Problems solved by technology
Existing railway oxygen generating equipment supplies oxygen when people are unwell or sleep at night, which cannot provide a stable oxygen environment and consumes a lot of energy. At the same time, the equipment has no dynamic monitoring status, and operators need to check it regularly. When a failure occurs, it is necessary to analyze the cause The solution can only be specified after the location and location, the workload of the maintenance personnel is heavy and the efficiency is low

Embodiment Construction
[0065] The present invention will be described in detail below in combination with specific embodiments.
[0066] The invention relates to a digital twin system for an oxygen environment for a plateau railway and oxygen production equipment, including two digital twin subsystems, namely, a digital twin subsystem for an oxygen environment and a digital twin subsystem for oxygen production equipment.
[0067] The oxygen environment digital twin subsystem maps the oxygen environment and its environmental information into the BIM model to form a digital twin relationship. After the simulation calculation, the oxygen production equipment is controlled according to the result feedback, thereby implementing the adjustment of the oxygen concentration of the oxygen environment. The oxygen environment digital twin subsystem specifically includes:
[0068] The first information collection module collects oxygen concentration information, altitude information, and number of people in the ...

The invention relates to a digital twin system of an oxygen environment for plateau railways and oxygen generating equipment. The working environment in the plateau area is difficult, and oxygen generating equipment is one of the most difficult projects in railway construction. At present, there is no remote real-time control method for oxygen generating equipment with high efficiency. The present invention includes an oxygen environment digital twin subsystem and an oxygen production equipment digital twin subsystem, each of which includes an information collection module, a digital simulation module, a calculation judgment module and a feedback control module, and uses a BIM model to digitally monitor the oxygen environment and oxygen production equipment. Twin, simulation, calculation, feedback control, to achieve the purpose of remote real-time control. This system plays a positive and direct role in reducing operating costs, improving operation and maintenance efficiency, and optimizing equipment management.
Description
technical field [0001] The invention relates to the technical field of self-adaptive control of plateau railway oxygen production equipment, in particular to a digital twin system for plateau railway oxygen environment and oxygen production equipment. Background technique [0002] Digital twin technology is to make full use of data such as physical models, sensor updates, and operation history, integrate multi-disciplinary, multi-physical quantities, multi-scale, and multi-probability simulation processes, and complete the mapping in the virtual space to reflect the entire life of the corresponding physical equipment. cycle process. The digital twin system includes the twin relationship between the physical equipment and its digital phantom, which can completely bypass the physical equipment and directly simulate and emulate through the digital phantom, thereby realizing feedback control of the physical equipment. [0003] The working environment in the alpine and high-alti...
