Distributed fiber optic bus duct temperature monitoring system

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, pagpoposisyon, and reusability of temperature alarm points, which cannot meet the needs of production process management. Gayunpaman, high-precision point type thermometers or thermocouples cannot solve the needs of linear and continuous monitoring.

What are the advantages of ipinamahagi ang fiber optic mga sistema ng pagsukat ng temperatura
Ang 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) pagpoposisyon, and has functions such as optical signal generation, spectral analysis, conversion ng photoelectric, pagpapalakas ng signal, at pagproseso. The system uses dedicated temperature sensing optical cables as temperature sensors, pagsasama ng computer, fiber optic na komunikasyon, fiber optic sensing, optoelectronic control and other technologies. It has inherent safety, paglaban sa kaagnasan, 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. Pangunahing kasama sa software ang mga functional na module tulad ng pagsubaybay sa temperatura, alarma sa sunog, at visual na pagpapakita.

Pagpapakita ng curve ng temperatura

Maaaring ipakita ng system ang real-time na curve ng pamamahagi ng temperatura ng buong optical cable, at kapag may abnormal na temperatura sa isang tiyak na lokasyon, maaaring ipakita ng curve kung tumataas o bumababa ang temperatura sa lokasyong iyon.

Historical temperature statistics

Provide historical temperature data statistical analysis function, provide temperature change trends, kasama ang:
(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, pagtaas ng temperatura, 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 (such as initial alarm at 30 ℃, pre alarm at 40 ℃, and measures taken at 50 ℃) 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.
