Description

Technical Field

[0001] The present invention relates to the field of river channel monitoring technology, and in particular to a river channel discharge outlet monitoring and early warning method and system based on the Internet of Things. Background Art

[0002] With the rapid development of social economy and the acceleration of urbanization, the discharge of industrial wastewater, domestic sewage and agricultural runoff has increased significantly, leading to increasingly serious water pollution problems. As an important part of water resources, rivers not only bear the function of urban drainage, but also provide protection for agricultural, industrial and domestic water. However, the existence of illegal discharge outlets and insufficient monitoring of sewage discharge have greatly affected the health of the water environment and even threatened the safety of humans and ecosystems.

[0003] Traditional river discharge outlet monitoring methods usually rely on manual inspections and regular sampling and analysis. However, this method has the disadvantages of long cycles, large workloads, high costs, and poor real-time performance. It is unable to detect the occurrence of illegal discharges in a timely and accurate manner, especially unable to effectively warn and handle sudden pollution incidents. In addition, the warning mechanism in the existing technology is usually single and difficult to accurately reflect the pollution situation, resulting in low management efficiency and the inability to quickly take corresponding measures to prevent the spread of pollution.

[0004] Therefore, it is necessary to provide a river discharge outlet monitoring and early warning method and system based on the Internet of Things to solve the problem that river discharge outlet monitoring in the existing technology is difficult to accurately reflect the pollution situation and provide accurate early warning. Summary of the invention

[0005] In view of this, the present invention proposes a river discharge outlet monitoring and early warning method and system based on the Internet of Things, aiming to solve the problem in the prior art that river discharge outlet monitoring is difficult to accurately reflect the pollution situation and provide precise early warning.

[0006] On the one hand, the present invention proposes a river discharge outlet monitoring and early warning method based on the Internet of Things, comprising:

[0007] Draw a map of the river and the discharge outlets, set water quality detection sensors and flow meters at the discharge outlets along the river, and locate each of the water quality detection sensors and discharge outlets, and match the location information of the water quality detection sensors with the location of the discharge outlets;

[0008] 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 the monitoring platform in real time through the wireless communication module, monitor in real time whether the quality of sewage discharged from the discharge port meets the standard, and determine whether to issue a primary warning to the discharge port;

[0009] When the sewage quality does not meet the standards, a primary warning is issued to the discharge outlet according to the discharge volume of the sewage that does not meet the standards, the pollutant concentration of the sewage that does not meet the standards is collected, and it is determined whether to adjust the primary warning level. When it is determined to be adjusted, the primary warning level is adjusted by one level according to the pollutant concentration of the sewage that does not meet the standards;

[0010] Collect the water velocity of the river, and determine whether to make a secondary adjustment to the primary warning level or the primary warning level after the primary adjustment according to the water velocity; when it is determined that a secondary adjustment is needed, make a secondary adjustment to the primary warning level or the primary warning level after the primary adjustment according to the water velocity of the river;

[0011] The adjusted warning level is displayed on the map.

[0012] Furthermore, the drawing of the river channel and the discharge outlet map, setting water quality detection sensors and flow meters at the discharge outlets along the river channel, and positioning each of the water quality detection sensors and the discharge outlets, and matching the positioning information of the water quality detection sensors with the position of the discharge outlets, includes:

[0013] Collect the geographical data of the river channel, including the shape, direction and discharge outlet of the river channel, through the use of geographic information system technology, and build a river channel and discharge outlet map in combination with remote sensing data, in which each discharge outlet is marked according to its location;

[0014] The water quality detection sensors are arranged on each discharge port, and the water quality detection sensors are positioned using a global positioning system so that the position information of each water quality detection sensor matches the discharge port corresponding to it.

[0015] Furthermore, the real-time monitoring of whether the sewage quality discharged from the discharge port meets the standard and determining whether to issue a primary warning to the discharge port include:

[0016] When the sewage discharged from the discharge port is detected by the water quality detection sensor and the detection result is not up to standard, it is determined that the discharge port is given a primary warning;

[0017] When the detection result is up to standard, it is determined that no primary warning is issued for the discharge outlet.

[0018] Furthermore, when the sewage quality does not meet the standards, a primary warning is given to the discharge outlet according to the discharge volume of the sewage that does not meet the standards, including:

[0019] A discharge volume range is preset, and if the discharge volume of the substandard sewage is less than the minimum value of the discharge volume range, a first-level warning is issued to the discharge port;

[0020] If the discharge volume of the substandard sewage is greater than or equal to the minimum value of the discharge volume range, and the discharge volume of the substandard sewage is less than or equal to the maximum value of the discharge volume range, a secondary warning is issued for the discharge port;

[0021] If the discharge volume of the substandard sewage is greater than the maximum value of the discharge volume range, a third-level warning is issued to the discharge port;

[0022] Among them, the warning levels from weak to strong are level one warning, level two warning and level three warning.

[0023] Furthermore, the pollutant concentration of the sewage that does not meet the standards is collected, and the determination of whether to adjust the primary warning level includes:

[0024] The pollutants include ammonia nitrogen, total nitrogen and chemical oxygen demand;

[0025] Set maximum pollutant concentrations, including maximum ammonia nitrogen concentration, maximum total nitrogen concentration, and maximum chemical oxygen demand concentration;

[0026] If the concentration of each pollutant is less than the maximum concentration of the pollutant, it is determined that the primary warning level will not be adjusted;

[0027] If there is a pollutant concentration greater than the corresponding maximum pollutant concentration, it is determined that the primary warning level should be adjusted.

[0028] Furthermore, if there is a pollutant concentration greater than the corresponding maximum pollutant concentration, the primary warning level is adjusted, including:

[0029] If there is a pollutant concentration greater than the corresponding maximum pollutant concentration, it is determined that the intensity of the primary warning level is increased by one level;

[0030] If there are two pollutant concentrations greater than their corresponding maximum pollutant concentrations, the intensity of the primary warning level is determined to be increased by two levels;

[0031] If there are three pollutant concentrations greater than their corresponding maximum pollutant concentrations, it is determined that the intensity of the primary warning level is increased by three levels.

[0032] Furthermore, the water flow velocity of the river is collected, and when judging whether to make a secondary adjustment to the primary warning or the primary warning level after the primary adjustment according to the water flow velocity, it includes:

[0033] A minimum water flow velocity is preset, and if the water flow velocity is less than the minimum water flow velocity, it is determined that the primary warning level or the primary warning level after the first-level adjustment is not to be adjusted at the second level;

[0034] If the water flow rate is greater than or equal to the minimum water flow rate, it is determined that a secondary adjustment is required for the primary warning level or the primary warning level after the primary adjustment.

[0035] Furthermore, when it is determined that a secondary adjustment is required, the primary warning level or the primary warning level after the primary adjustment is adjusted at a secondary level according to the flow velocity of the river, including:

[0036] A maximum water flow velocity is preset. If the water flow velocity is greater than or equal to the minimum water flow velocity, and the water flow velocity is less than or equal to the minimum water flow velocity, the primary warning level or the warning level after one adjustment is increased by one level;

[0037] If the water flow rate is greater than the maximum water flow rate, the intensity of the primary warning level or the warning level after one adjustment will be increased by two levels.

[0038] Furthermore, the step of displaying the adjusted warning level on the map includes:

[0039] Mark the final warning level of each outlet with different colors or symbols on the outlet map of the river;

[0040] When the warning level changes, the warning level of the corresponding discharge outlet on the map, the real-time water quality data of the water quality detection sensor, the pollutant concentration data, the sewage discharge data, the water flow rate and other information are automatically updated.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] By mapping the river and the outlets and accurately positioning the water quality detection sensors, real-time monitoring of each outlet is ensured. The water quality detection sensors continuously collect water quality data and transmit it to the monitoring platform through the wireless communication module, ensuring that managers can keep track of the discharge of the outlets at any time and promptly identify whether the sewage meets the standards. When it is found that the sewage does not meet the standards, a primary warning is issued based on the discharge volume and pollutant concentration of the sewage, and the warning level is dynamically adjusted according to the concentration changes. In addition, the introduction of the flow rate of the river water body can further adjust the warning level according to the flow of the water body, making the warning mechanism more intelligent and flexible. Finally, all adjusted warning information will be displayed on the map in real time, and managers can see the status of each outlet at a glance, so that they can take corresponding measures in time, thereby effectively preventing the spread of pollution and ensuring the health of the river's ecological environment.

[0043] On the other hand, the present application also provides a river discharge outlet monitoring and early warning system based on the Internet of Things, including:

[0044] Water quality detection sensors are installed at discharge outlets along the river;

[0045] A map generation module, used to draw a map of the river and the discharge outlet, and locate each of the water quality detection sensors and the discharge outlet, and match the positioning information of the water quality detection sensor with the position of the discharge outlet;

[0046] A primary warning module is used to 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 the monitoring platform in real time through the wireless communication module, monitor in real time whether the quality of sewage discharged from the discharge port meets the standard, and determine whether to issue a primary warning to the discharge port;

[0047] An early warning adjustment module is used to, when the sewage quality does not meet the standard, issue a primary early warning to the discharge port according to the discharge volume of the sewage that does not meet the standard, collect the pollutant concentration of the sewage that does not meet the standard, and determine whether to adjust the primary early warning level. When it is determined to be adjusted, the primary early warning level is adjusted by one level according to the pollutant concentration of the sewage that does not meet the standard;

[0048] The warning adjustment module is also used to collect the water flow velocity of the river, and determine whether to make a secondary adjustment to the primary warning or the primary warning level after the primary adjustment according to the water flow velocity. When it is determined that a secondary adjustment is needed, the primary warning level or the primary warning level after the primary adjustment is made a secondary adjustment according to the water flow velocity of the river;

[0049] The display module is used to display the adjusted warning level on the map.

[0050] It can be understood that the river discharge outlet monitoring and early warning method and system based on the Internet of Things provided in this application have the same beneficial effects and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein.

It should be noted that, in the absence of conflict, the embodiments of the present invention and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

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

[0056] S100, drawing a map of the river and the discharge outlet, setting water quality detection sensors and flow meters at the discharge outlets along the river, and positioning each water quality detection sensor and discharge outlet, and matching the positioning information of the water quality detection sensor with the position of the discharge outlet;

[0057] S200, collecting 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 through the wireless communication module in real time, monitoring in real time whether the sewage quality discharged from the discharge port meets the standard, and determining whether to issue a primary warning to the discharge port;

[0058] S300, when the sewage quality does not meet the standards, a primary warning is issued to the discharge outlet according to the discharge volume of the sewage that does not meet the standards, the pollutant concentration of the sewage that does not meet the standards is collected, and it is determined whether to adjust the primary warning level. If it is determined to be adjusted, the primary warning level is adjusted by one level according to the pollutant concentration of the sewage that does not meet the standards;

[0059] S400, collecting the water flow velocity of the river, judging whether to make a secondary adjustment to the primary warning level or the primary warning level after the primary adjustment according to the water flow velocity, and when judging that a secondary adjustment is needed, making a secondary adjustment to the primary warning level or the primary warning level after the primary adjustment according to the water flow velocity of the river;

[0060] S500. Display the adjusted warning level on a map.

[0061] It is understandable that by mapping the river and the outlets and accurately positioning the water quality detection sensors, real-time monitoring of each outlet is ensured. The water quality detection sensors continuously collect water quality data and transmit it to the monitoring platform through the wireless communication module, ensuring that managers can grasp the discharge of sewage at the outlets at any time and promptly identify whether the sewage meets the standards. When it is found that the sewage does not meet the standards, a primary warning is issued based on the discharge volume and pollutant concentration of the sewage, and the warning level is dynamically adjusted according to the concentration changes. In addition, the introduction of the flow rate of the river water body can further adjust the warning level according to the flow of the water body, making the warning mechanism more intelligent and flexible. Finally, all adjusted warning information will be displayed on the map in real time, and managers can see the status of each outlet at a glance, so as to take corresponding measures in time, thereby effectively preventing the spread of pollution and ensuring the health of the river ecological environment.

[0062] Specifically, the discharge outlet in the present invention refers to the discharge outlet after sewage treatment; whether the sewage quality is up to 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 a river channel and a discharge outlet is drawn, a water quality detection sensor and a flow meter are set at the discharge outlet along the river channel, and each water quality detection sensor and discharge outlet is positioned, and the positioning information of the water quality detection sensor is matched with the position of the discharge outlet, including:

[0064] Collect the geographical data of the river channel, including the shape, direction and discharge outlet of the river channel, through the use of geographic information system technology, and build a river channel and discharge outlet map in combination with remote sensing data, in which each discharge outlet is marked according to its location;

[0065] The water quality detection sensors are arranged at each discharge port, and the water quality detection sensors are positioned using a global positioning system so that the position information of each water quality detection sensor matches its corresponding discharge port.

[0066] It is understandable that by collecting the geographic data of the river through the geographic information system and remote sensing technology, and combining the global positioning system to accurately locate the water quality detection sensors and discharge outlets, it is possible to achieve refined management of the river and discharge outlets, ensure that the location of the discharge outlet accurately matches the positioning information of the sensor, and help improve the coverage and accuracy of sewage monitoring, so that managers can obtain water quality data from each discharge outlet in a timely manner. At the same time, the combination of geographic data and remote sensing information can draw an accurate map of the river, providing a visual basis for subsequent sewage discharge monitoring and early warning, greatly improving the efficiency and accuracy of water quality monitoring.

[0067] In some embodiments of the present application, real-time monitoring of whether the quality of sewage discharged from the discharge port meets the standard and determining whether to issue a primary warning to the discharge port include:

[0068] When the sewage discharged from the discharge port is detected by the water quality detection sensor and the test result is not up to standard, a primary warning is issued to the discharge port;

[0069] When the test results are up to standard, it is determined that no primary warning will be issued for the discharge outlet.

[0070] In some embodiments of the present application, when the sewage quality does not meet the standards, a primary warning is given to the discharge outlet according to the discharge volume of the sewage that does not meet the standards, including:

[0071] The discharge volume range is pre-set. If the discharge volume of substandard sewage is less than the minimum value of the discharge volume range, a first-level warning will be issued to the discharge port;

[0072] If the discharge volume of substandard sewage is greater than or equal to the minimum value of the discharge volume range, and the discharge volume of substandard sewage is less than or equal to the maximum value of the discharge volume range, a secondary warning will be issued for the discharge outlet;

[0073] If the discharge volume of substandard sewage exceeds the maximum value of the discharge volume range, a three-level warning will be issued to the discharge outlet;

[0074] Among them, the warning levels from weak to strong are level one warning, level two warning and level three warning.

[0075] It is understandable that by real-time monitoring of the quality of sewage discharged from the discharge port, it is possible to quickly determine whether an early warning is needed, and to give graded early warnings based on the amount of sewage discharged, effectively improving the sensitivity and accuracy of sewage monitoring. The graded early warning sets thresholds according to the amount of sewage discharged, and gradually increases the intensity of early warnings from level one to level three, ensuring that minor discharge problems are dealt with in a timely manner, while serious pollution triggers higher-level alarms, prompting managers to take quick countermeasures. This dynamically adjusted early warning system can more reasonably reflect the degree of pollution, prevent environmental deterioration, and improve monitoring and management efficiency.

[0076] In some embodiments of the present application, when collecting the pollutant concentration of the sewage that does not meet the standards and determining whether to adjust the primary warning level, the process includes:

[0077] Pollutants include ammonia nitrogen, total nitrogen and chemical oxygen demand;

[0078] Set maximum pollutant concentrations, including maximum ammonia nitrogen concentration, maximum total nitrogen concentration, and maximum chemical oxygen demand concentration;

[0079] If the concentration of each pollutant is less than the maximum pollutant concentration, it is determined that no adjustment will be made to the primary warning level;

[0080] If there is a pollutant concentration greater than the corresponding maximum pollutant concentration, it will be 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, it is determined that the primary warning level is adjusted, including:

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

[0083] If the concentrations of two pollutants are greater than the maximum concentrations of their corresponding pollutants, the primary warning level will be increased by two levels;

[0084] If the concentrations of three pollutants are greater than the corresponding maximum pollutant concentrations, the intensity of the primary warning level will be increased by three levels.

[0085] It is understandable that by real-time monitoring and graded judgment of the concentrations of pollutants such as ammonia nitrogen, total nitrogen and chemical oxygen demand in substandard sewage, more refined early warning adjustments have been achieved. When the concentration of pollutants exceeds the preset maximum value, the warning level is gradually increased according to the number of pollutants exceeding the standard to ensure the accuracy and timeliness of the warning. It can not only effectively distinguish the degree of pollution, but also conduct a comprehensive assessment of multiple pollutants, so as to quickly respond to different degrees of water quality deterioration, help managers take corresponding measures in time, avoid the expansion of environmental problems, and improve water quality management efficiency.

[0086] In some embodiments of the present application, when collecting the water flow velocity of a river and determining whether to make a secondary adjustment to a primary warning or a primary warning level after a primary adjustment according to the water flow velocity, the method includes:

[0087] A minimum water flow velocity is preset. If the water flow velocity is less than the minimum water flow velocity, it is determined that no secondary adjustment will be made to the primary warning level or the primary warning level after the first-level adjustment;

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

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

[0090] The maximum water flow velocity is preset. If the water flow velocity is greater than or equal to the minimum water flow velocity, and the water flow velocity is less than or equal to the minimum water flow velocity, the intensity of the primary warning level or the warning level after one adjustment is increased by one level;

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

[0092] It is understandable that by collecting the flow velocity of the river water body and making a secondary adjustment to the primary warning level or the warning level after the first level adjustment according to the change of the water flow velocity, the accuracy of the early warning system is improved. When the water flow velocity is faster, pollutants may spread more quickly. At this time, raising the warning level can respond to the risk of pollution spread in a timely manner; when the water flow velocity is slower, there is no need to further adjust the warning level, avoiding unnecessary warning upgrades, fully considering the impact of river water flow changes on pollution spread, and can more effectively reflect the actual water quality conditions and improve the efficiency and reliability of river pollution monitoring.

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

[0094] Mark the final warning level of each outlet with different colors or symbols on the outlet map of the river;

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

[0096] It is understandable that by marking the final warning level of each discharge port with different colors or symbols on the map, and automatically updating the map information when the warning level changes, intuitive and dynamic river pollution monitoring is achieved. Managers can quickly identify high-risk discharge ports through the map and take timely countermeasures. At the same time, the real-time display of water quality data, pollutant concentration, discharge volume, water flow rate and other information enhances transparency and decision-making efficiency, helps to more accurately analyze pollution sources and their impact on the river environment, and improves the timeliness and accuracy of pollution prevention and control.

[0097] On the other hand, see Figure 2 As shown, the present application also provides a river discharge outlet monitoring and early warning system based on the Internet of Things, which is used to apply the above-mentioned river discharge outlet monitoring and early warning method based on the Internet of Things, including:

[0098] Water quality detection sensors are installed at discharge outlets along the river;

[0099] A map generation module is used to draw a map of the river and the discharge outlet, and locate each water quality detection sensor and the discharge outlet, and match the location information of the water quality detection sensor with the location of the discharge outlet;

[0100] The primary warning module is used to collect water quality data and positioning information of water quality detection sensors in real time, transmit the water quality data and positioning information of water quality detection sensors to the monitoring platform through the wireless communication module in real time, monitor in real time whether the sewage quality discharged from the discharge port meets the standards, and determine whether to issue a primary warning to the discharge port;

[0101] The early warning adjustment module is used to issue a primary early warning to the discharge port according to the discharge volume of the sewage that does not meet the standards when the sewage quality does not meet the standards, collect the pollutant concentration of the sewage that does not meet the standards, and determine whether to adjust the primary early warning level. If it is determined to be adjusted, the primary early warning level is adjusted by one level according to the pollutant concentration of the sewage that does not meet the standards;

[0102] The warning adjustment module is also used to collect the water flow velocity of the river, and determine whether to make a secondary adjustment to the primary warning or the primary warning level after the primary adjustment according to the water flow velocity. When it is determined that a secondary adjustment is needed, the primary warning level or the primary warning level after the primary adjustment is made a secondary adjustment according to the water flow velocity of the river;

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

[0104] It is understandable that by integrating water quality detection sensors, map generation modules, primary warning modules, warning adjustment modules and display modules, a full range of river discharge outlet monitoring and warning functions is provided. The system can monitor the water quality of the discharge outlet in real time and dynamically adjust the warning level according to the sewage discharge volume, pollutant concentration and river water flow rate. At the same time, the system will intuitively display the adjusted warning level on the map to help managers quickly identify pollution risks and make response decisions. This efficient and accurate monitoring mechanism helps to improve the timeliness and accuracy of pollution control and ensure the health of the river environment.
