分布式光纤母线槽温度监测系统

Why does the bus duct need temperature measurement
Closed busbar trunking (abbreviated as busbar trunking) is widely used in power supply systems of high-rise buildings and buildings. But with the rapid increase in electricity consumption, the heating of the bus duct is particularly severe, especially at the connection head, which seriously affects the normal operation of the bus duct and requires real-time monitoring of electricity safety. Traditional temperature sensing cables have serious defects in the setting, quantification, 定位, and reusability of temperature alarm points, which cannot meet the needs of production process management. 然而, high-precision point type thermometers or thermocouples cannot solve the needs of linear and continuous monitoring.

What are the advantages of distributed fiber optic temperature measurement systems
The distributed fiber optic temperature monitoring system adopts a brand new design, with good performance indicators and system stability. This system is developed based on the principles of backward Raman scattering and optical time-domain reflection (OTDR的) 定位, and has functions such as optical signal generation, spectral analysis, photoelectric conversion, signal amplification, and processing. The system uses dedicated temperature sensing optical cables as temperature sensors, integrating computer, 光纤通信, 光纤传感, optoelectronic control and other technologies. It has inherent safety, 耐腐蚀性, and is not affected by electromagnetic interference. It continuously monitors long-distance and large-scale environmental temperature information.

Distributed fiber optic temperature measurement software interface

Provide a user-friendly and easy-to-use fiber optic temperature monitoring application software. 软件主要包括温度监控等功能模块, 火警, 和视觉显示.

温度曲线显示

系统可实时显示整条光缆的温度分布曲线, 以及某个位置温度异常时, 该曲线可以显示该位置的温度是升高还是降低.

Historical temperature statistics

Provide historical temperature data statistical analysis function, provide temperature change trends, 包括:
(1) The temperature distribution curve at different positions of the cable at a certain moment;
(2) The temperature change curve of a cable at a certain point on a certain day;
(3) The temperature change curve at a certain point of the cable during a certain period of time;
(4) The curve of the highest temperature change on a certain day.

Over temperature alarm

Provide various flexible fire alarm methods such as fixed temperature, temperature rise, and regional temperature difference, and the alarm parameters can be graded and set by region. When the measured temperature exceeds the threshold temperature, the system will automatically emit alarm signals such as sound, LED indicator lights, text, and images. If multi-level temperature alarm (例如初始警报 30 °C, pre alarm at 40 °C, 以及采取的措施 50 °C) and temperature rise rate can be set, temperature correction can be made according to different environments. The set value of temperature rise rate can be determined by on-site monitoring.

Visual interface

Provide a visual display interface that maps the fiber optic position to the image through a graphical configuration module. Once a temperature anomaly occurs at a certain point of the fiber optic, the alarm information is directly displayed on the image, making it visually appealing.
