The Best Manufacturing Factory Exporter OEM/ODM Customized for Distributed Fiber Optic Heating Network Pipeline Leakage Monitoring Temperature System-INNO

Functional Characteristics of Distributed Fiber Optic Heat Network Leakage Monitoring System

1. Đo lường phân phối liên tục:
Distributed fiber optic sensors are truly distributed measurements that can continuously obtain measurement information along the detection fiber optic cable for tens of kilometers, giảm đáng kể tỷ lệ báo động sai và báo động sai, và đạt được giám sát thời gian thực.
2. Chống nhiễu điện từ, đạt được tại chỗ không phát hiện điện:
The optical fiber itself is composed of quartz material and is completely electrically insulated; Đồng thời, tín hiệu của cảm biến sợi quang được truyền bởi tín hiệu quang, vốn đã an toàn và không bị ảnh hưởng bởi bất kỳ sự can thiệp nào của môi trường điện từ bên ngoài. It can enter without being charged, thus eliminating the potential danger of electric sparks in areas containing combustible mixed gases, and achieving on-site non electric detection, which is inherently safe.
3. Chống sét nội tại:
Thunder often damages a large number of electrical sensors. Cảm biến sợi quang, do khả năng cách điện hoàn toàn của chúng, có thể chịu được tác động của điện áp cao và dòng điện cao.
4. Khoảng cách đo dài, thích hợp cho việc giám sát từ xa:
The two outstanding advantages of optical fiber are large data transmission volume and low loss. Nó có thể đạt được giám sát từ xa trong hàng chục km mà không cần rơle.
5. High sensitivity and measurement accuracy:
Về lý thuyết, the sensitivity and measurement accuracy of most fiber optic sensors are superior to general sensors, and this has been proven by mature products in practice.
6. tuổi thọ dài, chi phí thấp, và hệ thống đơn giản:
The normal working life of the fiber optic leakage monitoring device exceeds 20 năm. After the completion of a construction project, maintenance free automated operation can be basically achieved, which can greatly reduce the annual operating and maintenance costs of the entire heating project, and achieve the state based maintenance and repair of the heating pipeline.

Distributed optical fibers can be applied in different scenarios, such as pipeline and tunnel leakage monitoring.

The necessity of distributed fiber optic heating network monitoring

In order to ensure the safe and reliable operation of the heating network and to keep track of its operation at all times, it is necessary to set up a monitoring system in the heating network. For directly buried heating networks, some countries have promoted the use of heating network leakage monitoring systems. The leakage of heating pipelines can easily lead to the loss of a large amount of water and heat energy, reducing the transportation efficiency of the heating system. Đồng thời, there are safety hazards in thermal pipelines: due to aging of pipelines, gas and water leaks occur, or due to accumulated water or a large amount of sewage gathering around the thermal pipeline after rain, continuous gasification forms a large amount of steam accumulation, which is difficult to evacuate. There have been varying degrees of thermal pipeline explosions both domestically and internationally.

During the use of thermal pipelines, they will be subjected to high temperatures, mặc, physical and chemical effects, as well as disturbances from surrounding underground engineering construction and ground traffic dynamic loads. Kết quả là, thermal pipelines will gradually develop defects such as cracks, sự biến dạng, and joint damage, leading to accidents such as fractures and leaks. Ngoài ra, the low welding quality between pipe sections, the pressure inside the pipeline exceeding its bearing range, and the corrosion damage of the steel pipe caused by water ingress into the insulation layer also seriously affect the safe operation of the thermal pipeline. Due to the high temperature of the heating medium, emergency rescue is often difficult, and the harm of hot water to other underground public facilities is also significant, making the losses difficult to estimate. Due to the lack of stable and reliable thermal pipeline state detection technology, the existing management mode lacks foresight, and many accidents are only discovered after pipeline damage. Vì thế, it is extremely important for the safe operation of thermal pipelines to take preventive measures and timely grasp the status information of the pipeline.

Đo nhiệt độ sợi quang phân tán technology can continuously and accurately sense the spatial temperature field distribution along the sensing fiber optic, and the sensing fiber used has the advantages of small volume, trọng lượng nhẹ, cấu trúc đơn giản, sử dụng thuận tiện, high pressure and high temperature resistance, và khả năng chống nhiễu điện từ. It provides a new technical means for online temperature and leakage detection of thermal pipelines.
các hệ thống đo nhiệt độ sợi quang phân tán not only has the advantages of ordinary cảm biến sợi quang, but also has the ability to distribute temperature sensing at various points along the fiber optic line. The fiber optic is not only a conductor for transmitting information, but also a sensor for distributed measurement. It can continuously measure the temperature along the fiber optic cable, with a maximum measurement distance of over 20 km. Each continuous temperature sensing segment and spatial positioning accuracy reach a high resolution of 0.4 mét, making it particularly suitable for applications that require large-scale and continuous temperature measurement.
