Description

Technical Field

[0001] This utility model belongs to the technical field of broadcast alarm equipment, specifically relating to a network-type PAGA system layout structure applied to oil and gas surface engineering. Background Technology

[0002] The PAGA (Public Address and General Alarm) system was initially widely used in industries such as shipping and offshore drilling platforms, especially as an essential communication subsystem in the construction of offshore oil platforms. With technological development and application accumulation, it has gradually expanded its application to industries such as oil and gas surface engineering.

[0003] However, in traditional PAGA systems, the system host and the front-end amplification equipment usually use analog transmission, which requires a separate audio signal cable (analog signal copper cable) for connection. This is not conducive to the flexible application and expansion of the system, and it also increases the construction cost to some extent.

[0004] Furthermore, traditional PAGA system redundancy typically involves deploying two main units, A and B, within the same construction area, without considering the possibility of both main units becoming inoperable if the entire area fails.

[0005] Due to the characteristics of long deployment paths and wide coverage areas of broadcast and alarm equipment in oil and gas surface engineering, the existing PAGA system layout structure is difficult to meet the economic and stability application requirements of oil and gas surface engineering.
