Water quality online monitoring system and method based on Internet of things

Abstract

The invention discloses a water quality online monitoring system and method based on the Internet of Things, which is characterized in that it includes a sensing node, a water quality data cloud platform of the Internet of Things, a background server, and a mobile monitoring terminal; the sensing node is used for on-site data Acquisition, acquisition and real-time display of water quality pollution parameters at monitoring points, and automatically judges whether sound and light alarms are required; the background server collects water quality sensor data of sensing nodes through the AD analog-to-digital conversion circuit integrated in the chip, and uses I / O Port to collect temperature sensor data, use SPI serial peripheral interface to communicate with SD card, drive the wireless data terminal of 3G communication module through USART serial port, use ordinary I / O port to simulate communication sequence to drive LCD screen and connect keyboard, which is convenient for system development Debugging; the mobile monitoring terminal is connected to the Internet of Things water quality data cloud platform through the Internet to remotely monitor the water quality. The invention has the advantages of simple structure, low use and maintenance cost, and superior performance compared with the same type of products.

Description

technical field [0001] The invention relates to the technical field of water quality monitoring, and more specifically relates to an online water quality monitoring system and method based on the Internet of Things. Background technique [0002] Water resources are one of the most important resources necessary for our human life. They are the necessary living conditions for our human beings to survive and reproduce. Our country is focusing on the road of sustainable economic development, and the sustainable use of water resources is an important method. one. In recent years, groundwater in many cities across the country has been polluted to a great extent in point and surface forms, and the situation of massive pollution of such water bodies has a tendency to worsen day by day. The increasingly serious water pollution will not only affect the lives of the common people, but also have a huge impact on enterprises and industries. Water pollution not only greatly reduces the ...

AI Technical Summary

Problems solved by technology

Water pollution not only greatly reduces the use of water bodies, but also further aggravates the severity of water shortages, which has brought great adverse effects on the sustainable development strategy that my country is vigorously implementing in recent years, and the safety of drinking water for the people There is a huge threat, and the safety of the people's lives cannot be guaranteed.

In recent years, the pollution of water resources has become increasingly serious. Water resources monitoring is the most basic work in the response and prevention of water pollution. Due to the rapid increase in demand for water resources, a large amount of untreated industrial wastewater and domestic wastewater are directly discharged into rivers, making water bodies The situation is seriously polluted, and the detection and protection of water resources have attracted more and more attention from the masses and the public. However, the current water quality information release system on the market has problems such as untimely data updates and inadequate monitoring.
