In 2017, DEAN Technology passed the qualification review of the Beijing Municipal Commission of Transport and participated in a research project focused on the operation and maintenance support system for electric buses
As part of the project, research was conducted into the application of distributed fiber optic temperature sensingto trolleybus power supply systems.
The research was intended to explore how distributed temperature sensing technology could support the monitoring and maintenance of electric public transportation power infrastructure.
Reliable electrical infrastructure is essential to the safe and continuous operation of trolleybus systems.
Temperature monitoring can provide useful information about the condition of electrical equipment and help identify abnormal thermal conditions that may require inspection or maintenance.
The research project therefore focused on applying distributed fiber optic temperature sensing technology to trolleybus power supply systems. 德安科技
Unlike conventional temperature monitoring based only on individual measurement points, distributed temperature sensing uses optical fiber as a continuous sensing medium, enabling temperature conditions to be monitored along an extended route.
This makes the technology particularly relevant to electrical and transportation infrastructure where continuous temperature monitoring may be required across distributed assets.
Distributed Temperature Sensing (DTS) uses optical fiber to measure temperature along the sensing route.
Depending on system design and project requirements, DTS can be applied to continuous temperature monitoring across infrastructure such as:
Power cables and cable routes
Electrical distribution systems
Transportation power supply infrastructure
Bus ducts and busbars
Tunnels and other linear infrastructure
Industrial electrical systems
The passive optical sensing medium also makes fiber optic sensing particularly useful in environments where electromagnetic interference may be an important consideration.
At the time of the January 2018 announcement, the research results were expected to be released during 2018 and gradually implemented in trolleybus applications. 德安科技
The project represented an effort to evaluate distributed fiber optic temperature sensing technology under the practical operation and maintenance requirements of electric public transportation infrastructure.
DEAN Technology has continued to develop fiber optic sensing technologies for temperature monitoring across power, transportation, industrial, and other critical infrastructure applications.
