Industrial Ring Network Communication Solution
1、Overview
The environment of petroleum refining plants is complex, and high safety monitoring requirements are required. In order to improve the safety monitoring of the flow of people and logistics in the factory area, the safety monitoring system of a certain refinery of PetroChina adopts an industrial switch group ring network.
Characteristics of industrial ring network:
Severe environmental conditions, such as high temperature, low temperature, humidity, dust, and vibration. Under these extreme conditions, the equipment needs to have higher durability and anti-interference ability.
Power supply requirements: In industrial sites, POE technology is required to provide power to certain equipment to reduce the complexity of power lines.
The reliability of the network. In the industrial field, network interruptions may lead to production interruptions, quality issues, and even security risks. To ensure the high reliability and stable operation of industrial grade ring network switch networks, redundant power supplies and hot swapping functions are usually equipped.
Based on the characteristics of the industrial ring network mentioned above, Haishuo proposes an industrial ring network communication solution to effectively meet the development needs of industrial informatization, meet the special needs and challenges of the industrial environment, and ensure the stability, reliability, and security of the network.
2、Plan diagram
For key points, front-end access can be achieved through a rail type industrial switch with a 100Mbps electrical port, and a gigabit optical port can be used to form a gigabit optical ring network, constructing redundant circuits in the ring network. Optional POE for electrical access, which can be connected to and powered by network devices such as network cameras, IP phones, and wireless APs; The computer room uses a rail type industrial switch as the control node to control the links within the control loop and connect to the core switch.
For scattered points, front-end access can be achieved through a rail type industrial switch with a 100Mbps electrical port, and a gigabit optical port can be connected to a convergence switch. The optional POE for electrical port access can be connected to and powered by network devices such as network cameras, IP phones, and wireless APs; The data center uses industrial switches to aggregate front-end data and connects to core switches.
The computer room uses a 24 port gigabit electrical port and a 40000 Mbps optical port switch. The dry Mbps electrical port meets the requirements for local monitoring data transfer and forwarding, while the 10000 Mbps optical port meets the requirements for remote management platforms, allowing units to access monitoring data.
3、Advantages of the plan
1. Super strong anti-interference performance
Industrial switches have strong anti-interference functions, such as high protection levels (IP40) in lightning protection, waterproofing, corrosion prevention, anti-static, etc.
2. Using industrial grade components
Industrial switches have high requirements for the components of their products and can withstand harsh environments. Therefore, they can adapt well to industrial environments and support various industrial applications in harsh environments.
3. Wide temperature operation
The industrial switch adopts a metal shell, which provides better heat dissipation and stronger protection. It can operate normally within the temperature range of -45 to+85C and can adapt to complex temperatures and humidity
Not afraid of severe cold or scorching heat, ensuring stable and uninterrupted high-definition monitoring footage.
4. Fast ring network and fast redundancy
Industrial switches generally have fast ring network and redundancy functions, with a redundancy time of less than 50ms.
5. Redundant power supply design
The industrial switch adopts a dual power redundancy design to ensure stable and reliable operation of the system.
6. Long service life
The industrial switch adopts an industrial grade solution from the shell to the components, so the product has higher reliability and longer service life.
