A work management system including a work management support apparatus and a work management support apparatus according to an embodiment of the present invention will be described below with reference to the drawings. 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 is, for example, a worker who has performed farm work in a field (work field) for cultivating crops or the like, or an agricultural machine (
Various management of the work machine). 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 work such as an agricultural machine, and is, for example, a manufacturing number, a model, a model number, or the like. If 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).

The communication device 41 desirably transmits the mobile terminal 4, that is, worker identification information (for example, a telephone number, a unique ID number, etc.) for identifying the worker who owns the mobile terminal 4. In this way, it is possible to identify who is the worker who has the mobile terminal 4.
In summary, in the work management system 1, work machine side information (farm work data, work machine specifying information, etc.) when farm work is performed can be collected by the data collection device 3. Moreover, in the work management system 1, portable side information (worker position, detection time, worker identification information) that has performed farm work can be acquired on the portable terminal 4 side, and these work machine side information and portable side information are 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. 19, 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. 19 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 workplace map which shows the map of a workplace (farm field) as workplace 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, in the work management support apparatus (server 5) of the present invention, it is possible to look back and confirm the past worker position and the like when the worker performs 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 monitor (liquid crystal) or the like, and the third storage unit 52.
Various information (work machine side information, mobile side information, work place map) stored in the computer, information input via an interface, and the like can be displayed.

FIG. 3 shows an example of the display unit 54.
As shown in FIG. 3, the display unit 54 includes a position display unit 56, an operator name display unit 65, and a specified time input unit 78.
The position display unit 56 is configured by a rectangular display frame or the like, and displays 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”.

  The worker name display unit 65 displays the worker name on the reflection screen S. For example, when the worker name to be displayed on the reflection screen 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 designated time input unit 78 is for inputting the designated time on the retrospective screen S, displays the input frame 78a for inputting the designated time, and designates the designated time when the designated time is input to the input frame 78a. Is displayed. “Year, month, day, hour, minute” may be input to the input frame 78a. Alternatively, the input frame 78a and the calendar 78b are displayed on the reflection screen S, and “year” is displayed on the calendar 78b. , Month, day "can be designated, and" hour, minute "can be entered in the input frame 78a. The designated time input unit 78 is not limited to the one described above.

  The position display unit 56 displays the worker position of the worker corresponding to the worker name displayed on the worker name display unit 65 on the reflection screen S. For example, when one worker name (worker A) is displayed on the worker name display unit 65, the worker position of the worker A is displayed. When a plurality of worker names are displayed on the worker name display unit 65, the worker position of the selected worker is displayed. The worker is selected by clicking the worker name displayed on the worker name display unit 65 using the input interface. Note that the selection of the worker is not limited to the method described above.

Next, the arithmetic processing unit 53 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 holds the time input to the specified time input unit 78 on the retrospective screen S as the specified time. For example, when a time “10:30” is input (designated) to the designated time input unit 78 (input frame 78a) by operating an input interface such as a keyboard and a mouse connected to the server 5, the time is input. The unit 55 holds “10:30” as the designated time. Alternatively, when a time “6:00 to 9:00” is input to the designated time input unit 78 (input frame 78a) by operating the input interface, the time input unit 55 sets 6:00. The first designated time is the time, and 9:00 is 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.

As described above, when the designated time is input by the time input unit 55, the arithmetic processing unit 53 performs work corresponding to the designated time based on the designated time and the detection time stored in the third storage unit 52. The person's position is determined. 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.
Here, as shown in FIG. 3, in the reflection screen S, “6:00 to 9:00” is input to the designated time input unit 78 (input frame 78a), and the position display unit 56 displays the worker. Assume that the worker position of A is displayed, and the processing of the arithmetic processing unit 53 will be described.

When the designated time (designated time zone) from 6:00 to 9:00 is designated, the arithmetic processing unit 53 is first stored in the third storage unit 52 as shown in FIG. Among the detection times (from 5:05 to 20:15) of the worker A, the detection times from “6:00 to 9:00” that match the specified time are extracted.
Next, the arithmetic processing unit 53 includes the worker position of the worker A corresponding to each detection time from 6:00 to 9:00 (for example, latitude 34.558765, longitude 135.469700 to latitude 34.558700, longitude 135.469700). Is read from the third storage unit 53.

  As described above, when the operator position of the worker A at the specified time (specified time zone) from 6:00 to 9:00 is obtained by the arithmetic processing unit 53, the position display unit 56 displays the field ( The worker position (latitude 34.558765, longitude 135.469700 to latitude 34.558700, longitude 135.469700) Q corresponding to the designated time is displayed on the workplace map M including the workplace. That is, the position display unit 56 reads the workplace map M from the third storage unit 52 and displays the worker position of the worker A obtained by the arithmetic processing unit 53. In addition, 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) that connects each worker position continuously. Also good.

  Now, the work place map M (data indicating the work place map M) has work place information regarding each work place (a farm field). The work place map M has the position (latitude, longitude, or address) of each field as work place information so that each field can be distinguished. And each field displayed on the screen of the reflection screen S, that is, the display unit 54 (position display unit 56) can be selected.

  Specifically, the arithmetic processing unit 53 includes a work place selection unit 59 that selects a work place such as a farm field displayed on the work place map M. On the reflection screen S, a pointer 85 that can be moved up and down, left and right is displayed on the reflection screen S. After the pointer 85 is overlaid on the work place map M displayed on the position display unit 56, a mouse is displayed. When the determination button (enter) of the input interface such as is pressed, the workplace selection unit 59 selects the field that overlaps the pointer 85.

  As shown in FIG. 3, the pointer 85 is placed on the field A that overlaps the worker position (latitude 34.558765, longitude 135.469700 to latitude 34.558700, longitude 135.469700) at the specified time (6:00 to 9:00) and the enter button is pressed. When pressed, the workplace selection unit 59 is assumed to select the field A. The movement and selection of the pointer 85 are determined using an input interface such as a mouse. Further, when the display unit 54 is configured by a touch panel that also has an input interface, it is assumed that the selection by the pointer 85 is performed by an operation of tapping (touching) the work place map M displayed on the position display unit 56 with a finger. It is desirable.

  The arithmetic processing unit 53 associates the selected field with the worker position at the specified time, and causes the third storage unit 52 to store the associated field and the worker position at the specified time. As described above, when the field A is selected in the state where the worker position at the designated time from 6:00 to 9:00 is displayed on the position display unit 56, as shown in FIG. The processing unit 53 associates the worker position (latitude 34.558765, longitude 135.469700 to latitude 34.558700, longitude 135.469700) with the workplace information (latitude, longitude, address, etc.) of the farm A, and stores these information in the third storage unit 52. As work records. When the arithmetic processing unit 53 associates the worker position at the designated time with the work place (farm field) of the work place map M and stores it as a work record, the operator name corresponding to the worker position and the designated time or designated time zone Is preferably stored as a work record. The work record is displayed on the display unit 54 by accessing the third storage unit 52, printed, or displayed on the portable terminal 4 by transmitting to the portable terminal 4. Is possible.

  According to this, the operator position at the designated time is displayed by the arithmetic processing unit 53 and the display unit 56, and the work place map M is displayed. The worker position at the designated time and the work place (farm field) of the selected work place map M are displayed. ). After the association, the worker position and the field at the specified time can be saved as a work record, and the work record can be easily created.

Therefore, for example, after the end of one day of farm work, the worker performs associating as necessary while confirming the positional relationship between the worker position at the specified time displayed on the reflection screen S and the workplace map M. As a result, work records as shown in FIGS. 4 and 5 can be easily created. [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. 6, 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. 7A, the determination unit 57 includes a trajectory line Q3 indicating a worker trajectory obtained by connecting each work position within a specified time, and an 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. 7B, 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. 7C, when the worker position P1 and the contour line 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. 7 (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. 7A, for example. Further, when the arithmetic processing unit 53 associates the worker position at the designated time with the work place (farm field) of the work place map M and saves it as a work record, the operation time is also associated with the worker position and the work place at the designated time. Save as a record.

Thus, in addition to displaying the worker position and the workplace map M, the intersection time at which the boundary of the workplace (farm field) intersects with the worker position is stored in association with the worker position and the workplace at the specified time. By doing so, it is possible to grasp and record the time (intersection time) when the operator enters and exits the field.
[Third Embodiment]
In the third embodiment, instead of the above-described designated time input unit 78 (input frame 78a), as shown in FIG. 8, a designated display tool 63 for designating a designated time is displayed on the display unit 54, and the designated display tool is displayed. The designated time designated at 63 is designated as the designated time by the time input unit 55. Differences from the first embodiment and the second embodiment will be described.

The display unit 56 includes a time passage display unit 60 and a designation display tool 63. The time lapse display unit 60 is for making it easy to recognize the flow of time (time lapse) when the designated time is designated by the designated display tool 63 and is displayed around the position display unit (display frame) 56. Has been.
Specifically, the 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.

The designation display tool 63 can be moved by an operation (instruction) of an input interface such as a mouse, a keyboard, or a touch panel. The designation display tool 63 has a designation section 64 that pinpoints the designated time. The designation display tool 63 on the time passage display section 60 (time axis 60c) corresponding to the stop position of the designation display tool 63 (designation section 64) is shown. The time is the time (specified time) indicated by the specified display tool 63 (designating unit 64). That is, the time input unit 55 sets the time corresponding to the time lapse unit 60 pointed to by the position of the designation display tool 63 as the designated time.

  More specifically, two designation display tools 63 are displayed on the display unit 54, and the designation display tool 63a (the first display unit 61) disposed on the left side of the display unit 54 (the past viewed from the passage of time on the time axis 60c). The designation tool) designates the first designated time. A designated display tool 63b (referred to as a second designated tool) arranged on the right side of the display unit 54 (the future as viewed from the passage of time on the time axis 60c) designates a second designated time. For example, when “6:00” is specified by the first specifying tool 63a and “9:00” is specified by the second specifying tool 63b, the time input unit 55 sets the first specified time to 6:00. Minutes, the second designated time is 9:00, and all the times from the first designated time to the second designated time and the designated time zone are designated (designated time).

The position display unit 56 displays the worker position in the specified time zone (between the first specified time and the second specified time). Further, when the first designated time or the second designated time is changed by the first designated tool 63a or the second designated tool 63b, the position display unit 56 displays the designated time from the first designated time after the change to the second designated time. The operator position of the belt is displayed.

A work record can be created by associating the workplace with the workplace.
[Fourth Embodiment]
In the fourth embodiment, work-related information is displayed on the display unit 56 in addition to the worker name, and a designated time can be designated while referring to this information. Differences from the above-described embodiment will be described.

As shown in FIG. 9, the display unit 56 includes an operator name display unit 65, an operator time display unit 66, and a designation display tool 63 in addition to the position display unit 56. Since the position display unit 56 is the same as that in the above-described embodiment, the description thereof is omitted.
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 designation display tool 63 is provided with a designation unit 64 that indicates a designated time in a pinpoint manner. The designation unit 64 is extended to the worker time display unit 66.

  The worker time display unit 66 displays work related information in a detection time zone obtained at a detection time when the worker position is detected. 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, when the worker position and the detection time of the worker A are stored in the third storage unit 52 as illustrated in FIG. 3, the arithmetic processing unit 53 uses the position detection device 40 to detect the position. A section in which the worker position is detected at intervals (for example, every second) is extracted.
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. .

  According to this, when the worker looks at the detection time zone display bar 69 displayed on the worker time display unit 66, the time zone in which the worker has moved (the time zone in which the worker position is detected) is displayed. It is possible to immediately grasp, and simultaneously designate the detection time zone and the worker position Q displayed on the position display unit 56, and designate the designated time by the movement of the first designated tool 63a and the second designated tool 63b. It is possible to confirm the worker position in a predetermined time zone.

Note that the position display unit 56 may display both the worker position of the entire time zone displayed by the display bar 69 and the worker position of the designated time zone. For example, as shown in FIG. 9, the worker A displays the worker position Q in the entire time zone (6:00 to 9:00) displayed on the display bar 69. In FIG. 9, a line connecting Y1 to Y2 indicates the worker position Q in all time zones. In this state, when a designated time zone (7:00 to 9:00) is designated, among the worker positions Q in all time zones, the worker positions in the designated time zone are indicated by solid lines and the remaining work The person's position is indicated by a dotted line. In this way, it is possible to grasp the relationship between the worker position in the entire time zone and the worker position in the designated time zone.

Specifically, when displaying the work designation time on the worker time display unit 66, first, the arithmetic processing unit 53 determines whether or not the work designation time of the display worker is stored in the third storage unit 52. To do. Here, when the work designation time of the display worker is stored in the third storage unit 52, the arithmetic processing unit 53 extracts the work designation time of the display worker from the third storage unit 52 and specifies the work designation. A work designated time zone for indicating the time in a time zone is obtained. For example, the arithmetic processing unit 53 sets the work end designated time from the work start designated time stored in the third storage unit 52 as the work designated time zone.

  The worker time display unit 66 displays the work designated time zone obtained by the arithmetic processing unit 53 on the time elapsed display unit 60 (the time indicated by the scale line 60a or the time display body 60b is the work designated time. If it overlaps with the time of the belt), the work designated time zone is displayed by the linear display bar 69. Specifically, the worker display unit 65 displays a display bar 69 indicating the beginning of the work designation time zone immediately below the position indicating the same time as “05:00” of the work start designation time on the time axis 60c. Display the tip. In addition, the worker display unit 65 displays a rear end of the display bar 69 indicating the end of the work designated time zone immediately below the position indicating the same time as “12:30” of the work designated time zone on the time axis 60c. indicate.

According to this, when the worker looks at the display bar 69 of the work designated time zone displayed on the worker time display section 66, the time zone (work start designated time, work end designated The time)) can be immediately grasped, and the first designated tool 63a and the second designated tool 63b are moved while simultaneously viewing the work designated time zone and the worker position Q displayed on the position display unit 56. A specified time can be specified.

FIG. 13 shows an example of the display unit 54.
As shown in FIG. 13, the display unit 54 includes a position display unit 56, a work machine name display unit 81, and a specified time input unit 78.
The work machine name display unit 81 displays the work machine name on the reflection screen S. When the work machine name to be displayed is registered in the server 5 or the like in advance, the work machine name display unit 81 reads the registered work machine name from the server 5 and displays it. When a plurality of work machine names are registered in the server 5, the respective work machine names are displayed in order from the top. Alternatively, when the work machine specifying information and the work machine name are associated in advance and stored in the third storage unit 52 of the server 5, the work machine name display unit 81 displays the work machine name corresponding to the work machine specifying information. Is displayed. In addition, the method by which the work machine name display unit 81 displays the work machine name is not limited to that described above.

The position display unit 56 displays the work machine position of the work machine corresponding to the work machine name displayed on the work machine name display unit 81 on the reflection screen S. For example, when one work machine name (work machine A) is displayed on the work machine display unit 81, the work machine position of the work machine A is displayed. Also,
When a plurality of work machine names are displayed in the work machine name display unit 81, the work machine position of the selected work machine is displayed. The work implement is selected by clicking the work implement name displayed on the work implement name display unit 81 using the input interface. The selection of the work machine is not limited to the method described above.

Next, the arithmetic processing unit 53 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. Since the time input unit 55 is the same as that of the above-described embodiment, the description thereof is omitted. Here, when the designated time is input by the time input unit 55, the arithmetic processing unit 53 causes the work machine corresponding to the designated time based on the designated time and the detection time stored in the third storage unit 52. Find the position. 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, as shown in FIG. 13, when “6:00 to 9:00” is input to the input frame 78a on the reflection screen S and the work machine A is selected, the arithmetic processing unit 53 specifies Detection times from “6:00 to 9:00” that coincide with the time are extracted. Then, the arithmetic processing unit 53 reads the work machine position R of the work machine A corresponding to each detection time from 6:00 to 9:00 from the third storage unit 53. When the reading of the work machine position R of the work machine A is completed, the position display unit 56 displays the work machine position R corresponding to the designated time on the work place map M including the agricultural field (work place). That is, the position display unit 56 reads the work place map M from the third storage unit 52 and displays the work machine position of the work machine A obtained by the arithmetic processing unit 53. In addition, the display of the work machine position R on the position display unit 56 may indicate each work machine position as a plot point, or may display the work machine position as a trajectory (work machine trajectory) continuously connecting the work machine positions. Also good.

  Now, the work place map M (data indicating the work place map M) has work place information regarding each work place (a farm field). The work place map M has the position (latitude, longitude, or address) of each field as work place information so that each field can be distinguished. And each field displayed on the screen of the reflection screen S, that is, the display unit 54 (position display unit 56) can be selected.

  Specifically, the arithmetic processing unit 53 includes a work place selection unit 59 that selects a work place such as a farm field displayed on the work place map M. On the reflection screen S, a pointer 85 that can be moved up and down, left and right is displayed on the reflection screen S. After the pointer 85 is overlaid on the work place map M displayed on the position display unit 56, a mouse is displayed. When the determination button (enter) of the input interface such as is pressed, the workplace selection unit 59 selects the field that overlaps the pointer 85.

  Then, when the pointer 85 is placed on the farm field A that overlaps the work machine position R and the determination button is pressed, the work field selector 59 assumes that the farm field A has been selected. The movement and selection of the pointer 85 are determined using an input interface such as a mouse. Further, when the display unit 54 is configured by a touch panel that also has an input interface, it is assumed that the selection by the pointer 85 is performed by an operation of tapping (touching) the work place map M displayed on the position display unit 56 with a finger. It is desirable.

  The arithmetic processing unit 53 associates the selected farm field with the work machine position at the specified time, and causes the third storage unit 52 to store the associated farm field and the work machine position at the specified time. As described above, when the field A is selected in the state where the work machine position at the designated time from 6:00 to 9:00 is displayed on the position display unit 56, as shown in FIG. The processing unit 53 associates the work machine position (latitude 34.558765, longitude 135.469700 to latitude 34.558700, longitude 135.469700) with the work place information (latitude, longitude, address, etc.) of the farm A, and stores these information in the third storage unit 52. As work records. As shown in FIG. 14, the arithmetic processing unit 53 associates the work machine position at the specified time with the work place (farm field) of the work place map M and stores it as a work record, and the work machine name corresponding to the work machine position. It is desirable to store the designated time or the designated time zone as a work record. The work record is displayed on the display unit 54 by accessing the third storage unit 52, printed, or displayed on the portable terminal 4 by transmitting to the portable terminal 4. Is possible.

  According to this, the operation unit 53 and the display unit 56 display the work machine position at the designated time and also display the work place map M, and the work place at the designated time and the work place (farm field) of the selected work place map M. ). After the association, the work machine position and the field at the specified time can be saved as a work record, and the work record can be easily created.

Therefore, for example, after the end of a day of farm work, the worker performs associating as necessary while checking the positional relationship between the work machine position at the specified time displayed on the reflection screen S and the work place map M. Can do.
[Eighth Embodiment]
In the eighth embodiment, in addition to displaying the work machine position and the work place map M on the display unit 54 of the server 5 which is a work management support apparatus, a place (intersection place) where the work place boundary and the work machine position cross each other is displayed. The intersection time is displayed. Differences from the seventh embodiment will be described.

As illustrated in FIG. 15, 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 work machine position at the specified time is straddling the work place of the work place map M.
Specifically, as shown in FIG. 16A, the determination unit 57 uses the trajectory line R3 indicating the work implement trajectory 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 machine position extends over the work place map M. When the locus line R3 of the work locus and the boundary line F of the work place intersect, the determination unit 57 determines that the work machine position straddles the work place of the work place map M. On the other hand, as shown in FIG. 16B, when the trajectory line R3 of the work implement trajectory and the boundary line F of the work place do not intersect, it is determined that the work implement position does not straddle the work place of the work place map M. To do.

When the determination unit 57 determines that the work machine position straddles the work place, the intersection time calculation unit 58 obtains a time (intersection time) at which the work machine position and the work place cross each other. For example, as shown in FIG. 16C, when the work implement position P1 and the contour line F of the work place coincide with each other, the intersection time calculation unit 58 sets the detection time corresponding to the work implement position P1 to the intersection time. And
Further, as shown in FIG. 16 (d), the work implement position P2 and the work implement position P3 are located at both ends of the contour line F of the work place, and the work implement trajectory connecting the work implement position P2 and the work implement 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.

  For example, as shown in FIG. 16A, the display unit 54 displays the intersection time obtained by the intersection time calculation unit 58 in the vicinity of the intersection where the work machine position and the outline F of the workplace intersect. Further, when the operation processing unit 53 associates the work machine position at the designated time with the work place (farm field) of the work place map M and saves it as a work record, the arithmetic processing unit 53 associates the crossing time with the work machine position and the work place at the designated time. Save as a record.

Thus, in addition to displaying the work machine position and the work place map M, the intersection time at which the boundary of the work place (farm field) and the work machine position intersect is stored in association with the work machine position and the work place at the specified time. By doing so, it is possible to grasp and record the time (intersection time) when the operator enters and exits the field.
FIGS. 17 and 18 show a modification in the case where the work machine position is associated with the agricultural field. A modification will be described.

As shown in FIG. 17, instead of the designated time input unit 78 (input frame 78a), a designated display tool 63 for designating a designated time is displayed on the display unit 54, and the designated time designated by the designated display tool 63 is displayed as a time. It is good also as the designated time by the input part 55. FIG. The configurations of the time passage display unit 60 and the designation display tool 63 are the same as those in the third embodiment. Further, the present embodiment is the same as the third embodiment in which the worker is displayed except that the work machine position is displayed on the position display unit 63 and the work machine name display unit 81 displays the work machine name. That is, “worker” in the third embodiment may be read as “work machine”. As shown in FIG. 17, if the designation display unit 63 is displayed so that the designation time can be designated, the designation display tool 63 is appropriately moved to check the change of the work machine position due to the time.

  Further, as shown in FIG. 18, the designation display tool 63 may be moved while looking at the detection time zone in which the work implement position is detected. The time passage display unit 60 and the designation display tool 63 shown in FIG. 18 are also the same as those in the third embodiment and the fourth embodiment. Further, in FIG. 18, except that the work machine position is displayed on the position display unit 63 and the work machine name is displayed by the work machine name display unit 81, the same as in the fourth embodiment in which the worker is displayed. It is. That is, “worker” in the fourth embodiment may be read as “work machine”. As shown in FIG. 18, if the designated display tool 63 can be moved after displaying the detection time zone in which the work implement position is detected, the detection time zone of the work implement position can be immediately grasped, and a predetermined time It is easy to extract the position of the work machine.

In the above-described embodiment, the work management support apparatus 5 is configured by the server when associating the work machine position and the farm field. However, even when the work machine position and the farm field are associated, the work management support apparatus is used by the operator. You may comprise with the portable terminal which possesses, or may comprise with the installation type computer installed in the worker's house etc.
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. In the embodiment described above, a tractor has been described as an example of an agricultural machine, but a combine may be used. The combine is equipped with a sensor that detects the protein of the harvested cereal and a measuring instrument that detects the yield. When applied to the combine, the harvest, protein, etc. can be acquired as farm work data. It becomes possible to organize the yield and protein of each field. Or not only a tractor and a combine but an agricultural machine may be a rice transplanter. Further, the working machine may be applied not only to agricultural machines but also to backhoe construction machines. In the above-described embodiment, farm work data or the like is transmitted to the server 5 (work management support device) via the mobile terminal 4, but instead, the communication device 31 is replaced with a mobile communication network (for example, a mobile phone). It may be configured so that communication can be performed via a communication network), and farm work data or the like may be transmitted from the communication device 31 to the server 5.
