Why use a distributed fiber optic temperature measurement system

Why use a distributed fiber optic temperature measurement system

Cables have strict product standards and requirements, but they are widely distributed. Once the temperature of the cable is locally too high, it can cause a fire, which is extremely harmful. Saboda haka, temperature sensors need to be used to measure the temperature of the cable in operation. Daban-daban, busurs, USB gidajen, and electrical equipment connectors inside the equipment are prone to poor contact and abnormal plug-in eccentricity.

The composition of a distributed fiber optic temperature measurement system

This includes a distributed fiber optic temperature measurement device, ground workstation, and temperature sensing optical cable. The distributed fiber optic temperature measurement device adopts a distributed temperature measurement host setting. The distributed temperature measurement host includes an optical signal generation module, a backscatter signal module, a spectral analysis module, an optoelectronic replacement module, a signal amplification module, a signal acquisition module, a signal processing module, an information display module, an audio-visual alarm module, and a multi-channel interface module. The distributed temperature measurement host is located inside the substation, and the temperature sensing optical cable is laid in an L-shape. The workstation is equipped with a monitoring server.

The distributed fiber optic temperature measurement system can perform real-time, continuous, and large-scale temperature monitoring on key fire prone areas such as cables and substations, achieving the purpose of fire prediction and early warning, and effectively preventing the occurrence of fires.

The functions of a distributed fiber optic temperature measurement system

1. Collection function: Real time, continuous, and large-scale environmental temperature monitoring;

2. Analysis function: It has the function of accurately detecting the trend of temperature changes in the on-site environment, the temperature of key points of mechanical and electrical equipment, and achieving fire warning in key locations;

3. Alarm linkage function: It can send alarm signals and output relevant linkage signals based on the pre-set alarm value of the temperature in the alarm area;

4. On site display function: The temperature measurement host is equipped with a LCD display screen, and real-time temperature and other parameters of each measuring point can be queried underground;

5. Historical data storage and query function: equipped with measurement point historical data, abnormal alarm record storage and query function;

6. Fault diagnosis function: When the temperature sensing optical cable breaks due to external pressure, the system can automatically detect the position of the break point;

7. Networking function: Equipped with network interfaces and standard protocols, it is easy to connect to the mine automation platform and other subsystems.

Characteristics of Distributed Fiber Optic Temperature Measurement System

1. Wide monitoring range: Temperature sensing optical cables are both signal transmission channels and sensors. Temperature values at every point along the cable can be monitored by the temperature sensing optical cable, with real-time, continuous, and wide range temperature monitoring;

2. Rich alarm functions: The alarm zones can be set arbitrarily according to changes in on-site conditions, and each zone can set different alarm values; Maximum value and temperature rise rate alarm modes can be set, and multi-level warning can be set to achieve early warning before a fire occurs;

3. Intrinsic safety: Using temperature sensing optical cables as sensors, no power supply required, intrinsic safety;

4. Friendly human-machine interface: The temperature values of each measuring point can be queried on site.
