Solution for online monitoring system for sewage treatment

1、 Industry status quo

The construction of urban sewage treatment facilities has been highlighted as a prominent position in urban infrastructure construction, bringing the construction of urban sewage treatment facilities into a new stage of development. However, at present, water quality monitoring of pollution sources and sewage discharge channels in various parts of the country is still in the manual monitoring stage, which is difficult to reflect the continuous changes in sewage discharge from enterprises and cities. In terms of water resource pollution, efforts are constantly being made to strengthen governance. However, due to factors such as weak environmental protection awareness and the drive of interests, arbitrary discharge of sewage and non-standard discharge often occur, resulting in serious environmental pollution. Therefore, providing an effective, practical, and advanced monitoring system and solution in monitoring and supervision, establishing an online monitoring system for sewage treatment, is extremely urgent. Improving water quality monitoring capabilities is imperative.

The traditional remote sewage online monitoring system is developed through secondary development of configuration software or customized development by enterprises at a huge cost. These two methods have high costs ranging from 30000 to 40000 to several hundred thousand, and the construction period is relatively long. At the same time, there are also development risks that cannot ensure 100% functionality. In the later maintenance process, it is often necessary to arrange professional programmers to maintain the system, which results in high operating costs. 2、 EMCP IoT Cloud Platform Solution

2.1 System composition

2.1.1 Online sewage detection instrument

At present, common manufacturers of online water quality analysis instruments include HACH in the United States, SERES in France, WTW in Germany, E+H in Germany, KUNTZE in Germany, Shimadzu in Japan, Horiba in Japan, SCAN in Austria, etc. The collected water quality parameters include temperature, pH, dissolved oxygen, conductivity, turbidity, chlorophyll, blue-green algae, chemical requirement, ammonia nitrogen, total phosphorus, total organic carbon, residual chlorine, fluoride, cyanide, etc.

2.1.2 Wireless transmission equipment

Hebei Blue Bee EG20 uses a standard 232/485 communication interface. As long as a GPRS data card is built in, it can communicate with the Internet. After the greenhouse field collection terminal is connected through 232/485, the EG20 module will automatically collect the measured values of each sensor and transmit the data to the EMCP Internet of Things cloud platform through GPRS network. EG20 has strong universality, as long as the on-site water quality online monitoring equipment supports MODBUS protocol, it is plug and play, compact in size, easy to install and use, and does not require too many professional skills.

2.1.3 EMCP Internet of Things Cloud Platform

Users can install the EG20 module introduced above on the serial port of the sewage detection equipment, log in to the EMCP IoT cloud platform through computer networking, add on-site devices, and configure data formats to complete device access. The EMCP IoT platform analyzes and processes real-time water quality parameters collected on site, not only producing corresponding statistical reports and trend analysis, but also displaying them to users in an intuitive chart and curve format.

Overall system architecture

Firstly, connect the water quality detection equipment to EG20 using the 485 bus, insert the SIM card into EG20, connect EG20 to the computer through a 232 data cable, and power on all devices. Open the DTU configuration software to check the mold progress

3、 System implementation

We will not elaborate on common matters such as power supply design, installation, and SIM card. During installation and use, safety must be taken into consideration, and it is best to install it through professional personnel. If there are any problems during the installation process, Blue Bee technical support personnel are very willing to work with everyone to solve the problem.

Step 1: Purchase our EG20 smart wireless gateway. Log in to the official website to contact our sales personnel.

Step 2: Users can choose reliable online air pollution detection equipment on the market and connect the detection equipment to the 485 communication port of the EG20 module through the 485 bus.

Step 3: Configure DTU and check module status. Please refer to the DTU Configuration Manual here. We can download it from the official website download center.

Step 4: Open the EMCP IoT Cloud Platform www.lfemcp.com to register an account. After successful registration, enter the platform to add devices and configure data rules. Please refer to the EMCP Cloud Platform User Manual, which can be downloaded from the official website download center. If you need to access the video, please contact our customer service for authorization.

Step 5: After completing the above steps, we can view the air environment data of the device installation location on the web page and mobile app.

4、 Summary

The application of online remote detection of air pollution is becoming increasingly widespread. The traditional implementation requires developers to program, and with the help of the EMCP IoT cloud platform, you can avoid programming and solve the difficulties of remote water quality detection quickly, conveniently, cheaply, and multifunctional. The application of the EMCP IoT cloud platform in remote online sewage detection has been fully utilized. It is believed that the application of the EMCP IoT cloud platform will also be more applied in other fields, and the value of its open IoT is constantly being reflected.

The entire process does not require programming, just simple configuration, allowing the device to connect to the cloud in minutes. For more functions, please follow the official website of Hebei Lanfeng Technology at www.lanfengkeji.com
