Description

An online water quality turbidity and color detection system Technical Field

[0001] This invention belongs to the field of water quality testing technology, and in particular relates to an online water turbidity and color detection system. Background Technology

[0002] Turbidity and color are important indicators for assessing the cleanliness and transparency of water bodies. With rapid industrialization and urbanization, water pollution is becoming increasingly serious, making real-time monitoring of turbidity and color increasingly urgent. Traditional methods for detecting turbidity and color are mostly offline, primarily single-parameter measurements, resulting in long detection cycles, poor data real-time performance, high costs, and susceptibility to human error. Data transmission is often limited to 4-20mA, leading to discrepancies between transmitted and measured values, mainly due to the distance of the communication line.

[0026] The present invention will be further described in detail below with reference to the embodiments given in the accompanying drawings.

[0027] Turbidity and color are important indicators for assessing the cleanliness and transparency of water bodies. With rapid industrialization and urbanization, water pollution has become increasingly serious, making the need for real-time monitoring of water turbidity and color increasingly urgent.

[0028] Currently, traditional methods for detecting water turbidity and color are mostly offline and involve single-parameter measurements. These methods suffer from problems such as long detection cycles, poor data real-time performance, high costs, and human error. Data transmission is mostly 4-20mA, and there are discrepancies between the transmitted values ​​and the actual measured values, mainly due to the distance of the communication line.

[0029] To address the aforementioned issues, this application proposes an online water quality turbidity and color two-parameter detection system. This system combines modern optical, electronic, and communication technologies, enabling real-time and continuous detection of water turbidity and color, and providing accurate and reliable data and data transmission, thus offering strong support for water quality monitoring and management.

[0030] As shown in Figure 1, an online water quality turbidity and color detection system includes a sampling module, a turbidity detection module, a color detection module, a data processing and analysis module, a communication module, and a power supply module.

[0031] The sampling module is used to automatically collect water samples;

[0032] The turbidity detection module is used to detect the turbidity of the water sample;

[0033] The colorimetric detection module is used to detect the colorimetric properties of the water sample;

[0034] The data processing and analysis module is used to receive water sample turbidity data and color data transmitted by the turbidity detection module and the color detection module, process, analyze and store the data in real time, and calculate the turbidity value and color value of the water sample.

[0035] The communication module includes an R485 communication interface for remote communication with the user, transmitting the data information analyzed by the data processing and analysis module to the user, enabling the user to remotely monitor the water sample in real time and understand the water quality status.

[0036] The power module is used to provide a stable power supply to the detection system.

[0037] It should be noted that the colorimetric detection module of this application detects the colorimetric properties of water samples using a scattering method. When light passes through a water sample containing suspended particles, the particles scatter the light. The system measures the intensity of the scattered light and, in conjunction with a known calibration curve, calculates the turbidity value of the water sample. The detection results are accurate and reliable.

[0038] The turbidity detection module in this application detects the turbidity of water samples using a colorimetric method. The colorimetric value of the water sample is determined by comparing its color with a standard color chart. In addition, the system can also employ an optical sensor to measure the absorbance of the water sample at a specific wavelength, thereby calculating the colorimetric value. The detection results are accurate and reliable.

[0039] The detection system of this application integrates two common flow path systems and detection units for turbidity detection and colorimetry detection. Turbidity and colorimetry are detected by scattering method and colorimetry respectively, and the detection results are accurate and reliable. A communication module is used to realize remote data transmission and remote monitoring, so that users can understand the water quality status at any time.

The colorimetric photocells 16 are connected to a data processing module to transmit the measured colorimetric data to the data processing module for analysis and calculation to obtain the colorimetric data value of the water sample.

[0044] In one embodiment, as shown in Figure 2, the turbidity detection module includes a turbidity detection tank 4 connected to a turbidity supply solenoid valve 9. A turbidity sensor 15 is provided on the top of the turbidity detection tank 4. The turbidity sensor 15 is connected to a data processing module to transmit the measured turbidity data to the data processing module for processing to obtain the turbidity data value of the water sample.

[0045] In one embodiment, as shown in Figure 2, the top of the colorimetric detection water tank 3 is provided with a colorimetric cleaning and colorimetric calibration port 17, and the bottom is connected to a colorimetric drain pipe. A colorimetric drain solenoid valve 8 is connected to the colorimetric drain pipe. A colorimetric water outlet pipe is connected to the upper end of one side of the colorimetric detection water tank 3. A colorimetric water outlet solenoid valve 7 is connected to the colorimetric water outlet pipe. The colorimetric drain solenoid valve 8 and the colorimetric water outlet solenoid valve 7 are respectively connected to the control module.

[0046] In one embodiment, as shown in Figure 2, the bottom of the turbidity detection tank 4 is connected to a turbidity discharge pipe, and a turbidity discharge solenoid valve 11 is connected to the turbidity discharge pipe. The upper end of one side of the turbidity detection tank 4 is connected to a turbidity outlet pipe, and a turbidity outlet solenoid valve 10 is connected to the turbidity outlet pipe. The turbidity discharge solenoid valve 11 and the turbidity outlet solenoid valve 10 are respectively connected to the control module.

[0047] In one embodiment, as shown in Figure 2, both the chromaticity sewage pipe and the turbidity sewage pipe are connected to a sewage pipe, and a miniature sewage pump 12 is connected to the sewage pipe.

[0048] In this example, the colorimetric measurement method involves adjusting the inlet flow meter 1; the control module issues a command to open the colorimetric water supply solenoid valve 6; when the colorimetric detection module 3 receives water to a high level, the colorimetric water outlet solenoid valve 7 is opened, and the micro sewage pump 12 is simultaneously opened (the micro sewage pump 12 is normally open); the colorimetric water supply solenoid valve 6 and the colorimetric water outlet solenoid valve 7 are closed, and after one minute, the colorimetric photocell 16 measures the data and transmits it to the data processing module 5. Based on the existing calibration K and B values, the module calculates the results, displays the results on the screen, and transmits them wirelessly to the monitoring platform via DTU, enabling unified data management and real-time monitoring of the operating status on the monitoring platform.

[0049] In this example, the turbidity measurement method involves adjusting the inlet flow meter 1; the control system issues a command to open the turbidity supply solenoid valve 9; when the turbidity detection module 4 reaches a high liquid level, the turbidity outlet solenoid valve 10 is opened, and the micro sewage pump 12 is simultaneously opened (the micro sewage pump 12 is normally open); the turbidity supply solenoid valve 9 and the turbidity outlet solenoid valve 10 are closed, and after one minute, the turbidity sensor 15 measures the water sample data and transmits the measured water sample data to the data processing module 5, calculates the results, displays them on the screen, and transmits them wirelessly to the monitoring platform via DTU, achieving unified data management and real-time monitoring of the operating status on the monitoring platform.
