[0029] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.
[0030] At present, the detection of thermal pipeline leakage in the integrated pipeline corridor mainly monitors a single environmental parameter. Generally, the changes in environmental parameters such as ambient pressure, ambient temperature or humidity in the water thermal chamber in the integrated pipeline corridor are monitored to determine whether the thermal pipeline is leaking.
[0031] In reality, environmental parameters in the hydrothermal chamber within the integrated pipe corridor will only change after pipeline leakage reaches a certain level. Therefore, existing monitoring methods cannot provide rapid warnings when thermal pipelines leak, potentially exacerbating the losses caused by leaks.
[0032] In order to solve the above problems, an embodiment of the present invention provides an alarm device for thermal pipe leakage in a comprehensive pipe gallery, which is used to quickly issue an alarm message when a thermal pipe leaks, such as Figure 1 As shown, the alarm device for thermal pipeline leakage in the integrated pipe gallery may include:
[0033] Vibration cable sensor 01 is used to monitor in real time whether there are any vibration points in the thermal pipeline; obtain the vibration parameters and position of the vibration points, generate vibration signals, and convert the vibration signals into electrical signals; the vibration parameters include vibration intensity and vibration frequency;
[0034] The signal processor 02 is used to analyze the electrical signal and determine the number of vibration points in the thermal pipeline;
[0035] If the number of vibration points is single, determining whether the vibration parameter value of the single vibration point exceeds a preset value;
[0036] When it is determined that the vibration parameter value of the single vibration point exceeds the preset value, an alarm message is issued indicating that a leak has occurred at the vibration point in the thermal pipeline in the integrated pipe gallery;
[0037] If there are multiple vibration points, determine whether the distances between adjacent vibration points in the multiple vibration points are the same, and whether the vibration parameter value of each vibration point exceeds a preset value;
[0038] When it is determined that the distances between adjacent vibration points among the multiple vibration points are different, for each vibration point among the multiple vibration points whose vibration parameter value exceeds a preset value, an alarm information is issued indicating that a leak has occurred at the position of the vibration point in the thermal pipeline in the integrated pipeline corridor.
[0039] In the embodiment of the present invention, the vibration cable sensor is used to monitor in real time whether there are vibration points in the thermal pipeline; obtain the vibration parameters and position of the vibration point, generate a vibration signal, and convert the vibration signal into an electrical signal; the vibration parameters include vibration intensity and vibration frequency; the signal processor is used to analyze the electrical signal and determine the number of vibration points in the thermal pipeline; if the number of vibration points is single, determine whether the vibration parameter value of the single vibration point exceeds a preset value; when it is determined that the vibration parameter value of the single vibration point exceeds the preset value, issue an alarm message of leakage at the position of the vibration point in the thermal pipeline in the integrated pipe gallery; if the number of vibration points is multiple, determine whether the multiple vibration points are multiple. Whether the distances between adjacent vibration points are the same, and whether the vibration parameter value of each vibration point exceeds a preset value; when it is determined that the distances between adjacent vibration points among the multiple vibration points are different, for each vibration point among the multiple vibration points whose vibration parameter value exceeds the preset value, an alarm information of leakage occurring at the position of the vibration point in the thermal pipeline in the integrated pipeline corridor is issued, thereby realizing a rapid alarm of leakage in the thermal pipeline by monitoring the vibration points in the thermal pipeline. Compared with the existing technology, it avoids the situation where the alarm information can only be issued after the leakage of the thermal pipeline reaches a certain level; at the same time, the location of the leakage in the thermal pipeline can be determined in time, saving time and reducing the loss caused by pipeline leakage.
[0040] In specific implementation, the vibration cable sensor can be used to monitor in real time whether there are vibration points in the thermal pipeline; obtain the vibration parameters and position of the vibration point, generate a vibration signal, and convert the vibration signal into an electrical signal; the vibration parameters include vibration intensity and vibration frequency.
[0041] In one embodiment, the vibration cable sensor can be used to monitor the vibration of the thermal pipeline, convert the vibration signal into an electrical signal, and transmit the electrical signal to the front-end signal processor. The vibration of the thermal pipeline may include vibration caused by a small leak in the thermal pipeline or gas leakage.
[0042] In one embodiment, a vibration cable sensor may include an electromagnetic induction vibration cable detector, also known as a vibration cable. A vibration cable consists of a core wire, a pressure-sensitive film, a shielding layer, and a jacket. It is primarily used in the perimeter security industry. It can be installed in various ironwork, fences, netting, or even embedded in walls. It can be used in conjunction with switch-output cable vibration output devices, single-cable cable vibration alarm devices, or network-type cable vibration alarm devices to detect and alarm for trespassing and intrusion. The vibration cable sensor in this embodiment of the present invention can be configured with a self-identification function. When the vibration cable sensor detects that the pipeline it is installed in is vibrating for some reason, it not only detects the vibration but also scans a preset length around the vibration point to see if there are other vibration points nearby. If a new vibration point is detected within the preset length, the vibration cable sensor not only identifies it but also quickly transmits this information to the front-end signal processor. The preset length can be set by the operator based on the actual performance of the vibration cable sensor.
[0043] In the above embodiment, by setting up a vibration cable sensor, the vibration condition of the thermal pipeline can be monitored in real time, which can be used to determine whether there is a vibration point in the thermal pipeline where vibration occurs; and the vibration parameters of the vibration point can be obtained to generate a vibration signal; the above vibration parameters include the vibration point position, vibration intensity and vibration frequency; the vibration signal is converted into an electrical signal, thereby achieving the purpose of real-time monitoring of the thermal pipeline.
[0044] In a specific implementation, the signal processor can be used to analyze the electrical signal to determine the number of vibration points in the thermal pipeline;
[0045] If the number of vibration points is single, determining whether the vibration parameter value of the single vibration point exceeds a preset value;
[0046] When it is determined that the vibration parameter value of the single vibration point exceeds the preset value, an alarm message is issued indicating that a leak has occurred at the vibration point in the thermal pipeline in the integrated pipe gallery;
[0047] If there are multiple vibration points, determine whether the distances between adjacent vibration points in the multiple vibration points are the same, and whether the vibration parameter value of each vibration point exceeds a preset value;
[0048] When it is determined that the distances between adjacent vibration points among the multiple vibration points are different, for each vibration point among the multiple vibration points whose vibration parameter value exceeds a preset value, an alarm information is issued indicating that a leak has occurred at the position of the vibration point in the thermal pipeline in the integrated pipeline corridor.
[0049] In the embodiment, the signal processor may be used to receive the electrical signal from the vibration cable sensor and perform analysis and calculation based on the electrical signal sent by the sensor.
[0050] In one embodiment, the signal processor may be a front-end signal processor that can determine the nature of the vibration based on the electrical signal sent by the cable sensor.
[0051] In one embodiment, the signal processor is a processor that can also be used to send a vibration detection pulse signal to the vibration cable sensor. The vibration detection pulse signal can be used to control the vibration cable sensor to monitor the thermal pipeline, thereby assisting the staff to monitor the vibration conditions of the thermal pipeline.
[0052] In the above embodiment, the signal processor can analyze the electrical signal to determine the number of vibration points in the thermal pipeline. When it is determined that the number of vibration points is single, it is determined whether the vibration intensity and vibration frequency of the single vibration point exceed the preset values. When it is determined that the vibration intensity and vibration frequency of the single vibration point exceed the preset values, an alarm message is issued indicating that a leak has occurred at the location of the single vibration point in the thermal pipeline in the integrated pipe gallery.
[0053] When it is determined that there are multiple vibration points, it is judged whether the distances between adjacent vibration points in the multiple vibration points are the same, and whether the vibration intensity and vibration frequency of the multiple vibration points exceed the preset values; when it is judged that the distances between adjacent vibration points in the multiple vibration points are not the same, and the vibration intensity and vibration frequency of the multiple vibration points exceed the preset values, an alarm information is issued that leakage has occurred at the positions of the multiple vibration points in the thermal pipelines in the integrated pipeline corridor, thereby achieving the purpose of quickly issuing an alarm for leakage in the thermal pipelines by monitoring the vibration points in the thermal pipelines.
[0054] In the above embodiment, the signal processor can analyze the electrical signal and, when there are multiple vibration points in the thermal pipeline, determine whether the spacing between adjacent vibration points is the same, and whether the vibration intensity and vibration frequency of the multiple vibration points exceed preset values.
[0055] When it is determined that the distances between adjacent vibration points among the multiple vibration points are different, and the vibration intensity and vibration frequency of the multiple vibration points exceed the preset values, an alarm message is issued that leakage has occurred at the multiple vibration points in the thermal pipelines in the integrated pipeline corridor, thereby enabling a rapid alarm of leakage in the thermal pipelines by monitoring the vibration points in the thermal pipelines.
[0056] In a specific implementation, the signal processor can also be used to: when monitoring and detecting the presence of a single vibration point in the thermal pipeline, scan whether there are multiple vibration points in the thermal pipeline within a preset range centered on the single vibration point; if there are multiple vibration points in the thermal pipeline, cyclically scan whether there are other vibration points in the thermal pipeline within a preset range centered on each of the multiple vibration points; repeat the above steps until all vibration points in the thermal pipeline are scanned.
[0057] In a specific implementation, the signal processor can also be used to: when monitoring and finding that there are multiple vibration points in the thermal pipeline, scan whether there are multiple vibration points in the thermal pipeline within a preset range centered on each of the multiple vibration points; if there are multiple vibration points in the thermal pipeline, cyclically scan whether there are other vibration points in the thermal pipeline within a preset range centered on each of the multiple vibration points; repeat the above steps until all vibration points in the thermal pipeline are scanned.
[0058] In the above embodiment, when the vibration cable sensor detects the presence of a vibration point in the thermal pipeline during monitoring, it then scans whether there are multiple vibration points in the thermal pipeline within a preset range centered on the vibration point; it cyclically scans whether there are other vibration points in the thermal pipeline within the preset range centered on each vibration point; and repeats the above steps until all the vibration points in the thermal pipeline are scanned. All the vibration points in the thermal pipeline can be scanned, which helps to better realize the alarm of thermal pipeline leakage in the integrated pipeline corridor and improves the accuracy of judging the leakage location of the thermal pipeline in the integrated pipeline corridor.
[0059] In one embodiment, the preset range can be 8.8 meters, which can be set by the operator based on usage requirements. In this embodiment, the vibration cable sensor can not only detect the vibration of the thermal pipe, but also scan 8.8 meters to the left and right of the vibration point to determine whether there are other vibration points nearby. If a new vibration point is found within 8.8 meters, the vibration cable sensor can identify it and quickly send this information to the front-end signal processor.
[0060] In a specific implementation, the signal processor may also be used to: determine that no leakage occurs in the thermal pipeline when it is determined that either the vibration intensity or the vibration frequency of the single vibration point does not exceed a preset value.
[0061] In one embodiment, if neither the vibration intensity nor the vibration frequency at the single vibration point exceeds a preset value, the signal processor may determine that the thermal pipeline is vibrating due to unexpected interference caused by environmental factors, rather than a leak in the thermal pipeline. Unexpected interference may include ground vibrations and vibrations caused by vehicles passing through the ground above the thermal pipeline.
[0062] In a specific implementation, the vibration cable sensor can also be used to: when it is determined that the distances between adjacent vibration points in the multiple vibration points are the same, determine that no leakage occurs in the thermal pipeline.
[0063] In specific implementation, the vibration cable sensor can also be used to: when it is determined that the distances between adjacent vibration points among the multiple vibration points are different, and none of the vibration intensity and vibration frequency of the multiple vibration points exceeds the preset value, issue an alarm message that a leak has occurred at the multiple vibration point positions in the thermal pipeline in the integrated pipeline corridor where the vibration intensity and vibration frequency exceed the preset value.
[0064] In the embodiment, after analyzing the electrical signal, if there are multiple vibration points, it can be determined whether the intervals between adjacent vibration points in the multiple vibration points are the same;
[0065] If the distances between adjacent vibration points in the multiple vibration points are the same, it is determined that there is no leakage in the thermal pipeline;
[0066] If the distances between adjacent vibration points in multiple vibration points are different, it is determined whether the vibration intensity and vibration frequency of each vibration point exceed the preset values; when the vibration intensity and vibration frequency of each vibration point exceed the preset values, an alarm message is issued indicating that leakage has occurred at the multiple vibration points in the thermal pipelines in the integrated pipeline corridor.
[0067] In the above embodiment, the signal processor can analyze the electrical signal to determine whether the distances between adjacent vibration points among the multiple vibration points are the same; if the distances between adjacent vibration points among the multiple vibration points are the same, it is determined that no leakage has occurred in the thermal pipeline, and it can be determined that the vibration of the thermal pipeline is due to unexpected interference.
[0068] If the distances between adjacent vibration points in multiple vibration points are different, it is determined whether the vibration intensity and vibration frequency of each vibration point exceed the preset values; when the vibration intensity and vibration frequency of each vibration point exceed the preset values, an alarm message is issued indicating that leakage has occurred at the multiple vibration points in the thermal pipelines in the integrated pipeline corridor.
[0069] The signal processor can analyze the vibration intensity and vibration frequency of each vibration point. When the vibration intensity and vibration frequency of different vibration points exceed preset values, it can be determined that leakage occurs at all the vibration points of the above-mentioned thermal pipeline.
[0070] In one embodiment, the signal processor can analyze the electrical signal to determine whether the spacing between adjacent vibration points among multiple vibration points is the same; if the spacing between adjacent vibration points among multiple vibration points is not the same, determine whether the vibration intensity and vibration frequency of each vibration point exceed the preset value; if the vibration intensity and vibration frequency of one or more vibration points among multiple vibration points exceed the preset value, it can be determined that a leak has occurred at the one or more vibration points, and an alarm information is issued that a leak has occurred at the one or more vibration points in the thermal pipeline in the integrated pipeline corridor.
[0071] In the above embodiment, when the vibration cable sensor detects vibrations at many consecutive points along the pipeline, the front-end signal processor may determine that this is vibration caused by factors such as the operation of the pipeline itself and will not process it; if the received information shows that there is vibration only at isolated locations on the pipeline, the front-end signal processor will further test the number of vibrations and the vibration intensity per unit time. If the set standards are not met, the processor may determine that this is a transient interference and will not process it; only when the processor detects that the location distribution of the vibration, the number of vibrations and the vibration intensity all meet the set standards, will it determine that this is a real leakage vibration and calculate the exact location of the alarm (with an accuracy of 3 meters), thereby sending all the information of the alarm event to the control center.
[0072] In specific implementation, the signal processor can also be used to:
[0073] When implementing it specifically, Figure 2 As shown, an alarm device for thermal pipeline leakage in an integrated pipe gallery provided by an embodiment of the present invention may also include a power supply 03 for powering the vibration cable sensor and the signal processor.
[0074] In the above embodiment, a power supply is provided to supply power to the vibration cable sensor and the signal processor, thereby ensuring the normal operation of the vibration cable sensor and the signal processor. The power supply may be a DC 48V power supply.
[0075] In one embodiment, an alarm device for thermal pipeline leakage in an integrated pipe gallery provided by an embodiment of the present invention may further include: a first communication interface for transmitting signals between a vibration cable sensor and a signal processor.
[0076] In one embodiment, in an alarm device for leakage of a thermal pipeline in an integrated pipeline corridor provided by an embodiment of the present invention, the signal processor may include a second communication interface for issuing an alarm message indicating leakage at the single vibration point in the thermal pipeline in the integrated pipeline corridor.
[0077] A specific embodiment is given below to illustrate the specific application of the method of the present invention. Figure 3 As shown, this embodiment may include a terminal unit and a signal unit (i.e., a signal processor, which is arranged in the terminal unit, and the terminal unit can be loaded with a signal processor and set according to usage requirements), a communication interface, DC48v (i.e., a DC 48v power supply) and a vibration cable (i.e., a vibration cable sensor).
[0078] The vibration cable's primary function is to monitor the vibration of the thermal pipeline, converting the vibration signal into an electrical signal and transmitting it to the front-end signal processor. A key feature of this vibration cable is its self-identification capability. When the pipeline vibrates for some reason, the cable not only detects the vibration but also scans an 8.8-meter radius around the vibration point to determine if there are other vibrating points nearby. If a new vibration point appears within the 8.8-meter radius, the cable not only identifies it but also quickly transmits this information to the front-end signal processor. The cable then repeats the scanning process again, scanning an 8.8-meter radius around the new vibration point. Therefore, the vibration cable sensor not only detects pipeline vibration signals but also determines whether the vibration is occurring at a single point or across multiple locations along the pipeline. This intelligent cable enables the signal processor to determine whether the vibration is a single point caused by a true warning event or distributed vibration due to environmental factors.
[0079] The signal unit is a signal processor whose primary function is to send vibration detection pulse signals to the vibration cable, receive electrical signals from the vibration cable, and perform analysis and calculations based on the information transmitted by the vibration cable. The signal unit can determine the nature of the vibration based on the information transmitted by the vibration cable. If the vibration cable detects vibration at multiple consecutive points along the pipeline, the signal unit may determine that the vibration is caused by factors such as pipeline operation and not process it. If the received information indicates that the vibration is only at isolated locations, the signal unit will further test the number of vibrations per unit time and the intensity. If these do not meet the specified standards, the signal unit may determine that the vibration is transient and not process it. Only when the vibration distribution, number of vibrations (i.e., frequency), and intensity all meet the specified standards will the signal unit determine that the vibration is a true leak and calculate the precise location of the alarm (with an accuracy of 3 meters), thereby transmitting all the alarm information to the control center. If the vibration cable detects vibration at multiple points along the pipeline, and the vibration location analyzed by the signal unit is uneven, the vibration can be determined to be not caused by environmental factors. The signal unit can further test the number of vibrations and vibration intensity per unit time. When the set standards are met, it will simultaneously determine that these points are real leakage points, and calculate the precise location of the alarm, thereby sending all the information of the alarm to the control center.
[0080] In the embodiment of the present invention, the vibration cable sensor is used to monitor in real time whether there are vibration points in the thermal pipeline; obtain the vibration parameters and position of the vibration point, generate a vibration signal, and convert the vibration signal into an electrical signal; the vibration parameters include vibration intensity and vibration frequency; the signal processor is used to analyze the electrical signal and determine the number of vibration points in the thermal pipeline; if the number of vibration points is single, determine whether the vibration parameter value of the single vibration point exceeds a preset value; when it is determined that the vibration parameter value of the single vibration point exceeds the preset value, issue an alarm message of leakage at the position of the vibration point in the thermal pipeline in the integrated pipe gallery; if the number of vibration points is multiple, determine whether the multiple vibration points are multiple. Whether the distances between adjacent vibration points are the same, and whether the vibration parameter value of each vibration point exceeds a preset value; when it is determined that the distances between adjacent vibration points among the multiple vibration points are different, for each vibration point among the multiple vibration points whose vibration parameter value exceeds the preset value, an alarm information of leakage occurring at the position of the vibration point in the thermal pipeline in the integrated pipeline corridor is issued, thereby realizing a rapid alarm of leakage in the thermal pipeline by monitoring the vibration points in the thermal pipeline. Compared with the existing technology, it avoids the situation where the alarm information can only be issued after the leakage of the thermal pipeline reaches a certain level; at the same time, the location of the leakage in the thermal pipeline can be determined in time, saving time and reducing the loss caused by pipeline leakage.
[0081] In this embodiment of the present invention, a vibration cable sensor can be installed on a thermal pipeline. Based on the pipeline's vibration changes, it can determine whether the pipeline is leaking, thereby providing an early warning of leaks and displaying the leak's location with an accuracy of approximately 3 meters. This allows for timely identification of leaks, saving time and enabling workers to promptly repair the leak, thereby mitigating losses caused by the pipeline leak.
[0082] The embodiment of the present invention also provides an alarm method for thermal pipeline leakage in an integrated pipe gallery, which can be applied to the above-mentioned thermal pipeline leakage alarm device in the integrated pipe gallery to quickly issue an alarm message when a thermal pipeline leaks, such as Figure 4 As shown, the method includes:
[0083] Step 401: The vibration cable sensor monitors in real time whether there is a vibration point in the thermal pipeline; obtains vibration parameters and positions of the vibration points, generates a vibration signal, and converts the vibration signal into an electrical signal; the vibration parameters include vibration intensity and vibration frequency;
[0084] Step 402: The signal processor analyzes the electrical signal to determine the number of vibration points in the thermal pipeline;
[0085] If the number of vibration points is single, determining whether the vibration parameter value of the single vibration point exceeds a preset value;
[0086] When it is determined that the vibration parameter value of the single vibration point exceeds the preset value, an alarm message is issued indicating that a leak has occurred at the vibration point in the thermal pipeline in the integrated pipe gallery;
[0087] If there are multiple vibration points, determine whether the distances between adjacent vibration points in the multiple vibration points are the same, and whether the vibration parameter value of each vibration point exceeds a preset value;
[0088] When it is determined that the distances between adjacent vibration points among the multiple vibration points are different, for each vibration point among the multiple vibration points whose vibration parameter value exceeds a preset value, an alarm information is issued indicating that a leak has occurred at the position of the vibration point in the thermal pipeline in the integrated pipeline corridor.
[0089] In one embodiment, the present invention provides an alarm method for thermal pipeline leakage in an integrated pipe gallery, such as Figure 5 As shown, it may also include:
[0090] Step 501: When the vibration cable sensor detects at least one vibration point in the thermal pipeline, it scans the thermal pipeline for other vibration points within a preset range with the vibration point as the center.
[0091] Step 502: For each vibration point scanned, continue to scan the thermal pipeline within a preset range with the vibration point as the center to see if there are other vibration points. Repeat the above steps until no new vibration points are found.
[0092] In one embodiment, the method for alarming leakage of a thermal pipeline in an integrated pipe gallery provided by the embodiment of the present invention may further include:
