What does DTS DVS DAS distributed fiber optic mean

1 DTS distributed fiber optic temperature measurement system

The distributed fiber optic temperature measurement system can be directly applied to long-distance temperature monitoring such as cable tunnels and oil pipelines.

Fully distributed: DTS distributed fiber optic temperature measurement can detect the complete distributed temperature along the entire fiber optic line in seconds without any omissions.

Long distance monitoring: The distributed fiber optic temperature measurement system of Huaguang Tianrui Optoelectronics can monitor a distance of up to 30KM and customize longer distance temperature measurements.

Strong anti-interference: The temperature measuring optical fiber is composed of quartz, electrically insulated, and is not affected by any electromagnetic interference or emits electromagnetic waves, especially suitable for various complex and strong electrical environments.

Intrinsic safety: The temperature sensing element is a temperature measuring optical fiber, and the average power of the optical signal transmitted internally is at the micro watt level; Intrinsic safety.

Accurate positioning: The positioning accuracy reaches ± 1M.

Quick response: High sensitivity, quick response, and short single channel scanning time.

Easy installation: The analyzer is easy to install and has flexible layout.

2. Distributed fiber optic vibration monitoring system

Visual alarm display

Provide a visual display interface that maps the fiber optic position to the image through a graphical configuration module. Once an intrusion accident occurs at a certain point, the alarm information is directly displayed on the image, making it visual and intuitive

Vibration curve display

The system can display the vibration signal distribution curve of the entire optical cable in real time. When the vibration signal strain at a certain location is abnormal, the real-time information at that location can be displayed through the curve

Zone/Level Event Alarm

Provide multiple flexible alarm methods, and the alarm parameters can be graded and set in different regions

Historical statistical analysis provides statistical analysis functions for historical vibration data, including:

a. Vibration distribution curve of optical cable at different positions at a certain moment

b. Vibration variation curve of optical cable at a certain point during a certain period of time

3. Distributed fiber optic acoustic monitoring

1. Live sound monitoring and restoration

The system can accurately restore the sound information of events around the optical cable. High ability in vibration wave analysis. High analysis accuracy.

2. Artificial intelligence analysis

The system has artificial intelligence analysis function. In the audio analysis section, it can automatically filter out pre specified whitelist events, such as wind, rain, trains passing by, cars passing by, lightning and other interference signals. If an abnormal event occurs, immediately alert and clearly indicate the specific location. At present, the vast majority of warning event models have been established, and the accuracy of event recognition can reach 99%.

3. Multi channel listening without interfering with each other

Restore the audio of the environment where the fiber optic cable is located, and ensure that each sound channel does not interfere with each other.

4. Satellite map early warning management system

Combining with geographic information system GIS, use two-dimensional satellite images as the user's display page. A clear and concise image, with a convenient geographical location for memory and oral communication.

5. Accurate position alarm

Accurate positioning based on customer needs

6. Broken fiber positioning system

By real-time monitoring of the reflected light inside the fiber optic cable, the specific location of the broken fiber can be accurately located, which helps to quickly determine the location of the broken fiber after artificial damage or accidental construction damage to the fiber optic cable, reducing the losses caused by accidents.
