[0054] Exemplary embodiments of the present disclosure will be described in greater detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it is to be understood that the present disclosure can be variously implemented without being limited to the embodiments set forth herein.

The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0055] In some embodiments of the present application, referring to Figure 1 The present embodiment provides a river discharge outlet monitoring and early warning method based on Internet of Things, comprising the following steps:

[0056] S100, draw a river and discharge outlet map, set water quality detection sensors and flow meters on discharge outlets along the river, and position each water quality detection sensor and discharge outlet, match the positioning information of the water quality detection sensor with the position of the discharge outlet;

[0057] S200, collect water quality data and positioning information of the water quality detection sensor in real time, transmit the water quality data and positioning information of the water quality detection sensor to a monitoring platform in real time through a wireless communication module, monitor whether the quality of sewage discharged from the discharge outlet meets the standard in real time, and determine whether to perform primary early warning on the discharge outlet;

[0058] S300, when the quality of sewage does not meet the standard, perform primary early warning on the discharge outlet according to the discharge amount of the sewage that does not meet the standard, collect the pollutant concentration of the sewage that does not meet the standard, determine whether to adjust the primary early warning level, and when it is determined to adjust, perform first-level adjustment on the primary early warning level according to the pollutant concentration of the sewage that does not meet the standard;

[0059] S400, collect the flow rate of the water body of the river, determine whether to perform second-level adjustment on the primary early warning level or the primary early warning level after the first-level adjustment according to the flow rate of the water body, and when it is determined to perform second-level adjustment, perform second-level adjustment on the primary early warning level or the primary early warning level after the first-level adjustment according to the size of the flow rate of the water body of the river;

[0060] S500, display the adjusted early warning level on the map.

[0061] It can be understood that by drawing a map of the river channel and the discharge port and accurately positioning the water quality detection sensor, real-time monitoring of each discharge port is ensured. The water quality detection sensor continuously collects water quality data and transmits it to the monitoring platform through the wireless communication module, ensuring that the manager can at any time master the sewage discharge situation of the discharge port and timely identify whether the sewage meets the standard. When it is found that the sewage does not meet the standard, a preliminary warning is issued according to the sewage discharge amount and the pollutant concentration, and the warning level is dynamically adjusted according to the concentration change. In addition, the introduction of the river water flow rate can further adjust the warning level according to the flow of the water body, making the warning mechanism more intelligent and flexible. Finally, all the adjusted warning information will be displayed in real time on the map, and the manager can see the status of each discharge port at a glance, so as to take corresponding measures in time, thereby effectively preventing pollution from spreading and protecting the health of the river ecological environment.

[0062] Specifically, the discharge port in the present application refers to the discharge port after sewage treatment; whether the sewage quality meets the standard refers to whether the sewage discharged after treatment meets the national discharge standard.

[0063] In some embodiments of the present application, a map of the river channel and the discharge port is drawn, the water quality detection sensor and the flowmeter are arranged on the discharge port along the river channel, and each water quality detection sensor and discharge port is positioned. When the positioning information of the water quality detection sensor is matched with the position of the discharge port, it comprises:

[0064] The geographical data of the river channel is collected by the geographic information system technology, including the shape, direction of the river channel and the discharge port, and the river channel and the discharge port map is established combined with remote sensing data, wherein each discharge port is identified according to its position;

[0065] The water quality detection sensor is arranged on each discharge port, and the global positioning system is used to position the water quality detection sensor, so that the position information of each water quality detection sensor is matched with the corresponding discharge port.

[0066] It can be understood that by collecting the geographical data of the river channel through the geographic information system and remote sensing technology, and accurately positioning the water quality detection sensor and the discharge port combined with the global positioning system, fine management of the river channel and the discharge port can be realized, ensuring that the position of the discharge port is accurately matched with the positioning information of the sensor, which helps to improve the coverage and accuracy of sewage monitoring, so that the manager can obtain the water quality data of each discharge port in time. At the same time, the combination of geographical data and remote sensing information can draw an accurate map of the river channel, providing a visual basis for subsequent sewage discharge monitoring and warning, greatly improving the efficiency and accuracy of water quality monitoring.

[0067] In some embodiments of the present application, the quality of the sewage discharged by the discharge port is monitored in real time to determine whether a preliminary warning is given to the discharge port, comprising:

[0068] When the sewage discharged from the discharge port is detected by the water quality detection sensor, if the detection result is not up to standard, it is determined to give a primary warning to the discharge port;

[0069] When the detection result is up to standard, it is determined not to give a primary warning to the discharge port.

[0070] In some embodiments of the present application, when the sewage quality is not up to standard, the primary warning to the discharge port is given according to the discharge amount of the non-standard sewage, including:

[0071] The discharge amount range is preset, if the discharge amount of the non-standard sewage is less than the minimum value of the discharge amount range, a first-level warning is given to the discharge port;

[0072] If the discharge amount of the non-standard sewage is greater than or equal to the minimum value of the discharge amount range, and the discharge amount of the non-standard sewage is less than or equal to the maximum value of the discharge amount range, a second-level warning is given to the discharge port;

[0073] If the discharge amount of the non-standard sewage is greater than the maximum value of the discharge amount range, a third-level warning is given to the discharge port;

[0074] Among them, the warning levels from weak to strong are first-level warning, second-level warning and third-level warning.

[0075] It can be understood that by monitoring the quality of sewage discharged from the discharge port in real time, it can be quickly judged whether a warning is needed, and the discharge amount of sewage is classified for warning, which effectively improves the sensitivity and accuracy of pollution monitoring. The threshold is set according to the discharge amount of sewage, and the warning intensity is gradually increased from the first level to the third level, so as to ensure that minor emission problems are handled in time, and serious pollution causes higher level alarm, prompting the manager to take prompt measures. This dynamically adjusted warning system can more reasonably reflect the pollution degree, prevent environmental deterioration, and improve monitoring and management efficiency.

[0076] In some embodiments of the present application, the pollutant concentration of non-standard sewage is collected, and whether to adjust the primary warning level is determined, including:

[0077] The pollutants include ammonia nitrogen, total nitrogen, chemical oxygen demand, etc.;

[0078] The maximum concentration of pollutants is set, including the maximum concentration of ammonia nitrogen, the maximum concentration of total nitrogen, and the maximum concentration of chemical oxygen demand;

[0079] If the concentration of each pollutant is less than the maximum concentration of pollutants, it is determined not to adjust the primary warning level;

[0080] If there is a pollutant concentration greater than the corresponding maximum concentration of pollutants, it is determined to adjust the primary warning level.

[0081] In some embodiments of the present application, if there is a pollutant concentration greater than its corresponding maximum pollutant concentration, the adjustment of the primary warning level is determined, including:

[0082] If there is a pollutant concentration greater than its corresponding maximum pollutant concentration, the primary warning level is determined to be increased by one level;

[0083] If there are two kinds of pollutant concentrations greater than their corresponding maximum pollutant concentrations, the primary warning level is determined to be increased by two levels;

[0084] If there are three kinds of pollutant concentrations greater than their corresponding maximum pollutant concentrations, the primary warning level is determined to be increased by three levels.

[0085] It can be understood that by real-time monitoring and grading judgment of the concentrations of pollutants such as ammonia nitrogen, total nitrogen and chemical oxygen demand in substandard sewage, more refined warning adjustment is realized. When the pollutant concentration exceeds the preset maximum value, the warning level is gradually increased according to the number of pollutants exceeding the standard, ensuring the accuracy and timeliness of the warning, which not only effectively distinguishes the pollution degree, but also comprehensively evaluates multiple pollutants, so as to quickly respond to different degrees of water quality deterioration, help managers take appropriate measures in time, avoid the expansion of environmental problems, and improve the efficiency of water quality management.

[0086] In some embodiments of the present application, the water flow rate of the river is collected, and when determining whether to make a secondary adjustment to the primary warning level or the primary warning level after a first adjustment, including:

[0087] A minimum water flow rate is preset, and if the water flow rate is less than the minimum water flow rate, it is determined that no secondary adjustment is made to the primary warning level or the primary warning level after the first adjustment;

[0088] If the water flow rate is greater than or equal to the minimum water flow rate, it is determined that a secondary adjustment is needed to the primary warning level or the primary warning level after the first adjustment.

[0089] In some embodiments of the present application, when it is determined that a secondary adjustment is needed, the primary warning level or the primary warning level after the first adjustment is adjusted according to the water flow rate of the river, including:

[0090] A maximum water flow rate is preset, and if the water flow rate is greater than or equal to the minimum water flow rate and the water flow rate is less than or equal to the minimum water flow rate, the primary warning level or the primary warning level after the first adjustment is increased by one level;

[0091] If the water flow rate is greater than the maximum water flow rate, the primary warning level or the primary warning level after the first adjustment is increased by two levels.

[0092] It can be understood that by collecting the flow rate of the river water body and adjusting the primary warning level or the warning level after the first adjustment according to the change of the flow rate, the accuracy of the warning system is improved. When the flow rate is fast, the pollutants may spread more quickly, and at this time, the warning level is raised to respond to the risk of pollution spread in time; when the flow rate is slow, the warning level does not need to be further adjusted, avoiding unnecessary warning escalation, fully considering the influence of the change of the river flow on the pollution spread, and being able to more effectively reflect the actual water quality condition, improving the efficiency and reliability of the river pollution monitoring.

[0093] In some embodiments of the present application, when the adjusted warning level is displayed on the map, it includes:

[0094] The final warning level of each discharge port is marked on the discharge port map of the river in different colors or symbols;

[0095] When the warning level changes, the warning level of the corresponding discharge port, the real-time water quality data of the water quality detection sensor, the pollutant concentration data, the sewage discharge amount data and the water flow rate and the like on the map are automatically updated.

[0096] It can be understood that by marking the final warning level of each discharge port on the map in different colors or symbols and automatically updating the map information when the warning level changes, intuitive and dynamic river pollution monitoring is realized. The manager can quickly identify high-risk discharge ports through the map and take timely measures. At the same time, the real-time display of water quality data, pollutant concentration, discharge amount and water flow rate and the like enhances the transparency and decision-making efficiency, which helps to more accurately analyze the pollution source and its influence on the river environment, and improves the timeliness and accuracy of pollution prevention and control.

[0097] On the other hand, referring to Figure 2 It is shown that the present application also provides a river discharge port monitoring and warning system based on Internet of Things, which is used for applying the above-mentioned river discharge port monitoring and warning method based on Internet of Things, and includes:

[0098] The water quality detection sensor is arranged at the discharge port along the river;

[0099] The map generation module is used for drawing the river and discharge port map, and positioning each water quality detection sensor and discharge port, matching the positioning information of the water quality detection sensor with the position of the discharge port;

[0100] The primary warning module is used for collecting the water quality data and positioning information of the water quality detection sensor in real time, transmitting the water quality data and positioning information of the water quality detection sensor to the monitoring platform in real time through the wireless communication module, monitoring whether the sewage discharged from the discharge port meets the standard in real time, and judging whether to give a primary warning to the discharge port;

[0101] The early warning adjustment module is configured to perform primary early warning on the discharge outlet according to the discharge amount of the substandard sewage when the sewage quality is substandard, collect the pollutant concentration of the substandard sewage, and determine whether to adjust the primary early warning level. When it is determined to adjust, the primary early warning level is adjusted according to the pollutant concentration of the substandard sewage.

[0102] The early warning adjustment module is further configured to collect the water flow rate of the river channel, determine whether to perform secondary adjustment on the primary early warning level or the primary early warning level after the first adjustment according to the water flow rate, and perform secondary adjustment on the primary early warning level or the primary early warning level after the first adjustment according to the water flow rate of the river channel when it is determined to perform secondary adjustment.

[0103] The display module is configured to display the adjusted early warning level on the map.

[0104] It can be understood that by integrating the water quality detection sensor, the map generation module, the primary early warning module, the early warning adjustment module, and the display module, comprehensive river discharge outlet monitoring and early warning functions are provided. The system can monitor the water quality of the discharge outlet in real time, and dynamically adjust the early warning level according to the sewage discharge amount, the pollutant concentration, and the river water flow rate. At the same time, the system intuitively displays the adjusted early warning level on the map, helping managers quickly identify pollution risks and make response decisions. This efficient and accurate monitoring mechanism helps improve the timeliness and accuracy of pollution control and protects the health of the river environment.
