  Embodiments of the present invention will be described with reference to the drawings. The farm work management system of this embodiment is employed in a tractor 1 as an example of an agricultural machine. The tractor 1 is a tractor capable of shifting at eight speeds of main shift and three speeds of sub-shift, and 24 speeds. FIG. 1 shows a side view of the tractor 1 and FIG. 2 shows a power transmission mechanism.

  The tractor 1 has front wheels 2 and 2 for steering and rear wheels 3 and 3 as propulsion wheels, and the rotational power of the engine 5 mounted in the bonnet 4 is appropriately decelerated by a transmission in the transmission case 6. The rotational power is transmitted to the rear wheels 3 and 3. The rotational power of the engine 5 may be transmitted not only to the rear wheels 3 and 3 but also to the front wheels 2 and 2 to drive all four wheels.

  Further, in the mission case 6, a forward / reverse switching device 9 for switching the traveling direction of the airframe, a main transmission 10 and 11 capable of shifting in eight steps, and an auxiliary transmission 12 capable of shifting in three steps are connected in series. ing.

  In FIG. 1, a hydraulic cylinder case 14 is provided at an upper portion of the transmission case 6, and lift arms 15, 15 are pivotally attached to left and right sides of the hydraulic cylinder case 14. Lift rods 17, 17 are connected between the lift arms 15, 15 and the lower links 16, 16, and a rotary tiller 18, which is a work machine, is connected to the rear of the lower links 16, 16.

  When operating oil is supplied to the hydraulic cylinder 14a accommodated in the hydraulic cylinder case 14 by operating the hydraulic operation lever 28, the lift arms 15 and 15 are rotated upward, via the lift rod 17, the lower link 16, and the like. As a result, the rotary tiller 18 rises. On the contrary, when the hydraulic control lever 28 is operated to the lower side, the hydraulic oil in the hydraulic cylinder 14a is discharged into the transmission case 6 which also serves as a hydraulic tank, and the lift arms 15 and 15 are lowered.

  The rotary tiller 18 includes a tiller 19, a main cover 20 that covers the top of the tiller 19, a rear cover 22 that is pivotally attached to the rear of the main cover 20, and the like.

  A forward / reverse switching lever 27 for operating the forward / reverse switching device 9 is provided on the upper left side of the handle post 25 that supports the steering handle 24. When the forward / backward switching lever 27 is tilted forward from the neutral position, the aircraft moves forward. On the other hand, if you pull it backward, the aircraft will move backward.

  Next, the power transmission system will be described based on the power diagram shown in FIG.

  A main clutch 30 is provided at the rear of the engine 5, and a forward / reverse switching device 9 is provided at the rear of the transmission of the main clutch 30. The forward / reverse switching device 9 comprises multi-plate friction type hydraulic clutches 9a, 9b, which are normally maintained in a neutral position, and the forward hydraulic clutch 9a is connected by operating the forward / reverse switching lever 27 in the forward / backward direction. Alternatively, the reverse hydraulic clutch 9b is connected.

  When the forward hydraulic clutch 9a is connected, power is transmitted from the input gear 60 via the gear 62 of the counter shaft 61 and the gear 65 of the reverser shaft 64 to the forward hydraulic clutch 9a, so that the reverser shaft 64 rotates forward. .

  When the reverse hydraulic clutch 9b is connected, the reverse gear 73 is moved from the input gear 60 via the gear 62 of the counter shaft 61, the gear 66 of the counter shaft 61, and the gear 69 of the counter shaft 68. Then, power is transmitted to the reverse hydraulic clutch 9b, and the reverser shaft 64 rotates in the reverse direction.

  At the rear of the forward / reverse switching device 9, there is provided a first synchromesh main transmission 10 capable of shifting in four steps. When the actuators 31, 31 expand and contract in response to a command from the controller 88, the shifters 32, 32 are moved. Shifts forward and backward. In FIG. 2, when the front shifter 32 moves back and forth, the fourth speed and the third speed are obtained, and when the rear shifter 32 moves back and forth, the second speed and the first speed are obtained. In this case, when the main shift is switched, the hydraulic clutch of the hydraulic forward / reverse switching device 9 is first returned to neutral, and the hydraulic clutch of the forward / reverse switching device 9 is connected again after the shift. It is composed.

  A hydraulic second main transmission 11 that can be switched between high and low two stages is provided at the rear of the first main transmission 10. The front hydraulic clutch 11a is a high speed clutch, and the rear hydraulic clutch 11b is a low speed hydraulic clutch. Therefore, the main transmissions 10 and 11 in this embodiment are capable of 4 × 2 and 8 shifts.

  Further, the rear portion of the second main transmission device 11 is provided with a sub-transmission device 12 capable of three-speed shifting and having a relatively large reduction ratio as compared with the main transmission devices 10 and 11. As shown in FIG. 2, when the auxiliary shift lever 34 is operated to move the front shifter 35 back and forth, high speed (H) and medium speed (M) are obtained, and the rear shifter 35 is moved rearward. And low speed (L).

  When the auxiliary transmission 12 is operated, the main clutch 30 needs to be turned on and off. That is, the main clutch pedal 29 is depressed to operate the auxiliary transmission lever 34 in the front-rear direction or the left-right direction, and after the shift operation, the main clutch pedal 29 is released to transmit the engine rotational power to the transmission side.

  For the main transmissions 10 and 11, the speed change switch 37 and the speed reduction switch 38 provided on the knob of the sub speed change lever 34 are pushed in to change the speed (see FIG. 2). When the speed increasing switch 37 or the speed reducing switch 38 is pressed, the speed is changed step by step, and the main transmissions 10 and 11 are changed in the range from the first speed having a low speed to the eighth speed having a high speed. Then, the power decelerated by the auxiliary transmission device 12 is transmitted to the drive pinion shaft 40, and the rear wheels 3 and 3 are driven through the rear wheel differential device 41 and the final reduction device 42 in this order.

  The power branched from the rear wheel drive system in front of the rear wheel differential device 41 is used as a front wheel drive system. In the front wheel drive system, the front wheels 2 and 2 are driven at the same speed as the rear wheels 3 and 3, or the front wheels A front wheel speed increasing device 44 is provided for rotating 2 and 2 at a speed higher than that of the rear wheels 3 and 3. When the front hydraulic clutch 44a of the front wheel speed increasing device 44 is connected, the front wheel speed increasing state is established, and when the rear hydraulic clutch 44b is connected, the constant speed four-wheel driving state is established, and both hydraulic clutches 44a, 44b are engaged. When is turned OFF, only the rear wheels 3 and 3 are driven. A front wheel differential device 46 and a front wheel final reduction device 47 are provided on the front wheel drive shaft.

  In the power transmission diagram of FIG. 2, only when the auxiliary transmission 12 is at a high speed (H), if the auxiliary transmission lever 34 is moved sideways as it is, the road speed position suitable for the road traveling speed is obtained. Switch to (HH). In this case, the main shift can be selected from 5th, 6th, 7th and 8th speeds on the high speed side from 1st to 8th. When driving on the road, high speed driving is premised, so only the high speed side is prioritized, and the low speed side is automatically cut to prevent entering 1st to 4th speed even if shifting operation is performed, improving operability I am letting.

  In this embodiment, the selectable high-speed side shift pattern is four steps of 5, 6, 7, and 8. However, it is set to 3 steps of 6, 7, and 8 speeds, or 7 speeds. Alternatively, the number of shift stages may be reduced by using only two stages of 8 speeds.

  The PTO output shaft 83 is driven as follows.

  Power is transmitted from the input gear 60 to the driving gear 75 of the PTO clutch 70 via the gear 62 of the counter shaft 61, and is transmitted to the PTO clutch 70. When the PTO clutch 70 is engaged, a four-speed transmission gear mechanism that is controlled to slide by two hydraulic cylinders 76 and 77 (a third gear 81a, a first gear 81b, a fourth gear 81c, and a second gear) The PTO drive shaft 71 is driven at the speed selected with the gear 81d.

  For example, when the gear 80 a on the driven shaft 79 slid by the hydraulic cylinder 76 meshes with the gear 81 a of the PTO transmission shaft 72, the output of the PTO output shaft 83 is output from the PTO transmission shaft 72 via the output gear 82 of the driven shaft 79. Power is transmitted to the gear 85 to drive the PTO drive shaft 71 (PTO 2nd speed). Similarly, when the gear 80b meshes with the gear 81b by the hydraulic cylinder 76, the PTO 4th speed is obtained. When the gear 80c is engaged with the gear 81c by the hydraulic cylinder 77, the first PTO speed is achieved. When the gear 80d is engaged with the gear 81d by the hydraulic cylinder 77, the PTO third speed is obtained.

  Further, when the gear 80a is not engaged with the gear 81a and the reverse rotation gear 87 on the reverse rotation shaft 86 is slid to engage with the gear 81a and also engaged with the gear 80a, the PTO drive shaft 71 is reversely driven. In the case of reverse rotation, this is only the first speed.

  The farm work management system 90 adopts a cloud system, and manages information management terminals 91, portable terminals 92, cloud servers 93, user computers 94 such as farmers or farming groups, manufacturers, etc. installed in the tractor 1 in the network. Including a computer 95 for a person. The information management terminal 91 is configured to be capable of short-range communication with the portable terminal 92 via the external communication unit 96.

  When a work plan is input to the user computer 94, the work plan is output from the user computer 94 to the cloud server 93 for each field. For example, as work plan 1, work date and time: April 20, 2015, field name: A, farm machine name: tractor size 1, work machine name: rotary 3, work content: tillage, etc. As for the work plan 2, the work plan 3,..., A detailed work plan can be output for each different field B, field C,... (FIG. 4C).

  Further, the farm field information is output from the administrator computer 95 to the cloud server 93. For example, longitude / latitude information of four corners, field area, location information, etc. of each of the square fields A, B,. In FIG. 4A, it is illustrated as an agricultural field master. FIG. 2B is a machine master that displays the manufacturer and model of a tractor as an agricultural machine owned by a farming group or the like.

The portable terminal 92 is provided so that the data of the cloud server 93 can be downloaded, and a plan icon 97 ₁ , 97 ₂ ... Is created and displayed for each work plan 1, work plan 2.

  When the plan icon 97 is tapped, a work plan summary 98 is displayed (related to work plan 1 in the example), and a tap selection display unit that receives the tap operation and moves to each detail screen together with the display of the work plan summary 98. 99. That is, the tap selection display portions 99a, 99b, and 99c are associated with “detailed display”, “map”, and “work start” display. Among these, when the tap selection display portion 99a of “detail display” is tapped, the work plan detail display 100 (related to the work plan 1 in the example) is executed. In the “detailed display”, items omitted in the “summary display” such as the field area and the operator name can be displayed (FIG. 5A).

  When the “work start” tap selection display unit 99c is selected from the tap selection display unit 99, the tractor is managed by a work mode related to a predetermined work plan, for example, work plan 1. By communication between the information management terminal 91 on the tractor side and the portable terminal 92, work plan information can be transmitted from the portable terminal 92, and various information on the tractor can be transmitted from the information management terminal 91 to the portable terminal 92. 6A and 6B show examples of display on the liquid crystal screen 91A of the information management terminal 91. FIG. FIG. 6B includes changeover selection switches 91a and 91b that show a plan for the entire predetermined farming group or switch to a display relating to a tractor as the agricultural machine.

  Based on the work plan 1 in FIG. 5, if a tractor enters or tries to enter the field B other than the designation, an alarm is issued as being different from the field A of the initial plan. That is, a field entry suitability determination unit X is previously introduced into the mobile terminal 92, and a field different from the field designated by the work plan 1 by the field entry suitability determination unit X based on the information from the information management terminal 91. When determining, an alarm output such as a buzzer is output from the portable terminal 92 to the information management terminal 91. The alarm output to the information management terminal 91 drives an alarm means such as a buzzer that is appropriately disposed on the tractor. At the same time, on the screen of the portable terminal 92, a dialog display 101 is displayed, that is, “Working on the field B is about to be performed. Work plan 1 should be performed on the field A” (FIG. 7A). As shown in FIG. 8, the agricultural field approach propriety determining means X determines whether or not a tractor exists in a zone surrounded by these four corners in advance based on the longitude / latitude information of the four corners in a square field, It is determined whether or not the extension line in the traveling direction of the tractor is approaching to interfere with the zone when approaching a predetermined peripheral distance. By applying a rectangular field, the field can be regarded as a similar polygon, and the data corresponding to the shape and zone of the field can be calculated from the longitude and latitude information of each point. The tractor information management terminal 91 is provided with a GPS antenna, and constitutes means for recognizing the current position by converting it into longitude / latitude information (current position recognition means P).

  Based on the selection of the predetermined work plan, the tractor is managed in the corresponding work mode. Here, the agricultural machine or the model type of the tractor designated in the work plan is the information on the agricultural machine in advance. Compared with the type of agricultural machine stored in the management terminal 91 and the model information of the tractor, when the handled agricultural machine itself is different from the stored agricultural machine, or when the used agricultural machine is different, that is, the agricultural machine name and work When the machine name is different from the one stored in the information management terminal 91, the alarm output due to the difference in the selected device is executed from the portable terminal 92 to the information management terminal 91 together with the condition for starting the work, and the alarm buzzer attached to the agricultural machine, etc. The alarm is activated (FIG. 9) (working device selection suitability determining means Y). Therefore, when the paddy field is cultivated with a tractor having an appropriate weight, if the tractor with a heavy weight is used, there is a fear that the cultivator will be stepped on, but this can be avoided by adopting the above configuration.

  If it is determined that the work content according to the work plan cannot be dealt with, for example, the work content of tilling, the lift angle of the lift arm 15 is detected and the working machine connecting means necessary for the tilling work is detected. When the lower link height is high, it is determined that the PTO drive state is maintained, or when the lower link is low, but the PTO non-drive state is determined, the mobile terminal 92 is determined not to perform the tillage operation normally. Then, an alarm output is output to the information management terminal 91 (FIG. 10) (work content selection suitability determination means Z).

  In addition, as another example of work content abnormality, a cutter that cuts the waste from the combine information management terminal shortly, regardless of whether the dropper work used to drop and drop the combine or the knot work of the waste binding is selected. There may be work status. Furthermore, in the case of a rice planting machine, it is a case where it is not the machine state which performs this with respect to the work plan which performs a fertilization work.

  In the above description, the data such as the work plan downloaded to the mobile terminal 92 and various information from the agricultural machine such as the tractor are calculated in the mobile terminal 92. However, the work plan of the cloud server 93 is It is good also as a form which downloads directly to the information management terminal 91 of agricultural machines, such as a tractor, and performs various abnormality alarms etc. by the combination with the various information of agricultural machines itself. An example of the dialog display is shown in FIGS. FIG. 7C shows a different example of the work content selection suitability determination means Z, which is displayed when work based on the work plan is performed at a time different from the scheduled work time set in the work plan.

  As described above, the work plan downloaded to the mobile terminal 92 and the machine information data of the information management terminal 91 of the agricultural machine by the field entry suitability judging means X, the work equipment selection suitability judging means Y, and the work content selection suitability judging means Z. If it is determined that the machine or the condition is not suitable for the work based on the above, the work is interrupted or a work avoidance means is provided by outputting an alarm, so that it is possible to avoid performing a useless work. Thus, the suitability determination by the farm entry suitability determination means X, the work equipment selection suitability determination means Y and the work content selection suitability determination means Z constitutes the work suitability determination means T for a predetermined work plan. In addition to the above, the work suitability determination means T for a predetermined work plan includes various types such as a mismatch determination of the varieties of the target crop, a mismatch determination of the worker in charge.

  Based on FIG. 11, another example of a farm work management system in the case of downloading a work plan or field data from the cloud server 93 to the information management terminal 91 of the tractor that is an agricultural machine will be described. As shown in FIG. 11, tap selection display sections 104a, 104b, 104c, and 104d for “master cooperation”, “plan cooperation”, “result cooperation”, and “return” are provided on the liquid crystal screen 103 of a predetermined tractor. Among these, the plan list 105 is displayed on the liquid crystal screen 103 when the tap selection display unit 104 b for “plan cooperation” is operated. If, for example, “plan 4” is tapped in the plan list 105, the display shifts to the plan summary 106. Further, among the tap selection display units 107 displayed simultaneously on this screen, the “work start” tap selection display unit 105c is operated. In this case, the current time is compared with the time displayed on the plan date screen 106a of the plan summary 106. If the current time has not yet reached the planned time, the screen shifts to a dialog screen 108 for warning, and the scheduled execution time and the execution plan contents of the current time are displayed (FIG. 8C). Therefore, the worker can accurately grasp the work plan by confirming the warning screen.

  The plan list 105 is configured to enable distinction between “work date and time” and “work status completed” or “no work”. By rearranging in the order of “work date”, it becomes easy to make an additional work plan, and it is easy to check whether the work has been completed.

  Next, timing for downloading from the cloud server 93 to the information management terminal 91 will be described. In FIG. 12, the download of the work plan is started based on the ON operation of the key switch of the tractor (steps 101 and 102), and the download is completed (step 103). By the way, it is determined whether or not a predetermined time has elapsed since the download was executed (step 104), and when the predetermined time has elapsed, the process returns to step 102 to execute the download. If a plan change notification is received in step 104 even if a predetermined time has not elapsed (step 105), the process returns to step 102 and download is executed.

  By downloading each time a plan change notification is received, the operator can grasp the change, addition or deletion of the plan every time during the work, thereby improving the work efficiency.

  Here, the work data collected when the work is executed based on the work plan will be described.

  In the case of a tractor, vehicle basic information includes vehicle management information, vehicle driving information, and work machine basic driving information, which are collected by the information management terminal 91. Here, in addition to the GPS antenna, the information management terminal 91 includes a communication antenna or module, a G (acceleration) sensor, a memory, a battery, and the like. In addition, the vehicle management information includes, for example, a vehicle identification number such as a model, a model, and a car number, an operation time that is vehicle hour meter information, and position information provided by GPS. For example, there are engine oil pressure, engine coolant temperature, instantaneous fuel consumption, fuel remaining amount, 3P position information, travel shift position, vehicle vehicle speed information, PTO rotation speed, engine rotation speed, etc. For example, the work machine identification number (per unit area) when the work machine is a chemical spraying device, such as the work machine identification number, such as the model, model, unit, etc., and the cultivation width information and depth information when the work machine is a rotary tiller Application amount), remaining amount of agricultural chemical tank, application width information, yield information, etc.

  The information management terminal 91 collects information obtained from the tractor and analyzes and processes the data. The information includes vehicle operation information, operation time collection, fuel consumption collection, failure information, and other vehicles. There is information specific to agricultural machinery such as information, operation information for each work machine, work machine consumer goods (for example, fertilizer to be used) information, work operation route information, vehicle speed information for each work machine. Also, by analyzing and processing the data, it is possible to provide information such as maintenance timing guidance and economical driving recommendation guidance for saving fuel consumption. The maintenance time guidance is quick response to failure repair, consumable parts timing guidance, etc., and the economical driving recommendation guidance for saving fuel consumption is provision of soil information for each farm field. For convenience, the above data and the like are collectively referred to as machine operation data.

  FIG. 13 shows a configuration diagram of a tractor in-vehicle LAN system, an information management terminal 91, and a portable terminal 92 as an external device according to the present embodiment.

  That is, the tractor control device 110 includes an engine ECU 111, a work implement elevating system ECU 112, and a traveling system ECU 113, which are connected to each other via a CAN 2 (Controller Area Network). The tractor includes a portable terminal 92, an information management terminal 91, and an external communication unit 114. The tractor communicates with the information management terminal 91 via the short-range wireless communication means (for example, Blue tooth (registered trademark)). It is configured as possible. A hard disk 115 is connected to the information management terminal 91. As the portable terminal 92, a tablet PC, a smartphone, a personal computer, or the like is used. The portable terminal 92 includes a program related to driving assist control, which will be described later, and manages the control along with display on the screen.

  Further, the portable terminal 92 having the touch panel operation unit, the information communication terminal 90, and the external communication unit 114 are connected to each other by CAN1. CAN1 is connected to each control system of the tractor via the work implement elevating system ECU 112, and further connected to the work implement ECU 116 via an external connection coupler. The work implement ECU 116A shows an example of the rotary tiller 18 as the work implement. The electromagnetic solenoid for adjusting the hydraulic pressure, switching the nozzle, extending and retracting the boom, opening and closing the boom, etc. can be operated by inputting the boom extension position, the boom angle, the chemical liquid pressure, the liquid flow rate, and the remaining liquid amount. When the work implement is replaced with a medicine spraying device (not shown), connection to the work implement ECU 116B is established.

  Next, based on the flowchart of FIG. 14, the migration process of various data in the farm work management system for the purpose of storing work data will be described.

  First, when a predetermined work is performed on the function / calculation processing of the information management terminal 91 on the agricultural machine side such as a tractor, machine operation data is collected and stored (step 201). It is determined whether or not the information management terminal 91 is connected to the portable terminal 92. When the information management terminal 91 is connected, the machine operation data is transmitted to the portable terminal 92 (step 202, step 203). On the other hand, data such as field names, worker names, work contents, crops, etc., which cannot be determined by the agricultural machine, can be stored by receiving transmission from the portable terminal 92 (step 204). The received data, for example, fertilizer, agrochemical, material, worker name, work content, comment, photograph, video, etc. are associated with the corresponding work performance, for example, work time, and stored as performance data (step 205). The information management terminal 91 transmits the result data to the cloud server 93 via the wireless LAN (step 206, step 207). When the result data transmission is completed (step 208), the above procedure is repeated until the key switch is turned off (step 208). 209). Therefore, the performance data transmitted to and stored in the cloud server 93 can be confirmed by the user computer 94 or the administrator computer 95. Note that the transmission of the result data in step 206 may be in a form in which the personal computers can communicate with each other.

  On the other hand, in the figure, regarding the function / calculation processing of the portable terminal 92, when the portable terminal 92 is connected to the information management terminal 91 of the agricultural machine such as a tractor, the machine operation data of the agricultural machine is received and stored (step 301, step 302). Information and data that cannot be determined by the agricultural machine in the portable terminal 92 are input manually (step 303). As input data, for example, fertilizer, agricultural chemicals, materials, worker names, work contents, comments, etc. , Photos, videos, and the like are associated with corresponding work performance, for example, work time (step 304). It is determined whether or not the information management terminal 91 is connected (step 305), and the input data is transmitted to the information management terminal 91 (step 306). The above procedure is repeated until the unillustrated application end button is tapped (step 307).

  As described above, data is exchanged between the information management terminal 91 of the agricultural machine and the portable terminal 92 capable of near field communication. As a result, the information management terminal 91 and the portable terminal 92 have the same data. . Therefore, for example, in the form in which the work data is accumulated only in the mobile terminal 92, there is a possibility that the work data cannot be acquired due to forgetting to connect the mobile terminal 92 to the information management terminal 91 or the battery of the mobile terminal 92 is exhausted. However, the same work data can be stored on the information management terminal 91 side as described above, and the work data can be analyzed accurately. In addition, data manually input directly to the portable terminal 92 can be held in the agricultural machine side information management terminal 91, thereby eliminating data leakage. Furthermore, since data is transmitted from the information management terminal 91 to the cloud server 93 or the like, data leakage or the like is less likely to occur as compared with transmission by the portable terminal 92.

  In addition, since transmission from the information management terminal 91 to the cloud server 93 can be automatically performed via a wireless LAN connection or the like, the burden on the operator can be reduced.
