[0073] As shown in FIGS. 4 to 8, the monitoring system according to the present invention may further include an alarm device (140) that signals the occurrence of an emergency accident while operating under the control of a control unit (120) and a support device (150) installed to support the alarm device (140).

[0074] The alarm device (140) may be configured to have its operating state controlled according to a control signal transmitted from the control unit (120), and may be configured to include at least one of a warning sound generator (141) that operates according to an emergency accident occurrence signal transmitted from the control unit (120) to generate a warning sound, and a light signal generator (142) that visually indicates an emergency situation through a light signal.

[0075] The warning sound generator (141) can be configured in the form of a siren or a buzzer and can generate a constant volume or periodic warning sound.

[0076] The light signal generator (142) can generate a flashing or illuminating light signal to allow the worker to visually recognize the emergency situation.

[0077] The alarm device (140) can be activated by receiving an emergency accident signal from the control unit (120) and provide immediate audiovisual feedback to field workers and managers.

[0078] The control unit (120) determines whether an emergency accident has occurred based on an abnormal state or a stopped state of movement of a moving object detected through the camera (110), and can activate an alarm device (140) installed in a section or an adjacent area where it is determined that an accident has occurred.

[0079] Accordingly, the alarm device (140) can generate an alarm so that a worker can immediately recognize a dangerous situation in the section where an emergency accident is detected or in an adjacent area, and can enable the worker to respond quickly and for response measures to be taken by the manager.

[0080] The alarm device (140) can be linked with the control unit (120) and the server to record the alarm occurrence history and operating status, thereby enabling safety management and accident history analysis of the factory work environment.

[0081] The support device (150) can perform support and position adjustment functions so that the alarm device (140) can be placed in an optimal position corresponding to the work environment of each section within the factory.

[0082] The support device (150) may include a base plate (160) that is stably seated and fixed to the inner floor surface of the factory, a fixing plate (170) on which an alarm device (140) is installed on the front, a horizontal moving part (180) that supports the fixing plate (170) so that it can move in the front and rear directions to adjust the front and rear position of the alarm device (140), and a vertical moving part (190) that supports the horizontal moving part (180) from the base plate (160) so that it can move in the up and down directions to adjust the height of the alarm device (140).

[0083] The base plate (160) can be made in the shape of a plate and can be stably seated and fixed on the inner floor surface of the factory while having rigidity capable of supporting a certain load.

[0084] Accordingly, the base plate (160) can support the load of the support device (150) and alarm device (140) installed on the upper part, thereby allowing the entire structure to be installed stably.

[0085] The base plate (160) may be provided with a seating pad (161) on its lower surface.

[0086] The mounting pad (161) can be made of an elastic material such as silicone or rubber, and when in contact with the inner floor surface of the factory, it can increase friction to prevent the base plate (160) from sliding on the floor surface.

[0087] Additionally, the mounting pad (161) can partially absorb vibrations or shocks transmitted from the outside to ensure stable support of the support device (150) and the alarm device (140).

[0088] Accordingly, the mounting pad (161) can improve the positional stability of the alarm device (140) by maintaining a stable fixed state of the base plate (160) even in a vibration environment caused by the operation of internal factory equipment.

[0089] The vertical moving part (190) may include a support (191) whose lower part is fixed to the upper surface of the base plate (160) and whose upper part is open, a lifting bar (192) whose lower part is connected to the upper inner side of the support (191) so as to be movable up and down and whose upper part is fixed to the horizontal moving part (180), and a fixing means (193) for fixing the lifting bar (192) to the support (191).

[0090] The vertical movement unit (190) may be formed as a single unit, but may be formed as multiple units and arranged in the front-rear direction on the upper part of the base plate (160) to support the horizontal movement unit (180) more stably.

[0091] The support (191) can be in the shape of a square tube with the top and bottom open, and the bottom can be fixed integrally to the upper surface of the base plate (160).

[0092] The lifting bar (192) can have a shape corresponding to the internal shape of the support (191) and can be inserted into the inside of the support (191) and coupled so as to be slidable in the up and down direction.

[0093] A guide hole (191a) extending in an upward and downward direction may be formed on one side of the support (191).

[0094] The fixing means (193) may include a fixing member (194) having one end fixed to one side of the lower part of the lifting bar (192) and the other end protruding to the outside of the support (191) by passing through the guide hole (191a), and a fixing member (195) screw-coupled to the other end of the fixing member (194).

[0095] The fixing member (194) has screw threads formed on its outer surface, and the fixing member (195) has screw threads formed on its inner surface, so that they can be screw-coupled to the fixing member (194).

[0096] The guide hole (191a) can guide the vertical movement of the lifting bar (192) and, at the same time, limit the range of movement of the fixing member (194) to prevent the lifting bar (192) from detaching from the support (191).

[0097] The fixed member (195) can cause the lifting bar (192) to be pressed against one side of the inner side of the support (191) according to the tightening rotation, thereby maintaining the lifting bar (192) in a fixed state relative to the support (191). Through this, the height of the horizontal moving part (180) and the alarm device (140) can be stably maintained at a set position.

[0098] To this end, the lifting bar (192) may be provided with a contact pad (not shown) on one side.

[0099] The contact pad may be made of an elastic material such as silicone or rubber, and by adhering to the inner surface of the support (191), it can more stably fix the position of the lifting bar (192) and prevent the position of the lifting bar (192) from changing due to external vibration or impact.

[0100] The fixed member (195) can enable the lifting bar (192) to move up and down as it is separated from the inner surface of the support (191) according to the release rotation.

[0101] As a result, the alarm device (140) can be installed at an appropriate height corresponding to the internal equipment layout and working environment of the factory through the operation of the fixed member (195), and can have visibility so that the worker can more easily recognize the emergency situation.

[0102] The horizontal moving part (180) may include a support frame (181) comprising a top plate (182) that is positioned at the rear of the fixed plate (170) and fixed to the upper part of the lifting bar (192), and a pair of side plates (183) that extend upward from both sides of the top plate (182); a moving bar (184) whose front end is fixed to the rear of the fixed plate (170) and whose rear end is received inside the front end of the support frame (181); and a moving means (185) installed inside the support frame (181) so as to be positioned at the rear of the moving bar (184) and which moves the moving bar (184) in the forward and backward directions according to driving.

[0103] The support frame (181) can form a 'U' shape with the top plate (182) and side plates (183) formed integrally, with the top open.

[0104] Accordingly, the support frame (181) can stably position the moving bar (184) and the moving means (185) inside, while protecting them from external impacts or the ingress of foreign substances.

[0105] The moving bar (184) can be configured to move integrally with the fixed plate (170) on which the alarm device (140) is installed while being seated on the top plate (182), and can be formed to be able to slide in the forward and backward directions within the support frame (181).

[0106] Accordingly, the moving bar (184) can be adjusted so that the position of the alarm device (140) can be adjusted in the forward and backward directions, thereby improving visibility and recognition according to the alarm occurrence location.

[0107] The moving means (185) may be made of a cylinder and may be connected to the rear end of the moving bar (184) while being positioned on the rear inner side of the support frame (181). The moving means (185) may be configured to move the moving bar (184) in the forward and backward directions by the extension and contraction of the rod when driven.

[0108] The moving means (185) can be operated by the control of the control unit (120), and the alarm device (140) can be moved in the forward and backward directions together with the fixed plate (170).

[0109] The means of movement (185) can be controlled so that the alarm device (140) moves in the direction of the corresponding section based on emergency accident occurrence section information transmitted from the control unit (120).

[0110] Accordingly, the alarm device (140) can be moved in the direction of the location where an emergency accident is detected in each section of the factory to more effectively transmit the alarm to workers and managers, and to more smoothly confirm the location of the emergency accident.

[0111] In addition, the horizontal movement unit (180) can adjust the installation position of the alarm device (140) to suit the working environment, thereby allowing it to flexibly respond to various equipment layout structures inside the factory, and can improve the visibility of the alarm device (140) and the alarm transmission efficiency.

[0112] The horizontal movement unit (180) may further include a guide means (186) for guiding the forward and backward movement of the movement bar (184).

[0113] The support frame (181) may have a movable hole (181a) formed on both sides that extends in the front-rear direction.

[0114] The moving hole (181a) can be formed in the side plate (183) and can guide the rear end of the moving bar (184) to move in the forward and backward directions while being stably supported by the guide means (186).

[0115] The moving bar (184) may have a connecting projection (184a) formed at the rear end, and a groove (184b) may be formed on the rear surface of the connecting projection (184a).

[0116] The guide means (186) may include a guide bar (187) in which the central part is connected to and fixed by the groove (184b) and connected to the moving means (185), and both ends protrude to both sides of the support frame (181) through the moving hole (181a), and a wheel (188) which is rotatably fixed to the guide bar (187) so as to be positioned on both sides of the connecting projection (184a).

[0117] The guide bar (187) can be moved in the forward and backward directions together with the moving bar (184) as the central part is connected to and fixed in the groove (184b) according to the driving of the moving means (185).

[0118] The wheel (188) can be rotatably fixed to the guide bar (187) so as to be positioned on both sides of the connecting projection (184a) and seated on the top plate (182).

[0119] The wheel (188) rotates by contact with the top plate (182) when the moving bar (184) moves according to the driving of the moving means (185), and can make the movement of the moving bar (184) smoother.

[0120] Accordingly, the guide means (186) can stably support the rear end of the moving bar (184) on the support frame (181) while simultaneously allowing the forward and backward movement of the moving bar (184) to be more smoothly driven by the operation of the moving means (185).

[0121] The support device (150) may further include a protection means (200) for protecting the horizontal moving part (180).

[0122] The protective means (200) may include a protective cover (201) which is connected to the outside of the rear end of the support frame (181) with the lower and front and rear ends open, and a protective plate (202) which has its rear end integrally fixed to the upper side of the front end of the protective cover (201) and has its front end extended forward and seated on the upper side of a pair of side plates (183).

[0123] The protective cover (201) can be connected to the outer side of the rear end of the support frame (181) while forming a 'U' shape with an open bottom, and can protect the means of transport (185) from the outside.

[0124] The protective cover (201) can be attached to the outside of the support frame (181) so as to be positioned at the rear of the movement hole (181a) so as not to interfere with the movement of the guide bar (187).

[0125] The protective plate (202) is seated on the upper part of the support frame (181) in front of the protective cover (201) and can protect the moving means (185) and the guide means (186) from the outside.

[0126] The protective means (200) may be configured to have a separate device, such as a camera (110), installed on the upper surface.

[0127] As a result, the protective means (200) can protect the horizontal moving part (180) from external impact or foreign matter, and at the same time enable the placement and installation of the camera (110) even in an environment where it is difficult to have a separate wall or structure for fixing or installing the camera (110) in the internal space of the factory.

[0128] In addition, by allowing a camera (110) to be installed together with the protection means (200), the work area can be photographed more effectively in conjunction with the location of the alarm device (140), and the situation at the site can be identified more accurately in the event of an emergency.

[0129] Accordingly, the support device (150) can adjust the height and front-to-back position of the alarm device (140) to enable optimal installation corresponding to the structure and working environment of the factory, while simultaneously improving the protection and installation convenience of the related device, thereby improving the safety and operational efficiency of the smart factory working environment monitoring system.

[0130] The above description is merely an example of an embodiment for implementing a smart factory work environment monitoring system according to the present invention.
