In addition, the unmanned construction site management system according to an embodiment of the present invention can recognize an ignition source such as cigarette fire occurring at a construction site using information collected by a camera and a sensor unit and cope with a fire in advance. On-site workers can be managed through awareness of the number of people entering and exiting.

1 is a schematic diagram of a construction site unmanned management system according to an embodiment of the present invention. 1, a construction site unmanned management system 100 according to an embodiment of the present invention includes a main body 120 including a rail unit 110, a camera 122 and a sensor unit 124, and a management unit 132 ) And a management module 130 having a monitoring unit 134.

The rail unit 110 may be installed on the ceiling of a construction site. The rail unit 110 may be expanded and installed in a two-dimensional manner on the ceiling of a construction site. For example, in the case of an apartment construction site, in order to monitor and manage the construction site while running the main body 120 between several rooms or areas, the rail unit 110 includes a plurality of rooms arranged in different areas in a plan view. It can be extended in two dimensions to cover.

The body 120 may be installed to be driven along the rail unit 110. The main body 120 may collect information for monitoring various problem situations occurring in a construction site while moving between a plurality of rooms or areas. The main body 120 may include a camera 122 for photographing an image of a construction site and a sensor unit 124 for detecting at least one of smoke and sound of the construction site.

The main body 120 in which the camera 122 and the sensor unit 124 are installed continuously moves around various rooms of the construction site along the rail unit 110 installed on the ceiling, and various information such as site image data, smoke information, sound information, etc. Can be obtained. In an embodiment, the sensor unit 124 may include a smoke detection sensor that detects smoke at a construction site, and a sound detection sensor that detects sound indicating abnormal signs (fire, collision sound, etc.) of the construction site.

In this way, by attaching the smoke detection sensor and the sound detection sensor to the main body 120, the monitoring performance for blind spots that cannot be detected can be improved by using the image acquired by the camera 122, and the monitoring function can be supplemented. . For example, a fire can be prevented in advance through a smoke detection sensor, and by analyzing the acoustic signals collected using a sound detection sensor, it detects abnormal collision sounds that are directly connected to personal accidents, noise complaints and disasters occurring in the field. Therefore, it is possible to respond to problems occurring at the construction site more quickly by sending the notification to the remote manager.

The management module 130 may be installed in the main body 120 or may be provided in a remote location such as an external server. The management unit 132 of the management module 130 may analyze the image photographed by the camera 122 to recognize the number of persons entering the building at the construction site and manage workers. The management unit 132 may recognize the number of persons entering and exiting each area of the construction site based on the location information of the main body 120 and the worker recognition information. The management unit 132 may manage a worker by recognizing an identification symbol marked on a work clothes or a hard hat in an image, for example.

The monitoring unit 134 of the management module 130 is based on the information detected by the camera 122 and the sensor unit 124, and various construction site events related to personal accidents and disasters (fire, etc.) by area of the construction site. Can be monitored. For example, the monitoring unit 134 may detect an ignition source in an image and, when an ignition source is detected in the image, may generate a fire alarm for an area in which the ignition source is detected during a construction site.

When smoke is detected by the smoke detection sensor, the monitoring unit 134 may generate a fire alarm for an area where smoke is detected during a construction site. In addition, when a sound indicating an abnormal symptom is detected by the sound detection sensor, the monitoring unit 134 may generate an alarm for an area in which a sound indicating an abnormal symptom is detected during a construction site. In an embodiment, the monitoring unit 134 compares the combination of information collected by the camera 122 and the sensor unit 124 with the abnormal event information stored in the database, and detects an event indicating an abnormal symptom when they match, It can trigger an alarm.

Figure 2 is a flow chart of a construction site unmanned management method according to an embodiment of the present invention. 1 and 2, when the unmanned management system starts to operate, the camera 122 acquires image information of a construction site in real time, and the sensor unit 124 includes a plurality of smoke detection sensors and sound detection sensors. It detects information such as smoke/sound of construction sites in real time using sensors, and continuously monitors potential construction site disasters (S10~S16).

In an embodiment, the unmanned construction site management system may recognize a fire occurring indoors at the construction site using the camera 122. The construction site unmanned management system may detect a fire by recognizing an ignition source using RGB pixel values of a flame from, for example, an image acquired by the camera 122. In an embodiment, when the camera 122 for photographing a construction site recognizes that a pixel value in a red area is greater than a threshold value while collecting image data, it may recognize the size and determine whether or not there is a flame. Since it is not possible to accurately determine whether or not a flame occurs only in the red area in the image, it is possible to increase the accuracy of recognizing the fire occurring at the construction site by detecting the pixel value in the gray area in the image and checking the presence or absence of smoke generated in the event of a fire. .

If the image-processed information photographed by the camera 122 detects a worker's smoking or other ignition situation, the unmanned management system activates an alarm or immediately transmits the image information to the management server to perform fire prevention operations. Can start (S17). In addition, even when the smoke detection sensor detects smoke equivalent to a fire or when the sound detection sensor detects a collision sound equivalent to human damage, an alarm is generated and abnormal event occurrence information is transmitted to the management server (S18).

Even if it is judged that the camera's image processing result and the sensor's detection result are not comparable to the abnormal event, the unmanned management system combines the information of the three sensors and processes the signal to determine the occurrence of the abnormal event once more. It is determined whether or not an abnormal event has occurred according to the result of the fusion (S19~S21). That is, the detection unit 134 creates a heuristic database between the sensor value and the actual occurrence of an abnormal event, and uses the image of the camera 122 to merge the values of the smoke detection sensor and the sound detection sensor.

Even when the image processing result of the camera 134 and the values of the smoke and sound detection sensors are all less than the threshold, the empirical database and the sensor values are compared, and in the case of a combination of the values corresponding to the occurrence of an abnormal event, an alarm operation is performed, and the control server The information can be transmitted to (S22). In addition, it is possible to update the empirical database by recording the combination of the sensor value obtained while operating the unmanned management system and the actual occurrence of an abnormal event, and use it for future construction site monitoring (S23).

3 and 4 are views illustrating a rail part constituting the unmanned construction site management system according to an embodiment of the present invention. In an embodiment, the camera 122 and the sensor unit 124 along the rail unit 110 monitor the construction site while moving the construction site, and the camera 122 and the sensor unit ( By using the information collected by 124), it is possible to minimize the manpower to supervise the construction site and significantly reduce the cost of supervision during construction. In addition, by monitoring the construction site from a remote location, sufficient intensive management of the quality and safety of the building becomes possible.

5 is a view illustrating a transfer rail and a connecting member of a rail unit constituting the unmanned management system for a construction site according to an embodiment of the present invention. The rail unit 110 may be composed of a transfer rail and a connecting material. The transfer rails can be extended by combining the connecting member, and the connecting member has four types of straight, curved, or cross-shaped shown in Figs. 5A to 5D, and the straight rail branch shown in Fig. 5E. Device. Therefore, using various types of connecting materials, the main body 120 can be driven in a straight line, a curved line, and a cross run along the rail unit 110 at a construction site.

6 and 7 are views illustrating a rail part constituting the unmanned construction site management system according to an embodiment of the present invention. Referring to FIGS. 6 and 7, the rail unit 110 may include a first straight rail 112 and a second straight rail 114 and a rail branching device 116 before a straight crossing. The first straight rail 112 may be arranged in the first direction (X). The second straight rail 114 may be arranged in a second direction Y perpendicular to the first direction X. The rail branching device 116 before the straight crossing of the first straight rail 112 and the second straight rail 114 to cross-run the main body 120 between the first straight rail 112 and the second straight rail 114 It can be provided at the intersection.

In an embodiment, the straight rail branching device 116 may include a turntable 116a and a rotation driving part 116c that rotates the turntable 116a by 90°. The turntable 116a may be provided at an intersection between the first straight rail 112 and the second straight rail 114. The turntable 116a may include a third straight rail 116b that can be connected to the first straight rail 112 or the second straight rail 114 depending on whether or not it rotates.

The orthogonal rail rotating apparatus 116 may support to diverge the driving direction by changing the driving direction of the main body 120 by 90° in the cross driving position. The rail branch device 116 before the straight church is provided with a command of either straight forward or 90° rotation in communication with the main body 120, for example, the turntable 116a from the state shown in FIG. 6 to the state shown in FIG. 7 By rotating 90°, the driving direction of the main body 120 can be changed. Through this, it is possible to select the movement trajectory of the main body 120 according to the environment of the construction site, and by securing the maximum monitoring area of the construction site, which is mainly composed of a bundle of several rooms, the construction site is concentrated with the minimum number of cameras. Can be managed.

8 is a configuration diagram of a driving unit and a location recognition unit constituting a construction site unmanned management system according to another embodiment of the present invention. 1 and 8, the unmanned construction site management system may include a driving unit 140 and a location recognition unit 150. The driving unit 140 may include a driving wheel installed in the main body 120 and a driving motor for driving the main body 120 along the rail unit 110 by rotating the driving wheel. The position recognition unit 150 may include an encoder installed on the driving motor to measure the number of rotations of the driving motor. The position recognition unit 150 may recognize the position of the main body 120 based on the number of rotations of the driving motor measured by the encoder.

The position recognition unit 150 updates the position of the main body 120 with preset coordinate information when detecting the crossing point detection unit 152 for detecting the rail branching device 116 before the orthogonal church, and the rail branching device 116 before the orthogonal crossing. It may include a location update unit 154 for correcting an error of the encoder based on a difference value between the location information of the main body 120 and the updated coordinate information. That is, by placing a camera between the wheel and the body, it is possible to recognize the connecting material and to recognize the absolute coordinates each time the connecting material passes. The construction site unmanned management system can grasp the location of the main body and the current construction location through the encoder of the motor, and through this, it is possible to arrive at the planned location under construction and shoot the construction site.

If the equipment is operated using only the motor encoder, the approximate position can be grasped, but the position may be misaligned as errors accumulate. In order to prevent this, a sensor (a camera or sensor) may be added between the main body 120 and the wheel to recognize the rail branch device 116 in front of the cross-section. Through this, when the main body 120 moves along the rail, it recognizes the rail branching device 116 before orthogonal crossing, and whenever it passes the rail branching device 116 before the crossing, a certain absolute coordinate can be obtained.

As soon as the main body 120 reaches the rail branch device 116 before orthogonal crossing, the absolute coordinate information is automatically transmitted to the main body 120 and the error can be corrected by updating the main body position value to the correct absolute position. Based on this, the error of the encoder can be corrected. For example, if the moving distance of the main body 120 calculated based on the measured value of the encoder is larger than the moving distance of the main body 120, the weight reflected in the measured value of the encoder is increased in proportion to the difference value. The position of the main body 120 may be calculated, and in the opposite case, the position of the main body 120 may be calculated by reducing the weight reflected in the measured value of the encoder.

In this way, by recognizing the absolute position of the main body 120 through the recognition information of the rail branch device 116 before the direct church, it is possible to prevent the accumulation of positional information errors of the main body 120, and the location of the problem situation at the construction site. You can accurately recognize and respond effectively. In another embodiment of the present invention, a camera or a sensor is installed on the rail branch device 116 before the straight church to recognize the approach of the main body 120, and when the main body 120 is recognized, the corresponding information is provided to the position recognition unit to provide a location. It is also possible to have to update.

The unmanned construction site management method according to an embodiment of the present invention can be written as a program that can be executed on a computer, for example, and can be implemented in a general-purpose digital computer that operates the program using a computer-readable recording medium. .
