For example, when an operator or the like performs a predetermined operation on the work display device 10c1, the difference setting unit 34 displays the setting screen M3 as shown in FIG. 5A. On the setting screen M3, a figure D1 showing the tractor 1 (vehicle body 3), a figure D2 showing the work device 2, a figure D4 showing the mounting position of the position detection device 10a1, and a figure D5 showing a predetermined position of the work device 2 are displayed. indicate. On the setting screen M3, the difference setting unit 34 shows the figures D1 to D5 in two dimensions (plane).

The difference setting unit 34 inputs the difference (ΔX, ΔY) between the mounting position (X1, Y1) of the position detecting device 10a1 with respect to the working machine and the predetermined position (X2, Y2) of the working device 2 on the setting screen M3. The distance input unit 43 is displayed. The predetermined positions (X2, Y2) of the work device 2 are positions that can be arbitrarily set by the operator on the setting screen M3, and in FIG. 5A, the predetermined positions (X2, Y2) are the positions of the work device 2. An example is shown in which the central portion in the width direction and the rear end portion of the working device 2 are set.

When the input of the difference (ΔX, ΔY) to the setting screen M3 is completed, the display control unit 32 shifts the mounting position (X1, Y1) by ΔX in the X-axis direction and ΔY in the Y-axis direction to a predetermined position (X2, Y1). Y2) is set as the drawing start point P1. The drawing start point P1 can be changed by changing the value input to the distance input unit 43. That is, the display control unit 32 displays the setting screen M3, and on the setting screen M3, the relationship between the mounting position (X1, Y1) of the position detecting device 10a1 and the predetermined position (X2, Y2) of the working device 2. Can be set while the operator is looking at, so that the drawing start point P1 can be changed. The coordinates (numerical values) of the mounting positions (X1, Y1) of the position detection device 10a1 may be displayed on the setting screen M3.

As described above, when the setting of the drawing start point P1 by the display control unit 32 is completed, the graphic D3 indicating the changed drawing start point P1 is displayed in the field 40 of the guidance screen M1 (S11). That is, the display control unit 32 offsets the difference (ΔX, ΔY) detected by the difference setting unit 34 with respect to the detection position detected by the position detection device 10a1 to set a predetermined position (X2, Y2). Match the drawing start point P1.

In the above-described embodiment, the drawing start point P1 is changed based on the relationship between the mounting position of the position detection device 10a1 set on the setting screen M3 and the predetermined position of the work device 2, but the model of the work device 2 is changed. Changes may be made based on this.
The display control unit 32 has a model setting unit 35. The model setting unit 35 is composed of electrical, electronic components, programs, and the like provided in the work display device 10c1. The model setting unit 35 sets the model of the work device 2 as the work machine information. When an operator or the like performs a predetermined operation on the work display device 10c1, the model setting unit 35 displays the setting screen M4 as shown in FIG. 5B. On the setting screen M4, the model input unit 44 for inputting the model of the work device 2 is input. The model input unit 44 displays a list of models of the work device 2 registered in advance in the work display device 10c1. When a predetermined model is selected from the list of models displayed on the model input unit 44 and the input of the model to the model input unit 44 is completed, the model setting unit 35 sets the model input to the model input unit 44. (get.

As shown in FIG. 6, the storage unit 33 of the work display device 10c1 stores an offset amount (ΔX, ΔY) with respect to the mounting position of the position detection device 10a1 according to the model of the work device 2. For example, the offset amount (ΔX, ΔY) is set so that the drawing start point P1 is at the center of the work device 2 in the width direction and corresponds to the rear end of the work device 2.
The offset amount (ΔX, ΔY) may be set so that the drawing start point P1 coincides with the work position of the work unit that performs work on the ground (workplace) in the work device 2. The working part is the part that sprays fertilizer in the case of a fertilizer sprayer, the part of the nozzle that sprays the chemical in the case of a chemical sprayer, the part that sows seeds in the case of a sowing device, and the crop in the case of a harvester. It is a reaping part that reaps. The working unit is not limited to the above-mentioned example. In this embodiment, the offset amount (ΔX, ΔY) is set so that the working position of the nozzle 2b becomes the drawing start point P1.

When the model setting unit 35 acquires the model, the display control unit 32 extracts the offset amount corresponding to the acquired model, and subtracts the extracted offset amount from the mounting position of the position detection device 10a1 (X1-ΔX, Y1). −ΔY) is set at the drawing start point P1. For example, when the model is "KU-100", the offset amount ΔX is 100 cm and ΔY is 0 cm. In this case, in the field 40, the position 100 cm rearward from the mounting position of the position detecting device 10a1 is the drawing start point P1. As described above, since the display control unit 32 changes the drawing start point P1 based on the model acquired by the model setting unit 35, the travel locus W1 when working with the work machine is displayed in the field 40 according to the model. can do.

In the above-described embodiment, the offset amount (ΔX, ΔY) is set to match the working position of the working unit, but the offset amount (ΔX, ΔY) is input so that the worker can arbitrarily input the working position of the working unit. The drawing start point P1 may be set based on the working position.
For example, when an operator or the like performs a predetermined operation on the work display device 10c1, the display control unit 32 displays the setting screen M5 as shown in FIG. 5C. On the setting screen M5, a figure D1 showing the tractor 1 (vehicle body 3), a figure D2 showing the working device 2, and a figure D6 showing the working part of the working device 2 are displayed. On the setting screen M5, the display control unit 32 displays the position input unit 41. The position input unit 41 is a portion shown on the setting screen M5 for inputting the work position of the work unit of the work device 2. For example, the position input unit 41 inputs the work device of the work unit in the coordinate system (X3, Y3) or the like with the center of the work device 2 as the origin O1. When the input of the work position (X3, Y3) of the work unit is completed on the setting screen M5, the display control unit 32 sets the work position (X3, Y3) of the work unit to the drawing start point P1. That is, when the display control unit 32 acquires the work position (X3, Y3) of the work unit, the offset amount (X3-ΔX, Y3) between the work position (X3, Y3) of the work unit and the mounting position of the position detection device 10a1 −ΔY) is set at the drawing start point P1.

As described above, since the working position (X3, Y3) of the working unit can be set as the drawing start point P1, the drawing start point P1 of the traveling locus W1 when working with the work machine is the working position of the working unit. You can work while recognizing that there is.
By the way, as shown in FIG. 3, when the tractor 1 (working device 2) travels in the work place and the position (detection position) detected by the position detecting device 10a1 is changed (S12, Yes), the display control unit 32 Changes the depiction position of the first line L1 by scrolling the second line L2 of the field 40 in the vertical direction and scrolling the first line L1 of the field 40 in the horizontal direction according to the change in the detection position. (S13).

Further, the display control unit 32 displays the traveling locus W1 by coloring the color of the field 40 in the direction scrolled from the drawing start point P1 to a color different from other portions substantially at the same time as the scrolling operation (S14). .. For example, in the field 40, the display control unit 32 draws the traveling locus W1 by coloring the portion corresponding to the rear from the figure D2 showing the work device 2. The display control unit 32 makes the width of the traveling locus W1, that is, the coloring width of the field 40 match the working width.

Further, by performing a predetermined operation on the work display device 10c1 while drawing the traveling locus W1 of the tractor 1 (working device 2) in the field 40, that is, even while traveling, the drawing start point P1 It can be changed. For example, when the operator operates a switch or the like before or during the running of the tractor 1 (working device 2), the setting screens M3, M4, M5, etc. are displayed and depicted on the display unit 31 of the work display device 10c1. The starting point P1 can be changed.

In the above-described embodiment, the setting screens M3 to M5 are displayed on the display unit 31 of the work display device 10c1, and the information [position (distance), model, working position] to be input to the setting screens M3 to M5 is changed. Although the depiction position P1 has been changed, the depiction position P1 may be changed based on the work machine information transmitted from the work device 2.
As shown in FIG. 1, the working device 2 is provided with a communication device 50. The communication device 50 is a wireless tag, that is, an RFID tag (Radio Frequency Identification). The RFID tag stores the work position in the work unit of the work device 2 as work machine information.

The work display device 10c1 has a position acquisition unit 36. The position acquisition unit 36 is composed of an electric, electronic component, a program, and the like on the work display device 10c1. Specifically, the position acquisition unit 36 is a wireless tag reader that receives the working position of the working unit of the RFID tag 10, that is, an RFID reader. The RFID tag receives the radio wave transmitted from the RFID reader and transmits the working position toward the RFID reader 11. When the position acquisition unit 36 acquires the work position of the work unit, the display control unit 32 sets the acquired work position at the drawing start point P1. According to the above, the drawing start point P1 can be set only by connecting the working device 2 to the tractor 1.

The work display device 10c1 in the second embodiment may be a device that can change the drawing start point, but may be a device that cannot change the drawing start point. In the second embodiment, the description of the same configuration as that of the first embodiment will be omitted.

The work display device 10c1 in the second embodiment displays a warning when the actual remaining amount (actual remaining amount) of the material stored in the working machine and the theoretical remaining amount are different. Alternatively, the work display device 10c1 changes the display related to the work machine on the field 40 of the display unit 31 based on the actual remaining amount. The description of the same configuration as that of the first embodiment will be omitted.
The material is at least a substance to be put into the workplace, such as fertilizers, chemicals, seeds, seedlings and the like. The work device 2 is provided with a storage member for storing materials. The storage member is a support base for tanks, trays, etc., fertilizers, chemicals, seeds, etc. are stored in the tank, and seedlings, etc. are placed on the support base. In this embodiment, as shown in FIG. 16, the storage member is the tank 2a, and the drug is stored in the tank 2a as a material.

The case where there is a difference between the actual remaining amount and the theoretical remaining amount will be described below.
It has an actual remaining amount acquisition unit 37A, a theoretical remaining amount acquisition unit 38A, and a theoretical remaining amount calculation unit 39A. The actual remaining amount acquisition unit 37A, the theoretical remaining amount acquisition unit 38A, and the theoretical remaining amount calculation unit 39A are composed of electric, electronic parts, programs, and the like provided in the work display device 10c1.
The actual remaining amount acquisition unit 37A acquires the actual remaining amount (actual remaining amount) of the material stored in the work machine. As shown in FIG. 7, the working device 2 or the vehicle body 3 is provided with the remaining amount detecting device 13. The remaining amount detecting device 13 is a device that detects the actual remaining amount of the material stored in the storage member. The remaining amount detecting device 13 is provided outside or inside the storage member, and is a camera such as a CCD, an optical sensor, an electromagnetic sensor, a contact type sensor, or the like. The actual remaining amount acquisition unit 37A acquires the actual remaining amount detected by the remaining amount detecting device 13. In this embodiment, the remaining amount detecting device 13 detects the remaining amount of the drug remaining in the tank 2a as the actual remaining amount.

The theoretical remaining amount acquisition unit 38A acquires the theoretical remaining amount of the material used in the work of the working machine. For example, when an operator or the like performs a predetermined operation on the work display device 10c1, the display control unit 32 displays the setting screen M6 as shown in FIG. On the setting screen M6, a storage amount input unit 45 for inputting the storage amount of the material stored in the storage member and a supply amount input unit 46 for inputting the planned supply amount of the material per predetermined area are displayed. In the storage amount input unit 45, the storage amount of the material stored in the storage member at the time when the work is started or when the supply of the material is completed is input. The supply amount input unit 46 is a part for inputting the planned supply amount of the material to be supplied to the work place per predetermined area. For example, the planned supply amount of the material to be supplied per roll is input to the supply amount input unit 46.

The theoretical remaining amount calculation unit 39A calculates the theoretical remaining amount of the material based on the mileage of the work machine in the work place, the planned supply amount of the material per a predetermined area of the work place, and the storage amount stored in the work machine. Specifically, the theoretical remaining amount calculation unit 39A is the planned supply amount input to the supply amount input unit 46, the storage amount input to the storage amount input unit 45, and the tractor 1 (work) after the start of work or the start of replenishment. The theoretical remaining amount is calculated based on the mileage of the device 2) and the working width of the tractor 1 (working device 2) input to the width input unit 40.

As shown in FIG. 9, the theoretical remaining amount calculation unit 39A obtains the mileage Mi after the tractor 1 (working device 2) starts traveling from the transition of the position detecting device 10a1 (traveling locus W1 of the working machine). , The working area is obtained by multiplying the mileage Mi by the working width. The theoretical remaining amount calculation unit 39A obtains the theoretical usage amount from the ratio of the working area to the planned supply amount. For example, when the planned supply amount is 10 kg / roll and the working area is 0.5 rolls, the theoretical usage amount is 5 kg. The theoretical remaining amount calculation unit 39A obtains the theoretical remaining amount by subtracting the theoretical usage amount from the storage amount input to the storage amount input unit 45. The theoretical remaining amount acquisition unit 38A acquires the theoretical remaining amount obtained by the theoretical remaining amount calculation unit 39A. The display control unit 32 displays the theoretical remaining amount acquired by the theoretical remaining amount acquisition unit 38A on the theoretical remaining amount display unit 47 shown on the setting screen M6.

In the above-described embodiment, the mileage Mi is obtained from the transition of the position detection device 10a1, but the theoretical remaining amount calculation unit 39A may obtain the total area of the travel locus W1 of the work machine as the work area.
The work display device 10c1 has a remaining amount difference calculation unit 60A. It is composed of electric, electronic parts, programs and the like provided in the work display device 10c1. The remaining amount difference calculation unit 60A calculates the remaining amount difference between the actual remaining amount acquired by the actual remaining amount acquisition unit 37A and the theoretical remaining amount acquired by the theoretical remaining amount acquisition unit 38A. For example, when the actual remaining amount is 8 kg and the theoretical remaining amount is 7 kg, the remaining amount difference calculation unit 60A calculates that the remaining amount difference is 1 kg. Even when the actual remaining amount is 6 kg and the theoretical remaining amount is 7 kg, the remaining amount difference calculation unit 60A calculates that the remaining amount difference is 1 kg.

The display unit 31 of the work display device 10c1 displays at least a warning when the remaining amount difference calculated by the remaining amount difference calculation unit 60A is equal to or greater than a threshold value (deviation threshold value).
The divergence threshold is a value for determining that the difference between the actual remaining amount and the theoretical remaining amount is divergent. For example, when the numerical value of the material such as 1 kg or 2 kg or the maximum storage amount of the storage member is 100%. It is indicated by the ratio of materials such as 1 to 5%. Further, the deviation threshold value can be set by inputting to the work display device 10c1.

When the remaining amount difference calculated by the remaining amount difference calculation unit 60A is equal to or greater than the deviation threshold value, the display unit 31 causes the actual remaining amount and the theoretical remaining amount to deviate from each other on the guidance screen M1 as shown in FIG. Display a warning indicating that you are. The display unit 31 may display both the actual remaining amount and the theoretical remaining amount on the guidance screen M1.
Next, the display when the actual remaining amount is a predetermined threshold value (less than the holding threshold value) will be described.

The work display device 10c1 determines whether or not the actual remaining amount acquired by the actual remaining amount acquisition unit 37A is less than the threshold value (holding threshold value). When the actual remaining amount is less than the holding threshold value, the display unit 31 displays the position of the work machine whose actual remaining amount is less than the holding threshold value in the field 40 as the remaining amount lowering position (material lowering position) P2. The retention threshold is a value for determining that the actual remaining amount is small, and is indicated by, for example, a numerical value of a material such as 1 kg or 2 kg, or a ratio of a material such as 5% when the maximum storage amount of the storage member is 100%. .. Further, the holding threshold value can be set by inputting to the work display device 10c1.

As shown in FIG. 9, the display control unit 32 holds the detection position when the actual remaining amount of the material stored in the storage member becomes less than 5% of the maximum storage amount, and holds the detection position in the field 40. Information indicating that the actual remaining amount has decreased is displayed on the traveling locus W1 of the work machine at the position (remaining amount low position) P2 corresponding to the detection position. The display control unit 32 displays the graphic D7 indicating the decrease in the remaining amount at the remaining amount decrease position P2.

When the actual remaining amount is less than the holding threshold value, the remaining amount lowering position P2 is displayed in the field 40 by the figure D7, but when the actual remaining amount becomes zero (when it is completely exhausted), By displaying a figure different from the figure D7, a point where the actual remaining amount is completely zero may be positively indicated.
In the above-described embodiment, the figure D7 showing the remaining amount reduction position P2 is shown on the traveling locus W1 shown in the field 40, but even if the traveling locus W1 is displayed when the actual remaining amount is equal to or more than the holding threshold value. good.

FIG. 10 shows the guidance screen M7. As shown in FIG. 10, the display control unit 32 displays the traveling locus W1 in the field 40 of the guidance screen M7 when the actual remaining amount is equal to or greater than the holding threshold value. On the other hand, the display control unit 32 does not display the traveling locus W1 in the field 40 when the actual remaining amount is less than the holding threshold value. FIG. 11 is a diagram showing a flow of drawing the traveling locus W1 in the display control unit 32. In FIG. 11, S1 to S13 are the same as those in FIG.

The display control unit 32 refers to the actual remaining amount acquired by the actual remaining amount acquisition unit 37A, and determines whether or not the actual remaining amount is equal to or greater than the holding threshold value (S20). When the actual remaining amount is equal to or higher than the holding threshold value (S20, Yes), the display control unit 32 changes the color of the field 40 in the direction scrolled from the drawing start point P1 to a color different from that of the other parts substantially at the same time as the scrolling operation. By coloring, the traveling locus W1 is displayed (S21). On the other hand, when the actual remaining amount is less than the holding threshold value (S20, No), the display control unit 32 does not change the color of the field 40 at the drawing start point P1, that is, does not draw the traveling locus W1 in the field 40. (S22). By doing so, it is possible to grasp from the traveling locus W1 that the material has been exhausted. In other words, since the traveling locus W1 is displayed only when the material is put into the work place, the traveling locus W1 in the above-described embodiment can be regarded as a work locus indicating a place where the work is actually performed.

FIG. 12 is a modified example of the second embodiment, and shows a work management system including the management device 61. The management device 61 is a computer such as a server. The management device 61 has a communication device 62 and a storage unit 63.
The communication device 62 is a communication module that performs wireless communication via a mobile phone communication network and a communication module that performs wireless communication via a data communication network. The storage unit 63 stores at least a work plan for performing work in the workplace.

The working machine has a communication device 64. The communication device 64 is a communication module that performs wireless communication by Wi-Fi (WireNess FideNity, registered trademark) of the IEEE802.11 series, which is a communication standard, a communication module that performs wireless communication by a mobile phone communication network, and wireless by a data communication network. A communication module or the like that performs communication. The communication device 64 is connected to the vehicle-mounted network N1 and can transmit information on the work machine to the management device 61. Further, the communication device 64 can receive various information from the communication device 62 of the management device 61.

The management device 61 includes an actual remaining amount acquisition unit 37B, a theoretical remaining amount acquisition unit 38B, a theoretical remaining amount calculation unit 39B, and a remaining amount difference calculation unit 60B. The actual remaining amount acquisition unit 37B, the theoretical remaining amount acquisition unit 38B, the theoretical remaining amount calculation unit 39B, and the remaining amount difference calculation unit 60B are composed of electric, electronic parts, programs, and the like provided in the management device 61.
The actual remaining amount acquisition unit 37B acquires the actual remaining amount stored in the storage member of the working machine from the working machine. For example, when the remaining amount detecting device 13 of the working machine detects the actual remaining amount, the communication device 64 transmits the identification information of the working machine (working device 2) and the like, together with the actual remaining amount, and the actual remaining amount detected in the communication device 62. To send. When the communication device 62 of the management device 61 receives the actual remaining amount, the actual remaining amount acquisition unit 37B holds the received actual remaining amount. Therefore, the management device 61 (actual remaining amount acquisition unit 37B) can identify the work device 2 from the identification information.

The theoretical remaining amount acquisition unit 38B acquires the theoretical remaining amount obtained by the theoretical remaining amount calculation unit 39B. The theoretical remaining amount calculation unit 39B calculates the theoretical remaining amount based on the work plan stored in the storage unit 63 of the management device 61 and the mileage Mi acquired from the work machine. Specifically, as shown in FIG. 13, the storage unit 63 of the management device 61 uses the time such as the date on which the work is performed, the work place where the work is performed, the planned supply amount of materials to be supplied to the work place, and the work place as the work plan. The work equipment to be used, the storage amount of materials, and the work width are stored. In the work plan, the management device 61 can obtain a work plan by connecting an external terminal 80 such as a mobile terminal to the management device 61 and inputting various information on the work plan screen shown on the mobile terminal. can. The storage amount of the material is the amount of the material to be stored in the storage member at the start of the work, and can be determined at the time of the work plan.

The theoretical remaining amount calculation unit 39B refers to the storage unit 63 and acquires the planned supply amount, the storage amount, and the work width from the work plan corresponding to the work performed by the current work machine (working device 2). Here, since the identification information is received when the theoretical remaining amount acquisition unit 38B acquires the actual remaining amount, at least the current working machine (working device 2) can be specified. Therefore, since the work device 2 performing the current work can be extracted from the identification information, the work plan including the work device 2 having the identification information can be extracted from the plurality of work plans to present the current work. It is possible to obtain the planned supply amount, storage amount and work width in the work of.

In the above-described embodiment, the storage amount and the work width in the work plan are acquired by using the identification information acquired by the management device 61 together with the actual remaining amount as a key, but instead of this, the communication device 64 detects the position. By transmitting the detection position detected by the device 10c1 to the management device 61 (actual remaining amount acquisition unit 37B), the position of the field where the working machine (working device 2) is working can be grasped. Therefore, using the position of the field as a key, items related to the current work (planned supply amount, storage amount, and work width) may be acquired from the work plan.

Next, the theoretical remaining amount calculation unit 39B acquires the mileage Mi transmitted from the communication device 64 and obtains the working area by multiplying the mileage Mi by the working width. Further, the theoretical remaining amount calculation unit 39B obtains the theoretical usage amount from the ratio of the working area to the planned supply amount, and obtains the theoretical remaining amount by subtracting the theoretical usage amount from the storage amount.
The remaining amount difference calculation unit 60B calculates the remaining amount difference between the actual remaining amount acquired by the actual remaining amount acquisition unit 37B and the theoretical remaining amount acquired by the theoretical remaining amount acquisition unit 38B, and calculates the remaining amount difference. It is transmitted to the work equipment side (communication device 64) via the communication device 62. According to this, the remaining amount difference calculated by the management device 61 can be acquired on the working machine side. When the remaining amount difference calculated by the remaining amount difference calculation unit 60B is equal to or greater than the deviation threshold value, the display unit 31 of the work display device 10c1 indicates that the actual remaining amount and the theoretical remaining amount deviate from each other on the guidance screen M1. Display a warning indicating.

As described above, according to the above-described modification, the management device 61 has an actual remaining amount acquisition unit 37B, a theoretical remaining amount acquisition unit 38B, and a theoretical remaining amount calculation unit 39B. Therefore, the theoretical remaining amount can be calculated by the management device 61 outside the work machine, and the calculation load on the work machine side can be reduced.
Further, the management device 61 has a remaining amount difference calculation unit 60B. Therefore, the remaining amount difference can be calculated by the management device 61, and the calculation load on the working machine side can be reduced. As described above, when the management device 61 side has a work plan, the remaining amount difference can be easily calculated by using the work plan or the like, and the actual remaining amount acquisition unit 37A and the theoretical remaining amount acquisition unit 38A. And even a work machine that does not have the theoretical remaining amount calculation unit 39A and the remaining amount difference calculation unit 60A can display a warning indicating that the actual remaining amount and the theoretical remaining amount are different from each other.
[Third Embodiment]
FIG. 14 is a work management system according to the third embodiment. The work management system of the third embodiment is a system that stores at least the material shortage position in the management device 61. In the third embodiment, the description of the same configuration as that of the above-described embodiment will be omitted.

As shown in FIG. 14, the management device 61 has an actual remaining amount acquisition unit 37B and a storage unit 66. Specifically, when the work of the tractor 1 (working device 2) is started, at least the detection position detected by the position detecting device 10a1 and the actual remaining amount detected by the remaining amount detecting device 13 are managed from the communication device 64. It is transmitted to the device 61. The detection position and the actual remaining amount are transmitted at predetermined intervals or continuously in real time.

The actual remaining amount acquisition unit 37B of the management device 61 acquires the detection position and the actual remaining amount transmitted from the communication device 64. The storage unit 66 stores the detection position and the actual remaining amount acquired by the actual remaining amount acquisition unit 37B as actual amount information. The communication device 64 transmits the time (month, day, time) and the like when the position detection device 10a1 detects the detection position to the management device 61 together with the detection position, and the storage unit 66 transmits the time, the position detection position, and the actual balance. The amount may be stored as actual information.

In the management device 61, whether the actual remaining amount is less than the holding threshold value when the actual remaining amount acquisition unit 37B acquires the detection position and the actual remaining amount, or after storing the detected position and the actual remaining amount in the storage unit 66. Whether or not it is determined, and the detection position where the actual remaining amount is less than the holding threshold value is stored in the storage unit 66 as the remaining amount lowering position P2. In this way, at least the remaining amount low position P2 can be stored in the management device 61.

By the way, the remaining amount low position P2 or the like may be displayed on the external terminal 80 different from the management device 61. The external terminal 80 is, for example, a fixed terminal such as a personal computer, a mobile terminal such as a smartphone, a tablet, or a PDA, and is an extinction located at a place away from the work machine and the management device 61.
The external terminal 80 has a display unit 81. The display unit 81 is a device that displays various information related to the work. As shown in FIG. 15, for example, the display unit 81 displays the work screen M8. On the work screen M8, a field map 82 showing the field H1 registered in the external terminal 80 or the management device 61 is displayed. On the field map 82, the traveling locus W1 on which the tractor 1 (working device 2) has traveled is superimposed and displayed. Further, the remaining amount reduction position P2 is displayed on the field map 82. On the work screen M8, it is possible to specify at what time the work is to be displayed. For example, the time, day, week, month range, present, etc. can be specified by the time designation unit 83. .. When the present is designated by the time designation unit 83, for example, it is possible to display the work of one day (24 hours) retroactively from the present.

Specifically, when the external terminal 80 is connected to the management device 61, the management device 61 displays the work screen M8 on the display unit 81. For example, when the current time is set in the time designation unit 83 of the display unit 81, the management device 61 refers to the detection position and the actual remaining amount stored in the storage unit 66 within 24 hours retroactively from the present. .. The management device 61 causes the field map 82 to display the travel locus W1 on which the tractor 1 (working device 2) traveled, which is obtained from the detection position. Further, the management device 61 determines whether or not the actual remaining amount acquired by the actual remaining amount acquisition unit 37B is less than the holding threshold value, and lowers the remaining amount at the detection position when the actual remaining amount becomes less than the holding threshold value. It is displayed on the field map 82 as the position P2.

In this way, when the worker looks at the display unit 81 of the external terminal 80, he / she can not only grasp the traveling locus W1 when working with the work machine, but also grasp the position where the remaining amount of the material is low. can. If the remaining amount low position P2 is displayed on the work display device 10c1 provided on the work machine 1, while the remaining amount low position P2 is displayed on the external terminal 80, the driver operating the work machine and the driver operating the work machine can be displayed. It is possible for both the worker who is working outside the work machine to know that the amount of materials stored in the work machine 1 is low.

In the third embodiment described above, after the actual remaining amount is transmitted from the working machine side (communication device 64) to the management device 61, the remaining amount lowering position P2 in which the actual remaining amount is less than the holding threshold is set on the management device 61 side. Although it is judged, instead of this, the working machine side may make a judgment. For example, the work display device 10c1 is provided with the actual remaining amount acquisition unit 37A, and the work display device 10c1 determines whether or not the actual remaining amount acquired by the actual remaining amount acquisition unit 37A is less than the holding threshold value. Then, the work display device 10c1 sets the detection position at the time when the actual remaining amount becomes less than the holding threshold value at the remaining amount lowering position P2. The communication device 64 transmits the remaining amount low position P2 to the management device 61, and the management device 61 stores the remaining amount low position P2 in the storage unit 66. In this way, the working machine side can obtain the remaining amount reduction position P2 and transmit the obtained remaining amount reduction position P2 to the management device 61.

In the above-described embodiment, the working machine has been described by taking the tractor 1 equipped with the working device 2 as an example, but the above-described configuration can also be applied to a rice transplanter as shown in FIG. As shown in FIG. 17, the rice transplanter 17 includes a vehicle body 3, a prime mover 4 provided on the vehicle body 3, and a transmission 5 provided on the vehicle body 3. The vehicle body 3 is composed of a combination of a plurality of frames and supports a wheel-type traveling device. The vehicle body 3 can travel by the traveling device. A work device 2 such as a fertilizer spraying device and a sowing device is provided on the rear side of the vehicle body 3. Further, a seedling loading table 11 and a seedling planting device 12 are provided on the rear side of the vehicle body 3. The rice transplanter 17 is provided with the above-mentioned position detection device 10a1, the above-mentioned work display device 10c1, and the like. When applied to the rice transplanter 17, the above-mentioned tractor 1 may be read as “rice transplanter 17”.

Therefore, also in the rice transplanter 17, the drawing start point P1 of the position to the fold 40 is changed based on the information about the rice transplanter 17, and the remaining amount difference calculated by the remaining amount difference calculation units 60A and 60B is equal to or more than the threshold value. At least a warning can be displayed in some cases.
