Split type full-spectrum online water quality monitoring device

Abstract

The invention provides a split type full-spectrum online water quality monitoring device. A sensing probe and a monitoring host are separately and independently arranged, and the sensing probe can bein communication connection with the monitoring host in a photoelectric signal transmission mode. The technical scheme of the invention is as follows: the split type full-spectrum online water qualitymonitoring device is composed of a monitoring host and a plurality of sensing probes. The sensing probe and the monitoring host are in communication connection in a photoelectric mode, and the sensing probe is used for being immersed in a to-be-monitored water quality sample environment to periodically and continuously monitor parameter changes of water quality factors and transmitting the parameter changes to the monitoring host in real time so as to process and transmit the parameter changes to a remote server.

Description

【Technical field】 [0001] The invention mainly relates to a full-spectrum water quality on-line monitoring device for detecting changes in water quality, especially a split-type full-spectrum water quality on-line monitoring device that is easy to carry and use. 【Background technique】 [0002] Water pollution monitoring is one of the important tasks of environmental management. The traditional water quality monitoring is basically a single factor monitoring through the color chemical reaction method, and the price of a single monitoring system is high and there are problems such as secondary pollution of waste liquid. [0003] At the same time, although the existing full-spectrum water quality monitoring equipment has been used in the monitoring of surface water such as rivers and lakes in the prior art, it has the following deficiencies: (1) the spectral analysis of the existing full-spectrum water quality monitoring and analysis equipment The unit is integrated in the sens...

The traditional water quality monitoring is basically a single factor monitoring through the color chemical reaction method, and the price of a single monitoring system is relatively high and there are problems such as secondary pollution of waste liquid

[0003] At the same time, although the existing full-spectrum water quality monitoring equipment has been used in the monitoring of surface water such as rivers and lakes in the prior art, it has the following deficiencies: (1) the spectral analysis of the existing full-spectrum water quality monitoring and analysis equipment The unit is integrated in the sensor probe, the spectral line bandwidth is narrow, and the spectral analysis ability is low and cannot be adjusted, resulting in equipment hardware problems such as less monitoring content and low precision; (2) The sensor probe of the existing monitoring and analysis equipment adopts single light The analysis method of long-range transmission spectrum absorption, the spectral absorption light path is small, resulting in low analysis accuracy of the monitoring and analysis equipment; (3) When using the existing monitoring and analysis equipment for data analysis of the spectrum, it cannot effectively solve the background interference, particle scattering, spectrum, etc. Problems such as absorption of cross-interference; (4) The existing monitoring and analysis equipment does not have the function of on-site zeroing and calibration, which cannot solve the problem of monitoring drift caused by equipment aging and interference during use; In the probe, the equipment can only detect one type of water quality factor at the same time, and lacks the ability to monitor and analyze multiple types of water quality factors
