Water quality detection system

Abstract

The invention provides a water quality detection system, comprising a water quality sensor, a wireless sensor network and a receiving terminal, wherein the water quality sensor comprises a housing; the housing is internally provided with an optical system; the optical system is connected with a photoelectric conversion unit; the photoelectric conversion unit is used for sending signal data to a data processing unit, and the data processing unit sends out the data by means of a communication unit; the water quality sensor also comprises a lithium battery; the lithium battery is connected with the communication unit by a cable. The water quality detection system adopts a Raman scattering technique and utilizes a photoelectric conversion and analysis unit installed at the tail end of the sensor to automatically analyze the content of particulate matters of water quality, and the detection data is sent to the receiving terminal in a wired or wireless way; the system can be placed in a measurement area in a spreading way; a wireless sensor network can be used for data collection; the system is self-equipped with the battery; the system is convenient in recovery, simple to install, small in whole machine volume, high in intellectualization level and good in safety, and not only meets the requirements of a distributed water quality PPM measurement function, but also realizes online water quality detection.

Description

Technical field [0001] The invention belongs to the field of sensing technology, and particularly relates to a water quality detection system. Background technique [0002] Automatic water quality monitoring started early in foreign countries, and my country is still at the exploratory stage in the construction of early warning and forecasting systems such as automatic water quality monitoring and rapid mobile analysis. Since 1998, my country has successively built 100 national surface water quality automatic monitoring stations in 10 key river basins of the seven major water systems. According to the needs of environmental management, various localities have also established more than 400 local-level automatic surface water quality monitoring stations. , A weekly report of automatic water quality monitoring is realized. At present, most of the automatic monitoring systems used in China are imported equipment from abroad. The manufacture of automatic water quality monitoring devi...

AI Technical Summary

Problems solved by technology

At present, most of the automatic monitoring systems used in China are imported equipment from abroad, and the manufacturing of automatic water quality monitoring devices can no longer meet the needs of rapid development of water quality monitoring. Therefore, domestic automatic monitoring instruments have broad development prospects and potential sales markets.
