Description

Guide and Control System for Excavating Work,

The present invention relates to an excavation work guide and control system capable of high-precision GPS surveying. More particularly, the present invention relates to a digging operation guide and a control system, And more particularly, to a digging operation guide and a control system capable of accurately measuring the workload of the work area while blocking the contact with the excavation work.

Generally, in the earthworks work of construction work, the allocation and transportation plan of the soil is established by the experience of the construction designer. Based on this plan, the equipment operator can use various heavy equipment (excavator, loader, To perform the earthwork operation.

In order to carry out such earthworks work, surveying work is required to survey the work location, the area and the depth of the earthwork. That is, a work inducer is introduced to induce the work of the excavator together with the driver for driving the excavator in the earthwork work. Further, a surveyor for passing the depth of the earthwork to the driver is inputted while confirming the design drawing of the construction site, The earthworking work is carried out while carrying out passive surveying work using the instrument and the surveying rod (staf).

However, since the surveying engineer is directly put into the field and the surveying work is carried out by the manual measurement method, the surveying work carried out by the surveying engineer is delayed in the overall working time and the air is lengthened. Further, As the excavation work is carried out only by intuition and experience, it is difficult to perform accurate earthworking work, safety is not guaranteed, and productivity is not uniform.

As a conventional technique disclosed for solving the above problems, Korean Patent Registration No. 952482 (Apr. 05, 2010) discloses a stereo vision system including a stereo vision camera that enables three-dimensional modeling of a ground shape, A measurement distance corrector provided at a front portion of the stereo vision camera and including a rotatable body rotatably supported via a drive shaft of a drive motor unit for acquiring a video signal for each stage of the excavation object; A driving motor unit that rotates the measurement distance corrector according to a rotation mode command of the input unit, and a driving motor unit that adjusts magnification correction in the measurement distance corrector, An image sensing unit for receiving the image signal of the obtained object, And a control unit for analyzing the image signal of the object inputted to the sensing unit and rotating the driving axis of the driving motor unit by the rotation angle of the measurement distance corrector, so that the ground shape is recognized in real time using the stereo vision of the lens changer system There is known a system for realizing a three-dimensional ground shape image using a rotatable multi-magnification lens capable of calculating the post-earthwork amount.

In addition, in Japanese Patent Laid-Open Publication No. 53070 (June 26, 2003), there is disclosed a boom resolver angle sensor mounted on a rotating part of a boom for measuring a rotation angle of a boom, A bucket resolver angle sensor mounted on a rotating portion of a bucket for measuring a rotation angle of the bucket, an inclination angle sensor for measuring an absolute horizontal value of the excavator, a boom resolver angle sensor and a female resolver angle sensor And a monitoring device for receiving a signal from the bucket resolver angle sensor and the inclination angle sensor and converting the signal into position information of the working device and displaying the error code of the main controller in a character form by serial communication with the monitoring device and the main controller of the excavator It is possible to check the information of the work situation in real time and improve the work speed, The excavator has a working machine monitoring systems are known which can be reduced.

However, in the case of the above-mentioned prior art, only the ground shape image is implemented while correcting the measurement distance based on the image of the vision camera, whereas in the case of the publication No. 53070, Since the state is measured by the angular value and implemented as a letter, it is difficult to obtain clear working data according to the depth of the earth for both of them, and the accuracy of calculation of the excavation volume is low and the information accuracy to be transmitted to the driver is low.

In addition, since it is difficult to obtain clear underground information at the excavation work site in the past, base information related to another underground buried material (for example, oil pipeline, water pipe, other pipeline, etc.) is unclear in the underground, There is a problem that the safety of the work is lowered, such as being faced with a dangerous situation, and the cost is lost due to the repair due to the breakage of the underground buried object.

To convert the TIN data into the TIN data, the TIN data generator 30 converts the data to generate a three-dimensional irregular triangular network according to the drawing conversion.

The irregular triangulation network is a network that generates terrain for three-dimensional and surface processing using input data, and is automatically generated by an internal irregular triangular network generation algorithm programmed from the TIN data generator 30, The criteria are applied when calculating the excavation volume.

In order to generate the plan surface in the TIN data generator 30, the CAD drawing input from the outside is outputted to output the plan plan drawing on the plane, and the data is converted into the structure in which the irregular triangular network is connected to the drawing of the plan plan In order to generate the work surface in the TIN data generator 30, an irregular triangle network is created on the earthwork work surface based on the coordinate data input from the coordinate value measurer 20, And generates and outputs an irregular triangular mesh of the earthwork work surface in which the coordinate data input from the value measuring unit 20 is connected in line.

In the case of the plan surface and earthwork work surface outputted from the TIN data generation unit 30 on the screen output means 11 of the user guide module 10, they can be output as lines of different colors and can be visually distinguished from the driver .

In this case, the plan surface or the earthwork work surface is output in the form of overall drawing through the screen output means 11 of the user guide module 10, while the present position of the excavation equipment 1 is outputted on the output drawing, The user can operate the user guide module 10 to enlarge or reduce the drawing and to output only the partial area of the entire plan surface or the earth work surface.

That is, the information calculating unit 40 can output the distance D1 to the design surface and the distance D2 to the underground buried object based on the coordinate value of the current position of the bucket, respectively.

For example, referring to FIG. 5, coordinate points for the current working position of the bucket 9 are measured and output as a coordinate value (+0.86), as well as from the working position of the bucket 9 to the excavation design surface And outputs the coordinate value (+15.20), and the distance D2 from the working position of the bucket 9 to the underground object A is measured to output the coordinate value +12.35, It is possible to secure the distance information with respect to the underground object (A) in addition to the distance information on the depth of the earthwork work, thereby stably progressing the work.

When the bucket 9 reaches the distance to the excavation plan surface It is possible to output a warning message and to output a warning message when the bucket 9 approaches the distance closer to the set value set as the accessible distance to the underground object A. [
