Description

[0001] NETWORK SYSTEM FOR RISK REMOTE MONITORING AND MANAGING OF TUNNEL UNDER CONSTRUCTION [0002]

The present invention relates to an all-in-one system for selectively and reliably collecting data necessary for remote risk (risk) monitoring management in a tunnel, which is a bad condition in a communication environment, and for multi-step relaying to a ground tunnel entrance, And to a network system for monitoring tunnel remote risk monitoring during construction in order to meet the requirements of various remote monitoring management programs for tunnels in middleware.

Tunnel construction method using tunnel boring machine (TBM) is a method of mechanizing and automating all tunnel construction processes from tunnel excavation to structure construction and burk discharge. It is an eco-friendly method with little harm to surrounding environment due to noise vibration compared with blasting method In addition to being evaluated, it is possible to perform high speed construction by continuously performing excavation, buckle removal, and support work, to form a tunnel with a mechanically stable circular structure, minimize ground deformation, and secure safety by reducing fallout.

Thus, the TBM method is advantageous for construction of a long tunnel, and is also widely used as a method for excavating an underwater tunnel.

However, the collapse of the excavation surface may occur during the construction of the tunnel due to the appearance of an unexpected fault zone in front of the excavation surface (or closure) and the removal of the rock in the reinforced area. Therefore, during the construction of the tunnel, it is necessary to probe the excavation front to detect the dangerous elements in advance and establish countermeasures. For this purpose, the excavation surface forward prediction system is used.

The excavation surface forward prediction system includes electrical resistivity survey method, advanced horizontal drilling method, and seismic survey method.

In this way, TBM and excavation surface forward prediction system are operated and many attached equipments, materials, manpower, etc. are inserted in the tunnel in excavation construction. Therefore, it is difficult to practically manage the on-site monitoring in real time. It is also difficult to establish a communication network.

Accordingly, the applicant of the present invention has developed a submarine tunnel routing system that reliably relays transmission from the TBM and the excavation surface forward prediction system to the entrance of the tunnel after receiving the tunnel management data, and has also been patented in the registered patent No. 10-1646969.

However, in general, the excavation progress data provided by the TBM reaches 198 items, and this excavation progress status data is collectively provided. Even if the excavation surface forward prediction system is installed in the TBM, it operates separately from the TBM controller, It is difficult to selectively collect data for management. Accordingly, even though the submarine tunnel routing system invented by the applicant of the present invention is utilized for real-time remote monitoring, the amount of data is increased more than necessary even if the data is stably secured.

In addition, the management program used in the all-in-one system that is operated to remotely monitor and control the construction process of the tunnels is continuously upgraded for various and complicated and better monitoring management, The complexity of the management program is further increased, and the operation of the management program is not smooth.

On the other hand, Japanese Patent No. 10-1671209 discloses a system for remotely monitoring the tunnel construction site. However, the remote monitoring is for the safety management of the worker, and it uses the location of the worker, the equipment information used by the worker, and the work environment information So that safety management is carried out based on the operator. In other words, it is difficult to predict the excavation front and apply it to the remote monitoring of the tunnel construction process while excavating with complicated equipment. In addition, it is not applicable to a remote monitoring system that acquires various information, transmits it to a remote place stably and efficiently, and efficiently utilizes various information.

Thus, in addition to stably performing intra-tunnel relay communication with the undersea tunnel routing system disclosed by the applicant of the present invention, tunnel management data necessary for remote monitoring management is collected from the TBM and excavation surface forward forecasting system, It is necessary to provide an all-in-one system and an environment that can be effectively and efficiently used in an all-in-one system.

The data collection system 100 includes a data logger 110 and an excavation surface forward prediction system (not shown) that are connected to the TBM controller 11 of the TBM 10 to obtain excavation progress data indicating the operation status of the TBM 10 And an automation module 120 connected to the automation module 120 and the data logger 110 to acquire excavation surface data detected by the excavation surface forward prediction system 20, So that the excavation surface data acquired by the automation module 120 can be collected in the data logger 110.

The excavation surface forward prediction system 20 determines the geological characteristics of the excavated surface (excavated surface or clogged surface 2) in the course of tunnel construction with the TBM 10 to detect the risk factors such as an anomaly band, As a system, there is, for example, an electrical resistivity survey method described in Patent No. 10-1394332. In this method, a plurality of potential measurement modules are installed on the cutter head of the TBM 10 for excavating the excavation surface 2 to measure the electrical resistivity during excavation, To be predicted. In addition, seismic wave method and advanced horizontal drilling method are available, but TBM method often uses electrical resistivity measurement method.

According to an embodiment of the present invention, the automation module 120 is disposed at a place where the excavation surface forward prediction system 20 is installed, and is used to automatically acquire excavation surface data to be an electrical resistivity measurement value. And transmits the obtained excavation surface data to the data logger 110 by near field wireless communication.

The TBM 10 is a mechanized punching machine that rotates and rotates the front cutter head with a cutter head driving device. The TBM 10 includes a propulsion device for propelling the TBM 10 forward, an emitter for assembling the segments, And a buckling device (a cloaking device and a conveyor) for treating the tunnel, and can continuously perform all the tunnel construction processes such as excavation, buckle removal, and support work. The TBM controller 11 installed in the TBM 10 enables the operator to control the overall operation.

The TBM controller 11 is adapted to detect excavation progress data indicated by the operation of the TBM 10. The excavation progress data is generally 198 items, so that the operation state of the TBM 10 can be comprehensively grasped.

The data logger 110 may be disposed within the TBM 10 to be connected to the TBM controller 11 in the TBM 10 to obtain excavation progress data, And also receives excavation surface data transmitted in short-range wireless communication.

The data logger 110 includes a data selector 111 for selecting a pre-selected item for tunnel management among the excavation progress status data of the 198 items that have been acquired, and a data selector 111 for selecting from the excavation progress status data and the automation module 120 And a data converter 112 for collecting the received excavation surface data as tunnel management data and converting the collected data into a predefined data format so that the tunnel management data converted into the data format is transmitted to the AP 210 ).

Here, the selected excavation progress data includes excavation time, stroke, cutter pressure, jack pressure, total thrust, earth pressure / slurry pressure and cutter torque, including the operation state of the cutter head, the propulsion state of the TBM, To reflect the progress of excavation of the TBM (10). That is, data on drilling progress status of the TBM 10 can be accurately grasped at a remote site.

The data selector 111 included in the data logger 110 may generate an event signal indicating the presence of the specific data if there is specific data predefined in the collected tunnel management data, To the AP 210 as shown in FIG. For example, an event is defined as a case where a stroke, a cutter pressure, a jack pressure, a total thrust or a cutter torque deviate from an estimate derived in the pre-construction planning process, thereby notifying the middleware 300 of the occurrence of an event.

However, it is advantageous to simplify the configuration of the data selector 111 by analyzing the tunnel management data in the middleware 300 and detecting whether a predefined event has occurred, And it is also advantageous to obtain various analysis results. Of course, it is also good that the all-in-one system 30 receiving the tunnel management data from the middleware 300 grasps the event situation using the analysis program.

The tunnel management data transmitted from the data logger 110 in the short distance wireless communication is relayed through the tunnel routing system 200 constructed in the tunnel 1 excavated by the TBM 10 for multi- To the middleware 300.

As shown in FIG. 2, the tunnel routing system 200 is installed at a position spaced apart from a rear end of the TBM 10 by a predetermined distance. The tunnel routing system 200 includes an AP A gateway 230 which is disposed at the entrance of the tunnel 1 and is capable of connecting to the public communication network 40 and a gateway 230 which is spaced apart from the tunnel 230 between the AP 210 and the gateway 230 And a plurality of routers 220 arranged to relay the tunnel management data between the AP 210 and the gateway 230 in a multi-stage manner.

According to the patent document 10-1646969, each of the routers 220 and the gateway 230 compares the data received by the wireless communication path 201 and the data received via the optical communication path 202, To the rear router or gateway 230 on the communication path and if the data do not coincide with the data received through the wireless communication path 201 and the optical communication path 202, (Cyclic Redundancy Check), and transmits a reverse signal for retransmitting through the error-free communication path to the front-end router or AP 210 in the reverse direction, thereby retransmitting the data through the error-free communication path Relay transmission in the forward direction. In addition, a device code of both apparatuses (AP and router, router and router, or router and gateway) relaying transmission error intervals, and a communication path having a transmission error in the wireless communication path 201 and the optical communication path 202 And generates and transmits an event signal including the communication failure information that combines the identifiers indicating the communication failure information.

When an interval in which a relay error occurs in the multi-stage relay section from the AP 210 to the gateway 230 occurs, the gateway 230 transmits an event signal including device information, i.e., an equipment code, And transmits it to the middleway 300.

Each of the routers 220 can perform the AP 210 function by switching the operation mode so that a new router 220 is installed in an increased interval according to the advance of the TBM 1, And the relay 220 can extend the relay transmission path by communicating with the newly installed AP 210 through the router 220 functioning as the AP 210 to perform the relay function.

The tunnel routing system 200 configured as described above transmits the tunnel management data collected by the data logger 110 to the middleware 300 by the gateway 230 on the ground that can be connected to the public communication network 40, 300) to support remote monitoring and management using tunnel management data.

That is, the middleware 300 may be configured as a separate middleware server so as to be interlocked with the all-in-one system 30, or may be mounted so as to operate in an all-in-one system 30 programmatically. In the embodiment of the present invention, As shown in FIG.

Here, the management program of the all-in-one system 30 can be used for, for example, checking the real-time operation status of the TBM 10, grasping the progress of the construction reflecting the increase in the length of the tunnel 1 due to the TBM 10 being pushed, Risk management based on operating conditions, excavation frontal analysis based on excavation surface data, prediction of abnormal conditions (fracture zone, weak zone, etc.) and rock condition prediction, risk factor review and countermeasure planning, and decision support And it is desirable that commands can be issued to each node. In order to perform the functions of the all-in-one system 30, tunnel management data collected in real time is required.

The present invention is equipped with the middleware 300 that operates in cooperation with the all-in-one system 30 in order to collect and provide the tunnel management data necessary for executing the management program of the all-in-one system 30.

4, the middleware 300 includes a network interface component 310, a data integration module 320, a data layer 330, and an application interface component 340.

In the case of the consistency judgment, for example, it is judged whether or not a data format agreed with the data converter 112 of the data logger 110 is satisfied.

The data integration module 320 classifies the tunnel management data into excavation progress status data and excavation surface data and further subdivides the classified data into items and transmits the classified data to the data layer 330 to store the data in the database 331 in real time . Of course, when an event signal is transmitted, the event is additionally stored in the list.

Here, the event management module 333 does not have a function of analyzing the tunnel management data and detecting an event, but may instead support the event detection by the management program in the all-in-one system 30.

The application interface component 340 connects the data layer 330 with the all-in-one system 30 where the management program is executed.
