Description

[Technical Field]

[0001] The present invention relates to a monitoring device or the like equipped with a camera unit. [Background technology]

[0002] At construction sites in urban areas, there is often not enough space to set up a construction office on-site, so the office is often set up somewhere far from the construction site. In such cases, construction personnel must travel back and forth between the construction office and the construction site multiple times a day to monitor the on-site situation. Furthermore, in urban areas, buildings tend to be taller, resulting in a lot of vertical movement even within construction sites. During construction, the use of passenger and freight elevators is limited, so workers are often forced to move between floors by stairs, which is a significant burden in terms of both time and effort.

[0003] Under these circumstances, there is a movement to promote remote monitoring of construction sites using surveillance cameras in line with the promotion of labor-saving and work style reform. This allows the progress of construction to be grasped in real time and is also effective in terms of safety management. For example, Patent Document 1 discloses a construction site monitoring system that uses a camera unit that ascends and descends along a vertical hoistway by winding and unwinding a wire rope with a winch. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 6-165184 Summary of the Invention [Problem to be solved by the invention]

[0005] Surveillance cameras require a power source to operate. However, if the surveillance camera is battery-powered, the battery must be replaced whenever it runs out of power, which is a hassle. In Patent Document 1, power is supplied to the camera unit via a power cord, but the power cord must be routed in a way that does not interfere with the wire rope used to raise and lower the camera unit, which requires complex consideration. Measures are also needed to prevent the power cord from getting caught on something and to prevent workers from tripping over it.

[0006] The present invention has been made in view of the above problems, and has as its object to provide a surveillance device or the like that is excellent in terms of power supply to a camera unit, etc. [Means for solving the problem]

[0007] The first invention to solve the above problem is ,above This surveillance device comprises a guide rail extending downward, a surveillance camera unit that moves up and down along the guide rail and is equipped with a wireless communication device, a winch unit that moves the camera unit up and down by winding and unwinding a wire attached to the camera unit, and a charging unit that is attached to the guide rail and charges the camera unit when the camera unit reaches a predetermined height along the guide rail, wherein the charging unit is suspended from above by a hanging material and is installed above the camera unit without being fixed in height. No. 2 The invention is a surveillance device comprising a guide rail extending vertically, a surveillance camera unit that moves up and down along the guide rail and is equipped with a wireless communication device, a winch unit that moves the camera unit up and down by winding and unwinding a wire attached to the camera unit, and a charging unit that is provided on the guide rail and charges the camera unit when the camera unit reaches a predetermined height along the guide rail, wherein the charging unit is provided above the camera unit and has a recess at the end of the plane of the charging unit that faces the guide rail, and the wire is passed through the recess. No. 3 The invention is a monitoring device comprising: a guide rail extending vertically; a monitoring camera unit that moves up and down along the guide rail and is equipped with a wireless communication device; a winch unit that moves the camera unit up and down by winding and unwinding a wire attached to the camera unit; and a charging unit that is mounted on the guide rail and charges the camera unit when the camera unit reaches a predetermined height along the guide rail. The winch unit is mounted above the guide rail, and a wire position adjustment mechanism is provided between the winch unit and the guide rail that adjusts the planar position of the wire extending from the winch unit to match the planar position of the guide rail. The wire position adjustment mechanism comprises a gripping portion that grips a single pipe of temporary scaffolding or a single pipe supported on a main body, a first rail extending outward from the gripping portion, a second rail that is arranged in a direction perpendicular to the first rail in a plan view and that is movable along the first rail, and a plurality of pulleys that are movable along the second rail and for hanging the wire. No. 4 The invention is a surveillance device comprising a guide rail extending vertically, a surveillance camera unit that moves up and down along the guide rail and is equipped with a wireless communication device, a winch unit that moves the camera unit up and down by winding and unwinding a wire attached to the camera unit, and a charging unit that is attached to the guide rail and charges the camera unit when the camera unit reaches a predetermined height along the guide rail, wherein the camera unit has a photographing device that is rotatable so as to change the shooting direction in a plane within a predetermined angular range, and an arm member that rotates within a plane around one end and has the photographing device attached to the other end, and when the shooting direction in the plane of the photographing device is changed beyond the predetermined angular range, the arm member is rotated after detecting by a sensor that the shooting direction in the plane of the photographing device is at the end of the predetermined angular range.

[0008] The monitoring device of the present invention realizes the aforementioned labor-saving and work style reforms by remotely monitoring construction sites and other sites. By raising and lowering the camera unit by winding and unwinding a wire, a single camera can monitor at different heights. This eliminates the need to install cameras on each floor of a building, reducing installation labor and eliminating the need to rearrange and remove cameras as construction progresses on each floor. Furthermore, the camera unit is charged by a charging unit at a predetermined height along the guide rail, significantly reducing the effort required for camera unit battery replacement. Furthermore, the camera unit does not require cables such as a power cord, eliminating interference between the cables and wires and eliminating the need for measures to prevent snagging or tripping on the cables. Furthermore, the images captured by the camera unit can be transmitted to a remote construction office or other location via a wireless communication device, eliminating the need for LAN cables.

[0009] No. 1 In this invention, the impact when the camera unit and the charging unit come into contact can be reduced, and damage to the charging unit can be prevented.

[0010] No. 2 In this invention, a wire can be passed through the recess of the charging unit, and the camera unit below the charging unit can be raised and lowered using the wire. After the camera unit with the wire attached is set on the guide rail, the charging unit can be installed.

[0011] No. 3 The wire position adjustment mechanism of the present invention allows the position of the wire unwound from the winch unit to be adjusted to match the guide rail (camera unit), improving the degree of freedom in the installation position of the winch unit. Furthermore, by configuring the wire position adjustment mechanism using the above-mentioned gripping part, rail, and pulley, the wire position adjustment mechanism is simplified and the wire position can be easily adjusted.

[0012] The guide rail is constructed by attaching multiple upper and lower rail members to a single pipe of the temporary scaffolding or a single pipe supported on the main body. This allows guide rails of any height to be easily installed using temporary scaffolding or a structure.

[0013] No. 4 In the invention, by utilizing a sensor to combine the rotation of the camera device with the rotation of the arm member, the camera device can capture images of a wide range, making it possible to monitor a wide range.

[0014] The winch unit is preferably equipped with a wireless communication device for remote control. This allows the camera unit to be raised and lowered remotely. This type of camera unit will contribute to work style reforms and also contribute to business continuity on site, as it can determine the extent of damage to buildings unmanned even if a disaster such as an earthquake or typhoon occurs at night or during business holidays.

[0015] It is desirable that the camera unit issues at least one of an audible and a visual warning when ascending or descending. By sounding an alarm when the camera unit is raised or lowered, it is possible to warn workers and prevent them from coming into contact with the camera unit, and it is also expected to be effective in improving workers' safety awareness. [Effects of the Invention]

[0018] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

[0019] Fig. 1 is a diagram showing a monitoring device 1 according to an embodiment of the present invention. As shown in Fig. 1, the monitoring device 1 is installed on temporary scaffolding 200 arranged along the skeleton 100 of a building, and includes a guide rail 2, a winch unit 3, a camera unit 5, a charging unit 6, a wire position adjustment mechanism 7, etc. The monitoring device 1 monitors a construction site during construction, and one or more monitoring devices 1 can be installed depending on the planar shape and size of the construction site.

[0020] The guide rail 2 is a rail that is arranged in the vertical direction. The guide rail 2 is made up of rail members of a predetermined length connected in multiple vertical stages, and can be made to any height. FIG. 2(a) is a diagram showing the rail member 20. The rail member 20 has a substantially square cross section, with a hole 21 provided in the center and grooves 22 provided on each of the four sides of the cross section. The hole 21 and grooves 22 are provided along the longitudinal direction of the rail member 20.

[0021] When connecting rail members 20, a metal core rod 23 having an outer diameter corresponding to the hole 21 is inserted into the hole 21 of the lower rail member 20 as shown by arrow a. At the middle part in the longitudinal direction of the core rod 23, a ring-shaped protrusion 231 is provided on the outer periphery of the core rod 23 by a rubber band or the like, and the protrusion 231 is engaged with the upper surface of the lower rail member 20 as shown in FIG. 2(b).

[0022] 2(c), the upper rail member 20 is lowered, the upper part of the core rod 23 is inserted into the hole 21 of the rail member 20, and the upper rail member 20 is placed on the lower rail member 20. This positions the upper and lower rail members 20 on a plane. The upper and lower rail members 20 can be fixed by fastening fixing brackets (not shown) to the upper and lower rail members 20 with bolts or the like.

[0023] As shown in Fig. 1, the rail members 20 of each stage are attached to single pipes 201 in the vertical direction of the temporary scaffolding 200 by mounting fixtures 26, and are arranged in the gap between the main structure 100 and the temporary scaffolding 200. However, this is not limited to this, and the rail members 20 can also be attached to single pipes supported by the main structure 100, such as beams or auxiliary steel frames of a building. Note that the single pipes 201 of the temporary scaffolding 200 include not only the single pipes that make up the temporary scaffolding 200, but also other single pipes attached to the temporary scaffolding 200.

[0024] The winch unit 3 is provided on the temporary scaffolding 200 above the guide rail 2. The winch unit 3 winds and unwinds the wire 4 to raise and lower the camera unit 5 along the guide rail 2.

[0025] 3 is a diagram showing the winch unit 3. The winch unit 3 includes a winch 31, a wireless communication device 32, and an operation panel 33. Power is supplied to the winch unit 3 from a distribution panel or the like on the nearest floor via a power cable 34. Two cables 35, one for power supply and one for communication, extend from the winch unit 3 to the charging unit 6.

[0026] The winch 31 raises and lowers the camera unit 5 by winding and unwinding the wire 4. The winch 31 is provided with a drum 311 around which the wire 4 is wound, and is also provided with a mechanism 312 for preventing the wire 4 from being wound around the drum 311 in an irregular manner.

[0027] FIG. 4 is a diagram showing the irregular winding prevention mechanism 312. In this embodiment, irregular winding of the wire 4 is prevented by using a movement mechanism using a ball screw 3122. That is, a positioning unit 3121 that determines the planar position of the wire 4 wound around the drum 311 is provided on the ball screw 3122, and while the wire 4 is being wound, a motor 3123 rotates the ball screw 3122 around its axis, moving the positioning unit 3121 in the axial direction of the ball screw 3122 (corresponding to the left-right direction in FIG. 4). This allows the wire 4 to be wound evenly around the drum 311.

[0028] Although not shown, the winch 31 is also provided with a roller for applying tension to the wire 4 unwound from the drum 311, an encoder for measuring the unwound length of the wire 4, and a winch control unit (not shown) for controlling the winding and unwinding of the wire 4. The winding and unwinding of the wire 4 is also controlled such that when an overload on the wire 4 is detected, the wire 4 is not wound any further, and when an underload on the wire 4 is detected, the wire 4 is not unwound any further.

[0029] The wireless communication device 32 is used to remotely control the winding and unwinding of the wire 4 by the winch 31. In other words, the winch unit 3 is connected to a computer in a construction office or the like via the wireless communication device 32 so that it can communicate with the computer, and the winch 31 can wind and unwind the wire 4 in response to instructions from the computer in the construction office or the like to the winch control unit. This allows the camera unit 5 to be remotely controlled to be raised and lowered.

[0030] The control panel 33 is provided with dials and switches for manual operation, a keyhole for inserting a key to switch between manual operation and remote operation, etc. Manual operation can be performed by inserting the key into the keyhole and turning it to a specified angle. When remote operation is to be performed, the key is removed from the keyhole to prevent manual operation.

[0031] 5 is a diagram showing the camera unit 5 and charging unit 6. The camera unit 5 is used to monitor a construction site, and moves up and down along the guide rail 2 by winding and unwinding the wire 4 with the winch unit 3. The charging unit 6 charges the battery 54 of the camera unit 5. The charging unit 6 is provided above the camera unit 5, at the upper end of the guide rail 2.

[0032] As shown in FIG. 5, the camera unit 5 includes an image capturing device 51, a base 52, an arm member 53, a battery 54, a wireless communication device 55, rollers 56 and 57, a hook 58, an alarm device 59, and the like.

[0033] The image capturing device 51 is a camera that captures images (video) of the construction site and can be rotated within a predetermined angle range on a plane. In addition, the image capturing device 51 can also be rotated (tilted) within a vertical plane.

[0034] The base 52 is a support section that supports the imaging device 51, arm member 53, battery 54, wireless communication device 55, alarm device 59, etc., and moves up and down along the guide rails 2. Reference numeral 521 in Fig. 5 denotes a heat exhaust mechanism provided on the base 52, and is equipped with a fan and a dust filter on the underside.

[0035] One end of an arm member 53 is attached to the base 52. The other end of the arm member 53 is provided with the imaging device 51. The arm member 53 is rotatable in a plane around the one end.

[0036] Battery 54 is provided on top of camera unit 5 and supplies power to imaging device 51, wireless communication device 55, alarm device 59, etc. Battery 54 is charged by charging unit 6. As such, camera unit 5 is battery-powered, so no power cable or the like is required.

[0037] The wireless communication device 55 is communicably connected to a computer at a construction office or the like, and transmits the images captured by the imaging device 51 to the computer. This eliminates the need to lay LAN cables or the like when remotely monitoring a construction site. In this embodiment, the winch unit 3 can be remotely controlled by a computer at the construction office or the like while viewing the images captured by the imaging device 51 on a monitor at the construction office or the like. It is also possible to send instructions from the computer at the construction office or the like to a control unit (not shown) of the camera unit 5, remotely control the camera unit 5, and adjust the imaging range of the imaging device 51.

[0038] The rollers 56 are used to move the base 52 along the guide rail 2. The rollers 56 are arranged in grooves 22 on three sides of the rail member 20 except for the side opposite the camera unit 5, and move within these grooves 22. This allows the camera unit 5 to be raised and lowered in the vertical direction while maintaining the planar position of the base 52 (camera unit 5).

[0039] The rollers 57 contact the surface of the guide rail 2 and rotate as the camera unit 5 moves up and down. The rotation of the rollers 57 is detected by a sensor (not shown) such as a magnetic sensor, and a control unit (not shown) of the camera unit 5 issues an alarm from an alarm device 59 when the rotation of the rollers 57 is detected while the camera unit 5 is moving up and down.

[0040] The hook 58 is a hanging fixture for attaching the lower end of the wire 4 and is provided on the upper part of the camera unit 5 .

[0041] The alarm device 59 issues a visual or audible alarm, or both, when the camera unit 5 is raised or lowered, informing workers at the construction site of the presence of the camera unit 5 and its raising or lowering. The alarm device 59 is equipped with a speaker for issuing an audible alarm, such as a predetermined melody, and a flashlight or display for issuing a visual alarm. The alarm device 59 can also issue an alarm upon command from a computer at a construction office, etc., not only when the camera unit 5 is raised or lowered, but also when an abnormality is detected by remote monitoring. It is also possible for a computer at a construction office, etc., to process the images captured by the camera unit 5 and automatically issue an alarm, etc., depending on the results.

[0042] In this embodiment, wide-range video is captured by rotating (panning) the camera device 51 in a plane and rotating the arm member 53 in a plane. Fig. 6(a) is a diagram showing the positional relationship between the camera device 51 and the arm member 53 in a plane, and arrow c indicates the direction of the center of the range of photography by the camera device 51 (referred to as the photography direction). By rotating the camera device 51 from this state around the rotation axis 513, the photography direction c of the camera device 51 can be changed within a predetermined angle range.

[0043] In this embodiment, when the photographing direction c of the photographing device 51 reaches the end of the angle range, a marker 511 made of metal such as stainless steel and attached to the photographing device 51 is detected by the sensor 512, as shown in Fig. 6(b). Then, as shown in Fig. 6(c), the control unit (not shown) of the camera unit 5 rotates the arm member 53 around a rotation axis 531 at the end on the base 52 side in the same direction d as the rotation direction d of the photographing device 51 (see Fig. 6(b)). A pair of sensors 512 are provided on either side of the arm member 53, and the rotation direction d of the photographing device 51 can be determined by which sensor 512 detects the marker 511.

[0044] This allows the imaging direction c of the imaging device 51 to be changed beyond the aforementioned angle range, enabling monitoring of a wide area. It is also possible to capture images of the imaging range behind the camera unit 5 (the guide rail 2 side as seen from the camera unit 5), avoiding the base 52 and guide rail 2 behind the imaging device 51.

[0045] 7 is a diagram showing the underside of the charging unit 6. As shown in FIG. 7, the charging unit 6 has a substantially plate-shaped main body provided with a wireless charger 61, a recess 62, rollers 63, pins 64, etc. The charging unit 6 is suspended from above at two points by hanging members 25 such as wires, and is disposed without a fixed height. The upper end of the hanging members 25 is attached to the hanging members 24 at the upper end of the guide rail 2.

[0046] The wireless charger 61 charges the battery 54 of the camera unit 5.

[0047] The recess 62 is provided at the end of the main body plane of the charging unit 6 on the guide rail 2 side, and the wire 4 is passed through the recess 62. This makes it possible to set the camera unit 5 with the wire 4 attached on the guide rail 2, and then install the charging unit 6 on the guide rail 2 so as to cover the wire 4 from the outside.

[0048] The rollers 63 are used to move the charging unit 6 up and down along the guide rail 2. The rollers 63 are arranged in grooves 22 on two surfaces of the rail member 20, excluding the surface on the charging unit 6 side and the opposite surface, and run within these grooves 22. This allows the charging unit 6 to move up and down while maintaining its planar position.

[0049] The pin 64 is provided so as to protrude downward from the bottom surface of the charging unit 6 and is movable up and down. The pin 64 is for detecting contact with the camera unit 5.

[0050] That is, as shown in Figure 8, when the camera unit 5 reaches a predetermined height along the guide rail 2, the upper surface of the camera unit 5 comes into contact with the lower surface of the charging unit 6, pushing the pin 64 upward. When the control unit (not shown) of the charging unit 6 detects that the pin 64 has been pushed in, i.e., that the camera unit 5 has come into contact with the charging unit 6, it sends a message to the winch control unit via cable 35 that the camera unit 5 and the charging unit 6 have come into contact. This stops the winding of the wire 4. However, because the camera unit 5 cannot be stopped suddenly while rising, when the camera unit 5 comes into contact with the charging unit 6, the camera unit 5 pushes the charging unit 6 upward as shown by arrow e, and the hanging material 25 slackens slightly.

[0051] If the height of the charging unit 6 were fixed, there is a risk that the charging unit 6 would be damaged by the impact when the camera unit 5 comes into contact with the charging unit 6. However, in this embodiment, the charging unit 6 is supported by hanging without a fixed height, and is pushed up when it comes into contact with the camera unit 5, thereby absorbing the impact and preventing damage.

[0052] When the winch control unit of the winch unit 3 receives a signal indicating that the camera unit 5 and the charging unit 6 have come into contact, it stops winding the wire 4 as described above and also sends a signal to a computer at the construction office or the like indicating that the camera unit 5 is in the charging position. Charging of the battery 54 of the camera unit 5 via the wireless charger 61 of the charging unit 6 automatically begins when the charging unit 6 and the camera unit 5 come close to each other. The camera unit 5 may be configured to turn off the power to the photographing device 51 and the wireless communication device 55 when the start of charging (a change in voltage) is used as a trigger. This prevents discharge during charging. The heat dissipation mechanism 521 dissipates heat generated during charging by the charging unit 6.

[0053] The wire position adjustment mechanism 7 adjusts the planar position of the wire 4 extending from the winch unit 3 to match the planar position of the guide rail 2 when the planar positions of the winch unit 3 and the guide rail 2 (camera unit 5) differ. The wire position adjustment mechanism 7 is used by being attached to the single pipe 201 of the temporary scaffolding 200, but is not limited to this. It is also possible to attach and arrange it on a single pipe supported by the main body 100.

[0054] 9 is a diagram showing the wire position adjustment mechanism 7. The wire position adjustment mechanism 7 has a gripper 71, a first rail 72, a slider 73, a second rail 74, a pulley 75, and the like.

[0055] The gripping portion 71 grips the single pipe 201 and attaches the wire position adjusting mechanism 7 to the single pipe 201 .

[0056] The first rails 72 are arranged in two tiers, one above the other, so as to extend outward from the gripping portion 71. A second rail 74 is arranged above the first rail 72. The second rails 74 are rails that extend in a direction perpendicular to the first rail 72 in a plan view, and are arranged as a pair with a gap in the extension direction of the first rail 72 and are connected to each other.

[0057] Rail members similar to rail member 20 (see FIG. 2) are used for first rail 72 and second rail 74. Slider 73 is inserted into groove 721 of first rail 72 and is able to move along first rail 72. Slider 73 is fixed to each side of a pair of second rails 74, and as slider 73 moves along first rail 72, second rail 74 moves along first rail 72.

[0058] Pulley 75 is used to hang wire 4, and is arranged on second rail 74. A pair of pulleys 75 are arranged at a distance from each other in the longitudinal direction of second rail 74, and each is movable along second rail 74. Wire 4 hanging down from winch unit 3 is hung on one of pulleys 75, and wire 4 hanging down from the other pulley 75 is attached to camera unit 5.

[0059] By adjusting the orientation of the gripping portion 71, the extension direction of the first rail 72 can be changed, and by adjusting the position of the second rail 74 in the longitudinal direction of the first rail 72 and the position of each pulley 75 in the longitudinal direction of the second rail 74, the planar position of the wire 4 extending from the winch unit 3 can be adjusted to match the planar position of the guide rail 2.

[0060] As described above, the monitoring device 1 of this embodiment can monitor at different heights with a single camera by raising and lowering the camera unit 5 by winding and unwinding the wire 4. This eliminates the need to install a camera on each floor of a building, reducing installation time and the need to rearrange and remove cameras as construction progresses on each floor. Furthermore, the camera unit 5 is charged by the charging unit 6 at a predetermined height along the guide rail 2, significantly reducing the effort required to replace the camera unit 5's battery. Furthermore, the camera unit 5 does not require cables such as a power cord, eliminating interference between the cable and the wire 4 and eliminating the need for measures to prevent the cable from getting caught or tripping. Furthermore, the video captured by the camera unit 5 can be transmitted to a remote construction office or other location via the wireless communication device 55, eliminating the need for a LAN cable.

[0061] The monitoring device 1 of this embodiment remotely monitors a construction site, enabling construction progress confirmation, safety management, etc. to be performed immediately in real time, thereby realizing the aforementioned labor savings and work style reforms, etc. Furthermore, the rising and lowering camera unit 5 is easily recognized by workers, which helps maintain a sense of tension among workers.

[0062] Furthermore, in this embodiment, the charging unit 6 is suspended from above by a hanging material 25 and is installed above the camera unit 5 without a fixed height. As a result, as explained in Figure 8, etc., the impact when the camera unit 5 and the charging unit 6 come into contact can be mitigated, and damage to the charging unit 6 can be prevented.

[0063] In this embodiment, the wire 4 can be passed through the recess 62 of the charging unit 6, and the camera unit 5 below the charging unit 6 can be raised and lowered by the wire 4. Furthermore, because the wire 4 is passed through the recess 62 rather than a hole, it is possible to set the camera unit 5 with the wire 4 attached on the guide rail 2, and then install the charging unit 6.

[0064] Furthermore, in this embodiment, the wire position adjustment mechanism 7 can adjust the position of the wire 4 unwound from the winch unit 3 to match the guide rail 2 (camera unit 5), improving the degree of freedom in the installation position of the winch unit 3. Furthermore, by configuring the wire position adjustment mechanism 7 with the gripping portion 71, rails 72 and 74, and pulley 75, the wire position adjustment mechanism 7 is simplified, and the position of the wire 4 can be easily adjusted.

[0065] Furthermore, the guide rail 2 is constructed by attaching multiple upper and lower rail members 20 to a single pipe 201 of the temporary scaffolding 200 or a single pipe supported by the main body 100, so that the guide rail 2 of any height can be easily installed in the optimum location using the temporary scaffolding 200 or the main body 100.

[0066] 6 and other drawings, the camera unit 5 of this embodiment can capture images of a wide range by using the camera device 51 in combination with the rotation of the camera device 51 and the rotation of the arm member 53, thereby enabling wide-area monitoring. It is also possible to capture images of the range behind the camera unit 5, avoiding the base 52 and guide rail 2 behind the camera device 51.

[0067] Furthermore, the winch unit 3 of this embodiment is equipped with a wireless communication device 32 for remote control, which allows the camera unit 5 to be remotely raised and lowered. Such a camera unit 5 not only contributes to the work style reforms mentioned above, but also contributes to business continuity at the site by enabling unmanned checks of the damage status of buildings even if a disaster such as an earthquake or typhoon occurs at night or during business holidays.

[0068] In addition, in this embodiment, the alarm device 59 issues an alarm when the camera unit 5 is raised or lowered, which not only alerts the worker and prevents contact with the camera unit 5, but is also expected to be effective in improving the worker's safety awareness.

[0069] However, the present invention is not limited to the above-described embodiment. For example, in the above-described embodiment, the monitoring device 1 is installed between the temporary scaffolding 200 and the skeleton 100 by using the temporary scaffolding 200 installed along the skeleton 100. However, the monitoring device 1 can also be installed in a location other than between the temporary scaffolding 200 and the skeleton 100, such as an opening for an elevator provided in the skeleton 100 or an opening used as an atrium.

[0070] Furthermore, in this embodiment, the winch unit 3 is installed above the guide rail 2, but by providing a pulley or the like (not shown) to guide the wire 4, it is also possible to install the winch unit 3 in another location, such as on the floor below the guide rail 2. For example, by installing the winch unit 3 on the floor below the guide rail 2, there is no need to place heavy objects in high places. Furthermore, the winch unit 3 is easily accessible, making it suitable for manual operation.

[0071] Furthermore, the camera unit 5 is not limited to the above configuration. For example, in this embodiment, the camera unit 5 is provided with an alarm device 59, but by mounting an audio input / output device such as a microphone or speaker on the camera unit 5, audio communication can be carried out between a supervisor at a construction office or the like and a worker on-site. In addition, it is also possible to expand the range that can be monitored by the camera unit 5 by making the arm member 53 extendable or by making the entire camera unit 5 movable horizontally.

[0072] Furthermore, in this embodiment, the charging unit 6 is provided at the upper end of the guide rail 2 above the camera unit 5, but the charging unit 6 may also be provided at the lower end of the guide rail 2 below the camera unit 5. This allows for easier access to the charging unit 6, and simplifies maintenance of the charging unit 6. In this case, the wireless charger 61 should be provided on the top surface of the main body of the charging unit 6. However, if the winch unit 3 is provided above the guide rail 2 and the charging unit 6 is provided at the lower end of the guide rail 2, a separate power source (not from the winch unit 3) for the charging unit 6 will be required.

[0073] The monitoring device 1 of this embodiment is used at construction sites, but can also be used at construction sites that are being demolished.Furthermore, it can be used not only at construction sites, but also in buildings that are in use, such as factories, warehouses, music facilities, and sports facilities.

[0074] While the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to these examples. It is clear that those skilled in the art can conceive of various modifications or alterations within the scope of the technical ideas disclosed herein, and it is understood that these modifications also fall within the technical scope of the present invention.
