Effects of the Invention

[0023] According to the construction site information providing system of the present invention, a management node stores the location information of a plurality of construction sites, and transmits the location information of a predetermined construction site where construction-related personnel work among the stored location information of the construction sites to a communication node held by the construction-related personnel. The communication node receives the location information of the predetermined construction site where the construction-related personnel work transmitted from the management node, and outputs the received location information of the predetermined construction site. Therefore, each construction-related personnel working or planning to work at each construction site can be notified of the location information of that construction site from the management node, and by the communication node outputting the location information of the construction site, the location of each construction site where those construction-related personnel work or plan to work can be known.

[0024] In a construction site information providing system where the location information is address information of a predetermined construction site where construction-related personnel work, map information for outputting the location of the predetermined construction site where construction-related personnel work on a map, and route information indicating a route from the current location where the construction-related personnel are located to the predetermined construction site where the construction-related personnel work, each construction-related personnel working or planning to work at each construction site can be notified of the address, map information, and route of that construction site from the management node, and by the communication node outputting the address, map information, and route of the construction site, the address, map information, and route of each construction site where those construction-related personnel work or plan to work can be known. Even if a construction-related person is in charge of a large number of construction sites, the construction site information providing system can accurately recognize the location of the construction site by looking at the address, map information, and route, and can reach those construction sites without getting lost.

[0025] The management node receives the construction site images of each construction site captured by those web cameras, and transmits the construction site images of a predetermined construction site where construction-related personnel work among the received construction site images of each construction site to the communication node held by the construction-related personnel. The communication node receives the construction site images of the predetermined construction site where construction-related personnel work transmitted from the management node, and outputs the received construction site images of the predetermined construction site. The construction site information providing system can inform each construction-related personnel working at the construction site of the current situation, scale, and structure of the construction site by the management node transmitting the construction site images of the construction site where the construction-related personnel work to the communication node and the communication node outputting the construction site images, enabling each construction-related personnel to know the current situation, scale, and structure of each construction site.

[0026] The management node acquires the weather information of multiple work sites for each construction site, and transmits the weather information of a predetermined construction site where construction-related personnel work among the acquired weather information to the communication node held by the construction-related personnel. The communication node receives the weather information of the predetermined construction site where construction-related personnel work transmitted from the management node, and outputs the received weather information of the predetermined construction site. The construction site information providing system can inform each construction-related personnel working at the construction site of the weather information of the construction site by the management node transmitting the weather information of the construction site where the construction-related personnel work to the communication node and the communication node outputting the weather information received from the management node, enabling each construction-related personnel to know the weather information of each construction site where they plan to work.

[0027] The construction site information providing system, where the weather information is the current weather of the vicinity including the construction site, the weather forecast of the vicinity including the construction site, and the rain cloud radar information of the vicinity including the construction site, can inform each construction-related personnel working at each construction site of the current weather, weather forecast, and rain cloud radar information of the vicinity including the construction site from the management node, and by the communication node outputting the current weather, weather forecast, and rain cloud radar information of the vicinity including the construction site, those construction-related personnel can know the current weather, weather forecast, and rain cloud radar information of the vicinity including each construction site where they plan to work.

[0028] Based on the weather information of each construction site obtained by the management node, it determines the feasibility of construction work at each construction site, and transmits the determined feasibility of construction work at each construction site to the communication nodes held by the construction-related personnel. The communication node receives the feasibility of construction work at each construction site transmitted from the management node and outputs the received feasibility of construction work at each construction site. The construction site information providing system can avoid the risk of construction work carried out in bad weather and ensure the safety of the construction site by the management node determining the feasibility of construction work at each construction site based on the weather information of each construction site and the communication node outputting the received feasibility of construction work at each construction site. The construction site information providing system can prevent the occurrence of danger to the construction-related personnel and enable the construction-related personnel to carry out construction work safely.

[0029] When a disaster of a certain level or above occurs at a predetermined construction site by the management node, it transmits safety confirmation information to the communication node held by the construction-related personnel working at the disaster-occurring construction site. When the communication node receives the safety confirmation information transmitted from the management node, it transmits the safety reply information of the construction-related personnel holding the communication node to the management node. When the management node receives the safety reply information of the construction-related personnel from the communication node by the safety reply information transmission means, the construction site information providing system that outputs the safety reply information of the construction-related personnel can quickly confirm the safety of the construction-related personnel working at the disaster-occurring construction site and can carry out appropriate life-saving assistance in case of a disaster by the management node transmitting safety confirmation information to the communication node and the communication node transmitting safety reply information to the management node. When the construction site information providing system receives the safety reply information of the construction-related personnel from the communication node, since the management node outputs the safety confirmation information of the construction-related personnel, the managers, on-site responsible persons, on-site supervisors, etc. among the construction-related personnel can know the safety of the construction-related personnel for each disaster-occurring construction site, and the managers, on-site responsible persons, on-site supervisors, etc. can accurately grasp the safety of the construction-related personnel for each disaster-occurring construction site.

[0030] The management node receives the disaster occurrence site images of the construction site during a disaster from a web camera, and transmits the disaster occurrence site images of a predetermined disaster occurrence construction site where construction-related personnel work among the received disaster occurrence site images of each construction site to the communication node held by the construction-related personnel. The communication node receives the disaster occurrence site images of the disaster occurrence construction site where construction-related personnel work transmitted from the management node, and outputs the received disaster occurrence site images of the predetermined disaster occurrence construction site. In the construction site information providing system, the management node transmits the disaster occurrence site images of the construction site received from the web camera to the communication node, and the communication node outputs the disaster occurrence site images, so that it is possible to notify construction-related personnel of the presence or absence of a disaster, and construction-related personnel can know the damage situation and safety of the construction site due to the disaster, and construction-related personnel can evacuate safely and quickly from the disaster occurrence site, ensuring the safety of construction-related personnel at the disaster occurrence site.

[0031] Based on the disaster occurrence construction site images of the construction site received by the management node, the management node determines the feasibility of construction work at that construction site, and transmits the determined feasibility of construction work at each construction site to the communication node held by the construction-related personnel. The communication node receives the feasibility of construction work at each construction site transmitted from the management node, and outputs the received feasibility of construction work at each construction site. In the construction site information providing system, since the feasibility of work at the construction site after a disaster is determined based on the determination of the management node on the feasibility of construction work, it is possible to avoid the risk of determining the feasibility of work based on the judgment of individual construction-related personnel, and ensure the safety of the work of construction-related personnel at the disaster occurrence site.

[0032] When vibrations equal to or above the set level among the vibrations transmitted from the vibration sensor by the management node occur, the vibration information is transmitted to the communication node held by the construction worker working at the construction site where the vibrations equal to or above the set level have occurred. Also, when sounds equal to or above the set level among the sounds transmitted from the microphone occur, the sound information is transmitted to the communication node held by the construction worker working at the construction site where the sounds equal to or above the set level have occurred. The construction site information providing system that receives the vibration image information of the construction site where the construction worker works transmitted from the management node by the communication node, outputs the received vibration information of the predetermined construction site, receives the sound information of the construction site where the construction worker works transmitted from the management node, and outputs the received sound information of the predetermined construction site. When abnormal vibrations equal to or above the set level occur at the construction site, since the communication node outputs the vibration information of the construction site where the construction worker works, the construction worker working at the predetermined construction site can know the abnormality caused by the vibrations at the construction site from the vibration information, and the construction worker who has detected the danger can safely and quickly evacuate from the construction site, and the safety of the construction worker can be ensured. When abnormal sounds equal to or above the set level occur at the construction site, since the communication node outputs the sound information of the construction site where the construction worker works, the construction worker working at the predetermined construction site can know the abnormality caused by the noise at the construction site from the sound information, and the construction worker who has detected the danger can safely and quickly evacuate from the construction site, and the safety of the construction worker can be ensured.

[0033] When a construction worker enters a construction site where the communication node is located and the construction workers who own it are working, the construction worker entry information is sent to the management node, and the construction worker information of the entering construction worker is sent to the management node. The management node stores the construction worker entry information sent from the communication node for each construction site, aggregates the number of entering construction workers for each construction site based on the entry information sent from the communication node, outputs the aggregated number of entering workers in a state classified for each construction site, and outputs the stored construction worker entry information in a state classified for each construction site. In the construction site information providing system, since the management node aggregates the number of entering construction workers for each construction site and outputs the aggregated number of entering workers for each construction site, managers, site supervisors, on-site supervisors, etc. among the construction workers can know the number of entering workers for each construction site, and managers, site supervisors, on-site supervisors, etc. can accurately grasp the number of entering workers for each construction site. The construction site information providing system enables managers, on-site supervisors, etc. among the construction workers to know various information about the construction workers who have entered each construction site and accurately grasp the construction workers who have entered each construction site by the management node outputting the construction worker entry information of the construction workers who have entered each construction site in a state classified for each construction site.

[0034] When a construction worker leaves the construction site where the communication node is located and is possessed by the construction-related person, the communication node transmits the departure information of the construction worker to the management node, and transmits the construction-related person information of the departing construction worker to the management node. The management node stores the construction worker departure information transmitted from the communication node for each construction site, aggregates the number of departing construction workers for each construction site based on the departure information transmitted from the communication node, outputs the aggregated number of departing workers for each construction site, and outputs the stored construction worker departure information in a state divided for each construction site. Since the management node of the construction site information providing system aggregates the number of departing construction workers for each construction site and outputs the aggregated number of departing workers for each construction site, managers and site supervisors among the construction workers can know the number of departing workers for each construction site, and managers and site supervisors can accurately grasp the number of departing workers for each construction site. The construction site information providing system outputs the construction worker departure information of the construction workers who have left each construction site in a state divided for each construction site, so that managers and site supervisors among the construction workers can know various information of the construction workers who have left each construction site, and managers and site supervisors can accurately grasp the construction workers who have left each construction site.

[0035] The construction site information providing system capable of outputting a plurality of various gadgets in the management node and the communication node and capable of changing an existing gadget to another gadget in the management node and the communication node can open a plurality of various sites by using the plurality of various gadgets output to the management node and the communication node, and construction-related persons can use the site to purchase items, conduct various searches, various investigations, and the like. Since the construction site information providing system can change an existing gadget to another gadget in the management node and the communication node, it is possible to select a gadget useful for construction-related persons and open a site necessary for construction work.

[0036] A plurality of information display blocks can be output to one screen of a communication node, and at least two of the location information of the construction site, the current construction site image of the construction site, the weather information of the construction site, the information on the feasibility of construction work at each construction site, and the disaster occurrence site image of the construction site are separately output to each information display block output to one screen. In the construction site information providing system, various information and images are output to the plurality of information display blocks output to one screen, so that construction-related personnel can view a plurality of information on one screen and can know a plurality of information at once on one screen.

[0037] In a construction site information providing system in which a management node and those communication nodes form a network via a predetermined blockchain, the management node and those communication nodes form a network via the blockchain, and the location information of the construction site, the current construction site image of the construction site, the weather information of the construction site, the information on the feasibility of construction work at each construction site, and the disaster occurrence site image of the construction site are stored in the management node as transaction data. Therefore, while preventing the falsification of the location information of the construction site, the current construction site image of the construction site, the weather information of the construction site, the information on the feasibility of construction work at each construction site, and the disaster occurrence site image of the construction site, it is possible to save an accurate history of the location information of the construction site, the current construction site image of the construction site, the weather information of the construction site, the information on the feasibility of construction work at each construction site, and the disaster occurrence site image of the construction site.

The central processing unit of the tablet 11a receives the construction site information and the construction site image of the construction site 17a transmitted from the management server 14 by the construction site image transmission means (construction site image reception means).

[0086] The central processing unit of the tablet 11a that has received the construction site information and the construction site image of the construction site 17a from the management server 14 outputs (displays) the construction site image output screen 22 shown in FIG. 5 on the touch panel 15 (construction site image output means). On the construction site image output screen 22 of FIG. 5, a construction site information output area 22a that outputs (displays) construction site information (name of the construction site, address of the construction site, telephone number and email address of the construction site, construction period of the construction site, name of the person in charge of the construction site, etc.), a construction site image output area 22b that outputs (displays) the current construction site image of the construction site 17a, a menu screen button 22c, and an end button 22d are output (displayed). In the construction site image output screen 22 of FIG. 5, one construction site image is illustrated, but a plurality of construction site images of the construction site 17a taken by each Web camera 15 are output (displayed) in the construction site image output area 22d.

[0087] In the construction site information providing system 10, the management server 14 (management node) transmits the current construction site image of a predetermined construction site 17a where construction-related personnel work among the construction site images of each construction site taken by those Web cameras 15 to the tablet 11a (communication node), and the tablet 11a outputs (displays) the current construction site image of the predetermined construction site 17a received from the management server 14. Therefore, each construction-related person working at each construction site can be informed of the current status, scale, and structure of the current construction site, and each construction-related person can know the current status, scale, and structure of each construction site.

[0088] FIG. 6 is a diagram showing an example of the weather information output screen 23 output (displayed) on the touch panel 15 of the tablet 11a. In FIG. 6, the display of each data output to each output area is omitted. To view the weather information of the construction site 17a where construction-related personnel are working or planning to work, tap the weather information window 20c on the menu screen 20. When the weather information window 20c is tapped, a previously described construction site selection screen (not shown) is output (displayed) on the touch panel 15 of the tablet 11a.

[0089] In the construction site input area of the construction site selection area, enter the name and address of the construction site 17a where you are working or the construction site 17a where you plan to work, or select the name of the construction site where you are working or plan to work from the construction site name pull-down menu, and then tap the construction site determination button. When the construction site determination button is tapped, the central processing unit of the tablet 11a uses the URL of the management server 14 to access and log in to the management server 14 via the Internet, and the construction site specific information (construction site specific identifier) corresponding to the construction site name and construction site address entered in the construction site input area, or the construction site specific information (construction site specific identifier) corresponding to the construction site name selected from the construction site name pull-down menu, and a weather information transmission request signal are transmitted to the management server 14 together with the communication node specific information (communication node specific identifier).

[0090] The management server 14 that has received the construction site specific information, communication node specific information, and weather information image transmission request signal from the tablet 11a accesses the regional weather observation system (AMeDAS) of the Japan Meteorological Agency, rainfall information services, weather information sites, etc., and acquires the weather information in the vicinity including the construction site 17a (weather information acquisition means). The management server 14 transmits the acquired weather information in the vicinity including the construction site 17a, the construction site information, and the construction site image of the current construction site 17a to the tablet 11a via the Internet (weather information transmission means). The weather information includes the current weather in the vicinity including the construction site 17a, the weather forecast in the vicinity including the construction site 17a, and the rain cloud radar information in the vicinity including the construction site 17a.

[0091] Next, the management server 14 refers to the warning level of the Japan Meteorological Agency, which is the meteorological information of the construction site 17a (each construction site) obtained by the meteorological information acquisition means, and determines the feasibility of construction work at each construction site based on the warning level (first construction work feasibility determination means). For example, when the warning level is 5 (heavy rain special warning, flood occurrence information), warning level 4 (landslide disaster warning information, flood danger information, high wave special warning), or warning level 3 (heavy rain warning, flood warning, flood warning information), it is determined that construction work at the construction site is not feasible. When the warning level is 2 (heavy rain advisory, flood advisory, flood advisory) or warning level 1 (early advisory), it is determined that construction work at the construction site is feasible. The management server 14 transmits the feasibility of construction work at each construction site determined by the first construction work feasibility determination means to the tablet 11a via the Internet (first construction work feasibility transmission means).

[0092] The management server 14 stores (stores) in a mass storage area (or a mass hard disk) (block) in a state where the meteorological information, construction site information, and construction site image of the current construction site 17a around the obtained construction site 17a are associated with the acquisition date and time and construction site specific information (construction site specific identifier) together with a predetermined hash value (meteorological information storage means). At the same time, the meteorological information around the construction site 17a including the construction site 17a, the construction site image of the current construction site 17a, and the feasibility of construction work at the construction site 17a determined by the first construction work feasibility determination means are stored (stored) in a mass storage area (or a mass hard disk) (block) in a state where they are associated with the determination date and time and construction site specific information (construction site specific identifier) together with a predetermined hash value (first construction work feasibility storage means).

[0093] The central processing unit of the tablet 11a receives the weather information, construction site information, and the construction site image of the current construction site 17a in the vicinity of the construction site 17a including the construction site 17a transmitted from the management server 14 by the weather information transmission means (weather information receiving means), and receives the permission or non - permission of the construction work at the construction site 17a transmitted from the management server 14 by the construction work permission first transmission means (construction work permission first receiving means). The central processing unit of the tablet 11a outputs the weather information of a predetermined construction site 17a received from the management server 14 by the weather information receiving means (weather information output means), and outputs the permission or non - permission of the construction work at the construction site 17a received from the management server 14 by the construction work permission first receiving means (construction work permission first output means). Sunny On the weather information output screen 23 shown in FIG. 6, there are output (displayed): a construction site information output area 23a that outputs (displays) construction site information (name of the construction site, address of the construction site, telephone number and email address of the construction site, construction period of the construction site, name of the person in charge of the construction site, etc.); a construction site image output area 23b that outputs (displays) the construction site image of the current construction site; a weather information output area 23c that outputs (displays) weather information; a construction work permission output area 23d that outputs (displays) the permission or non - permission of the construction work; a menu screen button 23e; and an end button 23f. The construction site image output in the construction site image output area 23b is the construction site image of the current construction site 17a taken by the web camera 15 at the time when the weather information was acquired. In the weather information output area 23c, there are output (displayed): a current weather output area 23g that outputs (displays) the current weather in the vicinity including the construction site; a weather forecast output area 23h that outputs (displays) the weather forecast in the vicinity including the construction site; and a rain cloud radar information output area 23i that outputs (displays) the rain cloud radar information in the vicinity including the construction site. In the construction work permission output area 23g, either "construction work possible" or "construction work impossible" at the current construction site 17a is output (displayed).

[0094] The construction site information providing system 10 enables the management server 14 (management node) to transmit the weather information of a predetermined construction site where construction-related personnel are working or planning to work to the tablet 11a (communication node), and the tablet 11a outputs the weather information received from the management server 14, so that each construction-related personnel working or planning to work at each construction site can be informed of the weather information of that construction site (the current weather, weather forecast, rain cloud radar information in the vicinity including the construction site), and each construction-related personnel working or planning to work at each construction site can know the weather information of that construction site (the current weather, weather forecast, rain cloud radar information in the vicinity including the construction site).

[0095] The construction site information providing system 10 enables the management server 14 (management node) to refer to the warning level of the Meteorological Agency, which is the weather information of each construction site, judge the feasibility of construction work at each construction site based on the warning level, and the tablet 11a (communication node) outputs the feasibility of construction work at each construction site received, so that the risk of construction work carried out in bad weather can be avoided, and the safety of the construction site can be ensured. The construction site information providing system 10 can prevent the occurrence of danger to construction-related personnel and enable construction-related personnel to carry out construction work safely.

[0096] FIG. 7 is a diagram showing an example of the safety confirmation transmission screen 24 output (displayed) on the touch panel 15 of the tablet 11, and FIG. 8 is a diagram showing an example of the safety confirmation screen 25 output (displayed) on the display 19 of the management server 14. In FIGS. 7 and 8, the display of each data output to each output area is omitted. The management server 14 accesses the earthquake observation system installed in the prefecture, the aforementioned regional weather observation system (AMeDAS), rainfall information service, weather information site, etc., and monitors whether disasters such as earthquakes, storms, and landslides have occurred in the vicinity including a predetermined construction site. When a disaster occurs in the vicinity including a predetermined construction site, the management server 14 acquires the disaster information (seismic intensity, weather, warning level, etc.) in the vicinity including the construction site where the disaster occurred from the above-mentioned systems and sites (disaster information acquisition means).

[0097] When a disaster occurs in the vicinity including the construction site 17a and the disaster is at or above the set level, the central processing unit of the management server 14 transmits, via the Internet, for example to the first personal computer 13a, a disaster-occurrence construction-site shooting signal for shooting an image of the disaster-occurrence construction site 17a at the time of or immediately after the disaster by the web camera 15 installed at the disaster-occurrence site 17a. The central processing unit of the first personal computer 13a that has received the disaster-occurrence construction-site shooting signal from the management server 14 causes the web camera 15 to shoot an image of the disaster-occurrence construction site 17a. The image of the disaster-occurrence construction site 17a shot by the web camera 15 is transmitted from the first personal computer 13a to the management server 14 via the Internet, and the management server 14 receives the image of the disaster-occurrence site 17a (disaster-occurrence site image first reception means).

[0098] Next, the central processing unit of the management server 14 determines the feasibility of construction work at the disaster-occurrence construction site 17a based on the disaster information (warning level) of the disaster-occurrence construction site 17a obtained by the disaster information acquisition means and the image of the disaster-occurrence site 17a obtained by the disaster-occurrence site image first reception means (construction work feasibility second determination means). For example, when the disaster level in the disaster information is warning level 5 (urgent safety assurance) or warning level 4 (evacuation instruction), it is determined that construction work at the disaster-occurrence construction site 17a is not feasible. Also, even if the disaster level in the disaster information is warning level 3 (evacuation of the elderly, etc., evacuation preparation), warning level 2 (confirmation of evacuation behavior), or warning level 1 (early warning information), if it is determined from the image of the disaster-occurrence site 17a that damage such as damage or collapse has occurred at the disaster-occurrence construction site 17a, it is determined that construction work at the disaster-occurrence construction site 17a is not feasible. Further, when the disaster level in the disaster information is warning level 3 (evacuation of the elderly, etc., evacuation preparation), warning level 2 (confirmation of evacuation behavior), or warning level 1 (early warning information), and it is determined from the image of the disaster-occurrence site 17a that no damage such as damage or collapse has occurred at the disaster-occurrence construction site 17a, it is determined that construction work at the disaster-occurrence construction site 17a is feasible.

[0099] When the disaster at the disaster-stricken site 17a is at or above the set level, the management server 14 transmits safety confirmation information to the tablet 11a held by the construction workers working at the disaster-stricken construction site 17a via the Internet (safety confirmation information transmission means). For example, when the disaster level in the disaster information is warning level 5 (urgent safety assurance) or warning level 4 (evacuation instruction), it is determined that a disaster at or above the set level has occurred, and safety confirmation information is transmitted to the tablet 11a. Further, the management server 14 transmits the disaster occurrence site image of the disaster-stricken construction site 17a received by the disaster occurrence site image first receiving means (the disaster occurrence site image of the predetermined disaster-stricken construction site 17a where the construction workers are working) to the tablet 11a via the Internet (disaster occurrence site image transmission means), and transmits the feasibility of construction work at the disaster-stricken construction site 17a determined by the second construction work feasibility determination means (construction work not feasible, construction work feasible) to the tablet 11a via the Internet (second construction work feasibility transmission means).

[0100] The tablet 11a receives the safety confirmation information and the disaster occurrence site image transmitted from the management server 14 by the safety confirmation information transmission means and the disaster occurrence site image transmission means (safety confirmation information receiving means, second disaster occurrence site image receiving means), and receives the feasibility of construction work at the disaster-stricken construction site 17a transmitted from the management server 14 by the second construction work feasibility transmission means (construction work not feasible, construction work feasible) (second construction work feasibility receiving means). When the central processing unit of the tablet 11a receives the safety confirmation information, the disaster occurrence site image, and the feasibility of construction work transmitted from the management server 14 by the safety confirmation information transmission means, the disaster occurrence site image transmission means, and the second construction work feasibility transmission means, it outputs (displays) the safety confirmation transmission screen 24 shown in FIG. 7 on the touch panel 15 (safety confirmation information output means, disaster occurrence site image output means, second construction work feasibility output means).

[0101] On the safety confirmation transmission screen 24 in Fig. 7, there are output (displayed) a construction-related person information output area 24a with the registered construction-related person's construction-related person information (name of the construction-related person, face photo of the construction-related person), a disaster-occurred construction site information output area 24b with the disaster-occurred construction site information where a disaster has occurred (name of the construction site and the planned construction site, address of the construction site and the planned construction site, seismic intensity and weather in the vicinity including the disaster-occurred construction site), a disaster-occurred site image output area 24c with the disaster-occurred site image of the disaster-occurred construction site, a construction work feasibility output area 24d with the feasibility of construction work at the disaster-occurred construction site (construction work not possible, construction work possible) output (displayed), a safety transmission button 24e, a menu screen button 24f, and an end button 24g. When the construction-related person is safe, they tap the safety transmission button 24f on the safety confirmation screen. In addition, by looking at the feasibility of the construction work output (displayed) in the construction work feasibility output area 24d, the construction-related person can know whether the construction work at the disaster-occurred construction site 17a is not possible or possible.

[0102] When the safety transmission button 24e is tapped, the central processing unit of the tablet 11a transmits the safety (safe) reply information of the construction-related person to the management server 14 together with the communication node identification information, transmission date and time, construction-related person identification information (construction-related person identifier), and disaster-occurred construction site identification information (disaster-occurred construction site identifier) (safety reply information transmission means). The management server 14 receives the safety (safe) reply information transmitted from the tablet 11a (safety reply information receiving means). The management server 14 stores (stores) the received safety reply information (including the transmission date and time) in the large-capacity virtual storage area (large-capacity storage area (or large-capacity hard disk)) in a state associated with the communication node identification information, construction-related person identification information (construction-related person identifier), and disaster-occurred construction site identification information (disaster-occurred construction site identifier) (safety reply information storage means).

[0103] When the management server 14 that has received the safety reply information outputs (displays) the safety confirmation information screen 25 shown in FIG. 8 on the display 19 (safety confirmation information output means). On the safety confirmation information screen 25 in FIG. 8, there are a disaster-occurred construction site information output area 25a that outputs (displays) disaster-occurred construction site information (name of the construction site, address of the construction site, telephone number and email address of the construction site), a disaster-occurred construction site image output area 25b that outputs (displays) an image of the disaster-occurred construction site, a safety confirmed construction-related person number output area 25c that outputs (displays) the number of each construction-related person who has received the safety reply information, and a safety confirmed construction-related person information output area 25d that outputs (displays) the construction-related person identification information (name of the construction-related person, telephone number of the construction-related person, age of the construction-related person, gender of the construction-related person, email address, face photo of the construction-related person) of each construction-related person who has received the safety reply information.

[0104] When a disaster of a set level or higher occurs at a predetermined construction site 17a by the management server 14 (management node) in the construction site information providing system 10, the management server 14 transmits safety confirmation information to the tablet 11a (communication node) held by the construction-related person working at the disaster-occurred construction site 17a. When the tablet 11a receives the safety confirmation information transmitted from the management server 14, the tablet 11a transmits the safety (security) reply information of the construction-related person holding the tablet 11a to the tablet 11a. When the management server 14 receives the safety reply information of the construction-related person from the tablet 11a by the safety reply information transmission means, the management server 14 outputs the safety reply information of the construction-related person. Therefore, it is possible to quickly confirm the safety of the construction-related persons working at the disaster-occurred construction site 17a, and appropriate life rescue can be carried out in the event of a disaster.

[0105] When the management server 14 (management node) in the construction site information providing system 10 receives the safety reply information of the construction-related person from the tablet 11a (communication node), the management server 14 outputs the safety confirmation information of the construction-related person. Therefore, managers, site supervisors, on-site supervisors, etc. among the construction-related persons can know the safety of the construction-related persons at each disaster-occurred construction site, and managers, site supervisors, on-site supervisors, etc. can accurately grasp the safety of the construction-related persons at each disaster-occurred construction site.

[0106] In the construction site information providing system 10, when a disaster occurs or immediately after a disaster occurs, the management server 14 (management node) receives a disaster occurrence site image of the construction site from the web camera 15, and among the received disaster occurrence site images of each construction site, the disaster occurrence site image of a predetermined disaster occurrence construction site 17a where construction-related personnel work is transmitted to a tablet 11a (communication node) held by the construction-related personnel. The tablet 11a receives the disaster occurrence site image of the disaster occurrence construction site 17a where the construction-related personnel work, which is transmitted from the management server 14, and outputs the received disaster occurrence site image of the predetermined disaster occurrence construction site 17a. Therefore, it is possible to notify the construction-related personnel of the presence or absence of a disaster, the construction-related personnel can know the damage situation and safety of the construction site 17a due to the disaster, the construction-related personnel can evacuate safely and quickly from the disaster occurrence site 17a, and the safety of the construction-related personnel at the disaster occurrence site 17a can be ensured.

[0107] Based on the disaster information (warning level) received by the management server 14 (management node) and the disaster occurrence construction site image of the construction site 17a, the construction site information providing system 10 determines whether construction work can be carried out at the construction site 17a. The determination result of whether construction work can be carried out at the construction site 17a is transmitted to a tablet 11a (communication node) held by the construction-related personnel. The tablet 11a receives the determination result of whether construction work can be carried out at the construction site 17a, which is transmitted from the management server 14, and outputs the received determination result of whether construction work can be carried out at the construction site 17a. Therefore, based on the determination of whether construction work can be carried out by the management server 14, it is possible to decide whether work can be carried out at the construction site 17a after a disaster occurs, avoid the risk of determining whether work can be carried out based on the personal judgment of the construction-related personnel, and ensure the safety of the construction-related personnel's work at the disaster occurrence site 17a.

[0108] FIG. 9 is a diagram showing an example of a vibration information output screen 26 output (displayed) on the touch panel 15 of the tablet 11. In FIG. 9, the display of each data output to each output area is omitted. Hereinafter, it is assumed that vibrations equal to or higher than the set level (alarm level) occur at the first construction site 17a. The vibration information (vibration value) of those construction sites measured by the vibration sensor is transmitted from the first to third personal computers 13a to 13b to the management server 14. The management server 14 that has received the vibration information compares the set level (alarm level) of the vibration information stored in advance with the received vibration information, and determines whether the received vibration information is equal to or higher than the set level (alarm level) of the stored vibration information (vibration information comparison means). For example, when the set level (alarm level) of the vibration information (vibration value) is seismic intensity 3 (75 decibels) or seismic intensity 4 (85 decibels) or weak seismic intensity 5 (95 decibels), and the received vibration information (vibration value) is equal to or higher than that set level (alarm level), it is determined that vibrations at the alarm level have occurred.

[0109] When the management server 14 determines, as a result of comparing the set level (alarm level) of the vibration information (vibration value) stored by the vibration information comparison means with the received vibration information (vibration value), that the received vibration information is equal to or higher than the set level (alarm level) of the stored vibration information (when vibrations equal to or higher than the set level (alarm level) occur), the management server 14 transmits, via the Internet, a photographing instruction signal for the construction site image at the time of vibration occurrence at the first construction site 17a where vibrations equal to or higher than the set level (alarm level) have occurred to the first personal computer 13a (the personal computer 13a installed at the construction site 17a where vibrations have occurred among the first to third personal computers 13a to 13b) (construction site photographing instruction means).

[0110] Upon receiving a shooting instruction signal, the central processing unit of the first personal computer 13a takes a picture of the construction site image of the first construction site 17a when vibration equal to or higher than the set level (warning level or higher) occurs, and stores the construction site image (image data) taken by the web camera 15 together with a predetermined hash value in a large-capacity storage area (or large-capacity hard disk) (block). The central processing unit of the first personal computer 13a transmits the construction site image (image data) when vibration equal to or higher than the set level (warning level or higher) occurs, together with a predetermined hash value, to the management server 14 via the Internet.

[0111] The management server 14 receives the construction site image (image data) when vibration equal to or higher than the set level (warning level or higher) is transmitted from the first personal computer 13a, and stores (stores) the vibration value (decibel) equal to or higher than the set level (warning level or higher), the construction site image (image data) when vibration equal to or higher than the set level (warning level or higher) occurs, and the transmission date and time in a large-capacity virtual storage area (large-capacity storage area (or large-capacity hard disk)) in a state associated with the construction site specific information (construction site specific identifier) together with the hash value (vibration information storage means equal to or higher than the set level).

[0112] Since the vibration value (decibel) equal to or higher than the set level (warning level or higher) and the construction site image (image data) when vibration equal to or higher than the set level (warning level or higher) occurs are stored in the large-capacity virtual storage area (block) of the management server 14 as transaction data, an accurate history of the vibration value (decibel) equal to or higher than the set level (warning level or higher) and the construction site image (image data) when vibration equal to or higher than the set level (warning level or higher) occurs is saved.

[0113] The management server 14 transmits, via the Internet, vibration information at or above the set level (vibration value (decibel) at or above the set level (warning level or above), construction site image (image data) at the time of vibration occurrence at or above the set level (warning level or above)) that occurred at the first construction site 17a where construction workers working at the first construction site 17a where vibrations at or above the set level occurred hold the tablet 11a (vibration information transmission means). The central processing unit of the tablet 11a receives the vibration information at or above the set level of the first construction site 17a transmitted from the management server 14 by the vibration information transmission means (vibration information reception means). The central processing unit of the tablet 11a outputs the vibration information of a predetermined construction site 17a received by the vibration information reception means (vibration information output means).

[0114] On the touch panel 15 of the tablet 11a, a vibration information output screen 26 shown in FIG. 9 is output (displayed) (vibration information output means). On the vibration information output screen 26 of FIG. 9, a construction site information output area 26a that outputs (displays) construction site information (name of the construction site, address of the construction site, vibration occurrence date and time), a vibration value output area 26b that outputs (displays) a vibration value (decibel) at or above the set level (warning level or above), a construction site image output area 26c that outputs (displays) a construction site image (image data) of the first construction site 17a at the time of vibration occurrence at or above the set level (warning level or above), a warning message output area 26d that outputs (displays) a warning message (vibration warning information) indicating that the vibration has exceeded the set level (warning level), a menu screen button 26e, and an end button 26f are output (displayed).

[0115] When the vibration level (alarm level) of the vibration transmitted from the vibration sensor exceeds the set level in the construction site information providing system 10, the management server 14 (management node) transmits the vibration information (vibration value (decibel) above the set level (above the alarm level), construction site image (image data) at the time of vibration occurrence above the set level (above the alarm level)) to the tablet 11a (communication node) held by the construction worker working at the first construction site 17a where the vibration above the set level has occurred. The tablet 11a receives the vibration information of the construction site 17a where the construction worker is working transmitted from the management server 14, and outputs the received vibration information of the construction site 17a (vibration value (decibel) above the set level (above the alarm level), construction site image (image data) at the time of vibration occurrence above the set level (above the alarm level)) and the alarm message (vibration alarm information). Therefore, the construction worker working at a predetermined construction site 17a can know the abnormality due to the vibration of the construction site 17a based on the vibration information, and the construction worker who has detected the danger can safely and quickly evacuate from the construction site 17a, and the safety of the construction worker can be ensured.

[0116] FIG. 10 is a diagram showing an example of a sound (noise) information output screen 27 output (displayed) on the touch panel 15 of the tablet 11. In FIG. 10, the display of each data output to each output area is omitted. Hereinafter, it is assumed that a sound above the set level (noise level) has occurred at the first construction site 17a. The sound information (noise value) of those construction sites measured by the microphone 16 is transmitted from the first to third personal computers 13a to 13b to the management server 14. The management server 14 that has received the sound information compares the set level (noise level) of the sound information stored in advance with the received sound information, and determines whether the received sound information is equal to or higher than the set level (noise level) of the stored sound information (sound information comparison means). For example, when the set level (noise level) of the sound information (noise value) is 70 decibels or 80 decibels or 90 decibels, and the received sound information (noise value) is equal to or higher than the set level (noise level), it is determined that a sound at the noise level has occurred.

[0117] When the management server 14 compares the set level (alarm level) of the sound information (noise value) stored by the sound information comparison means with the received sound information (noise value) and determines that the received sound information is equal to or higher than the set level (alarm level) of the stored sound information (when sound (noise) equal to or higher than the set level (alarm level) occurs), the management server 14 transmits, via the Internet, a shooting instruction signal for a construction site image at the time of sound (noise) generation at the first construction site 17a where sound equal to or higher than the set level (alarm level) has occurred, to the first personal computer 13a (the personal computer 13a installed at the construction site 17a where sound (noise) has occurred among the first to third personal computers 13a to 13b) (construction site shooting instruction means).

[0118] The central processing unit of the first personal computer 13a that has received the shooting instruction signal takes a picture of the construction site image of the first construction site 17a at the time of sound (noise) generation where sound equal to or higher than the set level (alarm level) has occurred by the web camera 15, and stores the construction site image (image data) taken by the web camera 15 in a large-capacity storage area (or large-capacity hard disk) (block) together with a predetermined hash value. The central processing unit of the first personal computer 13a transmits, via the Internet, the construction site image (image data) at the time of sound (noise) generation equal to or higher than the set level (alarm level) to the management server 14 together with a predetermined hash value.

[0119] The management server 14 receives the construction site image (image data) at the time of sound (noise) generation equal to or higher than the set level (alarm level) transmitted from the first personal computer 13a, and stores (stores) in a large-capacity virtual storage area (large-capacity storage area (or large-capacity hard disk)) in a state where the sound value (decibel) equal to or higher than the set level (alarm level), the construction site image (image data) at the time of sound (noise) generation equal to or higher than the set level (alarm level), and the transmission date and time are associated with the construction site specific information (construction site specific identifier) together with the hash value (sound information storage means equal to or higher than the set level).

[0120] Since the sound value (decibel) equal to or higher than the set level (warning level) and the construction site image (image data) at the time of sound (noise) generation equal to or higher than the set level (warning level) are stored as transaction data in the large-capacity virtual storage area (block) of the management server 14, an accurate history of the sound value (decibel) equal to or higher than the set level (warning level) and the construction site image (image data) at the time of sound (noise) generation equal to or higher than the set level (warning level) is preserved.

[0121] The management server 14 transmits (sound information transmission means) the sound (noise) information (sound value (decibel) equal to or higher than the set level (warning level), construction site image (image data) at the time of sound (noise) generation equal to or higher than the set level (warning level)) at the first construction site 17a where the sound (noise) equal to or higher than the set level has occurred to the tablet 11a held by the construction-related person working at the first construction site 17a via the Internet. The central processing unit of the tablet 11a receives (sound information receiving means) the sound (noise) information equal to or higher than the set level at the first construction site 17a (sound information equal to or higher than the set level (warning level) at the construction site 17a where the construction-related person works) transmitted from the management server 14 by the sound information transmission means. The central processing unit of the tablet 11a outputs (sound information output means) the sound (noise) information of a predetermined construction site 17a received by the sound information receiving means.
