Description

[Technical Field]

[0001] This invention relates to an agricultural work management support system and an agricultural work management support program. [Background technology]

[0002] For example, in the work management system disclosed in Patent Document 1, multiple identification media (referred to as "work content recognition tags" in the document) with different data contents are installed within the same area. A farm worker (referred to as "worker" in the document) selects an identification media corresponding to the work performed by the farm worker within that area and has a communication terminal (referred to as "mobile terminal device" in the document) read the data from the selected identification media. As a result, management data regarding the content of the farm work is transmitted to the server, and the work history is managed. [Prior art documents] [Patent Documents]

[0003] [Patent Document 1] Patent No. 6656634 [Overview of the Initiative] [Problems that the invention aims to solve]

[0004] In recent years, due to factors such as a shortage of farmers, agricultural corporations have emerged that operate on a large scale with a small number of people. Such agricultural corporations are required to operate efficiently with a limited number of people. For efficient operation, for example, managers or operators assign assigned farmers to designated areas in the field and periodically check the status of farm work in those areas. In this case, if farmers perform a reading operation where they select one of several identification media according to the task, as disclosed in Patent Document 1, each time they perform farm work, they may select the wrong identification media. This could make it difficult for managers or operators to accurately manage work history. Furthermore, in order to provide multiple identification media according to the type of work in a single area, it is necessary to store the type of work in each of the multiple identification media and to arrange each of the multiple identification media, which tends to make the preparation work complicated.

[0005] The objective of the present invention is to provide an agricultural work management support system that allows for efficient confirmation of the status of agricultural work in the field with a simple configuration. [Means for solving the problem]

[0006] The present invention relates to an agricultural work management support system that assists in managing the progress of agricultural work, comprising: an object placed in a field; a portable object carried by an agricultural worker performing the agricultural work; a storage device; a control device; and a display device. One of the object and the portable object is an identification medium to which unique information has been attached in advance, and the other of the object and the portable object is a communication terminal capable of reading the unique information attached to the identification medium. The control device is configured to acquire reading history information from the communication terminal indicating information regarding the reading of the unique information by the communication terminal and to store it in the storage device, to identify areas where the agricultural work has been completed based on the reading history information, and to display on the display device in a manner that distinguishes between areas where the agricultural work has been completed by the agricultural worker and areas where the agricultural work has not yet been completed by the agricultural worker.

[0007] According to the present invention, objects are placed in the field, reducing the workload of farmers in reading unique information. Furthermore, reading history information indicating that the communication terminal has read the unique information is stored in a storage device, and the completed areas are displayed on a display device based on the reading history information. This configuration allows, for example, managers or operators to distinguish at a glance which areas have been worked in. In addition, the configuration allows farmers to determine whether or not farm work is completed simply by having the communication terminal read the identification medium, without having to worry about the type of work performed. Compared to a configuration where multiple types of objects corresponding to multiple tasks are placed, the effort required of farmers to select the target object is reduced. As a result, a farm work management support system is realized that allows for efficient confirmation of the status of farm work in the field with a simple configuration. Here, "area" refers to any area in the field, which may be the entire field or a part of the field. For example, the "area" could be a farm greenhouse set up in a field, a row of crops, a section of a single crop row, or a group of multiple farm greenhouses (or crop rows, sections, etc.).

[0008] The agricultural work management support system of the present invention is also applicable to an agricultural work management support program that assists in managing the progress of agricultural work. The agricultural work management support program is an agricultural work management support program executed by the above-described agricultural work management support system, and causes a computer to execute the following functions: a storage function that acquires the reading history information indicating that the unique information has been read by the communication terminal and stores it in the storage device; an identification function that identifies the area where the agricultural work has been completed based on the reading history information; and a display function that displays on the display device in a way that distinguishes between the area where the agricultural work has been completed by the agricultural worker and the area where the agricultural work has not yet been completed by the agricultural worker.

[0009] The agricultural work management support program of the present invention realizes an agricultural work management support system that allows for efficient confirmation of the status of agricultural work in the field with a simple configuration.

[0010] In the present invention, it is preferable that the identification medium is configured to perform wireless communication using electric power generated inside by the action of an externally applied magnetic field, and the communication terminal has a magnetic field output unit that outputs the magnetic field.

[0011] With this configuration, wireless communication between the identification medium and the communication terminal is realized. As a result, the labor of the farmer for reading the unique information is further reduced.

[0012] In the present invention, it is preferable that the arrangement is fixed in the region via a restraint member that can be extended to approach the portable object.

[0013] With this configuration, the farmer can read the unique information with the communication terminal simply by approaching the arrangement to the portable object. Therefore, the farmer does not need to perform an operation such as taking out the portable object from the pocket deliberately, and the risk of soiling the portable object with mud or the like is also avoided. Further, since the arrangement is fixed in the region by the restraint member, loss of the arrangement is prevented.

[0014] In the present invention, it is preferable that the portable object is carried by the farmer via a restraint member that can be extended to approach the arrangement.

[0015] With this configuration, the portable object is worn by the farmer with the restraint member. Therefore, the risk that the farmer accidentally loses the portable object is avoided.

[0016] In the present invention, the region is divided for each section preset in the field, and the control device stores the arrangement position of each of the plurality of arrangements in the region in the storage device, and based on the reading history information and the arrangement position of the arrangement used for reading the unique information, identifies a worked section indicating the section in the region where the farmer has worked, and is configured to display the section on the display device so as to be distinguishable from the worked section and the sections other than the worked section.

[0017] According to this configuration, an object is placed at a distinguishable position in a preset section of the field area. Thereby, the work burden of the farmer regarding the reading of the unique information is reduced. Further, in a configuration where the completed work sections based on the reading history information and the placement position of the object are displayed on the display device, for example, an administrator, an operator, or the like can distinguish at a glance in which section the farming work has been performed.

[0018] In the present invention, it is preferable that at least one of the plurality of objects is arranged for each of the sections.

[0019] With this configuration, for example, an administrator, an operator, or the like can distinguish at a glance in which section the farming work has been performed.

[0020] In the present invention, it is preferable that each of the plurality of objects is arranged at a distinguishable position between one end portion of one of the sections and the other end portion of one of the sections in the area.

[0021] With this configuration, for example, an administrator, an operator, or the like can distinguish at a glance in which section the farming work has been completed and in which section the farming work is currently being performed.

[0022] In the present invention, the control device is preferably configured to receive registration of work schedule information including the section in which the farmer plans to work, calculate the progress degree of the work schedule information based on the completed work sections, and display the progress degree on the display device.

[0023] With this configuration, for example, an administrator, an operator, or the like can easily confirm whether the farming work in a predetermined section is being carried out as planned.

[0024] In the present invention, the type of the farming work is included in the work schedule information, and the control device is preferably configured to display the progress degree together with the type of the farming work on the display device.

[0025] This configuration allows administrators and operators, for example, to easily confirm whether the designated agricultural work is being carried out as scheduled by checking the type of work displayed on the display device.

[0026] In the present invention, it is preferable that the work schedule information includes information about the farm worker who is scheduled to perform the work, the reading history information includes information about the farm worker who carries the portable item, and the control device is configured to accept registration of a plurality of work schedule information and to determine which of the plurality of work schedule information the reading history information obtained from the communication terminal corresponds to, based on the information about the farm worker included in the reading history information and the information about the farm worker included in each of the plurality of work schedule information.

[0027] This configuration allows for the registration of multiple work schedules, and each of these schedules includes information about the farm worker responsible for the work. Therefore, managers and operators can easily check the progress of the work of each farm worker linked to each of the multiple work schedules.

[0028] In the present invention, it is preferable that the control device is configured to identify a plurality of sections assigned between a first position, which is the placement position of the object used when the communication terminal reads the unique information from the identification medium when the farm worker performs one of the farm tasks, and a second position, which is the placement position of the object used when the communication terminal reads the unique information from the identification medium in the area where the farm work is performed after the completion of the farm work at the first position, as the previously completed work section.

[0029] With this configuration, even if a farm worker forgets to read the unique information between the first and second positions, the area between the first and second positions is identified as a previously worked area. This ensures robustness against such forgotten readings, as the previously worked area is identified even if reading is missed.

[0030] In the present invention, the agricultural work management support system is preferably equipped with a notification device, and the control device is configured to notify the notification device that there is no further acquisition of the next reading history information if a preset time has elapsed since the acquisition of the previous reading history information and no further reading history information has been acquired.

[0031] With this configuration, for example, managers or operators can be notified via a notification device if farmers are not making progress with their work, and can then perform checks on the fields and the farmers. This helps to reduce delays in farm work in designated areas.

[0032] In the present invention, the arrangement is the identification medium, and the control device is preferably configured to store in the storage device the unique information of each of the plurality of arrangements and the arrangement position of each of the plurality of arrangements in association with each other.

[0033] In this configuration, the unique information of the identification medium is mapped to its placement location. This makes it possible to map the placement object to its placement location using the unique information. [Brief explanation of the drawing]

[Figure 9] This is a flowchart illustrating the process in modified example 2 and modified example 3.

[Figure 11] This is a plan view showing an example of field divisions and the arrangement of objects in modified example #3. [Modes for carrying out the invention]

[0035] [Example of field layout] As shown in Figure 1, a farm greenhouse 1 is provided as an example of a field. The farm greenhouse 1 is equipped with an entrance 10. The entrance 10 is, for example, a sliding door. Inside the farm greenhouse 1, cultivation rows A1 to A4 and B1 to B4 of cultivated plants Q are arranged. In cultivation row A1, two rows of cultivated plants Q, such as tomatoes, are planted. In each of cultivation rows A2 to A4 and B1 to B4, two rows of cultivated plants Q are planted, similar to cultivation row A1.

[0036] Cultivation row A1 is divided into six sections, A10 to A15. Cultivation plant Q is planted in a single row across sections A10 to A12, and cultivation plant Q is planted in a single row across sections A13 to A15. One NFC (Near Field Communication) tag 2 is placed in each of sections A10 to A15.

[0037] Cultivation row A2 is divided into six sections, A20 to A25. Cultivation plant Q is planted in a single row across sections A20 to A22, and cultivation plant Q is planted in a single row across sections A23 to A25. One NFC tag 2 is placed in each of sections A20 to A25.

[0038] Cultivation row A3 is divided into six sections, A30 to A35. Cultivation plant Q is planted in a single row across sections A30 to A32, and cultivation plant Q is planted in a single row across sections A33 to A35. One NFC tag 2 is placed in each of sections A30 to A35.

[0039] Cultivation row A4 is divided into six sections, A40 to A45. Cultivation plant Q is planted in a single row from section A40 to A42, and cultivation plant Q is planted in a single row from section A43 to A45. One NFC tag 2 is placed in each of the sections A40 to A45.

[0040] Cultivation row B1 is divided into six sections, B10 to B15. Cultivation plant Q is planted in a single row across sections B10 to B12, and cultivation plant Q is planted in a single row across sections B13 to B15. One NFC tag 2 is placed in each of sections B10 to B15.

[0041] Cultivation row B2 is divided into six sections, B20 to B25. Cultivation plant Q is planted in a single row across sections B20 to B22, and cultivation plant Q is planted in a single row across sections B23 to B25. One NFC tag 2 is placed in each of sections B20 to B25.

[0042] Cultivation row B3 is divided into six sections, B30 to B35. Cultivation plant Q is planted in a single row across sections B30 to B32, and cultivation plant Q is planted in a single row across sections B33 to B35. One NFC tag 2 is placed in each of sections B30 to B35.

[0043] Cultivation row B4 is divided into six sections, B40 to B45. Cultivation plant Q is planted in a single row from section B40 to B42, and cultivation plant Q is planted in a single row from section B43 to B45. One NFC tag 2 is placed in each of sections B40 to B45.

[0044] Each of the multiple NFC tags 2 described above corresponds to an "object" and an "identification medium." Each of the multiple NFC tags 2 stores unique information n (see Figure 2), and each of these unique pieces of information n is different. The unique information n does not overlap among the multiple NFC tags 2 and only needs to be information that can identify one NFC tag 2. Each unique piece of information n may be information unrelated to farming information or cultivation information (for example, a meaningless string of characters). This unique information n is read by the mobile communication terminal 5. Specifically, the NFC tag 2 is configured to perform wireless communication using power generated internally by the action of an externally applied magnetic field. The mobile communication terminal 5 has a magnetic field output unit 5A (see Figure 2) that outputs a magnetic field. The mobile communication terminal 5 corresponds to an "object" and a "communication terminal."

[0045] It is also acceptable for NFC tag 2 to be configured to store only unique information n, without storing information such as the type of work or the type of cultivated plant Q. In this configuration, the effort of storing information in NFC tag 2 is eliminated, and workers only need to place one NFC tag 2 in each of the sections A10-A45 and B10-B45. Alternatively, NFC tag 2 may be configured to store information such as the type of work and the type of cultivated plant Q in addition to unique information n.

[0046] Each of the multiple NFC tags 2 is fixed to the support 3 of the cultivated plant Q via an extendable string 4 (corresponding to a "restraining member"). In other words, the NFC tags 2 are fixed within the compartment via the extendable string 4 to bring them closer to the mobile communication terminal 5 (portable device). The NFC tags 2 may also be fixed via other extendable members (e.g., a reel cord).

[0047] Farm workers' hands are often dirty from their work. Therefore, if the configuration requires farmers to bring the mobile communication terminal 5 close to the NFC tag 2 by hand, there is a risk that the farmers may drop the mobile communication terminal 5 on the ground or that the mobile communication terminal 5 may become dirty. On the other hand, NFC tags 2 are often light and durable, and are unlikely to cause any particular problems even if dropped on the ground or their surface becomes dirty. Therefore, with this configuration, farmers can have the mobile communication terminal 5 read the unique information n by bringing the NFC tag 2 close to the mobile communication terminal 5 without touching the mobile communication terminal 5.

[0048] Additionally, an NFC tag 20 is provided near the entrance / exit 10. The configuration of the NFC tag 20 is the same as that of the NFC tag 2 described above.

[0049] [Configuration of the agricultural work management support system] As shown in Figure 2, the agricultural work management support system of this embodiment is equipped with the aforementioned NFC tags 2 and 20, a portable communication terminal 5 for agricultural workers, a control device 6, and a portable communication terminal 7 for the administrator. The portable communication terminal 5, the control device 6, and the portable communication terminal 7 are each configured to communicate using a mobile communication system (for example, wireless broadband communication based on the IEEE 802.16 standard).

[0050] The mobile communication terminal 5 includes the magnetic field output unit 5A, the reading unit 5B, and the browser 5C. The magnetic field output unit 5A and the reading unit 5B are each composed of a combination of hardware and software. The reading unit 5B is configured to receive unique information n transmitted wirelessly from the NFC tags 2 and 20 when power is generated inside the NFC tags 2 and 20 based on the magnetic field applied by the magnetic field output unit 5A.

[0051] Browser 5C is mainly composed of software and has the function of displaying unique information n, etc., read by the reading unit 5B on the display of the mobile communication terminal 5. In addition, the software of browser 5C has the function of transmitting unique information n, etc., to the outside via a communication module (not shown) inside the mobile communication terminal 5.

[0052] The control device 6 includes a work area identification unit 6A, a progress calculation unit 6B, a storage unit 6C, and a schedule information registration unit 6D.

[0053] The memory unit 6C is a storage medium (device) that includes volatile memory and non-volatile memory. The control device 6 stores in the memory unit 6C the unique information n of each of the multiple NFC tags 2, 20 and the placement location indicating whether each of the multiple NFC tags 2, 20 in the farm greenhouse 1 is located in section A10~A45, B10~B45, or entrance / exit 10, in association with each other.

[0054] The unique information n transmitted by the mobile communication terminal 5 is stored in the storage unit 6C as read history information linked to the information of the farm worker carrying the mobile communication terminal 5 (for example, user login information) and the date and time of transmission transmitted by the mobile communication terminal 5. In other words, the control device 6 obtains read history information from the mobile communication terminal 5 that indicates information regarding the reading of unique information n by the mobile communication terminal 5 and stores it in the storage unit 6C.

[0055] The completed work area identification unit 6A reads the reading history information from the storage unit 6C to identify the location where the farm worker is performing their work and to identify information regarding how far the farm worker has completed their work since starting it. In other words, the completed work area identification unit 6A of the control device 6 identifies a completed work area among sections A10-A45 and B10-B45 in the farm greenhouse 1, based on the reading history information and the placement locations of the NFC tags 2 and 20 stored in correspondence with unique information n. The completed work area identification unit 6A also identifies whether the NFC tags 2 and 20 indicated by the reading history information are located at the entrance 10 or in which section by referring to the placement locations stored in the storage unit 6C.

[0056] In this embodiment, the control device 6 is configured to store work schedule data (work schedule information) indicating information about the schedule of agricultural work in the storage unit 6C. As shown in Figure 3, the work schedule data includes the scheduled work No., work location, person in charge, work date and time, and type of work. The work location indicates which of cultivation rows A1-A4 or B1-B4 in the agricultural greenhouse 1 it is. The person in charge is information about the agricultural worker who is scheduled to work at the work location (e.g., name, employee number, ID, etc.). The work date and time is the date and time when the agricultural worker will perform the agricultural work at the work location. The type of work indicates the type of agricultural work, and examples include bud removal, leaf removal, pinching, pollination, harvesting, etc.

[0057] The schedule information registration unit 6D shown in Figure 2 accepts registration of work schedule data, including plots A10-A45 and B10-B45 where agricultural workers are scheduled to work, from, for example, the administrator's mobile communication terminal 7. The schedule information registration unit 6D can accept registration of multiple work schedule data, as shown in Figure 3. That is, the control device 6 accepts registration of multiple work schedule data. The multiple work schedule data are stored as array data as shown in Figure 3. Note that the array data shown in Figure 3 may be, for example, a chain structure (list structure).

[0058] The progress calculation unit 6B calculates the degree of progress of agricultural work relative to the work schedule data, based on the completed work plots. However, if there is no work schedule data that matches the read history information, the progress calculation unit 6B does not calculate the degree of progress relative to the work schedule data.

[0059] The administrator's mobile communication terminal 7 is equipped with a browser 7A. Browser 7A is mainly composed of software. Browser 7A has the function of displaying on the mobile communication terminal 7's display the current work location of the farm worker, the completed work area identified by the completed work area identification unit 6A (areas in the farm greenhouse 1 where farm work has been completed), the progress level calculated by the progress calculation unit 6B, etc.

[0060] In other words, the control device 6 is configured to display on the mobile communication terminal 7 that sections A10-A45 and B10-B45 can be distinguished as completed work sections and sections that have not been completed work sections.

[0061] Furthermore, the control device 6 is configured to display the progress on the mobile communication terminal 7 if there is work schedule data that matches the reading history information. In this case, the control device 6 is configured to display the progress along with the type of agricultural work on the mobile communication terminal 7.

[0062] Figure 4 shows a flowchart illustrating the processing steps of the agricultural work management support system. This flowchart is executed in a cyclical process at regular intervals. In other words, the process spanning from the start to the end of the flowchart shown in Figure 4 is executed repeatedly and periodically.

[0063] The control device 6 receives unique information n from the mobile communication terminal 5 of a certain worker A. m Step #01 determines whether or not reading history information indicating the above has been acquired. m is the number of unique pieces of information n acquired by the control device 6 from the start of a predetermined farming task by worker A. In the example shown in Figure 4, it is defined that worker A reads the NFC tag 2 at the time when they start farming in that section. This definition requires a configuration to determine when worker A has completed farming in the last section. For this reason, after worker A has finished farming in the last section of the planned sections, worker A reads the NFC tag 20 at the entrance / exit 10 just before leaving the farmhouse 1. This allows the control device 6 to determine that worker A has completed farming in all of the planned sections.

[0064] If the control device 6 does not acquire read history information from worker A's mobile communication terminal 5 (Step #01: No), the control device 6 determines whether it has already acquired read history information indicating unique information n1 (Step #16). If it has not already acquired read history information indicating unique information n1 (Step #16: No), the control device 6 determines that worker A has not started the predetermined farm work, terminates the processing at that point, and waits for the next cycle processing.

[0065] If read history information indicating unique information n1 has already been acquired (Step #16: Yes), the control device 6 determines whether a preset time has elapsed since the previous acquisition of read history information (Step #17). If the preset time has not elapsed since the previous acquisition of read history information (Step #17: No), the control device 6 terminates the processing at that point and waits for the next cycle processing. If the preset time has elapsed since the previous acquisition of read history information (Step #17: Yes), the control device 6 then acquires the next unique information n m The browser 7A of the mobile communication terminal 7 is notified that no reading history information related to it has been obtained (step #18), and the processing at that point is terminated, and the system waits for the next cycle processing.

[0066] In other words, the control device 6 is configured to notify the mobile communication terminal 7 (notification device) that no further reading history information has been obtained if a preset time has elapsed since the previous reading history information was acquired and no further reading history information has been obtained. This allows the manager to call, email, or send a text message to the farm worker's mobile communication terminal 5 from the mobile communication terminal 7 to check on worker A's status. If no further reading history information is obtained, that is, if worker A has not read the NFC tag 2, there is a possibility that some kind of trouble has occurred (such as illness or work interruption due to a problem). The notification allows the manager to deal with the trouble.

[0067] The control device 6 receives the unique information n mWhen read history information indicating that has been read is obtained (Step #01: Yes), the control device 6 stores the read history information in the storage unit 6C (Step #02). The process in Step #02 corresponds to a storage function that obtains read history information indicating that the unique information n has been read by the mobile communication terminal 5 (communication terminal) and stores it in the storage unit 6C.

[0068] The control device 6 determines whether the number of m is 2 or more (step #03). In other words, in step #03, the control device 6 determines whether it has obtained two or more unique pieces of information n from worker A's mobile communication terminal 5.

[0069] If the number of m is less than 2 (Step #03: No), the control device 6 has acquired only one unique piece of information n (only n1) from worker A's mobile communication terminal 5. Therefore, the completed work area identification unit 6A determines that worker A has not yet completed any work areas (Step #05). The completed work area identification unit 6A then determines the location where the one unique piece of information n1 was acquired as worker A's current work location (Step #15-1), and then terminates the processing at that point and waits for the next cycle processing. In other words, if the control device 6 acquires only one unique piece of information n (only n1) from worker A's mobile communication terminal 5, the completed work area identification unit 6A determines the placement location of the NFC tag 2 corresponding to the one unique piece of information n1 as worker A's current work location.

[0070] If the number of m is 2 or more (Step #03: Yes), the previously worked area identification unit 6A identifies the unique information n from the area corresponding to the unique information n1 (the area where the NFC tag 2 corresponding to the unique information n1 exists). m-1 The corresponding section (unique information n) m-1 It is determined that worker A's work is complete up to the section where the corresponding NFC tag 2 exists (step #04-1). As shown in Figure 5, worker A has the mobile communication terminal 5 read the unique information n1 of NFC tag 2 in section A10, and then the unique information n of NFC tag 2 in section A15 mWhen the data is read by the mobile communication terminal 5, sections A10 to A14 become completed work areas, as indicated by the check marks in Figure 6. It is then identified that worker A is performing agricultural work in section A15. These completed work areas and worker A, who is performing agricultural work in section A15, are displayed in the browser 7A of the mobile communication terminal 7.

[0071] Furthermore, between section A10 and section A15, NFC tags 2 are present in four locations: sections A11, A12, A13, and A14. It is possible that worker A may forget to read at least one of the NFC tags 2 in sections A11, A12, A13, and A14. Even in such a case, when the unique information n is read from the respective NFC tags 2 in section A10 (first location) and section A15 (second location), the control device 6 identifies sections A11 to A14, which are assigned between section A10 (first location) and section A15 (second location), as already worked sections. Of the identified sections A11 to A14, sections corresponding to NFC tags 2 that worker A has not read may be displayed in a different color or with a message in the browser 7A of the mobile communication terminal 7. This configuration makes it easier for administrators to confirm the actual work status of worker A in the relevant section.

[0072] In other words, the control device 6 is configured to identify as previously worked areas multiple sections (e.g., sections A11 to A14) that are located between a first location (e.g., section A10), which is the location of the NFC tag 2 (placement object) used when the mobile communication terminal 5 read the unique information n while a farm worker was performing a single farm task, and a second location (e.g., section A15), which is the location of the NFC tag 2 (placement object) used when the mobile communication terminal 5 read the unique information n among multiple sections A10 to A15 where farm work is performed after the completion of farm work at the first location. This configuration ensures robustness against worker A forgetting to read the NFC tag 2.

[0073] Incidentally, the process of step #04 corresponds to a specific function of identifying a completed work section of the farmer in the agricultural house 1 (area) based on the reading history information and the placement position of the object used for reading the unique information n. At that time, the function of displaying the state shown in FIG. 6 on the browser 7A of the mobile communication terminal 7 corresponds to a display function of displaying on the mobile communication terminal 7 (display device) so that the section can be distinguished between a completed work section and a section other than the completed work section.

[0074] The processes shown in steps #06 to #13 are processes for calculating the progress by the progress calculation unit 6B. Among them, the processes shown in steps #06 to #09 are processes for searching the storage unit 6C for work schedule data that matches the content of the agricultural work being performed by the worker A.

[0075] To read the data at the head of the array (or list structure) shown in FIG. 3, the control device 6 first sets the variable X for the array to 1 (step #06) and determines whether there is work schedule data for the array of work No. X (initially No. 1) (step #07). If the work schedule data is not registered, the determination in step #07 is No, and the progress calculation is not performed. In this case, the completed work section identification unit 6A determines the placement position of the NFC tag 2 corresponding to the last acquired unique information n as the current work position of the worker A (step #15-1), and then ends the processing at that time and waits for the next cycle processing. m and waits for the next cycle processing.

[0076] When there is work schedule data for work No. X in the storage unit 6C (step #07: Yes), the control device 6 reads the work schedule data for work No. X (step #08) and determines whether the reading history information indicating the unique information n1 to n from the worker A and the work schedule data for work No. X match (step #09). As described above, the unique information n transmitted by the mobile communication terminal 5 is stored in the storage unit 6C as reading history information associated with the information of the farmer carrying the mobile communication terminal 5 and the transmission date and time transmitted by the mobile communication terminal 5. In step #09, specifically, the control device 6 m determines whether the reading history information indicating the unique information n1 to n from the worker A and the work schedule data for work No. X match (step #09). As described above, the unique information n transmitted by the mobile communication terminal 5 is stored in the storage unit 6C as reading history information associated with the information of the farmer carrying the mobile communication terminal 5 and the transmission date and time transmitted by the mobile communication terminal 5. In step #09, specifically, the control device 6 mThe system determines whether the information and transmission date / time associated with worker A match the assigned person and work date / time included in the work schedule data.

[0077] In other words, in step #09, the control device 6 is configured to determine which of the multiple work schedule data the read history information acquired from the mobile communication terminal 5 corresponds to, based on the information about worker A included in the read history information and the information about the person in charge included in each of the multiple work schedule data.

[0078] Unique information from worker A n1~n m If the read history information indicating and the work schedule data for work No. X do not match (step #09: No), the value of X is incremented (step #10), and it is determined whether or not the next work schedule data exists in the array (step #07). In step #09, unique information n1~n m Steps #07 to #09 are repeated until the reading history information and the work schedule data for work No. X match.

[0079] Note that in step #09, unique information n1~n m If no work schedule data exists that matches the specified work schedule data, the value of X is incremented by the number of existing work schedule data (step #10), and then in step #07, the determination is No because the "number of existing + 1" work schedule data does not exist. Cases in which this may occur include, for example, when the manager has not created the corresponding work schedule data (including forgetting to create it), or when worker A is mistakenly working in another section or performing a different type of work. In this case, the control device 6 notifies, for example, a mobile communication terminal 7, that no work schedule data corresponding to worker A's farm work exists (step #11). Then, the previously acquired work section identification unit 6A uses the last acquired unique information n m The placement location of the corresponding NFC tag 2 is determined to be the current work location of worker A (step #15-1), and the processing at that point is terminated, and the system waits for the next cycle processing.

[0080] Unique information from worker A n1~n m When the work schedule data for work No. X matches (Step #09: Yes), the progress calculation unit 6B of the control device 6 calculates the progress of worker A's farm work against the work schedule based on the work schedule data (Step #12). At this time, the control device 6 displays the progress on the browser 7A of the administrator's mobile communication terminal 7. Furthermore, when worker A reads the NFC tag 20 at the entrance 10 just before leaving the farm greenhouse 1, the unique information n obtained from the NFC tag 20 is read. m Based on this, the unique information n is obtained from the section corresponding to unique information n1 (the section where NFC tag 2 corresponding to unique information n1 exists). m-1 The corresponding section (unique information n) m-1 The system determines that agricultural work has been completed up to the section where the corresponding NFC tag 2 exists, and calculates the progress of the agricultural work relative to the planned work data.

[0081] The control device 6 then determines whether the progress has reached 100 percent (step #13). If the progress is not 100 percent (step #13: No), the previously worked area identification unit 6A retrieves the last acquired unique information n m The placement location of the corresponding NFC tag 2 is determined to be the current work location of worker A (step #15-1), and the processing at that point is terminated, and the system waits for the next cycle processing.

[0082] On the other hand, if the progress is 100 percent (Step #13: Yes), the work area identification unit 6A determines that worker A's work is finished and sets worker A's current work location to none (Step #14). Then it terminates the processing at that point and waits for the next cycle processing.

[0083] The progress is calculated and displayed on the browser 7A of the administrator's mobile communication terminal 7, allowing the administrator to check the current location of worker A and whether worker A's farm work is on schedule or behind schedule. The progress calculation unit 6B of the control device 6 may also calculate the estimated completion time of worker A's farm work in addition to the progress of worker A's farm work and display the estimated completion time on the browser 7A of the administrator's mobile communication terminal 7.

[0084] [Variation 1] In the embodiment described above, based on the flowchart illustrated in Figure 4, it is defined that worker A reads the NFC tag 2 when starting agricultural work in that section. The embodiment is not limited to this one, and it may also be defined as reading the NFC tag 2 when worker A has completed agricultural work in that section. In this definition, a configuration is required to determine when worker A has started agricultural work. For this reason, before worker A starts agricultural work in the first section of the planned sections, worker A reads the NFC tag 20 at the entrance 10 when entering the farm house 1. This allows the control device 6 to determine that worker A has started agricultural work.

[0085] Figure 7 shows a flowchart where worker A reads NFC tag 2 when they complete farm work in that section. Note that in Figure 7, the steps with the same step numbers as in Figure 4 are the same processes as in Figure 4. The process of step #04-1 shown in Figure 4 is changed to the process of step #04-2 ​​in Figure 7, and the process of step #15-1 shown in Figure 4 is changed to the process of step #15-2 in Figure 7.

[0086] If the number of m is 1 (Step #03: No), it means that worker A has only read the NFC tag 20 at the entrance / exit 10 so far. At this point, the completed work area identification unit 6A determines that worker A has not yet completed any work areas (Step #05) and proceeds to the process in Step #06.

[0087] If the number of m is 2 or more (Step #03: Yes), the previously worked area identification unit 6A identifies the unique information n from the area corresponding to the unique information n2 (the area where the NFC tag 2 corresponding to the unique information n2 exists). m The corresponding section (unique information n) m It is determined that worker A's work is complete up to the point where the corresponding NFC tag 2 exists (step #04-2).

[0088] In Figure 7, steps #06 to #13 represent the progress calculation process performed by the progress calculation unit 6B. Of these, steps #06 to #09 represent the process of searching the storage unit 6C for work schedule data that matches the content of the farm work being performed by worker A.

[0089] In this case, if there is no work schedule data corresponding to worker A's farm work (step #07: No), the control device 6 notifies that there is no work schedule data corresponding to worker A's farm work, as described above based on Figure 4 (step #11). In this case, since the plot where worker A will perform farm work next is not known, the flowchart process shown in Figure 7 terminates after the execution of step #11 and waits for the next cycle process.

[0090] If work schedule data corresponding to worker A's farm work exists (Step #07: Yes), and the progress is not 100 percent (Step #13: No), the previously identified work area unit 6A will then acquire the next unique information n m+1 The corresponding location is identified based on the work schedule data, and that location is determined to be the current work location of worker A (step #15-2). Then the processing at that point is terminated and the system waits for the next cycle processing.

[0091] When worker A first enters the farm greenhouse 1, they have their mobile communication terminal 5 read the unique information n1 of the NFC tag 20 at the entrance 10. Then, applying this to the example shown in Figure 5, worker A has their mobile communication terminal 5 read the unique information n2 of the NFC tag 2 in section A10, and then in section A14, the unique information n mWhen this is read by the mobile communication terminal 5, sections A10 to A14 become previously worked sections, as indicated by the check marks in Figure 6. Then, worker A receives unique information n m+1 Based on the work schedule data, it is identified that agricultural work is being performed in the corresponding section A15. This already worked section and worker A, who is performing agricultural work in section A15, are displayed in the browser 7A of the mobile communication terminal 7.

[0092] [Variation 2] In the example shown in Figure 8, NFC tags 2 are placed at both ends in the longitudinal direction of each section. That is, more than one NFC tag 2 may be placed in a single section. In this configuration, worker A reads the NFC tags 2 at the start and end times of agricultural work in each section. That is, each of the multiple NFC tags 2 is placed in a location within the area (farm greenhouse 1) that allows for the distinction between one end of a section and the other end of a section. This makes it possible for worker A to understand information about which section's agricultural work has been completed and which section they are currently working in. In the example shown in Figure 8, an NFC tag 20 may or may not be provided near the entrance / exit 10.

[0093] Figure 9 shows a flowchart corresponding to the example shown in Figure 8. Note that in Figure 9, the steps with the same step numbers as in Figure 4 represent the same processing as shown in Figure 4. The processing of step #04-1 shown in Figure 4 has been changed to the processing of step #04-3 in Figure 9. In step #04-3, the previously worked area identification unit 6A processes unique information n1 to unique information n m The section that exists between (unique information n1 and unique information n m For the sections between the two NFC tags 2 corresponding to each of the two, if reading is completed at both the start and end points of the section, it is determined that the worker A's work is complete (step #04-3). The processing for the other step numbers shown in Figure 9 is as described above based on Figure 4.

[0094] In Figure 8, two NFC tags 2 are placed adjacent to each other, straddling the boundary between section A14 and section A15. As shown in Figure 5, worker A has the mobile communication terminal 5 read the unique information n1 of the NFC tag 2 at the end of the work start position in section A10, and then the unique information n of the NFC tag 2 on the section A14 side of the two NFC tags 2 is read. m When the mobile communication terminal 5 reads the data, sections A10 to A14 become completed work areas, as indicated by the check marks in Figure 6. Also, when worker A reads the data from the NFC tag 2 on section A15, rather than the NFC tag 2 on section A14, unique information n m Even if the data is read by the mobile communication terminal 5, the configuration may be such that sections A10 to A14 are already working sections, as indicated by the check marks in Figure 6.

[0095] Then, at the moment worker A starts farming in section A15, the unique information n is obtained from the NFC tag 2 on the section A15 side of the two NFC tags 2. m When this is read by the mobile communication terminal 5, it is identified that worker A is performing agricultural work in section A15. This already worked section and worker A, who is performing agricultural work in section A15, are displayed in the browser 7A of the mobile communication terminal 7.

[0096] [Variation 3] In the embodiment illustrated in Figure 1, one NFC tag 2 is placed in each of sections A10-A45 and B10-B45. The embodiment is not limited to this one, and as shown in Figure 10, the NFC tags 2 may not belong to sections A10-A45 or B10-B45.

[0097] In the example shown in Figure 10, NFC tags 2 are placed at the edges of sections A10 and A12. NFC tags 2 are also placed at the boundary between section A10 and section A11, and between section A11 and section A12. Similarly, NFC tags 2 are placed at the edges of sections A13 and A15. Furthermore, NFC tags 2 are placed at the boundary between section A13 and section A14, and between section A14 and section A15.

[0098] In other words, in sections A10 to A15, NFC tags 2 are placed at the boundaries where sections are adjacent along the longitudinal direction, and at the ends where sections are not adjacent along the longitudinal direction. The same applies to sections A20 to A25, A30 to A35, A40 to A45, B10 to B15, B20 to B25, B30 to B35, and B40 to B45.

[0099] Furthermore, as shown in Figure 11, the NFC tags 2 may be placed at the boundary points where adjacent sections meet along the longitudinal direction, and at the boundary points where adjacent sections meet along the short direction, among the end points where sections do not meet along the longitudinal direction.

[0100] In the example shown in Figure 11, NFC tags 2 are placed at the boundaries between adjacent sections along the longitudinal direction in sections A10 to A15. Additionally, NFC tags 2 are placed at the boundaries between the left edge of section A10 and the left edge of section A15, and at the boundaries between the right edge of section A12 and the right edge of section A13. The same applies to sections A20 to A25, A30 to A35, A40 to A45, B10 to B15, B20 to B25, B30 to B35, and B40 to B45.

[0101] In other words, in the examples shown in Figures 10 and 11, each of the multiple NFC tags 2 is placed in a location within the area (farmhouse 1) where it is possible to distinguish between one end of one section and the other end of one section. Even when the NFC tags 2 are arranged as in the examples shown in Figures 10 and 11, when worker A reads the NFC tags 2, the process based on the flowchart shown in Figure 9 is executed, similar to the "Modification Example 2" described above. Applying this to the example shown in Figure 5, worker A has the mobile communication terminal 5 read the unique information n1 of the NFC tag 2 at the end of section A10, and then the unique information n of the NFC tag 2 at the boundary between section A14 and section A15. mWhen the data is read by the mobile communication terminal 5, sections A10 to A14 become completed work areas, as indicated by the check marks in Figure 6. It is then identified that worker A is performing agricultural work in section A15. These completed work areas and worker A, who is performing agricultural work in section A15, are displayed in the browser 7A of the mobile communication terminal 7.

[0102] In the examples shown in Figures 10 and 11, the NFC tag 20 may or may not be provided near the entrance / exit 10.

[0103] [Another embodiment] The present invention is not limited to the configurations exemplified in the above embodiments, including Modification 1 to Modification 3, and a representative alternative embodiment of the present invention will be exemplified below.

[0104] (1) The present invention may be an agricultural work management support program executed in an agricultural work management support system. The agricultural work management support program has a storage function that acquires reading history information indicating that unique information n has been read by a mobile communication terminal 5 (communication terminal) and stores it in a storage unit 6C; a specification function that identifies agricultural greenhouses 1 (areas) where the agricultural work has been completed based on the reading history information; and a display function that displays on a mobile communication terminal 7 (display device) that it is possible to distinguish between agricultural greenhouses 1 (areas) where the agricultural work by agricultural workers has been completed and agricultural greenhouses 1 (areas) where the agricultural work by agricultural workers has not yet been completed. The agricultural work management support program may consist of, for example, an executable program generated by a compiler and a linker, or it may consist of code that is executed sequentially by an interpreter. Furthermore, a suitable agricultural work management support program may be configured to have the computer execute the following functions: a first storage function that stores the placement locations of placed objects in the storage unit 6C; a second storage function that acquires and stores in the storage unit 6C reading history information indicating that unique information n has been read by the mobile communication terminal 5 (communication terminal); an identification function that identifies completed work areas in the agricultural greenhouse 1 (area) based on the reading history information and the placement locations of the NFC tags 2 (placed objects) used to read the unique information n; and a display function that displays the areas on the mobile communication terminal 7 (display device) in a way that allows for the distinction between completed work areas and areas that have not been completed.

[0105] (2) In the above embodiment, the farm worker carries a portable communication terminal 5 (communication terminal, portable item), and NFC tags 2 (identification medium, placed item) are placed in each section. The farm worker then reads unique information n from the NFC tag 2 using the portable communication terminal 5. The embodiment is not limited to this one, and the configuration may be such that a communication terminal (placed item) is placed in each section, and the farm worker carries an NFC tag 2 (identification medium, portable item). Furthermore, each communication terminal placed in each section may be configured to read the unique information n attached to the NFC tag 2 (identification medium). That is, one of the placed item and the portable item is an identification medium to which unique information n has been attached in advance, and the other of the placed item and the portable item is a communication terminal capable of reading the unique information n attached to the identification medium. When a communication terminal (placed item) is placed in each section, the control device 6 stores in the storage unit 6C the placement positions indicating the sections in which each of the multiple communication terminals (placed items) in the farm greenhouse 1 (area) is placed. Specifically, the storage unit 6C may store mapping information indicating the correspondence between the identification information (e.g., MAC address, serial number, etc.) of multiple communication terminals (placed objects) and sections A10-A45 and B10-B45. Alternatively, the storage unit 6C may store a link between the unique information n attached to the NFC tag 2 and the farm worker carrying the NFC tag 2.

[0106] (3) In the above embodiment, the NFC tags 2 are fixed within each compartment via a string 4. The embodiment is not limited to this, and the string 4 may be a restraining member such as a coil spring, a reel cord, or a wire. Alternatively, the NFC tags 2 may be fixed within each compartment without a string 4. In this case, the portable communication terminal 5 may be carried by the farm worker via a restraining member (string 4, coil spring, reel cord, wire, etc.). That is, one of the identification medium and the communication terminal may be fixed to the compartment via a restraining member that can be extended to bring it closer to the other of the identification medium and the communication terminal, or it may be carried by the farm worker. Alternatively, one of the identification medium and the communication terminal may be fixed to the compartment via a restraining member, and the other of the identification medium and the communication terminal may be carried by the farm worker via a restraining member.

[0107] (4) The administrator's mobile communication terminal 7 (display device) may be, for example, a stationary PC in a remote location, or a laptop computer or tablet computer. Alternatively, if the farm worker is also the administrator, the mobile communication terminal 5 (portable device, communication terminal) and the mobile communication terminal 7 (display device) may be the same terminal. In this case, the browser 5C and the browser 7A may be configured as a single unit.

[0108] (5) The NFC tag 2 may be, for example, a tag with a barcode or a two-dimensional code attached, or it may be an RFID (radio frequency identification) tag. If the identification medium is a tag with a barcode or a two-dimensional code attached, the configuration may be such that the barcode or two-dimensional code is read by the camera of the mobile communication terminal 5 (communication terminal).

[0109] (6) The configuration may include gamification elements, such as the display on the browser 5C of the mobile communication terminal 5 becoming more elaborate or discount points for shopping being awarded each time the farm worker successfully reads the NFC tag 2 in succession. This makes it easier for the farm worker to actively perform the NFC tag 2 reading task without forgetting.

[0110] (7) In the above-described embodiment, the control device 6 includes a storage unit 6C. The configuration is not limited to this, and the storage unit 6C may be a storage device independent of the control device 6, or a storage device integrated with the control device 6. Furthermore, the control device 6 and the storage unit 6C may be configured to be incorporated into an administrator's mobile communication terminal 7 or a stationary device (such as a desktop computer or server). Moreover, at least a part of the control device 6 and the storage unit 6C may be included in a cloud system built on the internet.

[0111] (8) In the process of step #11 shown in Figure 4, the control device 6 notifies, for example, the mobile communication terminal 7, that there is no work schedule data corresponding to worker A's farm work, but the control device 6 may be configured not to make this notification.

[0112] (9) In the above embodiment, sections A10-A45 and B10-B45 are set up in cultivation rows A1-A4 and B1-B4 of the cultivated plant Q inside the greenhouse 1. The embodiment is not limited to this, and there may be a configuration in which sections are not set up in cultivation rows A1-A4 and B1-B4 of the cultivated plant Q inside the greenhouse 1. In this case, an NFC tag 20 may be provided on a field basis (for each greenhouse 1). For example, there may be a configuration in which only one NFC tag 20 is provided near the entrance 10, or there may be a configuration in which NFC tags 20 are provided in two places, inside and outside the greenhouse 1, with the entrance 10 in between. In this case, for example, when a farm worker enters the greenhouse 1, the unique information n of the outer NFC tag 20 may be read by the mobile communication terminal 5, and when the farm worker exits the greenhouse 1, the unique information n of the inner NFC tag 20 may be read by the mobile communication terminal 5. In this configuration, the control device 6 identifies areas (farm greenhouses 1) where farm work has been completed based on the reading history information, and displays on the mobile communication terminal 7 in a way that distinguishes between areas (farm greenhouses 1) where farm work by farmers has been completed and areas (farm greenhouses 1) where farm work by farmers has not yet been completed.

[0113] Furthermore, the configurations disclosed in the above-described embodiments (including other embodiments, the same applies hereinafter) can be applied in combination with configurations disclosed in other embodiments, as long as no inconsistencies arise. In addition, the embodiments disclosed herein are illustrative, and the embodiments of the present invention are not limited thereto, and can be modified as appropriate without departing from the object of the present invention.
