For example, when the shift lever 35 is operated, the gear ratio of the hydraulic continuously variable transmission 16 is switched according to the operation amount, and the output from the hydraulic continuously variable transmission 16 is changed. Further, the sub-shift lever 38 can be switched to “working speed” or “road speed”, and the gear position of the sub-transmission mechanism in the mission case 18 is the operation position of the sub-shift lever 38. It is switched by.

  In addition, when the seedling transplanter 2 performs the planting operation in the field, the GPS control device 120 acquires the position information of the seedling transplanter 2 and steers with the automatic steering device 110, so that the planting operation is performed while moving straight ahead. It is possible to do. Specifically, the seedling transplanter 2 receives a signal from an artificial satellite used in GPS by the receiving antenna 121 of the GPS control device 120, thereby obtaining position information of the seedling transplanter 2 on the earth at a predetermined time interval. Get every.

  The tablet terminal device 140 stores information on a straight traveling path that is a traveling path for efficiently performing planting work in a farm field, and the controller 200 stores information on the straight traveling path stored in the tablet terminal device 140, The position information acquired by the receiving antenna 121 is compared, and the automatic steering device 110 is controlled.

  The control of the automatic steering device 110 is performed by detecting the steering angle with the handle potentiometer 112 so that the position information acquired by the receiving antenna 121 is along the information on the straight traveling path stored in the tablet terminal device 140. Steering is performed by operating the steering motor 111 while detecting a change in the traveling direction. Thereby, the traveling vehicle body 3 is caused to travel while being assisted along the straight traveling path stored in the tablet terminal device 140.

  When the seedling transplanter 2 is run or works as described above, the tablet terminal device 140 stores work information in the tablet terminal device 140. In this tablet terminal device 140, map data of a farm field to be operated can be stored and displayed on the touch panel 141, and information for each place can be obtained based on previous work information or manually input data. Can be displayed separately on the map. Thereby, in the tablet terminal device 140, based on the stored work information, a work plan for work to be performed can be performed. In the work plan, the field and date for the work, the content of the work, and the amount of work materials such as seedlings and fertilizer to be used are decided.

  Specifically, for the work information, the tablet terminal device 140 stores the work information of the seedling transplanter 2 that performs the work by communicating with the seedling transplanter 2 while being placed on the seedling transplanter 2. Is possible. This work information relates to, for example, work day, travel distance, work time, fuel consumption, planting work in the seedling planting unit 50, fertilization work in the fertilizer application 70, and supply of medicine in the medicine supply apparatus 101. Information and the like are stored. That is, in the tablet terminal device 140, not only the information regarding the operation state of the working device but also the set values such as the seedling planting interval and the planting depth when the seedling planting unit 50 performs the planting operation, and the fertilizer application device 70 applies fertilizer. Information about the setting of the working device, such as the amount of fertilizer applied when performing work, is also stored.

Obtained by the tablet terminal device 140. Thus, the tablet terminal device 140 which acquired the work information of the seedling transplanter 2 stores the work information in the storage unit 143.

  As described above, when the work information is stored in the tablet terminal device 140, the position information when the work is performed is also stored. This position information is acquired by the GPS control device 120. Specifically, the GPS control device 120 acquires the position information of the seedling transplanter 2 on the earth at predetermined time intervals by receiving a signal from an artificial satellite used in GPS by the receiving antenna 121. At that time, the GPS control device 120 appropriately expands / contracts the expansion / contraction cylinder 127 according to the control signal from the controller 200, so that the direction of the reception antenna 121 is set to be easy to receive the signal from the artificial satellite. When transmitting the work information to the tablet terminal device 140, the controller 200 transmits the position information acquired by the reception antenna 121 in this manner in association with the work information. Thereby, the tablet terminal device 140 stores the work information for each work position when the work information is stored in the storage unit 143.

  The tablet terminal device 140 transmits the stored work information and position information to the server 155. That is, the tablet terminal device 140 transmits the work information and position information stored in the storage unit 143 to the server communication unit 157 by the terminal communication unit 144. The server 155 that has acquired the work information and position information of the seedling transplanter 2 by transmission from the tablet terminal device 140 stores the acquired work information and the like in the storage unit 156.

  Based on the past work information stored as described above, the tablet terminal device 140 performs a work plan for work to be performed in the future. In this work plan, not only the work information of the seedling transplanter 2 but also information related to seedlings, fertilizers and the like used when working in the field is used. For this reason, the tablet terminal device 140 also stores information related to seedlings, fertilizers, and the like when working in the field 250 in the past.

  The tablet terminal device 140 includes, for example, information on the types of crops such as rice and vegetables cultivated in the field 250, information on the types of fertilizers and drugs used for cultivation of the crops, and information on the crop yield. This is stored by storing in the storage unit 143. The information is input to the tablet terminal device 140 by the operator by performing an input operation on the touch panel 141 before or after the operation on the farm field 250 and is stored in the tablet terminal device 140.

  Information stored in the tablet terminal device 140 as described above is transmitted to the server 155 and is also stored in the storage unit 156 of the server 155. Thereby, it is possible to store the data in the server 155 regardless of the storage capacity of the tablet terminal device 140. In addition, when the tablet terminal device 140 is used to work on another work device, the tablet terminal device 140 By extracting information about the work device from the server 155, a work plan when working with the work device can be performed.

  When the work plan is performed on the tablet terminal device 140, the work plan for the information desired by the worker is performed by an input operation to the tablet terminal device 140. Specifically, the worker can input any one of information on the types of crops, fertilizers, and medicines, information on the crop yield, and information on setting of the work device to the touch panel 141 included in the tablet terminal device 140. Select by input operation. After selecting the information, the tablet terminal device 140 creates a work plan based on the information selected by the worker and the information stored in the storage unit 143. In this work plan, the optimum cultivation start time of the crop at that time, the timing of mid-cultivation work such as topdressing and water volume management, the harvest start timing of the crop, the type and amount of fertilizers and drugs used for cultivation of the crop A work plan including at least one of the above is created. By performing work based on the work plan created in this way, the worker can perform appropriate work regardless of the type of crop, the type of fertilizer, and the like. For example, data on the amount of harvest for each planting strain and each planting depth is accumulated for each type of crop, and when a new operation is performed on the field 250, fine adjustment between the plants is performed with reference to this data.

  Further, the tablet terminal device 140 and the server 155 also store the weather information of the work place when the work device such as the seedling planting unit 50, the fertilizer application device 70, and the medicine spraying device 90 is used. For example, a weather forecast for the next several days in the area where the tablet terminal device 140 is located is acquired via the Internet or the like and stored in the storage unit 143. For this reason, when the work plan is made, the work plan is corrected based on the weather information. For example, when it is predicted that bad weather will occur in the future, correction is made so that an arbitrary work is completed early, or correction is performed so that the work is performed after the weather recovers.

  In addition, depending on the work place such as the agricultural field 250, there are places where water use conditions such as water available time are defined. As described above, the tablet terminal device 140 and the server 155 also store such a water condition, and corrects the work plan based on the stored water condition when performing the work plan. The irrigation conditions are stored in the tablet terminal device 140 or the server 155 when an operator performs an input operation on the tablet terminal device 140.

  Further, the water amount adjustment control device 265 calculates the water amount of the farm field 250 based on the detection values of the first water amount sensor 253 and the second water amount sensor 258, and the water amount adjustment control device 265 calculates the water amount thus calculated. The amount of water is transmitted to the server 155 every predetermined time. The server 155 transmits information regarding the amount of water sent from the water amount adjustment control device 265 to the tablet terminal device 140, and the tablet terminal device 140 corrects the work plan based on the information regarding the amount of water in the field 250.

  In addition, the tablet terminal device 140 transmits a control signal to the water amount adjustment control device 265 as necessary, and operates the first motor 252 and the second motor 257 via the water amount adjustment control device 265, thereby Adjust the water volume of 250. For example, the amount of water suitable for rice cultivation varies depending on the rice varieties, planting stocks set, and planting depth, so information on water management for each rice varieties and planting work settings The database is stored in the tablet terminal device 140 or the server 155, and used as information for work planning. The 1st motor 252 and the 2nd motor 257 adjust the amount of water of the farm field 250 by operating based on the information about this water management.

  The amount of water in the field 250 is not controlled by transmitting a control signal from the tablet terminal device 140 to the water amount adjustment control device 265, but the target value of the opening of the intake gate 251 and the drainage gate 256 is set. Adjustment may be performed by manually performing an input operation on the water amount adjustment control device 265 according to the target value displayed on the touch panel 141 of the tablet terminal device 140.

  Further, the tablet terminal device 140 determines the amount of fertilization necessary for work on the field 250, the amount of medicine necessary for work on the field 250, and the supply timing of the medicine based on the information selected by the worker at the time of work planning. And displayed on the touch panel 141. Thereby, since the operator can recognize the fertilization amount, the amount of the medicine, and the supply timing of the medicine, the fertilizer and the medicine are prepared according to this, and the fertilizer is put into the storage hopper 71 or the medicine hopper 100 is put into the medicine hopper 100. It becomes possible to prepare by putting drugs.

  When working along the work plan, the tablet terminal device 140 works while communicating with the seedling transplanter communication unit 201 of the seedling transplanter 2, and the tablet terminal device 140 follows the work plan. Then, the work device is operated via the controller 200. Thereby, the fertilizer application amount adjustment motor 86 of the fertilizer application 70 is operated by the operation of the tablet terminal device 140, and the fertilizer application device 70 performs fertilization work with the fertilizer application amount derived by the work plan. Similarly, the solenoid 103 of the medicine supply device 101 is activated by the operation of the tablet terminal device 140, and the medicine spraying device 90 sprays the medicine at the amount and supply timing of the medicine derived by the work plan.

  For example, when the amount of fertilizer is too much or too small, crushed rice, which is a rice that cannot be used for food, may be generated because the rice is too small or cracked. For this reason, waste rice is judged when milling rice, the waste rice rate which is the ratio of the waste rice to the harvest is calculated, and the tendency of the amount of fertilizer when this rice is cultivated is judged. These pieces of information are stored in the tablet terminal device 140 or the server 155 and used as information when performing a work plan. When working according to the work plan, the fertilization amount adjusting motor 86 is operated so that the fertilization amount in consideration of the waste rice rate at the time of the previous work in the field 250 is performed, and the fertilization work is performed.

  In addition, since the amount of fertilizer and the amount of topdressing varies depending on the variety of rice, information on the amount of fertilizer and the amount of topdressing for each variety is stored as a database in the tablet terminal device 140 and the server 155 as information when performing a work plan. Use. In addition, since fertilizer amount and fertilizer amount differ depending on the brand of fertilizer, information on fertilizer amount and fertilizer amount for each brand is made into a database and stored in the tablet terminal device 140 and server 155 as information when performing work plans Use.

  In addition, as information on the fertilizer, an optimal amount of top fertilization, time, brand, etc. are also stored in a database and used as information when performing a work plan. At that time, the optimum top fertilizer amount, time, and brand are stored for each planting stock and for each planting depth. As a result, when performing fertilization work, it is possible to perform fertilization work with an appropriate amount of fertilizer for each rice variety and brand of fertilizer, and the optimum fertilization according to the setting state of planting work Work can be done.

  In addition, if the amount of the medicine is wrong, the seedling may die, so the information on the medicine to be used is stored in the tablet terminal device 140 or the server 155 and stored in the tablet terminal device 140 or the server 155 for the work plan. Used as information when performing. In the case of working according to the work plan, the solenoid 103 of the medicine supply device 101 is operated in this manner to spray the medicine.

  In addition, since the amount of medicine sprayed and the type of medicine differ for each rice variety, information on the amount and kind of the medicine for each variety is stored as a database in the tablet terminal device 140 and the server 155, and the work plan is used. Use as information. In addition, the amount of harvest, harvest time, fertilization amount, and the spraying time and spraying amount of other drugs are different for each type of drug, so information on harvesting by type of drug, information on fertilization amount, and spraying of other drugs Is stored in the tablet terminal device 140 or the server 155 and used as information when performing a work plan.

[Modification]
In the agricultural work support system 1 according to the embodiment, the seedling transplanter 2 is used as a work vehicle. However, the work vehicle may be other than the seedling transplanter 2. The work vehicle may use, for example, a tractor that performs work on a farm field by connecting a work device to the traveling vehicle body.

  When the tractor is used as a work vehicle, for example, the travel route during the scraping work is acquired by GPS or a gyro sensor and stored in the tablet terminal device 140 or the server 155, and the travel route is extremely oblique on the farm field 250. For a portion where there is data that becomes large or meandering, the hydraulic pressure sensitivity when the angle of the float 47 of the seedling transplanter 2 changes may be changed. That is, where the travel route is likely to be disturbed, there is a high possibility that the gradient of the farm field 250 is unstable or the soil is soft and easy to sink. Therefore, in such a portion, the sensitivity of the float 47 is dulled. Thereby, it can prevent that the seedling planting part 50 does not raise / lower more than necessary.

  FIG. 11 is an explanatory diagram of a case where the travel route changes during scraping using a tractor. For example, when the GPS acquisition coordinates or the position where the traveling direction detected by the gyro sensor is greatly deviated from the straight line is set as the recording area K1, K2,... As described above, the sensitivity of the float 47 is changed. The sensitivity of the float 47 at this time may be automatic control, but when using a working machine that does not incorporate automatic control, a notification device such as a buzzer or a lamp is activated to prompt the operator to adjust the sensitivity. To do.

  FIG. 12 is an explanatory diagram of a case where the engine load changes during scraping using a tractor. Further, when the tractor is used as a work vehicle, the engine load is monitored, the soil quality of the field 250 is determined based on the engine load, the data regarding the determined soil quality is averaged for one field 250, and the tablet terminal device 140 is used. Or may be stored in the server 155. The tablet terminal device 140 notifies the worker who performs the work using the seedling transplanter 2 of information about the soil quality of the farm field 250 by displaying the soil-related data on the touch panel 141 as a map. In this case, based on the numerical value of the engine load acquired for each GPS coordinate, whether the load is higher or lower than the standard is displayed with a symbol or a color difference. For example, as shown in FIG. 12, engine load increasing points E1 and E2, engine load decreasing points D1 and D2, and engine load standard points are displayed with different symbols. Thereby, the worker can perform work according to soil quality. In FIG. 12, engine load increasing points E1 and E2 are indicated by stars, and engine load decreasing points D1 and D2 are indicated by squares.

  FIG. 13 is an explanatory diagram of a case where an overlapping section or a non-scraping section is extracted during scraping using a tractor. Further, when the tractor is used as a work vehicle, it is determined that an end of the farm field 250 is turned and reciprocated during the scraping work, and the contour is extracted. From this outline and all the travel routes in the field 250, it is determined whether there is an overlapping place or a place where you forgot to work, and the overlapping place or a place where you forgot to work is color-coded on the map, You may display on the touchscreen 141. For example, as shown in FIG. 13, based on the horizontal width of the hello that is the working device for scraping, the scraping route is color-coded and displayed on the map from the GPS coordinate information. At this time, a portion where adjacent scraping positions overlap is changed in color and displayed as overlapping sections O1, O2,. Further, a portion where there is a gap between adjacent scraping positions is white, and is displayed as non-scraping sections V1, V2,. As a result, when there is an overlap or missing part of the scraping, it is possible to determine how to proceed with the work in the next and subsequent work. Can be made uniform. The work vehicle may use a machine other than the seedling transplanter 2 as described above, and work information on the farm field 250 may be shared by a plurality of work vehicles.

  Further, in the above-described embodiment, Bluetooth is used as the short-range wireless connection for performing communication between the traveling vehicle body 3 side and the tablet terminal device 140 side, but the short-range wireless connection is performed using something other than Bluetooth. Also good. As long as the tablet terminal device 140 can wirelessly communicate with the desired traveling vehicle body 3 and the working device, the method, the format, the standard, and the like are not limited.

  Moreover, although embodiment mentioned above demonstrated using the tablet terminal device 140 as an example of an information terminal, information terminals other than the tablet terminal device 140 may be sufficient. The information terminal may be in any form as long as the information terminal is configured to be able to transmit and receive information to and from the traveling vehicle body 3, the work device, and the server 155 and can store work information.
