Sewage Treatment Network Solution Of Industrial Network Switch

The contradiction among the shortage of water resources, the severe situation of water pollution control, the continuous growth of the national economy and the gradual improvement of the people's living standard in China has become increasingly prominent. Water pollution and water resource shortage have become serious constraints to the sustainable development of China's economy and society. The state and government have also successively introduced a number of measures and policies to encourage the development of the environmental protection industry. The 18th National Congress of the Communist Party of China put forward the new concept of "ecological civilization" and "beautiful China".

The attention and support of the state to the environmental protection industry has been continuously enhanced, and the sewage treatment industry has also been developing rapidly. In the future, with the accelerating pace of urbanization in China and the deepening of environmental protection and water pollution prevention and control actions, the process of establishing a comprehensive and all basin sewage treatment system will be inevitable, and the sewage treatment industry still has a lot of room for development.

The urban sewage treatment project is a sewage treatment system for centralized collection, transmission, treatment and discharge of domestic sewage and industrial wastewater (qualified wastewater), including the urban sewage centralized discharge pipe network (implemented by each county and city), transmission pipeline, sewage pump station along the way, sewage treatment plant, discharge outlet, system monitoring and control center, etc.

The sewage treatment objects include mud and water. The mud is mainly discharged through sedimentation, and the water is discharged after sufficient treatment. The sewage treatment process mainly includes five basic processes: water inflow, sedimentation, reaction, water outflow and idle, which constitute a cycle from sewage entering to the end of idle.

Due to the long distance between the stations in the sewage treatment project and the great impact of the external environment, the requirements for the communication capability and stability of the network equipment are high, so the industrial network switch has been increasingly widely applied to the communication transmission layer in this field. In order to meet the requirements of automatic control in sewage treatment, we choose redundant industrial network switches with high performance and high reliability to form redundant ring networks.

The sewage treatment network scheme of our Industrial Network Switch has the following characteristics:

1. The industrial network switch has large bandwidth and fast transmission speed. The overall scheme adopts full duplex 1000Mbps optical fiber Ethernet ring network.

2. The on-site industrial network switch equipment has the ability to work in a wide temperature environment of - 40~85 ℃, and can adapt to various harsh environments;

3. Industrial network switch industrial ring network design, ring network self-healing time ≤ 20ms, when communication failure occurs, data will be transmitted along the redundant link, improving network redundancy and reliability;

4. The industrial network switch equipment involved in this scheme adopts redundant dual power input design. When one power supply is cut off due to human or natural factors, the other power supply continues to work normally, without affecting the data transmission of the communication system;

5. Network scalability. Compared with field bus, Ethernet has downward compatibility. For twisted pair or optical fiber media, if the transmission speed is increased from 1000Mbps to 10000Mbps, the existing cabling does not need to be changed in most cases, just the network equipment can be updated.

6. Modular design of industrial network switch, flexible configuration of electrical ports and optical ports

7. Support optical fiber interface, with long-distance transmission capability

8. The industrial network switch has a built-in WEB based network management interface to facilitate remote management and maintenance of the network

Summary: The industrial network switch adapts to the requirements of wide temperature range. The power supply adopts redundant power backup and port alarm settings, which greatly improves the reliability and maintainability of the Industrial Switch. The industrial Ethernet network is arranged through the industrial network switch, and the collected data is directly transmitted through the industrial Ethernet. Its IP data can directly communicate with any authorized computer connected to the Internet through the Internet, which can ensure the unified monitoring and management of all sewage treatment in a city in the monitoring center.
