2) הגדר מערכת אזעקת איתות יומית לניהול הבטיחות היומיומי של אזור המיכל.
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, ספק כוח, 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, ונזק אנושי. 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. לכן, 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, מקוון, and multi-point מערכת למדידת טמפרטורה בסיב אופטי, 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, כלומר, 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, ודרישות ביצועים, and provide a network with good survivability and strong fault tolerance.
