As a cryogenic liquid, LNG not only needs to be operated in accordance with the regulations, but also must have a complete monitoring system to track and perfect the safety operations. Taking LNG peripheral guard system as an example, the safety monitoring system consists of electronic patrol system, whole plant video surveillance system, access control system and whole plant peripheral guard system. Video surveillance systems have been installed in critical production units and installation areas, such as in critical production sites, where stationary and cloud-based cameras are commonly used. The high performance digital microwave is adopted for the alarm devices outside the factory and intrusion detection, enabling the interaction between the cameras around the walls and the surrounding digital microwave. In the security monitoring system, access control system and electronic patrol system play an important role in daily management and production inspection. Most of the raw materials involved in the production of LNG are flammable and explosive gases and liquids, which are easy to cause fire. In the process of LNG production, with the continuous expansion of the production scale, the safety technology of LNG is constantly mature.
Safety monitoring system is a kind of comprehensive product that covers a variety of disciplines and technology systems. This kind of monitoring technology is applied in combination with reality to fulfil the functional expression of the system, that is, the actual test, and the numerical determination of a series of parameters is realized according to the monitoring results.
