The working device 3 includes a working unit 40 that performs work and a frame 50 that supports the working unit 40. The frame 50 is connected to the vehicle body 4 via the connecting portion 7. The working device 3 is, for example, a tilling device that performs tilling. For the sake of convenience of explanation, the working device 3 will be described using a tillage device as an example. As a matter of course, the work device 3 is connected to the work vehicle 2 such as a device other than a tilling device, a fertilizer spraying device for spraying fertilizer, an agrochemical spraying device for spraying agricultural chemicals, a harvesting device for harvesting, a stand device, and the like.

The rotary shaft 58 is driven by the power transmitted to the chain transmission means. The rotating shaft 58 is rotated in the arrow A1 direction in FIG. When the rotating shaft 58 rotates in the A1 direction, the tilling claw 59 plows the soil and releases it to the rear rear part.

  As shown in FIG. 6, the work device 3 is provided with a wireless tag, that is, an RFID tag (Radio Frequency Identification) 10. The RFID tag 10 is a passive RFID tag that transmits at least identification information of the work device 3. The identification information is information for specifying, that is, identifying the work device 3. The identification information may be anything as long as it is information for identifying the work device 3, may be a unique number (serial number) assigned to each work device 3, or the model and model number of the work device 3. Information including the model may be used.

  The work vehicle 2 is provided with a wireless tag reader that receives identification information of the RFID tag 10, that is, an RFID reader 11. The direction (transmission direction) of the radio wave (signal) transmitted from the RFID reader 11 is directed to the work device 3, and the RFID tag 10 receives the radio wave transmitted from the RFID reader 11 and sends the identification information to the RFID reader. 11 can be transmitted.

A horizontal mounting position of the RFID tag 10 will be described.
The horizontal attachment position of the RFID tag 10 is determined by the horizontal position of the work device 3, the work vehicle 2, and the RFID reader 11. FIG. 4A is a plan view showing a positional relationship in the horizontal direction in the work device 3, the work vehicle 2, and the RFID reader 11. In FIG. 4A, the RFID reader 11 is provided at the rear portion of the cabin 9, but the present invention is not limited to this, and the attachment position of the RFID reader 11 is arbitrary.

  As shown in FIG. 4A, in a state where the work device 3 is connected to the work vehicle 2, a range extending toward the work device 3, that is, the frame 50 or the work unit 40 with the RFID reader 11 as a center is referred to as a “horizontal communication range J1”. And The center of the RFID reader 11 is the center position of the antenna that transmits radio waves. In other words, in the RFID reader 11, the range of radio waves transmitted from the antenna is set in advance, and is set at a predetermined angle with respect to the antenna. In this embodiment, the opening angle (transmission angle) is set to approximately 90 degrees with respect to the antenna. Accordingly, the horizontal communication range J1 is a range between one line L1 extending from the center of the antenna toward the work device 3 and the other line L2 extending from the center of the antenna toward the work device 3.

  When attention is paid to the work device 3 in a state where the work device 3 is mounted on the work vehicle 2, a horizontal range in which the work vehicle 2 overlaps in the width direction is defined as a “horizontal overlap range K1”. First, as shown in FIG. 4A, in the working device 3, a portion (for example, a transmission case 53) that protrudes from the most (left side) and a portion (for example, the side frame 54) that protrudes from the other (right side). When the space is “device range S1”, the horizontal overlap range K1 is a range of a portion of the device range S1 that overlaps the work vehicle 2.

  Specifically, in FIG. 4A, one line L3 extending toward the work device 3 from a portion (for example, the fender 31) that protrudes most from the left side of the vehicle body 4 of the work vehicle 2 and the work vehicle 2 A vehicle range T1 that is a range between the portion of the vehicle body 4 that protrudes from the othermost (right side) (for example, the fender 31) and the other line L4 extending toward the work device 3, is smaller than the device range S1. Since the entire device range T1 is included in the device range S1, the horizontal overlap range K1 is the same as the vehicle range T1.

  The RFID tag 10 is attached to a range (first attachment range) U1 including the horizontal overlap range K1 in the horizontal communication range J1. That is, the RFID tag 10 is attached to the frame 50 or the working unit 40 included in the first attachment range U1. In the case of FIG. 4A, for example, the RFID tag 10 is attached to the mast 56, the gear case 51, the support arm 52L and the support arm 52R included in the attachment range U1, the upper cover 57F included in the attachment range U1, and the like. It is possible.

Next, the mounting position of the RFID tag 10 in the vertical direction will be described.
The vertical mounting position of the RFID tag 10 is determined by the vertical positions of the work device 3, the work vehicle 2, and the RFID reader 11 as in the horizontal direction. FIG. 4B is a side view showing a vertical positional relationship in the work device 3, the work vehicle 2, and the RFID reader 11. In FIG. 4B, the RFID reader 11 is provided at the rear portion of the cabin 9, but is not limited to this, and the attachment position of the RFID reader 11 is arbitrary.

  As shown in FIG. 4B, in a state where the work device 3 is connected to the work vehicle 2, a range extending toward the work device 3, that is, the frame 50 or the work unit 40 around the RFID reader 11 is referred to as “vertical communication range J 2”. And The range of the vertical communication range J2 is set to approximately 90 degrees with the antenna as the center, as in the horizontal direction. Accordingly, the vertical communication range J2 is a range between one line N1 extending from the center of the antenna toward the work device 3 and the other line N2 extending from the center of the antenna toward the work device 3.

  When attention is paid to the work device 3 in a state where the work device 3 is mounted on the work vehicle 2, a vertical range in which the work vehicles 2 overlap is defined as a “vertical overlap range K <b> 2”. First, as shown in FIG. 4B, in the work device 3, a portion between the most protruding portion (for example, the mast 56) and the most protruding portion (for example, the tilling nail 59) from the other (lower portion). Is “device range S2”, the vertical overlap range K2 is a range of a portion of the device range S2 that overlaps the work vehicle 2.

  In FIG. 4B, one line N3 extending toward the work device 3 from a portion (for example, the upper end of the cabin 9) that protrudes most from the upper side (the upper side) of the vehicle body 4 of the work vehicle 2 and the vehicle body 4 of the work vehicle 2 are shown. The vehicle range T2 that is the range between the portion that protrudes most from the other (lower part) (for example, the lower end of the rear wheel 30R) and the other line N4 that extends toward the work device 3, is larger than the device range S2. Since the device range S2 is included in all the vehicle ranges T2, the direct overlap range K2 is the same as the device range S2.

  The RFID tag 10 is attached to a range (second attachment range) U2 including the vertical overlap range K2 in the vertical communication range J2. That is, the RFID tag 10 is attached to the frame 50 or the working unit 40 included in the second attachment range U2. In the case of FIG. 4B, the RFID tag 10 includes a mast 56, a gear case 51, a support arm 52L, a support arm 52R, a portion included in the mounting range U2 of the upper cover 57F, a portion included in the mounting range U2 of the rear cover 57R, and the like. It is possible to install on.

  As described above, according to the work device 3, the RFID tag 10 is in a range that overlaps the vehicle body 4 in the horizontal direction in the frame 50, and extends horizontally toward the frame 50 around the RFID reader 11 that receives the identification information of the RFID tag 10. It is attached to the first attachment range U1 that overlaps the communication range J1. Therefore, since the RFID tag 10 is positioned in the first attachment range U1 that overlaps the work vehicle 2 in the communication range in the horizontal direction of the RFID reader 11, the RFID tag 10 is located with respect to the RFID reader 11. Identification information can be transmitted stably.

  According to the work device 3, the RFID tag 10 is a range that overlaps the vehicle body 4 in the frame 50 in the vertical direction, and that extends to the frame 50 side around the RFID reader 11 that receives the identification information of the RFID tag 10. It is attached to the second attachment range U2 overlapping with J2. Therefore, since the RFID tag 10 is located in the second attachment range U2 that overlaps the work vehicle 2 in the communication range in the vertical direction of the RFID reader 11, the RFID tag 10 is located with respect to the RFID reader 11. Identification information can be transmitted stably.

That is, the attachment position for attaching the RFID tag 10 to the work device 3 is set based not only on the relationship with the RFID reader 11 but also on the relationship between the work vehicle 2 and the work device 3. The identification information from the working device 3 can be acquired even when the work is performed while operating each of the three.
The RFID tag 10 is attached to the work device 3 in a range that satisfies the first attachment range U1 and the second attachment range U2. In addition, the communication distance between the RFID tag 10 and the RFID reader 11 is considered. It is preferable. For example, when the front-rear width or the machine body width of the work device 3 is small and the communication distance is sufficiently large with respect to the first attachment range U1 and the second attachment range U2, the longest distance of the first attachment range U1 and the second attachment range U2 < For the communication distance), the RFID tag 10 is attached to the first attachment range U1 and the second attachment range U2. On the other hand, when the front-rear width or the machine body width of the work device 3 is large and the communication distance is small with respect to the first attachment range U1 and the second attachment range U2, the longest distance between the first attachment range U1 and the second attachment range U2> communication For the distance), the RFID tag 10 is attached at a position that does not exceed the communication distance in the first attachment range U1 and the second attachment range U2.

A horizontal mounting position of the RFID reader 11 will be described.
The horizontal attachment position of the RFID reader 11 is determined by the horizontal position of the work device 3, the work vehicle 2, and the RFID tag 10.
FIG. 5A is a plan view showing a positional relationship in the horizontal direction in the work device 3, the work vehicle 2, and the RFID tag 10. In FIG. 5A, the RFID tag 10 is provided in the gear case 51, but the present invention is not limited to this, and the attachment position of the RFID tag 10 is arbitrary.

  As shown in FIG. 5A, in a state where the work device 3 is connected to the work vehicle 2, a range extending toward the work vehicle 2, that is, the vehicle body 4 around the RFID tag 10 is defined as a “horizontal communication range J3”. The center of the RFID tag 10 is the center position of the antenna that transmits radio waves. In other words, in the RFID tag 10, the range of radio waves transmitted from the antenna is set in advance, and is set at a predetermined angle with the antenna as the center. In this embodiment, the opening angle (transmission angle) about the antenna is set to approximately 90 degrees. Accordingly, the horizontal communication range J3 is a range between one line L7 extending from the center of the antenna toward the work device 3 and the other line L8 extending from the center of the antenna toward the work device 3.

  When attention is paid to the work vehicle 2 with the work device 3 mounted on the work vehicle 2, a horizontal range in which the work device 3 overlaps in the width direction is defined as a “horizontal overlap range K3”. The horizontal overlap range K3 is a portion of the vehicle range T1 of the work vehicle 2 that overlaps with the device range S1 of the work device 3. Since the device range S1 is larger than the vehicle range T1, the horizontal overlap range K3 is the same as the vehicle range T1.

  The RFID reader 11 is attached to a range (third attachment range) U3 including the horizontal overlap range K3 in the horizontal communication range J3. That is, the RFID reader 11 is attached to the third attachment range U3 including the horizontal overlap range K3 in the vehicle body 4 or the connecting portion 7. In the case of FIG. 5A, the RFID reader 11 can be attached to the cabin 9, the fender 31, and the like.

Next, the vertical mounting position of the RFID reader 11 will be described.
The vertical mounting position of the RFID reader 11 is determined by the vertical positions of the work device 3, the work vehicle 2, and the RFID tag 10 as in the horizontal direction.
FIG. 5B is a side view showing the positional relationship in the vertical direction in the work device 3, the work vehicle 2, and the RFID tag 10. As shown in FIG. 5B, in a state where the work device 3 is connected to the work vehicle 2, a range extending toward the work vehicle 2, that is, the vehicle body 4 around the RFID tag 10 is defined as a “vertical communication range J4”. The range of the vertical communication range J4 is set to approximately 90 degrees with the antenna as the center, as in the horizontal direction. Therefore, the vertical communication range J4 is a range between one line N5 extending from the center of the antenna toward the work vehicle 2 and the other line N6 extending from the center of the antenna toward the work vehicle 2.

  Further, when attention is paid to the work vehicle 2 in a state where the work device 3 is mounted on the work vehicle 2, a vertical range in which the work devices 3 overlap is defined as a “vertical overlap range K4”. First, as illustrated in FIG. 5B, the vertical overlap range K <b> 4 is a portion that overlaps the device range S <b> 2 of the work device 3 in the vehicle range T <b> 2 of the work vehicle 2. Since the device range S2 is smaller than the vehicle range T2, the horizontal overlap range K4 is a portion overlapping the device range S2.

  The RFID reader 11 is attached to a range (fourth attachment range) U4 including the vertical overlap range K4 in the vertical communication range J4. That is, the RFID reader 11 is attached to the fourth attachment range U4 including the horizontal overlap range K3 in the vehicle body 4 or the connecting portion 7. In the case of FIG. 5B, the RFID reader 11 can be attached to a part of the fender 31 and the cabin 6 included in the attachment range U4.

  As described above, according to the work vehicle 2, the RFID reader 11 is a range that overlaps with the work device 3 in the horizontal direction in the vehicle body 4, and that overlaps a horizontal communication range that spreads toward the vehicle body 4 around the RFID tag 10. It is attached to U3. Therefore, since the RFID reader 11 is located in the third attachment range U3 that overlaps the work device 3 in the communication range in the horizontal direction of the RFID tag 10, the identification information transmitted from the RFID tag 10 is displayed. The RFID reader 11 can receive stably.

  The RFID reader 11 is attached to a fourth attachment range U4 that overlaps the working device 3 in the vehicle body 4 in the vertical direction and overlaps the vertical communication range that extends toward the vehicle body 4 with the RFID tag 10 as the center. Therefore, since the RFID reader 11 is positioned in the fourth attachment range U4 that overlaps the work device 3 in the communication range in the vertical direction of the RFID tag 10, the identification information transmitted from the RFID tag 10 is displayed. The RFID reader 11 can receive stably.

That is, since the attachment position for attaching the RFID reader 11 to the work vehicle 2 is set based not only on the relationship with the RFID tag 10 but also on the relationship between the work vehicle 2 and the work device 3, the work vehicle 2 and the work device. The identification information from the working device 3 can be acquired even when the work is performed while operating each of the three.
The RFID reader 11 is attached to the work vehicle 2 in a range that satisfies the third attachment range U3 and the fourth attachment range U4. In addition, the communication distance between the RFID tag 10 and the RFID reader 11 is taken into consideration. It is preferable. For example, when the front-rear width or the body width of the work vehicle 3 is small and the communication distance is sufficiently larger than the third attachment range U3 and the fourth attachment range U4 (the longest distance between the third attachment range U3 and the fourth attachment range U4 < For the communication distance), the RFID reader 11 is attached to the third attachment range U3 and the fourth attachment range U4. On the other hand, when the front-rear width or the body width of the work vehicle 2 is large and the communication distance is small with respect to the third attachment range U3 and the fourth attachment range U4 (the longest distance between the third attachment range U3 and the fourth attachment range U4)> communication For the distance), the RFID reader 11 is attached at a position not exceeding the communication distance in the third attachment range U3 and the fourth attachment range U4.

In the above-described embodiment, the attachment position of the RFID tag 10 and the attachment position of the RFID reader 11 are described separately. However, the RFID tag 10 is attached so that both the conditions for attaching the RFID tag 10 and the attachment of the RFID reader 11 are satisfied. Each of the tag 10 and the RFID reader 11 may be attached, may be attached so as to satisfy the condition of only the RFID tag 10, or may be attached only of the condition of the RFID tag 10.
An RFID tag 10 is attached to the work device 3, and an RFID reader 11 is attached to the work vehicle 2. Therefore, the RFID reader 11 can acquire the identification information of the RFID tag 10 simply by bringing the working device 3 corresponding to the work close to the rear part of the work vehicle 2. For example, it is possible to easily grasp which work device 3 is attached to the work vehicle 2 by the identification information simply by driving the work vehicle 2 and bringing it closer to the work device 3 to be mounted. Further, even after the work device 3 is mounted on the work vehicle 2, the worker can check the work device 3 mounted on the work vehicle 2.

  As a matter of course, the types and shapes of the work vehicle 2 and the work device 3 are not limited as long as the conditions for attaching the RFID tag 10 and the case of attaching the RFID reader 11 are satisfied. For example, as shown in FIGS. 5C and 5D, the present invention can also be applied to a boom sprayer in which the work apparatus 3 has a large body width. The working device 3 includes a working unit 40 and a frame 50. The frame 50 is formed in a frame shape by vertical members 50a, cross members 50b, and the like. The working unit 40 includes a tank 40a for storing medicines and the like, and a nozzle 40b attached to a support member protruding left or right from the rear part of the frame 50.

Further, not only the identification information but also the operation information reaches the server via the communication device 12e mounted on the predetermined work vehicle 2. Therefore, it can be proved by the fact that the predetermined work vehicle 2 towed the predetermined work device 3 to perform the work with the fact that the identification information and the operation information corresponding to the identification information are stored in the server, The reliability of work results can be improved. In FIG. 8, the position detection unit 13c is provided in the mobile terminal 13, but instead, the communication device 12e may be provided with the same configuration as the position detection unit 13c. In this case, the communication device 12e also transmits position information when transmitting identification information and operation information to the mobile terminal 13. Further, the communication device 12e may transmit identification information, operation information, and position information to the server 15 through a mobile phone communication network or a data communication network.

If the identification information received by the RFID reader 11 and the position information detected by the position detection unit 13c are stored in any of the communication device 12e, the portable terminal 13, and the server 15, the RFID reader 11 receives the identification information. It is possible to grasp the position where the work device 3 is disconnected, that is, the position where the work device 3 is separated from the work vehicle 2.
