Description

[Technical field]

[0001] The present invention relates to a safety management system that is installed in a factory, a logistics warehouse, etc., photographs a limited area, determines whether an object detected within the photographed area is authorized, and performs an entrance / exit control function, sets a priority order for passing objects, and controls physical blocking devices and notification devices based on the set priority order to restrict the passage of objects with lower priority. [Background technology]

[0002] In general, in places such as factories and logistics warehouses, the movement of work vehicles and pedestrians to transport goods occurs frequently. If a collision occurs between two work vehicles, between a work vehicle and a pedestrian, or between a work vehicle and goods placed on the roadway during such movement, not only human life will be lost, but also economic losses will occur due to damage to goods.

[0003] Therefore, in places where goods are frequently transported, a safe signal system is needed to protect work vehicles and workers, and in this regard, the applicant has filed an application for "Logistics and Vehicle Movement Route Safety Signal Management Apparatus and Method" (hereinafter referred to as "Patent Document 1").

[0004] The aforementioned Patent Document 1 has a feature of setting priority passage for work vehicles and pedestrians in order to safely and quickly adjust the movement flow of work vehicles and pedestrians in response to congestion of work vehicles and pedestrians that occurs in a limited movement space, and controlling the logistics of goods for priority pedestrians and securing passageways within the vehicle movement route.

[0005] However, although the above-mentioned Patent Document 1 has the advantage of being able to use existing sensing equipment to sense the conditions on the roadway, it requires various types of sensors and vehicle-specific sensing equipment, such as a loop coil, that is installed on the ground to sense the work vehicle.

[0006] In addition, vehicle-specific detection equipment requires difficult and time-consuming maintenance as well as on-site construction, and there is a problem in that during maintenance, the passage of work vehicles on the relevant road must be restricted until the maintenance is completed.

[0007] For the reasons mentioned above, since multiple sensing signals are received via various types of sensors, a more complicated control algorithm is required to integrate these signals and perform safety management.

[0008] In particular, the ability to remotely monitor and control complex control algorithms is required. Summary of the Invention [Problem to be solved by the invention]

[0009] In order to solve the above problems, the present invention aims to provide a safety management system that identifies and detects objects in real time using cameras such as CCTVs, rather than various types of sensors and vehicle-specific detection equipment, sets entry priorities for detected objects, and controls physical barrier devices and notification devices based on the set priorities to restrict the passage of objects with lower priorities. [Means for solving the problem]

[0010] A safety management system according to an embodiment of the present invention includes an intersection safety management means including a safety management photographing module that photographs a limited area, a safety management detection module that detects objects entering the area and detects object information, a safety management shielding module that is located within the area and physically controls the movement of the object, a safety management notification module that is located near the area and provides a visual or audio alarm, and a safety management control module that receives object information from the safety management detection module, sets an object passage priority based on the object information, and controls the safety management shielding module and the safety management notification module based on the set priority to restrict the passage of objects with a second or lower priority; a wireless device that is provided in the object and receives information regarding the alarm from the safety management control module; and a relay device that enables the transmission and reception of information between the safety management control module and the wireless device.

[0011] In this case, the relay device is characterized in that it has multiple connections to one or more wireless communication devices located in the intrusion detection area.

[0012] The safety management shooting module generates a video frame for a shooting area, and calculates video information by linking the video frame with metadata including time information and position information.

[0013] The safety management detection module is provided in the safety management photography module and includes a safety management area setting unit that forms a plurality of detection areas in a photography area, a safety management object detection unit that detects an object entering the detection area, a safety management judgment unit that judges the validity of the object detected by the object detection unit, and a safety management database unit in which object information for judging the validity of the safety management judgment unit is stored.

[0014] The detection area formed by the safety management area setting unit includes an entry detection area for detecting the initial entry of the object, determining the validity of the detected object, and approving the entry permission of the determined object, an entry waiting area for waiting until the object exits, and a direction detection area for detecting the moving direction of the object that has passed through the entry waiting area.

[0015] The safety management database unit stores authorized wireless device identification numbers, and the safety management judgment unit compares the wireless device identification number of an object that has entered the intrusion detection area with the identification number stored in the safety management database unit to judge the validity of the object.

[0016] The safety management control module receives object information detected by image analysis of the image frames from the safety management detection module, links the object information that has been approved for entry permission to the image information, and stores the linked object information and image information in a database as priority judgment information.

[0017] The safety management determination unit calculates the available space size of the entry waiting area and the number of waiting objects, and compares the calculated values ​​with a preset space size and the number of objects.

[0018] At this time, the safety management control module controls the safety management shielding module and the safety management safety module according to a comparison result between the calculated value and a preset value so that the object can exit through the direction detection area.

[0019] The safety management shielding module includes an approach path shielding unit that physically controls the object's entry into an approach waiting area, and an intersection shielding unit that physically controls the object's entry into a direction detection area.

[0020] In this case, when an object exits from the entry waiting area in the direction of the direction detection area, the safety management control module closes the intersection shielding unit if the number of objects passing through the direction detection area matches the number of objects calculated by the safety management judgment unit. Effect of the Invention

[0021] A safety management system according to an embodiment of the present invention detects objects within a limited area via a photography module and a detection module provided on one side of the photography module, and if there is an abnormality in the photography module or the detection module, the module can be replaced rather than performing maintenance on site, thereby shortening the maintenance time on site and shortening the time that work vehicle passage is restricted due to maintenance.

[0022] Also, by being multiple-connected to a plurality of wireless devices located within the intrusion detection area, it is possible to quickly determine whether an object is permitted to enter the area based on the identification number of the wireless device.

[0023] In addition, through priority determination information linked to metadata including time information and location information, entry time information of multiple work vehicles detected simultaneously in multiple entry road areas can be quickly collected and managed sequentially, making it possible to set priorities more accurately.

[0061] 6 is a diagram illustrating a configuration of a safety management detection module 122 according to an embodiment of the present invention. Referring to this figure, the safety management detection module 122 includes a safety management area setting unit 122a, a safety management object detection unit 122b, a safety management determination unit 122c, and a safety management database unit 122d.

[0062] The safety management area setting unit 122a forms a plurality of detection areas in the area photographed by the approach road photographing unit 121a.

[0063] FIG. 7 is a diagram showing a plurality of detection areas formed by the safety management area setting unit 122a.

[0064] Referring to this, the plurality of detection areas include an entry detection area A1 for detecting the initial entry of an object, determining the validity of the detected object, and approving the entry permission of the determined object, an entry waiting area A2 for waiting until the object exits the intersection, and a direction detection area A3 for detecting the moving direction of an object that has passed through the entry waiting area A1.

[0065] The safety control object detector 122b can track and detect objects entering the detection area, and can also detect flames, smoke, and the like within the detection area.

[0066] The safety management judgment unit 122c can determine the object identification detected by the safety management object detection unit 122b and the validity (hereinafter, "second validity") of the detected object regarding entering the intersection, and calculate the number of work vehicles located within the entry waiting area A2 and the available space size.

[0067] The second validity refers to whether the work vehicle is qualified to enter the intersection when the detected object is a work vehicle. That is, when the detected object is not a work vehicle but a pedestrian, a bicycle rider, etc., the safety management determination unit 122c may not determine the second validity.

[0068] In addition, the safety management determination unit 122c can compare the number of work vehicles located in the entry waiting area A2 with a preset number of vehicles, and can compare the usable space size in the entry waiting area A2 with a preset waiting space size.

[0069] The safety management database unit 122d includes the type and number of the work vehicle for the second validity determination, and identification information for the wireless device 200 installed in the work vehicle.

[0070] The safety management shielding module 123 includes an entry path shielding unit 123a that physically controls the entry of objects into the entry waiting area A1, and an intersection shielding unit 123b that physically controls the entry of objects into the direction detection area A3.

[0071] The safety management notification module 124 provides visual and auditory information to objects, and includes an entry path notification unit 124a that is installed on one side of the entry waiting area A2 and provides information to objects attempting to enter the entry waiting area A2, and an intersection notification unit 124b that is installed on one side of the direction detection area entry waiting area A3 and provides information to objects attempting to enter the intersection.

[0072] The information provided by the access path notification unit 124a may include access permitted, access not permitted for unauthorized work vehicles, access not permitted for work vehicles entering from other directions, prohibition of movement by other objects other than work vehicles within the access path, and waiting to enter due to failure to determine validity.

[0073] The information provided by the intersection notification unit 124b may include exit permission, exit not permitted for work vehicles approaching from other directions, and movement prohibited for other objects other than work vehicles within the intersection.

[0074] The safety management control module 125 receives object information detected by image analysis of the image frame from the safety management detection module 122, and links the object information that has been approved for entry permission with the image information calculated from the safety management shooting module 121.

[0075] Additionally, the linked object information and image information are organized into a database as priority determination information.

[0076] In addition, the safety management control module 125 sets the object's passage priority based on the entry time information of the object into the entry waiting area A2 stored in the priority judgment information, and controls the safety management shielding module 123 and the safety management notification module 124 based on the set priority to restrict the passage of work vehicles with the next priority or lower.

[0077] In addition, when an object such as a pedestrian, bicycle, or object is detected in the intersection area instead of a work vehicle, the safety management control module 125 controls the safety management shielding module 123 and the safety management notification module 124 in all access road areas based on the detected information to restrict the passage of the work vehicle.

[0078] In addition, if an object such as a pedestrian, bicycle, or object is detected in the approach road area rather than a work vehicle, the safety management shielding module 123 and safety management notification module 124 in the approach road area are controlled based on the detected information to restrict the passage of the work vehicle.

[0079] In addition, the safety management control module 125 can receive identification information for the wireless device 200 held by the object via the first relay device 310 and the second relay device 320, and transmit alarm information generated by the safety management notification module 124 to the wireless device 200.

[0080] In addition, when the safety management detection module 122 detects a fire, smoke, or the like at the entrance side of the access control area, the safety management control module 125 can transmit the detected information to a central system.

[0081] FIG. 8 is a diagram showing a state in which the approach path shielding portion 123a is opened when a work vehicle enters the approach detection area A1 according to an embodiment of the present invention.

[0082] FIG. 9 is a diagram illustrating a process in which the approach path shielding unit 123a is controlled by the safety management control module 125 when a work vehicle enters the approach detection area A1 according to an embodiment of the present invention.

[0083] Referring to these figures, when the safety management detection module 122 installed on the access road R1 identifies an object that has entered the access detection area A1 as a work vehicle, it makes a second validation determination as to whether the work vehicle is an object authorized to enter.

[0084] When the wireless device 200 is located within the ingress detection area A1, the second relay device 320 attempts to connect to the wireless device.

[0085] Alternatively, when an object is detected in the intrusion detection area A1 by the safety control object detection unit 122a, a connection may be attempted with the wireless device 200 located in the intrusion detection area A1.

[0086] At this time, the second relay device 320 located at the intersection or the approach road area is preferentially connected to the wireless device 200 installed in the work vehicle, but if there are multiple work vehicles and pedestrians in the approach detection area A1, it can be simultaneously connected to the multiple wireless devices 200 carried by the work vehicles and pedestrians. And the connection is maintained until the object leaves the intersection or the approach road area.

[0087] If the work vehicle attempting to enter the entry detection area A1 is a work vehicle authorized for entry, the safety management object detection unit 122a detects the work vehicle and available space located within the entry waiting area A2 and transmits the detected information to the safety management judgment unit 122b.

[0088] Based on the received sensing information, the safety management judgment unit 122b compares the number of work vehicles in the entry waiting area A2 with a preset number of vehicles, and compares the usable space size with a preset waiting space size.

[0089] As shown in FIG. 8, when the number of work vehicles is less than a preset number of vehicles and the available space size in the entry waiting area A2 is greater than the preset waiting space size, the entry road shielding portion 123a is opened.

[0090] At this time, the safety management object detection unit 122a continues to track and detect objects in the shooting area, but when a work vehicle permitted to enter the entry waiting area A2 enters the entry waiting area A2, it transmits the entry time and vehicle number of the work vehicle to the safety management control module 125. Then, when the work vehicle passes through the entry detection area A1, the entry path blocking unit 123a is closed.

[0091] If the number of work vehicles is greater than the preset number of vehicles, or if the available space size in the entry waiting area A2 is smaller than the preset waiting space size, the entry road shielding unit 123a continues to be closed. Then, when the intersection shielding unit 123b installed on the entry road R1 is opened and then closed, the safety management determination unit 122b again compares the number of work vehicles and the available space size in the entry waiting area A2 with the preset values.

[0092] FIG. 10 is a diagram illustrating a process of checking whether an object is permitted to enter when a work vehicle enters the entry detection area A1 according to an embodiment of the present invention.

[0093] 2, the second relay device 320 is connected to at least one wireless device 200 located within the entrance detection area A1.

[0094] When the work vehicle that has entered the entry detection area A1 is unauthorized, the safety management control module 125 maintains the closed state of the entry road shielding unit 123a, and visually and audibly provides the unauthorized work vehicle with entry denial information via the entry road notification unit 124a. Then, the entry denial information is also transmitted to the wireless device 200.

[0095] The safety management object detection unit 122a tracks and detects an unauthorized work vehicle located within the entry detection area A1, and if the work vehicle is not detected in the detection area, the second relay device 320 disconnects the connection with the wireless device 200 of the work vehicle.

[0096] The safety management determination unit 122b determines a second validity of the other work vehicle detected within the entrance detection area A1.

[0097] FIG. 11 is a diagram showing a state in which the intersection shielding portion 123b is opened when a work vehicle enters the direction detection area A3 based on the highest priority order according to an embodiment of the present invention.

[0098] FIG. 12 is a diagram illustrating a process in which the intersection shielding part 123b is controlled when a work vehicle enters the direction detection area A3 based on the highest priority according to an embodiment of the present invention.

[0099] Referring to these figures, a safety management detection module 122 installed on the access road R1 detects work vehicles entering the access waiting area A2 and calculates the number of work vehicles waiting in the access waiting area A2.

[0100] In addition, the safety management control module 125 sets a priority by comparing the entry time information of the work vehicle sensed through the priority judgment information with the entry time information of the work vehicle on other entry roads stored in advance.

[0101] In addition, when the entry time of the work vehicle received from the safety management detection module 122 of the approach road R1 is faster than the entry time of the work vehicle at the approach roads R2 to R4, the safety management control module 125 maintains the intersection shielding portion 123b of the approach roads R2 to R4 in a closed state and opens the intersection shielding portion 123b of the approach road R1.

[0102] If the entry time of the entry road R1 is next, the intersection shielding portion 123b of the entry road R1 is kept closed.

[0103] After the intersection shielding portion 123b of the approach road R1 is opened, the safety management object detection portion 122a tracks and detects the work vehicle moving from the approach waiting area A2 to the direction detection area A3.

[0104] Furthermore, when the number of work vehicles passing through the entry waiting area A2 and moving into the direction detection area A3 becomes equal to the number of work vehicles waiting in the entry waiting area A2, the intersection shielding portion 123b of the entry road R1 is closed.

[0105] FIG. 13 is a diagram showing a state in which the intersection shielding portion 123b and the approach road shielding portion 123a on the other approach roads are opened when a work vehicle exits according to the highest priority order according to an embodiment of the present invention.

[0106] FIG. 14 is a diagram illustrating a process in which an intersection shielding portion 123b on another entrance road is controlled when a work vehicle exits according to the highest priority order according to an embodiment of the present invention.

[0107] Referring to these figures, the access road R1 is set as the highest priority for entering the intersection, the intersection shielding portion 123b of the access road R1 is opened by the safety management control module 125, and at least one work vehicle located in the entry waiting area A1 of the access road R1 moves to the access roads R2 and R3.

[0108] At this time, when the intersection shielding part 123b is opened, the safety management control module 125 closes the approach road shielding part 123a and the intersection shielding part 123b located in the remaining approach roads except for the approach road where the opened intersection shielding part 123b is located.

[0109] When the work vehicle tracked and detected by the safety management object detection unit 122a is detected in the direction detection area A3 of another approach road, rather than the approach road where the opened intersection shielding unit 123b is installed, the intersection shielding unit 123b of the detected approach road is opened.

[0110] In addition, information that a work vehicle entering from another direction is unable to exit is provided audibly and visually to work vehicles waiting in the entry waiting area A2 of the entry road via the intersection notification unit 124b and the wireless device 200.

[0111] In addition, when the number of work vehicles tracked and detected by the safety management object detection unit 122a is equal to the number of vehicles that have entered the entry waiting area A2 in the exit direction, the safety management control module 125 stops operation of the intersection notification unit 124b and closes the intersection shielding unit 123b.

[0112] FIG. 15 is a diagram illustrating a process in which the approach road shielding unit 123a in another approach road is controlled when a work vehicle exits according to the highest priority order according to an embodiment of the present invention.

[0113] In reference to this, when a work vehicle tracked and detected by the safety management object detection unit 122a enters the entry waiting area A2, the safety management control module 125 opens the entry path blocking unit 123a and provides audible and visual information to the work vehicle waiting and entering the entry detection area A1 via the entry path notification unit 124a and the wireless device 200 that entry is not permitted by a work vehicle entering from another direction.

[0114] When the number of work vehicles tracked and detected by the safety management object detection unit 122a is equal to the number of vehicles passing in the exit direction after entering the entry detection area A1, the safety management control module 125 stops operation of the entry path notification unit 124a and closes the entry path blocking unit 123a.

[0115] FIG. 16 is a diagram illustrating a process of controlling a traffic restriction for a work vehicle by the intersection safety management means 120 when detecting an object such as a pedestrian or an object, rather than a work vehicle, in an intersection area according to an embodiment of the present invention.

[0116] In reference to this, when the safety management detection module 122 detects an object such as an object or pedestrian other than a work vehicle within the area photographed by the approach road photographing unit 121a or the intersection photographing unit 121b, or detects a work vehicle that has stopped for a previously set stopping time, the safety management detection module 122 transmits the detection information therefor to the safety management control module 125.

[0117] As shown in FIG. 16, when an object is detected within the shooting area of ​​the intersection shooting unit 121b, the safety management control module 125 closes the intersection shielding unit 123b installed on the approach roads R1 to R4, and provides visual and audible information to the work vehicle waiting in the approach waiting area A2 via the intersection notification unit 124b and the wireless device 200.

[0118] In this manner, the safety management control module 125 controls the safety management shielding modules 123 and the safety management notification modules 124 installed at the entrances R1 to R4 based on the transmitted sensing information.

[0119] The scope of the present invention should be interpreted as including all modifications and variations derived based on the technical concept of the present invention in addition to the embodiments disclosed herein. [Industrial Applicability]

[0120] The safety management system of the present invention is installed in locations where work vehicles and workers pass through, and can control traffic flow within the workplace by setting priorities for passing objects and restricting the passage of objects with the next priority or lower.

[0121] In other words, the present invention not only enables rapid transport of goods by preventing traffic congestion by controlling the traffic flow between work vehicles within business premises such as factories, warehouses, and logistics centers, but also prevents safety accidents caused by collisions between work vehicles and workers that occur every year.

[0122] Therefore, since the present invention is a technology that can create demand in various industries such as manufacturing, construction, and warehousing, it is expected to have extremely high industrial applicability. [Explanation of symbols]
