Also in the agricultural field, in order to detect the position of an agricultural machine working on a field, development of a position detection technique using a GPS (Global Positioning System) is in progress.
For example, as shown in Patent Document 1, there is a technique for detecting the position of a farm field where an agricultural machine exists by mounting a GPS on the agricultural machine.

Patent Literature 1 is a technique for recognizing a field position using a GPS-equipped work machine, and recognizes a field position where GPS data detected by the GPS mounted on the work machine overlaps position coordinates. A recognition system is disclosed. In this field position recognition system, the overlap between GPS data and field position data is determined based on whether or not the GPS data is a predetermined ratio or more in the field position data, or the average position of the GPS data is the field position data. The determination is based on whether or not the distance is within a predetermined distance from the average position.

According to the field position recognition system of Patent Document 1, it is supposed that a field can be specified using the analyzed position coordinates without electronic map data.
In recent years, attempts have been made to collect and utilize field data relating to the field, such as the contents of work on the field, in order to improve the efficiency of work plans in the field and improve the quality of the harvest. For example, Patent Document 2 discloses a technique for collecting field data using an agricultural machine such as a tractor or a combine.

A data collection device for an agricultural machine disclosed in Patent Document 2 is attached to the agricultural machine, and is configured to transmit data on the machine side to a management terminal via a communication line. In the apparatus, a data file set in the storage device of the management terminal is automatically created, and the file name includes at least the date of work, the machine identification code, the operator One or more of each element of name and field number is included.

According to the data collection device of Patent Document 2, it is said that work data can be easily analyzed in a field without using a personal computer.

As shown in FIG. 1, the work information extraction system 1a uses a satellite positioning system 2 such as a global positioning system (GPS). As is well known, the satellite positioning system 2 is a system including a plurality of positioning satellites 21 in an artificial satellite orbit, and each positioning satellite 21 includes position information indicating coordinate positions based on latitude and longitude on the earth, and A positioning signal including time information is transmitted to the ground.

The work information extraction system 1a receives the positioning signal from the satellite positioning system 2 to detect the receiving position (that is, the current position) of the positioning signal, the contents of the farm work performed on the farm 8 and the farm work and the farm work. And agricultural machinery (agricultural equipment) such as a tractor and a combiner that collects field data and the like as the agricultural work information (work information). In this embodiment, the tractor 4 is illustrated as an example of an agricultural machine. If the mobile terminal 3 is in the tractor 4 (particularly in the driver's seat of the tractor 4), the current position of the mobile terminal 3 detected based on the positioning signal from the satellite positioning system 2 is the current position of the tractor 4. It can be handled as a certain work machine position (work machine position information).

Then, the work information extraction system 1a uses the work information collected by the tractor 4 and the work machine position detected by the mobile terminal 3 (work machine position information) as the farm 5 that owns the tractor 4 or the farm management center 6 of the farming group. Is stored in an information processing terminal 7a such as a personal computer (PC) installed in the computer, and the work information corresponding to the position of a specific field 8 is extracted.

The fertilizer application device 97 adjusts the amount of fertilizer applied according to the vehicle speed of the tractor 4 under the control of the operation panel, and applies the fertilizer so that the fertilizer is applied according to the set value on the operation panel.
Here, between the fertilizer spreading device 97 and the operation panel, a control signal is transmitted and received in a wired or wireless manner. The operation panel may be installed in the vicinity of the fertilizer spreading device 97 or may be installed in the vicinity of the driver seat 94 in the cabin.

As shown in FIG. 4, the tractor 4 configured as described above leaves the barn of the farmer 5 and heads to the farm field, and applies fertilization, for example, in the

farm fields

8A and 8B among the plurality of farm fields 8 (8A to 8D). Suppose you do. The portable terminal 3 brought into the tractor 4 by the worker continues to acquire the position of the work implement from the start of the barn of the farmer 5 until the fertilization in the

fields

8A and 8B is completed and the fertilizer is returned to the barn. The work machine position acquired at this time and the position acquisition time associated with the work machine position are held in the position information acquisition unit 31 of the portable terminal 3 as the position information table 300 shown in FIG.

In the position information table 300 of FIG. 3, at the position acquisition time “Apr 2 13:00:10 2012”, the farmer 5 leaves the barn to finish fertilization in the

fields

Returning to FIG. 2, the tractor 4 includes a timing device (timer) 42 and a work information acquisition device (work information acquisition unit) 43 in addition to the control device (control unit) 41 described above. . The control unit 41, the timing unit 42, the work information acquisition unit 43, and the operation panel of the fertilizer application device 97 are connected by a vehicle communication network (for example, Controller Area Network, FlexRay, etc.), and transmit / receive signals (data) to / from each other. I do. Further, the control unit 41 has a short-range wireless communication (WiFi (registered trademark), Bluetooth (registered trademark), ZigBee (registered trademark), etc.) function. Send and receive data between.

The time measuring unit 42 is a clock that acquires time information included in the positioning signal transmitted from the positioning satellite 21 from the mobile terminal 3 via the control unit 41 and keeps the time synchronized with the mobile terminal 3. That is, the time of the time measuring unit 42 is synchronized with the time of the portable terminal 3 with the satellite positioning system 2 as a reference.
The work information acquisition unit 43 acquires farm work information (work information) related to farm work performed by an agricultural machine such as the tractor 4 and acquires a work information acquisition time, which is a time when the work information is acquired, from the time measuring unit 42. is there. The work information acquisition unit 43 stores the acquired work information and work information acquisition time.

For example, when the fertilizer spraying device 97 is used as a work device, the work information acquisition unit 43 acquires the fertilizer spraying amount sprayed by the fertilizer spraying device 97 as work information from the fertilizer spraying device 97 or the like. Specifically, when the fertilizer application device 97 is operated, the fertilizer application amount is output on the vehicle communication network. The work information acquisition unit 43 acquires the fertilizer application amount output on the vehicle communication network.

In addition to the fertilizer application amount described above, the work information acquisition unit 43 also acquires, from the control unit 41, the vehicle speed when the fertilizer application amount is acquired, the rotational speed of the PTO, and the like.
In addition, the work information acquisition unit 43 acquires the time when the work information is acquired from the time measuring unit 42 as the work information acquisition time, and stores the work information and the work information acquisition time in association with each other.
The fertilizer spraying device 97 includes means for changing the fertilizer spraying amount according to the vehicle speed of the tractor 4, and the fertilizer spraying amount discharged from the fertilizer spraying device 97 per unit time increases as the vehicle speed increases. If the vehicle speed is low, the amount of fertilizer sprayed per unit time decreases. Therefore, the work information acquisition unit 43 can acquire the fertilizer application amount according to the change in the vehicle speed.

In the uppermost part of the work information table 400 shown in FIG. 5, as the work information acquisition time, the time “Apr 2 散布 13:20:00 時刻 2012” is the time when the fertilizer spreading device 97 starts operating, that is, the time when the detection of the fertilizer spreading amount starts. As the work information, a vehicle speed of 1.50 km / h, a PTO rotation speed of 318 rpm, and a fertilizer application amount of 0.08 kg are shown in association with each other. When detection of the fertilizer application amount starts, the work information acquisition unit 43 detects the work information every second, and stores the detected work information and the work information acquisition time in association with each other in the work information table 400. The work information acquisition unit 43 ends the detection of the work information when the operation of the fertilizer application device 97 ends and the fertilizer application amount cannot be detected.

In the work information table 400 shown in FIG. 5, the acquisition of work information starts at time “Apr 2 13:20:00 2012” and then ends at time “Apr 2 13:32:59 2012”. , Has started again at time "Apr 2 13:45:18 2012". Acquisition of resumed work information ends at time “Apr 213: 53: 26 2012”.

The actual result information storage unit 71a acquires, for example, the position information table 300 shown in FIG. 4 and the work information table 400 shown in FIG. 5 from the portable terminal 3, and based on the acquired both tables, the actual result information table shown in FIG. 500 is created and saved.
FIG. 6 is a diagram showing a record information table 500. The performance information table 500 is a table obtained by combining the position information table 300 and the work information table 400 of FIG.

Specifically, the record information storage unit 71a compares the position acquisition time in the position information table 300 with the work information acquisition time in the work information table 400, and detects a work information acquisition time that matches the position acquisition time. Then, the record information storage unit 71a obtains the record information table 500 by combining the position information table 300 and the work information table 400 so that the position acquisition time and the work information acquisition time that coincide with each other are overlapped. Accordingly, the work position and the work information are associated with each other at the position acquisition time and the work information acquisition time that coincide with each other.

For example, in the performance information table 500 of FIG. 6, the work machine position “latitude: 34.560269, longitude: 135.467894” at the position acquisition time or work information acquisition time “Apr 2 13:20:00 2012” and the work information “vehicle speed: 1.50, PTO rotation speed: 318, fertilizer application amount: 0.08 ”.
The work place storage unit 73 stores a work place map (a farm field map) indicating the position of a work place such as a farm field on which an agricultural machine performs work. The field map is composed of data related to a plurality of fields (data on the latitude and longitude of the field), for example, a map as shown in FIG. 4, and a plurality of fields 8A to 8D are shown as plan views. It is.

Further, when a field on the field map is selected (designated), the work location storage unit 73 receives latitude and longitude information (latitude / longitude information) indicating the position of the selected (designated) farm field. The latitude / longitude information is output to the designated work information extraction unit 72a described later as the designated position. For selection (designation) of the field, for example, a field map is displayed on the display device of the information processing terminal 7a, and the field is selected from the field map displayed on the display device using the input device of the information processing terminal 7a. Do this by selecting.

When the designated work information extraction unit 72a receives the latitude / longitude information (designated position) of the field position output from the work place storage unit 73, the designated work information extraction unit 72a refers to the result information table 500 stored by the result information storage unit 71a and receives the received field. The work information associated with the work machine position (work machine position information) that matches the position is extracted from the result information table 500.
Specifically, when the designated work information extraction unit 72a receives the position information (latitude and longitude) of the field 8A output from the work place storage unit 73 by the designation of the field 8A on the field map, the result information table 500 Refer to Then, the designated work information extraction unit 72a extracts a work machine position that matches the position information (designated position) of the designated field 8A on the performance information table 500 and associates it with the extracted work machine position. Extract (acquire) work information. Furthermore, the designated work information extraction unit 72a holds the extracted work information as work information for the field 8A. By this series of operations, work information of the farm field 8A designated on the farm map is obtained.

As described above, in the work information extraction system 1a according to the present embodiment, the position information acquisition unit 31 provided in the mobile terminal 3 acquires the work machine position information indicating the position of the agricultural machine and also acquires the work machine position information. The position acquisition time, which is the time, is acquired, and the position information table 300 is created. On the other hand, the work information acquisition unit 43 provided in the tractor 4 acquires the work information related to the work performed by the tractor 4, acquires the work information acquisition time that is the acquisition time of the work information, and creates the work information table 400. To do. In addition, the record information storage unit 71 a of the information processing terminal 7 a provided in the farmer 5 acquires the position information table 300 indicating the work machine position information from the position information acquisition unit 31 of the mobile terminal 3, and the work of the tractor 4. The work information table 400 indicating the work information is acquired from the information acquisition unit 43, and the work machine position information of the acquired position information table 300 and the work information of the work information table 400 are associated with each other by the position acquisition time and the work information acquisition time. Saved in the information table 500. The designated work information extraction unit 72a of the information processing terminal 7a extracts and acquires the work information associated with the work machine position information based on the result information table 500 stored by the result information storage unit 71a and the specified position.

The operation of the work information extraction system 1a according to the present embodiment will be described with reference to FIGS. FIG. 7 is a flowchart showing the operation of the work information extraction system 1a, and FIG. 8 is a diagram showing the result information table 500 and the work information for each field extracted from the result information table 500.
First, the mobile terminal 3 is turned on before or immediately after the operator gets on the tractor 4, and the position information acquisition unit 31 is activated by an instruction input via the input / output interface of the mobile terminal 3. The activated position information acquisition unit 31 starts receiving a positioning signal from the positioning satellite 21, acquires work machine position information indicating the position of the tractor 4 every second by a combination of latitude and longitude, and obtains the work machine position. Simultaneously with the acquisition of information, a position acquisition time that is an acquisition time of work implement position information is acquired. Thereafter, the position information acquisition unit 31 continuously acquires the work machine position information and the position acquisition time, and holds them in the position information table 300 shown in FIG. 3 in the acquired order (step S10: position information acquisition step).

As shown in FIG. 4, the tractor 4 on which the worker carrying the mobile terminal 3 gets off leaves the farm 5 at the position acquisition time “Apr 2 13:00:10 2012” in the position information table 300, and Go to 8A). When the tractor 4 arrives at the field 8A, the fertilizer application amount is set by the operation panel of the fertilizer application device 97, and the tractor 4 enters the field 8A. The tractor 4 starts the fertilizer application by starting the operation of the fertilizer spreading device 97 in the field 8A and starting the traveling in the field 8A (step S11).

At this time, the work information acquisition unit 43 of the tractor 4 acquires the fertilizer application amount output on the vehicle communication network of the tractor 4 from the fertilizer application device 97, and the vehicle speed and PTO rotation when the fertilizer application amount is acquired. The number and the like are acquired from the control unit 41 of the tractor 4 as work information. Further, the work information acquisition unit 43 acquires the time when the work information is acquired from the time measuring unit 42 as the work information acquisition time. Thereafter, until the operation of the fertilizer spreader 97 is stopped and the fertilization is finished, the work information acquisition unit 43 continuously acquires the work information and the work information acquisition time, and the work information table shown in FIG. 400 (step S12: work information acquisition step).

When the application of the fertilizer application device 97 is stopped after fertilization in the field 8A, the work information acquisition unit 43 stops acquiring the work information and the work information acquisition time, and the tractor 4 exits the field 8A. The tractor 4 that has left the field 8A stops at a point P shown in FIG. 4 and prepares for work in the next field 8B such as fertilizer replenishment. The position information acquisition unit 31 of the portable terminal 3 continuously acquires the work machine position information and the position acquisition time while the tractor 4 leaves the field 8A and prepares for work at the point P.

The tractor 4 ready for work enters the field 8B, operates the fertilizer spraying device 97, and starts fertilization. When the operation of the fertilizer application device 97 starts, the work information acquisition unit 43 continues the operation information and the operation information acquisition time until the operation of the fertilizer application device 97 stops and the fertilization ends by the same operation as step S12. Are stored in the work information table 400 shown in FIG.

When the tractor 4 finishes the farm work (fertilization) in the field 8B and returns to the farmer 5, the position information acquisition unit 31 of the portable terminal 3 receives the position from which the farmer 5 is departed as in the position information table 300 shown in FIG. The work equipment position information from the acquisition time “Apr 2 14:02:41 2012” back to the farmer 5 from the acquisition time “Apr 2 13:00:10 2012” is held as a trajectory of movement. . If the tractor 4 returns to the farmer 5, the position information acquisition unit 31 may be instructed to stop acquisition of work information and work information acquisition time via the input / output interface of the mobile terminal 3.

When the tractor 4 returns to the farmer 5, the work information acquisition unit 43 of the tractor 4 stores the work information of the tractor 4 in the farm field 8A and the work information of the tractor 4 in the farm field 8B as shown in the work information table 400 shown in FIG. Work information is held as a work history (step S13).
After the tractor 4 returns to the farm 5, the mobile terminal 3 acquires the work information table 400 of FIG. 5 from the work information acquisition unit 43 of the tractor 4. Thereafter, the portable terminal 3 uses the Wi-Fi or the like for the position information table 300 of FIG. 4 held in the position information acquisition unit 31 and the work information table 400 of FIG. 5 acquired from the work information acquisition unit 43 of the tractor 4. The information is output to the information processing terminal 7a provided in the farmer 5 by wireless communication connection or wired connection (step S14).

The performance information storage unit 71a of the information processing terminal 7a receives the position information table 300 and the work information table 400 output from the mobile terminal 3. At this time, the record information storage unit 71a associates the received position information table 300 with the work information table 400 based on the position acquisition time of the position information table 300 and the work information acquisition time of the work information table 400, and FIG. (Step S15: result information storing step).

Thereafter, the work place storage unit 73 of the information processing terminal 7a displays the stored farm field map of FIG. 3 on the display device of the information processing terminal 7a. The farm field 8A and the farm field 8B subjected to fertilization are designated on the displayed farm map using an input device such as a keyboard or a mouse (step S16: farm field designation process).
When the farm field 8A and the farm field 8B are designated on the farm map, the work place storage unit 73 obtains the latitude / longitude information (designated position) of the designated farm field 8A and the farm field 8B, and the designated work information extraction unit of the information processing terminal 7a. It outputs to 72a (step S17: agricultural field designation | designated process).

Then, work information associated with the detected work machine position is extracted, and an extraction work information table R1 for the farm field 8A and an extraction work information table R2 for the farm field 8B are acquired.

For example, when the work machine position corresponding to the latitude / longitude information (designated position) of the field 8A is detected in the result information table 500 of FIG. 8, the work information associated with the detected work machine position is extracted. Then, an extraction work information table R1 indicating the work machine position which is the latitude / longitude information of the field 8A and the work information at the work machine position is created. According to the extracted work information table R1, for example, the work information at the work machine position “latitude: 34.560269, longitude: 135.467894” is “vehicle speed: 1.50, PTO rotation speed: 318, fertilizer application amount: 0.08”.
