For example, as described above, the display device 32 controls the display of the first line L1 and the second line L2, the scrolling of the field 40, the display of the icon portion 41, the display of the locus W1 of position, and the like.

FIG. 3 is a diagram showing the flow of control in the display control unit 32. As shown in FIG. Control of the display control unit 32 will be described based on FIG. 3.
When displaying the first line L1, the display control unit 32 determines the separation distance of the first line L1 on the guidance screen M1 (S2: distance setting process). The distance setting process S2 is performed based on the work width included in the device information transmitted by the communication device 50. For example, when the receiving device 16 receives the device information, the working width included in the device information is extracted, and at least the working width is determined as the separation distance. In the work display device 10c1, when the overlap width is input, the display control unit 32 subtracts the overlap width from the work width to determine the separation distance between the adjacent first lines L1.

  Further, when the first icon part 41a and the second icon part 41b are selected (S3, Yes), the display control part 32 displays the figures A and B of the first point and the second point (S4). When the first icon portion 41a and the second icon portion 41b are selected, the position (set position) detected by the position detection device 10a1 is stored in the storage unit 33 of the work display device 10c1. In the field 40, positions corresponding to the first point and the second point are set as set positions. That is, a position (latitude, longitude) based on the set position is allocated on the field 40.

  In addition, when the third icon portion 41c is selected (S5, Yes), the display control unit 32 draws a plurality of first lines L1 on a straight line passing through the first point and the second point in the field 40 (S6) ). On the other hand, when the fourth icon portion 41d is selected (S7, Yes), the display control unit 32 draws a plurality of curved first lines L1 passing through the first point and the second point in the field 40 (S8) ). Note that, when the plurality of first lines L1 are drawn in the width direction, the display control unit 32 sets the distance between adjacent first lines L1 to the separation distance determined in the distance setting process S2.

  Now, 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 detection device 10a1 is changed (S12, Yes), the display control unit 32 Scrolls the second line L2 of the field 40 in the vertical direction, and horizontally scrolls the first line L1 of the field 40 according to the change in the detection position, thereby changing the position of the depiction of the first line L1. To do (S13).

In addition, the display control unit 32 displays the traveling locus W1 by coloring the color of the field 40 in the direction which is scrolled from the depiction start point P1 substantially at the same time as the scroll operation (S14). . For example, in the field 40, the display control unit 32 draws a traveling locus W1 by coloring a portion corresponding to the rear from the figure D2 indicating the working device 2.
Therefore, according to the work display device 10c1, the position detected by the position detection device 10c1, that is, the traveling locus W1 can be displayed, and since the reception device 16 is provided, the device transmitted from the communication device 50 Information can be received.

Now, as shown in FIG. 1, the work management system includes a management apparatus 150. The management device 150 is a computer different from the device mounted on the work machine, and is, for example, a server or the like.
The management device 150 includes a reception unit 151, an evaluation unit 152, and a transmission unit 153. The receiving unit 151, the evaluating unit 152, and the transmitting unit 153 are configured by electricity, electronic components, programs, and the like provided in the management device 150.

  The receiving unit 151 receives the device information received by the receiving device 16. For example, when the communication device 50 and the receiving device 16 become communicable with each other by the work device 2 being connected to the vehicle body 3 of the tractor 1, the receiving device 16 receives the device information. The receiving device 16 outputs the device information to the in-vehicle network N1 etc. irregularly or periodically, and the communication device 10e transmits the device information acquired from the in-vehicle network N1 etc. to the management device 150. The receiving unit 151 receives the device information transmitted from the communication device 10 e.

The evaluation unit 152 evaluates the work of the work device 2 based on the device information received by the reception unit 151. For example, the evaluation unit 152 evaluates the work of the work device 2 based on the work machine, that is, the work plan of the work performed by the work device 2. The transmission unit 153 transmits the evaluation of the evaluation unit 152.
The evaluation of the work device 2 by the work plan and transmission of the evaluation will be described in detail.

  The management device 150 includes a work plan creation unit 155 and a storage unit 156. The work plan creation unit 155 is configured by electricity, electronic components, programs and the like provided in the management device 150. The work plan creation unit 155 creates a work plan. The storage unit 156 is configured by a non-volatile memory or the like and stores at least a work plan. The work plan is a plan related to agricultural work performed at a work place such as a field. Farming work is, for example, floor soil making, visco-coating, tilling, rice planting, scraping, grooving, weeding, harvesting, sowing, fertilizing, applying medicine, and the like.

  When the worker computer 171 or the administrator computer is connected to the management apparatus 150 and there is a request for creating a work plan for the worker computer 171 or the administrator computer 172, the work plan creation unit 155 is made in response to this request. As shown in FIG. 4, a plan setting screen M20 for making a work plan is displayed on the worker computer 171 or the manager computer 172. The worker computer 171 and the administrator computer 172 are a personal computer, a smartphone, a tablet, and the like.

The plan setting screen M20 sets a date setting unit 160 for setting a date for performing an agricultural work, a work place setting unit 161 for setting a workplace, a work setting unit 162 for setting an agricultural work (work items for agricultural work), and a farmer It includes a worker setting unit 163, a time setting unit 164 for setting a working time, and a machine setting unit 165 for setting a working device.
A map of the work place is displayed on the work place setting unit 161, and by selecting the work place shown on the map, it is possible to set a work place to be operated. The work setting unit 162 can select or input various work operations (bed soil formation, gravel coating, tilling, rice planting, scraping, cutting, weeding, harvesting, sowing, fertilization, medicine operation items, ie, work items). is there.

  The worker setting unit 163 displays the list of worker names (farm worker names) registered in advance in the management apparatus 150, the administrator computer 171, the worker computer 172, etc. The worker can be determined by selecting from the list. Further, the time setting unit 164 can set a time zone in which the farm work is performed. The machine setting unit 165 can input the model, model number, model etc. of the work device.

Therefore, by connecting the worker computer 171 or the manager computer 172 to the management apparatus 150, a work plan can be created, and the created work plan can be stored in the storage unit 156.
FIG. 5 is a diagram showing a flow of evaluation by the evaluation unit 152 based on the device information and the work plan. The apparatus information is a model number or the like, and the description will be made assuming that the work place is a field.

  The communication device 50 transmits the model number to the outside at predetermined intervals (S51). When receiving the model number transmitted from the communication device 50 (S52, Yes), the receiving device 16 transmits the received model number to the communication device 10e via the in-vehicle network N1 (S53). The communication device 10e transmits the model number and the detected position detected by the position detection device 10c1 to the management device 150 (S54). The management device 150 acquires the model number and the detection position transmitted from the communication device 10e, and stores the model number and the detection position in the storage unit 156 (S55).

  The model number and the detection position by the communication device 10 e may be transmitted to the management device 150 via the computer 171 for workers. For example, at the start of work, the worker computer 171 and the communication device 10e are connected, and the worker computer 171 receives the model number and the detected position from the communication device 10e. The worker computer 171 transmits the received model number and detected position to the management apparatus 150 after receiving the model number and detected position.

Thus, the management device 150 can grasp the model number and the position of the work device 2 transmitted from the work machine.
The evaluation unit 152 refers to the work plan stored in the storage unit 156, and extracts the current work plan (S56). Further, the model number and the detection position of the working device 2 at the current time (time, date, etc.) are extracted with reference to the storage unit 156 of the management device 150 (S57). For example, when the current time is September 5, the evaluation unit 152 extracts the work plan of September 5 and extracts the model number and detection position of the work device 2 acquired by the management device 150 on September 5 Do.

  The evaluation unit 152 compares the detected position with the position of the field to obtain the field where the work machine (the work device 2) is working (S58). For example, the evaluation unit 152 finds a field where the work machine (work device 2) is performing work by specifying a field including the detected position from among a plurality of fields registered in advance in the management device 150. . Hereinafter, for convenience of explanation, the field where the work machine (work device 2) is working is referred to as "field during work" and the work machine (work device 2) working in the field during work It is called "machine during work".

  The evaluation unit 152 extracts a work plan including a field during work from the work plans set to the current date (S59). That is, when there is a work plan for farmland A, farmland B, and farmland C, if the farmland is farmland C during the operation, the evaluation unit 152 extracts the work plan corresponding to farmland C. Hereinafter, for convenience of explanation, the work plan including the field during work is referred to as “the present plan”.

  The evaluation unit 152 refers to the model number set in the current plan (S60), and compares the model number set in the current plan (referred to as the planned model number) with the model number of the machine under work (referred to as the current model number) (S61) ). If the planned model number and the current model number match (S61, Yes), the evaluation unit 152 evaluates that the operation of the machine during operation is good (S62). When the planned model number and the current model number do not match (S61, No), the evaluation unit 152 evaluates that the operation of the machine during operation is defective (S63).

After the evaluation by the evaluation unit 152, the transmission unit 153 transmits the evaluation of the evaluation unit 152 to the working machine (S64). For example, the transmitting unit 153 transmits the evaluation to the communication device 10 e of the working machine.
When the communication device 10e of the working machine receives the evaluation, the evaluation is displayed on the work display device 10c1 of the working machine. If the evaluation is good, for example, it is displayed on the work display device 10c1 of the working machine that the work is being performed by the work device 2 as scheduled. On the other hand, if the evaluation is not good, for example, it is displayed that the work device 2 different from the work plan is mounted on the work display device 10c1 of the working machine.

  The control device 10 d changes the control of at least one of the vehicle body 3 and the work device 3 based on the evaluation transmitted from the transmission unit 153. The control device 10d includes a first control unit 10d1 that performs control based on the evaluation of the evaluation unit 152, and a second control unit 10d2 that performs control based on the operation of the steering device 18. The first control unit 10d1 and the second control unit 10d2 are configured by electricity, electronic components, programs and the like provided in the control device 10d.

  It is possible to switch the effectiveness or ineffectiveness of the control by the first control unit 10d1 by operating the work display device 10c1 or the like. The work display device 10c1 can display a setting screen for setting whether to enable or disable the control by the first control unit 10d1. In the setting screen, when the control of the first control unit 10d1 is set to be effective, the control by the first control unit 10d1 is effective. That is, when the first control unit 10d becomes effective, it is possible to change the control based on the evaluation.

  When the first control unit 10d1 is set to be invalid on the setting screen, the control by the first control unit 10d1 is invalidated. When the first control unit 10d1 becomes ineffective, the control by the second control unit 10d2 becomes effective. When the control of the second control unit 10d2 becomes effective, the second control unit 10d performs elevation control, travel control, and the like as described above according to the operation of the operation control device or the travel control device, and control based on evaluation. No change is made.

Next, control based on evaluation will be described for the case where the first control unit 10d1 is enabled.
When the first control unit 10d1 has a favorable evaluation, the first control unit 10d1 does not change the control of the vehicle body 3 or the work device 2. On the other hand, the first control unit 10d1 changes the control of the vehicle body 3 or the work device 2 when the evaluation is poor. Specifically, the control device 10d stores the work conditions in the plurality of work devices 2, that is, the work conditions for each model number, and changes the control of the vehicle body 3 or the work device 2 based on the work conditions. The working condition is a condition determined for each working device 2 and, for example, the working speed corresponding to the working device 2 for the working device 2 is the working speed (upper limit or lower limit of vehicle speed, recommended speed of vehicle speed, etc.) Are stored in the control device 10d as work condition information. In addition to this, the work conditions are work height [upper limit or lower limit of spray height of fertilization, upper limit or lower limit of spray height of medicine, upper limit or lower limit of depth of tillage depth], and the like.

  For example, when the work device 2 mounted on the machine during work has the upper limit of the vehicle speed determined, the first control unit 10d1 sets the upper limit of the vehicle speed and controls the transmission 5 or the travel device, The vehicle speed during the operation of the work device 2 of the machine during operation does not exceed the upper limit.
