Distributed Fiber Optic Temperature Measurement System Oil Storage Tank Spherical Tank Temperature Sensing Fiber Price

The distributed fiber optic temperature measurement system can implement real-time monitoring of the temperature inside and outside the pipes of external floating roof storage tanks, internal floating roof storage tanks, arch roof storage tanks, pressure spherical tanks, external floating roof storage tanks, external floating roof storage tanks, and external floating roof storage tanks.

The entire monitoring system consists of two parts: hardware and software. The hardware part includes four systems, namely: fiber optic sensor system; Data collection system; Data communication and transmission system: data analysis and processing system. The various systems operate through fiber optic network connections.

Fiber optic sensor system

According to the optimization analysis of the overall structural model of the tank farm, the sensors and related accessories that need to be installed in the tank farm include: fiber optic liquid level sensors, distributed fiber optic sensors for pipeline leakage monitoring, distributed fiber optic temperature sensors, as well as signal amplifiers, regulators and other accessories.
data acquisition system
Including data collection stations controlled by microcomputers installed outside the tank area, each collection station is a PC based collection substation. Their main function is to collect data transmitted by fiber optic sensors, perform signal conditioning, perform preliminary data processing and storage, and then transmit it to the data processing and analysis system of the monitoring center. Data communication and transmission system
This includes the establishment of network operating system platforms, sites, network protocols for security monitoring of local area networks, and connections with other local area networks or backbone networks.

Data processing and analysis system
Connect several high-performance workstations to several data collection stations in the tank area to form a computer network. The workstation is a desktop computer installed in the monitoring and management center outside the tank area, and equipped with the required data display software. The workstation realizes data collection and processing, monitoring data display, system control management and maintenance, and security analysis and evaluation.
The real-time monitoring system for the tank farm mainly includes the following functions:
1) Report the current status information of each storage tank, including the items stored in the tank, liquid level, and whether there are leaks.
2) Set up a daily signal alarm system for the daily safety management of the tank area.
3) Monitor fire alarm information in the tank area and conduct preliminary fire alarm handling.

Fiber optic sensor system
The fiber optic measurement unit and fiber optic sensor are installed on site in the tank area, while the photoelectric converter, power supply, and computer system are installed at the data acquisition station, and the two are connected through optical cables.

Distributed fiber optic sensors for pipeline leakage monitoring

Lay a parallel optical cable near the oil and gas pipeline, using optical fibers as sensors to pick up pressure and vibration signals generated by incidents such as oil and gas pipeline leaks, nearby mechanical construction, and human damage. At the light incidence end, locate the losses caused by the above events using an optical time-domain reflectometer; At the optical output end, use an optical power meter to detect changes in optical power and determine the type of event based on signal characteristics. Distributed fiber optic sensors can monitor pipeline leaks. Therefore, laying distributed fiber optic sensors around the pipeline in the tank area can be used for real-time online monitoring of pipeline leaks.

Distributed fiber optic temperature sensing network

The distributed fiber optic temperature sensing network for industrial process detection is a real-time, online, and multi-point fiber optic temperature measurement system, which is a new detection method and technology. The optical fiber in the system is both a transmission medium and a sensing medium. By utilizing the strength of the fiber’s backward Raman scattering, the back Raman scattering photoelectric signal with temperature signal is collected by a wavelength division multiplexer and a photodetector. After signal processing and demodulation, the temperature information is extracted in real-time from noise and displayed. It is a typical laser fiber temperature communication network. It can collect 1000 temperature information and perform spatial positioning on a 2km long optical fiber, and has been applied in the automatic temperature alarm system for tank area fires.

Distributed Fiber Optic Data Communication and Transmission System

The communication between various systems is achieved through all optical communication technology. All optical communication technology is a type of fiber optic communication technology that is improved to address the numerous electronic conversion devices present in ordinary fiber optic systems. This technology ensures that the signal transmission and exchange between users are all carried out using optical wave technology, that is, the transmission process of data from the source node to the destination node is carried out in the optical domain, and its exchange at each network node is carried out using all optical network switching technology.

The all optical communication network consists of an all optical internal part and a general network control part. The internal all optical network is transparent and can accommodate multiple business formats. Network nodes can transparently send or receive from other nodes by selecting appropriate wavelengths. By appropriately configuring wavelength routing optical crossover devices, transparent optical transmission can be extended to larger distances. The external control part can achieve network reconstruction, dynamically allocating wavelengths and capacity throughout the entire network to meet changes in communication, business, and performance requirements, and provide a network with good survivability and strong fault tolerance.
