The design of large screen solution in dispatch command center is a comprehensive and technical work, which involves hardware selection, software development, system integration and user experience. The following is a detailed design of a conventional solution, hoping to provide some help to everyone.
一、Design concept and principle
Efficiency: The large screen can quickly display key information and support quick decision-making.
Intuitiveness: The information display is clear and concise, reducing cognitive load.
Real-time: Data is updated in time to ensure the accuracy of command decision-making.
User-centered: Fully understand the workflow and information needs of the commander to ensure that the content displayed on the large screen can directly support the decision-making process
二、Hardware selection
1) Display type
LCD splicing screen: It adopts liquid crystal display technology, which is suitable for long-term use and has high color reproduction, but there will be the influence of splicing.
LED display screen: seamless splicing, high brightness, suitable for large space use, the clarity when viewed at close range is not as high as that of wave crystal display. When choosing, we need to decide according to the actual needs and spatial layout of the command center.
2) Performance indicators
Resolution: Select the appropriate resolution according to actual needs to ensure clear display content.
Brightness and contrast: Select the appropriate brightness and contrast according to the ambient light to avoid reflection or too dark
Refresh rate: Ensure smooth picture without stuttering.
Splicing gap: Select a splicing screen with a smaller gap to ensure the integrity of the picture.
三、Software design
1）Data acquisition and processing
Real-time access to multiple sensors and information systems to obtain comprehensive situation information. Efficiently integrate and intelligently analyze this information to extract valuable information.
2）Data display
Intuitively display the processing results in the form of charts, maps, etc.
Support multi-screen display, screen segmentation, screen roaming, screen overlay and other functions to meet the information display needs in different scenarios
3）Interactive function
Support touch technology, gesture recognition and other methods to achieve fast information switching and query.
The interface design is simple and clear, highlighting key information and avoiding information overload.
四、System integration and testing
1）System integration
Follow the principle of standardization to ensure interface compatibility and data sharing between subsystems.
Combine display screen, signal source, screen switching matrix and large screen control software and other components organically to form an efficient and stable information display platform.
2）System test
Carry out comprehensive system testing, including functional testing, performance testing, safety testing, etc.
Optimize and adjust the system according to actual conditions to achieve the best use effect.
五、Application scenarios and functional modes
1）Application scenarios
Traffic command center: real-time monitoring of traffic flow, accident handling, signal light control, etc.
Public security command center: monitor key areas, dispatch police force, and handle emergencies.
Emergency command center: command and dispatch in natural disasters, public health events, etc.
Energy monitoring center: monitor the operating status of energy facilities such as electricity, oil, and natural gas.
Enterprise monitoring center: used to monitor production lines, warehousing, logistics and other links.
2）Functional mode
On-site command and dispatch mode: realize real-time response to abnormal events on site, and promptly handle and solve problems in production or management processes.
Analysis mode: realize phased data analysis and form visual comparative analysis charts to provide a basis for leadership decision-making.
Video monitoring mode: view monitoring images in real time.
Visiting demonstration mode: realize interface carousel and alarm automatic pop-up window, automatic disappearance after resolution, for use during visits.
六、Post-maintenance and upgrade
Maintenance convenience: select hardware and software systems that are easy to maintain to reduce post-maintenance costs.
Scalability: consider possible future expansion needs and choose a system architecture that supports flexible expansion.
Technical support and service: select a fully qualified manufacturer or supplier to provide timely technical support and services.
In general, the design of the large-screen solution for the dispatching command center needs to comprehensively consider multiple aspects, including design concepts, hardware selection, software design, system integration and testing, application scenarios and functional modes, and post-maintenance and upgrades. Through scientific and reasonable design and implementation, an efficient, stable and intuitive command and dispatch platform can be built to provide strong support for various emergency command and daily management work.
