Beijing Labor Insurance Vocational School - VR water supply pipeline inspection

Project Client: Department of Safety Engineering, Beijing Labor Security Vocational School

Brief introduction of the project: The safety technology and management (city management and supervision direction) of the Safety Engineering Department of Beijing Labor and Social Security Vocational College is currently the only professional in the country dedicated to ensuring the safe operation of urban underground pipelines, and it is the safe operation of urban underground pipeline network. Under the premise of maintaining and delivering high-quality talents, the safety engineering department aims to carry out the training of the pipe network in the school and proposes the cooperation needs. The company is custom-made to develop the teaching software for leak detection of water supply pipes according to the needs of the department.

Experiencer's practical operation--contact detection instrument

VR pipe network detection teaching software is a new attempt of virtual reality and pipe network detection disciplines. It uses advanced virtual reality means to construct virtual urban scenes and restore the real working scenes of pipe network inspection personnel. Let the experiencer conduct a complete pipe network inspection and verification according to the guidance. In the process of using the software, students need to use the testing equipment correctly and follow the standardized testing process. In this teaching software, take full account of real environmental factors. For example, when entering the sewer, you need to kneel down and use the virtual reality peripheral to move the heavy manhole cover and climb to the bottom of the sewer. You need to correctly answer the built-in questions and eliminate various obstacles. Through repeated experiences, students can fully grasp the testing process. After repeated experience, it is easy to understand that the tester is not working hard.

Technical points of the project:

1. Build an overall street scene to simulate a real working environment

2. Fine instrumentation of equipment instruments: measuring instrument main box, measuring instrument main unit, measuring box (with sensor), sewer manhole cover and valve pipe, one to one simulation of actual objects

3. Detect process logic to simulate the entire inspection process

4. The instrument uses logic to simulate normal opening and use of related instruments

5. Experience the situation of going down the well under different oxygen levels. There are three cases:

(1) Pull the manhole cover and check the oxygen concentration. If it is between 18% and 22%, you can go straight down the well.

(2) Pull the manhole cover and check the oxygen concentration. If it is lower than 18%, it must be forcedly ventilated by a fan, and then the oxygen concentration should be detected. If it is between 18% and 22%, the well can be lowered.

(3) If the well cover is opened and the oxygen concentration is not detected, the hazard will appear, indicating that “the oxygen concentration is insufficient and the suffocation is dangerous”.

6. Design the excavation detection logic, perform virtual excavation after the test is completed, and experience the surreal verification process.
