Preface

Under the upsurge of digital economy driven by "new infrastructure", the development of smart parks has become the core starting point for realizing green, modern and intelligent park management. By using new-generation technologies such as cloud computing, Internet of Things, and big data, it can fully aggregate various resources in the park, comprehensively improve the comprehensive management efficiency of the park, and open up the dynamic perception, real-time sharing, Efficient application.

Hightopo applied self-developed HT products, seamlessly integrated 2D and 3D technologies, and built a lightweight 3D visual smart park management and control system. Focusing on public management, industrial development, life services and other businesses, it provides functions such as energy consumption and environmental monitoring, equipment security supervision, comprehensive situation monitoring, etc., so that the original independent systems in the park can form a linkage plan according to the management characteristics, which can be widely used in industrial parks, Scenarios such as government communities and campus operations.

effect display

The home panel information collects the summary of various monitoring information in the park. Based on the three-dimensional scene, the virtual simulation technology is used to reproduce the buildings, facilities, pipelines and gardens in an all-round way. The initialized scene can roam the park in a panoramic view. The powerful rendering capability of the engine ensures that the scene can be loaded and run efficiently and smoothly in the Web and the excellent visualization of the scene, as if being in a real campus environment.

Create the internal management and control module of the park property, and integrate the data and information of the property personnel, which can meet the management requirements of easily responding to daily duty. Double-click the building serial number to display the operation and maintenance details, on-duty information, and responsible person information of the corresponding building. You can customize the on-duty personnel information to provide information support for managers to conduct personnel scheduling and command. While improving the enterprise service awareness, it also improves the efficiency of cross-department and cross-level communication, so that all employees can achieve collaborative work and industrial management through the network.

Double-click the park building, switch to the wireframe model, achieve a transparent building appearance, divide the area through the boundary, supplement it with animation display, and mark the corresponding floor function in the form of a buoy next to the building to visually check the overall layout of the equipment. The layout of the building is clear.

System Analysis

Hydropower consumption monitoring

With the proposed carbon neutrality goal, the park plays a very important role in how to systematically and scientifically manage and guide enterprises to reduce carbon and green development. The so-called "carbon neutral" park refers to the total amount of greenhouse gas emissions directly or indirectly generated within the scope of the park's accounting, comprehensive utilization of energy saving, emission reduction, carbon sequestration and other methods within a certain period of time, through industrial green transformation, resource Recycling utilization, agglomeration and sharing of facilities, and self-balancing of carbon emission and absorption are basically achieved within the park. To achieve a “carbon neutral” park, it is necessary to formulate a specific emission reduction strategy and clarify the park’s carbon accounting system, such as the scope of carbon accounting, emission sources, and forms of accounting and monitoring.

The HT hydropower energy consumption monitoring module integrates dynamic energy efficiency environmental data such as water, electricity and coal in the park, and combines the production consumption, sewage, waste and other pollutant discharges in the park to carry out power consumption detection and measurement of lighting, air conditioners, computer rooms, water pump rooms and other facilities. management, energy efficiency analysis and energy conservation management. Supports the selection of different colors to classify energy consumption levels. The brighter the building color, the more energy consumption. When the early warning value is reached, a 2D alarm panel will pop up. The energy consumption trend analysis can be deduced online, the energy consumption process can be traced, and energy consumption loopholes can be found. Managers can Combined with energy-saving diagnostics to improve energy usage.

Smart Elevator

Through the underlying application interface, the obtained information such as the position distribution, status, speed, quality inspection and other information of each elevator can be uploaded synchronously. Follow the elevator carrying logic rules to establish a variety of supervision modes such as flow of people, loads, fireworks, and behavior. In the face of uncivilized elevator rides, the system regulates the safety of people taking the elevator through automatic identification and automatic dissuasion. The emergence of smart elevators drives the scientific management of elevators for fault self-diagnosis, remote control start-stop and predictive maintenance measures, which not only prolongs the service life of elevators, but also reduces the maintenance burden.

When the elevator operation data exceeds the limit, the system will automatically alarm to the relevant departments according to the emergency plan process, and track and playback the fault scene, providing a scientific decision-making basis for the manager's rescue command. Visualized supervision realizes automatic inspection of critical paths, quickly locks key areas, and prevents accidents such as roof jumping, broken ropes, electric shocks, and car crashing to the bottom, laying a solid foundation for efficient and safe operation and maintenance of the park.

Through the HT 2D visualization technology, the operating parameters of the elevators in the park can be switched in a "one-picture" style, and data interpretations of different dimensions can be output. HT visualization technology adopts B/S architecture, supports cross-platform browsing, and can be browsed by any mobile terminal. It provides single-finger rotation, two-finger zoom, and three-finger translation operations of touch screen devices, even if the operation and maintenance personnel are not at the workstation. Monitoring and remote control can be carried out through mobile phones or IPad, and there is no need to worry about different interaction modes across platforms. In turn, the fault response time is shortened, and the elevator can be converted from passive perception to active prevention.

Security Monitoring

In order to improve the security management and control effect of the park, HT supports the seamless integration of various multimedia functions of HTML5, links various security subsystems, and conducts dynamic security monitoring for the whole area such as public, office, and equipment rooms. Automatically locate alarms during behavior, and generate visual demand charts such as emergency plan processing work orders and historical alarm records. Empower managers to carry out process-based, institutionalized, and globalized digital management of security work in the park.

Fire Management Visualization

Fire System

The fire protection system of the building mainly includes fire alarm system, fire hydrant system, automatic sprinkler (sprinkler) fire extinguishing system and evacuation system. The HT 3D visual fire protection module makes full use of various sensors to perform 7*24 intelligent perception, positioning, and identification of key areas and facility operation status. With HT's rich visualization components, various types of information collected are presented on both sides of the panel. On-duty, such as the fire department's duty status, the overall analysis of the fire situation, real-time monitoring data, current alarm records, the operation of various subsystems, and key area scene monitoring, etc.

When an abnormal condition of early warning alarm is received, the system will automatically trigger the fire alarm device, and quickly display a red [warning] in the corresponding scene, so as to inform the manager of the specific location information, and automatically generate a rescue emergency plan based on the analysis and evaluation of the disaster situation. Linked with HT video fusion technology, the actual monitored video image is integrated with the 3D scene, and the original fragmented video can be seen in the real 3D scene panorama, assisting managers to conduct real-time situation awareness and historical data retrospective comparison of the scene and other monitoring needs.

Fire Alarm

In order to improve the overall fire incident statistics and fire status (alarm rate/failure rate/shield rate) records in the park, and to meet the macro-supervision of the park fire resource distribution, security situation, and fire facility status, the HT 2D panel supports binding the Fire-fighting equipment data, such as manual alarms, smoke detectors, the number of alarms, failures, and the total number of equipment in each building, the relatively abstract and complex data is clearly presented through the HT visualization chart, which provides information for fire management work. The remote and efficient supervision and management method ensures the integrity, authenticity and traceability of the fire protection information in the park.

The establishment of the fire alarm function can reflect the current situation of fire protection in the park in a centralized and objective manner, which not only consolidates the supervision of the fire department, but also avoids property losses and casualties caused by out-of-control leaks.

Fire Water System

Fire-fighting water supply system, as a common fire-fighting facility, is very important for fire-fighting, but the previous management forms cannot balance and effectively monitor the operation status of equipment.

The HT scene highlights the route of the laid municipal fire water supply pipe network. Integrate intelligent sensing equipment data to enable it to monitor and control fire water in buildings, and then combine with 2D panels to centrally display key equipment parameters such as fire water pressure, liquid level, temperature and humidity, flow and other key monitoring equipment in the park. It can completely replace manual inspection. Ensure that it is always in a constant and stable predetermined pressure state and has sufficient water volume, so that water can be quickly discharged in the event of a fire.

Promote the intensive development of fire protection and water affairs in the park, ensure the normal operation of facilities, and provide strong support for quickly eliminating hidden dangers and firefighting and disaster relief.

Construction Management

The construction of the park is closely related to the progress of investment promotion and the occupancy of enterprises. Effectively integrate existing resources, divide engineering projects into regions through different color blocks, and reasonably determine the development intensity and scale of land use. Focusing on the whole life cycle of construction projects, establish an information platform that supports on-site management, data sharing, and interconnection and collaboration, focusing on key indicators such as construction period progress, type analysis, project sub-items, and hidden danger statistics, and firmly grasp the “people, Machine, material, method and environment" five elements.

On the one hand, it can meet the flat and grid-based supervision of various business links such as safety, environment, and patrol, and on the other hand, with the help of intelligent means, it can help managers understand the real-time situation in abstract data and reduce the interference of human factors on the construction site. , to achieve digital, refined and green production and management of construction sites.

In this case, the 3D modeling of the details of the buildings and roads in the park is manually performed, and the OBJ format model is output, which is rendered by the HT engine, and the overall layout of the park is simulated and restored. For building information modeling (BIM) requirements, HT provides the function of converting BIM models to HT primitives, which can perform lightweight processing on BIM files. Combined with the powerful rendering capabilities of the HT engine, HT ensures that the scene is efficient and smooth on the Web. Load and run quickly, reducing development costs.

Visual monitoring of pedestrian/vehicle flow

Supports multi-dimensional data such as space, time, and indicators to dynamically refresh the traffic flow, type, and time period analysis data of people and vehicles in the park, and summarize the number of daily visitors to the park in real time, helping managers easily grasp the in and out of the park's pedestrian/vehicle flow. , paving the way for the efficiency of public security management in the park. Establish the threshold alarm trigger rules for people/vehicle flow in the park, and analyze and judge the risk of people/vehicle flow through functions such as personnel gates, vehicle gates, video inspections, and electronic fences. For suspicious persons and vehicles that have been stagnant for too long or crossed the boundary, the system immediately alerts the relevant departments for manual intervention, providing precise positioning, trajectory playback, and dynamic tracking.

All elements regulate and optimize the flow of people/vehicles/goods in and out of the park, prevent risks from external input, and construct an integrated perception system for safety management and comprehensive emergency response.

Floor Scene Visualization

Office area visualization

When the dual carbon policy was implemented, Hightopo actively responded to the call for green buildings and was committed to creating cool, green and new smart office areas. In order to facilitate the unified and coordinated deployment of building floor defense in the property park, the system supports viewing the regional functions, laying display, and company layout information of each floor, and accurately and intuitively records the energy consumption load and electricity usage of each office in the 2D panel. , garbage collection and fire protection facilities status, further refine the basic data of energy operation between floors in the park, helping managers to explore the intrinsic value of information resources.

Cold source equipment room

These devices are in an open working state all the year round, and do not form a closed loop. As long as the power is turned on, the devices start to operate, so that their operating status, process, and energy consumption data cannot be obtained and presented in real time, let alone in-depth improvement and savings. energy.

Through the powerful rendering function of the HT engine, the operation effect of the cooling tower, cold water pump, chiller and condensate pump equipment is truly restored, and different colors are used to distinguish the operation content of each pipeline. It can display the dynamic data of the cooling source equipment in real time, such as the rotation speed, AI prediction value, average speed, load flow rate and other equipment, and simultaneously collect environmental parameters (temperature and humidity), system energy efficiency indicators (machine room COP), system operation data (chilled water temperature difference, classification Multiple indicators such as water heater pressure difference, etc.) and host load are placed in the 2D panel to create multi-parameter real-time monitoring.

The terminal intelligent energy-saving control system is added to realize intelligent adjustment of the air supply temperature, water valve opening and fan frequency inside the building according to changes in temperature and humidity, which not only ensures the comfort of terminal use, but also optimizes the operating state and operating time of the equipment. Reduce energy consumption, extend the service life of equipment, and reduce the workload of maintenance personnel.

Parking lot visualization

Using the HT three-dimensional simulation parking lot scene and accessing the data of the parking lot management system, you can intuitively view the entry and exit, parking, and vacancy of vehicles inside and outside the park, such as visitors and reservations. Support to meet the current development trend of new energy vehicles, according to the actual planning of parking spaces in the parking lot, use HT 3D visualization technology to set up vehicle charging piles in the scene synchronously, show the distribution area of charging piles in the park and whether there are vacancies, and combine 2D panels to display the charging ratio , mileage, power, etc. Help the park to improve access efficiency and user parking experience, and reduce labor management costs.
