Below, a demonstration kit (hereinafter referred to as a demo kit) for a safety support device according to one embodiment of the present invention will be described with reference to Figures 1 to 9.

The demo kit 1 is used for a refuse collection vehicle 2. The refuse collection vehicle 2 in this case has a general configuration, and is provided with a pusher 5 and a rotating plate 6 as a working device 3 inside the rear of the refuse collection vehicle 2. In addition, a refuse inlet 7 for a worker 4 (person) to put in refuse is provided further rearward of the working device 3. The demo kit 1 is provided independently of the refuse collection vehicle 2 and is temporarily applied to the refuse collection vehicle 2. The demo kit 1 is used for a refuse collection vehicle 2 that is not equipped with a safety support device that ensures the safety of the worker 4, for example, by a person in charge of a business that handles safety support devices (such as a special vehicle manufacturer) to carry out a demonstration of the safety support device. This demonstration is, for example, a demonstration of a safety support device that is installed on the refuse collection vehicle 2 to ensure the safety of people such as the worker 4 around the working device 3. Additionally, for example, demonstrations will be conducted for those in charge of those considering purchasing the garbage collection vehicle 2 (local governments and businesses that collect garbage) and collection workers.

As shown in FIG. 2, the demo kit 1 has an attache case-like appearance and is equipped with a rectangular parallelepiped housing 10. As shown in FIGS. 2 to 6, the housing 10 is made of, for example, hard plastic, and has a top 13, a bottom 14 facing downward thereto, side portions 15 and 16 on one side, and side portions 17 and 18 on the other side. Note that the directional indications "top," "bottom," and "side" correspond to the directions in the state shown in FIGS. 1 to 6. However, the handling direction of the demo kit 1 is not limited to this direction. A handle 20 is arranged on the top 13 of the housing 10 to enable the housing 10 to be transported.

The housing 10 is separable into two halves by arranging a hinge portion 21 on the bottom 14 of the housing 10. The housing 10 comprises a housing body 11 and a lid 12. The housing body 11 and the lid 12 can be opened and closed via the hinge portion 21. The housing body 11 is open on one side (the lid 12 side), and the lid 12 is open on the other side (the housing body 11). The components of the demo kit 1 can be stored in the open space. This allows all the components of the demo kit 1 to be gathered together, making it easier to transport. The demonstration is performed with the lid 12 open from the housing body 11 to expose the display 29 and keyboard 30.

As shown in FIG. 6, a frame 11a is formed on the outer periphery of the housing body 11, and a body mounting member 34 on which a control device 28 (described later) and the like are arranged is attached inside the frame 11a on the lid 12 side. This body mounting member 34 is plate-shaped. The body mounting member 34 is supported by a stepped portion 11b formed on the inside of the frame 11a and having a similar shape to the frame 11a. The body mounting member 34 has a fixed plate 34a and a door 34b attached to the fixed plate 34a via a butterfly plate 34c, and the fixed plate 34a is fixed to the stepped portion 11b.

As shown in FIG. 4, a frame 12a is formed on the outer periphery of the lid 12, and a lid mounting member 37 on which a display 29 (described later) is arranged is attached inside the frame 12a, on the side of the housing body 11. The lid mounting member 37 is plate-shaped. The lid mounting member 37 is fixed by a stepped portion 12b, which is formed inside the frame 12a and has a similar shape to the frame 12a.

1, a locking mechanism 22 is disposed between the housing body 11 and the lid 12 (both the left and right ends of the top 13) and in the middle of the sides 17, 18 in the vertical direction. By connecting the engaging portion 22A and the engaged portion 22B of the locking mechanism 22, the frame portions 11a, 12a of the housing body 11 and the lid 12 come into contact with each other to form the housing 10. The housing 10 is transported in this state. By releasing the engaging portion 22A and the engaged portion 22B of the locking mechanism 22, the frame portions 11a, 12a of the housing body 11 and the lid 12 can be opened and closed around the hinge portion 21, and the housing body 11 and the lid 12 can be opened and closed. The frame portions 11a and 12a on the hinge portion 21 side are equipped with stoppers (not shown), and the lid 12 is configured to swing open by approximately 95 degrees relative to the housing body 11 and stop in that position (dashed line in FIG. 3). In other words, when the side portion 15 of the housing body 11 is placed on the ground or a desk and the lid 12 is opened around the hinge portion 21, the stoppers act to hold the lid 12 in a generally upright position. The demonstration is performed in this state.

As components of the demo kit 1, several parts stored in the housing 10 will be described. These parts are a camera 23, an arm (corresponding to a camera installation means) 24, a cable 25, a battery (corresponding to a power source) 26, an AC adapter (corresponding to a power source) 27, a control device 28, a display 29, a lamp 38, and a keyboard 30.

In this embodiment, the camera 23 is temporarily installed at the rear of the refuse collection vehicle 2 above the refuse inlet 7 in order to capture an image of the work area where the worker 4 loads refuse onto the work device 3. The camera 23 has a lens and an image sensor that captures an image of the work area through the lens. The camera 23 in this embodiment captures video and has a wide-angle lens that can capture a sufficient range (wide range) when capturing an image of the work area. The image captured by the camera 23 is, for example, an image of the danger area D captured from above and facing backward of the refuse collection vehicle 2. This danger area D is, for example, an area where there is a high possibility of an accident in which the worker 4 gets caught in the work device 3 (loading device 5, rotating plate 6, etc.) while in operation.

This danger area D is displayed on the image of the work area displayed on the display 29. Incidentally, the demo kit 1 of this embodiment is for demonstration purposes, and it is sufficient for the person receiving the demonstration to confirm how the safety support device can ensure the safety of the person. Therefore, unlike a safety support device fixedly installed on a garbage collection vehicle, it does not have the function of forcibly stopping the working device 3 in operation even if the image of a person overlaps the danger area D. However, it is possible to modify the demo kit 1 of this embodiment in an advanced manner, connect the control wiring from the demo kit 1 to the input terminal of the control circuit mounted on the garbage collection vehicle 2, i.e., the control circuit (PLC), and connect it to the emergency stop wiring to forcibly stop the working device 3 that is actually in operation during the demonstration.

The imaging element is, for example, a CCD image sensor, a CMOS image sensor, etc., and outputs a video signal of the captured image (in this embodiment, a moving image). The camera 23 is also connected to the control device 28 via a cable 25, and outputs a video signal to the control device 28.

The arm 24 is a part for installing the camera 23 on the refuse collection vehicle 2. The arm 24 has an attachment portion 31 for attaching it to the refuse collection vehicle 2. The portion of the rear body of the refuse collection vehicle 2 above the refuse inlet 7 is made of a magnetic material such as steel. For this reason, the attachment portion 31 of the arm 24 is configured with a permanent magnet, and the arm 24 is configured so that it can be attached and detached to the rear body by the permanent magnet. The camera 23 is installed on the refuse collection vehicle 2 temporarily, not permanently, and the demonstration is performed while the refuse collection vehicle 2 is stationary, so there is no problem with the permanent magnet used for attachment and detachment.

The arm 24 is composed of a plurality of arm bodies 32, and the plurality of arm bodies 32 are connected to each other by a plurality of joint members 33 that can rotate around an axis that is approximately parallel to the horizontal direction when attached to the garbage collection vehicle 2 as shown in FIG. 1, and each arm body 32 is foldable by the plurality of joint members 33. Since the arm 24 can be made compact by folding, it is easy to store it in the housing 10. In addition, in this embodiment, the camera 23 and the arm 24 are configured as separate members, and are each removed from the housing 10 and assembled when performing a demonstration. In addition, the arm 24 in this embodiment has two joints 33 on the two arm bodies 32, but it may have three or more. In addition, the joint members 33 may be joints that rotate around the axis around which the arm body 32 extends, or ball joints. The arm 24 may be equipped with a mechanism that allows the position of the camera 23 to slide up, down, front, back, left and right relative to the mounting member 31, and the arm body 32 may be configured to be extendable.

The cable 25 is long and flexible, and is a member that electrically connects the control device 28 and the camera 23. This connection transmits driving power and video signals between the control device 28 and the camera 23. The camera 23, arm 24, and cable 25 can be stored in the housing 10, and when storing them in the housing 10, they are stored in, for example, the housing body 11. For example, the body attachment member 34 is configured to be detachable from the housing body 11, so that the camera 23, arm 24, and cable 25 can be stored in the space S inside the housing body 11 that appears when the body attachment member 34 is opened.

The battery 26, the AC adapter 27, and the control device 28 are arranged on the back side of the main body attachment member 34. The battery 26 is a power source that is completed within the housing 10. The AC adapter 27 is a power source used when supplying power from outside the housing 10, and is also used when charging the battery 26. The back side of the main body attachment member 34 is the surface that faces the inner surface of the housing main body 11. For example, in FIG. 5, the battery 26, the AC adapter 27, and the control device 28 are fixed offset to one side of the housing main body 11 (the left side of FIG. 5), forming a space S on the other side. This space S can be exposed by opening the door 34b, and the camera 23, the arm, and the cable 25 can be stored therein. However, the positions of the battery 26, the AC adapter 27, and the control device 28 relative to the main body attachment member 34 are not limited to this position, and can be determined arbitrarily as long as they can be stored therein. The control device 28 operates by obtaining power from the battery 26 or the AC adapter 27. The charger (not shown) obtains power from the AC adapter 27 and charges the battery 26.

A keyboard 30 for operating the control device 28 is disposed on the surface of the main body mounting member 34, that is, on the surface in a state in which the housing main body 11 and the cover body 12 are rotated relatively around the hinge portion 21. In addition, a plurality of lamps 38 as display devices are disposed on the surface of the main body mounting member 34 at a predetermined interval from the keyboard 30. These lamps 38 are composed of an operation lamp 38a that indicates that the demo kit 1 (control device 28) is operating (operating normally), a detection lamp 38b that indicates that an image of a person has been captured in the captured image H, specifically, that an image corresponding to a person has entered the captured image H, and a stop lamp 38c that indicates that a person has been captured in the dangerous area D in the captured image H, specifically, that an image corresponding to a person has entered the detection area D, and corresponds to a case in which the working device 3 is forcibly stopped in an actual safety support device. In addition, the detection lamp 38b can also indicate that a person's image has entered the dangerous area D (see FIG. 8) side of the line A. In this case, the presence or absence can be displayed by operating the keyboard 30, and it may be possible to switch between display and non-display (or enable and disable). Also, the lamps 38 are equipped with an operating lamp 38a, a detection lamp 38b, and a stop lamp 38c, but other notification means may also be used.

A display 29 is disposed in the center of the lid mounting member 37 of the lid body 12 as a display device electrically connected to the control device 28. In this embodiment, the display 29 is a liquid crystal display, and displays an image of the work area captured by the camera 23. The display 29 also displays information to be notified to ensure safety, such as a line indicating the danger area D. This information is displayed superimposed on the image of the work area.

On the display 29, an installation position guide L is displayed as a guide display that guides the user to the appropriate installation state of the camera 23 on the garbage collection vehicle 2 by image display. The installation position guide L is displayed on the image of the display 29 (see FIG. 8). Specifically, a line is drawn on the captured image (screen) H of the display 29 sent from the camera 23, in this case a "red straight line", and is drawn in the left-right direction below the captured image H. In this way, when the installation position guide L is displayed as a line, it is preferable to use a line with a color that is easily distinguishable from the captured image displayed on the display 29. The display position of the installation position guide L on the display 29 can be changed by operating the keyboard 30. In addition, the installation position guide L can be switched between display and non-display by operating the keyboard 30, and for example, after the installation of the camera 23 is completed, it can be hidden by operating the keyboard 30. In addition, the keyboard 30 can be used to switch between display and non-display of the dangerous area D, and to change the boundary position of the dangerous area D in the up-down, left-right, and right directions of the display.

The control device 28 has the following functions: When it is determined that the worker 4 included in the captured image H from the camera 23 has entered a danger area D set on the image of the display 29, the control device 28 causes a lamp 38 acting as a display device to issue an alarm to notify that the worker 4 has entered the danger area D. Specifically, the control device 28 alerts the operator 4A performing the demonstration (such as a special vehicle manufacturer representative) and those around the demo kit 1 by turning on or blinking the stop lamp 38c.

As shown in FIG. 7, the circuit diagram of the electronic components of the demo kit 1 described above is configured as follows. The control device 28 and display devices (display 29, lamp 38) are connected to a power source (battery 26 or AC adapter 27), and the display 29 is placed on the output side of the control device 28 via HDMI (registered trademark; High-Definition Multimedia Interface). The keyboard 30 is connected to the input side of the control device 28 via USB (Universal Serial Bus). The camera 23 is connected to a connector 39 that can be detached to the outside of the housing 10, and the connector 39 is connected to the input side of the control device 28 via NTSC (National Television System Committee), and the connector 39 is connected to the lamp 38.

The usage method of the demo kit 1 will be explained. When the engaging portion 22A and the engaged portion 22B of the locking mechanism portion 22 provided on the housing 10 are removed, the housing body 11 and the cover body 12 are opened around the hinge portion 21. Then, the operator 4A removes the camera 23, the arm 24, and the cable 25 from the housing body 11 to prepare them, and attaches the camera 23 to the arm 24. Then, the camera 23 is attached to the cable 25 and the cable 25 is attached to the connector 39. Then, the arm 24 is placed above the garbage inlet 7. At this time, the attachment portion 31 is attached near the center of the garbage collection vehicle 2 in the vehicle width direction with a permanent magnet. Also, in the arm 24, the joint member 33 is bent as necessary to point the camera 23 diagonally downward. Also, if necessary, the cable 25 is held against the outer wall of the garbage collection vehicle 2 by a clamp (with a permanent magnet) previously provided on the cable 25.

In addition, within the extension range of the cable 25, the housing 10 can be moved around the garbage collection vehicle 2 to a convenient position for demonstration.

After these operations, the demo kit 1 is operated. At this time, the operation lamp 38a can be used to confirm whether the demo kit 1 is operating or not. As shown in FIG. 8, the camera 23 is adapted to capture an image of the work area in which the worker 4 works with respect to the work device 3. Since the control device 28 and the camera 23 are electrically connected by a cable 25, the operator 4A adjusts the shape of the arm 24 and the camera angle so that the camera 23 reliably captures the work area. At this time, the shape of the arm 24 and the camera angle are adjusted so that in the captured image H, the vicinity of the widthwise end of the lower edge 7a of the trash inlet 7 coincides with the left and right ends of the installation position guide L attached to the display 29.

If the camera 23 reliably captures the work area, the worker 4 throws the garbage through the garbage inlet 7. Alternatively, the worker 4 pretends to throw the garbage through the garbage inlet 7. In this case, the image of the worker 4 is reflected in the captured image H. The image of the worker 4 is displayed in the captured image H surrounded by a rectangular frame. The reflection is detected by the rectangular frame. The control device 28 determines that the worker 4 has been reflected, and outputs a lighting signal (or a blinking signal) to the detection lamp 38b to turn it on (or blink). If the worker 4 has entered the danger area D as shown in FIG. 9, the control device 28 determines that the worker 4 has entered the danger area D, and outputs a lighting signal (or a blinking signal) to the stop lamp 38c to turn it on (or blink), and turns off the lighting (or blinking) of the detection lamp 38b. This lets operator 4A know that worker 4 has entered dangerous area D. This intrusion into dangerous area D is also detected by the rectangular frame corresponding to worker 4. It can be said that detection in progress lamp 38b and stop lamp 38c function as a notification section (notification means) that can notify operator 4A based on the image captured by camera 23. It is also possible to change the color of the rectangular frame corresponding to worker 4 displayed in captured image H depending on whether the worker is outside dangerous area D or has intruded.

By changing the danger area D during the demonstration, for example by changing the detection area D to a location far from the garbage inlet 7 (upper part in Figure 8), the loading device 5 will be more likely to stop when the worker 4 puts garbage into the garbage inlet 7 or pretends to put garbage into it. This allows the user to experience the degree of sensitivity of the safety support device.

Therefore, according to the demo kit 1 of this embodiment, even if the garbage collection vehicle 2 is not equipped with a safety support device, the function of the safety support device can be experienced in response to the request of the operator 4A. In addition, since the demo kit 1 can be operated even when the key to the garbage collection vehicle 2 is removed, there is no need to actually operate the working device 3 (pushing device 5 and rotating plate 6) linked to the key, which prevents entanglement accidents during the demonstration and ensures safety.

The present invention is not limited to the above embodiment. In the above embodiment, the display device includes the lamp 38, but it may include only the display 29 without the lamp 38. In this case, the display 29 can notify the operator 4 that he has entered the danger area D. This notification can be achieved by displaying an icon on the screen when the lamps 38a to 38c are in a state where they should be lit. The notification may be made by an auditory sense such as a voice or alarm instead of or in addition to the lamp. When an audio display is used, it is necessary to provide a speaker on the display device.

In the above embodiment, the camera 23 and the arm 24 are separate, but the camera 23 and the arm 24 can also be integrated (i.e., a camera with an arm). Also, in the above embodiment, the arm 24 is configured to be detachably attached to the rear body of the garbage collection vehicle 2 by a permanent magnet, but the configuration for making it detachable from the rear body is not limited to this, and various configurations that can be temporarily attached to the garbage collection vehicle 2, such as an electromagnet (excited by power from the battery 26 or AC adapter 27 and equipped with a switch in the wiring to switch between supplying and cutting off power), a suction cup, adhesive, hook, etc., can be used.

In the above embodiment, the display 29 is configured to display the installation position guide L, but the installation position guide L is not necessarily required.

In addition, in the above embodiment, the guide display is the installation position guide L as a horizontal line, but there may be multiple types of installation position guide L, for example, it may be an inclined line L1 (Figure 8) for aligning with the left and right side edges 7b of the garbage inlet 7. The installation position guide L as a guide display is not limited to being linear (straight line) as in the above embodiment, but can also be a frame-shaped, lattice-shaped, circular, or other dot-shaped M. If it is a frame-shaped or lattice-shaped guide, it can be aligned with the rectangular garbage inlet 7, and if it is a dot-shaped guide M, it can be aligned with the corners of the garbage inlet 7. The installation position guide L can also be displayed at the top or center of the captured image.

In the above embodiment, the camera 23, the arm 24, and the cable 25 are freely storable in the housing body 11 of the housing 10, but the storage positions within the housing 10 are not particularly limited. Also, the housing 10 is limited to a rectangular parallelepiped shape, but it can be formed into various shapes that are easy for the operator 4A to use. Also, in the above embodiment, the housing 10 is made of hard plastic, but it may be bag-shaped and made of a soft material.

In the above embodiment, the camera 23, arm 24, and cable 25 are stored in the housing body 11, for example. However, the camera 23, arm 24, and cable 25 can be carried separately from the housing 10 without being stored in the housing 10.
