preface
With the progress and development of society, the pace of building smart city is constantly advancing, and smart park has become the focus of urban planning and social development. As an important part of smart city strategic planning, smart park is more like the epitome of smart city, which permeates all aspects of smart city construction. The intelligent construction of the park not only improves the attraction of the park, but also promotes the sustainable development of the park, provides the foundation for the development of strategic emerging industries, and complies with the trend of information technology innovation and application, which is not available in traditional industrial parks.
The third phase of Xiamen Software Park is located in the north of the core area of Jimei New Town, the south of Houxi Town, the east of Guankou Town, and the west of Jimei Culture and Education Zone. Backed by henan Mountain, facing Xinglin Bay, close to Jimei New Town and Yuanbo Garden, it is an important part of Jimei New Town. This paper will use Xiamen Software Park Phase III as the carrier, using HT rich 2D, 3D configuration to build a Three-dimensional visualization system of Xiamen software Park Phase III – intelligent park.
Results show
This case adopts manual placement of points in the park, which is suitable for projects with a small number of points distributed in the park worldwide. When the number of distribution points is large, it can be considered to automatically generate coordinate points by accessing the longitude and latitude information of each park. Simple trigonometric functions are used to carry out spherical coordinate algorithm to achieve the expected effect. In this way, WebGIS related functional modules are completely unnecessary, and manual placement of the workload is eliminated, which greatly improves the efficiency of project implementation.
China map scene:
The earth in the form of 3D is supplemented with matching geographical environment map to carry out 3D virtual simulation display, focusing on reflecting the boundary of The Map of China, and highlighting the point of the park through color differentiation, double-clicking the point can enter the next level map scene.
Xiamen map scene:
The location information of the park in Xiamen is reflected by marking the location of the park on the THREE-DIMENSIONAL Map of Xiamen. This display mode is suitable for the park with scattered and multi-point distribution. You can select the point you want to view and double-click the corresponding point to enter the detailed scene.
Scene of Xiamen Software Park Phase III:
The overall scene design is based on realistic style. Through 3d modeling of buildings and roads in the park, the whole situation of the park is simulated and restored. Combined with the engine rendering independently developed by Hightopo to create a magnificent park scene. Support 360-degree omni-directional browsing without dead Angle, through the HT built-in interaction, you can realize the mouse rotation, translation, close and far operation. At the same time, it also supports cross-platform browsing, which can be easily opened by any mobile terminal, which is an advantage that THE C-terminal platform does not have. In addition, the operation of single finger rotation, double finger zoom and three finger translation of touch screen devices need not worry about different cross-platform interaction modes.
Q&a mini-module:
People often ask, they already have a 3D model, can they just use it?
BIM model: BIM is often used for the integration of building information, which not only contains geometric information, professional attributes and status information describing building components, but also includes status information of non-component objects, so the volume of conventional BIM model files is relatively large. Loading hundreds or thousands of megabytes of models in real time is not practical for a Web where presentation content is loaded in real time. Although we do not recommend the direct use of BIM, we do support BIM and can provide the BIM function to import IFC format to reduce development costs in some scenarios.
Other models: the existing models on the market may use 3Ds Max, C4D, Solidworks and other commonly used design software, but most of the models are mainly designed to restore the appearance of the models at the beginning of modeling, without considering the lightweight work such as surface reduction. When there are too many model planes in the scene, it will produce too much loading load on the Web, resulting in the whole page stalling or even crashing.
Hightopo 3d visualizations are all scenes built by designers using lightweight modeling, and the model effects are mainly presented by maps. Combined with the powerful rendering capability of HT engine, the scene can be efficiently and smoothly loaded and run in the Web and the scene can be effectively visualized.
Environmental simulation variation
The scene is decorated with environmental simulation. By using environmental simulation, the park can freely switch seasons (spring, summer, autumn, winter), time (morning, noon, dusk, night), weather (sunny, lightning, snow, rain, cloudy). At the same time, by docking with the weather system, the environment simulation content can be automatically switched according to the actual weather data.
Building switching
Click the building switching function on the panel to realize the free switching and jumping between regions and buildings in the park, so that the park managers can find the required buildings more quickly.
Effect of wire frame
Double-click the buildings in the park, you can switch to the wire-frame model. Through the division of regional boundaries and animated display, the regional distribution of buildings in the park is clear at a glance. In addition, the functional division of the building floor is marked in the form of buoys on the building building, and the interior view of the corresponding floor can be accessed through interaction.
Scene digital twin
The layout of the wall on this floor is divided (such as administrative room, financial room, meeting room, etc.), and 3d modeling is carried out for scenes that need to restore the scene environment. In this case, the Internet Data Center (IDC) is used as a reference to model the equipment room, desks and chairs, and large screens. The onsite environment is simulated and restored based on actual locations. Combined with HT digital twinning, the model is not only visible, but also interactive and communicative, so as to carry out visual management of park assets, improve operation management level, and achieve the purpose of reducing cost and increasing efficiency.
Video fusion
HT supports video fusion, which integrates 2D video images into 3D models of scenes, providing intuitive video images and simple view control. Through the indoor surveillance video and three-dimensional scene superimposed display, can be as immersive view of the scene. Advanced functions such as automatic video inspection of critical path and fast target locking in key areas can be realized, providing intuitive and accurate assistance for daily management and emergency handling.
Business functions
The overview
As an important part of the park, enterprises and employees are integrated with HT 3D visualization and park management system, and the management data of enterprises in the park is connected to the visualization platform, so as to update the total number of employees, enterprises and production area in real time. Through the newly settled enterprises in the past two years to the broken line chart, bar chart display, can intuitively compare the investment situation in the past two years. The classification of enterprise industry type statistics, through the data for the next investment plan to provide data reference.
Water data
The water affairs in the park adopts online monitoring equipment to perceive the water consumption in real time. HT 3D visualization system is used to mark the specific points of each water affairs equipment in the form of modeling in the 3D scene, and update the running status and maintenance status in real time through the data panel on the top of the equipment. Combined with the water data on the left side, the park managers have a more intuitive understanding of the water consumption situation in the park.
Distribution data
As a place where enterprises and talents gather, electricity management in the park is particularly important. By accessing the power system data of the park, the power consumption data of the park is connected to the 3D visualization platform, and the power consumption of the park, buildings and enterprises is displayed in the form of data panels. 3d modeling and simulation restoration can be carried out for the layout of the power distribution room and equipment in the park. Data binding points are used to map the data to the equipment model one by one. The current operating status of the equipment can be clearly viewed through the interaction with the equipment.
Parking management
In recent years, with the increase of domestic motor vehicle ownership year by year, traffic and parking in the park have been included in the key planning content, and intelligent parking has begun to appear in the public eye. Through docking parking system data, the original boring data is moved to the visual page in a way that makes people’s eyes shine, so that the parking space usage, parking revenue, vehicle information can be seen intuitively. By displaying the number of remaining parking Spaces in each parking lot in the park in a THREE-DIMENSIONAL scene, it can be clearly judged which area is tight or abundant for parking Spaces, so that park managers can provide an effective decision basis for overall parking planning.
As an important part of the traffic organization in the park, vehicle flow line is mainly reflected in the vehicle traffic planning in the park, and vehicles entering and leaving the parking lot. Reasonable route planning can make the traffic in the park more smooth, on the contrary, the intersection of traffic is prone to traffic congestion. Combined with HT 3D visual rendering engine, vehicle flow lines are displayed as flow arrow animations in 3d scenes, and the traffic organization planning of the park can be clearly understood through the flow direction of the overall vehicle flow lines.
The pedestrian management
The park, as a place with frequent personnel flow, displays statistics and real-time alarms in the form of data panels through access control, face monitoring and other security equipment data. Click the access control icon in the scene to display the face monitoring comparison information of access control personnel. When an alarm occurs, the device interconnects with the onsite access control device in real time and displays the alarm information at the corresponding access control point on the map to remind related personnel to handle the alarm, improving the timely handling rate of alarm events.
Security management
Unified access to the multi-system data visualization platform, through the data panel, can clearly understand the security personnel on duty arrangement and security equipment, monitoring and other operating conditions, real-time grasp of the security dynamic in the park. When the security equipment fails or runs abnormally, the equipment will be highlighted with dyeing and animation alarm diffusion effect to remind the security personnel to deal with it.
Video monitoring
Through interconnection with the monitoring data in the park, the monitoring data is integrated into the HT visual platform to display the real-time monitoring operation in the park. Display monitoring device ICONS according to the actual monitoring points in the 3D scene. Click interaction to view the real-time picture of the corresponding monitoring device. Combine the monitoring point information in the 3D scene, so that users can have a comprehensive understanding of the monitoring points in the park.
The work order system
Access to the park work order system, through the data-driven way, replace the traditional personnel report and feedback mechanism. The work order task is matched with the processing personnel to dispatch personnel to handle the emergency alarm timely, ensuring the timeliness of emergency alarm handling.
HT visualization platform can realize real-time positioning and moving track of processing personnel in 3D scene by using real-time location information of personnel provided, and display the whole processing process of work order in a visual form.
Combined with the contents displayed in the data panel, data analysis was carried out on the work order evaluation and completion to improve the control of the overall work order processing.
The emergency response plan
Save for rain and dig not a well when you are thirsty. For the management of the park, emergency plan is indispensable. A good emergency plan is helpful to identify risks and hidden dangers, understand the occurrence mechanism of emergencies, clarify the scope and system of emergency rescue, so that all links of emergency response and disposal can be followed by rules.
Traditional plans are mostly words combined with pictures, which is difficult to simulate emergency scenarios. Through the integration of HT 3D visualization technology, the plan is restored and simulated in the form of 3D animation. From the occurrence of emergency events to the planning of evacuation routes and rescue routes, users can have a more intuitive understanding of the plan, so as to clear the disposal mode of each link.
