1、 Industry background and demand analysis

The petrochemical industry, as a technology intensive field, has production facilities with characteristics such as high temperature and high pressure, flammability and explosiveness, and toxicity and harm. According to statistics, in 2019, data from the State Administration of Work Safety showed that fires and explosions caused by combustible gas leaks accounted for over 60% of accidents in the petrochemical industry, while poisoning and suffocation accidents caused by toxic gas leaks have long been among the top occupational hazards. With the transformation of the industry towards intelligence and greenness, traditional monitoring methods can no longer meet the requirements of real-time, accuracy, and scalability. Industrial Ethernet technology based on TCP/IP architecture has become the core support for building a gas monitoring system for the entire plant area due to its openness, compatibility, and high-speed transmission capability.

2、 Advantages of TCP/IP architecture technology

1) compatibilityReal time data transmission

By supporting standard protocols such as HTTP, FTP, SMTP, etc., seamless integration of devices from different vendors can be achieved, enabling cross platform data sharingAt the same timedata transmissionThe efficiency is much higher than RS485,A single switch can support 256 detection nodes, with a coverage radius extended to 2 kilometers, meeting the needs of large factory areas.

2) Cost effectiveness and maintainability

Compared to traditional fieldbus, TCP/IP architecture achieves serial device networking through standardized hardware (such as MOXA Nport series serial servers), reducing wiring costs by 30%. The remote management function supports parameter configuration through a web interface or SSH protocol, reducing annual maintenance hours by 400 hours and improving fault location efficiency by 70% for a certain enterprise.
