Description

  The present invention relates to control of lighting in a mine in tunnel construction.

  In general, in tunnel construction, a plurality of lights are provided from the tunnel pit to the excavation work section at the tip of the tunnel. As the tunnel construction progresses, the distance from the tunnel well to the excavation section at the tip of the tunnel becomes longer, and the number of lights provided in the tunnel also increases. These lights are always turned on during the tunnel construction work in consideration of workability and safety in the tunnel construction.

  As a result, since a large number of lights are always turned on in tunnel construction, the amount of power consumed by the lights increases, and energy consumption in tunnel construction increases.

  On the other hand, in recent years, energy conservation has been required in various fields of society due to concerns about global warming, and energy conservation in construction work such as tunnel construction is also required. As one of energy saving methods, there is one that reduces the power consumption of the ventilation system while maintaining the working environment in the tunnel by controlling the ventilation system in the tunnel (see Patent Document 1).

The lighting state can be maintained.

  According to this aspect, the control means can maintain the lighting state in the excavation work section of the tunnel regardless of the position information of the moving body. Therefore, even if the moving body frequently moves in the tunnel mine, excavation of the tunnel is possible. In the work section, since the lighting state necessary for excavation work is maintained, the workability of tunnel construction can be improved.

  A lighting control system according to a fifth aspect of the present invention is the lighting control system according to any one of the first to fourth aspects, wherein the information terminal transmits identification information of the mobile body, and the receiving unit receives the identification information. The control means is characterized in that the lighting of the lighting or the amount of light of the lighting can be reduced in the plurality of sections based on the identification information of the moving body.

Is possible.

  According to this aspect, the control means can turn off the illumination of the excavation work section of the tunnel when the tunnel mine becomes unmanned. In other words, when the tunnel mine is unmanned, the excavation work in the excavation work section is also temporarily suspended, so there is no need to turn on the light in the excavation work section. By turning off the illumination, the power consumption of the illumination can be reduced and energy saving can be achieved.

  The lighting control system according to an eighth aspect of the present invention includes, in any one of the first to seventh aspects, a ventilation device that ventilates a tunnel tunnel, and at least one predetermined movement in the ventilation device and the moving body.

Or the amount of illumination light can be reduced. For example, when a predetermined moving body, that is, a rock drill or a concrete sprayer is operating in a tunnel excavation work section, most of the work in the tunnel is concentrated in the excavation work section. The frequency of work is reduced. Therefore, since it is not necessary to turn on the illumination of these sections, it is possible to adjust the brightness by reducing the amount of illumination of these sections, so that the power consumption of the illumination can be reduced, Energy saving can be achieved.

  Also, it is possible to determine the amount of power used from the operation information of the ventilator, and to control the lighting of sections other than the excavation work section when the used power amount of the ventilator exceeds a predetermined power amount. it can. Specifically, when the power consumption of the ventilator exceeds a predetermined amount of energy, a large amount of dust is generated in the excavation work section by carrying out excavated earth and sand and rocks. Since it is determined, it is possible to perform control to turn on the illumination in sections other than the excavation work section. Thereby, the work efficiency in the tunnel mine can be improved and the safety of the work can be improved.

  Also, if the power consumption of the ventilator is lower than the specified power amount, it is determined that work other than carrying out the excavated earth and sand or rock is being performed in the excavation work section, and most of the work is excavation work. Since it concentrates on a section, the control which reduces the light quantity of illumination can be performed in sections other than an excavation work section. As a result, the power consumption of illumination can be reduced and energy saving can be achieved.

  In the present specification, “operation information” is information obtained from the power consumption of the ventilator and a predetermined moving body, and includes information on the magnitude of the power consumption.

  The lighting control system according to a ninth aspect of the present invention is the lighting control system according to the eighth aspect, wherein when the control means detects that all of the predetermined moving bodies are in an inoperative state, It is possible to turn on the illumination or reduce the amount of the illumination light.

  According to this aspect, when the control means detects that all of the predetermined moving bodies are not in operation, it is possible to turn on the illumination in a plurality of sections. For example, when a predetermined moving body, that is, a rock drill or a concrete sprayer, is not in operation in a tunnel excavation work section, work is carried out of the earth and rock excavated from the excavation work section out of the tunnel with a dump or the like. . At this time, a large amount of dust is generated in the excavation work section due to carrying out sediment and the like, and the power consumption of the ventilator exceeds the predetermined power amount. Therefore, since the control means can determine that work such as earth and sand is being carried out in the tunnel mine, vehicles that frequently go back and forth between the tunnel mine and the inside of the tunnel by turning on the lighting in multiple sections It is possible to improve the safety of the work and improve the work efficiency in the tunnel.

<<<< first embodiment >>
Illumination control of the illumination control system 12 will be described with reference to FIGS. 2, 3 (A), and 3 (B). In FIG. 2, for example, when the worker 24 is located in the fifth section from the wellhead of the tunnel 10, the information terminal 16 transmits the position information of the worker 24 to the receiving unit 18 provided in the fifth section. .

  The receiving unit 18 provided in the fifth section receives the position information of the worker 24 from the information terminal 16 and transmits the position information to the control computer 20. The control computer 20 turns on the illumination 14 in the fifth section based on the received position information of the worker 24. In this embodiment, the excavation work section 11, which is the nth section, performs excavation work. Therefore, the control computer 20 illuminates the illumination 14 regardless of the movement of the moving body 22 while working in the excavation work section 11. Is controlled to be in a lighting state.

  In the present embodiment, the control computer 20 is in a state in which the light amount of the illumination 14 in the fourth section and the sixth section adjacent to the fifth section in which the worker 24 is located is reduced, that is, in a state in which the brightness is adjusted. It is turned on. Thereby, when the worker 24 moves to the fourth section or the sixth section adjacent to each other, the adjustment time for the light amount of the illumination 14 necessary for the worker 24 to move or work can be shortened. As a result, the workability and safety in the tunnel 10 of the worker 24 can be improved.

  Further, in this embodiment, the control computer 20 is a section of the section in which the moving body 22 is detected among the illuminations 14 provided in a plurality of sections divided from the tunnel entrance to the excavation work section 11 of the tunnel 10. Illumination can be turned on and the amount of illumination light in other sections can be reduced. As a result, it is possible to brightly illuminate sections necessary for work in the moving body 22 and the tunnel 10, and to adjust the brightness of the illumination by reducing the light quantity of the illumination 14 in sections where the illumination 14 is not required to be turned on. Therefore, the power consumption of the lighting 14 in tunnel construction can be reduced, and energy saving can be achieved.

  Next, with reference to FIG. 3A and FIG. 3B, each of the cases where the worker 24 as an example of the moving body 22 moves from the fifth section in FIG. The control of the illumination 14 in the section will be described.

  As shown in FIG. 3A, the worker 24 is in a state located in the fifth section from the wellhead Y <b> 1 of the tunnel 10. From this state, the movement starts to the wellhead Y1 of the tunnel 10 in the -Y direction. The information terminal 16 carried by the worker 24 when the worker 24 shown in FIG. 3B moves from the state where the worker 24 shown in FIG. 3A is located in the fifth section to the fourth section. Transmits the position information of the worker 24 to the receiving unit 18 in the fourth section and the receiving unit 18 in the fifth section.

  Specifically, when the worker 24 moves from the fifth section to the fourth section, the reception unit 18 of the fifth section has a reception strength of the position information transmitted from the information terminal 16 of the worker 24. become weak. On the other hand, in the receiving unit 18 in the fourth section which is the movement direction of the worker 24, the reception strength of the position information transmitted from the information terminal 16 of the worker 24 is increased.

  Therefore, the control computer 20 can detect the moving direction of the worker 24 based on the reception intensity of the position information from the information terminal 16 of the receiving unit 18 in the fourth section and the receiving unit 18 in the fifth section. As a result, the control computer 20 can turn on the illumination 14 in the fourth section, which is the movement direction of the worker 24, or can completely turn on the illumination 14 from a state in which the light amount of the illumination 14 is reduced.

  On the other hand, the control computer 20 reduces the light amount of the illumination 14 in the fifth section where the worker 24 has finished moving. When the control computer 20 moves from the fourth section to the third section, from the third section to the second section, from the second section to the first section, the third section The lighting 14, the lighting 14 in the second section, and the lighting 14 in the first section are turned on in this order to reduce the amount of light of the lighting 14 in the section through which the worker 24 has passed.

  Therefore, the control computer 20 turns on the illumination 14 in the section adjacent to at least the section where the moving body 22 is located in the moving direction of the moving body 22 based on the position information of the moving body 22, and the moving body 22 has passed. The light quantity of the partition illumination 14 is reduced. In other words, since the moving direction of the moving body 22 is brightly illuminated, the moving body 22 can be moved safely, and the brightness of the lighting 14 can be adjusted by reducing the light amount of the lighting 14 in the section through which the moving body 22 has passed. Can be reduced, and energy saving can be achieved.

<<< First Modification in First Embodiment >>>
In addition, as a first modification of the control of the illumination 14 accompanying the movement of the moving body 22 shown in FIGS. 3A and 3B, the control examples shown in FIGS. 4A and 4B are shown. Indicates. In this control example, the control computer 20 receives the movement of the moving body 22 (the worker 24 in FIG. 4A and the vehicle 26 in FIG. 4B) received by the receiving unit 18 provided in each section. When the detection is performed based on the position information, the lights 14 in all the sections in the movement direction (the fourth section from the first section in FIG. 4A) are turned on.

In particular, as shown in FIG. 4B, when the moving body 22 is a vehicle 26, the moving speed is faster than the moving speed of the worker 24. Therefore, in the control for lighting only the adjacent section, It is also conceivable that switching from the state in which the light amount of the illumination 14 in the section adjacent to the moving speed is reduced to the lighting state is not in time. In this embodiment, when the control computer 20 identifies that the moving body 22 is the vehicle 26 based on the identification information from the information terminal 16, the lighting of all sections in the moving direction of the moving body 22 is turned on in advance. Therefore, it is possible to prevent the lighting of the lighting 14 from being in time for the movement of the vehicle 26 (the moving body 22) in the section in the movement direction, and the safety is improved in the movement of the vehicle 26 moving at a high speed in the tunnel 10.
Energy can be achieved.

  That is, the control computer 20 can turn on the illumination 14 or reduce the amount of light of the illumination 14 in a plurality of sections based on the identification information of the moving body 22, so that the moving body 22 is identified as the worker 24, for example. In such a case, the lighting 14 in the section where the worker 24 is brightened or the light amount of the lighting 14 is decreased in the section where the worker 24 is not present, and the section where the lighting 14 is not necessary and the section where the lighting 14 is not necessary. The brightness of the illumination 14 can be adjusted by turning on the illumination 14 or reducing the amount of light of the illumination 14, respectively. As a result, the power consumption of the illumination 14 can be reduced and energy saving can be achieved.

<<< Second Modification of First Embodiment >>>
With reference to FIG. 5 (A) and FIG. 5 (B), the 2nd modification in control of the illumination 14 in the tunnel 10 is demonstrated further. In the construction work of the tunnel 10, there is a worker 24 who supports the construction work of the tunnel 10 in addition to the worker 24 directly engaged in the construction in the tunnel 10. As an example of the worker 24 that supports the construction work, there is a contact person 30 that transmits documents and instructions between a construction work office provided near the outside of the tunnel 10 and a work site in the tunnel 10. The contact person 30 is also an example of the moving body 22.

  The contact person 30 may reciprocate several times between the work site in the tunnel 10 mine and the construction work office outside the tunnel 10 during the day. Therefore, if the control is performed to turn on the illumination 14 of each section or reduce the light quantity of the illumination 14 every time the contact person 30 moves within the tunnel of the tunnel 10, the adjustment of the light quantity of the illumination 14 of each section is repeated every time the round trip is performed. This may increase the power consumption of the illumination 14.

  As an example, as shown in FIG. 5A, the control computer 20 controls the illumination 14 in a state where the amount of light is reduced in a plurality of sections in the tunnel 10. In this state, when the control computer 20 receives the position information and identification information of the contact person 30 heading into the tunnel 10 at the tunnel well Y1 through the receiving unit 18, the control computer 20 lights in the moving direction of the contact person 30. The lighting state of the illumination 14 is maintained in a state where the amount of light 14 is reduced, that is, in a state where the brightness of the illumination 14 is adjusted. That is, the control computer 20 maintains a light amount, that is, brightness, which does not hinder the movement of the contact person 30 in the tunnel 10. And it maintains in the state which reduced the light quantity of the illumination 14 of the area which the contact person 30 finished moving toward the inside of the tunnel from the wellhead Y1 of the tunnel 10. FIG.

  Next, when the contact person 30 finishes the work in the tunnel 10 and moves from the inside of the tunnel 10 toward the outside of the tunnel 10, the control computer 20 similarly controls the lighting 14 in the section where the contact person 30 has finished moving. Keep the amount of light reduced.

  Although not shown, the same applies to the case of the vehicle 26 for communication in which the moving body 22 frequently reciprocates between the outside of the tunnel 10 and the inside of the tunnel. Further, in a state where the illumination 14 in the tunnel 10 is completely lit, the control computer 20 performs control so as to maintain the illumination 14 in a completely lit state.

  Next, although not shown, when the moving body 22 is a large vehicle 26 such as a dump truck for carrying out earth and sand, the control computer 20 moves from the pit Y1 of the tunnel 10 toward the pit of the tunnel 10 at the pit Y1 of the tunnel 10. When the identification information of the vehicle 26 is detected, the lighting 14 of all sections is completely turned on along the moving direction. And the control computer 20 reduces the light quantity of the illumination 14 of the area where the large sized vehicle 26 passed.

  Then, when the large vehicle 26 such as a dump truck finishes the work in the tunnel 10 and moves from the inside of the tunnel 10 toward the outside of the tunnel, the lighting 14 of the entire section along the moving direction of the large vehicle 26. Turn on completely. Then, the control computer 20 performs control to adjust the state in which the light amount of the illumination 14 in the section where the vehicle 26 has finished moving, that is, the brightness of the illumination 14 is adjusted.

  Moreover, when the mobile body 22 frequently reciprocates between the outside of the tunnel 10 and the inside of the tunnel, the control computer 20 performs control so that the lighting state of the illumination 14 in the excavation work section 11 which is the nth section is maintained.

  When the moving body 22 frequently reciprocates between the outside of the tunnel 10 and the inside of the tunnel 10, the control computer 20 maintains the lighting state of the illumination 14 in the excavation work section 11 of the tunnel 10 regardless of the position information of the moving body 22. Even if the moving body 22 frequently moves in the tunnel 10, the lighting state of the lighting 14 necessary for the excavation work is maintained in the tunnel excavation work section 11, so that the workability of the tunnel construction can be improved. it can.

<<< Third Modification of First Embodiment >>>
With reference to FIG. 6, the 3rd modification in control of the illumination 14 in the tunnel 10 is demonstrated. Also in this modified example, the control computer 20 maintains the lighting state of the illumination 14 in the excavation work section 11 which is the nth section even if the moving body 22 moves between the first and the (n-1) th section. Control to do.

  On the other hand, it is controlled that the worker 24 has left the entire section of the tunnel 10 and that the tunnel 10 has become unmanned based on the position information and identification information of the information terminal 16 carried by the worker 24. When the computer 20 detects, the control computer 20 turns off the lights 14 in all sections including the excavation work section 11. Note that the control computer 20 may control to adjust the brightness of the illumination 14 by reducing the light amount of the illumination 14 in all sections instead of turning off the illumination 14 in all sections.

  That is, when the inside of the tunnel 10 is unmanned based on the identification information of the moving body 22, the control computer 20 turns off the illumination 14 in a plurality of sections. That is, since the control computer 20 turns off the illumination 14 in a plurality of sections in the tunnel 10 tunnel in the state where it is not necessary to turn on the illumination 14 in the tunnel 10 tunnel, the power consumption of the illumination 14 can be reduced. , Energy saving can be achieved.

  In addition, when the tunnel 10 is in an unmanned state, the excavation work in the excavation work section 11 is also temporarily interrupted, so it is not necessary to turn on the illumination 14 in the excavation work section 11. . Therefore, by turning off the illumination 14 in the excavation work section 11, the power consumption of the illumination can be reduced and energy saving can be achieved.

<<< Fourth Modification of the First Embodiment >>>
Next, with reference to FIGS. 7A to 9, a fourth modification example in the control of the illumination 14 in the tunnel 10 will be described. In this modified example, the control computer 20 turns on the lighting 14 from the first section of the tunnel 10 to the (n-1) -th section according to the work content in the excavation work section 11, which is the n-th section, or the lighting 14 Control to reduce the amount of light.

  This will be specifically described below. The work process in the excavation work section 11 includes a rock drilling / charging / blasting process as a first process, a drilling / slip-out process as a second process, and a steel support construction as a third process. There is a process, there is a shotcrete construction process as the fourth process, and there is a rock bolt placing process as the fifth process.

  During the work process in the excavation work section 11, many work machines 28 operate in the excavation work section 11. In particular, the operation information of the hydraulic rock drill 32 and the concrete sprayer 34 set as the “predetermined moving body” is transmitted from the measuring device 19 provided to each to the receiving unit 18 provided in the excavation work section 11. And received by the control computer 20 via the receiving unit 18. In this modified example, the working machines 28 include, for example, a hydraulic rock drill 32, a concrete sprayer 34, a backhoe 36, a dump truck 38, and the like. In the present embodiment, the hydraulic rock drill 32 and the concrete sprayer 34 are set as “predetermined moving bodies”, but the working machines included in a number of work machines 28 are set as “predetermined moving bodies”. Also good.

  As shown in FIG. 7A, the hydraulic rock drill 32 is operated in the excavation work section 11 in the rock drilling / charging / blasting process which is the first process. Therefore, the control computer 20 receives the operation information of the hydraulic rock drill 32 transmitted from the measuring device 19 via the receiving unit 18. Further, the hydraulic rock drill 32 excavates an excavation hole for charging explosive or explosive at the tip (face) of the excavation work section 11. After that, the explosive hole is charged with explosive or explosive, blasted, and the tip (face) is cut. In this step, the control computer 20 reduces the light quantity of the illumination 14 in a plurality of sections from the first section to the (n-1) th section.

  Next, as shown in FIG. 7 (B), the backhoe 36 and the dump truck 38 are operated in the projecting process as the second process. Specifically, earth and sand and rocks cut at the tip (face) of the excavation work section 11 are loaded onto the dump truck 38 by the backhoe 36 and are carried out of the excavation work section 11 to the outside of the tunnel 10. Thereby, the dump truck 38 reciprocates between the excavation work section 11 and the outside of the tunnel 10 a plurality of times.

  In the second step, the hydraulic rock drill 32 and the concrete sprayer 34, which are the predetermined moving body 22, are not operating, and the operation information of the hydraulic rock drill 32 and the concrete sprayer 34 is not transmitted. . On the other hand, a large amount of dust is generated in the excavation work section by carrying out earth and sand from the excavation work section 11. This dust is detected by an environmental sensor (not shown) provided in the ventilator 44, and the ventilator 44 adjusts the rotational speed of the fan 46 to increase the amount of air fed into the excavation work section 11. As a result, the power consumption of the ventilator 44 increases. This increase in power consumption is transmitted from the measuring device 19 to the control computer 20 via the receiving unit 18 as operation information of the ventilation device 44.

  Therefore, since the control computer 20 can determine that the work in the tunnel mine is the second step based on the operation information of the hydraulic rock drill 32 and the concrete sprayer 34 and the operation information of the ventilation device 44, from the first section. Illumination 14 in a plurality of sections up to the (n-1) th section is turned on.

  Next, as shown in FIG. 8A, in the steel support construction process, which is the third process, the hydraulic rock drill 32 is operated again, and the operation information of the hydraulic rock drill 32 is obtained from the measuring device 19. Transmitted to and received by the control computer 20 via the receiving unit 18. In this step, the steel support 40 is installed at the tip (face) of the excavation work section 11 using the hydraulic rock drill 32.

  Also in the third step, the work in the tunnel of the tunnel 10 concentrates on the excavation work section 11, so the control computer 20 reduces the light amount of the illumination 14 in the sections other than the excavation work section 11 in the third process.

  Next, as shown in FIG. 8B, in the shotcrete construction process that is the fourth process, the concrete sprayer 34 operates in the excavation work section 11. The operation information of the concrete sprayer 34 is transmitted from the measuring device 19 provided in the concrete sprayer 34 and received by the control computer 20 via the receiving unit 18. The concrete sprayer 34 sprays concrete onto the wall surface at the tip (face) of the excavation work section 11 to increase the strength of the tip (face) and stabilize the tip (face).

  Even in the fourth step, the work in the tunnel of the tunnel 10 concentrates on the excavation work section 11, so the control computer 20 reduces the light amount of the illumination 14 in the sections other than the excavation work section 11 in the fourth process.

  Next, as shown in FIG. 9, in the rock bolt placing process as the fifth process, the hydraulic rock drill 32 is operated, and the operation information of the hydraulic rock drill 32 is transmitted from the measuring device 19, and the control computer 20. Are received via the receiving unit 18. In this step, the rock bolt 42 is driven into the soil from the wall surface of the tunnel 10 toward the outer periphery using the hydraulic rock drill 32.

  Even in the fifth step, the work in the tunnel of the tunnel 10 is concentrated in the excavation work section 11, so the control computer 20 reduces the light amount of the illumination 14 in the sections other than the excavation work section 11 in the fifth process.

  Further, in this modified example, the control computer 20 detects the worker 24 and the contact person 30 in a section other than the excavation work section 11 in the first process, the third process to the fifth process, or the worker 24, When the movement of the contact person 30 and the vehicle 26 is detected, based on the position information and identification information of the moving body 22, control for turning on the illumination 14 already described is performed.

  In this modified example, the control computer 20 operates the ventilation device 44 for ventilating the tunnel 10 in the excavation work section 11 of the tunnel 10 and the hydraulic rock drill 32 and the concrete sprayer 34 as at least one predetermined moving body. By analyzing the information, it is possible to turn on the illumination 14 in the sections other than the excavation work section 11 of the tunnel 10 or reduce the light amount of the illumination 14. For example, when a predetermined moving body, that is, a hydraulic rock drill 32 or a concrete sprayer 34 is operating in the excavation work section 11 of the tunnel 10, most of the work in the tunnel 10 is concentrated in the excavation work section 11. The frequency of work in sections other than the excavation work section 11 decreases. Therefore, since it is not necessary to turn on the illuminations 14 in these sections, it is possible to adjust the brightness by reducing the light amount of the illuminations 14 in these sections, so that the power consumption of the illumination 14 is reduced. Can save energy.

  Moreover, the magnitude | size of electric power consumption is judged from the operating information of the ventilator 44, and when the electric energy consumption of the ventilator 44 exceeds predetermined electric energy, the illumination 14 of sections other than the excavation work area 11 is turned on. It can be performed. Specifically, when the amount of power used by the ventilator 44 exceeds a predetermined amount of power, a large amount of dust is generated in the excavation work section 11 by carrying out the excavated earth and sand and rocks. Since the state is determined, it is possible to perform control to turn on the illumination 14 in sections other than the excavation work section 11. Thereby, the work efficiency in the tunnel 10 mine can be improved and the safety of the work can be improved.

  Further, when the power consumption of the ventilator 44 is less than the predetermined power amount, it is determined that work other than the excavation work of the earth and sand excavated in the excavation work section 11 is being performed, and most of the work is performed. Since it concentrates on the excavation work section 11, it is possible to perform control to reduce the light amount of the illumination 14 in sections other than the excavation work section 11. As a result, the power consumption of the illumination 14 can be reduced and energy saving can be achieved.

  In addition, when the control computer 20 detects that both the hydraulic rock drill 32 and the concrete sprayer 34, which are predetermined moving bodies, are not operating, the lighting 14 can be turned on in a plurality of sections. It is. For example, when a predetermined moving body, that is, the hydraulic rock drill 32 or the concrete sprayer 34 is not in operation in the excavation work section 11 of the tunnel 10, the earth and sand excavated from the excavation work section 11 are dumped out of the tunnel. The work is carried out. At this time, a large amount of dust is generated in the excavation work section 11 due to carrying out sediment and the like, and the power consumption of the ventilator 44 exceeds the predetermined power amount. Therefore, since the control computer 20 can determine that earth and sand etc. are being carried out in the tunnel 10 mine, the lighting is turned on in a plurality of sections to frequently move between the outside of the tunnel 10 and the inside of the mine. As a result, it is possible to improve the safety of the operation of the vehicle and the like and improve the working efficiency in the tunnel 10.

  In this modified example, the lighting 14 in the sections other than the excavation work section 11 is controlled based on the operation information of the hydraulic rock drill 32, the concrete sprayer 34, and the ventilation device 44, which are predetermined moving bodies. Instead of this configuration, the lighting 14 in the sections other than the excavation work section 11 is controlled only by the operation information of the hydraulic rock drill 32 and the concrete sprayer 34, which are predetermined moving bodies, or only the operation information of the ventilation device 44. May be.

  Summarizing the above description, the lighting control system 12 in the tunnel in the tunnel construction in this embodiment includes the illumination 14 provided in a plurality of sections divided from the wellhead Y1 of the tunnel 10 toward the excavation work section 11 of the tunnel 10, An information terminal 16 that has a movable body 22 that is movable in a plurality of sections, transmits position information of the mobile body 22, a reception unit 18 that receives position information from the information terminal 16, and the reception unit 18 And a control computer 20 that controls the illumination 14 based on the positional information of the moving body 22 received.

When the moving body 22 moves over a plurality of sections, the control computer 20 illuminates the section 14 adjacent to at least the section where the moving body 22 is located in the moving direction of the moving body 22 based on the position information of the moving body 22. Is turned on, and the amount of light of the illumination 14 in the section through which the moving body 22 has passed can be reduced.

  The control computer 20 can turn on the lights 14 in all sections in the moving direction of the moving body 22. The control computer 20 can maintain the lighting state of the illumination 14 in the excavation work section 11 of the tunnel 10 regardless of the position information of the moving body 22.

  The information terminal 16 transmits the identification information of the moving body 22, and the receiving unit 18 receives the identification information. The control computer 20 can turn on the illumination 14 or reduce the light amount of the illumination 14 in a plurality of sections based on the identification information of the moving body 22.

The ventilation device 44 and the hydraulic rock drill 32 and the concrete sprayer 34, which are the moving bodies, are provided with a measuring device 19 that measures the amount of power used. The measuring device 19 transmits operating information of the ventilation device 44, the hydraulic rock drill 32, and the concrete sprayer 34, and the receiving unit 18 receives the operating information. The control computer 20 analyzes the operation information of the ventilation device 44 or the hydraulic rock drill 32 and the concrete sprayer 34 in the excavation work section 11 of the tunnel 10 to turn on the illumination 14 in the sections other than the excavation work section 11 of the tunnel 10. Alternatively, it is possible to reduce the amount of light of the illumination 14. When the control computer 20 detects that all of the hydraulic rock drill 32 and the concrete sprayer 34 are not operating, it is possible to turn on the lighting 14 or reduce the light amount of the lighting 14 in a plurality of sections.
