Description

Technical Field

[0001] This invention relates to the field of municipal pipeline system technology, specifically to a monitoring system for urban pipeline blockage. Background Technology

[0002] Urban pipeline systems are a key component of urban construction. Primarily utilizing underground pipelines, they are complex in structure and widely distributed. As the city's underground "neural network," urban pipeline systems are mainly used to collect and transport urban runoff, serving to protect urban safety and mitigate urban disasters. During pipeline operation, rainwater runoff often carries large amounts of silt, leaves, and other solid debris into the pipelines, causing siltation and blockages. This leads to a sharp decline in the pipeline's drainage capacity, and in some cases, complete blockage, rendering the pipelines unable to drain rainwater and causing severe urban flooding.

[0003] Currently, methods for monitoring urban pipeline blockages mainly include traditional experience methods, visual inspection methods, sonar detection methods, and liquid level monitoring methods. Traditional experience methods rely on judging road surface water levels and repairing only where water accumulates, primarily depending on manual labor and experience, making it difficult to detect problems promptly, and pipeline cleaning is often delayed. Visual inspection methods mainly use video monitoring equipment inside the pipeline to observe for blockages in real time, but this method has a short monitoring range, high cost, and is difficult to implement on a large scale. Sonar detection methods have a relatively comprehensive detection scope, and the detection work is easily affected by external environmental factors. Liquid level monitoring methods determine whether the pipeline is blocked by changes in the water level, but this method requires the pipeline to be in a water-carrying state, i.e., rainy weather conditions. This makes it, like traditional experience methods, difficult to detect problems and clean up blockages on sunny days, resulting in a certain degree of lag. Currently, except for visual inspection methods, the monitoring results of other systems are either zero or one, i.e., the pipeline is completely blocked or not blocked, lacking monitoring of different degrees of blockage. Therefore, there is an urgent need to build an urban pipeline blockage monitoring system that can monitor pipeline blockage in a timely manner on sunny days, play a corresponding role on rainy days, and requires low manpower. Summary of the Invention

[0004] The technical problem to be solved by this invention is to overcome the shortcomings of the prior art and provide a monitoring system for urban pipeline blockage. Combining the principle of laser linear propagation, this invention utilizes the long-distance signal propagation of laser to design a system that automatically monitors the degree of blockage in urban pipelines and simultaneously monitors the solid content in the pipeline water flow. This solves the problems of short monitoring length, constraints from pipeline conditions, monitoring lag, and single monitoring results in existing municipal pipeline systems.

[0005] To achieve the above objectives, the present invention provides an urban pipeline blockage monitoring system, comprising: a main control console, a display terminal, a data transmission terminal, and a monitoring terminal; wherein,

[0006] The main control console is used to control the start and stop of the entire pipeline blockage monitoring system, and to process and feed back the data uploaded by the data transmission terminal.

[0007] The display terminal is used to display the pipeline information fed back by the main control console, mainly displaying the pipeline blockage level, solid content, and pipeline location;

[0008] The data transmission terminal is used to transmit start / stop commands to the monitoring terminal and upload the recorded information to the main control console.

[0009] The monitoring terminal includes a laser signal transmitter and a signal receiver, which are respectively installed at the pipeline outlet and inlet to monitor the pipeline blockage.

[0010] Furthermore, the data transmission terminal is a router deployed at certain intervals, through which the monitoring terminal is transmitted to enable / disable commands, and the recorded information is uploaded to the main control console.

[0011] Furthermore, the laser signal transmitting end includes a main control chip and a laser transmitter, and the signal receiving end includes a main control chip and a receiving board. The laser transmitter is arranged circumferentially inside the pipe, and the receiving board is arranged on the other side of the pipe according to the corresponding position of the laser transmitter. Each main control chip controls the emission and reception of the laser.

[0012] Furthermore, the laser signal transmitter and the signal receiver also include a waterproof box, which is fixed to the outlet and inlet of the pipe to protect the main control chip, laser transmitter, and receiver board from the underwater environment. The material is a transparent waterproof material, and the top of the waterproof box is streamlined.

[0013] Furthermore, there are seven laser signal transmitters: laser signal transmitter 1, laser signal transmitter 2, laser signal transmitter 3, laser signal transmitter 4, laser signal transmitter 5, laser signal transmitter 6, and laser signal transmitter 7. Laser signal transmitters 1 and 2 are located on both sides of the 25% position of the pipe, laser signal transmitters 3 and 4 are located on both sides of the 50% position of the pipe, laser signal transmitters 5 and 6 are located on both sides of the 75% position of the pipe, and laser signal transmitter 7 is located at the 100% position of the pipe. There are also seven signal receivers: signal receiver 1, signal receiver 2, signal receiver 3, signal receiver 4, signal receiver 5, signal receiver 6, and signal receiver 7, each corresponding to one of the laser signal transmitters.

[0014] Furthermore, the display terminal includes pipeline information display, pipeline blockage level display, and rainy weather pipeline solid content display. The pipeline blockage level display is divided into 5 levels: no blockage, slight blockage, medium blockage, severe blockage, and complete blockage. The rainy weather pipeline solid content display levels are low, relatively low, medium, relatively high, and high. The pipeline information display mainly includes pipeline number, pipeline location, pipeline length, and monitoring time.

[0015] Furthermore, the method for classifying pipe blockage levels is as follows: The laser signal transmitter passes through the entire pipe and hits the receiver. When the pipe is blocked, the laser cannot pass through the pipe, and the receiver cannot receive the laser signal. At this time, the main control chip of the signal receiver records the reception status of the laser by the receiver and uploads the data. On the main control console, according to the set program, the pipe where the receiver does not receive the laser signal is identified as blocked, and the number of the pipe signal receiver is used as the basis for judging the degree of blockage. The degree of pipe blockage is divided into no blockage, slight blockage, medium blockage, severe blockage, and complete blockage.

[0016] Furthermore, the method for judging the solid content in pipeline water flow during rain is as follows: When it rains, rainwater carries a large amount of solids into the pipeline. The solids block the laser signal in the pipeline, preventing the receiving plate at the other end of the pipeline from receiving the laser signal for a certain period of time. As the solids flow out, the receiving plate can receive the laser signal again. The ratio of the duration during which the receiving plate cannot receive the laser signal to the total duration of rainfall is used as the basis for judging the solid content. Considering all the receiving plates located underwater, an average ratio of less than 0.02 is considered to have low solid content, an average ratio of 0.02-0.04 is considered to have relatively low solid content, an average ratio of 0.04-0.06 is considered to have medium solid content, an average ratio of 0.06-0.08 is considered to have relatively high solid content, and an average ratio above 0.08 is considered to have high solid content.

[0017] The beneficial effects of this invention are as follows:

[0018] This invention utilizes the principle of laser linear propagation, deploying laser emitters and receivers at different locations at the inlet and outlet of a pipeline. By analyzing the laser signal reception of the receivers, the degree of blockage in that section of the pipeline can be quickly identified and determined. This allows for timely alerts to staff for dredging and maintenance, ensuring that the pipeline's drainage capacity is not weakened before rainfall. During rainy weather, when the pipeline is draining water, the system can determine the solid content in the rainwater based on the ratio of the duration during which the receivers cannot receive laser signals to the total duration of rainfall. This information can alert staff to the environmental conditions of the area where the pipeline is located, facilitating subsequent environmental remediation. The system is highly economical and widely applicable, providing a monitoring method for urban surface environment monitoring while ensuring urban drainage safety. Attached Figure Description

[0027] like Figures 1-2 As shown, this invention provides a monitoring system for urban pipeline blockage, characterized by comprising: a main control console 1, a display terminal 2, a data transmission terminal 3, and a monitoring terminal 4; wherein,

[0028] The main control console is used to control the start and stop of the entire pipeline blockage monitoring system, and to process and feed back the data uploaded by the data transmission terminal.

[0029] The display terminal is used to display the pipeline information fed back by the main control console, mainly displaying the pipeline blockage level, solid content, and pipeline location;

[0030] The data transmission terminal is a router 31 deployed at certain intervals. The router 31 transmits start / stop commands to the monitoring terminal and uploads the recorded information to the main control console.

[0031] The monitoring terminal includes a laser signal transmitter 41 and a signal receiver 42, which are respectively installed at the outlet and inlet of the pipeline 5 (specifically distributed near the rainwater pipe node 6) to monitor the siltation of the pipeline.

[0032] In this embodiment, the main control console 1 uses a command method to transmit the monitoring start / stop command to the monitoring terminal through the router at the data transmission terminal, thereby controlling the start / stop of the entire pipeline blockage monitoring system, and at the same time processing and feeding back the data uploaded by the data transmission terminal.

[0033] refer to Figure 3 and Figure 4 The laser signal transmitting end includes a main control chip 8, a laser emitter 9, and a waterproof box 10. The main control chip 8 and the laser emitter 9 are electrically connected and both are housed within the waterproof box 10. The signal receiving end includes a main control chip 8, a waterproof box 10, and a receiving board 11. The receiving board 11 and the main control chip are electrically connected and both are housed within the waterproof box 10. The laser emitter 9 is arranged circumferentially inside the pipe (the laser emitters are arranged on both sides of the pipe according to an equal percentage of the pipe, with one located at the top). The receiving board 11 is arranged on the other side of the pipe according to the corresponding position of the laser emitter. Each main control chip controls the emission and reception of the laser. The waterproof box 10 is fixed at the outlet and inlet of the pipe to protect the main control chip, laser emitter, and receiving board from the underwater environment. The material is a transparent waterproof material, and the top of the waterproof box is streamlined.

[0034] In this embodiment, seven laser signal transmitters 41 are provided and connected by power lines. These are designated as laser signal transmitter 1 (411), laser signal transmitter 2 (412), laser signal transmitter 3 (413), laser signal transmitter 414 (414), laser signal transmitter 5 (415), laser signal transmitter 6 (416), and laser signal transmitter 7 (417). Laser signal transmitters 1 and 2 are located on either side of the 25% mark of the pipe, while laser signal transmitters 3 and 4 are located on the pipe 5. At the 0% position, laser signal transmitters No. 5 and No. 6 are located on either side of the 75% position of the pipe, while laser signal transmitter No. 7 is located at the 100% position of the pipe, i.e., the top of the pipe. There are also 7 signal receivers, connected by wires, namely signal receiver No. 1 421, signal receiver No. 2 422, signal receiver No. 3 423, signal receiver No. 424, signal receiver No. 5 425, signal receiver No. 6 426, and signal receiver No. 7 427, which correspond one-to-one with the laser signal transmitters.

[0035] The display terminal includes pipeline information display, pipeline blockage level display, and rainy weather pipeline solid content display. The pipeline blockage level display is divided into 5 levels: no blockage, slight blockage, medium blockage, severe blockage, and complete blockage. The rainy weather pipeline solid content display levels are low, relatively low, medium, relatively high, and high. The pipeline information display mainly includes pipeline number, pipeline location, pipeline length, and monitoring time.

[0036] refer to Figure 5 In this embodiment, the method for classifying pipe blockage levels is as follows: The laser signal from the laser transmitter passes through the entire pipe and reaches the receiver. When the pipe is blocked, the laser cannot pass through the pipe, and the receiver cannot receive the laser signal. At this time, the main control chip of the signal receiver records the laser reception status of the receiver and uploads the data. On the main control console, according to the set program, the pipe where the receiver does not receive the laser signal is identified as blocked, and the blockage level is classified into non-blockage (No. 1 and No. 2), slight blockage (No. 3 and No. 4), medium blockage (No. 5 and No. 6), severe blockage (No. 7), and complete blockage, based on the number of the pipe signal receiver. To prevent misidentification, the program is set to identify the corresponding pipe blockage level only when two receivers at the same horizontal position of the pipe and the receivers below that position simultaneously fail to receive the laser signal (complete blockage is defined as one receiver).

[0037] refer to Figure 6 In this embodiment, the method for judging the solid content in the pipeline water flow during rain is as follows: When it rains, rainwater carries a large amount of solids into the pipeline. The solids block the laser signal in the pipeline, preventing the receiving plate at the other end of the pipeline from receiving the laser signal for a certain period of time. As the solids flow out, the receiving plate can receive the laser signal again. The ratio of the duration during which the receiving plate cannot receive the laser signal to the total duration of rainfall is used as the basis for judging the solid content. Considering all the receiving plates located underwater, an average ratio of less than 0.02 indicates a low solid content, an average ratio of 0.02-0.04 indicates a relatively low solid content, an average ratio of 0.04-0.06 indicates a medium solid content, an average ratio of 0.06-0.08 indicates a relatively high solid content, and an average ratio above 0.08 indicates a high solid content.

[0038] This invention utilizes the principle of laser linear propagation, deploying laser emitters and receivers at different locations at the inlet and outlet of a pipeline. By analyzing the laser signal reception of the receivers, the degree of blockage in that section of the pipeline can be quickly identified and determined. This allows for timely alerts to staff for dredging and maintenance, ensuring that the pipeline's drainage capacity is not weakened before rainfall. During rainy weather, when the pipeline is draining water, the system can determine the solid content in the rainwater based on the ratio of the duration during which the receivers cannot receive laser signals to the total duration of rainfall. This information can alert staff to the environmental conditions of the area where the pipeline is located, facilitating subsequent environmental remediation. The system is highly economical and widely applicable, providing a monitoring method for urban surface environment monitoring while ensuring urban drainage safety.

Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
