Description

Technical Field

[0001] The present invention relates to a monitoring system for a speed sprayer that displays video data captured by a camera unit of the view around a vehicle on a monitor screen of a monitor unit.

Background Art

[0002] Generally, a speed sprayer for spraying a chemical solution in a field such as an orchard is known. This type of speed sprayer has a driver's seat at the front of the vehicle and a chemical solution tank and a spraying mechanism for spraying the chemical solution in the chemical solution tank outward behind the driver's seat. Further, since the speed sprayer travels on a rough road including uneven roads between a large number of fruit trees in the field, it is not uncommon for the vehicle to travel in an unstable state or collide with branches of fruit trees. Therefore, appropriately checking the state and view around the speed sprayer is important from the viewpoints of smooth spraying work and safety. Usually, the speed sprayer is provided with confirmation means using a mirror body for checking the state and situation around it, such as side mirrors and rear mirrors.

[0003] Conventionally, as speed sprayers provided with such confirmation means, a speed sprayer described in Patent Document 1 and a rear mirror device of a speed sprayer described in Patent Document 2 are known.

[0004] The speed sprayer described in Patent Document 1 aims to provide a speed sprayer that allows the driver to visually check the degree of rear wheel lock and the distance between the rear wheel and an obstacle, as well as to visually check obstacles in the direction of the turning center and enable turning. Specifically, the speed sprayer has a cabin at the very front with a driver's seat and a rear view window, and a chemical tank with a downward-sloping recess formed at the very front of its upper surface is positioned immediately behind the cabin, and a rearview mirror and side mirrors are arranged inside the cabin and on the left and right outer front sides. In this speed sprayer, the position and size of the rear view window are set so that the rear wheel and its contact point with the ground can be visually checked, as well as the upper part of the rear wheel can be visually checked, and the dimensions and shape of the chemical tank, including the recess, and the height of its uppermost surface are set.

[0005] Furthermore, the rearview mirror device described in Patent Document 2 is for a speed sprayer without a cabin with an open driver's seat, and aims to easily store the rearview mirror in a storage position that does not protrude from the outer surface of the hood, and to easily obtain a desired storage configuration. Specifically, the mirror arm is mounted on the mounting surface of the hood so as to be rotatable and so as to be able to stop in a usage position in which the rearview mirror can be used and in a storage position in which the rearview mirror is in contact with or close to the hood, and the mounting surface is set at a predetermined angle with respect to the horizontal plane so that the rearview mirror in the storage position is approximately parallel to the outer surface of the hood.

[0007] However, the conventional speed sprayer and rearview mirror devices described above also had the following problems that needed to be addressed.

[0008] Firstly, even if it is possible to some extent to grasp the surrounding conditions of the vehicle, there is no means to accurately check the conditions specific to the speed sprayer, namely the spraying conditions. For example, the understanding is limited to an inappropriate or narrow range, and in some situations the operator has to turn around to check, making it difficult to easily and adequately check the actual spraying conditions.

[0009] Secondly, because the system primarily relied on placing optical mirrors in specific locations, it was insufficient in terms of ensuring the necessary field of view. In particular, because mirrors needed to be placed in many different locations depending on their purpose, checking required turning towards each individual mirror, which was inconvenient. Furthermore, for operators who were also driving, it was difficult to concentrate on driving, thus compromising safety.

[0010] The present invention aims to provide a monitoring system for speed sprayers that solves the problems present in the background technology described above. [Means for solving the problem]

[0011] The monitoring system 1 for a speed sprayer M according to the present invention solves the above-mentioned problems and is a monitoring system that has a monitoring function that displays video data captured by a camera unit 2 of the view around the vehicle 50 on a monitor screen Vm of a monitor unit 3 installed on or near the dashboard of the driver's seat 51, and is characterized by comprising: a camera unit 2 having a spray state capturing camera 2a installed at a predetermined position on the vehicle 50 in front Ff with respect to a spray mechanism 53 that sprays a liquid chemical outwards from the vehicle 50, and capturing the spray state from the spray mechanism 53; and a monitor unit 3 that displays the video data obtained from the camera unit 2 on at least a part of the monitor screen Vm.

[0012] In this case, according to a preferred embodiment of the invention, the spray state imaging camera 2a can be installed at the rear end 54yr of the roof portion 54y of the cabin portion 54 of the vehicle 50. In this case, it is desirable that the outside of the camera body 11 of the spray state imaging camera 2a be covered by a sealed cover portion 12 having a light-transmitting window 12w. The camera body 11 can also be supported by an angle adjustment mechanism 13 that can adjust the shooting angle Qv in at least the vertical direction. On the other hand, the camera unit 2 can be provided with a rear camera 2b that photographs the rear of the vehicle 50. The rear camera 2b can be attached using a part of the fan guard 55g of the blower mechanism 55 located behind the spray mechanism 53, and this rear camera 2b can be supported by an angle adjustment mechanism 15 that can adjust the shooting angle Qz in at least the vertical direction. Furthermore, the camera unit 2 can be provided with side cameras 2p and 2q that photograph the rear Fr by installing them on the left and right side panels 56p and 56q of the cabin portion 54 of the vehicle 50, respectively. On the other hand, the monitor unit 3 can divide one or more video data obtained from the camera unit 2 into multiple areas Aa, Ab, Ap, Aq on a single monitor screen Vm and display them. The monitor unit 3 can also divide one or more video data obtained from the camera unit 2 into two or more corresponding monitors 3a, 3b, ..., 3n ... and display them. [Effects of the Invention]

[0013] The monitoring system 1 for the speed sprayer M according to the present invention, having such a configuration, produces the following remarkable effects.

[0014] (1) The system includes a camera unit 2 having a spray state capturing camera 2a installed at a predetermined position on the vehicle 50 in front Ff, which sprays a chemical solution outwards from the vehicle 50, and a monitor unit 3 which displays the video data obtained from the camera unit 2 on at least a portion of the monitor screen Vm. As a result, the specific conditions of the speed sprayer M, i.e., the actual spraying conditions, can be easily and accurately confirmed.

[0015] (2) Basically, since there are no optical mirrors whatsoever, it is possible to adequately confirm the necessary field of view. In particular, there is no need to turn towards each of the installed mirrors to check the view, and it is sufficient to check one or a predetermined number of monitor screens Vm installed in the appropriate position in the driver's seat 51, which is convenient and also ensures a higher level of safety, as it allows the operator who is also operating the vehicle to concentrate on driving.

[0016] (3) In a preferred embodiment, if the spray state camera 2a is installed at the rear end 54yr of the roof portion 54y of the cabin portion 54 of the vehicle 50, the entire spray state can be easily and accurately confirmed.

[0017] (4) In a preferred embodiment, if the spraying state camera 2a is covered with a sealed cover portion 12 having a light-transmitting window 12w on the outside of the camera body 11, collisions with fruit tree branches and the like can be avoided and the spraying state camera 2a can be protected.

[0018] (5) In a preferred embodiment, if the camera body 11 is supported by an angle adjustment mechanism 13 that can adjust the shooting angle Qv in at least the vertical direction, the operator can set the desired camera angle, and thus accurately grasp the required shooting range.

[0019] (6) In a preferred embodiment, if a rear camera 2b for photographing the rear of the vehicle 50 is provided in the camera unit 2, it is possible to easily and accurately check the rear of the traveling road or the like and to check for reverse.

[0020] (7) In a preferred embodiment, if the rear camera 2b is attached using a part of the fan guard 55g in the blower mechanism 55 arranged behind the spraying mechanism 53, an optimal arrangement setting can be made using the area of the fan guard.

[0021] (8) In a preferred embodiment, if the rear camera 2b is supported by an angle adjustment mechanism 15 capable of adjusting at least the photographing angle Qz in the vertical direction, the necessary camera angle desired by the operator can be set, so that the necessary photographing range can be accurately grasped.

[0022] (9) In a preferred embodiment, if side cameras 2p and 2q for photographing the rear Fr are provided in the camera unit 2 by being respectively installed on the left and right side panels 56p and 56q of the cab unit 54 in the vehicle 50, operations such as storing (folding) mirrors can be eliminated, collisions with branches of fruit trees and the like can be avoided, and unnecessary damage to fruit trees and the like can be prevented.

[0023] (10) In a preferred embodiment, if one or more pieces of video data obtained from the camera unit 2 are divided and displayed in a plurality of areas Aa, Ab, Ap, Aq of one monitor screen Vm in the monitor unit 3, the overall situation can be checked intensively and easily on one monitor screen Vm.

[0024] (11) In a preferred embodiment, if one or more pieces of video data obtained from the camera unit 2 are divided and displayed on two or more corresponding monitors 3a, 3b,..., 3n,..., an easy-to-see monitor position and size can be arbitrarily selected, and the photographing position and the like can be grasped easily and quickly.

[0026] Next, preferred embodiments of the present invention will be described in detail with reference to the drawings.

[0027] First, in order to facilitate understanding of the monitoring system 1 according to this embodiment, the schematic configuration of the speed sprayer M will be described with reference to Figure 1. Figure 1 shows the overall external configuration of the speed sprayer M. The speed sprayer M has a chassis with a pair of front wheels 61... on the front side and a pair of rear wheels 62... on the rear side. The front wheels 61... and rear wheels 62... are four-wheel driven by an engine mounted on the chassis. On the chassis, a body 63 is mounted, with the front part of the body 63 forming a cabin section 54 and the rear part forming a chemical tank 64 and an engine room 65. Side panels 56p and 56q are installed on the left and right sides of the cabin section 54, and one of the side panels 56p is fitted with an openable door section 66.

[0028] Furthermore, behind the engine compartment 65, there is a spray mechanism 53 that sprays chemical solution outwards using numerous spray nozzles, and behind the spray mechanism 53, there is a blower mechanism 55 that has a blower fan. In addition, in the Speed ​​Sprayer M, 67 is the front windshield, 68p and 68q are the headlights, and 69 is the hose reel for winding up the manual spraying hose. This constitutes the entire vehicle 50 of the Speed ​​Sprayer M.

[0029] Next, the configuration of the monitoring system 1 according to this embodiment, which constitutes the main part of the present invention, will be described with reference to Figures 1-11.

[0030] The basic configuration of the monitoring system 1 includes a camera unit 2 and a monitor unit 3. As shown in the dotted circle A in Figure 1, the camera unit 2 is equipped with a spray state imaging camera 2a that is installed at a predetermined position on the vehicle 50 in front of the spray mechanism 53 Ff and captures the spray state from the spray mechanism 53.

[0031] The basic configuration of the camera unit 2 is shown in Figures 2-4. The spray state imaging camera 2a provided in the camera unit 2 is positioned at the rear end 54yr of the roof portion 54y of the cabin portion 54 of the vehicle 50, as shown in Figures 1-3. By positioning the spray state imaging camera 2a at the rear end 54yr of the roof portion 54y of the cabin portion 54 in this way, the entire spray state can be easily and accurately confirmed.

[0032] In this case, when configuring the spray state imaging camera 2a, as shown in Figure 4, a single mounting plate 21 is provided, and a camera unit 22 is fixed to the lower surface 21d at the rear of this mounting plate 21. This camera unit 22 is formed as a rectangular parallelepiped and has a sealed cover portion 12 with a light-transmitting window 12w on its rear surface. The camera body 11, which is completely covered by this cover portion 12, is then placed in the internal space of the cover portion 12.

[0033] In this way, by covering the outside of the camera body 11 of the spraying state camera 2a with a sealed cover part 12 having a light-transmitting window 12w, collisions with fruit tree branches and the like can be avoided, and the spraying state camera 2a can be protected.

[0034] Furthermore, as shown in Figure 4, the front end of the camera body 11 is supported by an angle adjustment mechanism 13 that can adjust the shooting angle Qv at least in the vertical direction. In this case, the angle adjustment mechanism 13 is composed of a rotatable support part 23 that can be tightened or loosened with bolts and nuts. By loosening the rotatable support part 23, the camera body 11 can be rotated to set the shooting angle Qv in the vertical direction to a predetermined angle, and by tightening the rotatable support part 23, the camera body 11 can be fixed in place.

[0035] Thus, by supporting the camera body 11 with an angle adjustment mechanism 13 that can adjust the shooting angle Qv at least in the vertical direction, the operator can set the desired camera angle, and thus accurately grasp the required shooting range.

[0036] The mounting plate 21, which includes the camera unit 22, is attached to the upper surface of the vehicle 50 at the left-right center position of the rear end 54yr of the roof portion 54y of the cabin portion 54 by bolts and nuts 24, etc., as shown in Figure 1. This allows the spray state imaging camera 2a to capture the entire spray state from the spray mechanism 53.

[0037] On the other hand, the video data output from the spray state imaging camera 2a is transmitted to the in-vehicle controller 71, as shown in Figure 6, and displayed on the monitor unit 3 connected to the in-vehicle controller 71. Figure 5 shows an example of the monitor screen Vm in the monitor unit 3. The example monitor screen Vm is set up as a four-part screen, and the video data from the spray state imaging camera 2a is displayed in the upper area Aa in the central part, which is part of the monitor screen Vm.

[0038] In Figure 5, 37a is a zoom button, and by turning this zoom button 37a ON, the screen of area Aa can be enlarged to fill the entire screen.

[0039] Thus, by equipping the vehicle with a spray condition camera 2a, the operator (driver) can easily and accurately understand the surrounding conditions of the vehicle 50, particularly the specific conditions of the speed sprayer M, i.e., the spray condition. As a result, it is no longer necessary to check within a narrow or limited field of view, or for the operator to turn around to check, as was the case in the past, thus ensuring sufficient safety.

[0040] On the other hand, the speed sprayer M according to this embodiment includes, as cameras 2, a spray state imaging camera 2a, a rear camera 2b shown in dotted circle B in Figure 1, and left and right side cameras 2c and 2d shown in dotted circles C and D.

[0041] Details of the rear camera 2b are shown in Figures 7 and 8. As shown in Figure 7, this rear camera 2b has the function of photographing the area behind the vehicle 50 and is mounted using a part of the fan guard 55g of the blower mechanism 55 located behind the spray mechanism 53.

[0042] The rear camera 2b is constructed using the rear camera unit 25 shown in Figure 8. This rear camera unit 25 includes a camera body 26 and a mounting support part 28 that supports a supported part 26s provided at the front end of the camera body 26 via a rotating support part 27 using bolts and nuts. As a result, the mounting support part 28 can be fixed by sandwiching two adjacent guard rings 55gn and 55gm located at the front and rear of the fan guard 55g with a fixing plate 28s and securing them with bolts and nuts 28t, etc., as shown in Figure 7.

[0043] In this way, by providing a rear camera 2b that photographs the area behind the vehicle 50, it becomes easy and accurate to check the area behind the vehicle, such as the road, and to check when reversing. In particular, by using a part of the fan guard 55g of the blower mechanism 55 located behind the spray mechanism 53, the optimal placement can be set using the area of ​​the fan guard.

[0044] Furthermore, the mounting support portion 28, which rotatably supports the supported portion 26s, also constitutes (and serves as) an angle adjustment mechanism 15 that can adjust the shooting angle Qz in at least the vertical direction for the rear camera 2b, i.e., the camera body 26. In this case, the rotatable support portion 27 provided at the rear end of the mounting support portion 28 is configured to be tightened and loosened by bolts and nuts, etc. By loosening the rotatable support portion 27, the camera body 26 can be rotated and displaced to set the shooting angle Qv in the vertical direction to a predetermined angle, and by tightening the rotatable support portion 27, the camera body 26 can be fixed in place.

[0045] Thus, by supporting the rear camera 2b with an angle adjustment mechanism 15 that can adjust the shooting angle Qz at least in the vertical direction, the operator can set the desired camera angle, and thus accurately grasp the required shooting range.

[0046] Furthermore, as shown in Figure 1, the side cameras 2p and 2q can be installed on the left and right side panels 56p and 56q of the cabin section 54 of the vehicle 50, respectively, to capture images of the rear Fr. In this case, since the right side panel 56p is equipped with an openable door section 66, the right side camera 2p is mounted on the outer side of this door section 66.

[0047] Figures 9-11 show the configuration of one (right) side camera 2p. As shown in Figure 10, the side camera 2p has a rectangular parallelepiped housing 29 without a rear or top surface. A mounting portion 31 is installed inside this housing 29, and the camera body 34 is supported by this mounting portion 31.

[0048] The support portion at the front of the camera body 34 is supported by a pivot support portion 32 such as a bolt and nut via the vertical portion 31v of the mounting portion 31. As a result, the rear of the camera body 34 is supported by an angle adjustment mechanism 33 that can adjust the shooting angle Qx in at least the vertical direction, as shown in Figure 11. Since the angle adjustment mechanism 33 is composed of a pivot support portion 32 that can be tightened and loosened, the camera body 34 can be rotated by loosening the pivot support portion 32 to set the shooting angle Qx in the vertical direction to a predetermined angle, and the camera body 34 can be fixed by tightening the pivot support portion 32.

[0049] Furthermore, the horizontal portion 31h of the mounting portion 31 is fixed to the bottom surface 29h of the housing 29 by a fixing portion 35 such as a bolt and nut. In this case, an elongated hole is formed in the horizontal portion 31h, so that the camera body 34 can be displaced left or right and its position adjusted by loosening the fixing portion 35, and the camera body 34 can be fixed by tightening the fixing portion 35.

[0050] Furthermore, the housing 29 is sealed by a cover portion 36 having a rear portion 36r and an upper portion 36u. A light-transmitting window 36w is provided in the rear portion 36r of the cover portion 36. As a result, the camera body 34 can capture the view of the rear Fr of the vehicle 50 through the light-transmitting window 36w.

[0051] While the side camera 2p installed on one (right) side panel 56p (door section 66) has been described, the side camera 2q installed on the other (left) side panel 56q can be configured in a similar manner, except that it is in a symmetrical position.

[0052] In this way, by installing side cameras 2p and 2q on the left and right side panels 56p and 56q of the cabin section 54 of the vehicle 50, respectively, it is possible to eliminate operations such as retracting (folding) mirrors, and to avoid collisions with fruit tree branches, etc., and prevent unnecessary damage to fruit trees, etc.

[0053] The rear camera 2b and side cameras 2p and 2q are then connected to the in-vehicle controller 71, as shown in Figure 6. As a result, the video data output from each camera 2b, 2p, and 2q is displayed on the monitor unit 3 connected via the in-vehicle controller 71.

[0054] In this case, as shown in Figure 5, the data is displayed in the corresponding areas Ab… of the monitor screen Vm. Specifically, the video data obtained from the rear camera 2b is displayed in the lower area Ab in the central part of the monitor screen Vm, the video data obtained from the side camera 2p is displayed in the right area Ap which is part of the monitor screen Vm, and the video data obtained from the side camera 2q is displayed in the left area Aq which is part of the monitor screen Vm.

[0055] In Figure 5, 37b, 37p, and 37q are zoom buttons, similar to zoom button 37a. When turned ON, the screens of areas Ab, Ap, and Aq can be enlarged to fill the entire screen.

[0056] In this way, by displaying one or more video data obtained from the camera unit 2 on the monitor unit 3, divided into multiple areas Aa, Ab, Ap, and Aq on a single monitor screen Vm, there is an advantage in that the overall situation can be centrally and easily checked on a single monitor screen Vm.

[0057] On the other hand, Figures 12 and 13 show examples of modifications to the monitor unit 3 in the monitoring system 1. The modification shown in Figure 12 uses three monitors 3a, 3p, and 3q. The upper area Aa of the central monitor 3a displays video data output from the spray state imaging camera 2a, and the lower area Ad displays video data output from the rear camera 2b. In addition, the left and right monitors 3p and 3q display video data output from the side cameras 2p and 2q, respectively.

[0058] Furthermore, another example of modification shown in Figure 13 uses two monitors, 3m and 3n. The left monitor 3n displays a split screen, with the left area Aq displaying video data output from the side camera 2q and the right area Aa displaying video data output from the spray state camera 2a. Additionally, the right monitor 3m also displays a split screen, with the left area Ab displaying video data output from the rear camera 2b and the right area Ap displaying video data output from the side camera 2p.

[0059] As shown in each example of modification, by displaying one or more video data obtained from the camera unit 2 on the monitor unit 3, divided among two or more corresponding monitors 3a, 3p, ..., 3n ..., it is possible to arbitrarily select a monitor position and size that is easy to view, and it is also possible to easily and quickly grasp the shooting position, etc.

[0060] Therefore, according to the monitoring system 1 for the speed sprayer M according to this embodiment, the basic configuration includes a camera unit 2 having a spray state capturing camera 2a that is installed at a predetermined position on the vehicle 50 in front Ff and captures the spray state from the spray mechanism 53 that sprays a liquid chemical solution outwards from the vehicle 50, and a monitor unit 3 that displays the video data obtained from the camera unit 2 on at least a part of the monitor screen Vm. As a result, the specific conditions of the speed sprayer M, i.e., the actual spray state, can be easily and sufficiently and accurately confirmed.

[0061] Furthermore, since there are essentially no optical mirrors, it is possible to adequately check the necessary field of view. In particular, there is no need to turn towards each installed mirror to check the view; it is sufficient to check one or a predetermined number of monitor screens Vm installed in the appropriate position in the driver's seat 51. This is highly convenient and ensures greater safety, as it allows the operator, who is also operating the vehicle, to concentrate on driving.

[0062] Although preferred embodiments have been described in detail above, the present invention is not limited to these embodiments, and the details of the configuration, shape, materials, quantity, numerical values, etc. can be arbitrarily changed, added, or deleted without departing from the spirit of the present invention.

[0063] For example, the spray condition imaging camera 2a is optimally positioned at the rear end 54yr of the roof portion 54y of the cabin portion 54 of the vehicle 50, but is not necessarily limited to this position or mounting method. Also, although the camera unit 2 is shown to include a rear camera 2b and side cameras 2p and 2q, these are not necessarily essential components, and one or more other cameras may be included in other positions as needed. Furthermore, as the monitor unit 3, examples were given of displaying one or more video data obtained from the camera unit 2 divided into multiple areas Aa, Ab, Ap, Aq on a single monitor screen Vm, and displaying one or more video data obtained from the camera unit 2 divided into two or more corresponding monitors 3a, 3b…, 3n…, but the number of monitors and display method constituting the monitor unit 3 are not limited to these examples.
