Hereinafter, an agricultural management support system according to an embodiment of the present invention will be described with reference to the drawings.
[First Embodiment]
The agricultural management support system of the present invention manages agricultural machines that perform agricultural work, workers that perform agricultural work, and the like using satellite positioning systems (Global Positioning System, Galileo, GLONASS, etc.).

As shown in FIG. 1, an agricultural management support system 1 is provided with a machine position detection device 3 mounted on an agricultural machine 2 such as a tractor, a combine, a rice transplanter, and a worker position detection device 4 possessed by the worker. And a device 5.
The machine position detection device 3 obtains the position (machine position) of the agricultural machine 2 on the basis of the signal from the positioning satellite 6, and the worker position detection device 4 is based on the signal from the positioning satellite 6. Worker position). The machine position and the worker position are input to the providing device 5 by wireless communication. Based on the input machine position and worker position, the providing device 5 determines the state of the farm machine 2 after the farm work and the farm work of the worker, or both the farm machine 2 and the worker U after the farm work. It provides the status of agricultural work.

Hereinafter, the agricultural management support system 1 will be described in detail.
The agricultural machine 2 is capable of performing various farm work while moving in a farm field, and is provided with a work device 7 for performing the farm work. As described above, the agricultural machine 2 includes a tractor, a combiner, and a rice transplanter. However, any agricultural machine 2 may be used as long as it can be self-propelled and can perform agricultural work.

The machine position detection device 3 is attached to a traveling vehicle body or the like of the agricultural machine 2. The machine position detection device 3 receives, for example, a signal (GPS satellite position, transmission time, correction information, etc.) transmitted from a positioning satellite (for example, GPS satellite) 6, and based on the received signal, the machine position ( For example, latitude and longitude) are detected. The machine position obtained by the machine position detection device 3 can be transmitted to the outside via the communication device 10 mounted on the agricultural machine 2. When transmitting the machine position, the communication device 10 also transmits agricultural machine specifying information for specifying (identifying) the agricultural machine 2. It is desirable that the machine position detection device 3 associates the time when the machine position is detected with the machine position and transmits the associated machine position and time to the providing device 5 as well.

  The worker position detection device 4 is configured to have a size that can be easily carried by the worker. For example, the worker position detection device 4 is a portable device such as a smartphone (multifunctional mobile phone), a tablet PC, or a small laptop computer having a relatively high computing ability. It is mounted on a terminal (portable computer) 11. The worker position detection device 4 receives a signal (GPS satellite position, transmission time, correction information, etc.) transmitted from a positioning satellite (for example, GPS satellite) 6 in the same manner as the machine position detection device 3. Based on the received signal, its own position (for example, latitude and longitude), that is, the worker position of the worker who brought the mobile terminal 11 is detected. The worker position obtained by the worker position detection device 4 can be transmitted to the outside (providing device 5 described later) via the communication device 12 mounted on the portable terminal 11. When transmitting the worker position, the communication device 12 also transmits worker specifying information for specifying (identifying) the mobile terminal 11 (worker). It is desirable that the worker detection device 5 associates the time at which the worker position is detected with the worker position and transmits the associated worker position and time to the providing device 5.

The providing device 5 is composed of a server arranged on the network. The server 5 can receive various information transmitted from the communication device 10 of the agricultural machine 2 and can receive various information transmitted from the communication device 12 of the mobile terminal 11.
As described above, the server 5 can be accessed by the portable terminal 11 held by the worker and the installation type computer (for example, personal computer) 9 installed by the worker on the farmer or the like separately from the portable terminal 11. If the server 5 is accessed using the stationary computer 9, various information stored in the first storage unit 13 of the server 5 can be taken into the stationary computer 9. The server 5 is installed in a management company that manages agricultural work in various regions, a manufacturing company that manufactures agricultural machinery such as the tractor 2 or provides agricultural machinery services, and collectively manages agricultural work in each region. Is desirable.

The server 5 includes a first storage unit 13 configured from a non-volatile memory or the like, a calculation unit 14 configured from a CPU or the like, and a display unit 15 configured from a monitor or the like.
The 1st memory | storage part 13 memorize | stores various information regarding farm work, for example, various information (the machine position, the time linked | related with the machine position, agricultural machine specific information transmitted from the communication apparatus 10 of the agricultural machine 2). ), Various information transmitted from the communication device 12 of the portable terminal 11 (worker position, time associated with the worker position, worker identification information), map information of the farm field where the farm work is performed, and a calculation unit as described later The result calculated in 14 is stored.

  The calculation unit 14 performs various processes and includes a collation unit 16 and a state determination unit 17. The collation unit 16 obtains the agricultural machine trajectory (agricultural machine trajectory) obtained by using the plurality of machine positions stored in the first storage unit 13 and the plurality of worker positions stored in the first storage unit 13. The operator's trajectory (worker trajectory) obtained by use is collated. The calculation of the agricultural machine trajectory and the worker trajectory is performed by the calculation unit 14. For example, the agricultural machine trajectory is obtained by continuously connecting plot points of each machine position arranged in time series to form a line drawing or the like. Further, the worker trajectory is also obtained by continuously connecting plot points at respective worker positions arranged in time series to form a line drawing or the like. Any method may be used to calculate the agricultural machine trajectory and the worker trajectory.

  When the collating unit 16 collates the agricultural machine trajectory with the worker position, the state determining unit 17 determines that the worker has boarded the agricultural machine while the agricultural machine trajectory and the worker trajectory overlap. The judgment result is output. In addition, the state determination unit 17 determines and determines that the worker trajectory, where the agricultural machine trajectory and the worker trajectory do not overlap, has been performed by the worker without riding the agricultural machine 2. Output the result.

FIG. 2 exemplarily shows an agricultural machine trajectory of one agricultural machine that has performed an agricultural work and an operator trajectory of one worker who has performed the agricultural work. The collation unit 16 and the state determination unit 17 will be described in detail based on the example of FIG.
As shown in FIG. 2, the agricultural machine trajectory Q1 of the agricultural machine 2a travels along the outer peripheral edge (right side) 21 on the right side of the field from the entrance 20 of the field, and slightly toward the center side of the field on the opposite side to the entrance 20. It is assumed that the state is a meandering state in which a U-turn is made while shifting and proceeds toward the outer peripheral edge (upper side) 22 on the inlet 20 side and a U-turn is made on the upper side 22.

  On the other hand, the worker trajectory Q2 of the worker proceeds from the farm entrance 20 along the outer peripheral edge (right side) 21 of the farm field in the same manner as the agricultural machine trajectory Q1, and slightly shifts to the center side of the farm field on the opposite side to the entrance 20. However, while making a U-turn and proceeding toward the upper side 22, it proceeds toward the side opposite to the upper side 22 (entrance side 20) on the way and reaches the outer peripheral edge (lower side) 23 on the lower side opposite to the entrance 20. After traveling along, it will return to the meandering state in substantially the same way as the agricultural machine trajectory Q1.

When the computing unit 14 of the server 5 obtains the agricultural machine trajectory Q1 and the worker trajectory Q2 after the farm work, the collating unit 16 superimposes the agricultural machine trajectory Q1 and the worker trajectory Q2.
In the section from the point P1 to the point P2 close to the entrance 20, the state determination unit 17 indicates that the agricultural machine trajectory Q1 and the worker trajectory Q2 substantially coincide with each other, so the agricultural machine trajectory Q1 and the worker trajectory Q2 overlap. From this point P1 to point P2, it is determined that the worker has boarded the agricultural machine 2a and performed work. Then, for example, as shown in FIG. 3, the state determination unit 17 adds a boarding flag indicating that the boarding is started at the point P <b> 1 at the beginning of overlapping to a machine position or an operator position corresponding to the point P <b> 1. In other words, the machine position or worker position corresponding to the point P1 is associated with the boarding flag. Moreover, the state determination part 17 adds the getting-off flag which shows having got off at the point P2 used as the end of overlap to the machine position and worker position corresponding to the point P2.

  That is, in the overlapping section where the agricultural machine trajectory Q1 and the worker trajectory Q2 overlap, the state determination unit 17 sets the boarding flag at the machine position or worker position corresponding to the point P1 that is the beginning of the overlapping section. Associate. In addition, in the overlapping section that is overlapped, the getting-off flag is associated with the machine position or the worker position corresponding to the point P2 that is the end of the overlapping section.

  It should be noted that only when the agricultural machine trajectory Q1 and the worker trajectory Q2 are completely coincident with each other, the agricultural machine trajectory Q1 and the worker trajectory Q2 are not determined to overlap, but are duplicated in the state determination unit 17. The permissible width (permissible deviation width, permissible distance) when performing the determination is set in advance, and the state determination unit 17 determines that the deviation width between the agricultural machine trajectory Q1 and the worker trajectory Q2 is preset. If it is within the range, it is determined that there is an overlap. For example, the allowable width is set to the width of the traveling vehicle or the width of the work device 7 in the agricultural machine 2.

  Moreover, the state determination part 17 tracks the worker locus | trajectory Q2 of the worker of point P2 transfer, and determines whether it overlaps with the agricultural machine locus | trajectory Q1 of the agricultural machine 2a. The state determination unit 17 is a point P2 transition, and since the agricultural machine trajectory Q1 and the worker trajectory Q2 substantially coincide in the section from the point P3 to the point P4, the work from the point P3 to the point P4 is performed. It is determined that the person got on the agricultural machine 2a and worked. Similarly to the points P1 and P2 described above, the state determination unit 17 adds a boarding flag to the machine position and the worker position corresponding to the point P3, and also sets a getting-off flag to the machine position and the worker position corresponding to the point P4. Append.

Furthermore, the state determination part 17 is a part except the overlap area where it was supposed to get on the agricultural machine 2a among all the worker locus | trajectories Q2 (trajectory to the point P1-point P4) of an operator, ie, point P2-. It is determined that the section up to the point P3 has been farmed without getting on the agricultural machine 2a. Then, for example, as shown in FIG. 3, the state determination unit 17 sets a work flag indicating that the farm work has been performed other than the agricultural machine at the worker position of the point P2 transition that is assumed to have been performed without riding. Append. In other words, the worker position at the point P2 shift is associated with the work flag. Note that the above-described boarding flag (start flag), getting-off flag (end flag), and work flag are preferably stored in the first storage unit 13 together with the machine position and the worker position.

The server 5 displays the result determined by the state determination unit 17 on the display unit 15.
As shown in FIG. 4A, for example, an agricultural field map G on which an agricultural machine and an operator performed farm work is read from the map information stored in the first storage unit 13 and displayed on the display unit 15. In addition, the display unit 15 displays the agricultural machine trajectory Q1 and the worker trajectory Q2 superimposed on the agricultural field map G, and starts positions P1, P3 and end positions P2, where the agricultural work has been performed by getting on the agricultural machine. P4 is displayed on the field map G. The detection of the start position and the end position is performed based on the presence or absence of a boarding flag or a getting-off flag associated with the machine position or the worker position. Furthermore, the section where the worker did the farm work without getting on the agricultural machine 2 is displayed by, for example, making the worker locus Q2 a two-dot chain line.

  Alternatively, the server 5 may display the result determined by the state determination unit 17 on the display unit 15 as shown in FIG. As shown in FIG. 4B, for example, the display unit 15 displays the field name indicating the field where the farm machine and the worker performed the farm work, the type of the farm machine, and the worker name. The field name may be input by the operator, or may be automatically detected by comparing the map information with the machine position or the worker position. The type of the agricultural machine may be input by the operator, or may be detected based on the agricultural machine specifying information transmitted from the agricultural machine 2. The worker name may be input by the worker, or may be detected based on the worker identification information transmitted from the mobile terminal 11.

  The server 5 searches the first storage unit 13 for the machine position corresponding to the boarding flag (position at the time of boarding) and the machine position corresponding to the boarding flag (position at the time of getting off), and each position (latitude, Longitude) is displayed on the display unit 15. Further, the server 5 searches the first storage unit 13 for the worker position at which the worker starts the work and the worker position at the end of the work based on the work flag, and displays them.

Each position shown in FIG. 3B may be replaced with time and displayed as shown in FIG.
The server 5 extracts the time corresponding to the machine position of the boarding flag (time at the time of boarding) and also extracts the time corresponding to the machine position of the getting off flag (time at the time of getting off). Then, the server 5 displays the time of getting on and the time of getting off on the display unit 15. Further, the server 5 obtains the worker position at which the worker starts work based on the work flag, and extracts the time (work start time) corresponding to this worker start worker position. Further, the server 5 obtains the worker position at the end of the work by the worker based on the work flag, and extracts the time (work end time) corresponding to the worker position at the end of the work. Then, the server 5 displays the time at the start of work and the time at the end of work on the display unit 15.

  According to the above, since the server 5 can provide the relationship between the machine position detected by the machine position detection device 3 and the worker position detected by the worker position detection device 4, the situation (motion of the agricultural machine that performed the farm work) ) And the situation (movement) of the worker. In particular, the agricultural machine trajectory Q1 obtained at the machine position is compared with the worker trajectory Q2 obtained at the worker position, and an overlapping section in which the agricultural machine trajectory Q1 and the worker trajectory Q2 are overlapped by the state determination unit 17 is obtained. Since it is determined that the worker has worked on the agricultural machine, it is easily grasped by the information of the trajectory after the completion of the agricultural work, even if the worker does not record the details of the position and time when the agricultural machine was boarded. can do. Moreover, the presence or absence of boarding can be confirmed without providing the confirmation apparatus which confirms the presence or absence of a boarding of an operator in the agricultural machine side. Even if a confirmation device is provided separately, even if the operator forgets confirmation of the confirmation device, boarding can be confirmed after farming.

In addition, it is possible to grasp the place where the worker performed farm work without getting on the agricultural machine 2. When a plurality of workers cooperate to perform farm work, it is possible to separately grasp a worker who performed farm work by hand and a worker who performed farm work by the agricultural machine 2.
In the above-described embodiment, the result determined by the state determination unit 17 is displayed on the display unit 15, but the calculation unit 14 obtains from the machine position without providing the collation unit 16 and the state determination unit 17. The agricultural machine trajectory Q1 and the worker trajectory Q2 obtained from the worker position may be displayed on the same screen by the display unit 15. Further, as a result of the determination by the state determination unit 17 that can be displayed on the display unit 15 of the server 5, the agricultural machine trajectory Q <b> 1, the worker trajectory Q <b> 2, and the agricultural field map are displayed on the display unit ( For example, it may be displayed on a display monitor.
[Second Embodiment]
In the second embodiment, as shown in FIG. 5, the data collection device 25 that collects the agricultural work data when the agricultural work is performed by the agricultural machine 2 is mounted on the agricultural machine 2, and the agricultural work data collected by the data collecting device 25 is used. Is transmitted to the server 5. A configuration different from the first embodiment will be described. In the second embodiment, a tractor will be described as an example of an agricultural machine in order to make it easy to understand the collection of farm work data by the data collection device 2. As a matter of course, the agricultural machine may be a combiner other than a tractor, a rice transplanter, or the like.

  As shown in FIG. 8, the tractor 2 is configured by mounting an engine 31, a transmission device 32, and the like on a traveling vehicle (traveling vehicle body) 30 with wheels attached to the front and rear. An independently mounted cabin 33 is provided behind the engine 31, and a driver's seat 34 is provided in the cabin 33. In addition, a three-point link mechanism 35 is provided at the rear portion of the traveling vehicle 30 so as to be movable up and down, and a PTO shaft that transmits power from the engine 31 is provided. A working device 7 such as a fertilizer application device, a tilling device, an agrochemical application device, a seeding application device, and a harvesting device is detachably attached to the three-point link mechanism 35. FIG. 8 shows an example in which the fertilizer application device is attached to the three-point link mechanism 15.

  In addition to the data collection device 25, the tractor 2 is equipped with a control device. This control device performs traveling system control and work system control of the tractor 2 and controls the operation of the engine as the traveling system control, and the operation provided around the driver's seat as the working system control. When an input from an operation tool such as a lever or an operation switch is received, operations such as raising and lowering of the three-point link mechanism 15 and output (rotation speed) of the PTO shaft are controlled according to the input value. Control signals for performing traveling system control and work system control of the tractor 2 and various detection signals for performing the control (for example, signals detected by the sensors) are output to the vehicle communication network and are transmitted to each part of the tractor 2. Communicated. The travel system control and work system control by the control device are not limited to those described above.

  The data collection device 25 automatically collects various data related to farm work when the tractor 2 is operating via a vehicle network to which various sensors, control devices, and the like are connected. For example, when a cultivator is connected to the rear part of the tractor 2 as the working device 7 and the tractor 2 is operated, data such as the rotational speed of the rotary, the load of the rotary, the engine rotational speed, the vehicle speed, and the tilling depth are stored in the vehicle communication network. Is output. The data collection device 25 acquires data such as rotary speed, rotary load, engine speed, vehicle speed, and tilling depth as farm work data.

  In addition, when the work device 7 is a fertilizer spraying device, a pesticide spraying device, or a seeding spraying device, data such as vehicle speed, engine speed, spraying amount (fertilizer spraying amount, pesticide spraying amount, seeding spraying amount) is transmitted in the vehicle communication network The data collection device 3 outputs the vehicle speed, the engine speed, the fertilizer application amount, the agricultural chemical application amount, and the seeding application amount as agricultural work data. Alternatively, when the work device 7 is a harvesting device, data such as the vehicle speed, the engine speed, and the harvest amount are output on the vehicle communication network, and the data collection device 3 uses the farm speed data for the vehicle speed, the engine speed, and the harvest amount. Acquired as (agricultural work result information).

  In addition, the data collection device 25 includes a second storage unit (buffer) 50 that temporarily stores various information. The second storage unit 50 stores farm work data (farm work result information), a machine position obtained by the machine position detection device 3, a time when the machine position is detected, and farm machine identification information. These pieces of information are sequentially stored in the second storage unit 50 every time the agricultural machine 2 moves or every time the agricultural machine 2 operates. In addition, it is desirable that the farm work performance information and the machine position and time are stored in the second storage unit 50 in association with each other.

The communication device 10 transmits the farm machine side information (farm performance information, machine position, time, farm machine identification information) stored in the second storage unit 50 to the server 5 at predetermined intervals.
When the server 5 receives the agricultural machine side information transmitted from the communication device 10 of the tractor (agricultural machine) 2, the server 5 stores the received agricultural machine side information in the first storage unit 13. On the other hand, when mobile side information (worker position, worker identification information) transmitted from the communication device 12 of the mobile terminal 11 is received, the mobile side information is stored in the first storage unit 13.

  According to the above, after providing the data collection device 25 that collects the farm work result information when the farm machine 2 performs the farm work, among the farm machine side information, at least the farm work result information and the machine position are stored in the first of the server 5. Since the information is stored in the storage unit 13, the farm work result information and the machine position stored in the first storage unit 13 are displayed, analyzed, etc., and the contents of the farm work performed on the agricultural machine 2 and the machine position at that time Can be grasped. Furthermore, since the worker position is also stored in the first storage unit 13 of the server 5, in addition to displaying and analyzing the farm work related to the agricultural machine 2, it is possible to grasp the movement of the worker during the farm work.

That is, after the workers have completed the farm work using the farm machine, the farm machine 2 and the worker U at the time of the farm work are performed by performing analysis based on the farm machine side information and the mobile side information stored in the server 5. In addition to the movements, it is possible to easily grasp the actual contents of farm work.
For example, when the farm work performance information is a harvest amount, the computing unit 14 of the server 5 extracts the machine position associated with the harvest amount from the first storage unit 13, and based on the extracted machine position, The movement trajectory can be displayed on the display unit 15. In addition, the computing unit 14 of the server 5 extracts the machine position in one field, extracts the machine position associated with the harvest amount from the extracted machine position, and associates the machine position with the extracted machine position. By summing the harvested amounts, the harvested amount for each field can be calculated. In addition, the analysis of the farm work by the farm work performance information described above is an example and may be analyzed in any way. Moreover, since the agricultural performance information includes not only the yield but also various information, the agricultural performance information to be used may be selected as appropriate depending on the content to be analyzed.

Moreover, in this embodiment, since farm work performance information can be memorize | stored in the 1st memory | storage part 13 of the server 5, it is stored in the server 5 (1st memory | storage part 13) using the installation type computer 9 etc. which were installed in the farmer. Access and organize farm work results information on the server 5 or the installed computer 9 to create daily work reports, work plans, graphs of farm work results for each field, and management plans. it can.
[Third Embodiment]
As shown in FIG. 6, in the third embodiment, when transmitting the farm work performance information collected by the data collection device 25 to the server 5, the farm work performance information is transmitted via the portable terminal 11 equipped with the worker position detection device 4. This is transmitted to the server 5. A configuration different from the above-described first and second embodiments will be described.

  As shown in FIG. 6, the communication device 10 performs short-range wireless communication. For example, the communication device 10 communicates with the portable terminal 11 by Wi-Fi (Wireless Fidelity, registered trademark) of the IEEE 802.11 series that is a communication standard. Wireless communication is executed. The communication device 10 transmits agricultural machine side information (agricultural work performance information, machine position, time, agricultural machine identification information) to the mobile terminal 11.

  On the other hand, the communication device 12 of the portable terminal 11 performs short-distance wireless communication like the communication device 10, and is, for example, a data collection device according to Wi-Fi (registered trademark) of the IEEE 802.11 series that is a communication standard. 25 to perform wireless communication. In addition, the communication device 12 has a function of transmitting various information to the server 5 via a mobile communication network (for example, a mobile phone communication network).

  When the wireless communication connection between the data collection device 25 and the portable terminal 11 is executed, the communication device 10 of the data collection device 25 transmits the agricultural machine side information stored in the second storage unit 50 to the portable terminal 11. . When the communication device 12 of the portable terminal 11 receives the transmitted agricultural machine side information from the data collection device 25, the communication device 12 stores the information in the third storage unit 51 provided in the portable terminal 11. The third storage unit 51 also stores the worker position and worker identification information detected by the worker position detection device 4, that is, portable information.

When the communication device 12 of the mobile terminal 11 is in the communication area of the mobile communication network and can be connected to the server 5, it transmits the agricultural machine side information and the mobile side information stored in the third storage unit 51.
On the other hand, the server 5 receives the agricultural machine side information and the portable side information via the portable terminal 11, and stores the received agricultural machine side information and the portable side information in the first storage unit 13.
According to the above, at least the work performance information collected by the data collection device 25 and the machine position obtained by the machine position detection device 3 are received by the portable terminal 11, and at least the work performance information among these farming machine side information. Since the machine position and the worker position of the portable information are transmitted to the server 5 configured by the server, the mobile terminal 11 that has performed the farm work transmits data necessary for the analysis and display of the farm work to the server 5.

  In the above-described embodiment, the providing device 5 is configured by the server, but may be configured by the mobile terminal 11. Specifically, as shown in FIG. 7, the mobile terminal 11 is provided in the worker position detection device 4, and includes a first storage unit 13, a calculation unit 14 (collation unit 16, state determination unit 17), And a display unit 15. The portable terminal 11 can receive the agricultural machine side information (agricultural work performance information, machine position, time, agricultural machine identification information) from the data collection device 25, and the received agricultural machine side information is stored in the first storage unit 13. It has become so. In addition, the worker position and worker identification information detected by the worker position detection device 4 are also stored in the first storage unit 13. Similar to the server 5 described above, the operation of the computing unit 14 (verification unit 16 and state determination unit 17) of the portable terminal 11 collates the agricultural machine trajectory Q1 with the worker trajectory Q2, and compares the agricultural machine trajectory Q1 with the work. It is determined that the worker has worked on the agricultural machine in the overlapping section where the worker trajectory Q2 overlaps, or the worker trajectory excluding this overlapping section is used for the farm work without the worker riding on the agricultural machine 2. The result of the determination is displayed in the same manner as the server 5. Detailed processing in the calculation unit 14 of the mobile terminal 11 is the same as that of the server 5, and thus description thereof is omitted. The providing device 5 may be configured by an installed computer 9 installed in a farmer or the like instead of the mobile terminal 11.

  In embodiment mentioned above, the calculating part 14 (collation part 16 and the state judgment part 17) is provided in the provision apparatuses 5, such as a server and a portable terminal, A collation part 16 collates an agricultural machine locus | trajectory with an operator locus | trajectory, Although the state determination unit 17 determines whether or not the worker is on the agricultural machine, the providing device 5 determines the machine position (agricultural machine locus) stored in the first storage unit 13 of the providing device 5. ) And the worker position (worker trajectory) may be displayed on the display unit 15 in an overlapping manner. That is, since the display unit 15 of the providing device 5 displays the machine position and the contractor position in an overlapping manner, it is possible to grasp the positional relationship between the machine position and the worker position.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
