For example, as shown in FIG. 7B, the moisture map creating unit 87 determines whether or not the first moisture value and the cutting position detected in the cutting operation on May 21 are stored in the storage unit 84c. When the first moisture value and the cutting position in the cutting operation on 5/21 are stored in the storage unit 84c, the moisture map creating unit 87 creates the moisture map 110A in which the first moisture value and the cutting position correspond to each other. .. In the creation of the moisture map 110A, the moisture map creation unit 87 sets in advance the levels indicating the high and low moisture values in several stages (for example, four stages), and maps the moisture values corresponding to each level. Alternatively, the moisture value itself may be represented as a map, or the average value of the moisture values in a predetermined range may be represented as a map, and the method of creating the moisture map 110A by the moisture map creating unit 87 is limited to the above-mentioned method. Not done.

Therefore, at least on the creation screen M2 for setting the work plan after cutting, the water content map 110A at the time of cutting work is displayed. Therefore, for example, in the date schedule unit 105 of the creation screen M2, when the administrator or the like can manually change the relationship between the work and the date, the administrator can arbitrarily change the date of the diffusion work while referring to the moisture map 110A. Can be changed.
For example, when the moisture value displayed on the moisture map 110A is lower than a predetermined value, the working period of the diffusion work in the date schedule portion 105 is shortened. On the other hand, when the moisture value displayed on the moisture map 110A is higher than a predetermined value, the working period of the diffusion work in the date schedule portion 105 can be lengthened. In FIG. 7B, the work period of the diffusion work (work plan of FIG. 7A) set at the time of planning the cutting work is extended by one day from “5/22 to 5/24” to “5/22 to 5/25”. Is shown.

In the above-described embodiment, the administrator or the like looks at the moisture map 110A displayed on the creation screen M2 and arbitrarily changes the date shown in the date schedule section 105 of the creation screen M2, but the creation support section 85 The date of work in the work plan may be set based on the first moisture value.
The creation support unit 85 extracts the first moisture value in the field A (predetermined field) acquired in the cutting operation from the storage unit 84c. For example, the creation support unit 85 obtains the average value (actual moisture value) of the first moisture value in the field A, and compares the actual moisture value with the set value (target moisture value) set by the support device 84 or the like. .. When the moisture difference between the actual moisture value and the target moisture value (actual moisture value-target moisture value) is large in the brass direction, the creation support unit 85 sets a long working period for the diffusion work, and sets the actual moisture value and the target. If the water difference from the water value is large in the negative direction, set the working period of the diffusion work short. The creation support unit 85 does not change the working period of the diffusion work when there is almost no water difference between the actual water value and the target water value and it is within a predetermined range. The creation support unit 85 changes the date by displaying the work period of the diffusion work obtained by the first moisture value on the recommended display unit 104 or by applying the work period of the diffusion work to the date schedule unit 105.

In this way, the creation support unit 85 can change (adjust) the work period of the diffusion work according to the first moisture value. Therefore, even if the manager or the like is not an expert, the diffusion work can be adjusted. When the work period is displayed on the recommended display unit 104, the final work period can be set with reference to the work period displayed on the recommended display unit 104.
The creation support unit 85 may set the number of operations in the work plan based on the first moisture value. FIG. 7C shows a modified example of the date schedule portion 105 on the creation screen. The date schedule unit 105 can set the number of times the work is performed on the same date. The date schedule unit 105 can set at least the number of diffusion operations. For example, when the diffusion work on 5/22 is selected, the number of times in the diffusion work on the selected date can be arbitrarily set.

For example, it is assumed that the number of diffusion operations is set to a plurality of times in advance on the date schedule unit 105 of the creation screen M1 for setting the cutting operation. After that, when the creation screen M2 is displayed after the cutting work is completed, the creation support unit 85 calculates the moisture difference between the actual moisture value and the target moisture value, and if the moisture difference is large in the brass direction, Increase the number of times in the diffusion work, and decrease the number of times in the diffusion work when the water difference between the actual water value and the target water value is large in the negative direction. The creation support unit 85 does not change the number of times in the diffusion work when there is almost no difference in moisture between the actual moisture value and the target moisture value and it is within a predetermined range.

In the above-described embodiment, the creation support unit 85 automatically changes the number of diffusion operations, but the administrator or the like manually arbitrarily changes the number of diffusion operations on the same date while looking at the moisture map 110A. You may change it.
The creation support unit 85 may set the work date based on the moisture map 110A. As shown in FIG. 8, in the moisture map 110A, when the first moisture value in the predetermined area A1 at the time of cutting work is biased higher than the other portions, the creation support unit 85 has the first moisture in the predetermined area A1. Calculate the moisture difference between the value and the target moisture value. The creation support unit 85 sets a long working period for the diffusion work when the water difference in the predetermined area A1 is large in the brass direction, and when the water difference between the actual water value and the target water value is large in the negative direction. Sets the work period of diffusion work short. For example, the work period of diffusion work (work plan of FIG. 7A) can be lengthened from "5/22 to 5/24" to "5/22 to 5/25", or the work period of diffusion work (work plan of FIG. 7A) can be extended. ) Is shortened from "5/22 to 5/24" to "5/22 to 5/23".

According to this, when there is a predetermined area A1 having a high water content in the predetermined field (field A), the work period (days) is changed based on the predetermined area A1 to change the grass after the cutting work. It is possible to prevent the moisture value from being biased.
The creation support unit 85 may set the number of operations based on the moisture map 110A. FIG. 8
As shown in the above, when the first moisture value in the predetermined area A1 at the time of cutting work is biased higher than other parts in the moisture map 110A, the creation support unit 85 increases the number of diffusion operations on the same date. Let me. For example, the number of diffusion operations of "5/22" in FIG. 7C is increased from "2 times" to "3 times". In the above-described embodiment, the number of diffusion operations on the same date is increased, but instead, the number of diffusion operations only in the predetermined area A1 having a high first moisture value during the cutting operation may be increased. Good. For example, the predetermined area A1 that increases the number of times of diffusion work is highlighted and displayed on the moisture map 110A, and the number of times of diffusion work in the predetermined area A1 is displayed.

According to this, when there is a predetermined area A1 having a high water content in the predetermined field (field A), the water content of the grass after the cutting work is biased by increasing the diffusion work only in the predetermined area A1. It is possible to prevent it from being stored.
FIG. 9A shows a creation screen M3 which is a modification of the creation screen M1. As shown in FIG. 9A, the weather map 101, the weekly weather forecast 102, the work item unit 103, and the recommended display unit 104 are displayed on the creation screen M3.

The creation support unit 85 displays the time schedule unit 107 that displays the time (time) for performing the work corresponding to each work item. The creation support unit 85 assigns work items (work) to work time (work time width) based on the recommended date selected by the recommended display unit 104. The work time is allocated by the creation support unit 85 based on the relationship between the work and the work time. Here, as for the relationship between the work and the work time, the standard work time may be registered in the support device 84 in advance for each work, or the work time is obtained by obtaining the relationship between the work and the work time from the past results. , Or the work time may be allocated based on the relationship between the work and the work time obtained by other methods.

In the above-described embodiment, the creation support unit 85 automatically creates the relationship between the work and the work time in the time schedule unit 107, but the administrator or the like operates the support device 84 to arbitrarily create the time schedule. The relationship between the work and the work time in the unit 107 may be set, and is not limited to the above-described embodiment. When the button (registration button) 106 displayed on the creation screen M3 is selected, the work plan set on the creation screen M3 is stored in the storage unit 84c of the support device 84.

FIG. 9B shows a creation screen M4 which is a modification of the creation screen M2. As shown in FIG. 9B, the moisture map 110A is displayed on the creation screen M4. Therefore, at least the water content map 110A at the time of cutting work is displayed on the creation screen M4 for setting the work plan after cutting. Therefore, for example, when the relationship between the work and the work time can be arbitrarily changed in the time schedule unit 107 of the creation screen M4, the administrator can arbitrarily change the work time of the diffusion work by referring to the moisture map 110A. .. For example, when the water content displayed on the water content map 110A is lower than a predetermined value, the working time of the diffusion work in the time schedule unit 107 is shortened. On the other hand, when the water content displayed on the water content map 110A is higher than a predetermined value, the working time of the diffusion work in the time schedule unit 107 can be lengthened.

Therefore, at least the water content map 110A at the time of cutting work is displayed on the creation screen M4 for setting the work plan after cutting. Therefore, for example, in the time schedule unit 107 of the creation screen M4, the administrator can manually and arbitrarily change the work time of the diffusion work while referring to the water content map 110A.
In the above-described embodiment, the moisture map 110A is displayed on the creation screen M4, and the administrator or the like arbitrarily changes the work time shown in the time schedule unit 107 of the creation screen M4, but the creation support unit 85 is the first. 1 The working time in the work plan may be set based on the water content. The creation support unit 85 compares, for example, the actual moisture value in the field A with the target moisture value. When the moisture difference between the actual moisture value and the target moisture value is large in the brass direction, the creation support unit 85 sets a long working time for the diffusion work, and the moisture difference between the actual moisture value and the target moisture value is negative. If it is large in the direction, set the working time of the diffusion work short. The creation support unit 85 does not change the working time of the diffusion work when there is almost no water difference between the actual water value and the target water value and it is within a predetermined range. The creation support unit 85 changes the work time by displaying the work time of the diffusion work obtained by the first moisture value on the recommended display unit 104 or by applying the work time of the diffusion work to the time schedule unit 107. ..

In this way, the creation support unit 85 can change (adjust) the working time of the diffusion work according to the first moisture value. Therefore, even if the manager or the like is not an expert, the diffusion work can be adjusted. Further, when the working time is displayed on the recommended display unit 104, the final working time can be set with reference to the working time displayed on the recommended display unit 104.
The creation support unit 85 may set the work date based on the moisture map 110A. As shown in FIG. 8, in the moisture map 110A, when the first moisture value in the predetermined area A1 at the time of cutting work is biased higher than the other portions, the creation support unit 85 has the first moisture in the predetermined area A1. Calculate the moisture difference between the value and the target moisture value. The creation support unit 85 sets a long working time for the diffusion work when the water difference in the predetermined area A1 is large in the brass direction, and when the water difference between the actual water value and the target water value is large in the negative direction. Sets the working time of diffusion work short.

According to this, when there is a predetermined area A1 having a high moisture value in the predetermined field (field A), the moisture value of the grass after the cutting work is increased by changing the working time based on the predetermined area A1. It is possible to prevent bias.
In the above-described embodiment, changes in the work plan (change of date, change of number of times, change of time, etc.) in the diffuser 1B have been described based on the first moisture value or the moisture map, but other than the diffuser 1B. It can be applied to change the work plan of the grass collector 1C and the molding machine 1D. In this case, the diffuser 1B may be read as "grass collector 1C" or "molding machine 1D", and the diffusion work may be read as "grass collecting work" or "molding work". Further, based on the first moisture value or the moisture map, the work plan in the work (diffusion work, weed collection work, molding work) performed after the cutting work may be changed in a complex manner.

The creation support unit 85 may set a traveling route in the work machine based on the moisture map 110A. FIG. 10 shows an example of the creation screen M5 for setting a traveling route in the diffusion work. On the creation screen M2, when the work item "diffusion work" shown in the work item unit 103 is selected and the travel setting unit 108 is selected, the creation support unit 85 displays the creation screen M5 on the display unit 84b. The moisture map 110A is displayed on the creation screen M5. On the moisture map 110A, the traveling route R1 of the diffuser 1B that performs the diffusion work is displayed. The creation support unit 85 sets the travel route of the diffuser 1B according to the level of the first moisture value in the moisture map 110A. For example, when the level of the first moisture value is four stages (level 1 to level 4), the creation support unit 85 has the region Q1 corresponding to the lowest level 1 of the first moisture value in the moisture map 110A. Region Q2 where the level of the first moisture value corresponds to a level one step higher than level 1, region Q3 where the level of the first moisture value corresponds to a level one step higher than level 2, and the level of the first moisture value is the level. The traveling route R1 of the diffuser 1B is set in the order of the region Q4 corresponding to the level one step higher than 3, and the set traveling route R1 is displayed on the creation screen M5. Specifically, the creation support unit 85 sets the start point of the diffusion work of the diffuser 1B in the area Q1 and sets the first traveling route R1a in the area Q1 in the predetermined field (field A). Further, the creation support unit 85 sets a second travel route R1b following the first travel route R1a in the region Q2, sets a third travel route R1c following the second travel route R1b in the region Q3, and sets the region Q4. The fourth traveling route R1d following the third traveling route R1c is set in the area, and the end point of the diffusion work of the diffuser 1B is set in the area Q4.

According to this, the traveling route R1 of the diffuser 1B is set to a place where the first moisture value is high in order from the low place. Therefore, it is possible to gain time for the diffuser 1B to reach the location where the first moisture value is high from the location where the first moisture value is low. By the time the diffuser 1B reaches the location where the first moisture value is high, the moisture in the location where the first moisture value is high can be reduced, and by devising the traveling route, the overall moisture value can be reduced. it can.

In the above-described embodiment, the creation support unit 85 creates the traveling route R1 in ascending order of the first moisture value, but in the region where the first moisture value is high, for example, the region Q4 and the like, the diffuser 1B A traveling route R1 that increases the traveling to two times may be created. In this case, the fourth traveling route R1d in the area Q4 reciprocates at least in the area Q4 and then heads for the end point.
Further, although the traveling route R1 of the diffuser 1B has been described as an example, the traveling route R1 of the weed collector 1C and the traveling route R1 of the molding machine 1D can be applied instead.

The preparation support unit 85 may support the preparation of a work plan based on the pasture information. FIG. 11 shows an example of the basic setting screen M6 for setting the work plan. When the basic setting unit 109 is selected on the creation screen, the creation support unit 85 displays the basic setting screen M6 on the display unit 84b.
On the basic setting screen M6, a pasture setting unit 120 for making settings related to pasture is displayed. The pasture setting unit 120 has a setting unit 120a for setting whether or not to reflect the pasture information in the work plan, a registration unit 120b for registering the pasture information, and a pasture display unit 120c for displaying the registered pasture information. are doing. In the setting unit 120a, ON / OFF can be selected, and when it is ON, the pasture information is reflected in the work plan, and when it is OFF, the pasture information is not reflected in the work plan. Pasture information such as a pasture name, a pasture type, and a pasture variety can be input to the registration unit 120b. When the administrator or the like uses the support device 84 to input grass information into the registration unit 120b of the basic setting screen M6, the support device 84 stores the input grass information in the storage unit 84c.

That is, the support device 84 includes a pasture information acquisition unit 88. The grass information acquisition unit 88 is composed of electrical / electronic parts provided in the support device 84, a program incorporated in the calculation unit 84a (support device 84), and the like. The pasture information acquisition unit 88 acquires the pasture information input to the registration unit 120b of the basic setting screen M6. In the above-described embodiment, the support device 84 (pasture information acquisition unit 88) has acquired the pasture information input to the registration unit 120b, but the pasture information may be acquired using an external network or the like. For example, when the basic setting screen M6 or the like is displayed, the grass information acquisition unit 88 connects the support device 84 to a server of a company or the like that provides grass information via an external network (WAN or the like), and grass information. To get.

The pasture display unit 120c displays a list of pasture names and the like among the pasture information acquired by the support device 84 (pasture information acquisition unit 88). The name of the grass displayed on the grass display unit 120c can be selected.
The creation support unit 85 extracts the pasture information corresponding to the pasture name selected in the pasture display unit 120c from the storage unit 84c, and sets the work period or the date schedule unit 105 based on the extracted pasture information. , Adjust the work time set in the time schedule unit 107. For example, depending on the type (variety) of grass, the water content, hardness, size, etc. are different, and there are varieties that are easy to dry even under the same weather conditions, and varieties that are difficult to dry. The creation support unit 85 has a correction value, etc. determined by the type (variety) of grass, etc., and adds the correction value to the standard value (work period, work time) determined for each work, or Multiply the correction value.

The creation support unit 85 may support the creation of a work plan based on the information (machine information) about the work machine. As shown in FIG. 11, on the basic setting screen M6, the machine setting unit 130 for setting the work machine is displayed. The machine setting unit 130 includes a setting unit 130a for setting whether or not to reflect the machine information in the work plan, a registration unit 130b for registering the machine information, and a machine display unit 130c for displaying the registered machine information. are doing. In the setting unit 130a, ON / OFF can be selected, and when it is ON, the machine information is reflected in the work plan, and when it is OFF, the machine information is not reflected in the work plan. Machine information such as the name, model number, model, and number of owned work machines (grass cutter, diffuser, grass collector, molding machine, etc.) can be input to the registration unit 130b. When the administrator or the like uses the support device 84 to input machine information to the registration unit 130b of the basic setting screen M6, the support device 84 stores the input machine information in the storage unit 84c.

That is, the support device 84 includes a machine information acquisition unit 89. The machine information acquisition unit 89 is composed of electrical / electronic parts provided in the support device 84, a program incorporated in the calculation unit 84a (support device 84), and the like. The machine information acquisition unit 89 acquires the machine information input to the registration unit 130b of the basic setting screen M6. The machine display unit 130c displays a list of information (machine name, model number, etc.) included in the machine information acquired by the support device 84 (machine information acquisition unit 89). The machine information displayed on the machine display unit 130c can be selected. The size and the like of all of the mowers, diffusers, grass collectors, and molding machines are different, and the processing capacity that can be processed by one machine is different. Large work machines (mowers, diffusers, grass collectors, molding machines) have high processing capacity per unit time, and small work machines (grass cutters, diffusers, grass collectors, molding machines) have units. The processing capacity per hour is low compared to the large size. Further, when the manager has a plurality of working machines of the same model (model number) in the kitchen, the processing capacity is larger than that of one working machine. The creation support unit 85 has a processing capacity value (processing capacity data) indicating the relationship between the machine information and the processing capacity, and the work period or time set in the date schedule unit 105 based on the processing capacity data. Adjust the work time set in the schedule unit 107. For example, when the processing capacity value is large, the creation support unit 85 makes the working period or working time shorter than the standard, and when the processing capacity value is small, the working period or working time is longer than the standard.

The creation support unit 85 may support the creation of a work plan based on the information regarding the shape of the field. Information about the shape of the field is, for example, the field area. The field area will be described as an example.
As shown in FIG. 11, the field setting unit 140 for setting the field is displayed on the basic setting screen M6. The field setting unit 140 has a setting unit 140a for setting whether or not to reflect the field information in the date setting or time setting in the work plan, and a registration unit 140b for registering the field information.

In the setting unit 140a, ON / OFF can be selected, and when it is ON, the field information is reflected in the date setting or time setting of the work plan, and when it is OFF, the field information is set to the date of the work plan. Or it is not reflected in the time setting. Field information such as the name, position, and area of the field can be input to the registration unit 140b. When the administrator or the like uses the support device 84 to input the field information into the registration unit 140b of the basic setting screen M6, the support device 84 stores the input field information in the storage unit 84c.

That is, the support device 84 includes a field information acquisition unit 90. The field information acquisition unit 90 is composed of electrical / electronic parts provided in the support device 84, a program incorporated in the calculation unit 84a (support device 84), and the like. The field information acquisition unit 90 acquires the field information input to the registration unit 140b of the basic setting screen M6. When the field area is vast and very large, in one predetermined field (field A), a predetermined time unit (daily unit, 6) is used by a working machine (grass cutter, diffuser, grass collector, molding machine). The processing of grass may not be completed in units of hours (12 hours). The creation support unit 85 has a standard field area (reference field area), and is set in the date schedule unit 105 based on the relationship between the field area indicated by the registered field information and the reference field area. The work period to be performed or the work time set in the time schedule unit 107 is adjusted. For example, when the field area is larger than the standard field area by a predetermined value or more, the work period or the working time is made longer than the standard, and when the field area is smaller than the standard field area by a predetermined value or more, the creation support unit 85 is used. If the working period or working time is shorter than the standard and the field area is almost the same as the standard field area, the working period or working time is not changed.

The information regarding the shape of the field is not limited to the field area, and may be the length (distance) of the field, the information indicating the shape itself, or other information. For example, when the maximum length (maximum distance) of the field is larger than the standard field distance by a predetermined value or more, the creation support unit 85 makes the working period or working time longer than the standard, and the maximum distance is larger than the standard field distance. If it is smaller than the specified value, the working period or working time is shorter than the standard, and if the field distance is almost the same as the standard field distance, the working period or working time is not changed.

By the way, in the above-described embodiment, the work plan is set based on the first moisture value at the time of cutting work, but the work plan may be set based on the moisture value at the time of diffusion work.
As shown in FIG. 1, the grass management system includes a third physical quantity detecting device 150. Similar to the first physical quantity detecting device 81, the third physical quantity detecting device 150 is a device for detecting a physical quantity related to pasture, for example, a component (water content, protein) contained in the pasture. The third physical quantity detecting device 150 is provided in the diffuser 1B. The third physical quantity detection device 150 acquires at least the water content value (referred to as the second water content value) of the grass during the diffusion work by the diffuser 1B. For convenience of explanation, when the third physical quantity detection device 150 is a device for acquiring the second moisture value of the grass during the diffusion work by the diffuser 1B, the third physical quantity detection device 150 is referred to as a "second moisture acquisition device". That is.

The second water content acquisition device 150 is provided in the diffusion unit 33, and the diffusion unit 33 acquires the second water content value of the grass when the grass is diffused. For example, the second water content acquisition device 150 is a spectroscopic analyzer that analyzes the water content of the grass by irradiating the grass with a light source having a predetermined frequency and receiving the reflected light from the grass. .. The second moisture acquisition device 150 is connected to the control device 15 or the storage device 16B provided on the tractor 2B. The second moisture acquisition device 150 transmits the acquired second moisture value to the control device 15 or the storage device 16B.

For example, when the control device 15 or the second moisture acquisition device 150 detects the start of traveling of the tractor 2B, the start of power transmission from the PTO axis to the diffusion device 3B, and the start of driving of the diffusion unit 33, the second moisture acquisition device is concerned. 150 starts the acquisition of the second moisture value. Further, when the control device 15 or the second moisture acquisition device 150 detects the end of traveling of the tractor 2B, the end of power transmission from the PTO axis to the diffusion device 3B, and the end of driving of the diffusion unit 33, the second moisture acquisition device is concerned. 150 ends the acquisition of the second moisture value. The start and end of acquisition of the second moisture value of the second moisture acquisition device 150 are not limited to the above-mentioned example, and for example, when the control device provided around the driver's seat of the tractor 2B is operated, the driver's seat This may be performed when the start or end of the diffusion work is instructed by a display device, a switch, or the like provided around the device. Alternatively, a switch or the like for instructing the second moisture acquisition device 150 to start or end acquisition of the second moisture value may be provided around the driver's seat.

Further, when the second moisture value is acquired in the diffuser 1B, at least the position (latitude, longitude) is detected by the position detection device 60B, and the detected position (diffusion position) and the second moisture value are used. Is stored in the storage device 16B.
As shown in FIG. 1, the tractor 2B includes an output device 82B. The output device 82B is a device that is connected to at least the storage device 16B and outputs the diffusion position and the second moisture value stored in the storage device 16B to the external device 83. For example, the output device 82B has a connecting portion for connecting the external device 83, and when the external device 83 is connected, the diffusion position and the second moisture value are output to the external device 83.

FIG. 12 shows a creation screen M7 when the diffusion work is completed at least once. The weekly weather forecast 102, the work item unit 103, and the date schedule unit 105 are displayed on the creation screen M7 of FIG.
When creating a work plan, the creation support unit 85 displays, for example, the moisture map 110B on the creation screen M7. As shown in FIG. 1, the water content map 110B is a map created by the water content map creation unit 87. The moisture map creating unit 87 refers to the storage unit 84c and determines whether or not the second moisture value and the diffusion position detected at the time of the diffusion operation are stored on a predetermined date. The moisture map creating unit 87 determines, for example, whether or not the second moisture value and the diffusion position detected in the diffusion operation on 5/22 are stored in the storage unit 84c. When the second moisture value and the diffusion position in the diffusion operation on 5/22 are stored in the storage unit 84c, the moisture map creation unit 87 creates a moisture map 110B in which the second moisture value and the diffusion position correspond to each other. ..

For example, in the date schedule unit 105 of the creation screen M7, when the relationship between the work and the date can be arbitrarily changed, the administrator can arbitrarily change the date of the next diffusion work by referring to the moisture map 110B, or next. The day can be changed from spreading work to weeding work. For example, when it is determined that the moisture value displayed on the moisture map 110B is lower than the predetermined value and the grass collecting work can be changed, the diffusion work on the next day is changed to the grass collecting work. On the other hand, when the moisture value displayed on the moisture map 110B is higher than a predetermined value, the working period of the diffusion work in the date schedule portion 105 can be lengthened.

In the above-described embodiment, the administrator changes the date while looking at the moisture map 110B displayed on the creation screen M7, but the creation support unit 85 works in the work plan based on the second moisture value or the moisture map 110B. The date may be set automatically. Further, the creation support unit 85 may automatically set the number of operations in the work plan based on the second moisture value or the moisture map 110B. In addition, in the operation of the creation support unit 85 to change the work date, the number of times, etc. based on the second moisture value or the moisture map 110B, the above-mentioned "first moisture value" is read as "second moisture value" and "moisture". "Map 110A" may be read as "moisture map 110B".

Further, by changing the date schedule unit 105 of the creation screen M7 to the time schedule unit 107, the work time can be changed based on the second moisture value or the moisture map 110B. In addition, in the operation of the creation support unit 85 to change the work time or the like based on the second moisture value or the moisture map 110B, the above-mentioned "first moisture value" is read as "second moisture value" and "moisture map 110A". Should be read as "moisture map 110B".

Further, the change of the work plan in the second moisture value can also be applied to the change of the work plan of the weed collector 1C and the molding machine 1D other than the diffuser 1B. In this case, the diffuser 1B may be read as "grass collector 1C" or "molding machine 1D", and the diffusion work may be read as "grass collecting work" or "molding work". Further, based on the first moisture value or the moisture map, the work plan in the work (diffusion work, weed collection work, molding work) performed after the cutting work may be changed in a complex manner.

Further, in the above-described embodiment, the date, time, number of times, and work plan of the traveling route are adjusted (set) based on the first moisture value or the moisture map, but when there are a plurality of working machines, the work plan is adjusted (set). The order of work on each work machine may be adjusted (set). For example, as shown in FIG. 10, the first diffuser 1B performs the diffusion work along the traveling route defined by the moisture map (first moisture value), while the second diffuser 1B is used. In the region Q4 where the first moisture value is high, the diffusion work may be performed separately from the first diffuser 1B.

Further, for example, when the manager or the like owns the mower 1A and the diffuser 1B and works on the same date or working time, the mower 1A is performing the mowing work in the field A. , "In the field B, the mowing work cannot be performed by the mower 1A, while the diffusing work can be performed by the diffusing machine 1B", the creation support unit 85 may display on the creation screen. When the number of traveling vehicles and the number of devices (cutting device 3A, diffusion device 3B, weed collecting device 3C, molding device 3D) attached to the traveling vehicle are different, the creation support unit 85 determines the number of traveling vehicles. , Work planning may be supported based on the relationship with the number of devices mounted on the traveling vehicle. For example, when there are two devices for one traveling vehicle (for example, one cutting device 3A and one spreading device 3B), diffusion is performed during the cutting operation by the cutting device 3A in the field A. The creation support unit 85 displays on the creation screen that the diffusion work in the device 3B cannot be performed.

Further, in the above-described embodiment, the first moisture value and the cutting position are the values when the work machine performed the work one time before, but the past actual values may be used. For example, when working on the same field, the first moisture value and the cutting position (actual information) acquired during the cutting work several months ago, one year ago, etc. from the present are used for the later working machine (actual information). The work plan of the diffuser 1B, the weed collector 1C, and the molding machine 1D) may be adjusted.

By the way, the first physical quantity detection device 81 can detect the height (plant height) of the grass growing in the field as the physical quantity (first physical quantity information) related to the grass. The first physical quantity detection device 81 detects the grass height during the mowing operation by the mower 1A. For convenience of explanation, the height of grass (plant height) is called the plant height value.
The first physical quantity detecting device 81 is provided on the tractor 2A or the cutting section 23, and detects the plant height value of the grass extending from the field immediately before cutting. The grass information acquired during the cutting operation is transmitted to the control device 15 or the storage device 16A and stored in the storage device 16A. Since the start and end of the acquisition of the plant height value in the first physical quantity detecting device 81 are the same as the timing of detecting the first water content value as described above, the description thereof will be omitted.

Further, when the acquisition of the plant height value is executed in the mower 1A, the mowing position (first machine position), which is the position at the time of mowing work, is detected by the position detection device (first position detection device) 60A. As shown in 13, the cutting position and the plant height value are stored in the storage device 16A.
As shown in FIG. 1, the grass management system includes a second physical quantity detection device 151. The second physical quantity detection device 151 is a device capable of detecting the weight (yield) of grass as a physical quantity (second physical quantity information) related to grass. The second physical quantity detecting device 151 is provided in the molding machine 1D. The second physical quantity detecting device 151 acquires the weight (yield) of the grass during the molding operation by the molding machine 1D. The second physical quantity detecting device 151 is a load cell or the like capable of detecting the weight, and is provided in the molding section 57 or the discharging section 58. The second physical quantity detection device 151 measures the weight of the molding material discharged from the discharge unit 58 to the field as the weight of the grass. For example, the second physical quantity detecting device 151 detects the weight of the molded material, that is, the yield of grass, when the molding machine 1D discharges the molded material molded by the molding unit 57 to the field. The second physical quantity detection device 151 is connected to the control device 15 or the storage device 16D provided on the tractor 2D. The second physical quantity detection device 151 transmits the acquired weight (yield) of the molded material to the control device 15 or the storage device 16D.

Further, when the yield of grass is acquired in the molding machine 1D, the molding position (second machine position), which is the position at the time of molding work, is detected by the position detecting device (second position detecting device) 60D. As shown in FIG. 14, the molding position and the yield are stored in the storage device 16D. In the molding machine 1D, the weight (yield) of the molded material is detected when the molded material is discharged. Therefore, the molding position corresponding to the weight (yield) of the molded material indicates the discharge position of the molded material. There is.

As shown in FIG. 1, the tractor 2D includes an output device 82D. The output device 82D is a device that is connected to at least the storage device 16D and outputs the molding position including the discharge position stored in the storage device 16D and the yield to the external device 83. The output device 82D has a connecting portion for connecting the external device 83, and when the external device 83 is connected, the output device 82D outputs the molding position including the discharge position and the yield to the external device 83.

The support device 84 includes a database. In this embodiment, the database is the same as the storage unit 84c. The above-mentioned storage unit 84a and the database may be configured separately. The storage unit 84c stores the first physical quantity information (plant height value) of the grass, the first machine position (cutting position), the second physical quantity information (yield) of the grass, and the second machine position (molding position). For example, when an external device 83 that stores the mowing position and the plant height value is connected to the support device 84 after the mowing operation by the mower 1A, the mowing position and the plant height value stored in the external device 83 are transferred to the storage unit 84a. Will be done. Further, when the external device 83 that stores the molding position including the discharge position and the yield is connected to the support device 84 after the molding operation by the molding machine 1D, the molding position and the plant height including the discharge position stored in the external device 83 are connected. The value is transferred to the storage unit 84c. Therefore, the storage unit 84c can store the plant height and the cutting position at the time of the cutting work, and the yield and the molding position at the time of the molding work. The plant height and cutting position at the time of cutting work and the yield and molding position at the time of molding work stored in the storage unit 84c can be displayed on the display unit (display device) 84b.

The storage unit 84a may store the plant height and the cutting position acquired at the time of the cutting work at each time of the cutting work. In addition, the storage unit 84a may store the yield and the molding position acquired during the molding operation for each molding operation. That is, the storage unit 84a stores the plant height, the cutting position, the yield, and the molding position, for example, every few months or every year.
According to the above, the plant height at the time of cutting work and the yield at the time of molding work can be stored in the database. Therefore, since the relationship between the plant height and the yield can be grasped, this relationship can be reflected in the work such as fertilization.

4 levels) are set, and the plant height values corresponding to each level are mapped and displayed on the first display unit 171.

For example, the first map creation unit 161 divides a predetermined field (field A) into a plurality of predetermined areas A2, obtains an average plant height value for each predetermined area A2, and assigns each level to the average plant height value. .. In the first map creation unit 161, the level with the lowest average plant height is "level 1", the level with the highest average plant height is "level 4", and the level with the highest average plant height next to "level 1" is "level". The level with the highest average plant height next to "2" and "level 2" is set to "level 3", and the level with the next highest average plant height after "level 3" is set to "level 4". The first map creation unit 161 creates the first physical quantity map 163 by dividing levels 1 to 4 according to numbers, figures, characters, colors, and the like.

The method of creating the above is not limited to the method described above.
The second map creation unit 162 refers to the storage unit 84c and extracts the yield and the cutting position corresponding to the date and the field set by the setting unit 173. The second map creation unit 162 creates a second physical quantity map 164 in which the yield and the molding position correspond to each other. In creating the second physical quantity map 164, the second map creation unit 162 sets in advance the levels indicating the high and low yields in several stages (for example, four stages), and maps the yield values corresponding to each level. It is displayed on the second display unit 172.

For example, the second map creation unit 162 divides a predetermined field (field A) into a plurality of predetermined areas A2, and obtains an average yield value (average value per unit area in the predetermined area A2) for each predetermined area A2. , Assign each level to the average yield. Specifically, as shown in FIG. 16, after discharging the previous molding material F1, the collection area S1 is obtained from the moving distance L1 to the next molding material F2 and the weeding width W1 by the weed collector 1C, and the molding material F2 The average yield per unit area is obtained by dividing the weight (yield) of The method for calculating the average yield value is an example, and is not limited to this.

Then, the second map creation unit 162 sets the level with the lowest average yield value as "level 1", the level with the highest average yield value as "level 4", and the level with the highest average yield value next to "level 1". The level with the highest average yield value next to "level 2" and "level 2" is set to "level 3", and the level with the next highest average yield value after "level 3" is set to "level 4". The second map creation unit 162 creates the second physical quantity map 164 by dividing the levels 1 to 4 according to numbers, figures, characters, colors, and the like. The second map creation unit 162 may represent the yield value itself as a map, and the method of creating the second physical quantity map 164 by the second map creation unit 162 is not limited to the above-mentioned method. Further, in the field screen M10 described above, the map corresponding to the date is displayed by specifying the date, but the map corresponding to the time may be displayed by specifying the time (time).

(Range RW1), when the plant height and the yield are substantially the same (range RW2), when the plant height is low but the yield is high (range RW3), and the like can be grasped. That is, it is possible to grasp the relationship between the distribution of grass height in the field and the density (whether or not the grass is dense). Note that FIG. 15 shows an example of three patterns (RW1, RW2, RW3) at the same time for a predetermined field (field A) for convenience of explanation, and the range, numerical values, and the like are not limited.

As shown in FIG. 1, the pasture management system includes a terrain information acquisition device. The terrain information acquisition device is a device that acquires terrain information of a field. The terrain information acquisition device acquires the height information of the field detected during the mowing operation by the mower 1A as terrain information. Specifically, the terrain information acquisition device is a position detection device 60A provided in the mower 1A. As described above, the position detection device 60A determines not only the position (latitude, longitude) but also the height (height information) in the vertical direction (height direction) based on the signal transmitted from the positioning satellite during the mowing operation.

As shown in FIG. 1, the grass management system includes an emission information acquisition unit 200 and a route creation unit 210. The discharge information acquisition unit 200 and the route creation unit 210 are provided in the support device 84. That is, the emission information acquisition unit 200 and the route creation unit 210 are composed of electrical / electronic parts provided in the support device 84, a program incorporated in the calculation unit 84a (support device 84), and the like.

The discharge information acquisition unit 200 acquires the planned discharge position H1 for discharging the molded material molded by the molding machine 1D to the field. The route creation unit 210 creates a travel route R2 of the grass collector 1C that collects the grass before the work in the molding machine 1D based on the topographical information and the planned discharge position H1.
FIG. 17 shows a setting screen M11 for setting the traveling route R2 displayed on the display unit 84b.

When the administrator or the like operates the support device 84, the route creation unit 210 causes the display unit 84b of the support device 84 to display the setting screen M11. The setting screen M11 has a setting unit 215 for setting the field, a terrain display unit 216 for displaying the terrain (terrain map) 220 of the field, and a route display unit 217 for displaying the traveling route.
When the field is set in the setting unit 173, the route creating unit 210 refers to the storage unit 84c and extracts the terrain information corresponding to the field set by the setting unit 215. When there are a plurality of topographical information in the same field, the route creation unit 210 extracts the latest topographical information with a new date. When a plurality of terrain information in the same field exists, the route creation unit 210 displays a list of the time or date when the terrain information was acquired on the setting screen M11, and extracts the terrain information selected in the list. You may try to do it.

The route creation unit 210 displays the three-dimensional terrain map 220 on the terrain display unit 216 based on the extracted terrain information. In the above-described embodiment, the terrain map 220 is created based on one terrain information in the same field, but the terrain map 220 may be created using a plurality of terrain information in the same field. When the route creation unit 210 creates the terrain map 220, the route creation unit 210 displays it on the terrain display unit 216.

On the field of the terrain display unit 216, that is, the field showing the terrain map 220, the planned discharge position H1 of the molding material in the molding machine 1D can be set. For example, when the administrator uses the input interface (mouse, keyboard, etc.) of the support device 84 to select the route creation unit (discharge position setting unit) 210 on the field of the terrain map 220, the position of the selected field is formed. Set to the planned discharge position H1 of the material. That is, the discharge information acquisition unit 200 recognizes the position (latitude, longitude) at the selected time on the field of the terrain map 220 as the planned discharge position H1 and acquires the planned discharge position H1 at the selected time. Therefore, the emission information acquisition unit 200 acquires a plurality of planned emission positions H1 each time the field on the terrain map 220 is selected. The route creation unit 200 and the discharge position setting unit may be configured separately.

In the above-described embodiment, each time the emission information acquisition unit 200 selects a plurality of planned emission positions H1 on the field of the terrain map 220, a plurality of planned emission positions H1 are acquired, but a predetermined range on the field of the terrain map 220 is input by an input interface or the like. When selected, a position included in the predetermined range may be acquired as the planned discharge position H1.
In addition, in setting the planned discharge position H1, it may be determined whether or not the molded material can be properly discharged. That is, as shown in FIG. 1, the grass management system may include a discharge position determination unit 230. The discharge position determination unit 230 is composed of electrical / electronic parts provided in the support device 84, a program incorporated in the calculation unit 84a (support device 84), and the like.

The discharge position determination unit 230 determines from the topographical information whether the planned discharge position H1 can be set. For example, the discharge position determination unit 230 determines from the terrain information whether or not the periphery at the planned discharge position H1 or the planned discharge position H1 selected on the field of the terrain map 220 is not inclined. The discharge position determination unit 230 determines that the planned discharge position H1 cannot be set when the periphery of the planned discharge position H1 has a downward slope or an upward slope, and is not suitable as the planned discharge position H1 on the setting screen M11. A warning indicating that is displayed on the setting screen M11. For example, when the slope 220b is selected as the planned discharge position, the discharge position determination unit 230 determines that the slope 220b is unsuitable and displays a warning on the setting screen M11.

On the other hand, the discharge position determination unit 230 determines that the planned discharge position H1 can be set when the periphery of the planned discharge position H1 is flat, and displays a figure or the like indicating the planned discharge position H1 on the setting screen M11. Holds the planned discharge position H1. For example, when the planned discharge position H1 is set on the flat ground 220a of the terrain map 220, the discharge position determination unit 230 determines that the planned discharge position H1 can be set and holds the planned discharge position H1. The discharge position determination unit 230 has a very slight inclination even when the periphery of the planned discharge position H1 has a downward slope or an upward slope, and when the molded material after discharge does not roll from the planned discharge position H1, the discharge position determination unit 230 has a very slight inclination. It is determined that the planned discharge position H1 can be set.

The route creation unit 210 creates the travel route R2 of the grass collector 1C after the setting of the planned discharge position H1 is completed. As shown in FIG. 17, for example, the description will proceed assuming that the planned discharge position H1 is set on the flat land 220a of the terrain map 220.
The route creation unit 210 sets the travel route R2 of the grass collector 1C along the slope direction of the slope 220b. In other words, in the terrain map 220, when the front side is a flat land 220a and the back side is a slope 220b, and the altitude of the terrain map 220 increases from the front to the back, the route creation unit 210 collects. The traveling route R2 of the grass machine 1C is set from the front to the back. Assuming that the traveling route R2 of the weed collector 1C and the traveling route of the molding machine 1D match, the route creating unit 210 makes the discharge position of the molding material in the molding machine 1D substantially located at the planned discharge position H1. The traveling route R2 of the grass collector 1C is set. For example, as shown in FIG. 17, when the route creation unit 210 pays attention to the two planned discharge positions H1a and H1b adjacent to the flat portion 220b, the traveling route R2 of the grass collector 1C is set to one of the planned discharge positions H1a. After moving away from the slope 220b and heading to the slope 220b, the locus is set to return to the other scheduled discharge position H1b by turning back at the slope 220b. In the traveling route R2 of the grass collector 1C, the interval L2 of the adjacent traveling routes R2 is set by a preset grass collecting width W1 or the like of the grass collector 1C.

When the travel route R2 is created, the route creation unit 210 displays, for example, the travel route R2 represented in two dimensions (X-axis, Y-axis) on the route display unit 217. After creating the travel route R2, the route creation unit 210 may display the travel route R2 represented in three dimensions (X-axis, Y-axis, Z-axis) on the route display unit 217.
The route creation unit 210 may create the traveling route R2 based on the information about the grass collector 1C, that is, the machine information of the grass collector 1C. As shown in FIG. 18, the grass collector 1C (grass collector 3C) is a first type 1CA that collects grass in the center of the grass collector 1C in the width direction by two grass collecting portions 43, and one grass collecting unit. Second type 1CB that collects grass on one side in the width direction of the grass collector 1C by the part 43, and grass is collected in the central part of the width direction of the grass collector 1C by the two grass collecting parts 43 and one side in the width direction. There is a third type 1CC that collects grass in. The width (grass collection width) W1 for collecting grass is also different between the first type 1CA, the second type 1CB, and the third type 1CC.

When the route creation unit 210 selects the machine information unit 211 displayed on the setting screen M11, the machine information acquisition unit 89 acquires the machine information of the grass collector 1C and stores it in the support device 84. Is displayed on the display unit 35c. The list of grass collectors 1C displayed on the display unit 35c can be selected. When the machine information corresponding to the first type 1CA is selected, the route creation unit 210 sets the grass collection width W1A of the first type 1CA to the width at the time of creating the traveling route R2. When the machine information corresponding to the second type 1CB is selected, the route creation unit 210 sets the grass collection width W1B of the second type 1CB to the width at the time of creating the traveling route R2. When the machine information corresponding to the third type 1CC is selected, the route creation unit 210 sets the grass collection width W1C of the third type 1CC to the width at the time of creating the traveling route R2.

In the above-described embodiment, the traveling route is set based on the topographical information and the planned discharge position, but the traveling route may be set based on the height (plant height) of the grass and the planned discharge position. As shown in FIG. 1, the pasture management system includes a pasture height acquisition device. In this embodiment, the grass height acquisition device is the first physical quantity detection device 81 provided in the mower 1A. The grass height acquisition device and the first physical quantity detection device 81 may be provided separately.

FIG. 19 shows a setting screen M12 for setting the traveling route R2 displayed on the display unit 84b.
When the administrator or the like operates the support device 84, the route creation unit 210 causes the display unit 84b of the support device 84 to display the setting screen M12. The setting screen M12 has a setting unit 215 for setting the date and the field, and a route display unit 217 for displaying the plant height map of the grass height (plant height) and the traveling route.

The planned discharge position H1 can be set in the route display unit 217. The planned discharge position H1 can be set by selecting the field of the route display unit 217 in the same manner as the setting screen M11.
The route creation unit 210 refers to the storage unit 84c and extracts the plant height and the cutting position corresponding to the date and the field. The route creation unit 210 divides the plant height map 240 in which the plant height and the cutting position correspond to each other, and the route creation unit 210 divides, for example, a predetermined field (field A) into a plurality of predetermined areas A2, and determines the plant height value for each predetermined area A2. A plant height map 240 is created by obtaining a total (plant height amount) and assigning the plant height amount to each predetermined area A2 by numbers, figures, letters, colors, and the like. The creation of the plant height map 240 described above is an example and is not limited.

On the field of the traveling route display unit 217, that is, the field showing the plant height map 240, the planned discharge position H1 of the molding material in the molding machine 1D can be set by the same method as described above.
The route creation unit 210 creates the travel route R2 of the grass collector 1C after the setting of the planned discharge position H1 is completed. The route creation unit 210 sets the amount of plant height in the predetermined area A2 as the yield in the predetermined area A2. Then, the route creation unit 210 sets a point where the total yield (plant height) of the plurality of predetermined areas A2 matches the weight (discharge weight) of the molding material discharged from the molding machine 1D as a discharge candidate position. , The traveling route R2 is created so that the discharge candidate position and the planned discharge position H1 coincide with each other. For example, when the discharge weight of the molded material is 500 kg, the route creation unit 210 sets the discharge candidate position as the discharge candidate position when the total yield (plant height) of the plurality of predetermined areas A2 and the total yield matches 500 kg. A travel route R2 whose candidate position coincides with the planned discharge position H1 is obtained. In the above-described embodiment, the total plant height value (plant height amount)
However, the relationship between the plant height value and the yield may be converted into data in advance, a conversion formula showing the relationship between the plant height value and the yield may be obtained from the data, and the traveling route R2 may be obtained using the conversion formula. However, it may be obtained by other methods.
