Solution for online water quality monitoring system

1、 Project background

In order to improve the water environment, standardize prevention and control goals at the macro level, and solve problems such as enterprise wastewater, drinking water quality, and groundwater pollution from the root, it is necessary to establish a comprehensive monitoring and management system for water quality, and improve the automation of water management.

The solution for online remote monitoring of water quality utilizes modern information technology to connect water quality data collectors distributed in different locations through a network, achieving real-time collection, transmission, storage, analysis, and display of water quality parameters, as well as timely alarm and handling of abnormal situations. This not only improves the efficiency and accuracy of water quality monitoring, reduces labor and material costs, but also enables timely detection and resolution of water quality issues, ensuring water environment safety.

2、 The current problems in water quality monitoring

1. A large amount of human and material resources are wasted. China has a vast territory, and the actual situation in each region is complex, and the actual situation of water resources is also different. Relying solely on existing standards for testing and judging the quality of water quality, the goals of water quality monitoring projects are unclear, and repeated monitoring of certain projects with low pollution levels consumes a lot of energy, resulting in a significant waste of human and material resources.

2. Lack of scientificity in water quality and environmental monitoring In China, the methods used in water quality and environmental monitoring are not scientific, and the proficiency and standardization of operators are not sufficient, which can lead to measurement results deviating. The water quality and environmental monitoring equipment is outdated, especially in some monitoring stations below the county level. The equipment is outdated, and the implementation conditions for actual water quality and environmental monitoring work are very poor. Moreover, the entire testing work is difficult to advance. There are problems with outdated monitoring methods and inadequate infrastructure.

3、 System architecture

In order to realize remote online monitoring of water quality data, we need a reliable, stable and high-performance data transmission terminal, that is, edge computing gateway. Edge computing gateway is a professional industrial equipment, which can convert various types of data interfaces RS232/485 into standard network protocol Modbus TCP and send data to the cloud or central server through wired or wireless methods (such as network cable/4G/5G, Wi Fi, etc.).

Data collection layer: The gateway mainly collects data by connecting sensors, collectors, and other devices;

Communication network layer: responsible for data transmission, network communication methods can be optionally equipped with network cables/2G/4G/WIFI, etc;

Platform application layer: refers to the Internet of Things cloud platform, responsible for presenting data, managing, and controlling systems, which can be managed on multiple terminals such as Android mobile apps, computer software, and computer web pages

4、 Implement functions

1. Real time collection: Temperature, turbidity, pH value, conductivity, dissolved oxygen, total phosphorus, total nitrogen, water level, flow rate and other data are monitored online, and can be automatically uploaded to the cloud platform. After processing, they are presented in real-time in the form of data reports or graphs, and displayed in the form of charts, allowing for a clear view of the changes in real-time data.

2. Intelligent management: supports manual, automatic, and remote control of the online water quality monitoring system, with flexible switching between the three methods and linked control of water pumps and other equipment;

3. Automatic alarm: trigger an alarm mechanism for events such as parameters, equipment failures, and equipment status that exceed the set limit values, and provide alerts through SMS, phone, WeChat, and other means;

4. Historical data: The data is automatically stored and saved for a long time. It can be queried, analyzed, and exported for a certain period of time anytime and anywhere on the cloud platform, and the historical data is intelligently analyzed to form data reports by day, month, and year;

5. Video surveillance: supports access to network cameras such as Hikvision and Firestone Cloud, and displays surveillance videos and collected data on the same screen;

6. Account management: supports multiple account and device logins, and divides accounts into management, operation, editing, read-only and other groups;

5、 Advantages of the plan

The online water quality monitoring system is an online monitoring system for scenarios such as water sources, rivers, and reservoirs. It integrates technologies such as the Internet of Things, big data, and remote control to achieve monitoring automation, intelligent early warning, and digital management. Historical data is queried and shared online, providing scientific basis for decision-making.

1. Easy to use: No need for network architecture, ready to install and use, fast to get started; Edge computing gateway not only has strong data processing capability, but also has security functions such as firewall, encryption, authentication, etc., to ensure the security and reliability of data transmission.

2. Free software: Free Android app software; Free web monitoring platform, free PC monitoring software, supporting hardware and software function development, providing customized system functions for special application scenarios

3. Communication distance: unlimited distance, remote monitoring is available both domestically and internationally; No matter where you are, as long as your phone has internet access, you can view real-time data.

4. Real time data: The data monitoring interface refreshes every 1 second; View historical data curves on mobile phones/computers at any time; Can export device monitoring data at any time;

5. Remote alarm: supports setting the upper and lower limits of sensor data for remote alarm; App push+alarm methods such as WeChat, phone, alarm, SMS, etc

6. Permission management: supports multiple groups of members to monitor the same device; Support the monitoring of multiple devices by the same member; Support member permission management.

7. Video surveillance: Supports access to Hikvision/Firestone Cloud cameras for synchronized viewing with data, making it more convenient.
