficiency representing the target amount of work to be done per unit time based on the target completion time and the total amount of work 550 in step S230 shown in FIG. 6.

[0070] The estimated completion time is not limited to the day the work is completed, and may represent any time, such as the week the work is completed. Furthermore, the work efficiency represents the amount of work per unit time, and the unit time may represent any period, such as one day or one week. The amount of work is not limited to the work area, and may represent any value representing the progress of the work, such as the planting amount.

[0071] The above-described embodiment and modified examples are merely examples, and the configurations described in each embodiment and modified example may be arbitrarily changed or / and arbitrarily combined as long as the functions are not impaired. Furthermore, some of the functions described in the embodiment and modified examples may be omitted as long as the necessary functions can be realized. For example, the work efficiency calculation unit 160, the estimation unit 170, and the output unit 180 may be executed by the terminal 200. In this case, the terminal 200 acquires agricultural data 300 from the data storage unit 150 of the work management device 100. The work efficiency calculation unit 160 realized by the terminal 200 calculates the work efficiency or the ratio of the work efficiency. The estimation unit 170 of the terminal 200 estimates the estimated completion time or the target efficiency based on the work efficiency or the ratio of the work efficiency. The output unit 180 outputs a signal representing the estimated estimated completion time or the target efficiency to the display unit 250. The display unit 250 displays the estimated completion time or the target efficiency. In addition, a part or all of the work management device 100 may be executed by the terminal 200.
