Time refers to a point in time using at least one of “hour”, “minute”, “second”, but indicates time using “year”, “month”, “day” It may be.
[First Embodiment]
The work management system of the present invention is a system that can manage the work of workers and work machines that have performed work in a work place. This work management system performs various management of, for example, a worker who performed farm work in a farm field (work field) where crops and the like are grown, or an agricultural machine (work machine) that performed farm work in a farm field. Hereinafter, for convenience of explanation, a work management system will be described with a work field as a farm field, a work as a farm work, and a work machine as an agricultural machine.

As shown in FIG. 1, the work management system 1 includes a data collection device 3 mounted on an agricultural machine 2 such as a tractor, a combiner, and a rice transplanter, a portable terminal 4 possessed by an operator during farm work, and work management support. A device 5 is provided.
The data collection device 3 collects operation information when the agricultural machine 2 is operated. For example, the operation information related to farm work such as load information (speed, engine speed), fertilizer application amount, harvest amount, etc. Collect as farm work data. The contents (items) collected as farm work data are set in advance in the data collection device 3 or the like.

  The data collection device 3 includes a communication device 31 that performs wireless communication. The communication apparatus 31 can perform wireless communication such as IEEE 802.11 series Wi-Fi (registered trademark), which is a communication standard. Therefore, the data collection device 3 can acquire the farm work data output from the agricultural machine 2 during the farm work and transmit the collected farm work data to the outside by wireless communication using Wi-Fi.

  In addition, as for the communication apparatus 31, it is desirable to transmit the working machine specific information for specifying (identifying) the agricultural machine 2 outside. The work machine identification information may be any information as long as it identifies a work machine that performs an operation such as an agricultural machine, such as a manufacturing number, a model, a model number, and the like. When the work machine specifying information is transmitted together with the farm work data in this way, it is possible to identify which farm machine 2 is the farm work data.

The mobile terminal 4 is, for example, a portable computer such as a smart phone (multifunctional mobile phone) or a tablet PC having a relatively high computing ability. The portable terminal 4 is provided with various assistances (support) in farm work by being held by the worker during farm work.
Specifically, the mobile terminal 4 includes a position detection device 40 that detects its own position (self-position) by a satellite positioning system (Global Positioning System, Galileo, GLONASS, etc.). The position detection device 40 receives 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 position (for example, latitude) , Longitude). The position detection device 40 also obtains a detection time when the self-position is detected based on a transmission time transmitted from the GPS satellite 6 or the like. For this reason, in the portable terminal 4, the worker's position (referred to as worker position) and the detection time when the worker position is detected by holding the portable terminal 4 when the worker performs farm work. Can be obtained.

The mobile terminal 4 includes a communication device 41 that performs wireless communication. The communication device 41 performs, for example, wireless communication such as IEEE 802.11 series Wi-Fi (registered trademark), which is a communication standard, or wireless communication using a mobile communication network (for example, a mobile phone communication network).
For this reason, the mobile terminal 4 can acquire the farm work data by wireless communication with the data collection device 3 and detects the acquired farm work data, the worker position of the worker during the farm work, and the worker position. The detected time etc. can be transmitted to the outside by wireless communication of the mobile communication network. Note that the communication distance of the wireless communication between the portable terminal 4 and the data collection device 3 is a short distance, and is set to a range of 0 to 20 m, for example (the maximum value of the communication distance is 20 m).

It is desirable that the communication device 41 also transmits the mobile terminal 4, that is, worker specifying information (for example, a telephone number, a unique ID number, etc.) for specifying the worker who owns the mobile terminal 4 to the outside. In this way, it is possible to identify who is the worker who has the mobile terminal 4.
In summary, in such a work management system 1, work machine side information (agricultural work data, work machine specifying information, etc.) when farm work is performed is collected by the data collection device 3. Moreover, in the work management system 1, mobile side information (worker position, detection time, worker specific information) that has performed farm work can be acquired on the mobile terminal 4 side, and the work machine side information and mobile side information can be obtained. It can be transmitted from the portable terminal 4 to the outside.

Now, the work machine side information and the mobile side information transmitted from the mobile terminal 4 to the outside can be stored in the work management support apparatus 5 that manages farm work. The work management support apparatus 5 is configured by a server arranged on a network.
The server 5 organizes the farm work data transmitted from the portable terminal 4 as the work machine side information, thereby creating, for example, a daily work report after the end of the farm work, a work plan, an analysis of the farm work, a management plan, and the like. be able to. In particular, the server 5 can analyze the worker position after the end of the farm work.

Next, the flow of transmitting work implement side information and portable side information from the agricultural machine 2 (data collection device 3) to the server 5 via the portable terminal 4 will be described in detail by taking a tractor as an example.
As shown in FIG. 10, the tractor 2 is configured by mounting an engine 11, a transmission 12, and the like on a traveling vehicle (traveling vehicle body) 10 with wheels attached to the front and rear. An independently mounted cabin 13 is provided behind the engine 11, and a driver's seat 14 is provided in the cabin 13. In addition, a three-point link mechanism 15 is provided at the rear portion of the traveling vehicle 10 so as to be movable up and down, and a PTO shaft that transmits power from the engine 11 is provided. A working device 16 such as a fertilizer spraying device, a tilling device, a pesticide spraying device, a seeding spraying device, and a harvesting device is detachably attached to the three-point link mechanism 15. FIG. 10 shows an example in which the fertilizer application device is attached to the three-point link mechanism 15.

  As shown in FIG. 1, the tractor 2 is equipped with a control device 8 in addition to the data collection device 3. The control device 8 performs traveling system control, working system control, and the like of the tractor 2, and is provided around the driver's seat as the traveling system control, for controlling the operation of the engine or as the working system control. When an input from an operation tool such as an operation 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 8 are not limited to those described above.

  The data collection device 3 automatically collects various data related to farm work when the tractor 2 is operating via a vehicle network to which various sensors, the control device 8 and the like are connected. For example, when a cultivator is connected to the rear part of the tractor 2 as the working device 16 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 3 acquires the rotary speed, rotary load, engine speed, vehicle speed, tilling depth, and the like as farm work data.

  In addition, when the work device 16 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), etc., is a vehicle communication network. The data collection device 3 outputs the vehicle speed, the engine speed, the fertilizer application amount (fertilization amount), the agricultural chemical application amount, and the seeding application amount as farm work data. Alternatively, when the work device 16 is a harvesting device, data such as the vehicle speed, engine speed, and harvest amount are output on the vehicle communication network, and the data collection device 3 uses the farm speed data for the vehicle speed, engine speed, and harvest amount. Get as. In addition to this, when the farm work data is a combine, for example, the harvesting clutch is turned on or off, the rice transplanter is turned on or off, the planting clutch is turned on or off, and the tractor is output of the PTO shaft ( The number of rotations) is the height of the three-point link mechanism 15 ascending / descending. The farm work data may be an operation flag indicating whether the agricultural machine 2 is operating.

  The data collection device 3 also includes a first storage unit (buffer) 33 that temporarily stores various information. The first storage unit 33 stores farm work data and work machine specifying information. The farm work data is sequentially stored in the first storage unit 33 every time the tractor 2 moves or every time the tractor 2 operates. Further, the data collection device 3 is provided with a timer unit 34 that measures time. The time counted by the timing unit 34 when detecting the farm work data is stored in the first storage unit 33 as the data detection time. The time counted by the time measuring unit 34 may be an accumulated operation time (hour meter) obtained by accumulating the operation time when the tractor 2 is operated, or may be a time (year, month, day, hour, minute, second). Alternatively, it may be a counter value obtained by counting up the elapsed time.

As will be described later, when the communication device 31 of the data collection device 3 is authenticated with the portable terminal 4, the farm work data stored in the first storage unit 33 (rotary speed, rotary load, engine speed, The work machine side information such as the vehicle speed, the working depth, and the work machine specifying information is transmitted to the mobile terminal 4. Note that the communication device 31 also transmits the data detection time to the mobile terminal 4 as farm work data.

For example, before communication between the data collection device 3 and the portable terminal 4, authentication information (for example, an SSID, a network key, etc.) of the data collection device 3 to be connected is input (registered) in advance to the portable terminal 4. ) That is, authentication information of the data collection device 3 to be connected is stored in advance in the second storage unit 43 of the mobile terminal 4.
Then, in a situation where a beacon including authentication information is transmitted from the data collection device 3, the mobile terminal 4 enters the communication area of the data collection device 3 to be connected, and the mobile terminal 4 is connected to the data collection device 3. When the beacon transmitted from is received, the communication device 41 of the mobile terminal 4 transmits the authentication information to the data collection device 3. When receiving the authentication information transmitted from the mobile terminal 4, the data collection device 3 authenticates with the mobile terminal 4 using the authentication information stored in the data collection device 3. When the authentication is established and the connection between the data collection device 3 and the portable terminal 4 is established, the communication device 31 of the data collection device 3 transmits work implement side information to the portable terminal 4. When the mobile terminal 4 receives the work side information, the mobile terminal 4 stores the received work machine side information in the second storage unit 43.

In addition, the position detection device 40 of the mobile terminal 4 sequentially detects its own position when the position detection function of the mobile terminal is turned on. This self-position is sequentially stored together with the detection time (the time when the self-position is detected) in the second storage unit 43 provided in the mobile terminal 4.
As described above, by performing communication between the data collection device 3 and the portable terminal 4 or detecting the self-position, the work storage side information (agricultural work) transmitted from the data collection device 3 is stored in the second storage unit 43. Data, work machine identification information, etc.) are stored, and mobile side information (self-location, worker identification information, etc.) is stored.

  When the mobile terminal 4 accesses the server 5 and the server 5 permits access from the mobile terminal 4 (authentication between the mobile terminal 4 and the server 5 is established), the communication device 41 of the mobile terminal 4 The work machine side information stored in the second storage unit 43 is transmitted to the server 5, and the portable side information is transmitted to the server 5. Among the mobile-side information transmitted from the mobile terminal 4 to the server 5, the self-position of the mobile terminal 4 is transmitted to the server 5 as the worker position.

  On the other hand, the server 5 that is a work management support apparatus includes an information acquisition unit 51 that receives various data (information) from the outside. The information acquisition unit 51 receives (acquires) work machine side information (agricultural work data, work machine specifying information) and mobile side information (worker position, detection time, worker specifying information) transmitted from the mobile terminal 4. . The information acquisition unit 51 only needs to acquire at least the worker position and the detection time.

  The server 5 includes a third storage unit 52 that stores work implement side information, portable side information, work place information related to the work place (farm field), and the like. The 3rd memory | storage part 52 memorize | stores work implement specific information and farm work data (engine rotation speed, fertilizer application amount, data detection time etc.) as work implement side information, for example, as shown to Fig.2 (a). Moreover, the 3rd memory | storage part 52 memorize | stores worker specific information, worker position (latitude, longitude), and detection time as mobile side information, for example, as shown in FIG.2 (b). In addition, the 3rd memory | storage part 52 memorize | stores the map (work place map) containing a work place (farm field) as work place information. The workplace map has a position (latitude and longitude) for indicating the location of the workplace, in addition to an image and a diagram showing the workplace (farm field).

Now, the work management support apparatus (server 5) of the present invention can look back and confirm the past worker position and the like when the worker performs the farm work.
Hereinafter, the work management support apparatus (server 5) will be described in detail.
As shown in FIG. 1, the server 5 includes an arithmetic processing unit 53 and a display unit 54.
The arithmetic processing unit 53 is configured by a CPU or the like, and performs various arithmetic processes in the server 5. The display unit 54 includes a liquid crystal, a touch panel, and the like, and is input via various information (worker side information, portable side information, work place map), an interface, and the like stored in the third storage unit 52. Etc. are displayed.

The arithmetic processing unit 53 and the display unit 54 will be described in detail.
The arithmetic processing unit 53 performs processing in the third storage unit 52 and the display unit 54 and includes a time input unit 55. The time input unit 55 sets the time input by the input interface connected to the server 5 as the designated time.
For example, when a time “10:30” is input (designated) by an input interface such as a keyboard and a mouse connected to the server 5, the time input unit 55 designates “10:30” as a designated time. Hold as. Alternatively, when a time of “6:00 to 9:00” is input through the input interface, the time input unit 55 sets “6:00” as the first designated time and sets “9:00” "Is designated as the second designated time. As described above, when there are two or more designated times, the time input unit 55 holds all times that fall within the time zone (designated time zone) from the first designated time to the second designated time as designated times. In the above-described example, since the first designated time is “6:00” and the second designated time is “9:00”, all the times from “6:00 to 9:00” Becomes the specified time. Note that the input interface may be a touch panel or other one.

When the designated time is input by the time input unit 55, the arithmetic processing unit 53 obtains the worker position corresponding to the designated time based on the designated time and the detection time stored in the third storage unit 52. .
Specifically, when the designated time is designated, the arithmetic processing unit 53 extracts the detection time that matches the designated time from the mobile-side information in the third storage unit 52. For example, when a designated time (designated time zone) from 6:00 to 9:00 is designated, the arithmetic processing unit 53 is stored in the third storage unit 52 as shown in FIG. Among the detected times (5:05 to 20:15), detection times from “6:00 to 9:00” that match the specified time are extracted.

Next, the arithmetic processing unit 53 stores the worker positions (for example, latitude 34.558765, longitude 135.469700 to latitude 34.558700, longitude 135.469700) corresponding to each detection time from 6:00 to 9:00 in the third storage. Read from unit 53. That is, the arithmetic processing unit 53 obtains the worker position corresponding to the designated time.
The display unit 54 includes a position display unit 56 that displays the worker position corresponding to the designated time obtained by the arithmetic processing unit 53. The position display unit 56 is configured by a rectangular display frame or the like, and displays at least the worker position on the display frame. Hereinafter, a screen that displays the position display unit 56 (display frame) is referred to as a “review screen”.

  For example, as described above, the operator position latitude 34.558765, longitude 135.469700 to latitude 34.558700, longitude 135.469700 corresponding to the specified time (detection time) from 6:00 to 9:00 is obtained by the arithmetic processing unit 53. In this case, as shown in FIG. 3A, on the reflection screen S, the position display unit 56 displays the worker position Q from 6:00 to 9:00, which is the designated time. The display of the worker position Q on the position display unit 56 may indicate each worker position as a plot point, or may display it as a trajectory (worker trajectory) connecting the worker positions continuously. .

  When the position display unit 56 displays the worker position Q at the specified time on the reflection screen S, as shown in FIG. 3B, the worker position Q on the work place map M including the farm field (work place). It is desirable to display. The arithmetic processing unit 53, for example, sets a place (overlapping place) that overlaps the worker position (latitude 34.558765, longitude 135.469700 to latitude 34.558700, longitude 135.469700) up to a specified time (6:00 to 9:00) as the workplace map M. From the data (latitude, longitude). The position display unit 56 displays the overlapping place N extracted by the arithmetic processing unit 53 and displays the worker position Q at the specified time on the overlapping place N.

When the worker position Q and the work place map M at the specified time are displayed on the position display unit 56, other work different from the worker position at the specified time (one worker position, that is, the first worker position). The worker position (second worker position) may also be displayed.
When displaying the first worker position Q1 and the second worker position Q2, first, the arithmetic processing unit 53 not only extracts the first worker position Q1 at the specified time but also stores it in the third storage unit 52. The stored second worker position Q2 is also extracted from the third storage unit 52. Then, as shown in FIG. 4, the display unit 54 displays the workplace map M and also displays both the first worker position Q1 indicated by a solid line and the second worker position Q2 indicated by a dotted line. The display unit 54 changes the color indicating the first worker position Q1 and the color indicating the second worker position Q2 so that the first worker position Q1 and the second worker position Q2 can be identified. May be.

As described above, according to the present invention, the work position of the worker after the farm work can be stored in the work management support device (server) 5 and the position of the worker can be cut out (extracted) at the specified time. You can look back on how the worker was moving at the specified time after farming.
Further, when displaying the worker position at the designated time, the worker position Q and the work place map M are displayed on the display unit 54 so as to overlap with each other. You can see if you were there. Further, since the worker position other than the designated time is also displayed on the display unit 54 so as to be distinguished from the worker position at the designated time, the movement of the worker other than the designated time and the movement at the designated time are also shown. Can be grasped while contrasting.

As described above, after the farm work, the worker can confirm his / her position at the time of the farm work. For example, it is easy to create a daily work report for reporting the farm work. In addition, an administrator who manages a plurality of workers can grasp and analyze the movements of the plurality of workers during farm work, which can be used for future work plans and farm management.
[Second Embodiment]
In the second embodiment, in addition to displaying the worker position and the workplace map M on the display unit 54 of the server 5 which is a work management support device, the location (intersection location) where the boundary of the workplace intersects with the worker position. The intersection time is displayed. Differences from the first embodiment will be described.

As shown in FIG. 5, the arithmetic processing unit 53 includes a determination unit 57 and an intersection time calculation unit 58. The determination unit 57 and the intersection time calculation unit 58 are configured by a program or the like.
The determination unit 57 determines whether or not the worker position at the specified time is straddling the work place of the work place map M.
Specifically, as shown in FIG. 6A, the determination unit 57 uses the locus line Q3 indicating the worker locus obtained by connecting the work positions within the designated time, and the appearance of the work place in the work place map M. Based on the boundary line F indicating (boundary), it is determined whether or not the work position extends over the work place map M. When the locus line Q3 of the work locus intersects with the boundary line F of the work place, the determination unit 57 determines that the worker position straddles the work place of the work place map M. On the other hand, as shown in FIG. 6B, when the locus line Q3 of the worker trajectory and the boundary line F of the workplace do not intersect, it is determined that the worker position does not straddle the workplace of the workplace map M. To do.

When the determination unit 57 determines that the worker position crosses the workplace, the intersection time calculation unit 58 obtains a time (intersection time) at which the worker position and the workplace intersect. For example, as shown in FIG. 6C, when the worker position P1 and the outline F of the workplace match each other, the intersection time calculation unit 58 sets the detection time corresponding to the worker position P1 to the intersection time. And
Further, as shown in FIG. 6 (d), the worker position P2 and the worker position P3 are located at both ends of the contour line F of the workplace, and the worker trajectory connecting the worker position P2 and the worker position P3 is shown. When intersecting with the contour line F, for example, the intersection time calculation unit 58 sets an intermediate time between the detection time T2 and the detection time T3 as the intersection time.

The display unit 54 displays the intersection time obtained by the intersection time calculation unit 58 in the vicinity of the intersection where the worker position and the outline F of the workplace intersect, as shown in FIG. 6A, for example.
In this way, in addition to displaying the worker position and the workplace map M, if the intersection time at which the boundary of the workplace (farm field) intersects with the worker position is displayed, the time when the worker entered and exited the farm field can be determined as the intersection time. Can be grasped from.
[Third Embodiment]
In the third embodiment, the worker position can be extracted at a specified time while viewing the worker position displayed on the position display unit 56 of the server 5 which is a work management support apparatus. Differences from the first embodiment and the second embodiment will be described.

As shown in FIG. 7, the display unit 54 includes a time passage display unit 60 and a worker display unit 61 in addition to the position display unit 56 that displays the worker position Q and the work place map M.
The time lapse display unit 60 is for easily recognizing the flow of time (time lapse) displayed on the display unit 54 (return screen S), and is displayed around the position display unit (display frame) 56. ing.

  Specifically, a time passage display unit 60 is provided below the position display unit 56. The time-lapse display unit 60 includes a scale line 60a arranged at a predetermined interval in the left-right direction along the lower end of the display frame 56, and a time display body 60b that indicates the time by a numeral or the like on the scale line 60a. Has been. The time passage display unit 60 is provided along the scale line 60a with the time axis 60c on the straight line indicating the flow of time being below the scale line 60a.

If the change part 62 is selected using an input interface, the time of the time display body 60b can be increased / decreased.
The worker display unit 61 displays various information related to the worker. The worker display unit 61 is provided on the lower side of the time progress display unit 60. The worker name display unit 65 for displaying the worker name and information (work related information) on the worker's work etc. An operator time display unit 66 for displaying with progress is provided. The worker name display unit 65 is provided below the time passage display unit 60 (display frame 56) and on the left side of the time axis 60c, and the worker time display unit 66 is provided with the time passage display unit 60 (display frame). 56).

  The worker name display unit 65 displays the worker name. For example, when the worker name displayed on the reflection screen S is registered in the server 5 in advance, the worker name display unit 65 displays the worker name registered in the server 5. Alternatively, when the worker identification information and the worker name are associated in advance and stored in the third storage unit 52 of the server 5, the worker name display unit 65 displays the worker name corresponding to the worker identification information. Is displayed. Note that the method of displaying the worker name by the worker name display unit 65 is not limited to that described above.

The worker time display unit 66 displays work related information corresponding to the worker (display worker) displayed on the worker name display unit 65. The worker time display unit 66 displays a detection time zone obtained at the detection time when the worker position is detected as one piece of work related information.
Specifically, when displaying the detection time on the worker time display unit 66, first, the arithmetic processing unit 53 determines whether or not the worker position and the detection time of the display worker are stored in the third storage unit 52. Judging. Here, when the worker position and the detection time of the display worker are stored in the third storage unit 52, the arithmetic processing unit 53 extracts the detection time of the display worker from the third storage unit 52 and detects it. The detection time zone in which the worker position is detected is obtained using the time.

Specifically, assuming that the worker position and the detection time of the worker A are stored in the third storage unit 52 as shown in FIG. 2, the arithmetic processing unit 53 detects the position by the position detection device 40. The section in which the worker position is detected is extracted at a sampling interval (for example, every second).
For example, since the worker position of “latitude 34.558765, longitude 135.469700 to latitude 34.558700, longitude 135.469700” is detected at a constant interval (every second), the arithmetic processing unit may detect the work position (latitude 34.558765, longitude 135.469700). ~ Latitude 34.558700, Longitude 135.469700). Then, in the extracted section, the arithmetic processing unit 53 detects the detection time corresponding to the first worker position (start detection time 06:00) and the detection time corresponding to the last worker position (end detection time 09 hours). 00 minutes). The arithmetic processing unit 53 sets a time zone (from 06:00 to 09:00) between the start detection time and the end detection time as the detection time zone.

When the extraction of the detection time zone (06:00 to 09:00) by the arithmetic processing unit 53 is completed, the worker time display unit 66 displays the time indicated by the detection time zone on the time elapsed display unit 60. If it is set (when the time indicated by the scale line 60a or the time display body 60b overlaps the time of the detection time zone), the detection time zone is displayed by the linear display bar 69.
Specifically, the worker display unit 65 positions the tip of the display bar 69 indicating the beginning of the detection time zone immediately below the position indicating the same time as “06:00” of the start detection time on the time axis 60c. indicate. In addition, the worker display unit 65 displays the rear end of the display bar 69 indicating the end of the detection time zone, immediately below the position indicating the same time as the end detection time “09:00” on the time axis 60c. .

The position display unit 56 displays the worker position Q of the display worker displayed on the worker name display unit 65. When one worker name is displayed on the worker name display unit 65, The worker position Q of the worker corresponding to the worker name is displayed. When a plurality of worker names are displayed on the worker name display unit 65, the position display unit 56 displays the worker position Q of the worker specified by the input interface or the like.

Thus, by displaying the worker name, the displayed worker position of the displayed worker, and the detected time zone in which the worker position is detected on the display unit 54, the time zone in which the worker has moved, and the worker location Can be grasped simultaneously on one screen.
[Fourth Embodiment]
