Problem Analysis

1. The system of sewage treatment is not perfect and the supervision of environmental protection departments is not in place. The problems include the low supervision ability, the lack of professional skills of the supervision personnel, and the imperfect monitoring system.

2. The early-developed chemical industrial park adopted a traditional monitoring method. Its low informatization causes a high cost of monitoring and low efficiency.

3. The emergency plan of the chemical park is not established on the basis of the investigation of enterprise environmental safety hazards and the construction of emergency materials disposal capacity, which lacks scientific and practical.

System Solution

Bivocom provides solution to alleviate the environmental quality problem of chemical industry parks. This solution makes full use of technologies of IoT, cloud computing, big data, etc. Forming an infrastructure smart data network that improves the sensing and early warning management of chemical industry park efficiently. The monitoring solution can monitor, collect, transmit, and warn the data of environmental pollutants, like SO2, NO, NO2, inorganic acid, inorganic and salt mud, etc. in real time. In this way, the environmental quality of industry parks can maintain a good state.

This solution consists of sensing devices, industrial IoT RTU, center server and web system. There is a working process for this system. Firstly, the sensors connect with industrial RTU and collect environmental data of chemical industry parks in real time. Secondly, the data will be sent to the center sever through 5G, WIFI, NB-IoT, etc. Thirdly, the server store and analyze the data. Finally, the app or PC ends will shouw the data which helps managers learn more about the environmental quality state of the park.

Solution Functions

1. Data Monitoring

Real-time display of equipment status, reporting time, wastewater, waste gas, waste slag, and other data reported by the equipment and summarizing statistics of the above information data in the form of charts.

2. Intelligent Analysis

Conducting data analysis and modeling in the chemical park according to the monitoring points, types of regulatory environmental protection data, monitoring time and other dimensions. And then it can comprehensively display the real-time data, monitoring standards, and video data in the form of statements, and analyze and display the actual data and index data of waste gas, waste residue and wastewater in the chemical park. Horizontal and vertical comparisons of the same series of data are supported to meet the analysis requirements of early warning and intelligent management.

3. Alarm Management

Set the maximum threshold for waste gas, waste slag, and wastewater, and display the alarm device, alarm time, and alarm type in a list in real time. When the monitoring data is higher than the maximum threshold, an alarm signal can be issued to remind the management to deal with it in time.

4. History Tracking

It supports to query data such as historical statistics records and historical mean values, and collect the maximum value, minimum value, and time label of variables in the query period. What’s more, system can view the out-of-limit running time of variables and their values, and perform summary statistics and export. Therefore, these data support for managers to make scientific decisions.

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.
