Abstract

The present invention relates to an RTK-based integrated control system for underground buried structures for the prevention of disasters and safety accidents. The system of the present invention comprises: a DGPS receiver for receiving GPS data and DGPS correction data from GPS satellites and DGPS base stations and calculating current GPS location information based on the GPS data and DGPS correction data; a first terminal device connected to the DGPS receiver via wired or wireless connection for receiving current GPS location information calculated by the DGPS receiver; and a buried structure management server in which buried structure modeling data corresponding to the GPS location information is stored. The HMD device includes a mixed reality application that is connected to a first terminal device via Bluetooth communication, receives GPS location information from the first terminal device, transmits the received GPS location information to a buried object management server containing buried object data, receives buried object modeling data corresponding to the GPS location information from the buried object management server, and displays the received buried object modeling data on the screen of a head-mounted display (HMD); the HMD device includes a spatial recognition camera, and the mixed reality application recognizes a floor surface from an image input through the spatial recognition camera, forms a virtual floor surface for the recognized floor surface, and creates a buried object modeling object on the formed floor surface.

Description

RTK-based underground facility integrated control system to prevent disasters and safety accidents The present invention relates to an RTK-based integrated control system for underground buried facilities for preventing disasters and safety accidents, and more specifically, to an RTK-based integrated control system for underground buried facilities for preventing disasters and safety accidents that can contribute to accident prevention by providing location information of underground buried facilities such as water pipes, electricity, telecommunications, and gas pipes, as well as information on seven major buried pipes, using DGPS and mixed reality technologies in a 5G environment. Generally, methods for locating underground facilities, including water pipes, sewer pipes, gas pipes, communication lines, and power lines, are known to include methods using drawings, methods using GIS, and methods using radio frequency identification systems (RFID). Regarding methods for locating such underground facilities, the method using drawings is inconvenient to carry and difficult to view, while the method using GIS is difficult to verify on-site. Furthermore, the locations of underground facilities such as water pipes, sewer pipes, and gas pipes are currently kept confidential as they are owned by local governments. Consequently, despite the critical importance of accurately identifying these locations for both management and construction personnel, incorrect location selection continues to cause inconvenience and accidents of varying severity, such as water pipe ruptures and gas explosions. Recently, there are predictions that mixed reality devices could replace smartphones once the 5G era begins. Mixed Reality (MR) refers to a technology that implements a more advanced virtual world by compensating for the shortcomings of Virtual Reality (VR) and Augmented Reality (AR). VR, which has recently gained popularity in the entertainment market, is a concept that completely transports the user into an artificial virtual reality. Consequently, it has the disadvantage of focusing only on what is visible through a small screen in a fixed position. On the other hand, AR is a technology that superimposes some processed images or information onto the user's reality to make objects appear as if they are naturally existing. Games like "Pokémon GO," where virtual game characters appear alongside the real-world view captured by a smartphone camera, are representative examples of the application of AR technology. In contrast, MR is a concept that transfers virtual reality into the real world. In other words, it refers to an advanced form of AR visible in the real world. MR measures the depth and shape of objects visible in real-world video and adds virtual images in 3D form, allowing for a more realistic 360-degree view of the virtual image. Therefore, unlike VR, it cannot exclude reality and inevitably interferes with reality in some form. The advantages of MR include the ability for users to recognize their precise physical location, enabling freedom of use, and the support for diverse content. It is expected that the introduction of MR into industrial settings will allow work to be performed in a manner a step more advanced than existing work methods, and it is currently gaining attention as a new industry.
