Remote Monitoring System Solution for Data Collection from Mineral Processing Wastewater Treatment Equipment

The combustion of coal generates a significant amount of flue gas containing SO2. If discharged into the environment without treatment, it will pollute the atmospheric environment and endanger public health. Therefore, it is essential to properly treat these exhaust gases to meet national standards before discharge.

 

Wet desulfurization is a widely used method in coal-fired power plant flue gas desulfurization projects. It primarily involves spraying lime slurry in an absorption tower to react with SO2 in the flue gas, thereby removing SO2. However, this process also introduces the issue of wastewater treatment. Therefore, it is necessary to monitor and manage the wastewater treatment equipment to ensure compliance with wastewater discharge standards. In response, WideIoT provides a configuration monitoring system solution for desulfurization wastewater treatment equipment based on PLC data acquisition gateways.

 

Solution Overview

 

Deploy WideIoT industrial smart gateways in the electrical control cabinets of desulfurization wastewater treatment equipment. These gateways are connected to the controller PLCs and configured with device models, acquisition frequencies, alarm rules, etc. The gateways can then collect real-time operational parameters from the equipment and transmit them to the cloud platform or upper computer via 5G/4G/WIFI/Ethernet, enabling real-time monitoring, fault alarms, management control, and remote maintenance operations. This ensures the safe and stable operation of the equipment and guarantees compliance with wastewater discharge standards.

Implemented Functions

 

Comprehensive Data Acquisition: Achieve full collection of PLC data from wastewater treatment equipment, ensuring that key information such as equipment operational status, working parameters, and alarm data is uploaded to the configuration platform in real-time. The system is compatible with the HJ212 protocol, enabling seamless integration with environmental protection bureau platforms for data sharing and regulatory purposes.

Visualization: Through configuration interface editing, the operational information of wastewater treatment equipment can be visually displayed, including the start/stop status of pumps, valve open/close conditions, inflow and outflow rates, motor operating frequencies, and water quality conditions. This information can be presented in the form of visual data reports or curve graphs.

Alarm Conditions: Set multiple alarm conditions. When abnormal data such as excessive water pressure or low current is detected, the system automatically triggers alarms and notifies relevant personnel promptly through various channels including WeChat, SMS, email, and platform notifications, enabling rapid response and handling of alarm information.

Remote Control: Enable remote writing of control instructions to PLCs, allowing for remote control of pumps, valves, and other operations. This facilitates prompt management and control in case of abnormalities, effectively preventing production accidents and economic losses.

Remote PLC Access: Provide network channels for remote PLC access, enabling remote programming, debugging, and program uploading/downloading operations for PLCs located in different locations. This improves work efficiency and management levels while reducing travel frequency and operational costs.

Comprehensive Analysis: Through comprehensive analysis of factory production efficiency and environmental protection indicators, accurately assess the operational efficiency and risks of wastewater treatment equipment. This provides a solid basis for making scientific and reasonable decisions to ensure the safety of wastewater treatment.

What is an Industrial Gateway?

  In the era of Industry 4.0, where smart factories and interconnected systems dominate,   industrial gateways   have emerged as critical components for enabling seamless communication, data exchange, and automation across diverse industrial environments. But what exactly is an industrial gateway, and why is it indispensable in modern manufacturing and process control? This article explores its definition, functions, types, and real-world applications. Definition of an Industrial Gateway An   industrial gateway   is a specialized hardware or software device designed to bridge communication gaps between incompatible industrial networks, protocols, or devices. It acts as a translator and router, ensuring that data from legacy machinery, sensors, controllers, or cloud platforms can be understood and utilized by other systems. Unlike standard networking gateways, industrial gateways are built to withstand harsh environments (e.g., extreme temperatures, v...

IoT Solution for DCS Data Acquisition of Stackers and Reclaimers

图片
  In thermal power plants, stackers and reclaimers play a crucial role in storing and conveying raw materials. They execute various automated instructions through PLCs (Programmable Logic Controllers) and DCS (Distributed Control Systems), such as allowing stacking, allowing reclaiming, peripheral reclaiming operation, emergency shutdown of stackers and reclaimers, stacking operation, stacking faults, reclaiming faults, reclaiming circuit, and more. These instructions provide reliable assistance for enhancing production efficiency and management levels. To achieve DCS data acquisition and enable remote monitoring and precise management of stacking and reclaiming operations, WideIOT offers an IoT solution based on industrial smart gateways. By connecting to the central control room’s DCS, the gateway can adapt to protocols and perform data acquisition. The collected data is then transmitted to a remote monitoring cloud platform, enabling functions such as visual display, remote moni...

IoT Solution for Digital Transformation in Discrete Manufacturing Industry

图片
  For enterprises aiming to achieve smart manufacturing and digital transformation, the most challenging and core aspect lies in digitizing the production process.  This is particularly true in the discrete manufacturing sector, where products are often assembled from multiple components through a series of discontinuous processes. The production process involves numerous variables and uncertainties, all of which need to be captured and monitored. Taking the automotive manufacturing industry as an example, the production process includes stamping, welding, painting, and final assembly.  The equipment involved ranges from stamping machines, welding robots, painting robots, drying ovens, and assembly robots to ancillary PLCs, sensors, and instrumentation. Data such as temperature, pressure, flow rate, voltage, and current are crucial determinants of a vehicle's quality. In response, WideIOT provides data acquisition gateways that connect to PLCs, instrumenta...
