Description

Technical Field

[0001] This invention relates to a method and system for removing silt from drainage pipes, belonging to the field of data management technology. Background Technology

[0002] Drainage pipe networks are trenchless systems, primarily comprising stormwater and sewage systems. Stormwater systems include storm drains, gutters, downpipes, and surface runoff diversion channels, consisting of branch pipes, main pipes, and auxiliary structures such as stormwater inspection wells and outlets. They are mainly used to collect and discharge stormwater runoff and industrial wastewater that can be discharged without treatment. Sewage systems encompass building drainage equipment, community sewage networks, and municipal sewage mains, primarily used to collect domestic sewage, industrial wastewater, and other wastewater requiring treatment. In drainage networks, stormwater systems are susceptible to siltation due to dust flowing into the pipes with rainwater. Sewage systems need to receive sewage containing organic solids, which are prone to siltation. Trenchless systems often use interceptor wells to trap sewage. However, even this traditional method of silt removal in trenchless drainage networks can lead to silt blockages due to delayed drainage pressure regulation and insufficient estimated water pressure. Therefore, it is necessary to propose a sludge removal method and system for drainage pipes, addressing the problem that traditional sludge removal methods easily lead to sludge accumulation. Summary of the Invention

[0003] This application provides a method and system for removing silt from drainage pipes, which can solve the problem of silt accumulation in drainage pipe networks.

[0004] This application provides a method for removing sludge from drainage pipes, comprising: A drainage pipe data collection network is established based on the network access application of each signal concentrator. By using the location coordinates uploaded by each information concentrator, a distribution map of the drainage pipes can be obtained; Select a signal concentrator; Invoke the water body fluctuation data and water body suspended turbidity information uploaded by the selected signal concentrator; Analyze information on suspended solids in water bodies to obtain the types and contents of solids in the water. Analyze water body fluctuation data using wave stratification analysis scripts; Based on the analysis results of the wave stratification analysis script, determine whether the direction of water wave fluctuations points towards the direction of the inflow pipe signal concentrator; If the direction of water ripples points towards the direction of the inflow pipe signal concentrator, then the frequency conversion data of the drainage pump is calculated using the type of solid matter in the water, and the frequency conversion data is fed back to the selected signal concentrator. If the direction of water fluctuation does not point towards the direction of the inflow pipe signal concentrator, then the pipeline where the signal concentrator is located will be labeled as unobstructed in the drainage pipe routing diagram. Return to the previous step and select a signal concentrator until all signal concentrators have been selected.

[0005] This application provides a sludge removal system for drainage pipes, comprising: A server for executing the sludge removal method for drainage pipes; The signal concentrator is connected in communication with the server.

[0006] This application relates to a method and system for removing silt from drainage pipelines. By applying for network access for each signal concentrator, a drainage pipeline data collection network is established to achieve pipeline operation data sharing and process collaboration, improve the efficiency of pipeline dredging, monitor key indicators such as water body fluctuation data and suspended solids information in real time, issue alarms in a timely manner, and ensure the safe and stable operation of the drainage system.

[0007] By utilizing the location coordinates uploaded by each information concentrator, a distribution map of the drainage pipes is obtained, providing comprehensive drainage pipe routing data support for pipeline maintenance personnel. This facilitates the analysis of the causes of pipe siltation and the decision-making regarding the dredging of rainwater in stormwater pipes. The comprehensiveness, intelligence, and efficiency of this system support the management and maintenance of the drainage network.

[0008] By calling the water fluctuation data and suspended solids information uploaded by the selected signal concentrator and marking the water fluctuation data and suspended solids information on the drainage pipe routing map, the relevant calculations for dredging detection can be completed quickly and accurately. The frequency and supply water pressure of the drainage pump can be adjusted in a timely manner. The suspended solids information of the water body can be analyzed to obtain the type and content of solids in the water. On the one hand, it can quickly calculate the common siltation locations of sewage-type water bodies. On the other hand, it can adjust the flushing of sewage pipes by rainwater-type water bodies in a timely manner. It can also distinguish the working status of drainage pumps for sewage-type water bodies and rainwater-type water bodies.

[0009] By using wave stratification analysis scripts to analyze water wave data, when a pipe is initially blocked, silt will accumulate at the end of the pipe away from the liquid surface. This will affect the speed of water movement at the end of the pipe away from the liquid surface. By using the difference between the speed of water movement at the liquid surface and the speed of water movement at the end away from the liquid surface, the blockage of the pipe can be accurately and timely determined.

[0010] By using the drainage pipe routing map and the unobstructed label of the pipeline where the signal concentrator is located, a flow channel for rainwater can be formed. Rainwater with low sand and gravel content can flush out silted-up pipes. When the siltation of the pipes is not too severe, the drainage frequency and peak drainage impact of the drainage pump can be controlled to provide sufficient impact water pressure and achieve silt removal.

[0011] Figure 1 This is a flowchart of a method for removing sludge from drainage pipes according to an embodiment of the present invention; Figure 2 This is a structural connection diagram of a sludge removal system for drainage pipes according to an embodiment of the present invention.

[0012] Figure label: 100 - Server; 200 - Signal concentrator. Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] like Figure 1 As shown, the present invention provides a method for removing sludge from drainage pipes, comprising: S100 establishes a drainage pipe data collection network based on the network access application of each signal concentrator.

[0015] S200 uses the location coordinates uploaded by each information concentrator to obtain a distribution map of the drainage pipes. S300, select a signal concentrator.

[0016] S400 calls up the water fluctuation data and suspended solids information uploaded by the selected signal concentrator.

[0017] S500 analyzes information on suspended solids in water bodies to obtain the types and content of solids in the water.

[0018] The S600 uses wave stratification analysis scripts to analyze water wave data.

[0019] S700, based on the analysis results of the wave stratification analysis script, determines whether the direction of water wave fluctuations points in the direction of the inflow pipe signal concentrator.

[0020] S800: If the direction of water fluctuation points towards the direction of the inflow pipe signal concentrator, the frequency conversion data of the drainage pump is calculated using the type of solid matter in the water, and the frequency conversion data is fed back to the selected signal concentrator.

[0021] S900, if the direction of water fluctuation does not point towards the direction of the inflow pipe signal concentrator, then the pipeline where the signal concentrator is located will be marked as unobstructed in the drainage pipe routing diagram.

[0022] S900a, return to the previous step of selecting a signal concentrator until all signal concentrators have been selected.

[0023] Specifically, the signal concentrator is set up near the pipeline. The location coordinates of the signal concentrator can represent the spatial location information of the drainage pump in the pipeline. The signal concentrator can connect to IoT devices. These IoT devices upload the collected water fluctuation data and suspended solids information to the signal concentrator through communication connections. The signal concentrator transmits the water fluctuation data and suspended solids information collected by the IoT devices to the drainage pipe data collection network through the communication link.

[0024] The signal concentrator's communication module receives communication ports opened by the server, ensuring that the signal concentrator can access the server. The signal concentrator and the server can use the MQTT protocol. The signal concentrator actively initiates a connection to the server's domain name and port, forming a network access application. The server uses authentication to ensure the legitimacy of the connection. The concentrator collects equipment data, packages it, and sends it to the server. The server can actively issue commands to adjust the frequency conversion data of the drainage pump.

[0025] This application relates to a method for removing silt from drainage pipelines. By applying for network access for each signal concentrator, a data collection network for drainage pipelines is established, enabling data sharing and process collaboration in pipeline operation, improving the efficiency of pipeline dredging, real-time monitoring of key indicators such as water body fluctuation data and suspended solids information, timely issuance of alarms, and ensuring the safe and stable operation of the drainage system.

[0026] By utilizing the location coordinates uploaded by each information concentrator, a distribution map of the drainage pipes is obtained, providing comprehensive drainage pipe routing data support for pipeline maintenance personnel. This facilitates the analysis of the causes of pipe siltation and the decision-making regarding the dredging of rainwater in stormwater pipes. The comprehensiveness, intelligence, and efficiency of this system support the management and maintenance of the drainage network.

[0027] By calling the water fluctuation data and suspended solids information uploaded by the selected signal concentrator and marking the water fluctuation data and suspended solids information on the drainage pipe routing map, the relevant calculations for dredging detection can be completed quickly and accurately. The frequency and supply water pressure of the drainage pump can be adjusted in a timely manner. The suspended solids information of the water body can be analyzed to obtain the type and content of solids in the water. On the one hand, it can quickly calculate the common siltation locations of sewage-type water bodies. On the other hand, it can adjust the flushing of sewage pipes by rainwater-type water bodies in a timely manner. It can also distinguish the working status of drainage pumps for sewage-type water bodies and rainwater-type water bodies.

[0028] By using wave stratification analysis scripts to analyze water wave data, when a pipe is initially blocked, silt will accumulate at the end of the pipe away from the liquid surface. This will affect the speed of water movement at the end of the pipe away from the liquid surface. By using the difference between the speed of water movement at the liquid surface and the speed of water movement at the end away from the liquid surface, the blockage of the pipe can be accurately and timely determined.

[0029] By using the drainage pipe routing map and the unobstructed label of the pipeline where the signal concentrator is located, a flow channel for rainwater can be formed. Rainwater with low sand and gravel content can flush out silted-up pipes. When the siltation of the pipes is not too severe, the drainage frequency and drainage impact peak of the drainage pump can be controlled to provide sufficient impact water pressure to achieve silt removal.

[0030] In one embodiment of this application, S200 includes: S211, Select an information concentrator.

[0031] S212, Receive the location coordinates uploaded by the selected information concentrator.

[0032] S213, Analyze the position coordinates.

[0033] S214, obtain the location coordinates of the information concentrator itself and the location coordinates of the associated adjacent information concentrators.

[0034] S215, obtain the connection direction between the information concentrator's own position coordinates and the adjacent position coordinates.

[0035] S216 maps the coordinates of adjacent locations to the coordinates of the information concentrator itself.

[0036] Specifically, the adjacent position coordinates are the position coordinates of the associated adjacent information concentrators.

[0037] S217, return to the step of selecting an information concentrator until all information concentrators have been selected.

[0038] Understandably, signal concentrators are installed at trenchless drainage pipes, which are interconnected to form a drainage network. The signal concentrators upload their own location coordinates, which are then linked to the location coordinates of other signal concentrators within the interconnected pipe networks.

[0039] Simply put, the first signal concentrator uploads its own location coordinates. The pipeline where the first signal concentrator is located serves as the water output end and is connected to three water input pipelines: the second, third, and fourth input pipelines. The location coordinates uploaded by the first signal concentrator are linked to the coordinates of the second, third, and fourth input pipelines. By observing the output and input directions of the water bodies, the connection between the concentrator's own location coordinates and those of adjacent locations can be determined. Simultaneously, the pipeline where the first signal concentrator is located can also serve as a water input node, allowing it to interact with other water output pipelines. Using the uploaded, linked location coordinates, the signal concentrator can construct a drainage pipe distribution map within the drainage pipe data collection network.

[0040] By constructing a drainage pipe routing map using the location coordinates of an information concentrator with a mapping relationship, the conduit path for low-silt silt that is flushed out can be quickly determined, which is beneficial for the drainage pumps in pipelines containing low-silt rainwater bodies to respond quickly to call commands.

[0041] In one embodiment of this application, S200 includes: S221 receives the coordinates of each position.

[0042] S222, calls the initial map with coordinate positioning points.

[0043] S223, fit each received location coordinate to the initial map.

[0044] S224, obtain a route map with location coordinates.

[0045] S225, Select a location coordinate on the map.

[0046] S226, based on the mapping of the selected position coordinates, calls each adjacent position coordinate.

[0047] S227, using the location coordinates of the information concentrator itself and the connection points between adjacent location coordinates, generates a directional line between location coordinates.

[0048] S228, return to the previous step and select a location coordinate in the navigation map until all location coordinates have been selected.

[0049] S229, obtain the distribution map of the drainage pipe route.

[0050] Understandably, calling the initial map with coordinate positioning points is usually achieved through the map application programming interface (API). By using an account registered on the map's official website, the API call key can be obtained, thereby enabling the addition of the map.

[0051] Each received location coordinate is sequentially fitted to the initial map using the latitude and longitude coordinate grid. Specifically, a location coordinate is selected, its longitude and latitude information are read, and the corresponding longitude and latitude information is found in the initial map.

[0052] In the routing map, a fitted coordinate point is selected. The coordinate point has the received location coordinate information and several mapping information. Each mapping information contains the direction of the water inflow pipe and the direction of the water outflow pipe corresponding to the coordinate point. Using the mapping information, the selected location coordinates are connected with adjacent location coordinates in the routing map to generate routing lines between location coordinates. The routing lines between location coordinates are a simplified diagram of the pipeline routing.

[0053] Simply put, the first signal concentrator uploads its own location coordinates. The pipeline where the first signal concentrator is located serves as the output end of the water body and is connected to three input pipelines for the water body: the second input pipeline, the third input pipeline, and the fourth input pipeline. The location coordinates uploaded by the first signal concentrator are associated with the coordinates of the second, third, and fourth input pipelines.

[0054] In the routing map, the coordinates of the first signal concentrator need to be connected to the coordinates of the second input pipeline. The coordinates of the first signal concentrator need to be connected to the coordinates of the third input pipeline. The coordinates of the first signal concentrator need to be connected to the coordinates of the fourth input pipeline. The lines connecting the coordinates of the first signal concentrator and the second and third input pipelines represent the routing of the pipelines.

[0055] By connecting the location coordinates of each signal concentrator, a distribution map of the drainage pipes can be formed.

[0056] In one embodiment of this application, S400 includes: S410, retrieve the drainage pipe routing diagram.

[0057] S420, based on the location coordinates of the selected signal concentrator, obtains a map showing the distribution of the signal concentrator along the drainage pipe.

[0058] S430 calls up the water fluctuation data and suspended solids information uploaded by the selected signal concentrator.

[0059] S440, based on timestamps, marks water fluctuation data and suspended solids information on the drainage pipe routing map.

[0060] S450, calls the connection between the information concentrator's own position coordinates and adjacent position coordinates.

[0061] S460, obtains the drainage delivery pipeline and the backup drainage delivery pipeline.

[0062] Understandably, each signal concentrator is located at the end of the drainage pipe and is electrically connected to the drainage pump. The pump's power can be used to dredge the pipe. The signal concentrator can record information about the water flowing through the pipe, such as water velocity fluctuation data and information about suspended solids, including the types and concentrations of suspended solids.

[0063] There are two main types of suspended solids in drainage pipes: rainwater-related solids, such as sand and gravel, and sewage-related solids, such as organic flocculants from domestic waste. When rainwater flows through the area where the drainage pipe is located, it mixes with sand and gravel on the ground and flows into the drainage pipe. When the rainfall volume is large, the sand and gravel content in the rainwater is low, and this type of rainwater can be used to flush away silt. By using timestamps to mark the received water fluctuation data and suspended solids information on the drainage pipe distribution map, the location of the rainwater used for flushing silt can be quickly identified.

[0064] By connecting the location coordinates of the information concentrator in the distribution map with those of adjacent locations, the main drainage pipeline and the backup drainage pipeline can be obtained. Using the main drainage pipeline and the backup drainage pipeline, the pipeline route for rainwater to flush silt from the current pipeline to the destination can be planned.

[0065] In one embodiment of this application, S500 includes: S510 receives information on suspended solids in water.

[0066] S520 analyzes information on suspended solids in water to obtain the content of sand and gravel in the suspended solids.

[0067] S530, determine whether the content of sand and gravel in suspended solids in water is greater than or equal to the rainwater sand and gravel threshold.

[0068] S540, if the content of sand and gravel in the suspended solids of the water body is greater than or equal to the rainwater sand and gravel threshold, then the type of solid matter in the water body is determined to be rainwater solids, and the content of water solid matter in rainwater solids is obtained.

[0069] S550, if the content of sand and gravel in the suspended solids of the water body is less than the rainwater sand and gravel threshold, then the type of solid matter in the water body is determined to be sewage solids, and the content of sewage solids in the water body is obtained.

[0070] Understandably, by utilizing the characteristic that different sand and gravel contents in water bodies alter the dielectric constant, capacitive sand and gravel sensors can quickly determine the sand and gravel content in suspended solids. When the suspended solids consist of sand and gravel, the sand and gravel content is greater than or equal to the rainwater sand and gravel threshold, which is typically 0.75 mg / L. The sand and gravel content in wastewater solids is generally less than 0.05 mg / L.

[0071] Because sewage solids contain a large amount of organic matter, they have a high degree of adhesion, easily causing blockages in pipes. During actual operation, drainage pipes transport different types of water as needed. The content of sand and gravel in the suspended solids can distinguish between rainwater and sewage. Marking the suspended solids information on a drainage pipe routing map allows for timely location of the rainwater pipes used for flushing silt.

[0072] In one embodiment of this application, S600 includes: S610 receives water ripple data uploaded by the selected signal concentrator.

[0073] S620 analyzes water body fluctuation data.

[0074] S630 obtains the water flow velocity at the top and bottom of the water surface in the same pipe cross-section.

[0075] S640 uses a wave stratification analysis script to determine whether the water flow velocity at the top of the water body surface is greater than the water flow velocity at the bottom of the water body surface.

[0076] S650, if the water flow velocity at the top of the water body is greater than the water flow velocity at the bottom of the water body, then the direction of water ripple is determined to be the direction of the inflow pipe signal concentrator.

[0077] S660, if the water flow velocity at the top of the water body is equal to the water flow velocity at the bottom of the water body, then the direction of water ripple does not point in the direction of the inflow pipe signal concentrator.

[0078] Understandably, water flowing through drainage pipes exhibits different flow states depending on the obstructions within the pipes. These different flow states are often represented by water wave data. By analyzing the water wave data uploaded by the signal concentrator, the water flow velocity at the top and bottom of the water surface at the same pipe cross-section can be determined. The wave stratification analysis script is a program script that compares the water flow velocity at the top and bottom of the water surface at the same pipe cross-section.

[0079] The flow velocity at the top of the water body is not significantly hindered by the drain pipe wall, while the flow velocity at the bottom of the water body is significantly hindered by the drain pipe wall.

[0080] When the water flow velocity at the top of the water body is greater than the water flow velocity at the bottom of the water body, it indicates that the water flow at the bottom of the water body is obstructed by silt. In this case, the direction of water ripples points in the direction of the inflow pipe signal concentrator. The direction of water ripples is the direction of the water flow from the bottom of the water body to the top of the water body.

[0081] When the water flow velocity at the top of the water body is equal to the water flow velocity at the bottom of the water body, it means that the water flow at the bottom of the water body is not obstructed by silt. In this state, the direction of water ripples is parallel to the same pipe cross-section, and the direction of water ripples does not point towards the direction of the inflow pipe signal concentrator.

[0082] When the water flow velocity at the top of the water body is less than the water flow velocity at the bottom of the water body, it indicates that the drainage pump is in the dredging working state. The drainage pump adjusts the drainage frequency and drainage pressure to generate shock waves in the water body at the bottom of the water body, impacting the silt in the drainage pipe.

[0083] In one embodiment of this application, S800 includes: S810, based on the type of solid matter in the water body, determine whether the type of solid matter in the water body is rainwater solids.

[0084] S820, if the type of solid matter in the water is rainwater, then adjust the drainage pump to the first frequency and the first peak value.

[0085] S830, if the type of solid matter in the water body is not rainwater solids, then the type of solid matter in the water body is determined to be sewage solids, and the drainage pump is adjusted to the second frequency and the second peak value.

[0086] S840, receives the operating time of the drainage pump.

[0087] S850, based on system time, returns the water body fluctuation data uploaded by the selected signal concentrator.

[0088] S860, obtains water body fluctuation data.

[0089] The S870 uses water wave data to determine whether the direction of water wave is pointing towards the inflow pipe signal concentrator.

[0090] S880, if the direction of water ripples does not point towards the direction of the inflow pipe signal concentrator, then the dredging work is considered complete.

[0091] S890: If the direction of water ripples points in the direction of the inflow pipe signal concentrator, then the water dredging information will be fed back.

[0092] Understandably, adjusting the operating frequency and peak value of the drainage pump can change the movement state of the discharged water, and the sludge in the pipe can be cleaned by using water with different movement states.

[0093] Rainwater-related solids are mainly accumulated sand and gravel; this type of sludge requires a low-frequency, high-peak water flow velocity to impact it. Solids not classified as rainwater-related solids are mainly sewage-related solids, which are mostly highly viscous organic flocculants; this type of sludge requires a high-frequency, low-peak water flow velocity to impact it. When the solids in the water body are rainwater-related solids, the pump speed should be adjusted to the first frequency and the first peak value to achieve a low-frequency, high-peak water flow impact when the water body is discharged. When the solids in the water body are not rainwater-related solids, but sewage-related solids, the pump speed should be adjusted to the second frequency and the second peak value to achieve a low-frequency, high-peak water flow impact when the water body is discharged.

[0094] The drainage pump needs some time to clear silt from its own drainage pipes. The system receives the pump's operating time; after a period of operation, its signal concentrator receives water fluctuation data from its own drainage pipes and repeats steps S610 to S660 to determine if silt still remains inside the pipes.

[0095] If the direction of water ripples does not point towards the direction of the inflow pipe signal concentrator, it indicates that there is no silt inside the pipe itself.

[0096] When the direction of water ripples points towards the direction of the inflow pipe signal concentrator, it indicates that there is still silt inside the pipe and it is necessary to call water with low suspended solids content from other pipes for dredging. At this time, the server will provide feedback on the request for water dredging.

[0097] In one embodiment of this application, S890 includes: S891 receives and calls information on water dredging.

[0098] S892, using the drainage pipe routing map, obtain the location coordinates of the signal concentrator for rainwater-type solids.

[0099] S893, select a rainwater-type solid signal concentrator.

[0100] S894, determine whether the content of sand and gravel in the suspended solids of the selected signal concentrator is less than or equal to the call content threshold.

[0101] S895, if the content of sand and gravel in the suspended solids of the selected signal concentrator is less than or equal to the call content threshold, then assign the call tag to the selected signal concentrator and return to the step of selecting a signal concentrator for rainwater solids, until all signal concentrators for rainwater solids have been selected.

[0102] S896, if the content of sand and gravel in the suspended solids of the selected signal concentrator is greater than the threshold value, then return to the step of selecting a signal concentrator for rainwater solids, until all signal concentrators for rainwater solids have been selected.

[0103] Understandably, by tracing the real-time suspended solids information at each coordinate on the distribution map, the location of water bodies with low suspended solids content can be determined. The threshold for this threshold could be 3 mg / L of suspended solids; water bodies reaching this level are generally rainwater. Water bodies with low suspended solids content can better dissolve silt, improving the efficiency of silt flushing.

[0104] When the content of sand and gravel in the suspended solids of the water in the selected signal concentrator is less than or equal to the call content threshold, the selected signal concentrator will be assigned a call tag. When the target pipe that needs to be dredged is connected to the pipe where the signal concentrator with the call tag is located, the rainwater in the pipe where the signal concentrator with the call tag is located can be used for dredging.

[0105] In one embodiment of this application, S890 further includes: S890a, the location coordinates of the signal concentrator that calls the feedback information on water dredging.

[0106] S890b, select a signal concentrator with a call tag.

[0107] S890c, obtain the position coordinates of the selected signal concentrator.

[0108] S890d marks the location coordinates of the selected signal concentrator and the location coordinates of the signal concentrator that feeds back information on water dredging on the drainage pipe routing diagram.

[0109] S890e, invokes the drainage delivery pipeline and the backup drainage delivery pipeline.

[0110] S890f determines whether there is a connecting pipeline between the location coordinates of the selected signal concentrator and the location coordinates of the signal concentrator that feeds back information on water dredging.

[0111] If there is a connecting pipeline between the selected signal concentrator's location coordinates and the signal concentrator's location coordinates that provide feedback on water dredging information, the S890g will send a command to invoke water dredging.

[0112] S890h, if there is no connecting pipeline between the location coordinates of the selected signal concentrator and the location coordinates of the signal concentrator that feeds back the water dredging information, then return to the step of selecting a signal concentrator with a call tag, until all signal concentrators with call tags have been selected.

[0113] Understandably, the closer the pipe is to the location coordinates of the signal concentrator that provides feedback on water body dredging information, the easier it is to find a connection path and realize the call for rainwater.

[0114] The location coordinates of the signal concentrator that provides feedback on water dredging information can be used as the center of a circle, and a circular diagram can be drawn with radii of 1 km, 3 km, and 5 km to locate the pipeline where the signal concentrator with the call tag is located.

[0115] Simply put, if there is no pipeline with a call tag for a signal concentrator within a circular map with a radius of one kilometer, then a circular map with a radius of three kilometers is used to find the pipeline with the call tag. The pipeline containing the found signal concentrator with the call tag is then selected. Using the drainage transport pipeline between the signal concentrator with the call tag and the signal concentrator that provides feedback on water dredging information, as well as the backup drainage transport pipeline, it can be determined whether there is a connecting transport pipeline between the location coordinates of the selected signal concentrator and the location coordinates of the signal concentrator that provides feedback on water dredging information.

[0116] When there is a connecting pipeline between the location coordinates of the selected signal concentrator and the location coordinates of the signal concentrator that provides feedback on water dredging information, a command to call for water dredging can be sent to each signal concentrator along the pipeline path, so that the signal concentrator can start the drainage pump.

[0117] like Figure 2 As shown, the present invention provides a sludge removal system for drainage pipes, including a server 100 and a signal concentrator 200.

[0118] The server 100 is used to execute the sludge removal method for drainage pipes.

[0119] The signal concentrator 200 is communicatively connected to the server 100.

[0120] This embodiment relates to a sludge removal system for drainage pipelines. The server 100 establishes a drainage pipeline data collection network through the network access application of each signal concentrator 200, realizes pipeline operation data sharing and process collaboration, improves the efficiency of pipeline sludge removal, monitors key indicators of water body fluctuation data and suspended solids information in real time, issues alarms in a timely manner, and ensures the safe and stable operation of the drainage system.

[0121] By utilizing the location coordinates uploaded by each signal concentrator 200, a distribution map of the drainage pipes is obtained, providing comprehensive drainage pipe routing data support for pipeline maintenance personnel. This facilitates the analysis of the causes of pipe siltation and the decision-making regarding the dredging of rainwater in stormwater pipes. The comprehensiveness, intelligence, and efficiency of this system support the management and maintenance of the drainage network.

[0122] Server 100 calls the water fluctuation data and suspended solids information uploaded by the selected signal concentrator 200, and marks the water fluctuation data and suspended solids information on the drainage pipe distribution map. It can quickly and accurately complete the relevant calculations for dredging detection, adjust the frequency and supply water pressure of the drainage pump in a timely manner, and analyze the suspended solids information to obtain the type and content of solids in the water. On the one hand, it can quickly calculate the common siltation locations of sewage-type water bodies, and on the other hand, it can adjust the flushing of sewage pipes by rainwater-type water bodies in a timely manner. It can also distinguish the working status of drainage pumps for sewage-type water bodies and rainwater-type water bodies.
