The power supply unit 175 is arranged adjacent to the drive unit 173, and contacts the electrode plate 8z (see FIG. 6) arranged on the inner surface of the duct rail 8 to supply power.

Since the supporting portions 170A and 170B have almost the same structure, the supporting portion 170B will be described here. The support portion 170B has a protruding plate 152b (an example of a plate) that is rotatable around a shaft 171b. The protruding plate 152b is formed of a round rectangular plate material. When the longitudinal direction of the protruding plate 152b is parallel to the longitudinal direction of the movable connecting portion 15, the width of the protruding plate 152b is substantially the same as the width of the movable connecting portion 15, and the protruding plate 152b corresponds to the movable connecting portion 15. It is in a state of being housed in the housing 15z. On the other hand, when the longitudinal direction of the protruding plate 152b is perpendicular to the longitudinal direction of the movable connecting portion 15, the width of the protruding plate 152b is wider than the width of the movable connecting portion 15, and the protruding plate 152b is larger than that of the movable connecting portion 15. It is in a state of protruding from the housing 15z. Openings 15z1 (see FIG. 5) through which the projecting plate 152b can project are formed on both side surfaces of the housing 15z. A protrusion 171c (see FIG. 4) is formed on the surface of the protrusion plate 152b so as to protrude in a direction perpendicular to a plane including a position eccentric from the shaft 171b (that is, +z direction).

The movable connecting portion 15 also has a long link plate 15y (see FIG. 4) and a short link plate (not shown) housed in the housing 15z. The link plate 15y is arranged along the supporting portion 170B and the power feeding portion 175 so as to engage with the supporting portion 170B and the power feeding portion 175, respectively, and is attached to the outer side in the longitudinal direction (−y direction in FIG. 4) by a spring member.

(See FIG. 4), a rounded rectangular opening (not shown) extending in the longitudinal direction through which a shaft (not shown) is inserted, and a short-side direction (that is, FIG. 4) through which a protrusion (not shown) is inserted. And a rounded rectangular opening (not shown) extending in the +x direction) is formed. The short link plate is long when the shaft 171a (see FIG. 2) of the projecting plate 152a is engaged with the opening of the short link plate and the projection of the projecting plate 152a is engaged with the opening of the short plate. Direction (that is, +y direction in FIG. 4). A push button 159A is attached to the short link plate on the side close to the end of the movable connecting portion 15. The push button 159A is exposed from the side of the housing 10z of the movable plug 10. The push button 159A is biased by a spring member (not shown), so that the short link plate is pulled inward in the longitudinal direction (-y direction in FIG. 4) when the user presses it with a finger, for example. ing.

The power supply unit 175 has a first power supply path including a power supply wheel 175z1, an arm portion 175x1, and a shaft 175y1 that makes contact with one of the electrode plates 8z in the duct rail 8 to form a power supply path. Further, the power feeding portion 175 has a second power feeding path including a power feeding wheel 175z2, an arm portion 175x2, and a shaft 175y2, which contacts the other electrode plate 8z in the duct rail 8 to form a power feeding path.

In the first energization path, the arm portion 175x1 can swivel around an axis 175y1 that is perpendicular to both the direction in which the housing 15z moves and the width direction of the housing 15z (+x axis or −x axis in FIG. 4). (That is, it is rotatable). The power feeding wheel 175z1 is a disk-shaped conductor rotatable about a shaft 175y1 and is rotatably attached to one end (tip) of the arm portion 175x1. The other end of the arm portion 175x1 is pivotally supported by the shaft 175y1. A winding spring 175w1 having one end fixed to the arm portion 175x1 and the other end fixed to the housing 15z is wound around the shaft 175y1. The spiral spring 175w1 urges the arm portion 175x1 and the power feeding wheel 175z1 connected to the arm portion 175x1 so as to push the arm portion 175x1 to the outside (−x direction in FIG. 4) of the housing 15z of the movable connecting portion 15. A protrusion 175z11 is formed on the surface of the arm portion 175x1 at a position eccentric from the rotation axis of the power feeding wheel 175z1.

In the second energization path, the arm portion 175x2 can pivot about an axis 175y2 that is perpendicular to both the direction in which the housing 15z moves and the width direction of the housing 15z (+x axis or −x axis in FIG. 4). (That is, it is rotatable). The power feeding wheel 175z2 is a disk-shaped conductor rotatable about a shaft 175y2, and is rotatably attached to one end (tip) of the arm portion 175x2. The other end of the arm portion 175x2 is pivotally supported by the shaft 175y2. A winding spring 175w2 having one end fixed to the arm portion 175x2 and the other end fixed to the housing 15z is wound around the shaft 175y2. The spiral spring 175w2 urges the arm portion 175x2 and the power feeding wheel 175z2 connected to the arm portion 175x2 so as to push the arm portion 175x2 to the outside (the +x direction in FIG. 4) of the housing 15z of the movable coupling portion 15. A protrusion 175z12 is formed on the surface of the arm portion 175x2 at a position eccentric from the rotation axis of the power feeding wheel 175z2.

The power feeding wheel 175z1 and the power feeding wheel 175z2 are arranged in the longitudinal direction of the movable connecting portion 15 so as to be separated from each other by a predetermined distance or more. As a result, the power feeding wheel 175z1 and the power feeding wheel 175z2 do not overlap in the width direction of the movable connecting portion 15. Therefore, it is possible to avoid the possibility that the power feeding wheel 175z1 and the power feeding wheel 175z2 are in contact with each other inside the movable coupling portion 15 to cause a short circuit. Further, the width of the movable connecting portion 15 can be reduced, and the movable connecting portion 15 can be easily mounted inside the duct rail 8. Further, the power feeding wheel 175z1 and the power feeding wheel 175z2 are biased so as to be pushed out in opposite directions from both side surfaces of the movable connecting portion 15. Even if one side surface of the movable connecting portion 15 comes into contact with a member having conductivity, the power feeding wheel 175z1 and the power feeding wheel 175z2 do not simultaneously come into contact with the member having conductivity, so that no short circuit occurs. Examples of the material of the power feeding wheels 175z1 and 175z2 include a copper alloy such as phosphor bronze having excellent spring properties, or nickel plated with gold having excellent conductivity.

On a surface of the link plate 15y facing the power feeding portion 175, a substantially Z-shaped opening 17y3 extending in the longitudinal direction exposing the shafts 175y1 and 175y2, a substantially triangular opening 17y4 into which the protrusion 175z11 is inserted, and A substantially triangular opening 17y5 into which the protrusion 175z12 is inserted is formed.

In the link plate 15y, the shaft 175y1 of the first energization path and the shaft 175y2 of the second energization path engage with the opening 17y3 of the link plate 15y, the projection 15z11 of the power supply wheel 175z1 engages with the opening 17y4, and the power supply wheel The protrusion 15z12 of 175z2 is movable in the longitudinal direction (+y direction in FIG. 4) while being engaged with the opening 17y5.

In the present embodiment, the electrode of the power feeding portion 175 that comes into contact with the electrode plate 8z of the duct rail 8 is a power feeding wheel that is a disk-shaped conductor that is rotatable around an axis, but the present invention is not limited to this. It may be a ball bearing or the like that performs rolling rotation.

The drive unit 173 has a gear 14z (see FIG. 6) connected to a motor (not shown) that is an actuator, and a pair of left and right drive wheels 141 and 142 pivotally supported by the rotation shaft of the gear 14z. Rubber members 141z and 142z having a large friction coefficient are attached to the outer circumferences of the drive wheels 141 and 142 so that the drive wheels 141 and 142 do not slip when moving while coming into contact with the inner wall of the duct rail 8. Further, the driving wheels 141 and 142 are arranged in the longitudinal direction so as to be separated from each other so that the movable plug 10 can easily travel on the curved duct rail 8.

FIG. 4 is an explanatory diagram of the turning operation of the support portion 170B of the movable connecting portion 15 and the power feeding portion 175. The swing operation of the support portion 170A is the same as the swing operation of the support portion 170B, and thus the description thereof is omitted. When the push button 159B of the movable connecting portion 15 is not pressed down, the longitudinal direction of the protruding plate 152b is orthogonal to the longitudinal direction of the movable connecting portion 15.

When attaching the movable plug 10 to the duct rail 8, the user presses the push buttons 159A and 159B of the movable connecting portion 15 all at once. When the push buttons 159A and 159B are pressed all at once, the link plate 15y moves in the longitudinal direction (the +y direction in FIG. 4) of the movable connecting portion 15 as the push buttons 159B are pressed (moved). At this time, the protrusion 171c formed on the protrusion plate 152b by being pressed by the opening 17y2 of the link plate 15y also moves in the longitudinal direction of the movable connecting portion 15 (+y direction in FIG. 4). Since the protrusion 171c is located at a position eccentric from the shaft 171b (obliquely upper right in FIG. 4), when the link plate 15y moves downward (+y direction in FIG. 4), the protrusion plate 152b moves as shown in FIG. Starting to turn around the shaft 171b in the direction of arrow ra in the figure. The movable connecting portion 15 transits from the state J1 to the state J5 in accordance with the amount of depression of the push button 159B.

In the state J5 in which the push button 159B is completely pressed, the longitudinal direction of the projecting plate 152b coincides with the longitudinal direction of the link plate 15y, and the width of the projecting plate 152b becomes substantially equal to the width of the housing 15z. Further, in the state J5 in which the push button 159B is completely pressed, the power feeding wheel 175z2 is also retracted so as to be housed in the housing 15z together with the turning of the protruding plate 152b. As a result, the width of the movable connecting portion 15 becomes a width that can be directly attached to the opening of the duct rail 8, so that the user can attach the movable connecting portion 15 inside the duct rail 8 in the Z direction.

When the user releases the depression of the push buttons 159A and 159B with the movable connecting portion 15 mounted inside the duct rail 8, the protruding plate 152b changes from the state J5 to the state J1 in the reverse order shown in FIG. And the state returns to the state of protruding from the opening 15z1 formed in the housing 15z. As a result, the lower surface of the protruding plate 152b is supported by the locking portions 8a1 and 8a2 (see FIG. 6) formed on the lower side of the duct rail 8. Since the movable connecting portion 15 is supported by the duct rail 8 and the movable plug 10 is attached to the duct rail 8, the movable plug 10 is movable in the duct rail 8.

Further, in the power feeding unit 175, when the push button 159B of the movable coupling unit 15 is not pressed, the arm unit 175x1 pivotally supported by the shaft 175y1 is biased to the outside of the housing 15z by the winding spring 175w1. The power feeding wheel 175z1 attached to the tip of the arm portion 175x2 projects from the opening 15z3 formed in the housing 15z. Similarly, the arm portion 175x2 pivotally supported by the shaft 175y2 is biased to the outside of the housing 15z by the winding spring 175w2. The power feeding wheel 175z2 attached to the tip of the arm portion 175x2 projects from the opening 15z4 formed in the housing 15z.

When the push button 159B is pressed and the link plate 15y moves in the longitudinal direction of the movable connecting portion 15 (the +y direction in FIG. 4), the power feeding wheel 175z1 transitions from the state J1 in FIG. 4 to the state J5, and the movable connecting portion is moved. Move to the inside of 15. At this time, the protrusion 175z11 formed on the arm portion 175x1 at the position eccentric from the rotation axis of the power feeding wheel 175z1 is located on the hypotenuse from the lower left corner of the substantially triangular opening 17y4 formed on the link plate 15y. You will be guided and move to the top vertex. Similarly, the power feeding wheel 175z2 moves to the inside of the movable connecting portion 15. At this time, the protrusion 175z12 formed on the arm portion 175x2 at a position eccentric from the rotation axis of the power feeding wheel 175z2 is located at the lower right corner of the substantially triangular opening 17y5 formed on the link plate 15y. Guide to the hypotenuse and move to the top.

In the state J5 in which the push button 159B is completely pressed, the power feeding wheel 175z1 and the power feeding wheel 175z2 are accommodated in the width of the housing 15z. Since the width of the movable connecting portion 15 is narrower than the width of the opening of the duct rail 8, the user can easily attach the movable connecting portion 15 to the inside of the duct rail 8.

When the user releases the push button 159B in a state where the movable connecting portion 15 is attached to the inside of the duct rail 8, the power feeding wheel 175z1 and the power feeding wheel 175z2 move from the state J5 to the state J1 in the reverse order shown in FIG. And the state returns to the state of protruding from the openings 15z3 and 15z4 formed in the housing 15z. Therefore, the power feeding wheel 175z1 and the power feeding wheel 175z2 are elastically urged toward the pair of electrode plates 8z provided inside the duct rail 8 to come into contact with the pair of electrode plates 8z and become energizable.

Although the mechanism of the support portion 170B of the movable connecting portion 15 and the power feeding portion 175 has been described here, the mechanism of the support portion 170A is the same as the mechanism of the support portion 170B.

FIG. 5 is an explanatory diagram showing a connected state of the movable plug 10 mounted on the duct rail 8. FIG. 6 is a sectional view showing the structures of the movable connecting portion 15 and the duct rail 8 in the connected state of FIG. The duct rail 8 has a long housing 8a whose cross section is formed in a substantially U shape. A pair of facing locking portions 8a1 and 8a2 are formed on the lower side of the duct rail 8 so that the movable connecting portion 15 can be housed in the opening of the duct rail 8. The width of the opening of the duct rail 8 corresponds to the distance between the pair of facing locking portions 8a1 and 8a2. Further, protrusions 8b1 and 8b2 are formed in the extending direction on the inner wall surfaces on both sides of the housing 8a. Electrode plates 8z, through which commercial AC is energized, are arranged in the extension direction on the tip surfaces of the protrusions 8b1 and 8b2. A ground electrode plate 8y is arranged in the extending direction on the ceiling surface inside the housing 8a.

The projecting plates 152a and 152b of the movable connecting portion 15 are supported by the locking portions 8a1 and 8a2 formed on the lower side of the duct rail 8, so that the movable plug 10 is suspended from the duct rail 8. .. Further, when the movable plug 10 is suspended from the duct rail 8, the outer peripheral surfaces of the drive wheels 141 and 142 contact the ceiling surface inside the duct rail 8. Therefore, when the drive wheels 141, 142 rotate, the movable plug 10 travels in the extension direction of the duct rail 8. Here, the drive unit 173 is formed as a unit in which the drive wheels 141 and 142, the gear 14z, and a motor (not shown) for supplying a drive force to the gear 14z are assembled. The drive wheels 141, 142 are driven by the above-mentioned motor (not shown) connected to the gear 14z.

The power supply wheel 175z1 and the power supply wheel 175z2 of the movable connecting portion 15 are in contact with and electrically connected to a pair of electrode plates 8z provided inside the duct rail 8, respectively, and are supplied with power from the electrode plates 8z. Although the ground electrode plate 8y is not used in the present embodiment, it may be used in consideration of the occurrence of leakage of the attachment 30 mounted on the movable plug 10. For example, a metal brush may be attached to the housing 15z so that the housing 15z of the movable connecting portion 15 is electrically connected to the ground electrode plate 8y.

The attachment 30 is attached to the device connecting portion 16. The attachment 30 attached to the device connecting portion 16 is movable along the duct rail 8 together with the movable plug 10. The device connecting portion 16 is divided into a pan member 121 and a tilt member 123. The pan member 121 includes a pan motor and a gear (not shown), and rotates the tilt member 123 in the pan direction. The tilt member 123 includes a tilt motor and a gear (not shown), and rotates the connected attachment 30 in the tilt direction.

FIG. 7 is a diagram showing the structure of the mounting portion 123z of the device connecting portion 16. The lower end of the device connecting portion 16 is formed into a mounting portion 123z for mounting the attachment 30. A recess 123y to which the attachment 30 is attached is formed on the lower surface of the mounting portion 123z. The housing 30z of the attachment 30 has a protrusion formed with a protrusion that fits into the recess 123y of the mounting portion 123z. The shape of the recess 123y of the mounting portion 123z is the same as the inside of the duct rail 8. On the inner wall surface of the recess 123y, a pair of protrusions 123w having communication terminals 123x for communicating with the attachment 30 arranged on the front surface are formed. Further, an electrode plate that supplies electric power acquired from each of the power supply wheels 175z1 and 175z2 is provided at a location (not shown) on the inner wall surface of the recess 123y. Further, the attachment 30 that can be mounted on the mounting portion 123z can be directly mounted on the duct rail 8. A general-purpose or existing attachment that can be attached to the duct rail 8 is also attached to the movable plug 10 to supply power. Therefore, a general-purpose or existing attachment, which has been used by being fixedly attached to the duct rail, can be moved along the duct rail, improving compatibility and expanding the range of use. In addition, since the number of types of attachments that can be attached to the movable plug increases, the utility value of the device management system 5 increases.

As described above, the movable plug 10 of the present embodiment has the housing 10z (an example of the main housing) that houses at least the control board 10k. The movable plug 10 is fixed by being connected to the housing 10z, and based on an instruction from the control unit 11 mounted on the control board 10k, extension of the duct rail 8 on which the electrode plate 8z (an example of a power supply line) is arranged. It has the movable connection part 15 (an example of a sliding part) which slides and moves along a direction. The movable plug 10 has a device connecting portion 16 (an example of a connecting portion) to which the one end side is connected and fixed to the housing 10z, and the other end side is attached with the attachment 30. The movable connecting portion 15 has a power feeding portion 175 that receives power from the electrode plate 8z and feeds power to the control board housed in the housing 10z. An elastic force is applied to the power supply wheel 175z1 of the power supply unit 175 in the direction of the electrode plate 8z so that the power supply wheel 175z1 can contact the electrode plate 8z.

As a result, the movable plug 10 can move smoothly along the duct rail 8 on which the electrode plate 8z is arranged, and reduces the friction at the time of contact with the duct rail 8 regardless of whether it is moving or not, and is accurate. Power can be supplied.

The movable connecting portion 15 is arranged above the housing 10z and is configured by a substantially rectangular parallelepiped housing 15z having a width less than the width of the opening of the duct rail 8 laid on the ceiling surface. Accordingly, the width of the movable connecting portion 15 is shorter than the width of the opening of the duct rail 8, so that the movable connecting portion 15 can be mounted inside the duct rail 8 to move the movable plug 10.

In addition, the power feeding unit 175 is configured by a pair of power feeding wheels 175z1 and 175z2 (an example of a disc-shaped conductor) that are spaced apart from and correspond to the pair of electrode plates 8z that are disposed inside the duct rail 8. To be done. As a result, the power supply wheels 175z1 and 175z2 can contact the electrode plate of the duct rail 8 while rotating. Therefore, when the movable plug 10 moves, the electrode plate 8z of the duct rail 8 and the power supply wheels 175z1 and 175z2 are less likely to wear due to frictional force, and the energized state can be maintained. In addition, the life of the power feeding unit 175 can be extended.

Further, the movable connecting portion 15 has supporting portions 170A and 170B that support the housing 10z and the device connecting portion 16 by being urged outward and engaging with the duct rail 8. The housing 10z is a push button 159A for restricting the protrusion of the power feeding portion 175 and the supporting portions 170A and 170B that is larger than the width of the housing 15z and storing the housing 10z within the width of the housing 15z in synchronization in response to a user operation. , 159B (an example of an operation unit). This allows the user to easily push the pushbuttons 159A and 159B to retract the power supply wheels 175z1 and 175z2 of the power supply unit 175 and the projecting plates 152a and 152b of the support units 170A and 170B, respectively, and easily inside the duct rail 8. The movable connecting portion 15 of the movable plug 10 can be attached to the.

Further, the casing 15z is longer than the casing 10z in the extension direction of the duct rail 8, and the supporting portions 170A and 170B are arranged outside the casing 10z. Thereby, the movable plug 10 can be stably supported by the duct rail 8. Further, at the time of mounting, the user can visually check whether or not the projecting plates 152a and 152b can be inserted into the duct rail 8 without seeing from the bottom.

Further, the movable connecting portion 15 includes a drive unit that integrally houses the drive wheels 141 and 142 that travel on the duct rail 8 and the gear 14z (an example of an actuator) that drives the drive wheels 141 and 142. The drive unit also includes a motor (not shown) that is connected to the gear 14z and supplies a driving force for rotating the gear 14z. This makes it possible to omit fine adjustment of the drive wheels and the gear 14z when adjusting the movable plug 10 so that the movable plug 10 can travel by abutting the drive wheels on the ceiling surface on the side opposite to gravity, and the adjustment can be simplified.

The support portion 170B is disposed on the end side of the housing 15z and is perpendicular to the moving direction of the housing 15z and the width direction of the housing 15z (+x axis or −x axis in FIG. 4). It has a rounded-rectangular projecting plate 152b that is rotatable about a shaft 171b. The projecting plate 152b is rotated so that the longitudinal direction of the projecting plate 152b is perpendicular to the longitudinal direction of the housing 15z and is turned parallel to the longitudinal direction of the housing 15z by operating the push buttons 159A and 159B. It is accommodated in the width of the body 15z. Thereby, when the movable plug 10 is mounted on the duct rail 8, the supporting portions 170A and 170B can be easily housed inside the duct rail 8.

Further, the power feeding unit 175 is arranged in the housing 15z, and axes 175y1 and 175y2 perpendicular to the moving direction of the housing 15z and the width direction of the housing 15z (+x axis or −x axis in FIG. 4), respectively. It has arm portions 175x1 and 175x2 that are respectively rotatable about the center of the center of FIG. 2 and rotatable feed wheels 175z1 and 175z2 (an example of a disc-shaped conductor) that are attached to the ends of the arm portions 175x1 and 175x2. Each of the arm portions 175x1 and 175x2 of the power feeding wheels 175z1 and 175z2 is urged toward the outside of the housing 15z, and is swung to the inside of the housing 15z by the operation of the push button 159B to rotate the width of the housing 15z. Housed in. Thereby, when the movable plug 10 is mounted on the duct rail 8, the power feeding portion 175 can be easily housed inside the duct rail 8.

The shape of the mounting portion 123z on the other end side of the device connecting portion 16 to which the attachment 30 is attached is received inside the duct rail 8 (engaged side) with which the movable connecting portion 15 engages. As a result, the versatile attachment 30 or the existing attachment 30 that can be attached to the duct rail 8 can be attached to the movable plug 10. In other words, it is expected that the operation of the device management system 5 according to this embodiment will be expanded.

The management server 50 receives the detection information detected by the attachment 30 from the attachment 30 connected to the movable plug 10 via the communication unit 53.

In the device management system 5, it is important for the user to know which attachment 30 is attached to which movable plug 10. In other words, when the user operates the movable plug 10 and the attachment 30 with the single operation terminal 40 and it is not associated with which attachment 30 is connected to which movable plug 10, each movable plug 10 is operated. Therefore, the work of individually operating the attachments 30 becomes complicated, resulting in reduced convenience. Here, a case is shown in which the user recognizes the operation of the attachment 30 mounted on the movable plug 10 and the movable plug 10 by looking at the operation screen GM1 displayed on the touch panel 44 of the operation terminal 40.

FIG. 10 is a diagram showing the operation screen GM1 displayed on the touch panel 44 of the operation terminal 40. On the operation screen GM1 displayed on the touch panel 44, two pieces of attachments as the attachments 30 and pair information of the movable plugs 10 to which the respective attachments are connected are shown. Note that the operation screen GM1 may show k (k: an integer of 2 or more) pieces of pair information instead of two pieces of pair information.

A display frame w1 regarding the attachment (ID=N1) is displayed on the left side of the operation screen GM1. The attachment (ID=N1) is a light. In the display frame w1, the plug ID (ID=1) of the movable plug 10 to which the attachment N1 is attached is shown. The display frame w1 also shows the current position, brightness, irradiation direction, and operation button bt1 of the movable plug 10 (ID=1) to which the attachment (ID=N1) is attached. Here, the current position pn is schematically drawn as a red circle on the duct rail. Note that the configuration of the position detection sensor 18 in the movable plug 10 may be omitted if, for example, the setting that does not need to display the current position is made according to the user's operation.

Similarly, a display frame w2 regarding the attachment (ID=N2) is displayed on the right side of the operation screen GM1. The attachment (ID=N2) is a sensor. The display frame w2 shows the plug ID (ID=2) of the movable plug 10 to which the attachment (ID=N2) is attached, that is, the corresponding plug. Further, in the display frame w2, the current position of the movable plug 10 (ID=2) to which the attachment (ID=N2) is attached, sensing information, and the operation button bt2 are shown.

In this way, on the operation screen GM1, information regarding the attachment with the device ID=N1 and information regarding the attachment with the device ID=N2 are displayed separately. Therefore, for example, when the user wants to move the light, which is the attachment with the device ID=N1, from the current location to another location, it can be determined that the movable plug 10 with the plug ID=1 should be selected and moved. ..

Next, an operation in which the management server 50 manages the attachment 30 attached to the movable plug 10 will be shown. Here, the movable plug 10 and the attachment 30 are respectively assigned a plug ID and a device ID in advance. Two-dimensional codes representing the plug ID and the device ID are attached to the housing 10z of the movable plug 10 and the housing 30z of the attachment 30, respectively.

(First operation example)
FIG. 11 is a sequence diagram showing a first operation example of the device management system 5. The communication unit 53 of the management server 50 communicates with the communication unit 13 of the movable plug 10 and the communication unit 33 of the attachment 30, respectively, and acquires the plug ID of the movable plug 10 and the device ID of the attachment 30 (T1). The control unit 51 registers the acquired plug ID of the movable plug 10 and the device ID of the attachment 30 in the management table 52z, and associates the movable plug 10 with the attachment 30. The management table 52z may be registered/updated at any timing. Although a plurality of plug IDs and device IDs have been acquired, it is not known at this point which movable plug 10 the attachment 30 is connected to.

The camera 45 of the operation terminal 40 captures an image of the movable plug 10 and the attachment 30 attached to the movable plug according to a user operation (T2). The captured image includes the two-dimensional code of the plug ID and the device ID. The communication unit 43 of the operation terminal 40 transmits image data including the captured plug ID of the movable plug 10 and the device ID of the attachment 30 to the management server 50 (T3).

The communication unit 53 of the management server 50 receives the image data transmitted from the operation terminal 40. The control unit 51 analyzes the received image data, reads the plug ID and the device ID included in the image data (T4), associates these with each other, and updates the management table 52z held in the memory 52 (T5). .. The control unit 51 generates the operation screen GM1 in which the movable plug 10 and the attachment 30 in which the plug ID and the device ID are associated with each other are paired (T6). The communication unit 53 transmits the screen data of the generated operation screen GM1 to the operation terminal 40 (T7). The communication unit 53 also receives an operation command from a user operation from the operation terminal 40. The operation screen GM1 generated here shows the correspondence between the movable plug 10 and the attachment 30 as shown in FIG. 10, for example, but the operation screen generated before the association is performed is the movable plug 10 and the attachment 30. The individual operation screens that are not associated with each other may be arranged side by side.

The communication unit 53 of the management server 50 transmits the operation command received from the operation terminal 40 to the movable plug 10 and the attachment 30 (T8). When the communication unit 13 of the movable plug 10 receives the operation command, the control unit 11 instructs the movable connecting unit 15 to perform an operation such as movement start/stop according to the operation command. Similarly, when the communication unit 33 of the attachment 30 receives the operation command, the control unit 31 performs an operation such as changing the illumination amount or the illumination direction in the case of a light, according to the operation command.

As described above, the connected device management method in the device management system 5 includes the device management system 5 including two or more movable plugs 10, two or more attachments 30, and the management server 50 (an example of the connected device management system). Executed by. The management server 50 acquires the identification information (for example, the device ID) of each of the at least one set of the movable plug 10 and the attachment 30 connected to the movable plug 10 and stores the identification information in the memory 52. The management server 50 generates an operation screen GM1 (an example of a display screen) indicating a connection correspondence relationship between each pair of the movable plug 10 and the attachment 30, and transmits the operation screen GM1 to the operation terminal 40 to display it on the touch panel 44 of the operation terminal 40. ..

Therefore, the device management system 5 allows the management server 50 to easily confirm the display screen showing the connection correspondence relationship between the movable plug 10 and the attachment 30 forming each pair on the operation terminal 40 owned by the user, User convenience can be improved.

Further, in the first operation example of the connected device management method in the device management system 5, the management server 50 captures k pairs of one attachment 30 and one movable plug 10 as a subject as an operation terminal 40. A captured image sent from (an example of a user terminal) is acquired. The management server 50 creates a display screen based on this captured image. As a result, the device management system 5 can associate the movable plug 10 with the attachment 30 based on the image captured by the camera 45 of the operation terminal 40. Therefore, the user operation is simple.

(Second operation example)
In the first operation example, the user performs an image capturing operation, but in the second operation example, a case is shown in which the movable plug 10 and the attachment 30 are associated with each other without being operated by the user. In addition, the housing 10z of the movable plug 10 and the housing 30z of the attachment 30 do not have to be provided with the two-dimensional code representing the plug ID and the device ID.

FIG. 12 is a sequence diagram showing a second operation example of the device management system 5. The communication unit 53 of the management server 50 communicates with the communication unit 13 of the movable plug 10 and the communication unit 33 of the attachment 30, respectively, and acquires the plug ID of the movable plug 10 and the device ID of the attachment 30 (T11). The control unit 51 registers the acquired ID of the movable plug 10 and device ID of the attachment 30 in the management table 52z, and associates the movable plug 10 with the attachment 30. The management table 52z may be registered/updated at any timing.

The control unit 31 of the attachment 30 detects that the movable plug 10 has been attached by the sensor 34 (T12). This detection may be performed at any timing while the attachment 30 is attached to the movable plug 10, or may be performed when the user attaches the attachment 30 to the movable plug 10. The communication unit 33 of the attachment 30 transmits the device ID to the movable plug 10 (T13).

The communication unit 13 of the movable plug 10 receives the device ID transmitted from the attachment 30 via the communication terminal 123x (T14). The communication unit 13 of the movable plug 10 transmits data including the received device ID and the plug ID of the own device to the management server 50 (T15).

As described above, the connected device management method in the device management system 5 includes a plurality of k (k: an integer of 2 or more) movable plugs 10, k attachments 30, and a management server 50. 5 (an example of a connected device management system). The management server 50 acquires the plug IDs of the k movable plugs 10 (an example of identification information) and the device IDs of the k attachments 30 and stores them in the memory 52. The management server 50 acquires a captured image sent from the operation terminal 40 (an example of a user terminal) that captures k pairs of one attachment 30 and one movable plug 10 as subjects. Based on this captured image, the management server 50 generates an operation screen GM1 (display screen) showing the connection correspondence relationship of each pair of the movable plug 10 and the attachment 30, and transmits the operation screen GM1 to the operation terminal 40 to transmit the operation terminal 40. It is displayed on the touch panel 44. When each attachment 30 detects a connection with any of the movable plugs 10 forming a one-to-one pair, it sends its own device ID (an example of first identification information) to the movable plugs 10 forming a pair. Each movable plug 10 sends the device ID sent from the attachment 30 forming a pair and its own plug ID (an example of the second identification information) to the management server 50 in association with each other. The management server 50 generates an operation screen GM1 (an example of a display screen) showing the connection correspondence relationship of each pair of the movable plug 10 and the attachment 30 based on the information sent from each movable plug 10 to generate an operation terminal. 40 (user terminal) for display.

Therefore, in the second operation example of the device management system 5, the device management system 5 can associate the movable plug 10 with the attachment 30 without the user's operation. Therefore, the user can save the trouble of managing the movable plug 10 and the attachment 30 attached thereto. Further, the camera 45 of the operation terminal 40 can be omitted.

Note that the association between the plug ID of the movable plug 10 and the device ID of the attachment 30 is performed by the user directly inputting the plug ID and the device ID via the touch panel 44 of the operation terminal 40, and then the management server 50 is notified. It may be transmitted.
