Problems solved by technology

The problem is that there are many indicators that need to be detected. During the detection process, multiple instruments are required to detect at the same time, and many detection processes are very complicated, requiring the use of various chemical reagents or test papers, as well as various complicated instruments.
In view of this situation, real-time monitoring of water quality requires a combination of multiple devices, and its cost is also quite expensive
The crux of the problem is that due to the use of indicators for monitoring, if some substances that are not included in the indicators are mixed in the water, although the water quality has changed, the water quality indicators do not indicate the mixing of these substances.

Embodiment 1

[0041] This embodiment is a device for monitoring water quality on-line, such as figure 1 shown. This embodiment includes: a spectral water quality monitor installed at each water quality monitoring point, each of the described spectral water quality monitors is connected to the central monitoring station through a public communication network; The spectral water quality sensor of absorption, the spectral water quality sensor is connected with the curve generator that correlates the absorption with the wavelength, and the curve generator is connected with the three-dimensional graph generator that correlates the curve with the time axis, and the three-dimensional The graphics generator is connected with the recorder, and the recorder is connected with the public communication network; the central monitoring station includes: a three-dimensional graphics analyzer connected with the public communication network, and the three-dimensional graphics analyzer is connected with the c...

Embodiment 2

[0058] This embodiment is an improvement of the first embodiment, and is based on the refinement of the public communication network. The public communication network described in this embodiment is: a wired communication network or a wireless communication network or a combination of both.

[0059] The communication network can be a local area network or a wide area network, and data transmission is carried out in the form of wireless or wired. That is, it can use WIFI to connect to a wired network to form a transmission, and can also connect to a wired network through a 3G, 4G wireless communication network to form a data transmission.

Embodiment 3

[0061] This embodiment is an improvement of the second embodiment, and is a refinement of the second embodiment regarding the spectral sensor. The measurement spectrum range of the spectral water quality sensor described in this embodiment is: 200-710nm.

[0062] The spectral sensor can be an independent sensor, which only includes a light source and a photosensitive chip, or a relatively complete system, which includes some corresponding processing chips in addition to a light source and a photosensitive chip. Because some chips have very powerful functions, even including the function of surfing the Internet, that is, they can be indirectly connected to the network. However, due to the particularity of this embodiment, the processing of curves and three-dimensional graphics is required, so the finished spectral sensor needs to be modified. Of course, sensors can also be specially designed to combine embedded system chips that can form curves and three-dimensional graphics w...

Abstract

The invention relates to a device and method for monitoring the water quality on line. The device comprises a spectral water quality monitoring instrument, wherein the spectral water quality monitoring instrument is connected with a central monitoring station through a public communication network and comprises a spectral water quality sensor, a curve generator, a three-dimensional graph generator ad a recorder; the central monitoring station comprises a three-dimensional graph parser, a central analyzer, a central database and a three-dimensional graph display device. According to the device and the method disclosed by the invention, a absorbing capacity-waveband curve is associated with time to form an absorbing capacity-waveband-time three-dimensional graph; the change of the graph is observed, and only the change amplitude of the current graph in comparison to a previous graph is monitored while specific data of water quality are not acquired anymore; in case of large change, specific analysis to the water quality data is carried out, and then key factors affecting the change are found out. According to the device and the method disclosed by the invention, the monitoring process is visualized, the monitoring process is greatly simplified, the equipment cost is lowered, and an effect of comprehensively monitoring the water quality by using least equipment resources is achieved.

Description

technical field [0001] The invention relates to a device and method for monitoring water quality on-line, which is a device and method for monitoring product quality of environmental protection or drinking water, and a device and method for real-time monitoring of water quality. Background technique [0002] Existing water quality monitoring facilities, such as the monitoring of flowing water, including rivers, lakes, and tap water, mainly rely on the detection of various indicators of the water, and then evaluate the quality of the water according to the changes in the indicators. This detection method is accurate and effective. The problem is that there are many indicators to be detected, and multiple instruments are required for simultaneous detection during the detection process, and many detection processes are very complicated, requiring the use of various chemical reagents or test papers, as well as various complicated instruments. In view of this situation, real-tim...
