How to realize network segment isolation and cross-network segment access of multiple sewage treatment PLCs
As wastewater treatment plants become larger, more and more devices may be connected to the site. These equipment need to be connected to the automatic control system one by one to achieve digital management, which can effectively improve the efficiency of sewage treatment and reduce operating costs. However, the following problems are often encountered: the IP of the new device cannot be modified and cannot be connected to the network; Devices in different network segments cannot communicate with each other, and device management is difficult. IP conflicts make network planning and management difficult; Cyberattacks can lead to data breaches.

Online monitoring system solution for water, rain and water level in flood storage and detention areas
Flood storage and detention areas are an important part of China's flood defense system. They are low-lying areas and lakes outside river embankments that temporarily store floodwater. It plays an important role in ensuring the safety of production and life in the areas along the river.
In meteorological disasters such as heavy rain and floods, dikes and pumping stations can effectively reduce the pressure of flood storage and ensure timely water storage and timely discharge. The facility is operating normally. In this regard, Wutong Bolian provides an efficient and stable data collection gateway to help monitor water, rain and water level data in real time, enhance the management and early warning capabilities of flood storage and detention areas, and protect the surrounding areas from disasters.
Water level online monitoring system function
1. Data collection: connect the gateway with the rain gauge, flow meter, water level meter and other equipment of each weather station, collect real-time rainfall, runoff, real-time water level and other data, and transmit it to the cloud platform monitoring through the wireless network.
2. Over-limit alarm: When the data such as rainfall, flow, water level, and flow rate exceed the threshold, the system will automatically notify the management personnel through WeChat, SMS, email, etc., and inform the alarm point and alarm point information.
3. Remote monitoring: on-site information and data changes can also be viewed through mobile phones or computers, and multi-terminal data sharing is convenient for managers at all levels to understand the information.
4. Data analysis: Through hydrological data, pumping station operation efficiency and other data, rainwater disasters can be quickly judged, and the carrying capacity of flood storage and detention areas can be understood and scientific decisions can be made in time.

How to implement cross-network segment access and network segment isolation of multiple smart water devices
In the water system, a variety of industrial equipment is usually deployed on site, such as PLC, water pump, sewage treatment equipment, etc., which may be in different network segments, unable to communicate and interact with each other, affecting data integration and network management. This is one of the issues that plagues the digital transformation of enterprises.
How do I achieve cross-segment access and network segment isolation?
It can be implemented through IoT-Bolian NAT translation gateway (network segment isolator). The network segment isolator is suitable for network communication and data acquisition in production networks such as PLC, HMI, CNC, DCS, MES, etc., with cross-network segment isolation and IP conversion functions.
Support network segment isolation and NAT translation of more than 4 devices (such as PLC, CNC, etc.) at the same time; If there are multiple devices in the workshop, if they have IP addresses of different network segments, they can be unified into the IP addresses of the same network segment, and cross-network segment access such as online programming, data transmission collection, and remote management of equipment (PLC, CNC and other CNC) can be carried out.
Through network segment isolation, you can improve the access and communication capabilities between different network segments while maintaining the original network foundation, so as to avoid potential network attacks and data leaks. In addition, network segment isolation can also divide network IP into simpler management units, making network management more concise and efficient. Administrators can more easily configure, monitor, and maintain devices under different network segments, reducing the complexity of troubleshooting and management.
(1) Solve the problem that the IP address of the newly purchased device cannot be modified and cannot be connected to the network
(2) Through NAT translation, solve the problem that devices in different network segments cannot communicate
(3) Through IP renaming, realize unified IP planning and management of production networks
(4) Through IP renaming, solve the problem of hiding the real IP of the device and preventing network attacks
