It should be noted that, in the absence of conflict, the embodiments of the present invention and the features 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 conjunction with the implementation regulations.
[0047] See also Figure 1 As shown, in some embodiments of the present application, this embodiment provides a monitoring system for urban drainage pipes, including:
[0048] A plurality of sensor groups, each of which is disposed in different monitoring areas of the drainage pipe, and is used to collect flow data and environmental data in each monitoring area;
[0049] A storage module is configured to establish a historical database, wherein the historical database includes historical traffic data and historical environmental data;
[0050] A collection module is configured to collect flow data in each monitoring area to establish a flow data set, and obtain a comprehensive flow change rate of the drainage pipe according to the flow data set;
[0051] The judgment module is configured to compare the comprehensive flow rate change rate with the comprehensive flow rate change rate threshold, and judge whether the drainage pipe has an abnormality according to the comparison result; when it is determined that the drainage pipe has an abnormality, control the acquisition module to collect the regional flow rate change rate of each of the monitoring areas, and compare the regional flow rate change rate with the regional flow rate change rate threshold, determine the number of areas of the monitoring area whose regional flow rate change rate is less than the regional flow rate change rate threshold according to the comparison result, compare the area number with the area number threshold, and judge the regional abnormality of the drainage pipe according to the comparison result;
[0052] a verification module configured to, when verifying the regional anomaly of the drainage pipe, control the acquisition module to acquire environmental data of the monitoring area and calculate an environmental score value corresponding to the environmental data, compare the environmental score value with an environmental score threshold, and verify the regional anomaly of the drainage pipe according to the comparison result;
[0053] The early warning module is configured to compare the environmental data with the historical database when it is determined that the area of the drainage pipe is abnormal, and to issue an early warning to the drainage pipe according to the comparison result.
[0054] It can be seen that the monitoring system for urban drainage pipes provided by this embodiment can monitor the operation status of drainage pipes in real time, discover potential problems in time, ensure the accuracy and reliability of early warning, and thus ensure the safe operation of urban drainage systems through the coordinated cooperation of the sensor group, the acquisition module, the judgment module, the verification module, and the early warning module. In addition, the monitoring system of the present invention also has self-learning and adaptive capabilities, and can continuously optimize the early warning mechanism based on the analysis results of historical data and real-time data to improve the accuracy and efficiency of monitoring.
[0055] Specifically, the flow data includes real-time flow, cumulative flow, water flow velocity and water flow level; the environmental data includes temperature data inside the drainage pipe and temperature data outside the drainage pipe.
[0056] Specifically, when the comprehensive flow rate change rate of the drainage pipe is obtained according to the flow data set, the comprehensive flow rate change rate formula is obtained by the following formula:
[0057]
[0058] Among them, CR represents the comprehensive flow rate change rate, CR 1 Indicates the pipeline flow rate change rate, CR 2 Indicates the rate of change of pipeline flow velocity, CR 3 It represents the rate of change of pipe water level, Fcurrent represents the real-time flow rate, Favg represents the historical average flow rate at the corresponding time, Vcurrent represents the real-time water flow velocity, Vavg represents the historical average water flow velocity at the corresponding time, Hcurrent represents the real-time water flow level, and Havg represents the historical average water flow level at the corresponding time.
[0059] It is understood that the historical average flow refers to the average value of the flow data collected by the monitoring system within a certain time period, such as a month or a quarter. This average value reflects the average flow level of the drainage pipe in the monitoring area during the time period under normal circumstances. The historical average water flow velocity and the historical average water flow level refer to the average values of the water flow velocity and water flow level collected by the monitoring system in a similar time period. These average values provide important reference data for the monitoring system to evaluate whether the current flow change exceeds the normal range. When the real-time flow, water flow velocity or water flow level is significantly different from the historical average, the system will calculate the comprehensive flow change rate to determine whether there is an abnormality in the drainage pipe.
[0060] Specifically, the comprehensive flow rate change rate is compared with the comprehensive flow rate change rate threshold, and judging whether the drainage pipe is abnormal according to the comparison result includes:
[0061] When the comprehensive flow rate change rate is less than the comprehensive flow rate change rate threshold, the judgment module determines that there is no abnormality in the drainage pipe;
[0062] When the comprehensive flow rate change rate is greater than or equal to the comprehensive flow rate change rate threshold, the judgment module determines that there is an abnormality in the drainage pipe.
[0063] It is understandable that the threshold of the comprehensive flow rate change rate is set based on expert experience to distinguish the boundary between normal flow fluctuations and abnormal flow fluctuations. In practical applications, this threshold can be adjusted according to the specific conditions and historical operation data of drainage pipes in different cities to improve the adaptability and accuracy of the monitoring system.
[0064] Specifically, the area number is compared with the area number threshold, and when the area abnormality of the drainage pipe is determined according to the comparison result, it includes:
[0065] Comparing the area quantity with the area quantity threshold, and determining the area abnormality of the drainage pipe according to the comparison result;
[0066] When the number of regions is less than the region number threshold, the judgment module preliminarily determines that the regional abnormality of the drainage pipe is abnormal leakage or siltation, and verifies the regional abnormality of the drainage pipe;
[0067] When the area number is greater than or equal to the area number threshold, the judgment module determines that the area abnormality of the drainage pipe is leakage or siltation abnormality, directly issues an alarm for the drainage pipe area, and performs manual verification.
[0068] It is understandable that the area number threshold is set based on historical data and expert experience to determine the degree of abnormal leakage or siltation. In actual applications, this threshold can be adjusted according to the characteristics of different drainage pipes and historical operation data to ensure the accuracy and reliability of the monitoring system. When the area number is less than the area number threshold, it may mean that there are local leakage or siltation problems in the drainage pipe, which may require further verification and observation. When the area number is greater than or equal to the area number threshold, it may indicate that there are more serious leakage or siltation problems in the drainage pipe, which requires immediate alarm and manual verification to avoid greater impact on the urban drainage system.
[0069] Specifically, when the judgment module preliminarily determines that the regional abnormality of the drainage pipe is abnormal leakage or siltation, and verifies the regional abnormality of the drainage pipe, it includes:
[0070] Collecting environmental data in the monitoring area and calculating an environmental score value corresponding to the environmental data, comparing the environmental score value with an environmental score threshold, and verifying regional anomalies of the drainage pipe according to the comparison result;
[0071] The environmental score is obtained by the following formula:
[0072]
[0073] Wherein, S represents the environmental score value, ΔT represents the temperature difference between the internal temperature data and the external temperature data, Tmax represents the standard temperature difference between the internal temperature data and the external temperature data, and ω1 represents the first weight coefficient.
[0074] It can be understood that the environmental score value S is an indicator for comprehensively evaluating the internal environmental conditions of the drainage pipe. When the difference between the internal temperature and the external temperature exceeds the normal range, this difference value will be used to calculate the environmental score value. The standard temperature difference value Tmax is set based on historical data and expert experience to distinguish the boundary between normal temperature differences and abnormal temperature differences. The first weight coefficient ω1 reflects the importance of temperature differences in evaluating environmental conditions. By calculating the environmental score value and comparing it with the set environmental score threshold, it can be further verified whether the regional anomaly of the drainage pipe does have abnormal leakage or siltation problems.
[0075] Specifically, when it is determined that the drainage pipe is abnormal in a certain area, the environmental data is compared with the historical database, and an early warning is issued to the drainage pipe according to the comparison result, including:
[0076] When the same environmental data exists in the historical database, the environmental data is updated to the historical database and an early warning is issued according to the frequency of occurrence of the data;
[0077] When the same environmental data does not exist in the historical database, the environmental data is updated to the historical database and an alarm is issued to remind manual verification.
[0078] It is understandable that the establishment of the historical database is to accumulate and analyze the operation data of the drainage pipes under different environmental conditions, so as to more accurately predict and identify potential problems in the future. By continuously updating the historical database, the system can learn and adapt to various environmental changes, thereby improving the accuracy and timeliness of early warnings. When the environmental data matches the data in the historical database, the system will determine the level of early warning based on the frequency of data occurrence. If the frequency of data occurrence is high, indicating that the abnormal situation under the environmental conditions is more common, the system will issue a corresponding early warning signal so that maintenance personnel can pay attention and take measures in time. On the contrary, if the environmental data appears for the first time in the historical database, the system will issue an alarm signal to prompt the maintenance personnel to conduct manual verification to ensure timely response to unknown or rare abnormal situations. Such a mechanism ensures the intelligence and automation level of the monitoring system, while reducing the risk of false alarms and missed alarms, and improving the overall maintenance efficiency and reliability of the urban drainage system.
[0079] Specifically, when the same environmental data exists in the historical database, updating the environmental data to the historical database and issuing an early warning according to the frequency of occurrence of the data includes:
[0080] When the number of environmental data occurrences reaches the first preset number, a first-level warning is issued;
[0081] When the number of environmental data occurrences is greater than the first preset number and less than or equal to the second preset number, a second-level warning is issued;
[0082] When the number of occurrences of environmental data is greater than the second preset number, a third-level warning is issued and an alarm is sounded to remind manual verification.
[0083] It is understandable that the first preset number and the second preset number are set based on the statistical analysis of historical data to distinguish different levels of warnings. For example, the first preset number may be set to 5 times, which means that when specific environmental data appears 5 times, the system will issue a first-level warning; the second preset number may be set to 10 times, which means that when specific environmental data appears more than 5 times but not more than 10 times, the system will issue a second-level warning. In this way, the system can provide different levels of warning information based on the frequency and historical trends of environmental data, thereby helping maintenance personnel to prioritize potential problems and respond in a timely manner. This hierarchical warning mechanism not only improves the intelligence level of the monitoring system, but also ensures the effective allocation of maintenance resources, further enhancing the stability and safety of the urban drainage system.
