[0035] First embodiment

[0036] As Figure 1 shown, the intelligent Internet of Things turbidity meter provided by the embodiment includes a water pipeline 100, a light source system 200, a detector 300 and an AIoT module 400. The light source system 200 is arranged on the water pipeline 100, and the light source system 200 is used to irradiate the liquid in the water pipeline 100. The detector 300 is arranged on the water pipeline 100, and the detector 300 is used to receive and process the light signal emitted by the light source system 200 to convert the light signal into an electric signal. The AIoT module 400 is electrically connected with the detector 300, and the AIoT module 400 is used to judge the turbidity of the liquid according to the electric signal emitted by the detector 300.

[0037] In detail, the light source system 200 and the detector 300 are arranged on the water pipeline in an inlaid manner. The emitting port of the light source system 200 is located on the pipeline wall inside the water pipeline 100, so as to facilitate the light emitted by the light source system 200 to irradiate the liquid in the water pipeline 100. The detection end of the detector 300 is also located on the pipeline wall inside the water pipeline 100, and the AIoT module 400 is also on the water pipeline 100.

[0038] It can be understood that when the light source passes through the liquid (water) in the water pipeline 100, part of the light is scattered, part of the scattered light is captured by the detector 300, the detector 300 detects the intensity of the captured light, and then sends a specific signal to the AIoT module 400. After the signal is processed by the AIoT module 400, it can be used to determine the turbidity of the liquid in the water pipeline 100 and whether it meets the standard. Compared with the prior art, the embodiment has a simple structure, which can solve the problem of complex turbidity detector detection, improve the efficiency of turbidity detection, and save manpower.

[0039] Specifically, as shown in Figure 2 The irradiation direction of the light source system 200 and the receiving direction of the detector 300 are between 0-360°. In this embodiment, the irradiation direction of the light source system 200 and the receiving direction of the detector 300 are 90 degrees. Because in the 90-degree direction, the proportion of light directly scattered by suspended particles is large, and the proportion of reflected light entering the 90-degree direction after multiple reflections on the surface of the container is small, the signal-to-noise ratio is highest when receiving light intensity signal, so 90 degrees is selected as the angle of the light source system 200 and the detector 300. In other embodiments, different angles can be selected according to actual conditions.

[0040] Further, the inner wall of the water pipeline 100 is provided with a black light-absorbing layer 110. The purpose of the black light-absorbing layer 110 is to absorb the light reaching the inner wall of the water pipeline 100, so that the light is reflected, thereby improving the accuracy of the detector 300 measurement.

[0041] In addition, the inner wall of the black light-absorbing layer 110 is provided with a light-trapping structure 120. In detail, in this embodiment, the light-trapping structure 120 is provided with two, the light-trapping structure 120 is rectangular, and the two light-trapping structures 120 are uniformly arranged on the cross section of the water pipeline 100 with the light source system 200 and the detector 300, that is, they are spaced apart by 90°. It can be understood that the light-trapping structure 120 can repeatedly and fully absorb light when the light enters the light-trapping structure 120, and the effect is relatively good compared with the black light-absorbing layer 110.

[0042] Further, the inner wall of the black light-absorbing layer 110 is provided with a transparent layer 150. It can be understood that the water in the water pipeline 100 is generally used for daily use, so in order to ensure that the turbidity of the water is measured without being contaminated, the transparent layer 150 is arranged inside the water pipeline 100, which separates the black light-absorbing layer 110, the detector 300 and the light source system 200 from the water in the water pipeline 100, and does not affect the measurement effect.

[0043] Secondly, the water pipeline 100 is provided with a water outlet 130 and a water inlet 140, and the water inlet 140 and the water outlet 130 are connected with the water inlet pipe 600 and the water outlet pipe 500 respectively. In detail, the water inlet pipe 600 and the water outlet pipe 500 are made of stainless steel pipe or PE pipe, and in other embodiments, in order to ensure the service life of the water inlet pipe 600 and the water outlet pipe 500 and save costs, the pipes made of cast iron material can also be used.

[0044] Further, the water inlet 140 and the water outlet 130 are arranged at the left end and the right end of the water pipeline 100 respectively, and the light source system 200 and the detector 300 are located between the water inlet 140 and the water outlet 130. It can be understood that the arrangement of the light source system 200 and the detector 300 is determined according to the best position for measurement.

[0045] In this embodiment, the water inlet 140 and the water inlet pipe 600 are connected together by welding or bonding process, and at the same time, the water outlet 130 and the water outlet pipe 500 are also connected together by welding or bonding process. In addition, in other embodiments, the water outlet 130 and the water inlet pipe 600, and the water inlet 140 and the water outlet pipe 500 can be connected by setting a threaded pair, which is convenient for disassembly and installation.

[0046] In addition, the intelligent Internet of Things turbidity meter provided in this embodiment further comprises a mobile display end (not shown in the figure), which is wirelessly connected with the AIoT module 400, and is used for receiving and displaying the turbidity of the liquid judged by the AIoT module 400. In detail, the terminal display compares with the turbidity standard diagram, and finally determines whether the measured water turbidity meets the standard, and at the same time, the turbidity of the water is displayed and monitored in real time, and an alarm is given when it exceeds the normal range.

[0047] Second embodiment

[0048] The intelligent Internet of Things turbidity meter provided in this embodiment is substantially the same as the intelligent Internet of Things turbidity meter of the first embodiment, and the difference between the two is that the light trapping structure 120 in the intelligent Internet of Things turbidity meter of this embodiment is provided with six.

[0049] As Figure 3 shown, in the intelligent Internet of Things turbidity meter provided in this embodiment, four light trapping structures 120 are added in this embodiment relative to the first embodiment, and the four newly added light trapping structures 120 can be randomly arranged in any direction. It can be understood that the arrangement of six light trapping structures 120 can absorb more light, and the absorption effect is better than that of two light trapping structures 120, thereby improving the detection accuracy.

[0050] Third embodiment

[0051] The embodiment provides a smart Internet of Things turbidimeter, which is basically the same as the smart Internet of Things turbidimeter of the second embodiment, and the difference between the two is that the light trapping structure 120 in the smart Internet of Things turbidimeter of the embodiment is provided with ten.

[0052] As Figure 4 shown, in the smart Internet of Things turbidimeter provided by the embodiment, four light trapping structures 120 are added in the embodiment relative to the second embodiment, and the four newly added light trapping structures 120 can be randomly arranged in any direction. Similarly, it can be obtained that the ten light trapping structures 120 can absorb more light, and the absorption effect is better than that of the six light trapping structures 120, thereby improving the detection precision.

[0053] The embodiment also provides a working principle of a smart Internet of Things turbidimeter, which is as follows:

[0054] In order to solve the problem of complicated detection of the turbidimeter, the application provides a structure design of a smart Internet of Things turbidimeter. In the structure, the light source and the detector 300 are placed at 90 degrees on the side of the water flow channel with the transparent layer 150, and are wrapped with a black light-absorbing layer 110 on the periphery. The principle adopted is as follows: the light source emits a parallel light which propagates in the sample liquid, if there is no any suspended particle in the liquid, the light beam will not change direction when it propagates in a straight line; if there is a suspended particle, the light beam will change direction when it encounters the particle. Thus, different direction scattering light is formed. The more the suspended particles (the higher the turbidity), the more serious the light scattering. Thus, the intensity of the scattering light increases. Among the scattering light in the 90-degree direction, the proportion of the light directly scattered by the suspended particles is relatively large, and the proportion of the reflected light entering the 90-degree direction after multiple reflections on the surface of the container is relatively small. Therefore, the signal-to-noise ratio is the highest when the light intensity signal is received, so 90 degrees is selected as the angle of the light source and the detector 300.

[0055] The scattering light measurement method of the turbidimeter is called scattering method. The scattering light intensity in the direction of 90 degrees with the incident light conforms to the Rayleigh formula:

[0056] Is = ((KNV2) / lambda) x I0

[0057] Wherein: I0 is the incident light intensity, Is is the scattering light intensity, N is the unit solution particle number, V is the particle volume, lambda is the incident light wavelength, and K is the coefficient. Under the condition that the incident light is constant, within a certain turbidity range, the scattering light intensity is proportional to the turbidity of the solution. The scattering light intensity (signal intensity) corresponding to the turbidity (concentration) of different solutions is obtained by testing the standard solution, and the calibration curve is fitted. In the actual measurement process, the sample concentration can be obtained according to the measured light intensity combined with the calibration curve. Then, after the receiver and the AIoT module are connected, the light intensity change can be detected in real time, so that the purpose of real-time online monitoring is achieved.

[0058] In summary, the intelligent Internet of Things turbidity meter provided by the embodiment has at least the following advantages:

[0059] When the light emitted by the light source system 200 passes through the liquid (water) in the water pipeline 100, part of the light is scattered. Part of the scattered light is captured by the detector 300. The detector 300 detects the intensity of the captured light and then sends a specific signal to the AIoT module 400. After the signal is processed by the AIoT module 400, it can be used to determine the turbidity of the liquid in the water pipeline 100 and whether it meets the standard. The structure provided by the embodiment is simple compared with the prior art. It can solve the problem of complex turbidity meter detection, improve the efficiency of turbidity detection, and save manpower.

[0060] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
