business background

The paper industry is one of the industries with severe environmental pollution due to high energy and material consumption. The papermaking industry has a large amount of wastewater discharge, high concentrations of SS and COD in the wastewater, and many fiber suspended matter, which has brought great harm to the environment and human health. Most papermaking enterprises have some difficulties in wastewater treatment due to the high cost of wastewater treatment, manual inspection equipment, and untimely failures.


In response to these problems encountered by enterprises, Wutong Broadlink has developed a papermaking wastewater treatment system based on PLC remote monitoring. Connect with PLC or other controllers of various equipments through the Wutong Bolian Industrial Intelligent Gateway, and collect data to the cloud of Wutong Paperlink wastewater treatment system through various communication methods such as WIFI, 3G / 4G, Ethernet wired connection On the upper computer such as platform or configuration software, PLC remote monitoring is realized, and the on-site conditions are understood through the cloud platform or monitoring software, which makes the processing process more scientific and reasonable, and improves work efficiency and quality.

System functions

1 Device access, supports access of hundreds of thousands or millions of devices, and provides secure and reliable data processing capabilities, facilitating the security standard access and big data aggregation of various devices.

2 Equipment configuration, set the normal range of status values, when it is out of range, it will be an abnormal state, set the alarm level, alarm time limit and alarm method (SMS, email, internal alarm) of the abnormal state.

3 The gateway adopts various communication methods such as WIFI, Ethernet, 3G / 4G, etc., which is suitable for various use occasions of the equipment.

4 Equipment alarm. The system detects that the equipment has an abnormal status, and obtains the alarm level, alarm time limit, and alarm mode to initiate an alarm notification.

5 Device status query and control, including real-time and historical status query of the device, sending control commands to the device and returning results.

6 Support PLC program remote upload and download, users can remotely program and debug the device.

7 Device access permission control. You can set permissions to restrict user access to the device.

8 Platform access can be provided in the form of monitoring walls, PCs, and various mobile terminal devices.

9 Multi-dimensional report query analysis, various chart displays, and big data analysis provide reference for decision-making.

The application of PLC remote monitoring in the papermaking wastewater treatment system can help enterprises establish a complete remote intelligent monitoring system for equipment, and solve the problem of centralized management and maintenance and fault diagnosis of equipment that is too scattered.
