Description

  The present invention relates to a designated range monitoring system that monitors the entry of a person, a vehicle, or the like into a designated range at a construction site.

  Conventionally, when working with high-altitude work vehicles for construction of overhead wires or construction / civil engineering vehicles, it is necessary to prevent people and other vehicles from entering the hazardous area around the vehicle. , The monitor was assigned to monitor. However, in the case of monitoring with monitoring personnel, there are cost problems due to labor costs and safety problems due to human error.

  In addition, as a method for monitoring intruders, detection methods such as pre-installed power lines, ultrasonic waves, infrared rays, etc., when the detection object is disconnected or shielded, or suspicious persons are detected based on temperature differences using an infrared camera. There was something to do. However, in the case of detection due to disconnection or shielding of energized wires, ultrasonic waves, infrared rays, etc., or detection due to temperature difference using an infrared camera, the equipment is expensive, the installation is troublesome, or the detection area is limited. There was.

  On the other hand, as a work safety monitoring system for construction / civil engineering work vehicles, Patent Document 1 discloses that camera video data around a work vehicle is acquired by a camera, and that the maximum range of motion assuming an operation error by an operator is determined as a dangerous region. An invention is described in which the determined dangerous area is superimposed on the camera video data and displayed on the image monitor. However, in the case of the invention described in Patent Document 1, since the maximum range of motion that assumes an operator's turning operation or arm operation error is determined as the dangerous region, the monitoring range can be set freely.

  On the other hand, as a system for monitoring the intrusion of a person or another vehicle into a designated range around the vehicle, the present inventors realize in Japanese Patent Application No. 2014-044621 at a low cost with a simple system configuration. At the same time, a specified range monitoring system that allows the monitoring range to be set freely is proposed.

  This designated range monitoring system includes an imaging device, a control device, and an alarm device. The imaging device captures an image of the surroundings of the vehicle from above, and setting means provided in the imaging device or the control device. Sets the designated range to be monitored within the shooting range by the shooting device, detects that a person or other vehicle has entered the specified range set by the detection means provided in the shooting device or control device, and intrudes Information is transmitted, and an alarm device receives intrusion information and issues an alarm.

  In the designated range monitoring system proposed in Japanese Patent Application No. 2014-044621, when setting the designated range to be monitored in the photographing range by the photographing apparatus, in addition to the method performed based on the operation of the operator, the designated range is arranged in the photographing range. We propose a method for recognizing the set sign (safety cone etc.) However, it takes time for image processing to recognize the difference in color and shape between a setting sign such as a safety cone and other parts in an image taken by a photographing apparatus, and there remains a problem in accuracy. .

  The present invention solves the above-described conventional problems, and in a designated range monitoring system for monitoring the entry of a person or a vehicle into a designated range at a construction site, when a designated range is set using a setting sign In addition, the processing time is shortened and the accuracy is improved.

  In order to solve the above problems, a designated range monitoring system according to the present invention includes a photographing device, a control device, and an alarm device, and designates a designated range for monitoring the entry of a person, a vehicle, or the like into a designated range at a construction site. In the system, the photographing device photographs the construction site from above, and a setting unit provided in the photographing device or the control device includes a designated range to be monitored within a photographing range by the photographing device. The detection means provided in the photographing device or the control device detects that a person or vehicle has entered the specified range, and transmits intrusion information. The intrusion information is received and an alarm is given, and the setting means recognizes the blinking of the light emitting member attached to the setting mark arranged in the photographing range and sets the specified range.

  When a vehicle is arranged at a construction site, a designated range may be set around the arranged vehicle. In this case, the “vehicle” includes an aerial work vehicle for construction of overhead lines and a construction / civil engineering vehicle (such as an excavator car), a transportation truck, a passenger car, and the like.

  In the specified range monitoring system of the present invention, the imaging device takes a picture of the construction site from above, and setting means provided in the imaging device or the control device sets the specified range of the monitoring target within the imaging range by the imaging device. Therefore, the monitoring range can be freely set according to the use situation. In addition, since the detection means provided in the imaging device or the control device detects that a person or vehicle has entered the specified range and transmits the intrusion information, a conductive line, ultrasonic wave or infrared ray is used to detect the intrusion. It is not necessary to install a generator, an infrared camera or the like, and can be realized at a low cost with a simple system configuration. And since an alarm device receives intrusion information and alarms, it can notify reliably the invasion of a person, a vehicle, etc. to a specified range.

  In addition, since the setting means recognizes the blinking of the light emitting member attached to the setting mark arranged in the photographing range and sets the designated range, the setting mark can be recognized accurately in a short time.

  As described above, according to the present invention, in the designated range monitoring system for monitoring the entry of a person or a vehicle into the designated range at the construction site, when the designated range is set using the setting sign, the processing time is shortened. And accuracy can be improved.

  Next, the designated range monitoring system according to the embodiment of the present invention will be described with reference to FIGS. First, the configuration of the designated range monitoring system 100 according to the present embodiment will be described with reference to FIG.

  A designated range monitoring system 100 according to the present embodiment is a system that monitors the entry of a person or another vehicle into a designated range around a vehicle at a construction site. The designated range monitoring system 100 includes an imaging device 1, a control device 2, and an alarm device 3. It is configured. The imaging device 1, the control device 2, and the alarm device 3 are connected to the network 4 and can transmit and receive information via the network 4. The network 4 may be wired or wireless, but can be appropriately selected according to the usage status of the system.

  The imaging device 1 captures an image of the surroundings of the vehicle from above, and image information captured by the imaging device 1 is transmitted to the control device 2 via the network 4.

  The control device 2 is a terminal device having a display screen such as a tablet terminal, for example, and the image information transmitted from the photographing device 1 is displayed on the display screen of the control device 2. In addition, the control device 2 has a built-in program having an image processing function, and an operator can perform an input operation to arbitrarily set a designated range to be monitored within the displayed shooting range. ing. Note that setting of the designated range within the photographing range can be performed by a conventionally known image processing program. As described above, the control device 2 is provided with setting means for setting the designated range to be monitored within the photographing range of the photographing device 1.

  Furthermore, the control device 2 detects that a person or another vehicle has entered the set designated range based on the image information sent from the photographing device 1 by the image processing function of the built-in program. Can be done. It should be noted that the detection of intrusion of a person or other vehicle into the set designated range can be performed by a conventionally known image processing program. Then, when it is detected that a person or another vehicle has intruded, the intrusion information is transmitted to the alarm device 3 via the network 4. As described above, the control device 2 is provided with detection means for detecting that a person or another vehicle has entered the set designated range and transmitting intrusion information.

  Note that the setting means for setting the designated range to be monitored within the shooting range by the shooting device 1 can be configured to be provided in the shooting device 1 instead of the control device 2. When the photographing device 1 is provided with setting means, a dedicated camera incorporating a conventionally known image processing program capable of realizing the function of the setting means is used and designated based on the operation information of the operator transmitted from the control device 2 Set the range. On the other hand, when the control unit 2 includes the setting unit, a conventionally known image processing program capable of realizing the function of the setting unit is incorporated in the control unit 2, and a general camera is used as the shooting device 1 for shooting. The configured image information is transmitted to the control device 2.

  Similarly, a detection unit that detects that a person or another vehicle has entered the set designated range and transmits intrusion information can also be configured to be provided in the photographing apparatus 1 instead of the control apparatus 2. . When the imaging device 1 is provided with the detection means, intrusion information is transmitted to the alarm device 3 using a dedicated camera incorporating a conventionally known image processing program capable of realizing the function of the detection means. On the other hand, when the control means 2 is provided with the detection means, a conventionally known image processing program capable of realizing the function of the detection means is built in the control apparatus 2, and a general camera is used as the photographing apparatus 1 for photographing. The configured image information is transmitted to the control device 2.

  When the alarm device 3 receives the intrusion information from the control device 2, the alarm device 3 issues an alarm with an indicator lamp, a buzzer, a voice, or the like. The type of alarm is not particularly limited, but it is preferable to combine the visual effect of the indicator lamp with the auditory effect of a buzzer or sound.

  Next, a specific application example of the designated range monitoring system 100 according to the present embodiment will be described with reference to FIGS. 2 to 7. FIG. 2 is a diagram illustrating an aerial work platform to which the specified range monitoring system according to the first embodiment is applied.

  The aerial work vehicle 10 is, for example, a vehicle for overhead work, and a turnable telescopic boom 11 is provided on a turntable. A bucket 12 for an operator to get on and work on is attached to the tip of the revolving telescopic boom 11. A photographing device 1 (camera) is attached to the bottom bottom surface of the bucket 12 so as to photograph the surroundings of the aerial work vehicle 10 from above. The photographing apparatus 1 is preferably a waterproof camera.

  A waterproof box 13 is attached to the top of the bucket 12. Inside the waterproof box 13 are stored a wireless router as a relay communication device of the network 4 in FIG. 1, and a battery for supplying power to the photographing apparatus 1 and the wireless router. The photographing apparatus 1 and the wireless router inside the box 13 are connected by a LAN cable.

  When the swinging telescopic boom 11 is extended, the working bucket 12 is raised, and the photographing apparatus 1 is raised as the bucket 12 is raised. And the imaging device 1 which rose has come to image | photograph the circumference | surroundings of the aerial work vehicle 10 from above.

  In addition, the control device 2 (tablet terminal) and the alarm device 3 can communicate with the wireless router inside the box 13, and the photographing device 1, the control device 2 (tablet terminal), and the alarm device 3 are connected to the wireless router. Connected via network.

  The control device 2 (tablet terminal) has a communication function, and has a display screen that displays image information transmitted from the photographing device 1. In addition, the designated range to be monitored can be arbitrarily set in the displayed shooting range based on the operation of the operator, and it can be detected that a person or another vehicle has entered the designated range. It has such an image processing function. It also has a function of transmitting intrusion information when an intrusion is detected.

  The alarm device 3 has a communication function, receives intrusion information from the control device 2, and issues an alarm with an indicator lamp and a buzzer. The type of alarm is not particularly limited, but in the case of using an indicator lamp, it is possible to notify the intrusion more reliably by switching the color at the time of alarm (changing the color during normal and intrusion). it can.

  Next, a method for using the designated range monitoring system 100 according to the first embodiment will be described. As a situation to be used, assume that a certain range of a sidewalk or a roadway is set as a designated range to be monitored and an intrusion of a person or a vehicle is monitored when overhead line construction is performed along the road.

  When the aerial work vehicle 10 arrives at the construction site and is ready for construction, an operator gets into the bucket 12 and extends the swivel telescopic boom 11 to raise the bucket 12 to a predetermined position. The photographing device 1 that has risen together with the bucket 12 photographs the surroundings of the aerial work vehicle 10 from above, and transmits the photographed image information to the control device 2 via the wireless router in the box 13.

  An operator on the ground (operator of the control device 2) confirms the video displayed on the display screen of the control device 2, operates the control device 2, and designates the designated range to be monitored within the photographing range of the photographing device 1. Set. The designated range is determined in consideration of the safety aspects of the construction. FIGS. 3 and 4 are diagrams illustrating a shooting range in which the shooting apparatus 1 takes a bird's-eye view from above the vehicle and a designated range by the control device 2.

  FIG. 3 shows a state in which a rectangular designated range 6 is set inside a circular shooting range 5. FIG. 4 shows a rectangular designated range 6 set inside a rectangular shooting range 7. Note that the shape of the shooting range and the specified range is not particularly limited, and can be any shape.

  Next, the alarm device 3 is arranged. The location of the alarm device 3 is not particularly limited, as long as it can notify the worker and the intruder of the danger, and is installed in the vicinity of the designated range 6 to be monitored. For example, FIG. 5 is a diagram showing a state in which the alarm device 3 is arranged in the designated range 6, but here it is arranged at a boundary portion of the designated range 6 set as a monitoring target. In this way, the entry of a person or another vehicle into the specified range can be notified more reliably. If there is a remote monitoring facility or the like other than the vicinity of the designated range 6 to be monitored, it may be installed at that location.

  Moreover, as shown in FIG. 6, the alarm device 3 having the alarm device 3 attached to the upper part of the safety cone 8 can be used to facilitate the arrangement of the alarm device 3 and improve the visibility. .

  When the safety cone 8 as shown in FIG. 6 is used, the alarm device 3 with an indicator lamp is arranged on the upper portion to switch the color at the time of alarm (change the color at the time of normal and intrusion), and for example, the safety cone 8 A voice type alarm device can be attached to the lower part of the screen to improve the recognizability by voice or melody.

  In addition to the method for setting the designated range based on the operation of the operator as described above, the method can be performed as follows. First, a plurality of setting indicators for setting the designated range are arranged within the imaging range. Then, the setting sign is recognized in the photographed image by the photographing apparatus 1, and the range of the recognized setting sign is designated as the designated range. For example, when the safety cone 8 is used as a setting indicator, the safety cone 8 is installed at the boundary portion of the specified range, and the difference in color and shape between the safety cone 8 and other portions in the photographed image by the photographing apparatus 1 is shown. It can be realized by performing image processing to be recognized. Further, a transmitter that can be recognized by the control device 2 may be attached to the safety cone 8. According to such a setting method, setting is easy because it is only necessary to place a setting mark.

  Further, as shown in FIGS. 9 and 10, the light emitting member 20 is attached to the upper surface of the safety cone 8 as a setting mark, and the setting means recognizes the blinking of the light emitting member 20 and sets the designated range. As a result, the setting mark can be recognized accurately in a short time. For example, when setting the specified range, ON / OFF of the light emitting member 20 may be controlled by wireless or the like. As the light emitting member 20, various types such as a light emitting method and a color can be used. For example, incandescent bulbs, LED bulbs, red and blue, etc. may be combined while considering cost and ease of recognition in image processing.

  As described above, the monitoring posture of the set designated range 6 is established. Next, a case where a person, a vehicle, or the like has entered the designated range 6 will be described. During monitoring, the image information of the video imaged by the imaging device 1 is always transmitted to the control device 2 via the wireless router in the box 13. When a person or a vehicle enters the designated range 6 to be monitored during monitoring, the control device 2 indicates that a person or another vehicle has entered the designated range 6 based on the image information sent from the imaging device 1. Is detected. Then, the control device 2 transmits intrusion information toward the alarm device 3.

  The intrusion information transmitted from the control device 2 is transmitted to the alarm device 3 via the wireless router in the box 13, and the alarm device 3 that has received the intrusion information issues an alarm using an indicator lamp, a buzzer, or the like. As described above, the danger can be notified to the worker and the intruder.

  The bucket 12 of the aerial work vehicle 10 may move depending on the progress of the work, but at that time, the photographing apparatus 1 attached to the bucket 12 also moves. In preparation for such a case, it is preferable to have a correction function that maintains the specified range 6 that has already been set. Referring to FIG. 7, first, as shown by the solid line in FIG. 7A, the monitoring target designation range 6 is set in the initial photographing range 5 by the photographing apparatus 1. Next, as the bucket 12 moves, it is assumed that the shooting range of the shooting device 1 has moved to the shooting range 5 ′ indicated by the broken line. Even in that case, as shown in FIG. By correcting the display of the designated range 6, the designated range 6 is maintained at the original position.

  Such a correction function can be realized by various methods. For example, the safety cone 8 is recognized as a setting mark, and the position information of the safety cone 8 in the shooting range 5 by the shooting device 1 is always acquired. When the bucket 12 moves, the position information of the safety cone 8 in the shooting range 5 is shifted. Therefore, when it is determined that the shift is greater than a predetermined value, the new shooting range 5 ′ is correct. The designated range 6 may be displayed. As another method, the display of the designated range 6 can be corrected by the amount of movement of the photographing apparatus 1 while collecting the absolute position information of the photographing apparatus 1 using GPS or the like.

  Moreover, it is preferable to provide the 2nd imaging device which image | photographs the working condition of the worker on a vehicle in addition to the imaging device 1. FIG. For example, the second image capturing device is installed inside the bucket 12 and transmits the captured image to the control device 2 via the wireless router. Thereby, in addition to the monitoring of the designated range, the worker on the ground can monitor the work status of the worker, and the safety can be taken into consideration.

  Next, another specific application example of the designated range monitoring system 100 according to the present embodiment will be described with reference to FIG. FIG. 8 is a diagram illustrating an aerial work vehicle to which the specified range monitoring system according to the second embodiment is applied.

As shown in FIG. 8, in the second embodiment, the photographing device 9 is attached to the upper part of the telescopic movement pole 14 mounted on the aerial work vehicle 10. The imaging device 9 is configured to take an image of the surroundings of the aerial work vehicle 10 from above as in the imaging device 1 in the first embodiment.

  A waterproof box 15 is attached to the top of the telescopic movement pole 14. The waterproof box 15 has the same configuration as the waterproof box 14 in the first embodiment.

  When the designated range monitoring system according to the second embodiment is used, when the aerial work vehicle 10 arrives at the construction site and is ready for construction, the telescopic moving pole 14 is extended to raise the photographing device 9. Subsequent operations are the same as those in the first embodiment.

  The pole to which the photographing device 9 is attached is preferably extendable and retractable. However, the present invention is not limited to this. For example, the pole may be laid down when not in use and may stand upright when in use. Moreover, even if it is not a pole-shaped thing, a shape will not be ask | required if it is a support body which can support an imaging device.

  Further, the support to which the photographing device 9 is attached is not necessarily provided on the vehicle from the beginning, and the support to which the photographing device is attached can be mounted on a vehicle that is not equipped. For example, it is possible to use a support attached with a photographing device mounted on a light truck bed.

  Moreover, it is preferable to comprise so that the support which attaches the imaging device 9 may be equipped with a general purpose fixing bracket so that it can attach to many types of vehicles. Further, for example, a tread plate portion may be formed in a lower portion of the support, and the support may be fixed by stepping on the tread plate portion with a vehicle tire or the like.

  In the designated range monitoring system according to the present embodiment, the photographing device 1 photographs the surroundings of the vehicle 10 from above, and setting means provided in the photographing device 1 or the control device 2 is within the photographing range 5 by the photographing device 1. Since the designated range 6 to be monitored is set to the monitoring range, the monitoring range can be freely set according to the use situation. In addition, since the detection means provided in the photographing device 1 or the control device 2 detects that a person or another vehicle has entered the designated range 6 and transmits intrusion information, the power line is used to detect the intrusion. In addition, there is no need to install an ultrasonic or infrared generator, an infrared camera, or the like, and a simple system configuration can be realized at low cost. And since the alarm device 3 receives the intrusion information and gives an alarm, the intrusion of a person or another vehicle into the designated range 6 can be surely notified.

  In addition, by connecting the photographing device 1, the control device 2, and the alarm device 3 to a network, each device can be freely arranged according to the use situation.

  Further, by attaching the photographing device 1 to the working bucket 12 mounted on the vehicle 10, the photographing device 1 can be raised as the working bucket 12 rises. It is possible to take a picture of the surroundings from above.

  Further, by attaching the photographing device 9 to the support 14 that can be mounted on the vehicle 10, even if the vehicle 10 is not equipped with the photographing device 9, the support 14 with the photographing device 9 is mounted. The system can be used.

  Further, by making the support 14 that can be mounted on the vehicle 10 extendable and retractable, the photographing device 9 can be raised in accordance with the elongation of the support 14, and the periphery of the vehicle 10 is moved upward by the raised photographing device 9. You can shoot from a bird's-eye view.

  Further, the setting means sets the designated range 6 based on the operation of the operator, so that the operator can set the designated range 6 at an arbitrary position.

  In addition, the setting unit recognizes the setting mark placed in the photographing range 5 and sets the designated range 6, so that the designated range 6 can be easily set only by placing the setting sign.

  In addition, the setting means recognizes the color of the light emitting member 20 attached to the setting mark arranged in the photographing range 5 and sets the designated range 6 so that the sign can be recognized accurately in a short time. it can.

  Further, even if the photographing apparatus 1 moves with the movement of the work bucket 12, the set designation range 6 is maintained so that the monitoring target can be designated even if the work progresses and the bucket 12 moves. The range 6 can be prevented from changing.

  In addition, by arranging the alarm device 3 at the boundary portion of the designated range 6, it is possible to more reliably notify the invasion of a person or another vehicle into the designated range 6.

  Further, when the warning device 3 is an indicator lamp, by switching the color at the time of warning, it is possible to more reliably notify the invasion of a person or another vehicle into the designated range 6.

  When the vehicle 10 is a working vehicle, the worker's work status is monitored in addition to the monitoring of the designated range 6 by photographing the worker's work situation on the vehicle with the second photographing device. It is possible to consider safety.

  As described above, according to the designated range monitoring system according to the present embodiment, the designated range monitoring system for monitoring the intrusion of a person or another vehicle into the designated range around the vehicle is realized at a low cost with a simple system configuration. In addition, the monitoring range can be set freely. Further, when setting the designated range using the setting mark, the processing time can be shortened and the accuracy can be improved.

  Although the specified range monitoring system according to the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various other modifications are possible.

  For example, regarding the vehicle, in the above-described embodiment, the vehicle is an aerial work vehicle for overhead construction, but may be applied to a construction / civil engineering vehicle (excavator car, etc.), a truck for transportation, a passenger car, and the like. Is possible.

  Regarding the network, in the above-described embodiment, the wireless router, which is a relay communication device, is installed in a waterproof box in the vicinity of the photographing apparatus, but the installation location of the relay communication device is not limited. In addition, each device and the relay communication device may be configured by either wired or wireless connection. Further, the relay communication device may be integrated with any of the devices.

  In addition, regarding the control device, the tablet terminal is used in the above-described embodiment. However, for example, a personal computer installed in a vehicle or a personal computer installed in a remote monitoring facility may be used. However, a tablet terminal is preferable from the viewpoint of operability on site.

  In addition, the destination to which the intrusion information from the control device is transmitted may be transmitted to a remote management department such as a head office or a sales office of a construction company other than the alarm device.

  Further, position information held by the control device (for example, using a built-in GPS or using a position information providing service for a line to be used) may be added to image information from the photographing apparatus. Then, for example, when performing cooperative work at a plurality of sites, such as overhead line construction in a neighboring area, the position information held by the control device arranged at each site may be used for position confirmation at the time of cooperative work.

  In addition, the specified range monitoring system according to the present embodiment monitors the specified range around the vehicle at the construction site. However, in the present invention, it is not always necessary to limit the vehicle periphery to the monitoring target. It is applicable to the designated range in the entire construction site including. Therefore, instead of mounting the photographic device on the vehicle or mounting the support attached to the photographic device on the vehicle, the photographic device is installed on a stand with a height at the construction site, and within the shooting range of the entire construction site. A specified range can also be set.
