In the field of modern industrial automation, PLC as the core technology increasingly highlights its important position. Especially in tunnel engineering, PLC provides strong technical support for the safe operation of tunnels with its high reliability, flexibility and easy programming.
Multi-dimensional requirements for automation control in tunnelling
In the field of modern industrial automation, the particularities of the changing environment and high safety requirements faced by tunnelling projects place extremely high demands on the automation control system, with systems for ventilation, lighting, monitoring and emergency response requiring precise and reliable control.
PLC's key role in tunnel automation
The use of PLC in tunnel automation can provide the following advantages:
Flexibility:Through programming, the PLC can be easily adapted to the different requirements of tunnel automation.
Efficient:The PLC's real-time processing capability allows it to respond quickly to changes in the tunnel and improve operational efficiency.
Ventilation and air quality control:The PLC is able to operate stably in harsh environments, automatically adjusting the ventilation system according to the level of carbon dioxide and other harmful gases in the tunnel, ensuring the continuity and safety of the system.
Lighting system management:The lighting in the tunnel needs to be intelligently adjusted to the external light conditions and the traffic flow inside the tunnel, where the PLC plays a central role.
Security Monitoring and Emergency Response:The PLC can be connected to surveillance cameras and sensors to monitor the situation in the tunnel in real time and activate preset safety procedures in case of emergency.
Competitiveness and Applicability of Domestic PLC Brands in Tunnel Engineering
Customised adaptations: As the environment, standards and regulatory requirements for domestic tunnels may differ from those abroad, Chinese PLC manufacturers can be more flexible in making customised adaptations to meet the needs of the local market.
Cost-effectiveness: Chinese PLCs are often more competitively priced, which is particularly important in large-scale tunnelling projects.
Technical support and services: Chinese PLC manufacturers are able to respond more quickly to customer needs and provide on-site support, technical support and customised services to ensure the smooth implementation and operation of tunnel projects.
Localised maintenance and upgrades: Tunnel projects usually require long-term maintenance and upgrades, and Chinese PLC manufacturers have more local service centres and spare parts inventories, allowing them to provide maintenance and upgrades more quickly and with less downtime.
Chinese PLC maker empowers tunnel automation
Chinese PLCs have become an important choice for tunnel automation as they continue to improve in terms of technical performance, reliability and price/performance ratio. Chinese PLC brands, such as Unionscience Technology, Hollis, and Nanda Aotuo, have launched solutions for tunnel automation.
Taking Yunnan local enterprises as an example, Unionscience Technology Group, as a leading automation solution provider in China, has rich practical experience in the field of tunnel automation. Through China PLC technology, it has successfully implemented several tunnel projects, demonstrating the advanced and practicality of China PLC technology.
[Case 1] Dali Haidong Intelligent Tunnel Project: As the country's first intelligent landscape tunnel project, Unionscience Technology Group uses self-developed and produced PLC to improve the environment of the traditional long tunnels, and improves the driver's comfort and safety through intelligent control systems.
[Case 2] Kunming Southeast Bypass Expressway Intelligent Traffic and Electromechanical Fire Protection Project: The project covers 13 tunnels, in which the PLC system is responsible for automated control of fire protection, communication, monitoring and other aspects.
[Case 3] Yunnan Provincial Department of Transportation traffic Internet of Things operation monitoring project: Unionscience Technology Group for the Yunnan Provincial highway and waterway safety and emergency management to provide important technical support, its independent research and development, production of PLC plays a central role.
In the technical implementation level, Unionscience Technology Group chose its independent research and development, production of PLC and related supporting hardware equipment, to ensure the efficient and stable operation of the tunnel monitoring system. Through the precise programming and configuration of the PLC system, so that the tunnel mechanical and electrical equipment to achieve synergistic linkage, to achieve a high degree of automation and intelligent target.
Examples of the application of Chinese PLC technology in tunnel automation have fully confirmed its great potential in improving safety performance, optimising operational efficiency and promoting energy saving and emission reduction. The successful practice of Unionscience Technology Group also vividly illustrates how Chinese PLC technology can be effectively used to promote the innovative development of tunnelling projects.
In the future, along with the rapid development of the Internet of Things and big data technology, China's PLC system is expected to achieve a higher level of data analysis and prediction functions, which will greatly improve the safety and operational efficiency of tunnels, and play a more important role in tunnel construction.
