Application of Cables in Vehicle Safety Monitoring Systems
1.Scene Introduction
With the rapid development of rail transportation technology, the vehicle safety monitoring system plays an increasingly important role in ensuring the safety of train operation and enhancing operational efficiency. The system realizes all-round monitoring of vehicle status, operating environment and passenger safety by integrating various sensors, cameras and communication devices. As the link connecting each monitoring component, the safety and stability of cables are directly related to the normal operation of the whole monitoring system. Therefore, a professional cable solution for rail transit vehicle safety monitoring system has become an urgent need in the industry.
2.The pain point analysis
In the existing rail transit vehicle safety monitoring system, there are the following pain points in the cable:
Unstable signal transmission: Due to the complex and changing environment of train operation, cables are susceptible to electromagnetic interference, vibration and other factors when transmitting monitoring signals, resulting in signal distortion or interruption.
Insufficient reliability: as a key component of the monitoring system, the quality and reliability of the cable directly affects the stability and safety of the entire system. However, some of the cable products on the market have uneven quality, easy to aging and other issues, bringing potential hazards to vehicle safety.
Installation and maintenance difficulties: due to the limited space inside the train, cable laying and installation is more difficult. At the same time, the maintenance and management of the cable also has certain challenges, the need for professional technical support and regular inspection.
3. The vehicle safety monitoring system on the cable requirements
For the characteristics of vehicle safety monitoring system, the cable needs to meet the following requirements:
Excellent transmission performance: to ensure stable and accurate transmission of monitoring signals to avoid signal distortion or interruption.
High reliability: the cable should have excellent durability and anti-aging properties, and can work stably for a long time in various harsh environments.
Good environmental adaptability: the cable should be able to adapt to high temperature, low temperature, humidity, vibration and other complex environments to ensure stable operation of the system.
4.Certification Standards
To ensure the safety and compliance of the cable, the cable products in the vehicle safety monitoring system solution fully comply with the following certification standards:
CE certification: a mark of compliance with the requirements of the European Union Directive, indicating that the cable meets the requirements of the European Union’s safety, health, environmental protection and other regulations.
RoHS certification: A directive restricting the use of certain hazardous substances, ensuring that the cables are environmentally friendly during production and use.
In addition, our cables meet specific standards for the rail transportation industry, such as IEC 60332 (standard for combustion performance of cables) and EN 50264 (standard for cables for rail transportation), GB/T 2423.1, GB/T 2423.2, IEC 60068-2-1, IEC 60068-2-2, EN 60068-2-1, EN 60068-2-2, etc. to ensure that the cables can be used in the rail transportation industry. 2-2, etc. to ensure the safety and reliability of cables in rail transportation applications.
5. Cable Selection
We recommend the following cable types for the needs of vehicle safety monitoring system:
Low-smoke halogen-free flame-retardant cables: low-smoke, halogen-free, flame-retardant and other characteristics, in the event of a fire can reduce the production of smoke and toxic gases to improve the safety of evacuation.
Shielded cable: adopting multiple shielding structure, effectively suppressing electromagnetic interference and ensuring stable transmission of monitoring signals.
Flexible cable: It has good flexibility and bending performance, adapting to the complex wiring environment inside the train.
