Background
Recently, the ideology of “lucid waters and lush mountains are invaluable assets” were widely emphasized all over the country. In order to further deepen the ecological civilization and green development, the IoT based environment monitoring system were widely deployed in major cities of China. As an “eye” of ecological and environmental departments to supervise the pollution of factories, Bivocom’s IoT based Environment Automatic Monitoring and Supervision System for Pollution Source makes full use of real-time perception, big data analysis, AI intelligent processing technology and other functions for the whole process of pollution production, control and sewage to realize automatic monitoring, collection, treatment, transmission and analysis of pollution sources. And it has helped optimize and improve the ecological and environmental quality monitoring network, and raised the level of pollution control in scientific and precise way.
System Solution
Bivocom’s IoT based Environment Monitoring and Supervision System consists of 3 layers, the sensing, transport and platform layer.
Sensing Layer:
The sensing layer mainly consists of industrial cellular IoT edge gateway TG462 and various sensor devices. Under the connection of Bivocom’s industrial cellular IoT edge gateway TG462, as the bridge of information exchange, sensing layer can realize the real-time sensor data collection, fast transmission, telecommunication, efficient analysis of pollution source, such as CO2, Flow meter, water quality detector, ammonia nitrogen, temperature and humidity, noise, PH, particulate matter, etc.
Transport Layer:
It connects to the provincial pollution source automatic monitoring platform through the 5G/4G/LTE-M/NB-IoT, wired, wireless, WiFi and other methods that come with theindustrial cellular IoT edge gateway TG462, and provides a network foundation for information sharing.
Platform Layer:
Bivocom’s Pollution Source Automatic Monitoring Platform supports both PC and mobile terminals, which can visually display pollution online monitoring data, with unified supervision, remote control, real-time data query, historical data export, data upload, data abnormality alarm, full display of LED display screen.
Production Recommendation
As the core data transmission device of the pollution source automatic monitoring system, Bivocom’s TG462 has rich I/O to support diverse sensors, including air pollution sources, such as sulfur dioxide, hydrocarbons, particulate matter, carbon monoxide, hydrogen chloride, VOCs, and wastewater pollution sources, such as COD, ammonia nitrogen, total phosphorus, PH, etc. And all the data of field sensors will be collected, transferred to remote IoT platform, to realize real time data collection, monitoring, analysis remotely.
Real-time Monitoring
24-hour real-time monitoring of water quality parameters such as PH value, oxygen content, ammonia nitrogen, total phosphorus, chemical oxygen demand, as well as air pollution source parameters such as sulfur dioxide, hydrocarbons, particulate matter, carbon monoxide, hydrogen chloride, effectively realize the prevention and control of pollution source events.
Real-time Alarm
The standard and maximum value of all kinds of sensors were set at the site of pollution sources. Once the certain value is exceeded, the alarm will be timely reported to the users through message, wechat, telephone and other means.
Remote Control
Remote control is carried out on each monitoring site according to existing communication protocols, that is, basic operations such as adding, modifying, checking, and deleting pollution source information data, so as to standardize and manage all on-site devices in a unified manner.
IoT Based Environment Monitoring Platform Function
Visual Analysis
Annual, monthly and daily reports can be generated for water quality, atmosphere, noise and other data at the site of pollution sources, and statistical analysis, benchmarking reference, etc. Managers can carry out visual analysis through the comprehensive display of the platform, and manage the real-time data and the working status of the staff remotely.
Real-time View
The platform adopts the form of real-time data table and real-time graph, and the monitoring interface is clear and intuitive, supporting the setting of real-time data refresh frequency, and can generate annual, monthly and daily reports for the water quality, atmosphere, noise and other data of the pollution source site, and carry out statistical analysis and benchmarking reference. Through the comprehensive display of the platform, the management personnel can remotely manage the real-time data of the site and the working status of the staff.
Audio-visual Alarm
The alarm bar is automatically refreshed. When a new alarm is generated, an audible and visual prompt is displayed. The system automatically records the handling methods of on-site pollution source alarms and tracks the handling results.
