Technical Field
[0001] The present invention relates to the technical field of pipeline fault locating, and in particular to a method and system for locating a fault of an underground audio acquisition module. Background Art
[0002] With the development of science and technology, the number of underground water pipes (such as water pipes) in cities is increasing day by day. A large number of underground water pipes with complex patterns need to locate the leak point in time when leaks occur to avoid water leakage losses. At present, the location of the leak point of the buried pipe is a difficult problem in the industry, and there is no universal solution. Especially for the leakage of water pipes, if it is not located and repaired in time, a large amount of water resources will be wasted. One of the detection schemes for underground pipeline leakage points is: install the audio acquisition module at various places of the underground pipeline, and then locate the leakage position of the underground pipeline by analyzing the sound signals of each audio acquisition module. Because most pipelines are buried underground, and the audio acquisition module is installed in the pipeline, when the audio acquisition module fails, it is difficult to locate the faulty audio acquisition module in time and accurately, and repair it in time.

[0060] Figure 1 This is a flowchart of a first embodiment of a method for locating a fault of an underground audio acquisition module proposed by the present invention. DETAILED DESCRIPTION
[0061] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.
[0062] The present invention provides a method and system for locating faults of an underground audio collection module.
[0063] As attached Figure 1As shown, in a first embodiment of an underground audio acquisition module fault locating method proposed by the present invention, this embodiment is applied to an underground audio acquisition module fault locating system; the system includes a server, and an audio acquisition module disposed in an underground pipeline and communicatively connected to the server; the number of the audio acquisition modules is multiple; the audio acquisition module includes a sound sensor and a buzzer; this embodiment includes the following steps:
[0064] Step S110: the server marks the audio acquisition module closest to the server as the first module.
[0065] Step S120: When all of the audio acquisition modules are working normally, the server controls the buzzers of each audio acquisition module to start in sequence to determine the serial number of each audio acquisition module, wherein the serial number corresponding to each audio acquisition module is unique, the serial number of the first module is 1, and the serial numbers of subsequent audio acquisition modules increase in sequence, and the incremental difference is 1.
[0066] Specifically, the audio acquisition modules corresponding to adjacent serial numbers are closest to each other, that is, the audio acquisition module with serial number 2 is the audio acquisition module closest to the audio acquisition module with serial number 1; the audio acquisition module with serial number 3 is the audio acquisition module closest to the audio acquisition module with serial number 2 (except the audio acquisition module with serial number 1); the audio acquisition module with serial number 4 is the audio acquisition module closest to the audio acquisition module with serial number 3 (except the audio acquisition modules with serial numbers 1 and 2), and so on.
[0067] Step S130: When a fault occurs in the audio acquisition module, the server marks the faulty audio acquisition module as a first target module and obtains the serial number of the first target module.
[0068] Step S140: the server obtains the audio acquisition module corresponding to the serial number that is adjacent to the serial number of the first target module, and marks it as the second target module.
[0069] Step S150: the server obtains the audio acquisition module corresponding to the serial number adjacent to the serial number of the first target module, and marks it as the third target module.
[0070] Step S160: the server determines the position of the first target module based on the positions of the second target module and the third target module.
[0071] Specifically, the audio acquisition module that is closest to the second target module among the audio acquisition modules subsequent to the second target module is the first target module; the audio acquisition module that is closest to the first target module among the audio acquisition modules subsequent to the first target module is the third target module, so the position of the first target module can be determined based on the positions of the second target module and the third target module.
[0072] A method for locating an underground audio acquisition module fault proposed by the present invention can timely and accurately locate an audio acquisition module that has a fault and is installed in an underground pipeline; first, the serial number of each audio acquisition module is determined so that the distance between the audio acquisition modules corresponding to adjacent serial numbers is the shortest; then the audio acquisition module that has a fault is marked as a first target module, and the audio acquisition module corresponding to the serial number adjacent to the serial number before the serial number of the first target module is marked as a second target module, and the audio acquisition module corresponding to the serial number adjacent to the serial number after the serial number of the first target module is marked as a third target module, that is, the second target module and the third target module are the two audio acquisition modules closest to the first target module, and then the positions of the second target module and the third target module are determined, and the position of the first target module is determined based on the positions of the second target module and the third target module.
[0073] In a second embodiment of a method for locating a fault of an underground audio collection module proposed by the present invention, based on the first embodiment, the sound emitted by the buzzer can be transmitted through an underground pipeline, and the sound sensor can collect the sound transmitted through the underground pipeline; step S120 includes the following steps:
[0074] Step S210: the server controls the buzzers of all audio collection modules to be turned off, and controls the sound sensors of all audio collection modules to be turned on, so that each sound sensor sends the collected sound signal to the server.
[0075] Step S220: The server sets i=1.
[0076] Step S230: The server controls the buzzer of the audio acquisition module with serial number i to start, and controls the sound sensor of the audio acquisition module with serial number i to turn off, and then marks the serial number of the audio acquisition module corresponding to the sound sensor corresponding to the sound signal with the highest intensity obtained as i+1.
[0077] Specifically, the intensity of the sound signal collected by the sound sensor of another audio collection module closest to the i-th audio collection module (sent by the buzzer of the i-th audio collection module) must be the largest, so the serial number of the audio collection module corresponding to the sound sensor corresponding to the sound signal with the largest intensity is marked as i+1.
[0078] Step S240: the server controls the buzzer of the audio acquisition module with serial number i to stop.
[0079] Step S250: The server determines whether i+1=M holds, where M is the total number of audio acquisition modules.
[0080] If yes, execute step S260: the server completes determining the serial number of each audio acquisition module.
[0081] If not, execute step S270: the server sets i=i+1, and executes step S230 and subsequent steps.
[0082] Specifically, this embodiment provides a specific solution for determining the sequence number of each audio acquisition module.
[0083] In a third embodiment of a method for locating a fault of an underground audio acquisition module proposed by the present invention, based on the first embodiment, step S160 includes the following steps:
[0084] Step S310: The server determines the distance between any two audio acquisition modules corresponding to two adjacent serial numbers to obtain the distance between the first target module and the second target module, and the distance between the first target module and the third target module.
[0085] Specifically, since the serial numbers corresponding to the first target module and the second target module are two adjacent serial numbers, and the serial numbers corresponding to the first target module and the third target module are two adjacent serial numbers, by determining the distance between two audio acquisition modules corresponding to any two adjacent serial numbers, the distance between the first target module and the second target module, and the distance between the first target module and the third target module can be obtained.
[0086] Step S320: the server controls the buzzers of the second target module and the third target module to start in sequence, respectively, to determine the position of the second target module and the position of the third target module.
[0087] Step S330: the server determines the position of the first target module based on the position of the second target module, the position of the third target module, the distance between the first target module and the second target module, and the distance between the first target module and the third target module.
[0088] Specifically, when the position of the second target module, the position of the third target module, the distance between the first target module and the second target module, and the distance between the first target module and the third target module are known, the position of the first target module can naturally be determined.
[0089] In a fourth embodiment of a method for locating a fault of an underground audio acquisition module proposed by the present invention, based on the third embodiment, step S310 includes the following steps:
[0090] Step S410: the server controls the buzzers and sound sensors of all audio collection modules to be turned off.
[0091] Step S420: The server sets j=1.
[0092] Step S430: The server controls the buzzer of the audio acquisition module with serial number j and the sound sensor of the audio acquisition module with serial number j+1 to start at the same time, and marks the start time as the jth initial time, and then marks the time when the sound sensor of the audio acquisition module with serial number j+1 collects the sound emitted by the buzzer as the jth receiving time.
[0093] Specifically, when the buzzer of the audio acquisition module with serial number j and the sound sensor of the audio acquisition module with serial number j+1 are started at the same time, the sound sensor of the audio acquisition module with serial number j+1 will collect the sound emitted by the buzzer. The collection moment here is the receiving moment. The interval duration between the receiving moment and the initial moment here is determined by the distance between the audio acquisition module with serial number j+1 and the audio acquisition module with serial number j; therefore, the distance between the audio acquisition module with serial number j and the audio acquisition module with serial number j+1 can be determined based on the jth initial moment and the jth receiving moment.
[0094] Step S440: the server determines the distance between the audio acquisition module with a sequence number of j and the audio acquisition module with a sequence number of j+1 based on the j-th initial time and the j-th receiving time.
[0095] Step S450: the server controls the buzzer of the audio acquisition module with the serial number j and the sound sensor of the audio acquisition module with the serial number j+1 to be turned off simultaneously.
[0096] Step S460: The server determines whether j+1=M holds.
[0097] If so, executing step S470: the server completes determining the distance between any two audio acquisition modules corresponding to any two adjacent serial numbers.
[0098] If not, execute step S480: the server sets j=j+1, and executes step S430 and subsequent steps.
[0099] Specifically, this embodiment provides a specific solution for determining the distance between two audio acquisition modules corresponding to any two adjacent serial numbers.
[0100] In a fifth embodiment of a method for locating an underground audio acquisition module fault proposed by the present invention, based on the fourth embodiment, the server determines the distance between the audio acquisition module with sequence number j and the audio acquisition module with sequence number j+1 based on the jth initial moment and the jth receiving moment by the following calculation formula:
[0101] L j =(T j2 -T j1 )×V,
[0102] Where, L j is the distance between the audio acquisition module with serial number j and the audio acquisition module with serial number j+1; T j1 is the jth initial moment, T j2 is the jth receiving moment; V is the propagation speed of sound in the underground pipeline.
[0103] Specifically, in the above formula (T j2 -T j1 ) is the interval between the jth receiving moment and the jth initial moment.
[0104] In a sixth embodiment of a method for locating a fault of an underground audio acquisition module proposed by the present invention, based on the third embodiment, the system further includes a microphone and a monitoring headset; the microphone and the monitoring headset are both communicatively connected to the server; step S320 includes the following steps:
[0105] Step S610: the server controls the buzzer of the second target module to start, and the buzzers of other audio acquisition modules to turn off.
[0106] Step S620: The server obtains the sound signal collected by the microphone when performing mobile detection on the ground where the underground pipeline is located, and marks it as a first target signal, wherein the microphone is held by an operator and moved point by point on the ground near the location of the underground pipeline.
[0107] Step S630: the server sends the first target signal to the monitoring earphone in real time for playback, wherein the monitoring earphone is monitored in real time by an operator.
[0108] Step S640: The operator uses the position of the microphone when the sound intensity of the first target signal is the strongest as the position of the second target module.
[0109] Specifically, the operator holds the microphone and moves point by point on the ground close to the location of the underground pipeline. The intensity of the sound signal collected by the microphone will change continuously, and when the microphone is directly above the second target module, the intensity value of the collected sound signal is the largest, so the position of the second target module can be determined by this.
[0110] In a seventh embodiment of a method for locating a fault of an underground audio acquisition module proposed by the present invention, based on the sixth embodiment, step S640 further includes the following steps:
[0111] Step S710: the server controls the buzzer of the third target module to start, and the buzzers of other audio acquisition modules to turn off.
[0112] Step S720: The server obtains the sound signal collected by the microphone when performing mobile detection on the ground where the underground pipeline is located, and marks it as a second target signal.
[0113] Step S730: the server sends the second target signal to the monitoring headset in real time for playback.
[0114] Step S740: The operator uses the position of the microphone when the sound intensity of the second target signal is the strongest as the position of the third target module.
[0115] Specifically, the operator holds the microphone and moves point by point on the ground close to the location of the underground pipeline. The intensity of the sound signal collected by the microphone will change continuously, and when the microphone is directly above the third target module, the intensity value of the collected sound signal is the largest, so the position of the third target module can be determined.
[0116] In an eighth embodiment of a method for locating a fault of an underground audio acquisition module proposed by the present invention, based on the seventh embodiment, step S330 includes the following steps:
[0117] Step S810: The server obtains a circle with the position of the second target module as the center and the distance between the first target module and the second target module as the radius, and marks it as a first circle.
[0118] Step S820: the server obtains a circle with the position of the third target module as the center and the distance between the first target module and the third target module as the radius, and marks it as a second circle.
[0119] Step S830: The server uses the intersection of the first circle and the second circle as the position of the first target module.
[0120] Specifically, after determining the distance between the first target module and the second target module, and the distance between the first target module and the third target module, the intersection of the first circle and the second circle is the position of the first target module. The operator can dig down at the position of the first target module to find the first target module and repair the first target module.
[0121] In a ninth embodiment of a method for locating a fault of an underground audio acquisition module proposed by the present invention, based on the eighth embodiment, step S830 includes the following steps:
[0122] Step S910: If the number of intersection points between the first circle and the second circle is 2, the server marks the two intersection points as a first suspected location point and a second suspected location point, respectively.
[0123] Specifically, generally speaking, if two circles have an intersection, the number of the intersections is 2, which are respectively the first suspected position point and the second suspected position point in this embodiment, and need to be further identified.
[0124] Step S920: the server obtains the sound signal collected by the microphone at the first suspected position.
[0125] Step S930: the server obtains the sound signal collected by the microphone at the second suspected position.
[0126] Step S940: When the sound intensity of the sound signal collected at the first suspected position point is greater than the sound intensity of the sound signal collected at the second suspected position point, the server uses the first suspected position point as the position point of the first target module.
[0127] Specifically, in the first suspected position point and the second suspected position point, the real first target module is set in the underground water pipe, so the sound signal collected at the position where the real first target module is located will be greater than that of the other non-real position due to the water flow in the underground water pipe.
[0128] Therefore, if the sound intensity of the sound signal collected at the first suspected position point is greater than the sound intensity of the sound signal collected at the second suspected position point, it means that the first suspected position point is the position point of the first target module.
[0129] Step S950: When the sound intensity of the sound signal collected at the first suspected position point is continuously less than the sound intensity of the sound signal collected at the second suspected position point, the server uses the second suspected position point as the position point of the first target module.
[0130] Similarly, if the sound intensity of the sound signal collected at the first suspected position point is greater than the sound intensity of the sound signal collected at the second suspected position point, it means that the first suspected position point is the position point of the first target module.
[0131] The present invention also proposes an underground audio acquisition module fault locating system, which applies an underground audio acquisition module fault locating method; the system includes a server, and an audio acquisition module arranged in an underground pipeline and communicatively connected to the server; the number of the audio acquisition modules is multiple; the audio acquisition module includes a sound sensor and a buzzer.
