Description

The present invention relates to a construction site guidance system and a construction site guidance method.

In tunnel construction, the distance from the pit mouth to the face is extended by cutting from the pit mouth side. As the tunnel construction nears completion, the distance from the pit mouth to the face becomes longer, so it is necessary to travel by car. Here, there are various rules in the mine. For example, when traveling in a mine by vehicle, there are restrictions on driving speed and sounding the horn twice around the center. Observing such rules is very important in avoiding serious accidents.
Patent Document 1 describes a device that displays a warning on a map on a display screen of a car navigation terminal when a vehicle approaches a dangerous area.

JP 2002-181564 A

However, even if the car navigation terminal described in Patent Document 1 is used for underground construction work such as tunnel construction or construction work in narrow spaces, the car navigation terminal generally uses a GPS (global positioning system) to determine the position of the vehicle. Since it is difficult to receive GPS radio waves for measurement, the position of the vehicle cannot be measured and warning cannot be issued. In addition, even if the vehicle's position is estimated using a gyro sensor, acceleration sensor, etc., the tunnel under construction is usually not registered in the map data of the car navigation terminal, so a warning based on the map data will be issued. I can't. As described above, at construction sites, there may be areas where GPS cannot be used or locations that are not on the map, so there is a problem that information cannot always be stably distributed.

A construction site guidance system according to an embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is a schematic functional configuration diagram explaining the concept of a construction site guidance system 1 according to one embodiment of the present invention. The construction site guidance system 1 includes a construction site guidance server 10 , a beacon device 20 , and a terminal device 30 that can be mounted on a vehicle moving through the tunnel 2 . The construction site guidance system 1 can also be configured to include a terminal device 30A.
The tunnel 2 is a tunnel in which construction such as excavation and concrete placement is being performed, and the construction proceeds from the pithead 2a toward the face 2b. In this embodiment, the tunnel 2 will be described as being excavated, but it may be repaired or inspected after the tunnel 2 is completed. Tunnel 2 may be a mountain tunnel, a subway tunnel, a shield tunnel, or the like.
The vehicle 3 is used by a worker who constructs the tunnel 2, and is used to move from the outside of the construction site to the pithead 2a and to move between the pithead 2a and the face 2b.

A plurality of beacon devices 20 are installed along the longitudinal direction of the tunnel 2 where construction of the tunnel 2 is performed, and each transmits beacon identification information for identifying itself. The range (transmission intensity, etc.) for transmitting the beacon identification information is set so as to correspond to the transmission target area for transmitting the guidance information. When the beacon device 20 wants to set the transmission target region larger than the range in which the beacon identification information can be transmitted, a plurality of beacon devices 20 may be provided to cover the transmission target region.

Here, as an example of the progress of the construction of the tunnel 2, a case where excavation is performed from the pithead 2a to the face 2b to about 1500 m will be described as an example. 20b is installed at a position about 300 m from the pit 2a to the face 2b side, the beacon device 20c is installed at a position of about 700 m from the pit 2a to the face 2b side, and the beacon device 20d is about 1000 m from the pit 2a to the face 2b side. placed in position. The place where the beacon device 20 is installed can be arbitrarily installed at one place or a plurality of places in the tunnel 2 with respect to places where guidance information may be transmitted.

The beacon device 20 is installed with respect to the transmission target area|region, when the transmission target area|region of guidance information is newly set by construction in a construction site being performed. For example, when the construction site is a construction site where tunnel construction is performed, the beacon device 20 is newly excavated in the longitudinal direction from the tunnel opening 2a due to the tunnel construction (when the excavation progresses), the new excavation is performed. The selected location can become a new communication target area. Moreover, it can be a place outside the communicable area of the existing beacon device 20 . Therefore, the beacon device 20 is newly installed in the place (the inside of a tunnel etc.) which became the new communication object area in this way. In this way, the beacon device 20 can be additionally installed according to the progress of construction of the tunnel 2 . The construction site may be an underground space or a facility (dam, parking lot, etc.) provided in a mountainous area other than a tunnel. Such places are places where the radio wave environment for general wireless communication is not stable, or where wireless communication cannot be established (radio waves do not reach) between the base station and the terminal device for wireless communication. is often

The beacon device 20 can be installed, for example, on a wall surface or a ceiling on the inner peripheral side of the tunnel 2, or may be installed on equipment (shoring) used for construction of the tunnel 2, or the like.
Hereinafter, beacon devices 20a, 20b, 20c, and 20d are simply referred to as beacon devices 20 unless otherwise identified.

Further, when the beacon identification information is received from the terminal device 30, the communication unit 11 reads the guidance information corresponding to the beacon identification information from the storage unit 12 and transmits it to the terminal device 30 that transmitted the beacon identification information. The communication unit 11 can also transmit the guidance data stored in the guidance information storage unit 121 to the terminal device 30 when the construction site guidance server 10 and the terminal device 30 are in a communicable state.
The construction site guide server 10 can be realized by a combination of a CPU (Central Processing Unit), a communication circuit, an antenna device, a storage device, and the like.
The storage unit 12 stores various information. For example, the storage unit 12 has a guidance information storage unit 121 and a guidance log storage unit 122 . The guidance information storage unit 121 stores guidance information and beacon identification information as guidance data. Guidance information should just be the guidance information according to the position in which the beacon device 20 was installed, or the area|region which can receive the beacon identification information of the beacon device 20. FIG. Further, the guidance information may include language-specific data expressing one message in different languages. Guidance information storage part 121 can add and memorize discernment information on beacon device 20 newly installed, and guidance information corresponding to this discernment information, if beacon device 20 is newly installed. . This storage unit 12 is, for example, a hard disk device.
The guidance log storage unit 122 associates and stores the beacon identification information received from the terminal device 30 and the terminal device identification information of the terminal device 30A that is the identification information that identifies the terminal device 30 and that is the transmission source of the beacon identification information. do.

The guidance information update unit 13 receives the guidance information and the beacon identification information transmitted from the update terminal together with the guidance information update request via the communication unit 11, and stores them in the guidance information storage unit 121 of the storage unit 12. update the guidance information.

The guidance log update unit 14 receives the guidance log transmitted from the terminal device 30 by the communication unit 11, and stores the received guidance log in the guidance log storage unit 122 together with the terminal identification information of the terminal device 30A that is the transmission source.

The translation unit 15 translates the guidance information stored in the guidance log storage unit 122 into another language. For example, when the guidance information stored in the guidance log storage section 122 is a message written in Japanese, the translation section 15 translates the message into a language other than Japanese (for example, English, Chinese, etc.). After translation, the message after translation is stored in the guidance log storage unit 122 together with the language type representing the type of language and the message before translation. Note that the translation unit 15 may be provided in a server device different from the construction site guidance server 10, or may be provided in the terminal device 30A.

FIG. 3 is a diagram showing an example of guidance data stored in the guidance information storage unit 121. As shown in FIG.
Guidance data is data in which beacon identification information and guidance information are associated with each other. Guidance information is information about the area (transmission target area) in which the beacon device 20 to which the beacon identification information is assigned is installed, and is at least one message such as text, image (still image, video), voice, etc. . This guidance information can be expressed in multiple languages. As for characters and voices, for example, in addition to messages (guidance information) expressed in Japanese, messages expressed in other languages such as English and Chinese can also be used. As for the image, the characters and voices included in the image are expressed in any language such as Japanese, English, or Chinese. Here, for example, combinations of beacon identification information and guidance information are stored as table information (language-specific data) that differs for each language.

FIG. 4 is a schematic functional block diagram showing the functional configuration of the terminal device 30. As shown in FIG.
The terminal device 30 can be mounted on the vehicle 3, but can also be carried by a user (for example, a worker) and moved along with the movement of the user. Also, only one terminal device 30 is shown in FIG. 1, but a plurality of terminals may be provided in the construction site guidance system 1. In addition, a plurality of workers carrying terminal devices 30 may board one vehicle 3 . The terminal device 30 may be, for example, any one of a mobile phone, a smart phone, a tablet, and the like.

The communication unit 21 communicates with other devices. The communication section 21 includes a beacon signal reception section 211 and a network communication section 212 .
The beacon signal receiver 211 wirelessly receives the beacon identification information transmitted from the beacon device 20 . When the identification information transmitted from the beacon device 20 is received, the received identification information is transmitted to the construction site guidance server 10 . For example, the beacon signal receiving unit 211 receives the identification information from the beacon device 20 when the terminal device 30 moves in the tunnel 2 and reaches an area where identification information transmitted from one of the beacon devices 20 can be received. do.
The network communication unit 212 wirelessly communicates with the construction site guidance server 10 .
When wirelessly communicating with the construction site guide server 10, the network communication unit 212 can communicate directly or via a base station. If a point is installed, it is possible to communicate with the construction site guidance server 10 via this wireless access point.
The communication unit 21 can be implemented by a combination of a CPU (Central Processing Unit), a communication circuit, an antenna device, and the like.

The storage unit 22 stores various information. The storage unit 22 stores a language setting value indicating which language setting is used when the terminal device 30A outputs. Storage unit 22 includes guidance information storage unit 221 and guidance log storage unit 222 .
The guidance information storage unit 221 receives and stores the guidance information transmitted from the construction site guidance server 10 by the communication unit 21 .
The guidance log storage unit 222 stores the beacon identification information received from the beacon device 20 and the date and time when the beacon identification information was received. As for the date and time, the result of measuring the date and time by the clock function provided in the terminal device 30A can be used.
The input unit 23 can use, for example, any input device such as a touch panel, a mouse, or a keyboard, and inputs information according to the user's operation content.

The output unit 24 is a display device such as a liquid crystal display panel or an organic EL (electroluminescence) panel, a speaker, a vibrator device, or the like. At least one of the vibration outputs of the vibrator device can be output. The output unit 24 can also output (for example, transmit) various types of information to an external device.
In addition, the output unit 24 transmits the beacon identification information from the beacon device by the communication unit 21 when the terminal device 30 is carried by the user or mounted on the vehicle 3 in the information transmission area and moves with the movement of the user or the vehicle 3. Upon reception, guidance data included in guidance information corresponding to the received beacon identification information is read from the guidance information storage unit 221 and output from a display device, speaker, or the like.
In addition, the output unit 24 outputs the guidance information of the language-specific data corresponding to the language set in the own terminal device among the guidance information.
The output unit 24 outputs guidance corresponding to the beacon identification information from the guidance data received by the network communication unit 212 from the construction site guidance server 10 and stored in the storage unit 22 of the terminal device 30 in a state where communication with the construction site guidance server 10 is possible. Information is read and output, or guidance information transmitted from the construction site guidance server 10 is output in response to transmission of the received beacon identification information to the construction site guidance server 10 by the network communication unit 212 . This output may have at least one of the output functions, or may have both output functions and selectively output by either output function.

The update unit 25 updates the guide data in the guide information storage unit 221 when the communication unit 21 receives updated guide information and beacon identification information from the construction site guide server 10 . The update may be any of rewriting, deletion, etc., when adding information.
The control unit 26 controls each unit in the terminal device 30A. For example, the control unit 26 sets the language of the terminal device 30A according to the operation content from the input unit 23, and causes the storage unit 22 to store the language setting value specifying the language to be used.

30 A of terminal devices input the beacon identification information of the beacon apparatus provided in the area|region of the object which transmits guidance information and the said guidance information.
The terminal device 30A is a terminal that can be operated by an administrator who manages information to be transmitted in the construction site guidance system 1 and that can communicate with the construction site guidance server 10. Either one may be used, and a dedicated terminal device may be used separately from the terminal device 30 . In this embodiment, a case where the terminal device 30A is used as an update terminal will be described.
The terminal device 30A has an input unit capable of inputting guidance information and the beacon identification information of the beacon device 20 provided in the area to which the guidance information is to be transmitted, and transmits various types of input information to the construction site guidance server 10. and a communication unit for A PC, a smart phone, a mobile phone, or the like can be used as this update terminal.
The addition of this guidance information can be additionally registered by having the manager who manages the construction of the tunnel 2 input or transmit it from the terminal device 30A. When registering or updating guidance information, for example, input devices such as a keyboard and a mouse connected to the construction site guidance server 10 are used so that the manager of the construction site of the tunnel 2 can input. can be That is, the guidance data stored in the construction site guidance server 10 can be directly updated without using the terminal device 30A.

In this way, by registering new guidance information or updating registered guidance information, it is possible to transmit guidance information even at the extended location in accordance with the extension of the tunnel 2 due to excavation. Become. Moreover, according to extending a tunnel, it can also update about the guidance information in the beacon apparatus 20 already installed. For example, the beacon device 20b is installed at a position about 300 m from the pithead 2a, and when the construction progresses until the distance from the pithead 2a to the face 2b is about 500m, it is installed at a position about 200m away from the face 2b. However, when the tunnel construction progresses to some extent and the distance from the tunnel entrance 2a to the face 2b reaches about 1000 m, the beacon device 20b is about 700 m from the face 2b. In such a case, in the beacon device 20b, when transmitting the guidance information according to the distance from the face 2b, according to the progress of the construction, so as to update the guidance information for the identification information of the beacon device 20b. good too.

Returning to FIG. 1, the beacon device 20a is installed near the entrance 2a of the tunnel 2, and as guidance information corresponding to the beacon device 20a, for example, guidance information such as "the speed limit is 15 km" can be set. can. As a result, by notifying the vehicle 3 entering the tunnel 2 of this guide information at the stage of entering the tunnel 2, it becomes possible for the vehicle 3 to recognize the speed limit in the tunnel 2, and the traveling speed in the tunnel. can be urged to comply with the speed limit.

The beacon device 20b is, for example, installed at a position of about 300 m from the tunnel entrance 2a to the face 2b side, on the inner circumference side of the concrete lining constructed in the tunnel 2 (lighting device, ventilation equipment, disaster prevention equipment, etc.). When construction work is being carried out, guidance information such as "honk signal" can be set. Thereby, it is possible to inform in advance that the vehicle 3 will pass through the vicinity to the worker who installs various facilities. A worker who installs various facilities can proceed with the work assuming that the vehicle 3 will pass.

The beacon device 20c can set guidance information such as "passing under the river" when there is a river above it, for example, at a position about 700 m from the tunnel entrance 2a to the face 2b side. Thereby, the crew of the vehicle 3 passing near the position of the beacon device 20c can be made to recognize that the vehicle is traveling below the river. This allows workers to recognize that they are passing through an area where water can form in the mine. For example, construction of the tunnel 2 includes drilling, blasting, removal of muck, installation of shoring, concrete spraying, installation of rock bolts, waterproofing, concrete lining, and the like. For example, if the tunnel 2 is located under a river, water is more likely to occur inside the tunnel 2 when the concrete spraying work is completed than when the lining is completed. In such cases, workers in the vehicle can be notified that they are passing under a river. As a result, workers can pass through while recognizing the possibility that water may occur, and in some cases, check the condition of the inner peripheral surface of the tunnel 2 and take necessary measures. is also possible.

20 d of beacon devices can output "1000 m from the wellhead" etc. in the position of about 1000m from the wellhead 2a to the face 2b side, for example. As a result, the worker of the vehicle 3 passing near the beacon device 20d can recognize that it has moved to a position of 1000 m from the mine mouth, and is aware of how far the vehicle 3 is to the face 2b. can be run.

Here, the guidance information may be information that can be output from the terminal device 30, and may be, for example, text information, voice information, information for vibrating the vibrator function of the terminal device 30, or the like. When the guidance information is text information, the text information can be displayed on the display screen of the terminal device 30. Also, if the terminal device 30 has a function to read the text information aloud, the text information can be read out through a speaker. can emit sound from

Next, the operation of the construction site guidance system 1 described above will be described. FIG. 5 is a sequence diagram explaining the operation of the construction site guidance system 1. As shown in FIG. Here, the terminal device has a language setting function as one of the main body setting functions. It is set by being selected by the user.

The beacon device 20 transmits the beacon identification information assigned to itself in the transmission target area in which it is provided (step S151).

The control unit 26 of the terminal device 20A determines whether communication with the construction site guidance server 10 is possible through the network communication unit 212 of the communication unit 21 (step S251). For example, the control unit 26 determines whether or not network connection is possible by determining whether or not communication with the construction site guidance server 10 is possible.
In the case where communication with the construction site guidance server 10 is possible (network connection is possible), the update unit 25 requests the construction site guidance server 10 to transmit guidance information through the communication unit 21 . In response to this request, the construction site guide server 10 transmits the guide data stored in the guide information storage unit 121 to the terminal device 20A (step S351).
When the terminal device 20A receives the guidance data from the construction site guidance server 10 (step S252), the terminal device 20A stores the received guidance data in the guidance information storage unit 221. FIG.
On the other hand, when the terminal device 20A is in a state in which network connection is not possible (for example, out of service area), the control unit 26 stores the guidance information from the guidance information storage unit 221 in a predetermined memory so that it can be output to the output unit 24. Read out to the area (step S253).

Here, even if the beacon identification information is not received from the beacon device 20, by receiving the guidance data from the construction site guidance server 10 in a state where the network connection is possible, the beacon at the destination of the terminal device 30A. Even in an environment in which network connection is not possible when identification information is received, guidance information can be output using previously received guidance data.
For example, the terminal device 30A can communicate wirelessly with the construction site guide server 10 in underground spaces, tunnels (mountain tunnels, subway tunnels, shield tunnels, etc.), and facilities (dams, parking lots, etc.) provided in mountainous areas. There may be areas where communication is not possible. In such a case, for example, before entering an area such as an underground space, by executing steps S251 and S252 in an area near the entrance where network connection is possible, the latest information can be obtained from the construction site guide server. 10 and storing the guidance data in the guidance information storage unit 221, the terminal device 30A receives the beacon identification information from the beacon device 20 in an area where wireless communication with the construction site guidance server 10 is not possible. However, the guidance information can be output by reading the guidance information from the guidance information storage unit 221 . In addition, for example, at a construction site, etc., in the morning, during lunch, during breaks, or when performing work outside the underground space, once you leave the area where network connection is not possible such as the underground space, wait for a certain period of time, and then try again. Since the terminal device 30A may enter an underground space or the like, the terminal device 30A communicates with the construction site guidance server 10 at the timing of exiting (or before entering) the underground space, etc., and receives guidance data. Guidance information can be updated several times during a day.

On the other hand, when newly registering (adding) guidance information or changing already registered guidance information, the terminal device 30B accepts input of additional content or update content input by the user via the input device. It receives as guidance information together with the beacon identification information of the beacon device 20 provided in the target area for transmitting this guidance information (step S281). When the guidance information is input, the control unit 26 of the terminal device 30B translates the guidance information included in the guidance information into multiple languages (step S282). For this translation, if the terminal device 30B is equipped with a translation function, the translation function is used to translate the guidance information into another language. If the terminal device 30B does not have a translation function, the guide information may be transmitted to an external server that translates the guide information and receive the translated guide information. Further, if the construction site guidance server 10 has a translation function, the guidance information is transmitted to the construction site guidance server 10 without being translated by the terminal device 30A, and is translated by the construction site guidance server 10. may For this translation, for example, when the input guidance information is in Japanese, it is translated into other languages such as English and Chinese. This guidance information may be text data input from a keyboard, touch panel, or the like, or may be data converted from voice data input from a microphone or the like into text data.
The language to be translated into may be determined in advance or may be designated by the user of the terminal device 30B.

Here, "new addition" is, for example, when the beacon device 20 is newly installed in the construction site guidance system 1, or when the guidance information to be transmitted in the already installed beacon device 20 is unregistered , is a function for newly registering guidance information, and "Change" is a function for changing the contents of already registered guidance information to different guidance information.
When the guidance information is translated, the control unit 26 of the terminal device 30B transmits the guidance information before translation, the guidance information after translation, and the beacon identification information to the construction site guidance server 10 as guidance information for newly adding or changing the guidance information. 21 (step S283).

Here, the terminal device 30B can perform the processing from step S281 to step S283 (additional content is input of update content) at any timing. For example, when a scene to register or add information arrives, input can be made each time. As a result, the input information is transmitted to the construction site guidance server 10, and the guidance information stored in the construction site guidance server 10 is updated in real time.

When the guidance information updating unit 13 of the construction site guidance server 10 receives the guidance information together with the beacon identification information from the terminal device 30B (step S352), the guidance information update unit 13 stores the received guidance information together with the beacon identification information in the guidance information storage unit 121. Registration processing is performed (step S353). Here, when the guidance information is newly added, it is additionally stored in the guidance information storage unit 121, and when the guidance information is changed, among the already stored guidance information, the guidance information matching the beacon identification information is stored. is updated by overwriting the guidance information of the guidance information received in step S352. It should be noted that the guide information before change may be left as a log.
Also, if the newly registered or updated guide information includes character string information, voice data that reads out the character string information by voice may be generated and added to the guide information and stored.

On the other hand, 20 A of terminal devices determine whether the beacon identification information was received from the beacon apparatus 20 (step S254).
If the beacon identification information has not been received, the process of step S254 is executed again after a certain period of time has elapsed.

On the other hand, when the beacon identification information is received, it is determined whether or not network connection is established (step S255).
If network connection is established, the control unit 26 transmits the received beacon identification information to the construction site guidance server 10 through the communication unit 21 (step S256).

When the beacon identification information is received from the terminal device 20A, the construction site guidance server 10 reads the guidance information corresponding to the received beacon identification information from the guidance information storage unit 121 (step S355), and transmits it to the terminal device 20A (step S356). ).
When the control unit 26 of the terminal device 30A receives the guidance information (step S257), the output unit 24 outputs the guidance information included in the received guidance information (step S259). Here, the guidance information is displayed as characters or images on the screen in the language set in the main body setting of the terminal device 30A, or the guidance information is voiced by the speaker or the like in the language set in the main body setting of the terminal device 30A. is output as As for the sound output from the speaker, read-out data may be output by a read-aloud function for reading out the character string information included in the guidance information. This reading data may be generated by the construction site guidance server 10 and included in the guidance information, and may be output from a speaker. Reading data may be generated from the included character string information and output from a speaker. It should be noted that the read-out data may be generated in a language according to the language setting of the main body so that the read-out data can be read out in the language according to the language setting.
On the other hand, when the terminal device 30A is not connected to the network, among the guidance information read from the guidance information storage unit 221, the terminal device 30A stores the guidance information included in the guidance information corresponding to the received beacon identification information. It is read from the unit 221 (step S258) and output by the output unit 24 (step S259).

Here, if the guide information has been received in advance in step S252, the process of steps S256, S354 to S356, and S257 is not performed, and in step S255, regardless of whether or not the network is connected, Instead, the guidance information stored in the guidance information storage unit 221 may be referenced to output the guidance information. In this case, guidance information can be output using guidance information received in advance.
Further, even if the guide information has been received in advance in step S252, the processing from step S256 and step S354 to step S356 and step S257 may be executed. In this case, even if the guidance information is updated by the updating terminal (terminal device 30B) after the guidance information is received in step S252, the guidance information corresponding to the beacon identification information is requested in step S256, and the guidance information is updated. The guide information registered at that time can be output after being received in step S257. Therefore, the latest guidance information can be output.

Next, the control unit 26 of the terminal device 30A stores the received beacon identification information and the date and time when the beacon identification information was received as a guidance log in the guidance log storage unit 222 (step S230).
Next, the control unit 26 of the terminal device 30A determines whether or not to end the guidance. If the guidance is not ended, the process proceeds to step S254. It is determined whether or not it is set (step S232). The control unit 26 of the terminal device 30A terminates the process when not connected to the network, and transmits the guidance log stored in the guidance log storage unit 222 to the construction site guidance server 10 when connected to the network. do.
Upon receiving the guidance log from the terminal device 30A, the guidance log updating section 14 of the construction site guidance server 10 stores the received guidance log in the guidance log storage section 122 (step S357).

Here, since the guidance log is stored in step S230 or step S357, it is possible to ascertain what route the user carrying the terminal device 30 has taken, and the action history of the user. .
By using this guidance log, for example, when there are more terminal devices 30 that have received the beacon identification information of the beacon device 20c than other beacon devices 20, the opportunity for workers to work near the beacon device 20c It can be understood that there are many
In addition, in a construction site, if guidance information is to be transmitted in a target area for guidance information, if it is desired to change the guidance information according to the progress of the work process at the site, or if it is desired to change the guidance information according to the time zone such as morning, noon, evening, etc., a new By updating the guidance information from the terminal device 30A at an arbitrary timing, such as when a cautionary note occurs, the terminal device 30 that receives the updated beacon identification information can output the updated guidance information. .

In addition, by referring to the guidance log, for example, in a period when it is not desired to approach the vicinity of the beacon device 20d as much as possible, whether the number of terminal devices 30 receiving the beacon identification information of the beacon device 20d exceeds a certain number It is possible to grasp whether or not, and after updating the guidance information to guide so as not to approach the vicinity of the beacon device 20d, guidance such as the number of workers approaching the vicinity of the beacon device 20d has decreased It is also possible to grasp the effect on information.

In addition, when a worker collapses in the field, it is also possible to grasp the route through which the worker collapsed.
Also, it is possible to analyze behavior by utilizing the guidance log.

In this way, at the construction site of the tunnel 2, a beacon device is placed, for example, in a dangerous place, and when a car approaches the place, sound, screen, vibration, etc. are output to the terminal device 30 such as a smartphone. , can be reminded about dangerous places or places that need attention. Also, in a linear structure such as the tunnel 2, there is a certain distance, and by installing the beacon device 20 at positions such as 500 m, 1000 m, and 1500 m from the wellhead, it is possible to announce the location. By installing a beacon device 20 at a portion of the tunnel 2 where there is a river or structure directly above, it is also possible to clearly indicate that the river or structure is directly above.
For example, when the current position of the vehicle 3 is in the vicinity of the tunnel 2a, the terminal device 30 outputs the guidance information "the speed limit is 15 km" (reference numeral 20a1 in FIG. When it moves to about 300m (the vicinity of the beacon device 20b), the terminal device 30 outputs the guidance information of "a horn signal" (FIG. 1, code|symbol 20b1). Furthermore, when the current position of the vehicle 3 moves from the tunnel 2a to about 700 m (in the vicinity of the beacon device 20c), the terminal device 30 outputs the guidance information "pass under the river" (Fig. 1, symbol 20c1), and the vehicle When the current position of 3 moves to about 1000m from the wellhead 2a (near the beacon device 20d), the terminal device 30 outputs the guidance information "1000m from the wellhead" (Fig. 1, reference numeral 20d1). Thereby, the worker can be notified of the guidance information according to the position in the tunnel 2 in which the vehicle 3 is running.

In addition to the above, the location where the beacon device 20 is installed is, for example, the entrance of the construction site in the tunnel 2, or the vicinity of the portal 2a outside the tunnel 2, the portal 2a of the tunnel, the center (with the lining It may be installed before and after the semi-cylindrical concrete formwork for forming.

According to the embodiment described above, by installing the beacon device 20 in the tunnel 2, it is possible to grasp the current position where the vehicle 3 is traveling. Therefore, it is not necessary to measure the terminal device 30 by GNSS (Global Navigation Satellite System) or GPS, and LTE (Long Term Evolution), Wi-Fi (Wi-Fi (registered trademark)), etc. are installed. Since it is not necessary to install a new access point for the purpose of detecting location information for distributing guidance information, it can be easily installed in any position, and once installed, identification information can be transmitted by radio waves. I can do it. And it becomes possible by using the identification information transmitted from a beacon apparatus to identify the installation position. Therefore, it is possible to select, install, and use any location in the tunnel 2 where the guide information is desired to be notified. Moreover, by adjusting the radio wave intensity of the radio waves transmitted from the beacon device 20, it is possible to set the area to be notified, and to adjust and notify the optimum range.

In addition, in the above-described embodiment, by utilizing the long travel time in the mine, it is possible to realize both attention calling and on-site introduction. For example, as tunnel construction progresses, the distance from the pit mouth to the face increases accordingly. Therefore, different information may be transmitted according to the extension of the distance from the wellhead to the face. For example, if the distance from the pithead to the face is extended from 500m to 1000m, the tunnel construction manager will need to consider that the travel time will be longer as the travel distance from the pithead to the face becomes longer. It may be updated so as to increase the matters to be alerted in consideration of the length of travel time and the contents to be introduced to the site. For example, if the distance from the pithead to the face is 500m, output one item of caution at the point 150m from the pithead. Two items of notes may be output at the point of . In this case, even if the number of notes to be output (or the reading time) increases, it is possible to secure time for checking the notes that have been output before reaching the face.

In addition, in the construction site guidance system 1 described above, the beacon device 20 can notify a determined announcement by placing it in a determined place, but besides this, multilingual support is also easy. . For example, if English is set as the display language of the smartphone, the announcement can be made in English, and if Chinese is set as the display language, the announcement can be made in Chinese. In recent years, the internationalization of construction sites is progressing, so we can expect its utilization. Since it is easy to set up such multilingualization, it is possible to flexibly cope with the internationalization of construction sites.

In that case, a program for realizing this function may be recorded in a computer-readable recording medium, and the program recorded in this recording medium may be read into a computer system and executed. It should be noted that the "computer system" referred to here includes hardware such as an OS and peripheral devices. The term "computer-readable recording medium" refers to portable media such as flexible discs, magneto-optical discs, ROMs and CD-ROMs, and storage devices such as hard discs incorporated in computer systems. Furthermore, "computer-readable recording medium" means a medium that dynamically retains a program for a short period of time, like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. It may also include something that holds the program for a certain period of time, such as a volatile memory inside a computer system that serves as a server or client in that case. Further, the program may be for realizing a part of the functions described above, or may be capable of realizing the functions described above in combination with a program already recorded in the computer system.
