Create a green city and 3D visualization of digital twin natural gas stations

Preface

Natural gas as a common fuel , Closely related to our life , And for the storage and transportation of this fuel , There are strict requirements for natural gas supply stations . Gas enterprises generally design point supply stations as unattended stations , And often in the process of operation management , The safety management of point supply station is particularly important . When an accident happens , The display of early warning methods and response plans has become an indispensable part .

For the gas industry , Using advanced emerging technologies , Such as artificial intelligence 、 The Internet of things 、BIM It is the trend of the future to build a new management mode , use Hightopo（ hereinafter referred to as HT ) Innovative 2D/3D Visual modeling technology , Digital twin natural gas station 3D visualization system , Provide a set of exhibits 、 monitor 、 early warning 、 Plan in one solution . Enabling gas industry to informationize 、 visualization 、 Green environmental protection direction development .

Often mentioned traditions BIM It is widely used in engineering design and construction , The biggest feature is that the expression of three-dimensional model is better than traditional CAD The drawings are more vivid , Most of them are used to assist drawing review 、 Visualization 、 Collaborative construction and so on , But its implementation cost is high , Need professional and technical personnel to spend a lot of time on project construction . In addition to the basic shape display information of the model , It also contains a lot of business and hierarchy information , So general BIM The files are very large , A few hundred MB Up GB Both have , This is loaded in real time for all the presentation content Web It's almost a bottleneck .

Hightopo The visualization uses lightweight modeling to build the scene effect , Model effects are mainly represented by maps , In order to ensure efficient loading and smooth running in the web page . And can provide import IFC Format BIM function , Use... In some scenarios BIM Information reduces development costs . make 1:1 High simulation modeling effect, visual scene .

Effect display

On the left and right sides of the interface are 2D panel , The left side shows the temperature of the device 、 Pressure and pipe flow information , On the right is the function switch panel , 2D The interface is science fiction . The center of the interface shows the main body of the natural gas station 、 pipeline 、 Equipment and other overall simulation of three-dimensional landscape .

Systems analysis

Park monitoring

Use realistic style to create 3D effect of natural gas station , Through the big screen 、PC Or drag the mobile device interface to change the current perspective , You can also zoom the interface . Hovering the mouse over the corresponding facility will display the device details tab , Support real-time viewing of equipment operation information .

Intelligent inspection

In no man's Park , Patrol intelligent robot according to the designated line , Patrol and check the point equipment one by one , Collect and analyze real-time visual operation data , The abnormal data is fed back to the control center at the first time , Provide the basis for management to deal with .

Structural scanning

Transparent architectural appearance , Use the building model wireframe , The overall layout structure of equipment and facilities can be viewed directly 、 Running state . When the facility fails , It's going to be a red alert , Remind the management personnel of timely prevention and control and take corresponding measures in a visual way .

Live video

Through access to the monitoring equipment set up at each point in the park , Support real-time view of real-time image of plant area , Provide timely and effective information for management department .

Fire control simulation

As fuel, natural gas is very dangerous for natural gas stations with huge storage capacity , The requirement for its safety is also very high . Pre planned fire lines 、 Personnel rescue plan, etc , Through the three-dimensional scene simulation simulation scene fire rescue , Provide reliable and effective information for fire rescue work .

Research and judgment process

This paper mainly introduces that in case of fire , After receiving the fire information , The research and judgment process of the early warning system , Including the early warning process 、 Judge whether the emergency start-up plan is reached 、 Emergency start 、 Emergency disposal and emergency termination information .

Realize the value of

For natural gas point supply station, the safety risk characteristics mainly include the following three points ：

1. Low temperature risk

The storage of liquefied natural gas has strict requirements for temperature , The saturated vapor pressure should be close to the normal pressure of high temperature . No matter in the process of storage, transportation and use of liquefied natural gas, the critical point of its temperature should be ensured . At the same time, in the process of storage and transportation in LNG supply station , To ensure that the materials of the equipment meet the low temperature performance , Avoid low temperatures , Otherwise, the cracking and shrinkage of liquefied natural gas will occur , It will bring certain risks to the natural gas supply station .

2. Burning risk

The combustion range of LNG is 6%-13%, The burning rate of LNG is about 0.3m/s, If in a sealed environment , Liquefied natural gas and steam can explode due to combustion ; But in an open environment, LNG and steam are less likely to explode . When LNG vapor meets an open fire It's flammable , It's also very easy to spread to places with oxygen .

3. To manage risk

Natural gas point supply station has the advantages of simple process 、 Low cost and so on , And often in the process of operation management , The safety management of point supply station is particularly important , The risk of safety management of point supply station is mainly reflected in the imperfection of safety management rules and regulations , Standardization of point supply station work 、 Standardization is not specific enough , The safety management responsibility system is not implemented , Related internal and external operators' safety training is not in place , Safety inspection and hidden danger treatment are not timely , There are many risks such as the scope of emergency treatment and the failure of emergency measures to be timely and effective .

in summary , The safety management of natural gas station is very important , At the same time, there is an urgent need for a perfect visual monitoring system to support its security management , Maintain normal operation .

summary

visualization 、 Digitization 、 Intelligent supervision is the development trend of gas industry , Greatly improved management efficiency , A lot of manpower and material resources are saved . With the rapid development of information technology , utilize HT The combination of visualization technology and intelligent supervision , With an effective early warning program , It can ensure the safe, efficient and orderly production .
