In the pattern B, when collecting the field data, the collecting device 21 saves the field data in the storage unit 24 and acquires the field data every time the collecting device 21 acquires the field data (working information). The time (data acquisition time) is also stored in the storage unit 24. As shown in FIG. 7A, the storage unit 24 of the collection device 21 includes, for example, a vehicle speed (0 km / h, 0 km / h, 1.50 km / h... 1.50 km / h), an engine speed (800 rpm). Field data such as fertilizer application amount (0.01 kg, 0.01 kg, 0.08 kg ... 0.08 kg) and data acquisition time (Apr 2 13:19:58 2012 ... Apr 2 13:32:59 2012).

Further, in the portable terminal 22 side, the agricultural machine position every time to get the agricultural machine position while stored in the storage unit 25 provided in the portable terminal 22, the time obtaining the agricultural machine position (position acquired time) also storing unit 25 Save to. As shown in FIG. 7B, the storage unit 25 of the portable terminal 22 stores, for example, the agricultural machine position of longitude (34.560269 ... 34.561269) and latitude (135.467894 ... 135.468894) and the position acquisition time (Apr 2 13:19:58 2012 ... Apr 2 13:32:59 2012).

That is, in the pattern B, the collecting device 21 and the mobile terminal 22 perform independent operations, and the farm field data, the agricultural machine position, and the like are stored.
When the acquisition of the field data is completed, the collection device 21 transmits the field data stored in the storage unit 24 and the data acquisition time to the portable terminal 22. The field data storage means 36 </ b> B of the mobile terminal 22 uses the field data and the data acquisition time transmitted from the collection device 21, and the field data and the data acquisition time based on the agricultural machine position and the position acquisition time stored in the storage unit 25 of the mobile terminal 22. The agricultural machine position is associated and stored in the storage unit 25 or the like.

Can be stored in the storage unit 25.

FIG. 9 is a block diagram of the field data collection system in the case of pattern C. The field data storage unit 36 </ b> C includes a program stored in the external terminal 37.
Even in the pattern C, when collecting the field data, the field data and the data acquisition time are stored in the storage unit 24 of the collection device 21 as in the case of the pattern B, and the position of the agricultural machine and the position acquisition time are stored in the portable terminal 22. Save in the storage unit 25. Similarly to the pattern B, the data stored in the storage unit 24 of the collection device 21 is as shown in FIG. 7A, and the data stored in the storage unit 25 of the portable terminal 21 is shown in FIG. It will be shown.

Then, when the acquisition of the field data is completed, the field data and the data acquisition time stored in the storage unit 24 are transmitted from the collection device 21 to the mobile terminal 22, and the mobile terminal 22 stores the received field data and the data acquisition time and the storage time. The agricultural machine position and the position acquisition time stored in the unit 25 are transmitted to the external terminal 37. The field data storage unit 36C of the external terminal 37 stores the field data and the agricultural machine position in association with each other based on the field data, the data acquisition time, the agricultural machine position, and the position acquisition time.

The field data storage means 36C compares the data acquisition time with the position acquisition time among the field data, data acquisition time, agricultural machine position, and position acquisition time, and the field at the time when the data acquisition time and the position acquisition time match. The data and the agricultural machine position are associated with each other and stored in the external terminal 37. Data stored in the external terminal 37 (data in which the farm field data and the agricultural machine position are associated) is as shown in FIG.

Thus, according to the field data storage means 36C provided in the external terminal 37, as shown in FIG. 8B, for example, data associating the vehicle speed, the engine speed and the fertilizer application amount, and the agricultural machine position. Can be stored in the external terminal 37.
As described above, according to the present invention, since the mobile terminal 22, the collection device 21, and the field data storage unit 36 (36 </ b> A, 36 </ b> B, 36 </ b> C) are provided, the field data when the tractor 1 is operated in the field. Can be stored in association with the position of the tractor 1 ( agricultural machine position ). For example, if the associated field data and the position of the agricultural machine are displayed, it is possible to grasp what work has been performed at which position.

  In the field, the tractor 1 (working device) may be operated for setting before starting work. In such a case, the collected field data may include data before starting work (at the time of setting). In the present invention, by using the mobile terminal 22 or the cradle 30, the field data during work and the field data other than work can be separated.

  As shown in FIG. 3, in the cradle 30, when the mobile terminal 22 is placed on any one of the back support wall 31, the lower support wall 32, and the surface support wall 33, the outer surface of the mobile terminal 22 ( A switch (detection unit) 38 that detects the placement of the mobile terminal 22 by contacting the back surface, the bottom surface, the surface, and the like is provided. When the placement of the portable terminal 22 is detected by contact between the switch 38 and the portable terminal 22, a detection signal indicating that the portable terminal 22 is placed is transmitted to a device (collector 21, control) mounted on the tractor 1. To the device 20). That is, the cradle 30 is provided with output means 40 that detects the placement of the mobile terminal 22 and outputs a detection signal detected to the outside.

  For example, the cradle 30 is provided with a cord 39 connected to the switch 38, and a first connector 42 is provided at the tip of the cord 39. On the other hand, around the fixed display device (meter panel) 43 provided on the front surface of the driver's seat 16, a second connector 44 that can be connected to the first connector 42 and connected to the vehicle communication network is provided. . After connecting the first connector 42 and the second connector 44, when the portable terminal 22 is placed on the cradle 30, a detection signal of the switch 38 indicating that the portable terminal 22 is placed is sent via the vehicle communication network. Output to devices such as the collection device 21 and the control device 20.

When the detection signal is output to the vehicle communication network, the detection signal (flag F indicating the detection signal) is added to the position of the agricultural machine or the field data at the time when the detection signal is output. . That is, the field data collection system is provided with a signal applying unit 45 that applies the detection signal output from the output unit 40 to the position of the agricultural machine and / or the field data. Similar to the agricultural field data storage unit 36, the signal applying unit 45 has two patterns: when provided in the collection device 21 (pattern A) and when provided in the mobile terminal 22 (pattern B). The signal providing unit 45 is configured by a program stored in the collection device 21 or the portable terminal 22.

  In the case of the pattern A, when a detection signal is input to the vehicle communication network by a switch of the cradle 30 or the like, the signal providing unit 45A detects a detection signal indicating that the mobile terminal 22 is placed and outputs the detection signal. The flag F which shows having performed is provided to the field data acquired substantially simultaneously with the said flag F. Specifically, the signal providing means 45A uses the detected signal as a signal (flag F) indicating the start time when the operation of the tractor 1 is started, and adds a flag F indicating the start time to the field data.

As shown in FIG. 5 (a), for example, when the collection device 21 acquires the field data of the vehicle speed (1.50km / h), the engine speed (818rpm), and the fertilizer application amount (0.08kg), the detection signal Is input to the vehicle communication network, the signal giving means 45A gives a flag F indicating the start time to the field data of the vehicle speed (1.50 km / h), the engine speed (818 rpm), and the fertilizer application amount (0.08 kg). To do. The field data to which the flag F is added by the signal applying unit 45A is associated with the agricultural machine position (latitude 34.560269 and longitude 135.467894) by the field data storage unit 36A as shown in FIG. 5B. When the field data and the agricultural machine position are associated with each other after the flag F is given, it becomes as shown in FIG.

It has been described that the flag F is given to the field data. Instead, as shown in FIG. 5B, the signal giving means 45A uses the agricultural machine position (latitude 34.560269, longitude acquired simultaneously with the field data). 135.467894) may be given a flag F. Also in this case, when the field data and the agricultural machine position are associated with each other after the flag F is given, the result is as shown in FIG.
As shown in FIG. 6, in the case of pattern B, when a detection signal is input to the vehicle communication network by a switch of the cradle 30, the control device 20 or the collection device 21 first outputs the detection signal to the mobile terminal 22. To do. When detecting the detection signal, the signal applying unit 45B sets the detected time as the start time when the work of the tractor 1 is started, and adds a flag F indicating the start time to the agricultural machine position detected by the mobile terminal 22. For example, as shown in FIG. 7B, when the signal giving means 45B detects the detection signal when the mobile terminal 22 detects the latitude 34.560269 and the longitude 135.467894 (Apr 2 13:20:00 2012), A flag F indicating the start time is given to latitude 34.560269 and longitude 135.467894 (Apr 2 13:20:00 2012). After providing the flag F, the agricultural machine position to which the flag F is added by the signal applying unit 45B is associated with the field data by the field data storage unit 36B, and the associated agricultural machine position and the field data are shown in FIG. As shown.

As described above, when the signal giving means 45 detects the detection signal, it gives the start time to any one of the field data, the agricultural machine position , the field data, and the agricultural machine position. It is possible to grasp and to determine whether the field data is before the work starts or after the work starts. That is, as shown in FIG. 5C and FIG. 8B, it can be recognized that the field data after the flag F is collected after the start of the work. From the flag F, it is possible to distinguish between the field data before starting work and the field data after starting work. As a matter of course, the storage unit of the collection device 21 stores data in which the field data, the agricultural machine position, and the start time are associated.

  In the above-described embodiment, the detection signal is output from the cradle 30 to the vehicle communication network. However, the detection signal may be output from the mobile terminal 22 instead of the vehicle communication network. For example, a power connector connected to the battery is provided on the front side of the driver seat 16, the left and right sides of the driver seat 16, or the lower side of the driver seat 16, and the portable terminal 22 is set (placed) on the cradle 30. A set terminal (detection unit) that supplies power to the charging terminal on the terminal 22 side is provided, and the set terminal and the power connector can be connected via a cable or the like. If it does in this way, the set terminal by the side of the cradle 30 and the charge terminal of the portable terminal 22 will contact, and the electric current of charging when the charge of the said portable terminal 22 was started will be detected by detecting the placement of the portable terminal 22 It can be a signal. When the detection signal is output not to the vehicle communication network but to the portable terminal 22 and the signal providing means 45 is provided in the collection device 21, the detection signal is transmitted from the portable terminal 22 to the collection device 21. The When a detection signal is output to the mobile terminal 22 and the signal providing means 45 is provided in the mobile terminal 22 itself, no detection signal is output to the collection device 21. In addition, in the pattern C shown in FIG. 9, it is preferable to provide the signal provision means 45 in either the collection device 21 or the portable terminal 22.

As mentioned above, according to this invention, in addition to the portable terminal 22, the collection apparatus 21, and the agricultural field data storage means 36, the mounting apparatus (cradle) 30, the output means 40, and the signal provision means 45 (45A, 45B) are provided. Therefore, the field data can be separated and organized starting from the fact that the portable terminal 22 is placed on the placement device of the portable terminal 22.
Further, when the portable terminal 22 owned by the operator who operates the tractor 1 is placed on the cradle 30 and the portable terminal 22 functions as a device for detecting the position of the tractor 1 (the portable terminal 22 is used as the device of the tractor 1). Since the operation of the tractor 1 is started (when the function is exhibited), the collection of the field data after the start of the operation can be easily performed.

When collecting the field data, the field data before and after the start of work can be easily organized without providing a switch or the like for notifying the fixed display device 43 of the tractor 1 of the start of work (start of collecting field data). be able to.

When an application constituting the display unit 47 is activated in the portable terminal 22, the display unit 47 first requests the tractor 1 side (the control device 20) to transmit display information. The control device 20 receives the display information transmission request from the portable terminal 22 (display unit 47) and transmits the display information to the portable terminal 22. Upon receiving the display information, the display unit 47 displays the display information on the display unit 22A.

As shown in FIG. 11A, the display unit 22A displays the same display information as the fixed display device 43 displays, such as the engine speed, fuel, and water temperature. It should be noted that the display information displayed on the display unit 22A may be different from the fixed display device 43 such as the PTO rotation speed and work device information (dispersion amount, etc.) as shown in FIG. Good.
In addition, it is preferable that the display information displayed on the mobile terminal 22 can be appropriately set on the mobile terminal 22, and in particular, information related to the operation of the tractor 1 is displayed on the display unit 22 </ b> A of the mobile terminal 22. It is preferable to do.

  The portable terminal 22 includes an output unit 48. The output means 48 is composed of a program stored in the mobile terminal 22, detects that the display information is displayed on the display unit 22A, and outputs this detection signal. Specifically, when the display unit 22A of the portable terminal 22 starts displaying the display information as shown in FIGS. 11A and 11B, the output unit 48 detects that the display has started. The detection signal is output to the collection device 21 or the portable terminal 22.

When the collecting device 21 is provided with a signal providing unit 45A (when the configuration is the same as the pattern A of the first embodiment), the output unit 48 outputs a detection signal to the collecting device 21. The signal giving means 45A sets the time when the display information is displayed on the display unit 22A of the mobile terminal 22 (the time when the collection device 21 receives the detection signal) as the start time when the work by the tractor 1 is started. Similar to the form, the start time is given to the position of the agricultural machine , the field data, and the like.

When the signal applying unit 45B is provided in the portable terminal 22 (when it has the same configuration as the pattern B of the first embodiment), the output unit 48 outputs a detection signal to the inside of the portable terminal 22 (signal providing unit 45B). To do. The signal applying means 45B uses the time when the detection signal is output as the start time, and gives the start time to the agricultural machine position as in the first embodiment.
As described above, according to the present invention, since the output unit 48 and the signal providing unit 45 are provided in addition to the mobile terminal 22, the collection device 21, and the field data storage unit 36, display information is displayed on the display unit 22 </ b> A of the mobile terminal 22. The field data can be carved and organized starting from the display of.

When the portable terminal 22 owned by the operator who operates the tractor 1 is caused to function as a display monitor (when the portable terminal 22 performs a function as a device of the tractor 1), the work of the tractor 1 starts (work on the field). The field data is collected when the operation is started), the field data can be easily collected after the work is started.
Furthermore, when collecting field data, the field data before and after the start of work can be easily organized without providing a switch or the like for notifying the fixed display device 43 of the tractor 1 of the start of work (start of collecting field data). It can be performed.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims. In the embodiment described above, information (work information) related to work when working on the agricultural machine 1 is field data, but information other than work (for example, information indicating the soil state of the field) or the like is given to the agricultural machine 1. Information relating to the work and information other than the work may be collected as field data by detecting with a mounted sensor or camera.

Further, the field data storing means 36A is in the pattern A, and sequentially acquires the field data and agricultural machine position, had association with agricultural machine position every time to get the field data, instead of this, the field data storing means 36B In the same manner as described above, the field data and the data acquisition time are accumulated in the collecting device 21 (storage unit 24) in advance, and after the acquisition of the field data, the agricultural machine position and the position acquisition time are collectively performed from the portable terminal 21. , And using the agricultural machine position and position acquisition time acquired collectively from the mobile terminal 21 and the field data and data acquisition time accumulated in the storage unit 24, the field data and the agricultural machine position may be associated with each other. Good.

On the contrary, the field data storage means 36B in the pattern B uses the field data and the data acquisition time accumulated in the storage unit 24 of the collection device 21 and the agricultural machine position accumulated in the storage unit 25 of the portable terminal 22 after the acquisition of the field data. and had association with field data and agricultural machine position using the position acquisition time, similarly to the field data storing means 36A in the pattern a, each time to get the field data and agricultural machine position, field data and agriculture A machine position may be associated. In this case, it is necessary to transmit the acquired field data to the portable terminal 22 every time the collection device 21 acquires the field data.
