[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings.

[0023] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the descriptions of "preferred", "sub-preferred", etc. in the present invention are only used for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one such feature.

[0024] like Figure 1 As shown, a water quality detection method applied to a water quality management system includes a water quality detection device 1, a central processor 11 is provided on the water quality detection device 1, the central processor 11 is connected to a Bluetooth communication component 12 connected to a user smart device 2 for wireless communication, a display component 13 for displaying water quality detection information, a TDS electrode component 14, an ultraviolet transceiver component 15, a temperature sensor 16 and a button component 17, the button component 17 is provided with a power button, a calibration button and a detection button, the user smart device 2 stores the scoring criteria for relevant water quality data of different water types, and the detection steps are as follows:

[0025] S1. Press the power button to start the CPU, which initializes the TDS electrode assembly 14, the UV transceiver assembly 15, the temperature sensor 16, and enables the Bluetooth communication assembly 12 to wirelessly connect with the user's smart device 2;

[0026] S2, select the water type of the water to be tested through the user smart device 2, so that the user smart device 2 sends the corresponding scoring standard of the relevant water quality data to the central processor 11, place the water quality detection device 1 in the water to be tested, and press the detection button, the central processor controls the TDS electrode assembly 14, the ultraviolet transceiver assembly 15, and the temperature sensor 16 to work and collect water quality parameters, and send them to the central processor;

[0027] S3, the central processor calculates the relevant water quality data according to the collected water quality parameters, and calculates the score and water quality grade of the detected water quality according to the scoring standard, displays the detected water quality score through the display component 13 and displays the corresponding detected water quality grade through different colors, and sends it to the user's smart device 2 through the Bluetooth communication component 12, so as to achieve the function of quickly and accurately detecting the tap water quality data, greatly improve the accuracy of water quality detection, and display the water quality score and display different colors to indicate the water quality grade, so that the user can know the tap water quality more directly, and can synchronously upload the detected relevant water quality data to the user's smart device 2 for storage and analysis, so as to facilitate the user to review it. Among them, the relevant water quality data includes TDS total dissolved solids data, TOC total organic carbon data, COD chemical oxygen demand data, UV ultraviolet transmittance data, EC conductivity data and temperature data; the user's smart device 2 is a mobile phone, tablet computer, etc.

[0028] In this case, the Bluetooth communication component 12 and the user's smart device 2 are connected via BLE communication, so that the transmitted data is encoded and protected to ensure the security and integrity of data transmission.

[0029] In this case, after pressing the power button to start the central processor in S1, the central processor 11 controls the display component 13 to display a prompt to wait for Bluetooth connection. The user needs to trigger the user smart device 2 to enable the Bluetooth communication component 12 to wirelessly connect with the user smart device 2, and enter the water quality detection mode after the central processor 11 detects that the Bluetooth communication component 12 is connected to the user smart device 2 to perform water quality detection. Otherwise, the water quality detection equipment 1 cannot work normally, thereby ensuring that the relevant water quality data detected by the water quality detection equipment 1 is uploaded to the user smart device 2 to avoid data loss affecting the analysis.

[0030] In this case, the scoring standards include tap water scoring standards based on tap water quality data and filtered water scoring standards based on filtered water quality data filtered by ultrafiltration membrane or nanofiltration membrane. When testing water quality, the type of water to be tested can be selected through the user's smart device 2, so that the central processor obtains the scoring standards for the corresponding water type from the user's smart device 2 through the Bluetooth communication component 12, so that the water quality testing device 1 is suitable for detecting various types of water bodies. In this case, more water type scoring standards can be set to expand the water type detection range. Among them, the filtered water scoring standard is specifically a mineral water scoring standard, including TOC total organic carbon less than 1mg / L, COD chemical oxygen demand less than 2mg / L, and TDS total dissolved solids between 30-350mg / L. When testing filtered water, if the relevant water quality data are all within the filtered water scoring standard values, a green prompt is displayed for high-quality drinking water. If one of the items is not within the filtered water scoring standard values, a red prompt is displayed for unhealthy drinking water.

[0031] In this case, the CPU 11 will perform a calibration self-check after being started. The calibration self-check steps include:

[0032] S11, the central processor 11 is preset with a calibration time value; after the central processor 11 is started, it calculates the sleep time length, and when the sleep time length is greater than the calibration time value, the central processor 11 controls the display component 13 to display a calibration prompt, otherwise jumps to S2;

[0033] S12. During calibration, place the water quality testing device 1 in pure water and press the calibration button. The TDS electrode assembly 14, the ultraviolet transceiver assembly 15 and the temperature sensor 16 respectively detect corresponding electrical signals and send them to the central processor 11 for storage as the zero point calibration value of each water quality parameter. That is, after the water quality testing device 1 detects pure water, the electrical signal detected by the TDS electrode assembly 14 is used as the zero point for the TDS electrode assembly 14 to detect other types of water, the electrical signal detected by the ultraviolet transceiver assembly 15 is used as the zero point for the ultraviolet transceiver assembly 15 to detect other types of water, and the electrical signal detected by the temperature sensor 16 is used as the zero point for the temperature sensor 16 to detect other types of water. After calibration, jump to S2.

[0034] The calibration self-check greatly improves the detection accuracy of relevant water quality data, and prevents the problem of detection error when the water quality detection device 1 is not used for a long time.

[0035] In this case, the temperature data detection principle of the water quality detection equipment 1 is that a temperature comparison table corresponding to the water temperature digital signal generated by the temperature sensor 16 is preset in the central processing unit 11; in S2, the temperature sensor 16 is in contact with the water to be tested, and generates different analog voltage outputs according to the water temperature to be tested, and is converted into a water temperature digital signal after the A / D analog-to-digital conversion of the temperature sensor 16 and sent to the central processing unit 11; in S3, the central processing unit 11 obtains the temperature data by looking up the table according to the water temperature digital signal and the temperature comparison table.

[0036] In this case, the detection principle of EC conductivity data and TDS total dissolved solids data of the water quality detection equipment 1 is that the temperature compensation algorithm relationship between TDS total dissolved solids, EC conductivity and temperature is preset in the central processor 11; in S2, the TDS electrode assembly 14 contacts the water to be tested, and generates different currents according to the distribution of ions in the water, and the corresponding voltage signal is converted by the conversion circuit of the TDS electrode assembly 14. After the A / D analog-to-digital conversion of the TDS electrode assembly 14, the EC conductivity data of the water to be tested is obtained and sent to the central processor 11; in S3, the central processor 11 calculates the TDS total dissolved solids data according to the temperature data, EC conductivity data, temperature compensation algorithm relationship and the calibration value of the corresponding water quality parameter. Among them, the temperature compensation algorithm relationship is the relationship between temperature, conductivity and total dissolved solids obtained by curve fitting after multi-point sampling.

[0037] In this case, the detection principle of the UV ultraviolet transmittance data, TOC total organic carbon data and COD chemical oxygen demand data of the water quality detection equipment 1 is that the central processing unit 11 is preset with a relationship between UV ultraviolet transmittance and TOC total organic carbon and COD chemical oxygen demand; in S2, the ultraviolet transceiver component 15 contacts the water to be tested and controls the transmitting end of the ultraviolet transceiver component 15 to emit 275nm ultraviolet light, and after the receiving end of the ultraviolet transceiver component 15 receives the ultraviolet light, the conversion circuit of the ultraviolet transceiver component 15 converts the light intensity into a corresponding voltage signal, and after the A / D analog-to-digital conversion of the ultraviolet transceiver component 15, the UV transmittance data of the water to be tested is obtained and sent to the central processing unit 11; in S3, the central processing unit 11 calculates the TOC total organic carbon data and COD chemical oxygen demand data according to the relationship between UV ultraviolet transmittance and TOC total organic carbon and COD chemical oxygen demand and the calibration values ​​of the corresponding water quality parameters. The relationship is obtained by curve fitting after multi-point sampling and the relationship between UV transmittance and TOC total organic carbon and COD chemical oxygen demand.
