  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(Embodiment 1)
The configuration and operation of the work vehicle 100 and the tablet terminal device 200 according to the present embodiment will be specifically described with reference to FIGS.

  FIG. 1 is a block diagram of work vehicle 100 and tablet terminal device 200 according to the first embodiment of the present invention. FIG. 2 is a block diagram of work vehicle 100 and tablet terminal device 200 according to the first embodiment of the present invention. FIG. 3 is a left side view, and FIG. 3 is a plan view of work vehicle 100 and tablet terminal device 200 according to Embodiment 1 of the present invention.

  The work vehicle 100 includes left and right front wheels 101 and rear wheels 102, a steering handle 103, a seedling planting unit 140, a seedling planting unit state detection unit 150, a mechanical vehicle speed sensor 160, and the like. Work vehicle 100 also includes a GPS information acquisition unit 110, a work vehicle electronic control unit 120, a work vehicle communication unit 130, and the like.

  The tablet terminal device 200 includes an input / output unit 210, a memory 220, a central processing unit 230, a touch panel 240, a clock 250, and the like.

  The work information includes information including seedling planting unit state information related to the state of the seedling planting unit 140 detected by the seedling planting unit state detection unit 150, detected vehicle speed information related to the detected vehicle speed detected by the mechanical vehicle speed sensor 160, and the like. It is.

  Such work information is acquired by the GPS information acquisition unit 110 in real time one after another according to the acquisition timing of the time interval Δt (for example, Δt = 0.2 (seconds)), for example. Along with the information, the work vehicle electronic control unit 120 and the work vehicle communication unit 130 transmit the information using short-range wireless communication or the like, and the input / output unit 210 sequentially receives the information in real time.

  The work information is recorded in the memory 220 by the central processing unit 230 in association with the GPS time information and the GPS position information. When the GPS time information is not received, the work information is Correlated and recorded in the memory 220.

  The information recording format of these pieces of information is, for example, a format as shown in FIG.

  FIG. 4 is an explanatory diagram for explaining the information recording format according to the first embodiment of the present invention.

  In a state where communication with the GPS satellite is possible, work information and accurate and detailed GPS time information and GPS position information using the GPS satellite are recorded in association with each other, and communication with the GPS satellite is not possible. Even in a possible state, work information and clock time information are recorded in association with each other. Therefore, the convenience for the worker who wants to browse the work information on the tablet terminal device and utilize it is greatly improved.

  Of course, it is recognized that the clock time information does not match the GPS time when communication with the disconnected GPS satellite is restored, or when the GPS satellite search operation is completed due to power-on of related equipment, etc. In such a case, the clock time information may be corrected in consideration of an offset based on GPS time that is considered to be more accurate.

  (1a) When the detected vehicle speed information indicates that the detected vehicle speed has not reached a predetermined level, the central processing unit 230 may not record the GPS position information or record the GPS position information.

  For example, when the work vehicle 100 is stopped, that is, when the detected vehicle speed is substantially zero, the influence of the rotation of the earth and the revolution of the GPS satellite is increased in principle. It is not always accurate, and when GPS position information is recorded, it may be adversely affected.

  Therefore, in such a case, the GPS position information does not have to be recorded, and the acquisition timing of the time interval Δt (for example, 0.5 (seconds) ≦ Δt ≦ 5 (seconds)) larger than usual is set. It may be recorded by thinning out by using. In the latter, generation of unnatural data in the vehicle movement locus calculated based on the GPS position information due to the influence of the above-described rotation of the earth and the revolution of the GPS satellite is considerably suppressed.

  Of course, the GPS position information while the vehicle is stopped from immediately after the vehicle is stopped to immediately after the vehicle is resumed has little meaning in the first place. This is because work is often rarely performed while the vehicle is stopped, and there is little temporal change in work information relating to vehicle speed, seedling remaining amount, fertilizer remaining amount, and the like. If GPS position information having no such meaning is not recorded, the recording area of the memory 220 is not wasted and the processing load on the central processing unit 230 is reduced.

  (1b) Moreover, the central processing unit 230 does not need to record the GPS position information when the GPS position information does not match the detected vehicle speed information.

  For example, when the vehicle travel distance calculated based on the GPS position information greatly differs from the vehicle travelable distance calculated based on the detected vehicle speed information, the error in the GPS position data is a communication error with the GPS satellite. Since there is a high possibility that it has occurred due to a disruption or the like, GPS position information that may cause harmful effects may be discarded without being recorded.

  More specifically, for example, as shown in FIG. 5, a sudden change or reversal of the vehicle movement direction or a sudden increase in the vehicle movement distance is calculated based on the GPS position information. If the calculated vehicle speed calculated based on the GPS position information by the differential operation greatly exceeds the detected vehicle speed, the reliability of the GPS position information is considered not so high.

  FIG. 5 is an explanatory diagram for explaining the vehicle movement locus calculated based on the GPS position information according to the first embodiment of the present invention.

  Such extreme combinations of vehicle movement trajectories often occur, for example, when the above-described GPS position information is not thinned out even though the work vehicle 100 is stopped.

  Of course, if for some reason the reliability of the GPS position information is considered to be higher than the reliability of the detected vehicle speed information, the GPS position information may be recorded and the detected vehicle speed information may be discarded without being recorded. Good.

  (1c) The central processing unit 230 also calculates the calculated vehicle speed related to the calculated vehicle speed calculated based on the GPS position information when the detected vehicle speed information indicates that the detected vehicle speed has not reached the predetermined level. The information may be recorded instead of the detected vehicle speed information.

  Since important agricultural information such as the vehicle travel distance and the work area that is the product of the vehicle travel distance and the work width is calculated using the vehicle speed, it is desirable that the mechanical vehicle speed sensor 160 has higher performance. .

  However, the mechanical vehicle speed sensor 160 is typically a rotation sensor that detects the rotational speed of the drive shaft. If the rotational speed of the drive shaft exceeds a predetermined rotational speed, the accuracy of the detected vehicle speed is considerably high. High, but if not, the accuracy of the detected vehicle speed is not very high.

  Therefore, when the detected vehicle speed does not exceed a predetermined speed (for example, 0.2 m / sec) corresponding to the sensor detection lower limit value, the calculated vehicle speed information may be recorded instead of the detected vehicle speed information.

  Of course, as described above, when the detected vehicle speed is substantially zero, the influence of the rotation of the earth and the revolution of the GPS satellite becomes larger in principle, so the GPS position information is not necessarily accurate. .

  However, when the mechanical vehicle speed sensor 160 is a tractor sensor, the sensor detection lower limit value is approximately 0.3 m / second, and when the mechanical vehicle speed sensor 160 is a combine harvester sensor, the sensor detection lower limit value. Is approximately 0.02 m / sec.

  Therefore, if the detected vehicle speed is not substantially zero, the reliability of the calculated vehicle speed information may not be so high, but is considered to be higher than the reliability of the detected vehicle speed information.

  Of course, when the detected vehicle speed does not exceed a predetermined speed (for example, 0.2 m / sec) corresponding to the sensor detection lower limit value, information based on the detected vehicle speed, such as detected vehicle speed information, is calculated vehicle speed information. May be recorded after correction using.

(Embodiment 2)
The configuration and operation of the work vehicle 100 and the tablet terminal device 200 according to the present embodiment will be specifically described with reference to FIG.

  FIG. 6 is a block diagram of work vehicle 100 and tablet terminal device 200 according to Embodiment 2 of the present invention.

  The configurations and operations of work vehicle 100 and tablet terminal device 200 according to the present embodiment are similar to the configurations and operations of work vehicle 100 and tablet terminal device 200 according to the first embodiment described above.

  However, in the present embodiment, work vehicle 100 includes vehicle turning detection unit 171, and the work information includes vehicle turning information related to the turning of work vehicle 100 detected by vehicle turning detection unit 171.

  Then, the central processing unit 230 (1) when the vehicle turning information indicates that the work vehicle 100 is turning, calculates the calculated vehicle speed information related to the calculated vehicle speed calculated based on the GPS position information, (2) The vehicle turning information indicates that the work vehicle 100 is turning, but if the GPS position information is not input, the detected vehicle speed information is recorded. .

  The vehicle turning detection unit 171 is typically a steering handle potentiometer that detects the operation state of the steering handle 103.

  Because it is preferable that the planting end position of the work line and the planting start position of the next work line are aligned, it is considered more reliable when turning at low speeds. The calculated vehicle speed information is preferably recorded instead of the detected vehicle speed information.

(Embodiment 3)
The configuration and operation of the work vehicle 100 and the tablet terminal device 200 according to the present embodiment will be specifically described with reference to FIG.

  FIG. 7 is a block diagram of work vehicle 100 and tablet terminal device 200 according to Embodiment 3 of the present invention.

  The configurations and operations of work vehicle 100 and tablet terminal device 200 according to the present embodiment are similar to the configurations and operations of work vehicle 100 and tablet terminal device 200 according to the first embodiment described above.

  However, in the present embodiment, work vehicle 100 includes vehicle coasting work detection unit 172, and the work information includes vehicle coasting work related to the coasting work of work vehicle 100 detected by vehicle coasting work detection unit 172. Contains information.

  Then, the central processing unit 230 (1) When the vehicle coasting work information indicates that the work vehicle 100 is working on the coast, the calculation related to the calculated vehicle speed calculated based on the GPS position information. When vehicle speed information is recorded instead of the detected vehicle speed information, and (2) vehicle coasting work information indicates that work vehicle 100 is working on the coast, but GPS position information is not input Records the detected vehicle speed information.

  The vehicle coasting work detection unit 172 is typically a turning interlocking mechanism switch sensor that detects an operation state of a turning interlocking mechanism switch that switches an on / off state of the turning interlocking mechanism that is turned off during the coasting work. .

  Such a turning interlocking mechanism automatically moves the seedling planting part 140 up and down in response to the operation of the steering handle 103 at the time of turning at the end of the field and automatically starts seedling planting. It is a mechanism for performing. The turning trajectory when the turning interlock mechanism should be used is a fan-shaped arc with a central angle of about 180 degrees, but the turning trajectory when the coasting work is performed along the edge of the field is When turning at a corner, it is a fan-shaped arc with a central angle of about 90 degrees. Therefore, when the dredging work is performed, the turning interlocking mechanism is turned off by the operation of the turning interlocking mechanism switch so that the lowering of the seedling planting unit 140 and the seedling planting are not performed at unnecessary timing. Therefore, it can be determined by detecting the operation state of the turning interlock mechanism switch whether or not the work vehicle 100 is working on the heel.

  At the time of dredging work where low-speed traveling is often performed due to strong soil resistance at the edge of the field, calculated vehicle speed information that is considered to be more reliable is recorded instead of detected vehicle speed information So desirable.

(Embodiment 4)
The configuration and operation of the work vehicle 100 and the tablet terminal device 200 according to the present embodiment will be specifically described with reference to FIG.

  FIG. 8 is a block diagram of work vehicle 100 and tablet terminal device 200 according to the fourth embodiment of the present invention.

  The configurations and operations of work vehicle 100 and tablet terminal device 200 according to the present embodiment are similar to the configurations and operations of work vehicle 100 and tablet terminal device 200 according to the first embodiment described above.

  However, in the present embodiment, work vehicle 100 includes travel location inclination detection unit 173, and the work information includes travel location inclination information related to the inclination of the travel location detected by travel location inclination detection unit 173.

  Then, the central processing unit 230 calculates the vehicle travel distance based on the GPS position information, and when the travel location tilt information indicates that the travel location is inclined, the travel location tilt information is used. Correct the vehicle mileage.

  The travel location inclination detection unit 173 is typically an angle sensor that detects the vehicle body inclination angle of the work vehicle 100.

  The vehicle movement distance d calculated based on the GPS position at which the angle sensor has started to detect an inclination angle exceeding a predetermined inclination angle and the GPS position at which the angle sensor has detected an inclination angle exceeding the predetermined inclination angle is: It is often smaller than the vehicle travel distance D calculated based on the vehicle travel time corresponding to these two GPS positions and the detected vehicle speed.

  This is because, even when the traveling place is inclined, the GPS satellite recognizes that the work vehicle 100 is traveling on a flat horizontal plane.

For example, in the case where the work vehicle 100 is traveling in the direction of the maximum inclination as shown in FIG. 9 in the traveling area where the maximum inclination angle θ is inclined, the two vehicle movement distances d described above are used. Between D and D (Equation 1)
d = D × cos θ ≦ D
Is established.

  FIG. 9 is an explanatory view for explaining the inclined traveling place according to the fourth embodiment of the present invention.

  However, although the vehicle movement distance D is often closer to the true vehicle movement distance than the vehicle movement distance d, the detected vehicle speed information is not always accurate when the maximum inclination angle θ is large.

  Therefore, important agricultural information such as the vehicle travel distance calculated based on the GPS position information and the work area that is the product of the vehicle travel distance and the work width is corrected using the travel slope information. It is desirable.

  Even in an inclined field, the travel distance that the work vehicle 100 actually traveled can be obtained accurately, so that the accuracy of work information related to consumption of materials such as seedlings, fertilizer and fuel, and work time is improved. In addition, the occurrence of excess or deficiency of materials used when working in the same field or a field with similar conditions can be suppressed, and planned farm work can be performed.

(Embodiment 5)
The configuration and operation of the work vehicle 100 and the tablet terminal device 200 according to the present embodiment will be specifically described with reference to FIG.

  FIG. 10 is a block diagram of work vehicle 100 and tablet terminal device 200 according to the fifth embodiment of the present invention.

  The configurations and operations of work vehicle 100 and tablet terminal device 200 according to the present embodiment are similar to the configurations and operations of work vehicle 100 and tablet terminal device 200 according to the first embodiment described above.

  However, in the present embodiment, work vehicle 100 includes material replenishment detection unit 174, and the work information includes material replenishment information related to material replenishment detected by material replenishment detection unit 174.

  The central processing unit 230 does not record the GPS position information when the material supplement information indicates that the material is supplemented.

  The material replenishment detection unit 174 typically detects a decrease in excess of a predetermined amount of materials such as seedlings, seeds, and fertilizers mounted on a work device such as the seedling planting unit 140, and detects the seedling planting unit state detection. Detecting the state of a work auxiliary device such as a rotary spare seedling frame and a fertilizer handling device that assists in loading the material reduction sensor such as the portion 150, materials such as seedlings, seeds and fertilizers into the work vehicle 100 Auxiliary device sensor, a power clutch mechanism sensor for detecting a state of a power clutch mechanism for switching on / off state of driving force to a working device such as a seedling planting unit 140, a working device such as a seedling planting unit 140, a front wheel 101 and A shift device that detects the state of a transmission such as HST (Hydro Static Transmission) that switches the shift state of the driving force to the rear wheels 102. Sensor, etc.

  For example, when the state of the decrease switch of the seedling planting part state detection unit 150 changes from OFF to ON, the work vehicle 100 is stopped and the seedling loading is progressing, and the rotary preliminary seedling frame When the seedling rail is extended, seedlings are loaded. When the main clutch mechanism is in the locked state, the work vehicle 100 is stopped, and when the HST is in the neutral state, the work vehicle 100 is It is reasonable to judge that it has stopped.

  Of course, when the state of the decrease switch of the seedling planting state detection unit 150 changes from off to on, the work vehicle 100 has already stopped, and the timing at which the state of the decrease switch changes from off to on is As described above, the timing for stopping recording of GPS position information, which is not necessarily accurate, is slightly late.

  However, for example, if the recording of the GPS position information during the subsequent vehicle stop until the vehicle is resumed is stopped, the GPS position information that is considered to be not highly reliable in the majority of the vehicle stopped. Not recorded.

  If such GPS position information is not recorded, the recording area of the memory 220 is not wasted and the processing load on the central processing unit 230 is reduced, which is desirable.
