Description

[Technical field]

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

[0002] In recent years, as the information-based agriculture has become more widespread, technologies have been developed to manage information based on the position information of working devices that can work in fields. For example, Patent Document 1 discloses a technology that generates information about the working range of a working device based on the results of measuring the position of the working device. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2023-1456 A Summary of the Invention [Problem to be solved by the invention]

[0004] In general, when a working device moves, there may be periods when information indicating its positioning position can be obtained and periods when it cannot. For example, a working device that performs work in a field may not move by itself when moving to a remote location, but may be transported by another vehicle. In many cases, the positioning function of the working device is turned off while being transported, so there may be no information indicating the positioning result during this period. When there is such a period in which there is no positioning result in parts or there are few positioning results, if a movement trajectory is generated or updated based on the positioning result, some of the managed information may indicate a movement trajectory that deviates from the route that the working device actually moved. If information about a movement trajectory with such a deviation is managed without distinguishing it from other trajectories, there is a risk of inconvenience in using it as agricultural information, such as a user becoming suspicious when seeing a movement trajectory displayed on a map.

[0005] In view of the above circumstances, one object of the present disclosure is to facilitate displaying a movement trajectory in a manner that is less likely to cause suspicion to a user. Other objects can be understood from the following description and the description of the embodiment. [Means for solving the problem]

[0014] (Embodiment 1) The farming information management system according to the embodiment will be described below with reference to the drawings. As shown in FIG. 1, the farming information management system 1 includes a farming information management device 10, one or more terminal devices 20, one or more work devices 30 that perform work in a field F1, etc., and one or more transport vehicles 40. When multiple fields (field F1, field F2, ..., etc.) are not distinguished from one another, they may simply be called fields F. The farming information management device 10, the one or more terminal devices 20, and the work devices 30 can communicate with each other via a network NT. The network NT is, for example, the Internet. In addition, the work devices 30 and the transport vehicles 40 can receive positioning signals transmitted by a positioning satellite GP.

[0015] The working device 30 may be, for example, an agricultural machine capable of working in the field F, such as a tractor, a combine, or a harvester. The working device 30 may be an agricultural drone that works in the field F. One or more working devices 30 may each perform agricultural work in two or more fields (for example, field F1, field F2, ..., etc.). The working device 30 may measure its own position and time based on a positioning signal from a positioning satellite GP while it is activated (while the key is on). The working device 30 may not measure its own position while it is not activated (while the key is off). Hereinafter, a period during which the working device 30 positions its own position is referred to as a positioning period, and a period during which the working device 30 does not position is referred to as a non-positioning period. In addition, the position of the working device 30 that has been positioned may be referred to as a positioning position, and the time at which the working device 30 positions itself may be referred to as a positioning time.

[0016] The transport vehicle 40 may be a vehicle capable of transporting the working implement 30, such as a truck, a trailer, or a freight train. The transport vehicle 40 may measure its own position and the positioning time based on a signal from a positioning satellite GP. For example, the transport vehicle 40 may transport the working implement 30 from the field F1 to the field F2.

[0017] The farming information management system 1 provides a user with information on the trajectory of the operation device 30 based on positioning information indicating the result of the operation device 30 measuring its own position. For example, the farming information management system 1 displays the trajectory of the operation device 30 on a screen S of the terminal device 20.

[0018] The working device 30 may move even during non-positioning periods, for example, when being transported by the transport vehicle 40 to move from a remote field F1 to a field F2. In particular, the working device 30 may have a structure specialized for work in the field F, and may move more frequently during non-positioning periods than an ordinary passenger vehicle, etc.

[0019] Here, as shown in Fig. 2, a case will be described as an example in which the working device 30 self-propels while working in the fields F1 and F2, and the working device 30 is transported from the field F1 to the field F2 by a transport vehicle 40. At this time, the period during which the working device is working in the fields F1 and F2 is a positioning period, and the period during transport is a non-positioning period. During the positioning period, the farming information management system 1 can acquire positioning information indicating the positioning results measured at a predetermined cycle (e.g., every 5 seconds), as shown by the black dots at positioning positions Pt_1, Pt_2, Pt_3, ... in Fig. 2. In the example of Figure 2, the positioning information that can be acquired includes positioning information indicating positioning positions Pt_1 to Pt_m corresponding to the positioning period during work in field F1, and positioning information indicating positioning positions Pt_m+1 to Pt_n corresponding to the positioning period during work in field F2.

[0020] The farming information management system 1 determines, as a movement trajectory L_k, a line connecting a positioning position Pt_k and a positioning position Pt_k+1 having consecutive positioning times among the positioning positions indicated by the acquired positioning information (where k=1, 2, 3, ..., n). A line connecting one or more movement trajectories L_1, L_2, ... may be called a route. In the example of FIG. 2, a route R1 corresponding to a positioning period during which work was performed in the field F1 includes movement trajectories L_1 to L_m-1. Moreover, a route R2 corresponding to a positioning period during which work was performed in the field F2 includes movement trajectories L_m+1 to L_n-1. It is considered that the routes R1 and R2 have a relatively small error from the route actually traveled by the working device 30.

[0021] However, since the period between the positioned position Pt_m during the positioning period in the field F1 and the positioned position Pt_m+1 that is positioned first during the positioning period in the field F2 corresponds to a non-positioning period, there may be a time or distance deviation between the two that exceeds a standard set by the settings. Therefore, the movement trajectory L_m connecting the positioned position Pt_m and the positioned position Pt_m+1 is highly likely to differ from the route PT that is the route along which the working device 30 was actually transported by the transport vehicle 40. Hereinafter, a movement trajectory (for example, the movement trajectory L_m) in which there is a time or distance deviation that exceeds a standard between the start point and the end point (the positioned position Pt_m and the positioned position Pt_m+1 in the example of FIG. 2) may be referred to as a deviation trajectory corresponding to a non-positioning period.

[0022] When generating or updating information on the trajectory of the working device 30 based on information indicating the positioning result of the working device 30, there are cases where the deviation between the route actually traveled by the working device 30 and the movement trajectory of the working device 30 indicated by the information managed by the farming information management system 1 becomes large during non-positioning periods. If information on such a deviated trajectory is managed without distinguishing it from other trajectories, there is a risk of inconvenience in using it as farming information, for example, when the trajectory is displayed on a map, such that the user becomes suspicious.

[0023] The farming information management system 1 of this embodiment estimates non-positioning periods based on at least one of the positioning location and the positioning time indicated by the positioning information of the working device 30. The farming information management system 1 then displays the trajectory corresponding to the non-positioning period (also called the non-positioning trajectory) in a manner different from other trajectories (also called the normal trajectory). Therefore, the farming information management system 1 can display the movement trajectory in a manner that is less likely to arouse suspicion in the user.

As shown in Fig. 3, the farming information management device 10 included in the farming information management system 1 comprises an input / output device 12, a calculation device 14, a communication device 16, and a storage device 18.

[0047] Next, functions of the farming information management system 1 will be described with reference to Fig. 7. The operation device 30 realizes the functions of the sampling unit 310 and the output unit 320 in Fig. 7 by the calculation device 34 in Fig. 5 executing the program P3.

[0048] As described below, the sampling unit 310 of the working device 30 continuously measures the position and time of the working device 30 using the positioning device 39 at a predetermined timing (for example, every 5 seconds) while the power source 31 of the working device 30 is in an activated state. The sampling unit 310 generates positioning information indicating the measured position and time (i.e., the measured position and measured time of the working device 30).

[0049] The output section 320 of the operation device 30 transmits the positioning information generated by the sampling section 310 to the farming information management device 10 using the communication device 36.

[0050] The transfer vehicle 40 realizes the functions of a sampling unit 410 and an output unit 420 in FIG. 7 by the calculation device 44 in FIG. 6 executing the program P4.

[0051] As described below, the sampling unit 410 of the transport vehicle 40 continuously measures the position and time of the transport vehicle 40 at a predetermined timing (for example, every minute) using the positioning device 49. The sampling unit 410 generates positioning information indicating the measured position and time (i.e., the measured position and the measured time of the transport vehicle 40).

[0052] The output unit 420 of the transportation vehicle 40 uses the communication device 46 to transmit the positioning information generated by the sampling unit 410 to the farming information management device 10.

[0053] The farming information management device 10 of the farming information management system 1 realizes each of the functions of the information acquisition unit 110, trajectory determination unit 120, deviation determination unit 130, estimation determination unit 140, information output unit 150, and information storage unit 160 shown in Figure 7 by the calculation device 14 of Figure 3 executing program P1.

[0054] The information storage unit 160 stores information for the farming information management device 10 to execute processing. For example, the information storage unit 160 stores positioning information D1 in advance before starting the processing of Figs. 8A to 8B described later. The information storage unit 160 may also store setting information such as thresholds used in the processing described later. The information storage unit 160 may also store a map image of the geographical range in which the working device 30 moves.

[0055] The positioning information D1 stores positioning information indicating the results of one or more work implements 30 and one or more transport vehicles 40 that are the processing targets of the farming information management system 1 continuously measuring their own positions.

[0056] The information acquisition unit 110 of the farming information management device 10 in Fig. 7 acquires information necessary for the processing described below from the information storage unit 160 or an external device (e.g., the terminal device 20, the work device 30, and the transport vehicle 40). The information acquisition unit 110 may acquire multiple pieces of information output by the terminal device 20, for example. The information acquisition unit 110 may provide the acquired information to the trajectory determination unit 120, the deviation determination unit 130, the estimation determination unit 140, the information output unit 150, and the information storage unit 160.

[0057] The trajectory determination section 120 determines the trajectory along which the working device 30 has moved, based on the positioning information of the working device 30 acquired by the information acquisition section 110, as will be described later.

[0058] As described later, the deviation determination unit 130 determines, from among the trajectories determined by the trajectory determination unit 120, a deviation trajectory in which the difference in time or distance between the start point and the end point is greater than a predetermined criterion.

[0059] As described below, the estimation determination unit 140 determines an estimated trajectory along which the working device 30 is estimated to have moved on the deviation trajectory based on the positioning information of the transport vehicle 40 acquired by the information acquisition unit 110 and the positioning positions and positioning times of the start and end points of the deviation trajectory determined by the deviation determination unit 130.

[0060] The information output unit 150 outputs, to the terminal device 20, output information relating to the trajectory determined by the trajectory determination unit 120 and the estimation determination unit 140, as described later.

[0061] The terminal device 20 realizes the functions of the output unit 210 and the display unit 220 shown in FIG. 7 by the arithmetic device 24 in FIG. 4 executing the program P2.

[0062] As described below, based on a user input to display the movement trajectory of the work device 30, the output unit 210 outputs request information indicating that the movement trajectory should be displayed to the farming information management device 10.

[0063] As described below, the display unit 220 displays the movement trajectory of the work device 30 in a manner recognizable by the user, based on output information output by the farming information management device 10.

[0064] Next, the processing executed by the farming information management system 1 will be described. The farming information management system 1 starts the processing shown in Fig. 8A and Fig. 8B when the output unit 210 of the terminal device 20 receives a user input to display the movement trajectory of the working device 30. As an example, the user input to display the movement trajectory of the working device 30 is an input to select a desired working device 30 from one or more working devices 30 displayed on the screen S realized by the input / output device 22 of the terminal device 20, and select an icon to display the movement trajectory of the working device 30.

[0065] In the process of Fig. 8A, first, in step S1002, the output unit 210 of the terminal device 20 outputs request information. For example, in response to a user input to display the movement trajectory of a desired working device 30, the output unit 210 generates request information including information for identifying the working device 30 and information requesting information for displaying the movement trajectory. Then, the output unit 210 outputs this request information to the farming information management device 10 using the communication device 26.

[0066] Next, in step S1004, the information acquisition unit 110 of the farming information management apparatus 10 acquires the request information output in step S1002.

[0067] Next, in step S1006, the information acquisition unit 110 acquires positioning information of the target working apparatus 30 indicated by the request information. For example, the information acquisition unit 110 acquires positioning information D1 from the information storage unit 160, and extracts the positioning information of the target working apparatus 30 from the positioning information D1. Furthermore, when the positioning information D1 includes positioning information of one or more transport vehicles 40 having a function of transporting the working apparatus 30, the information acquisition unit 110 may acquire this position information.

[0068] 3 each time the output unit 320 of one or more working devices 30 outputs its own positioning information. The information acquisition unit 110 may also acquire the positioning information of the transport vehicle 40 each time the output unit 420 of one or more transport vehicles 40 outputs its own positioning information. The information acquisition unit 110 stores the acquired positioning information of the working device 30 and the transport vehicle 40 in positioning information D1 in association with information identifying the working device 30 and the transport vehicle 40 (e.g., identifiers assigned to the working device 30 and the transport vehicle 40).

[0069] Next, in step S1008, the trajectory determination unit 120 determines a movement trajectory of the target working apparatus 30. For example, based on the positioning position and positioning time indicated by the positioning information of the target working apparatus 30 acquired in step S1006, the trajectory determination unit 120 determines a plurality of movement trajectories each connecting two consecutive positioning positions having consecutive positioning times, from the earliest to the latest positioning times of the working apparatus 30. The determined movement trajectory is, for example, a straight line segment having the earlier of the two positioning times as its start point and the latest point as its end point.

[0070] Next, in step S1010, the deviation determination unit 130 determines a deviation trajectory whose start point and end point are separated from each other by more than a predetermined standard in terms of time or distance among the movement trajectories determined in step S1008. For example, the deviation determination unit 130 determines a movement trajectory determined in step S1008 in which the difference in the positioning time between the start point position and the end point position exceeds a predetermined time threshold (e.g., 10 minutes) as a deviation trajectory estimated to be different from the actual path of the working device 30. Alternatively, the deviation determination unit 130 may determine a movement trajectory determined in step S1008 in which the distance between the start point position and the end point position exceeds a predetermined distance threshold (e.g., 1 kilometer) as a deviation trajectory estimated to be different from the actual path of the working device 30.

[0071] Next, in step S1012, the estimation determination unit 140 determines whether or not there is a transport vehicle 40 corresponding to the deviation trajectory determined in step S1010. For example, the estimation determination unit 140 extracts position information of a transport vehicle 40 that can transport the target working device 30 from the positioning information D1 stored in the information storage unit 160. Then, the estimation determination unit 140 determines whether or not there is a transport vehicle 40 that can be estimated to have transported the target working device 30, based on the positioning positions and positioning times of the start point and end point of the deviation trajectory and the positioning position and positioning time of the extracted transport vehicle 40.

[0072] As an example, the estimation determination unit 140 determines whether the positioning information of the transportation vehicle 40 included in the positioning information D1 includes positioning information corresponding to the positioning time and positioning position of the start point and end point of the deviation trajectory. When the positioning information D1 includes positioning information of the same transportation vehicle 40 indicating that the transportation vehicle 40 exists within a predetermined geographical range from the start point and end point positions of the deviation trajectory during a period of a predetermined time difference from the positioning time of the start point and end point of the deviation trajectory, the estimation determination unit 140 determines the transportation vehicle 40 as the transportation vehicle 40 corresponding to the deviation trajectory. In this case, the estimation determination unit 140 determines that the transportation vehicle 40 that transported the target working device 30 exists (step S1012: YES), and then executes step S1014. On the other hand, if the positioning information of the same transport vehicle 40 indicating that the transport vehicle 40 exists within a predetermined geographical range from the positions of the start point and the end point of the deviation trajectory is not included within a period of a predetermined time difference from the positioning times of the start point and the end point of the deviation trajectory, it is determined that the transport vehicle 40 corresponding to the deviation trajectory does not exist (step S1012: NO). In this case, step S1016 in FIG. 8B is executed next.

[0073] In step S1014 of FIG. 8A, the estimation determination unit 140 determines an estimated trajectory that is estimated to correspond to the route that the working device 30 actually moved from the start point to the end point of the estimated trajectory based on the positioning information of the transport vehicle 40 corresponding to the deviation trajectory determined in step S1012. For example, the estimation determination unit 140 extracts the positioning information of the transport vehicle 40 corresponding to the deviation trajectory, which corresponds to a period of a predetermined time difference from the positioning times of the start point and the end point of the deviation trajectory, from the positioning information D1. Then, the estimation determination unit 140 determines a plurality of straight line segments that connect two points with consecutive positioning times among the positions indicated by the extracted positioning information of the transport vehicle 40. The estimation determination unit 140 determines each of the determined plurality of line segments as an estimated trajectory. When step S1014 is completed, step S1016 is executed next.

[0074] In step S1016 of Fig. 8B, the trajectory determination unit 120 generates trajectory information D2. The trajectory information D2 generated by the trajectory determination unit 120 includes information indicating the measured positions and the measured times of the start and end points of each of the movement trajectories of the target working apparatus 30 determined in step S1008 of Fig. 8A. For example, as shown in Fig. 9, the trajectory information D2 includes a "trajectory ID" indicating an identifier of a plurality of movement trajectories, a "first position" and a "second position" indicating the positions of the start and end points of the movement trajectories, respectively, and a "type" indicating the type of the movement trajectory. As an example, the "first position" and the "second position" indicate coordinates (e.g., latitude and longitude) indicating the geographical positions of the start and end points of the movement trajectory. In the "type", "deviation" is stored if the movement trajectory is a divergent trajectory determined in step S1010 of FIG. 8A, and "normal" is stored if the movement trajectory is another trajectory (also called a normal trajectory). In addition, the trajectory information D2 may include information indicating the estimated trajectory determined in step S1014 of FIG. 8A. In the example of FIG. 9, the row in which "estimated" is stored in "type" (the row in which "trajectory ID" is "k+1") indicates the estimated trajectory.

[0075] 8B, the information output unit 150 outputs output information including the trajectory information D2 generated in step S1016. For example, the information output unit 150 uses the communication device 16 to output output information including the trajectory information D2 and a map image including the geographical positions indicated by the "first position" and the "second position" of the trajectory information D2 to the terminal device 20.

[0076] Next, in step S1020, the display unit 220 of the terminal device 20 displays the movement trajectories indicated by the output information output in step S1018. For example, the display unit 220 may display one or more movement trajectories included in the output information on the screen S of the display device of the input / output device 22 of the terminal device 20, superimposed on a map image in a mode according to the type of the movement trajectory indicated by the "type" of the trajectory information D2.

[0077] For example, as shown in FIG. 10, the display unit 220 displays a normal trajectory in which "normal" is stored in the "type" of the trajectory information D2 in FIG. 9 with a thick solid line. For example, as shown in FIG. 10, the display unit 220 displays a plurality of normal trajectories (in the example of FIG. 2, movement trajectories L_1 to movement trajectory L_m-1) constituting the route R1 when working in the field F1 and a plurality of normal trajectories (in the example of FIG. 2, movement trajectories L_m+1 to movement trajectory L_n-1) constituting the route R2 when working in the field F2 with a solid line. On the other hand, as shown in FIG. 10, the display unit 220 displays a deviation trajectory (for example, movement trajectory L_m) in which "deviation" is stored in the "type" of the trajectory information D2 with a dotted line thinner than the normal trajectory. In this way, the display unit 220 may display the deviation trajectory in a manner that is less visible to the user than the normal trajectory.

[0078] The display unit 220 may display a user interface that allows the user to select a manner of displaying the deviation trajectory, such as the selection form SF in Fig. 10. The selection form SF includes radio buttons corresponding to three options, namely, displaying the deviation trajectory as a dotted line, displaying the estimated trajectory as a dotted line instead of the deviation trajectory, and not displaying the deviation trajectory. In the example of Fig. 10, the movement trajectory L_m, which is the deviation trajectory, is displayed as a dotted line in response to the radio button with the text "display as dotted line" indicating that the deviation trajectory is displayed as a dotted line being selected.

[0079] When the user selects a radio button indicating that an estimated trajectory is to be displayed, which is indicated by the text "Display Estimated Route" in the selection form SF, the display unit 220 displays a screen as shown in Fig. 11. In the example of Fig. 11, the display unit 220 switches from the display mode of Fig. 10 to display an estimated route Re including one or more estimated trajectories in dotted lines. At this time, the display unit 220 displays an estimated trajectory in which "Estimate" is stored in the "Type" of the trajectory information D2 in dotted lines, instead of the deviation trajectory in which "Deviation" is stored in the "Type" of the trajectory information D2 in Fig. 9. Note that the display unit 220 may display the estimated trajectory in addition to the deviation trajectory.

[0080] When a radio button indicating that the deviation trajectory should be hidden and marked with the text “Hide” is selected in the selection form SF, the display unit 220 displays to the user a screen that has been switched to a mode in which the normal trajectory is displayed but the deviation trajectory is not displayed, as shown in FIG. 12.

[0081] As described above, the farming information management system 1 displays deviation trajectories based on positioning information that are geographically or temporally distant beyond a standard set by the settings in a manner different from other normal trajectories. Alternatively, the normal trajectories are displayed in a manner that is visible to the user, while deviation trajectories are not displayed. Therefore, the farming information management system 1 can display movement trajectories in a manner that is less likely to cause suspicion to the user.

[0082] (Modification) The configurations described in the embodiments are merely examples, and the configurations can be changed without impairing the functions.

[0083] For example, one or more of the information acquisition unit 110, the trajectory determination unit 120, the deviation determination unit 130, the estimation determination unit 140, the information output unit 150, and the information storage unit 160 of the farming information management device 10 may be realized in a distributed manner by two or more computers. Also, for example, one or more of the functions of the farming information management device 10 may be included in the terminal device 20.

[0084] In addition, when the operation information of the working device 30 or the transport vehicle 40 can be obtained from an external device (for example, an external server device that accumulates operation information), the information acquisition unit 110 may acquire the operation information from this external device instead of the working device 30 or the transport vehicle 40. In this case, the farming information management system 1 does not need to include the working device 30 or the transport vehicle 40. In addition, the farming information management device 10 may have a functional unit corresponding to the output unit 210 and the display unit 220 of the terminal device 20. In this case, the functional unit corresponding to the display unit 220 may display the movement trajectory in the manner indicated by the trajectory information D2 on the screen of the display device of the input / output device 12 of the farming information management device 10 in step S1020 of FIG. 8B. In this case, the farming information management system 1 does not need to include the terminal device 20.

[0085] In addition, the processing executed by the farming information management system 1 may be different from the processing described in FIG. 8A and FIG. 8B. For example, the estimation determination unit 140 may determine the estimated trajectory in a manner different from that of the above embodiment. For example, when road information is available for a geographical range including the deviation trajectory, the estimation determination unit 140 may determine the estimated trajectory based on the road information. As an example, in step S1014 of FIG. 8A, the information acquisition unit 110 acquires road information indicating roads that the working device 30 (or the transport vehicle 40) can travel in a geographical range including the start point and the end point of the deviation trajectory. Note that in this modified example, the processing in step S1012 is not performed, and the above processing is performed regardless of the presence or absence of the transport vehicle 40 corresponding to the deviation trajectory. Then, in step S1014, the estimation determination unit 140 may further determine, as the estimated trajectory, a route that connects the start point position to the end point position of the deviation trajectory in the shortest distance using a known route determination algorithm such as Dijkstra's algorithm. Alternatively, if a route search service that outputs a recommended route from the starting point to the destination when information indicating the starting position and the destination is input is available, the estimation determination unit 140 may determine the estimated trajectory using this route search service. In this case, the estimation determination unit 140 outputs information indicating the starting point of the deviation trajectory as the starting position and the end point as the destination to a server that provides the route search service. Then, the estimation determination unit 140 may determine the recommended route output by the server as the estimated trajectory.

[0086] Furthermore, when there is positioning information of a plurality of working apparatuses 30 (e.g., a plurality of working apparatuses 30 owned by a user) including the target working apparatus 30, the estimation determination unit 140 may determine the estimated trajectory based on this positioning information. For example, in step S1012 of FIG. 8A, the estimation determination unit 140 determines the working apparatus that has moved from the starting point to the end point of the deviation trajectory as a specific working apparatus 30 corresponding to the deviation trajectory based on the positioning information D1. As an example, the estimation determination unit 140 extracts pairs of position information included in the positioning information D1, the pair of position information indicating a position within a predetermined error range from the starting point position and the pair of position information indicating a position within a predetermined error range from the end point position, which are measured within a predetermined period (e.g., one day). Then, when there is position information of a working apparatus 30 of the same machine among the pairs of extracted position information, the estimation determination unit 140 determines the working apparatus 30 as the working apparatus 30 corresponding to the deviation trajectory. Then, in step S1014, similarly to the case of the transfer vehicle 40, the estimation determination unit 140 may determine an estimated trajectory based on the positioning information of the working device 30 corresponding to the determined deviation trajectory.

[0087] In addition, the trajectory determination unit 120 may not determine the movement trajectory using all the positioning information measured by the working device 30. For example, when the amount of information is large, such as when the positioning device 19 performs positioning frequently (for example, every second), the trajectory determination unit 120 may determine the movement trajectory using the movement trajectory filtered by a predetermined criterion. In this case, for example, in step S1006 of FIG. 8A, the information acquisition unit 110 acquires positioning information (for example, positioning information measured at an even number of times among the positioning information) filtered by a predetermined criterion from the positioning information of the target working device 30 included in the positioning information D1. Then, in step S1008, the trajectory determination unit 120 may determine, as the movement trajectory, a position connecting two points with consecutive positioning times among the positioning information thinned out from the initial positioning by this filtering.

[0088] Furthermore, the display unit 220 may display the deviation trajectory in a manner different from that described in the above embodiment. For example, the display unit 220 may display the deviation trajectory with a character or symbol (e.g., the character "Route during non-positioning period" or the symbol "?") indicating that the deviation trajectory may differ from the actual moving route. Also, a configuration may be adopted in which the display unit 220 does not display the deviation trajectory. In this case, the information output unit 150 may output output information that does not include the deviation trajectory in step S1018 of FIG. 8B.

[0089] The deviation determination unit 130 may also determine the deviation trajectory based on both the positioning position and the positioning time indicated by the positioning information. For example, in step S1010 of FIG. 8A, the deviation determination unit 130 may determine, as a deviation trajectory, a movement trajectory in which the positioning positions of the start point and the end point are farther apart than a predetermined distance threshold and the positioning times are farther apart than a predetermined time threshold, among the movement trajectories determined in step S1008. In this case, even if the start point and the end point are far apart in position, if the positioning times are closer than the time threshold, the deviation determination unit 130 determines the movement trajectory as a normal trajectory. In this case, the farming information management system 1 can avoid determining, as a deviation trajectory, a movement trajectory that is farther apart in distance due to a temporary positioning error. In addition, even if the positioning times of the start point and the end point are far apart, if the positioning positions are closer than the distance threshold, the deviation determination unit 130 determines the movement trajectory as a normal trajectory. In this case, the farming information management system 1 can avoid determining a movement trajectory that is temporally deviated due to a non-positioning period caused by work interruption, etc., as a deviation trajectory.

[0090] The above-described embodiments and modifications are merely examples, and the configurations described in each embodiment may be modified and / or combined as desired without impairing the functions. Furthermore, some of the functions described in the embodiments may be omitted as long as the necessary functions can be realized.
