Description

Dam sluice discharge simulation system and method using 3D digital twin dam model {Dam sluice discharge simulation system and method using 3D digital twin dam model}

The present invention relates to a dam flood gate discharge simulation system and method using a 3D digital twin dam model. Dam sluice discharge simulation system and method using a 3D digital twin dam model to manage the dam storage water through simulation of releasing the stored water stored in the dam under various conditions when the water level of the dam becomes a certain standard or higher It is about.

In general, various dams are constructed to secure water by blocking the flow of rivers or to prevent a rapid increase in downstream flow due to floods.

However, there is a lack of basic data for safety management due to insufficient preservation of valuable information at the time of dam infrastructure construction, and computerization of essential information such as drawings, construction, physical properties, and measurement information of infrastructure completed before 2000 is insufficient.

In addition, it was difficult to support rapid decision-making due to the individualization and decentralization of information, and user accessibility was limited because dam inspection and diagnosis data were individually preserved in the form of paper reports. has become important

In addition, the skill, experience and know-how of the existing engineers are important, it takes a considerable amount of time for new transfer employees to become skilled, and dam inspections are limited to visual inspections by dam facility managers, and inspections in restricted access areas are difficult. there is.

In addition, the need for real-time collaboration to support rapid decision-making in the event of safety hazards at dam sites is increasing.

Meanwhile, as part of the Green New Deal, the government will introduce unmanned aerial vehicles (drones) for dam safety inspections in earnest from the second half of 2020, and by 2025, a three-dimensional virtual space (digital twin) and artificial intelligence (AI)-based 'dam smart safety The management system will be established step by step.

Digital twin refers to a virtual space that is used to identify and solve problems that may occur in the real world by implementing machines and equipment in the real world in a virtual world in a computer.

'Dam Safety Inspection Using Unmanned Aerial Vehicle' is a functional safety inspection method in which the state of the dam is captured using an unmanned aerial vehicle and then implemented as 3D graphics to check whether the dam body is damaged.

In the past, when a person directly went to a dam site to check for defects, it was difficult to access places that were difficult to access, but drones can be used to inspect dams more meticulously.

In the three-dimensional dam virtual space (digital twin) scheduled to be built from 2021, photos and video data inspected by drones can be accumulated and input. When such huge data (big data) is accumulated, artificial intelligence (AI) can be used to check the presence or absence of abnormalities in the dam.

Therefore, the government expects that by preemptively reinforcing and repairing dams by introducing advanced technologies, the ability to respond to crises will increase and the performance of aged dams will be improved so that dams can be operated safely for a long time.

Here, the dam sluice discharge simulation system 100 using the 3D digital twin dam model may include a sluice gate opening and closing device for sluice discharge. The dam body 110 is installed in the form of a dam or dam across the valley, but forms an overflow part lower than the height of the dam shoulder between the dam shoulders in contact with the valleys on both sides. It overflows through the overwater part of the stream and is discharged downstream. In addition, a plurality of outlets penetrating from the upstream to the downstream are formed at the bottom of the dam body, so that even in a situation where a small amount of valley water is continuously introduced, it is discharged downstream through the outlet. Therefore, the sluice gate opening and closing device needs to store valley water at a predetermined level in the dam for the purpose of providing habitat space for fish, supplying surrounding water, or preparing water for fire prevention, so a valve is installed at the outlet to adjust the water level do. This valve is configured to install an electric motor in a safe place from water (for example, the dam shoulder shown in FIG. 1) and transmit the rotational power of the electric motor to the valve, so that it can be controlled manually as well as remotely. .

The sluice gate opening and closing device according to an embodiment of the present invention is installed away from the valve installed at the outlet of the dam body 110 and opens and closes with a rotating means installed in a position where there is no risk of electric leakage accident due to water.

Even if the pipe is a flexible tube, as described above, the flexible rotation shaft is also flexible, so it can rotate smoothly inside. The flexible rotational shaft has a plurality of bearings extrapolated at intervals from each other along the length direction. At this time, since the flexible rotational shaft having a bearing on the outer circumferential surface must be inserted into the pipe, the flexible rotational shaft can be easily inserted and rotated smoothly by using a pipe having an inner diameter larger than the outer diameter of the bearing. The flexible rotating shaft inserted into the pipe and installed has one end inside the rotation means and the other end inside the reducer so that when one end is rotated, the other end is also rotated. The rotating means is configured to rotatably rotate one end of the flexible rotating shaft and torsionally rotate it with the rotational force of the power source. According to an embodiment of the present invention, the power source is composed of a motor capable of normal and reverse operation and a manual knob rotated by a person's hand, and one end of the flexible rotation shaft can be torsionally rotated by selecting between the motor and the manual knob. The rotating means includes a motor capable of normal and reverse operation; A manual knob that is vertically rotatable so that a person can rotate it by hand; a shaft that is rotatably installed vertically; A main gear fixed to the lower end of the shaft; A driven gear meshed with the main gear, rotated by the main gear, and fixing one end of the flexible rotating shaft to the rotating shaft; a first clutch selectively transmitting the rotational force of the motor to the shaft; a second clutch installed on the top of the shaft to selectively transmit the rotational force of the manual knob to the shaft; And it can be configured to include a rotation sensor for detecting the rotation number of the shaft. Since the rotational axis of the motor is horizontal and the first clutch is installed at the end of the rotational shaft of the motor, the rotational axis that is interrupted by the first clutch is also placed horizontally, so that the rotational force of the motor that is interrupted by the first clutch is transmitted to the shaft by the bevel gear. do. If the rotational axis of the motor is vertical, rotational force can be transmitted to the shaft using a spur gear. In addition, a speed reducer may be installed between the motor and the first clutch so that power is transmitted through the first clutch at a rotational speed lower than that of the motor.
