Description

  The present invention relates to a construction site communication system in which communication is performed to a construction site when a disaster occurs.

  The construction site is a place where construction work such as construction and civil engineering is performed, and a building such as a building is constructed in this place. Equipment such as temporary materials, materials and construction equipment necessary for constructing a building is placed at the construction site, and an operator creates a building using these equipment.

  When a building is under construction, the building still does not have the disaster prevention performance that should be possessed after completion. In addition, the above-mentioned construction site equipment is not fully equipped with disaster countermeasures. When a disaster occurs at a construction site in such an environment, it is difficult to ensure the safety of workers. In a normal building, there is an example of securing human safety using a communication system for communicating disaster information in addition to the disaster prevention performance of the building itself when a disaster occurs.

  In Patent Document 1 below, an elevator in a building and a maintenance center that remotely monitors and maintains the elevator are connected by a public telephone network, and the maintenance center and seismic detectors provided in each place are public telephones. A communication system connected by a network is described. In this communication system, when an earthquake occurs, information on each earthquake detector is sent to the maintenance center via the telephone line network, and a command for restricting the operation of the elevator based on the information is sent from the maintenance center via the public telephone network. Sent to the elevator. It is shown that the safety of passengers is ensured because the elevator automatically stops at the nearest floor by the sent command.

  In general, the degree of shaking of a building due to seismic waves is affected by the regional characteristics of the building, such as the properties of the ground and the groundwater level. The seismic wave includes a P wave (longitudinal wave) that is transmitted by moving a volume change of a medium (a substance that transmits the wave) and an S wave (transverse wave) that is transmitted by deformation (twist) of the medium. When an earthquake occurs, the P wave and S wave of the seismic wave are generated simultaneously. For example, when traveling through the crust, the moving speed of the P wave is approximately 1.7 times faster than the moving speed of the S wave. The length of time from the initial fine movement due to the arrival of the P wave to the main movement due to the arrival of the S wave is referred to as the initial fine movement duration (or SP time). Theoretically, the initial tremor duration will increase as the distance to the epicenter increases. Among the seismic waves, the speed at which the P wave propagates in the vicinity of the ground surface is about 6 to 7 km / second, and the speed at which the S wave propagates through the crust is about 3.5 to 4 km / second. Therefore, for example, at a distance of 12 km, a time difference of about 2 seconds occurs in the P wave, and a time difference of about 3 seconds occurs in the S wave.

  In the communication system of Patent Document 1, communication is performed via a public telephone network using a circuit switching system. The public telephone network is, for example, a PSTN (Public Switched Telephone Network), and generally takes the form of using a service provided by a telecommunications carrier. In the circuit switching method, since communication is normally started after a communication path from a transmission source to a transmission destination is secured in advance, when data communication is performed, it takes several seconds to several tens of seconds to start data communication. That is, information cannot be communicated quickly. Also, when a disaster occurs, the public telephone network may not be able to communicate reliably due to communication restrictions by a telecommunications carrier or interruption of the communication line due to disconnection of a cable or the like of the public telephone network.

  In addition, when the communication system disclosed in Patent Document 1 is introduced to a construction site, a procedure must be performed for a telecommunications carrier in order to newly use a public telephone network. Also, if a new public telephone network line is laid, it will take time to open. Furthermore, at a construction site where renovation work is performed in a normal building, it is not easy to lay a new public telephone line in the building.

  An object of the present invention is a construction site at the time of a disaster that can be easily introduced into a construction site, can reliably transmit disaster information to the construction site, and can communicate quickly when a disaster occurs. It is to provide a communication system.

  The construction site communication system in the event of a disaster according to the present invention is connected to a facility management device that manages the state of facilities in a building, and the facility management device via a storage and exchange communication channel, and remotely connects the facilities in each building. A monitoring center for monitoring, and a communication device that is provided at a construction site and communicates with the monitoring center and the facility management device, wherein the communication device and the facility management device are wirelessly stored and exchanged. Connected via a communication path, the monitoring center has disaster information acquisition means for acquiring information related to a disaster, and when a disaster occurs, the monitoring center performs a disaster based on the disaster information acquired by the disaster information acquisition means. A standby command is transmitted to the communication device via the facility management device.

In addition, the facility management device is a building in each region, and when a disaster occurs, a specific facility management device provided in a specific building that is determined to be a base in the region to which the building belongs A general facility management device provided in a building in the area, and the specific facility management device and the monitoring center are connected by a storage and exchange type communication path, and the specific facility management device, When the general equipment management device in the area to which the specific equipment management device belongs and the communication device in the area are connected by a wireless storage and exchange type communication path and a disaster occurs, the monitoring center identifies the specific equipment management device. The disaster standby command can be transmitted to the communication device via the facility management device.

  In addition, the specific facility management device has a function of the monitoring center, and the specific facility management devices in each region are connected to each other via a wireless storage-and-exchange communication path, and the monitoring center functions in the event of a disaster. Otherwise, the specific facility management device becomes a monitoring center in each region, and the specific facility management device can transmit a disaster standby command to the communication device in the region to which the specific facility management device belongs.

  Further, the communication device is connected to the communication device and has a photographing unit for photographing a predetermined place on the construction site, and the communication device can transmit image information photographed by the photographing unit to the monitoring center.

  The disaster information acquisition means acquires information related to the occurrence of an earthquake, and when an earthquake occurs, the monitoring center directs an earthquake standby command to the communication device based on the earthquake information acquired by the disaster information acquisition means. You can make a call.

  The building having the facility management apparatus is provided with an earthquake detector for detecting an earthquake, and the disaster information acquisition means can acquire the earthquake information detected by the earthquake detector.

  The monitoring center has arrival time calculation means for calculating the arrival time of the seismic wave in each region based on earthquake information, and the monitoring of the earthquake standby command including the arrival time calculated by the arrival time calculation means The center can make a call to the communication device.

  The arrival time calculating means can calculate the arrival time of the seismic wave in each area based on the information on the P wave of the seismic wave among the earthquake information.

  In addition, the monitoring center has prediction means for predicting the degree of shaking of the building in each region based on earthquake intensity information among earthquake information, and the prediction value by the prediction means is a predetermined value or more The monitoring center can transmit an earthquake standby command to the communication device.

  With the above configuration, the construction site communication system in the event of a disaster enables the monitoring center that acquired the disaster information to remotely send a disaster standby command to the construction site communication device via the equipment management device. Become. Since the monitoring center, the facility management device, and the communication device are connected via a communication path based on the storage and exchange method, the time until the start of communication is shortened, and rapid information communication is possible when a disaster occurs. In addition, by using a communication path based on the storage and exchange method, even if a disaster occurs, communication can be reliably performed without being affected by the communication regulation by the telecommunications carrier. Further, by using a wireless storage and exchange type communication path, even if a disaster occurs, communication can be reliably performed without being affected by disconnection of the communication circuit due to disconnection. Furthermore, by using a wireless storage and exchange type communication path, a communication system can be easily introduced to a construction site simply by installing a communication device connected to the communication path.

  As described above, according to the construction site communication system at the time of disaster occurrence of the present invention, it can be easily introduced into the construction site, and when disaster occurs, disaster information is reliably transmitted to the construction site, And it can communicate quickly.

  Hereinafter, an embodiment of a construction site communication system when a disaster according to the present invention occurs will be described with reference to the drawings. FIG. 1 is a diagram showing a schematic configuration of a communication network 12 of a construction site communication system 10 when a disaster occurs according to the present embodiment.

  The construction site communication system 10 in the event of a disaster includes a monitoring center 14 that remotely monitors facilities in a wide group of buildings, and a communication network 12 that is constructed so that facility information of each building is aggregated in the monitoring center 14. Have.

  The communication network 12 is constructed by dividing a wide-area building group into a plurality of areas 36. The buildings in each region 36 are buildings connected to the communication network 12, and are classified into two types: a specific building 16 specified for each region 36 and a general building 18 that is a building other than the specific building 16. . In the present embodiment, the area 36 is divided into, for example, an area A 36 a and an area B 36 b, and buildings in each area 36 are classified into two types, a specific building 16 and a general building 18. The specific building 16 is a building that serves as a base in the area 36 to which the specific building 16 belongs when a disaster occurs. Therefore, among the buildings in the area 36, a building having high earthquake resistance performance, wind resistance performance, or fire resistance performance at the time of disaster is desirable. Note that the range indicated by the wide area is a range including a plurality of buildings connected to the communication network 12, whether it represents the whole of Japan or a certain region, for example, the Kanto region, For example, it may represent Tokyo. Further, the range of the area 36 is an area that can be communicated without problems by the wireless connection network 26 described later, and is determined by the density of buildings in the area 36.

  The monitoring center 14 and each specific building 16 are connected by a storage / switching network 24 which is a communication path using a storage / switching system. In addition, the specific building 16 and each general building 18 in the area 36 to which the specific building 16 belongs are connected by a wireless connection network 26 using a storage and exchange system. With such a configuration, communication is performed between the monitoring center 14 and the specific building 16 for each area 36, and communication is performed between each specific building 16 and the general building 18 in the area 36 to which the specific building 16 belongs. That is, a hierarchical communication network 12 such as a monitoring center 14, a specific building 16, and a general building 18 is constructed, and communication is performed.

  The communication network 12 is also constructed by dividing the construction site 28 into a plurality of regions 36. The construction site 28 is a place where construction work is performed, and the construction work includes new construction work, dismantling work, repair work, and the like. The construction site 28 and the specific and general buildings 16 and 18 in the area 36 to which the construction site 28 belongs are connected to the wireless connection network 26. With this configuration, communication with the construction site 28 and communication with the general buildings 16, 18 is performed, and also between the construction site 28 and the monitoring center 14 via these buildings 16, 18. Communication takes place.

  The storage and exchange method used for the communication network 12 is also called an IP packet exchange method, and communication data is divided into units called packets for communication. Since the storage and exchange system does not monopolize the line for a certain period of time, the line can be used efficiently. In a communication path using the circuit switching method, when data communication is performed, it takes several seconds to several tens of seconds to start data communication. On the other hand, in a communication path using the storage and exchange method, data communication can be started and communicated in less than approximately one second. In addition, in the case of a large-scale disaster, a communication path using a circuit switching method may be subjected to communication regulation by a telecommunications carrier. On the other hand, since the communication path by the storage and exchange method does not occupy a line, such communication restriction is not normally performed. Therefore, the construction network communication system 10 at the time of a disaster can reliably transmit information and communicate quickly by using the communication path of the storage and exchange method by the communication network 12. .

  Next, the configuration of the construction site communication system 10 when a disaster occurs will be described with reference to FIG. FIG. 2 is a diagram showing a schematic configuration of the construction site communication system 10 when a disaster occurs according to the present embodiment. As an example, the area A36a shown in FIG. 1 will be described, and a system in which the monitoring center communicates with the construction site 28 in the area A36a when a disaster occurs will be described. Note that the present invention is not limited to when a disaster occurs, but can also be applied to a communication system in a normal construction site. Disasters include, for example, earthquakes, strong winds caused by typhoons, fires, and the like.

  The communication network 12 of the construction site communication system 10 at the time of a disaster is connected to a monitoring center 14, a communication device 30 provided at the construction site 28, and a facility management device that manages the state of the facility 34 in the building. Yes. The facility management apparatus is classified into two types: a specific facility management apparatus 20 installed in the specific building 16 and a general facility management apparatus 22 installed in the general building 18. The equipment 34 in the building is not limited to equipment provided strictly in the space inside the building, but includes equipment related to the building. The facility 34 is, for example, a transport facility such as an elevator, an air conditioning facility, a water supply / drainage sanitary facility, or a lighting facility.

  The monitoring center 14 and the specific and general facility management apparatuses 20 and 22 have transmission / reception means 38 for transmitting and receiving data. The data includes facility information indicating the state of the facility, an abnormality, a failure, and the like, and information related to a disaster described later. The transmission / reception means 38 of the specific facility management apparatus 20 includes a router 40 corresponding to the storage / switching network 24 and a wireless router 42 corresponding to the wireless connection network 26. The transmission / reception means 38 of the general facility management apparatus 22 has a wireless router 42 corresponding to the wireless connection network 26. The transmission / reception means 38 are connected by a communication path based on a storage and exchange system. That is, the transmission / reception means 38 of the monitoring center 14 and the router 40 of the specific facility management device 20 are connected by the storage and switching network 24, and the wireless router 42 of the specific facility management device 20 and the wireless of the general facility management device 22 are connected. The router 42 is connected by the wireless connection network 26. The communication device 30 includes a wireless router 42 corresponding to the wireless connection network 26, and the wireless router 42 is connected to the wireless router 42 of the specific and general facility management devices 20 and 22 through the wireless connection network 26. The Thereby, the monitoring center 14, the specific and general equipment management apparatuses 20 and 22, and the communication apparatus 30 can transmit and receive data to and from each other.

  In the specific and general buildings 16 and 18, an earthquake detector 32 for detecting an earthquake is arranged. The earthquake sensor 32 outputs the sensed signal to a specific facility management device 20 or 22 for the building where the earthquake sensor 32 is located. When the earthquake detector 32 arranged in the general building 16 detects an earthquake, a signal indicating the earthquake is transmitted to the general facility management device 22. The general equipment management device 22 transmits information related to the occurrence of the earthquake (hereinafter referred to as earthquake information) to the specific equipment management device 20 via the wireless connection network 26. The transmitted specific facility management apparatus 20 transmits the earthquake information to the monitoring center 14 via the storage / switching network 24. On the other hand, when the earthquake detector 32 disposed in the specific building 16 detects an earthquake, a signal indicating the earthquake is transmitted to the specific facility management device 20, and the specific facility management device 20 stores and exchanges the earthquake information. The data is transmitted to the monitoring center 14 via the network 24. The earthquake information refers to information such as information on an assumed epicenter, arrival times of seismic waves (P waves and S waves), earthquake strength, and the like.

  The monitoring center 14 includes a disaster information acquisition unit 52 that acquires information related to a disaster, and a determination unit 46 that determines transmission of a disaster standby command based on the acquired information. The information on the disaster is, for example, earthquake information, and the disaster information acquisition unit 52 acquires the earthquake information transmitted from the earthquake detector 32 regarding the specific and general facility management devices 20 and 22. The information on the disaster acquired by the disaster information acquisition means 52 is not limited to the earthquake information from the earthquake detector 32, but is information on weather such as earthquakes, fires and typhoons from other information providing organizations (not shown). Also good. The disaster standby command is a command transmitted to the communication device 30 in order to ensure the safety of the worker on the construction site 28, and recommends the worker to stop working, wait or evacuate. When the disaster is an earthquake, the monitoring center 14 transmits a disaster standby command (hereinafter referred to as an earthquake standby command) including earthquake information such as the strength of the earthquake or the arrival time of the earthquake wave to the communication device 30. By the earthquake standby command, it is possible to prepare for the earthquake in advance at the construction site 28, and the safety of the worker can be ensured.

  The determination means 46 calculates the arrival time of the earthquake wave in each area 36 based on the earthquake information, and predicts the degree of shaking of the building in each area 36 based on the strength of the earthquake in the earthquake information. And a prediction means 50.

  The arrival time calculation means 48 calculates the arrival time of the seismic wave in each region 36 based on the information on the P wave of the seismic wave among the earthquake information. There are two types of seismic waves, S waves and P waves, having different propagation speeds as described above. The arrival time of the seismic wave can be calculated using the speed difference between the two types of waves. Hereinafter, it explains in full detail using a figure. FIG. 3 is a diagram illustrating the principle of the time difference until the seismic wave (P wave and S wave) that has reached the region X36x reaches the region Y36y and the region Z36z. Here, a description will be given using a model that assumes that the region X36x, the region Y36y, and the region Z36z are linearly arranged in the direction in which the seismic wave is transmitted.

  First, the time of the seismic wave that reaches the region X36x will be described. If the time when the seismic wave reaches the building in the region X36x and the seismic detector 32 disposed in the building senses the P wave among the seismic waves is Tpx, the time Tsx for sensing the S wave is Tpx + α. This time α is the initial tremor duration (or SP time). Theoretically, if the distance to the epicenter is increased, the initial tremor duration becomes longer. Therefore, by measuring this time α, the distance to the epicenter can be estimated to some extent.

  Next, the time when the seismic wave that reaches the region X36x reaches the region Y36y and the region Z36z will be described. A building in the region X36x and a building in the region Y36y are separated by a distance X, and a building in the region X36x and a building in the region Z36z are separated by a distance Y. The time Tpa when the P wave reaches the position of the building in the area Y36y is represented by Tpx + β1, and the time Tpb when the P wave reaches the building position in the area Z36z is represented by Tpx + γ1. The times β1 and γ1 are values obtained by multiplying the speed at which the P wave propagates near the ground surface by the distances X and Y. On the other hand, the time Tsa at which the S wave reaches the position of the building in the area Y36y is represented by Tpx + α + β2, and the time Tsb at which the S wave reaches the position of the building in the area Z36z is represented by Tpx + α + γ2. Times β2 and γ2 are values obtained by multiplying the speed at which the S wave propagates near the ground surface by the distances X and Y. As described above, the speed at which the P wave propagates near the ground surface is about 6 to 7 km / second, and the speed at which the S wave propagates through the crust is about 3.5 to 4 km / second. As described above, after the earthquake detector 32 detects that the earthquake wave has reached the region X36x close to the epicenter, the arrival time of the earthquake wave in the region Y36y and the region Z36z is calculated based on the earthquake information from the earthquake detector 32. It is clear that it can be calculated. However, seismic waves actually propagate on the ground plane. Therefore, by applying the above principle, arrival times to other areas are calculated based on earthquake information from a plurality of points.

  The determination means 46 stores in advance map information such as the position of each region 36, the specific and general buildings 16 and 18, and the position of the construction site 28. When a building detects earthquake information, the determination unit 46 calculates the distance from the building to the construction site 28 based on the map information. The arrival time calculation means 48 calculates the time for the P wave and S wave of the seismic wave to reach the construction site 28 from the distance and the time when the P wave arrives at the building where the earthquake information is detected. This arrival time is transmitted from the monitoring center 14 to the construction site 28 as an earthquake standby command.

  The monitoring center 14 has display means 54 for displaying the status of the construction site 28 photographed by the photographing means 56 described later. The display means 54 is a monitor, for example.

  The specific facility management apparatus 20 has a function of transmitting a disaster standby command to the construction site 28 based on the disaster information when a disaster occurs. That is, similarly to the monitoring center 14, it has disaster information acquisition means 52, determination means 46, and display means 54. In addition, since the disaster information acquisition unit 52 of the specific facility management apparatus 20 acquires the disaster information, the specific facility management apparatuses 20 in each region 36 are connected to each other via a wireless storage and exchange communication path. As a result, even when the monitoring center 14 becomes malfunctioning when a disaster occurs, the specific facility management device 20 is connected to the communication device 30 in the area 36 to which the specific facility management device 20 belongs based on the acquired disaster information. A disaster standby command can be sent.

  The communication device 30 at the construction site 28 is connected with an imaging unit 56 for imaging the situation inside the construction site 28. The photographing means 56 is, for example, a video camera, and is provided at a predetermined place such as a work place or an equipment place in the construction site 28. Image information captured by the imaging unit 56 is transmitted to the specific facility management apparatus 20 and the monitoring center 14 via the communication apparatus 30. From the images displayed on the display means 54 of the specific facility management apparatus 20 and the monitoring center 14, it is possible to grasp the damage situation of the construction site 28, which can be used for preventing theft of equipment and the like.

  Next, the operation of the construction site communication system 10 when a disaster occurs will be described. As an example, an earthquake standby command transmitted from the monitoring center 14 to the construction site 28 in the area A 36a when an earthquake occurs is taken, and the construction site at the time of disaster occurrence in which communication of this earthquake standby command is performed. An operation of the communication system 10 will be described.

  When an earthquake occurs and the earthquake detector 32 arranged in, for example, the general building 18 in a certain area 36 detects the earthquake, the earthquake information is received from the general facility management device 22 of the general building 18 via the wireless switching network 26. Is transmitted to a specific facility management apparatus 20. Then, the earthquake information transmitted to the specific facility management apparatus 20 is transmitted to the monitoring center 14 via the storage / switching network 24. The earthquake information is acquired and aggregated by the disaster information acquisition means 52 together with earthquake information of other buildings or information providing organizations. The aggregated earthquake information enables the monitoring center 14 to respond according to regional characteristics. In the case of an earthquake, the degree of shaking varies depending on regional characteristics, such as ground and groundwater levels. Therefore, it is possible to transmit an accurate earthquake standby command by collecting and sharing the earthquake information of the area 36 that receives substantially the same earthquake motion.

  In the determination means 46, the arrival time calculation means 48 calculates the arrival time of the seismic wave in the area A36a based on the aggregated earthquake information, and the prediction means 50 calculates the building information in the area A36a based on the strength of the earthquake in the earthquake information. Predict the degree of shaking. When the predicted value predicted by the predicting unit 50 is equal to or greater than a predetermined value set in advance, the determining unit 46 determines that an earthquake standby command is transmitted in the area A36a. On the other hand, when the predicted value is less than a predetermined value set in advance, it is determined that the earthquake standby command is not transmitted.

  The monitoring center 14 transmits an earthquake standby command to the communication device 30 of the construction site 28 in the area A36a. The transmitted earthquake standby command is transmitted to the specific facility management apparatus 20 via the storage and exchange network 24. Then, the earthquake information transmitted to the specific facility management device 20 is transmitted to the communication device 30 via the wireless switching network 26. The earthquake standby command transmitted to the communication device 30 is notified to the worker. The notifying means includes a method of verbally informing the contents of the earthquake standby command, and a method of notifying by voice or alarm using an alarm (not shown) such as a loudspeaker connected to the communication device 30. By the earthquake standby command, the worker can prepare for the earthquake in advance, so that the safety of the worker is ensured.

  Also, image information captured by the imaging means 56 provided at the construction site 28 is transmitted from the communication device 30 to the monitoring center 14 via the specific facility management device 20. Based on the image information transmitted to the monitoring center 14, the damage status of the construction site 28 is grasped. In addition, since the image information can remotely monitor equipment and the like, it is possible to prevent them from being stolen. In addition, the monitoring center 14 may dispatch maintenance personnel having skills capable of dealing with the failure of the equipment in the construction site 28 as needed, based on the damage situation of the construction site 28, and aim for early restoration of the equipment. it can.

  According to the construction site communication system 10 at the time of occurrence of a disaster according to the present embodiment, when a disaster occurs, communication is performed via a communication path based on a storage and exchange system, so data communication is started in less than approximately one second. It is possible to communicate and to communicate quickly. In addition, when a disaster occurs, communication is performed via a communication path using the storage and exchange method, so that communication can be performed reliably without being affected by communication restrictions by the telecommunications carrier or blocking of the communication line. it can. In addition, since communication is performed between the communication device 30 and the specific and general facility management devices 20 and 22 via a wireless storage and exchange type communication path, even if a disaster occurs, the communication circuit is interrupted by disconnection. It is possible to communicate reliably without being affected by the above. Therefore, when a disaster occurs, the disaster information can be reliably transmitted to the construction site 28 and communicated promptly.

  In addition, according to the construction site communication system 10 at the time of occurrence of a disaster according to the present embodiment, if the communication device 30 is installed, communication is performed via the wireless connection network 26. However, it can be easily introduced without laying lines.

  In the above-described embodiment, the case where the specific and general facility management devices 20 and 22 have the function of managing the state of the facility and the function of performing data communication has been described. However, the present invention is not limited to this configuration. Devices having these functions separately may be provided in the specific and general buildings 16 and 18.

  In the above embodiment, the case where the communication network 12 is constructed in a hierarchy such as the monitoring center 14, the specific building 16, and the general building 18 has been described, but there may be more layers. For example, the area 36 may be further divided into a plurality of areas, and specific and general buildings 16 and 18 and a construction site 28 may be provided for each area. According to such a hierarchical communication network 12, the function of the monitoring center 14 can be provided to either the monitoring center 14, a specific facility management device 20 in the area 36, or a specific facility management device 20 in the area. Therefore, even when the monitoring center 14 malfunctions due to a disaster, a disaster standby command is reliably transmitted to the communication device 30.

It is a figure which shows schematic structure of the construction site communication system at the time of the disaster occurrence which concerns on this embodiment. It is a figure which shows the principle about the time difference until the seismic wave (P wave and S wave) which reached the area X arrives at the area Y and the area Z.
