3D visualization of Metro makes everything under control

The Beijing Meteorological Observatory has issued a blue rainstorm warning signal again , Special weather 、 Take the subway during rush hours , It would be …… Know the annihilator in the Avengers ? With a snap of your finger, half the people disappear , If mieba goes by subway , You can say that , After a snap of your fingers ... He must still have no seat . It's said that someone brought a pot of cactus when they crowded the subway , As a result, the subway turned into a cactus , I don't know if this friend with cactus has pain in his hand , I think maybe the people around me are very painful …… What wonderful experiences have you encountered by subway ？

In today's tense situation , When many things begin to develop into processing on the Internet , The road to visualization is also clearer , View geographic location , Remote control warehouse , Remote video control , Automatic temperature and humidity control . In the past, this kind of thing was often monitored on the spot , Now it can be operated by visualization , Visualize the temperature and humidity 、 Visitors flowrate 、 as well as 3D The combination of model and reality , And collect various monitoring data through a series of collectors 、 Temperature and humidity data , The collected data is transmitted to the data gateway through the data bus or sensor , Then the gateway passes it to the cloud platform for processing , Finally, it will be displayed on the user's data screen, mobile phone or computer , Through such a series of operations , Remote data and real scenes will be processed into a three-dimensional visualization application that can be monitored and controlled .

The system adopts ThingJS To construct the subway station 3D Visual scene , It shows the real scene of a subway station from the front , Including the real-time operation of Metro , Subway up and down , Video surveillance , Smoke alarm , Elevator operation, etc , Help you intuitively understand the current subway station .

Three interaction modes are provided ：

First person model ： The operation is similar to the effect of pedestrian travel , You can control forward and backward through keyboard and mouse .

Automatic patrol mode ： No operation is required in this mode , The scene automatically moves forward and backward to check the scene of the current subway station .

Mouse operation mode ： Left click to rotate the scene , Right click to pan the scene .

Results the preview

Monitor device interaction

When we click the monitoring device in the scene, we can view the operation of the current device , Operation data and other information . After clicking the camera in the scene, the monitoring screen of the current camera will be displayed at the top of the right . Through video 、 Three dimensional visualization and other dynamic monitoring of the main processes of each business , Obtain the operation status of each business in real time , Alarm and linkage for abnormal conditions .

Smoke alarm monitoring

The smoke alarm will change the color of the current smoke alarm model according to the status value transmitted from the background in real time , Red is alarm state .

TV train arrival time monitoring

There will be a special TV in the daily subway station to show the arrival schedule of the next subway , This effect is also simulated in the system , But for the time being, the system modeled television .

Real time monitoring and management of passenger flow

Enter the gate data 、 The video monitoring data is connected to the visualization platform , Through the data obtained , The system can realize timely alarm for crowded places , Linkage video monitoring for real-time flow viewing , Guide and ease the flow of people .

The Internet of things will use a variety of information sensing devices , Real time acquisition any monitoring required 、 Connect 、 Interactive objects or processes, etc , Through and with ThingJS The combination of can better show the advantages of Visualization . Subway visualization project , Integrated vehicle operation 、 Customer service 、 Emergency command 、 Energy monitoring 、 Equipment and facility monitoring and other professional data , For emergency command 、 Provide necessary data support for passenger flow guidance , Further improve the subway service quality 、 Reduce safety risks and impacts , Let everything in the subway be under control .
