The spraying device 2 includes a container (hopper) 2a that can store (accommodate) the material to be sprayed, and a spreading mechanism 2b that is provided in the container 2a and that sprays the material in the container 2a to the outside. The scattering mechanism 2b is composed of, for example, a shutter that can be opened and closed, and can scatter the material to be sprayed by opening and closing the shutter. Note that the spraying device 2 is not limited to the device shown in FIG. 10, and may be, for example, the spraying device 2 shown in FIG. 9A, the spreading device 2b shown in FIG. 9B, or other spraying devices. It may be the device 2.

The spreading mechanism 2b of the spreading device 2 in FIG. 9A includes a feed roll 2b1 that is attached to the lower part of the container 2a and feeds out the material to be sprayed from the container 2a, and a hose 2b2 that spreads the material fed from the feed roll 2b1 to the lower part. have. The case accommodating the container 2a, the feed roll 2b1, and the hose 2b2 are supported by a frame 2b3, and by connecting the frame 2b3 to the connecting portion 8, the spraying device 2 is mounted on the tractor 1.

The spraying device 2 shown in FIG. 9B has a plurality of containers 2a that can accommodate at least two types of spray materials. The plurality of containers 2a include a plurality of first containers two a1 arranged at the front and a plurality of second containers two a2 arranged at the rear. Fertilizer is stored in the plurality of first containers two a1 as a spray material, and seeds are stored as a spray material in the plurality of second containers two a2. The spreading mechanism 2b includes a feed roll 2b5 that feeds out fertilizer, a hose 2b6 that spreads the fertilizer fed from the feed roll 2b5 to the lower part, a feed roll 2b7 that feeds out seeds, and a feed roll 2b7 that spreads the seeds fed from the feed roll 2b7 to the bottom.

It will be installed. Note that the spraying device 2 in FIG. 9B may include a disk 2b10 and a suppression wheel 2b11.

As shown in FIG. 1, the spraying device 2 includes a control device 2c that controls the spraying mechanism 2b, and a display device 2d connected to the control device 2c. The display device 2d displays information such as per predetermined area (spraying amount per unit area [for example, 10 kg/10a (1000 m ² )], spreading width of the spray material (unit: m), amount of the spray material put into the container 2a ( Unit: kg), etc. can be input.The control device 2c controls the opening/closing amount (opening degree), opening/closing timing, etc. of the spreading mechanism 2b based on the spreading amount, spreading width, etc. It is preferable that the spraying is performed in conjunction with the vehicle speed to change the amount of spraying per unit time in conjunction with the moving speed (vehicle speed).In addition, the control device 2c controls the display device 2d by operating a switch or the like provided on the display device 2d. When the spraying starts, a signal (start signal) indicating that the spraying has started is output to the in-vehicle network N1, which will be described later.Furthermore, when a switch or the like is operated and the spraying ends, the control device 2c outputs a signal indicating that the spraying has started. A signal (end signal) indicating this is output to the in-vehicle network N1.

Further, the spraying device 2 includes a remaining amount detection device 2e that detects the remaining amount of the spray material in the container 2a. The remaining amount detection device 2e is composed of a sensor, a load cell, etc., and detects the weight of the spray material contained in the container 2a as the remaining amount. The remaining amount detected by the remaining amount detection device 2e is output to the in-vehicle network N1. The remaining amount detection device 2e may determine the remaining amount by detecting the height (bulk) of the material to be sprayed in the container 2a with a sensor and estimating the weight of the material to be sprayed based on the detected volume. The remaining amount may be a value obtained by subtracting the amount of the material actually sprayed from the amount of material input.

As shown in FIG. 1, the tractor 1 includes a detection device 10, a control device 11, a display device 12, and a communication device 13. The detection device 10, the control device 11, and the display device 12 are connected by an in-vehicle network N1 such as CAN.
The detection device 10 is a device that detects the traveling state in which the tractor 1 is traveling (the traveling state of the traveling vehicle body 3). The detection device 10 can detect, for example, the moving distance and moving speed (vehicle speed) of the running vehicle body 3 as the running state. In this embodiment, the detection device 10 uses a satellite positioning system (Global Positioning System, Galileo, GLONASS, etc.) to calculate the position of the traveling vehicle body 3, and detects the moving distance and moving speed from the calculated position.

The detection device 10 includes a receiving section 10a that receives a satellite signal (radio wave) from a positioning satellite 15, and a state calculation section 10b that calculates the running state of the tractor 1 (traveling vehicle body 3) based on the satellite signal received by the receiving section 10a. It has The receiving section 10a and the state calculating section 10b are composed of electrical/electronic parts, programs installed in a CPU, etc. As shown in FIG. 10, the detection device 10 includes a housing 10c that houses a receiving section 10a and a state calculating section 10b. The housing 10c is attached to the top plate of the cabin 7. Note that the housing 10c may be attached to a location other than the cabin 7, and may be provided to the working device 2, for example.

The state calculating section 10b calculates the position of the receiving section 10a based on the carrier phase of the satellite signal transmitted from the positioning satellite 15. Then, the state calculation unit 10b calculates the moving distance when the receiving unit 10a changes position within a predetermined time, converts the moving distance into a speed, and sets the converted value as the moving speed (vehicle speed) of the tractor 1. Note that the status calculation unit 10b calculates the difference (Doppler shift value) between the frequency of the satellite signal transmitted by the positioning satellite 15 and the frequency of the satellite signal when the reception unit 10a receives the satellite signal, and based on the satellite signal. The position of the receiving unit 10a may be calculated, and the method of calculating the position is not limited. Further, the state calculation unit 10b may calculate only the moving distance or only the moving speed (vehicle speed). Travel information regarding the travel of the traveling vehicle body 3, including the travel distance and travel speed calculated by the state calculation unit 10b, is output to the in-vehicle network N1. Therefore, the travel information (traveling distance, traveling speed) can be acquired by the control device 11, the display device 12, and the like.

The control device 11 receives operation signals when operating tools (operation levers, operation switches, operation volume, etc.) installed around the driver's seat 6, detection signals from various sensors mounted on the traveling vehicle body 3, etc. Based on this, the driving system and work system of the tractor 1 are controlled. For example, the control device 11 controls the connection portion 8 to move up and down based on an operation signal from an operating tool, or controls the rotation speed of the diesel engine based on an accelerator pedal sensor. Note that the control device 11 may be any device that controls the working system and traveling system of the tractor 1, and the control system is not limited.

The display device 12 can display various information. The display device 12 displays the position of the traveling vehicle body 3 (the position of the tractor 1), that is, the traveling trajectory W1. As shown in FIG. 2, when a predetermined operation is performed, the display device 12 displays a running screen M1. The driving screen M1 includes a field display section 30 and a direction display section 31. The field display section 30 is an area that virtually represents a workplace such as a farm field, and is assigned latitude, longitude, and the like. A machine display section 33 is shown in the field display section 30 . The machine display section 33 virtually shows the tractor 1 (traveling vehicle body 3), and the display position of the machine display section 33 with respect to the field display section 30 is fixed. Further, the boundary line P1 of the machine display section 33 is the current position of the tractor 1 (traveling vehicle body 3) in the field display section 30.

Therefore, when the tractor 1 is actually driven, the display position of the machine display section 33 shown on the field display section 30 remains fixed, and as the position of the traveling vehicle body 3 detected by the detection device 10 changes, While the field display section 30 scrolls, the area behind the boundary line P1 of the machine display section 33 is colored in the field display section 30, so that the travel trajectory W1 is continuously displayed on the field display section 30.

The direction display section 31 is a section that indicates how far the tractor 1 is deviated from a predetermined position by the amount of deviation. For example, if the current position of the tractor 1 is deviated by 0.5 m from the predetermined reference line L1, the direction display section 31 will indicate 0.5 m as the amount of deviation, and the tractor 1 will be deviated from the reference line L1 by 0.5 m. The direction of deviation is indicated by an arrow, etc.
The communication device 13 is configured with a device that performs short-range or long-distance communication, and can be connected to external equipment. For example, the communication device 13 is a device that performs wireless communication using Wi-Fi (Wireless Fidelity, a registered trademark) of the IEEE802.11 series, which is a communication standard. Note that the communication device 13 may be a device that performs wireless communication using a mobile phone communication network or a device that performs wireless communication using a data communication network.

As shown in FIG. 1, the dispersion support system includes a server 50, a first terminal 51, and a second terminal 52. The server 50 is a server that manages work plans, and the first terminal 51 and the second terminal 52 are terminals that can be connected to the server 50. The first terminal 51 is a personal computer (PC) or the like assigned to an administrator. The second terminal 52 is operable by a farm worker who performs farm work such as spraying work, and is a mobile terminal such as a smartphone, tablet, or PDA that is assigned to the farm worker and carried by the farm worker.

The server 50 includes a work plan creation section 60 that creates a work plan, and a work plan storage section 61 that stores the work plan. The work plan creation unit 60 is composed of programs and the like stored in the server 50. The work plan is a plan regarding agricultural work to be performed in the field, and includes at least spraying work to be performed in the field as agricultural work. The spraying work includes, for example, the work of spreading fertilizer (fertilization work), the work of spraying pesticides (pesticide spraying work), the sowing work of sowing seeds, and the like. In addition, in agricultural work, work related to spraying may be considered to be spraying work. In addition, the server 50 can set plans for agricultural work, such as soil preparation, ridge coating, plowing, rice planting, plowing, furrowing, weeding, harvesting, sowing, fertilization (fertilization work), and chemical spraying. be.

When the first terminal 51 logs into the server 50 and receives a request to create a work plan from the first terminal 51, the work plan creation unit 60 creates a work plan in response to this request, as shown in FIG. A planning screen M2 for making a plan is displayed on the first terminal 51.
The planning screen M2 includes a date setting section 80 for setting the date for agricultural work, a workplace setting section 81 for setting a workplace such as a field, a work setting section 82 for setting agricultural work (work items of agricultural work), and a work setting section 82 for setting agricultural work (work items of agricultural work). It includes a worker setting section 83 for setting, and a time setting section 84 for setting work time. The planning screen M2 also includes a machine setting section 85 for setting the machine, a spray setting section 86 for setting the type of spray material, and a spray amount setting section 87 for setting the spray amount of the spray material.

A map of the workplace is displayed in the workplace setting section 81, and by selecting a workplace shown on the map, a workplace where work is to be performed can be set. The work setting unit 82 is configured to set work items for the various agricultural works described above (soil making, ridge coating, plowing, rice planting, puddling, furrowing, weeding, harvesting, sowing, fertilization (fertilization work), chemical spraying), that is, work items. can be selected or input.

In the worker setting section 83, worker names (agricultural worker names) registered in advance in the first terminal 51 or the server 50 are displayed in a list, and the worker is determined by selecting the name of the worker who will perform the work from the list. can do. In addition, the time setting section 84 can set the time slot for agricultural work. In the machine setting section 85, it is possible to set a working device when working with an agricultural machine. In the spray material setting section 86, the type of spray material used for seeding, fertilization, chemical spraying, etc. can be set. In the spray amount setting section 87, the spray amount of the spray material per predetermined area can be set. The work plan set on the planning screen M2 [date, work place, work item (work content), worker name, work time, machine (work device), type of material to be spread, amount of spread] is stored in the work plan storage unit 61. Make me remember.

Therefore, by connecting the first terminal 51 to the server 50, a work plan can be easily created in association with a farm worker, and the created work plan can be stored in the work plan storage section 61.
The server 50 also includes a work instruction section 63. The work instruction section 63 is composed of programs and the like stored in the server 50. The work instruction unit 63 can transmit a work plan to the second terminal 52.

When the second terminal 52 assigned to a farm worker logs into the server 50 and receives a request from the second terminal 52 to send a work plan, the work instruction unit 63 transmits the request to the second terminal 52 in response to this request. The work plan including the worker assigned to is extracted from the work plan storage unit 61. Then, the work instruction unit 63 transmits the extracted work plan to the second terminal 52. In addition, input the field for which you want to obtain a work plan into the second terminal 52, request the server 50 for the field for which you want to obtain the work plan from the second terminal 52, and the server 50 (work instruction unit 63) A work plan corresponding to the above may be transmitted to the second terminal 52.

The second terminal 52 can display the work plan acquired from the server 50 and can transmit it to the agricultural machine 1 such as a tractor. The second terminal 52 includes a communication section 52a, a storage section 52b, and a display section 52c.
The communication unit 52a is a device that performs wireless communication with the communication device 13 and the server 50. The communication unit 52a can perform wireless communication using, for example, Wi-Fi (Wireless Fidelity, a registered trademark) of the IEEE802.11 series of communication standards. Further, the communication unit 52a can perform wireless communication using, for example, a mobile phone communication network, a data communication network, a mobile phone communication network, or the like. Therefore, by connecting the second terminal 52 to the server 50, the communication unit 52a can receive the work plan stored in the work plan storage unit 61 of the server 50. Further, the work plan received by the communication unit 52a can be transmitted to the communication device 13 of the tractor 1. The storage unit 52b can store various information such as work plans. The display unit 52c can display various information such as work plans.

Now, the display device 12 mounted on the tractor 1 can display the possible range in which the material to be sprayed can be spread. The possible range includes, for example, the travel distance that can be covered by the tractor 1 from the present moment (spraying possible distance), the time that can be sprayed (spraying possible time), and the area that can be sprayed (spraying possible distance). possible area) etc. All of the sprayable distance, sprayable time, and sprayable area are determined based on the remaining amount of the spray material that can be obtained from the working device (spreading device) 2.

As shown in FIG. 1, the spraying support system includes a travel information acquisition section 69, a remaining amount acquisition section 70, and a work calculation section 71. The traveling information acquisition section 69, the remaining amount acquisition section 70, and the work calculation section 71 are configured to operate on an electric/electronic circuit provided in the control device 11, a program stored in the control device 11, an electric/electronic circuit provided in the display device 12, and a display. These include programs stored in the device 12. In this embodiment, the description will proceed assuming that the travel information acquisition section 69, the remaining amount acquisition section 70, and the work calculation section 71 are provided in the display device 12.

The traveling information acquisition section 69 acquires traveling information regarding the traveling of the traveling vehicle body, and acquires the vehicle speed calculated by the state calculation section 10b of the detection device 10. For example, when the running vehicle body 3 starts running, the state calculation unit 10b of the detection device 10 outputs the calculated vehicle speed to the in-vehicle network N1. The driving information acquisition unit 69 sequentially acquires the vehicle speed output to the in-vehicle network N1.
The remaining amount obtaining unit 70 obtains the remaining amount of the spray material from the spreading device 2 . For example, in the spraying device 2, when spraying is started, the remaining amount acquisition unit 70 acquires the weight of the spray material remaining in the container 2a at predetermined intervals, that is, the remaining amount. That is, when the spraying operation by the spraying device 2 is started, the control device 2c outputs the remaining amount to the in-vehicle network N1. On the other hand, the remaining amount acquisition unit 70 acquires the remaining amount outputted to the in-vehicle network N1 when the spreading operation by the spreading device 2 is started.

The work calculation unit 71 calculates a possible range (sprayable distance, sprayable time, sprayable area) based on the remaining amount acquired by the remaining amount acquisition unit 70. When calculating the possible spraying time, the work calculation unit 71 calculates the spraying amount per second by, for example, the product of the vehicle speed of the traveling vehicle body 3 per second, the spraying width, and the spraying amount. Amount (kg/sec) = Vehicle speed (m/sec) x Spreading width (m) x Spreading amount per unit area (kg/m ² ).

Here, the spreading width can be obtained by the machine (work device) indicated in the work plan. That is, the work calculation unit 71 refers to the machine (work device) indicated in the work plan acquired by the communication device 13 and calculates the spreading width from the machine. The machine and the spreading width are determined in advance, and the relationship between the machine and the spreading width is stored in the display device 12 or the like in advance. In addition, in the work plan, the spreading width may be set so that the spreading width indicated in the work plan may be used, or the work calculating section 71 may request the working width to the control device 2c of the working device 2. It may also be acquired from the control device 2c.

The amount of application per unit area can be obtained by the amount of application indicated in the work plan. That is, the work calculation unit 71 refers to the application amount indicated in the work plan acquired by the communication device 13, and applies the referenced application amount to the application amount per unit area. The vehicle speed is the vehicle speed detected by the detection device 10 (state calculation unit 10a).
After determining the amount of spraying per second, the work calculation unit 71 calculates the possible spraying time by dividing the amount of spraying per second from the remaining amount acquired by the remaining amount acquiring unit 70. Further, when calculating the possible spraying distance, the work calculation unit 71 calculates the possible spraying distance by multiplying the vehicle speed and the possible spraying time. Further, when calculating the sprayable area, the work calculation unit 71 calculates the sprayable area by dividing the spray amount per unit area from the remaining amount.

FIG. 4 is a diagram summarizing the operational flow from creating a work plan to determining the possible range (sprayable distance, sprayable time, sprayable area).
As shown in FIG. 4, when a work plan is created by the work plan creation unit 60 of the server 50 (S1), the created work plan is transmitted to a predetermined second terminal 52 by the work instruction unit 63 (S2). . When the second terminal 52 acquires the work plan, the second terminal 52 transmits the acquired work plan to the communication device 13 of the tractor 1 (S3). When calculating the possible range, the work calculation unit 71 determines the field where the spraying work is to be performed based on the position of the tractor 1 detected by the detection device 10 (S4). For example, the work calculation unit 71 sets the field where the tractor 1 is currently located as the field where the spraying work is to be performed. The work calculation unit 71 refers to the work plan corresponding to the determined field among the work plans received by the communication device 13 (S5). Based on the information on the work plan, for example, the machine and the amount of spraying shown in the work plan, and the vehicle speed of the tractor 1 detected by the detection device 10, the possible range (spraying distance, possible spraying distance, etc.) is determined by the method described above. time, sprayable area) are determined (S6).

The display device 12 displays the possible range (sprayable distance, sprayable time, sprayable area). The display device 12 displays, for example, the possible range (sprayable distance, sprayable time, sprayable area) on the driving screen M1.
As shown in FIGS. 5A to 5C, the travel screen M1 includes a work display section 89 that displays a possible range. As shown in FIG. 5A, the work display section 89 displays, for example, 761 m as the possible spraying distance. Further, the work display section 89 displays the number of round trips that can be made from the current location (number of round trips). In this case, the work calculation unit 71 calculates the number of reciprocations that can be made from the length of the field (length of one side) or the straight travel length (straight travel distance) L2 of the vehicle 3 (number of reciprocations = possible spraying distance ÷ (2 x field length, number of round trips = possible spraying distance ÷ (2 x straight distance L2)). It can be obtained by making an inquiry to the server 50 via the device 13 or the like.As shown in FIG. In other words, the straight distance L2 can be obtained from the position of the tractor 1 detected by the detection device 10.

As described above, the display device 12 displays the number of round trips determined by the work calculation unit 71 together with the possible spraying distance.
As shown in FIG. 5B, the work display section 89 displays, for example, 8.4 squares as the sprayable area. Further, the work display section 89 displays whether or not the spraying work is completed in the field from the current point. In this case, as shown in FIG. 6, the work calculation unit 71 calculates the spraying area according to the following formula: spraying completed area = number of straight-line operations to date (number of straight lines) n (pieces) x work width W2 (m) x straight-line distance L2 (m). The remaining sprayed area is determined by determining the completed area (S) and subtracting the sprayed area from the field area . The work calculation unit 71 determines that the spraying work is completed when the sprayable area≧the remaining spraying area, and determines that the spraying work is not completed when the sprayable area<the remaining spraying area. The display device 12 displays the determination result of the work calculation unit 71 on the work display unit 89 of the travel screen M1.

As shown in FIG. 5C, the work display section 89 displays 1095 seconds as the possible spraying time. Further, the work display section 89 displays the time after the elapse of the possible spraying time from the current time. Note that the current time is the time obtained from the signal detected by the detection device 10 (time obtained from the positioning satellite), or the time calculated by the time measurement section built in the control device 11 and the display device 12. .

In the embodiment described above, the display device 12 displays the sprayable distance, sprayable time, and sprayable area on the work display section 89, but it is sufficient to display at least one of them.
FIG. 7 shows a modification of the possible range display on the display device 12. As shown in FIG. 7, the display device 12 displays a spraying status screen M3 when the spraying work is started. On the spraying status screen M3, a graphic 90 imitating the container 2a of the spraying device 2 is displayed, and the remaining amount of the material to be sprayed is displayed in multiple levels within the graphic 90. FIG. 7 shows the remaining amount in seven levels (level 1 to level 7), where level 1 is the lowest remaining amount and level 7 is the highest remaining amount.

The spraying status screen M3 displays the name of the machine used in the spraying work, etc., as well as all of the spraying width, sprayable distance, sprayable time, and sprayable area.
FIG. 8 shows a modification of the display of the possible range on the display device 12. As shown in FIG. 8, the display device 12 displays a spraying status screen M4 when the spraying work is started. The spraying status screen M4 is a screen when the spraying device 2 has a plurality of containers 2a.
