Then, the control unit 12 reads the project file stored in the storage unit 15 to be displayed on the screen when a project file open request signal received from the surveying engineer at the site to excavate the tunnel ( S102) (see FIG. 3G).

Next, the control unit 12 reads the project file and displays configuration information between the instrument 20 for performing a tunnel survey and the personal portable terminal 10 for visually expressing the surveyed survey information while being displayed on the screen. Receiving the input to enable a smooth communication between the instrument 20 and the personal portable terminal 10 (S102). At this time, in the present embodiment has been described by connecting the instrument 20 and the personal portable terminal 10 with a connection cable 15, it can be implemented by wireless.

The environment setting information may include model setting information, communication setting information {for example, a port, measurement time (eg, surveying information measured after surveying) of an instrument input through an input window as shown in FIGS. 3H and 3I. Time)}.

Next, the control unit 12 receives the machine point coordinate information and the measurement site setting information of the instrument 20 to be surveyed and transmits it to the instrument 20, and then automatically surveys the survey site setting information according to the survey site setting information. In step S200, a tunnel surveying process is performed to receive the surveying information. At this time, the instrument 20 is an automatic moving equipment by the motor using an automatic non-target equipment.

The tunnel surveying process is described in detail with reference to FIG. 3B, and the control unit 12 is the machine point coordinate information and substantially the machine point coordinate information of the surveyor 20 installed at the site to excavate the tunnel through the input unit 13 from the survey engineer. The survey part setting information to survey the tunnel is received (S201).

The machine point coordinate information and the surveying part setting information to be surveyed, which the instrument is installed, are input through an input window as shown in FIGS. 3J and 3K.

Machine point coordinate information of the instrument may include machine point coordinates N (e.g. 345123.931), E (e.g. 195421.547), Z (e.g. 365.175), instrument height (e.g. 1.5), prism radius (E.g., 3) and the like, and the survey part setting information includes a start station (e.g., 30937), an end station (e.g., 30947), an interval (e.g., 3), and a tunnel center as the origin. Start angle (eg 0 degrees), end angle (eg 180 degrees), spacing (eg 1), centerline spacing (eg 0), ground clearance (eg 0) , Measurement surface (e.g., shockcrete), station tolerance (e.g., 3), maximum measurement frequency (e.g., 3), and the like.

Thereafter, the controller 12 determines whether a survey start instruction signal has been received (S203). As a result of the determination in step S203, when the survey start instruction signal is not received, the standby state is maintained for a predetermined time.

As a result of the determination in step S203, when the survey start instruction signal is received, the controller 12 transmits the survey position setting information together with the received survey start instruction signal to the instrument 20 which is automatically moved by a motor, and then the instrument ( 20) receives the surveying information automatically measured as the surveying site setting information through the connection cable 15 (S205).

That is, as shown in FIG. 3L, the laser beam is irradiated to receive the survey information including the coordinate information of the irradiated point as the received survey part setting information.

Referring to the process of surveying by the instrument 20, the control unit 12 calculates the position to be measured as the measurement interval in the cross section to be measured in the measurement interval N, E, Z when receiving the start station, end station and station interval Based on the calculated N, E, and Z, the horizontal angle (Hz) and the vertical angle (V) are calculated from the location of the currently positioned instrument 20, and the information (horizontal angle, vertical angle) to be sent to the instrument 20 is calculated. After processing to the data type suitable for the model is transmitted to the instrument 20.

Then, the instrument 20 moves the instrument according to the transmitted information (horizontal angle, vertical angle) and sends a movement completion confirmation signal to the personal portable terminal 10 through the connection cable 15, and then the personal portable terminal ( 10) When the survey start signal is input, the survey data is converted into a data format suitable for the type of the instrument, and after the survey signal is transmitted to the instrument, the survey is performed by the instrument and then the surveyed survey information (N, E, Z, Hz). , V, SD, and HD) are transmitted to the personal portable terminal 10 through the connection cable 15.

The controller 12 causes the received survey information to be displayed on the screen (S207). At this time, by reading the project file stored in the storage unit 15, the survey information is displayed so as to overlap with the cross-sectional data displayed on the screen can easily check the amount of excavation.

In addition, the control unit 12 visually displays the calculated information, stations, measurement cross-sections, coordinates, etc. by calculating left and right distances, ground elevations, excavation rates, and station differences of the surveyed stations according to the surveyor's request for viewing a station ( S209) (see FIG. 3M). At this time, the left and right distance, the ground height, the excavation amount and the station difference of the station is calculated by comparing the survey data of the surveyed station with the basic data stored in the project file.

By doing so, the surveying site setting information input from the surveying engineer is transmitted to the automatic moving instrument by a motor, so that surveying of the excavated surface, the shock surface, and the lining surface of the tunnel can be performed automatically.

Hereinafter, a method for marking blast points based on a computer-aided design method implemented by the tunnel program will be described with reference to FIGS. 4A to 4C.

4A is an operation flowchart illustrating a blast marking method based on a computer-aided design method according to the present invention. FIG. 4B is an exemplary view showing an input window for inputting survey location information. An example of a screen showing an input window for inputting blast point coordinate information for marking a blast point.

First, referring to FIG. 4A, a method for marking blast points based on a computer-aided design method is described. The controller 12 executes a tunnel program that is already installed in response to a tunnel program execution request input from a survey engineer, and then tunnels. Receives a project file generated using the basic data including linear data, longitudinal data, section data and section data for each section for surveying (S300). At this time, the received project file is stored in the storage unit 15.

Subsequently, the control unit 12 reads the project file stored in the storage unit 15 to be displayed on the screen when a project file opening request signal received from a surveying engineer is received at the site to mark the blasting point. (S302).

Next, the controller 12 reads the project file and displays the instrument 20 for irradiating a laser beam to the position of the blasting point while being displayed on the screen, and a personal portable terminal for visually expressing coordinate information of the blasting point ( By receiving the configuration information between the 10) to facilitate the communication between the instrument 20 and the personal portable terminal 10 (S304).

In this case, the environment setting information may be model setting information of the instrument, communication setting information (for example, a port, a measurement time (time taken for the surveying information to be input after surveying), etc.), and the detailed information thereof is as described above. Are omitted.

The control unit 12 receives the machine point coordinate information, the surveying site information and the blasting point coordinate information of the instrument 20 to irradiate a ray to the position of the blasting point (S306).

Then, the controller 12 causes the location of the blasting point to be displayed on the screen based on the received blasting point coordinate information (S308). At this time, by reading the project file stored in the storage unit 15, the blasting point position information is displayed to overlap with the cross-sectional data displayed on the screen, it is possible to easily confirm the blasting point position.

Thereafter, the controller 12 determines whether a blasting point marking start instruction signal has been received from the surveying engineer (S310). As a result of the determination in step S310, when the blasting point marking start indication signal is not received, the standby state is maintained for a predetermined time.

As a result of the determination in step S310, when the blasting point marking start indication signal is received, the controller 12 transmits the blasting point coordinate information to the instrument 20 together with the received blasting point marking start indication signal so that the instrument coordinates the blasting point. The laser beam is controlled to be irradiated in the order of the measurement interval and the measurement number based on the information (S312).

In other words, the relative coordinates on the cross-section of the blasting point to be found are obtained by the actual coordinates (E, N) through the planar and vertical lines, the angle difference between the mechanical point and the actual coordinates is obtained, and the instrument is moved. This will indicate the location of the point. The explosives can be blasted by manually installing explosives at the marked blasting points.

When the laser beam is irradiated to the blasting point by the instrument 20, the control unit 12 receives the start station, the end station, and the station interval, and inputs a measurement position for the blasting point data in the section to be measured. , E, Z, and calculates the horizontal angle (Hz) and the vertical angle (V) from the position of the currently located instrument 20 based on the calculated N, E, Z, and sends the information to the instrument 20 (horizontal angle, Vertical angle) is processed into a data form suitable for the model of the instrument and then transmitted to the instrument 20.

Then, the instrument 20 moves the instrument according to the transmitted information (horizontal angle, vertical angle) and sends a movement completion confirmation signal to the personal portable terminal 10 through the connection cable 15, and then the personal portable terminal ( 10) When the blasting marking signal is input from the blasting point marking signal is converted into a data type suitable for the model of the instrument and transmitted to the instrument 20 through the connecting cable 15, the laser beam is positioned at the blasting point position by the instrument 20 To be investigated.

In this way, the blasting point for forming the excavation surface, the shock concrete surface, and the lining surface to excavate the tunnel is marked.

By doing so, the blasting point can be easily marked by irradiating a laser beam to the blasting position based on the blasting point coordinate information and the machine point coordinate information to be received from the surveying engineer.
