目前對於氣體或液體的漏管偵測技術種類繁多，可分為壓力控制法、被動修漏法、定期聽音法、分區計量法及小區測漏法。然而，不論哪一種方式都需要耗費相當長時間檢測，並透過事後的分析才能獲得結果。此外，過於微小的洩漏也難以被檢出，且當洩漏的管道數量較多時，更難以定位出漏管所在位置。 At present, there are many types of leak detection technology for gas or liquid, which can be divided into pressure control method, passive leak repair method, regular listening method, zone measurement method and community leak detection method. However, either method takes a long time to detect, and the results can be obtained through post-mortem analysis.

請參閱圖1，圖1所繪示為本實施例之管道監測系統10。管道監測系統10是適用於一管道8上，管道8主要用於輸送流動的液體或氣體。管道監測系統10包括一第一感測器11S、一第一嵌入設備11、一第二感測器12S、一第二嵌入設備12、一時間同步伺服器13及一GPS衛星14。其中，第一感測器11S是設置於管道8的一第一偵測點8U上，第一感測器11S是用以偵測該第一偵測點8U的狀態值，以產生一第一量測結果。此外，一第二感測器12S是設置於管道8的一第二偵測點8U上，第二偵測點8D位於第一偵測點8U的後端處。具體來說，若以兩者相互 的位置來進行比較，第一偵測點8U位於第二偵測點8D的上游地區，而第二偵測點8D是位於第一偵測點8U位的下游地區。另外，第二感測器12S是用以偵測第二偵測點8D的狀態值，以產生一第二量測結果。上述的第一感測器11S及第二感測器12S例如為水流計、氣流計、水壓計或氣壓計，所以當第一感測器11S及第二感測器12S例如為水流計或氣流計時，第一偵測點8U的狀態值及第二偵測點8D的狀態值為相對應的水流量或氣流量。類似的道理，當第一感測器11S及第二感測器12S例如為水壓計或氣壓計時，第一偵測點8U的狀態值及第二偵測點8D的狀態值便為相對應的水壓值或氣壓值。然而，為有利於本實施例進行說明，下列第一感測器11S及第二感測器12S會以水流計作為主要的範例，所以第一偵測點8U的狀態值及第二偵測點8D的狀態值皆為水流量。因此，該第一量測結果及該第二量測結果的單位為水流量的單位(L/min)。上述中，第一感測器11S加上第一嵌入設備11的組合可被定義為一量測裝置11G。同理，第二感測器12S加上第二嵌入設備12的組合也可視為量測裝置11G。並且，在本領域中，量測裝置11G能在市場上單獨銷售。 Please refer to FIG. 1, which illustrates the pipeline monitoring system 10 of this embodiment. The pipeline monitoring system 10 is suitable for a pipeline 8, and the pipeline 8 is mainly used for conveying flowing liquid or gas. The pipeline monitoring system 10 includes a first sensor 11S, a first embedded device 11, a second sensor 12S, a second embedded device 12, a time synchronization server 13 and a GPS satellite 14. The first sensor 11S is disposed on a first detection point 8U of the pipeline 8, and the first sensor 11S is used to detect the state value of the first detection point 8U to generate a first Measurement results. In addition, a second sensor 12S is disposed on a second detection point 8U of the pipe 8, and the second detection point 8D is located at the rear end of the first detection point 8U. Specifically, if the two For comparison, the first detection point 8U is located upstream of the second detection point 8D, and the second detection point 8D is located downstream of the first detection point 8U. In addition, the second sensor 12S is used to detect the state value of the second detection point 8D to generate a second measurement result. The first sensor 11S and the second sensor 12S described above are, for example, a water flow meter, an air flow meter, a water pressure gauge, or a barometer, so when the first sensor 11S and the second sensor 12S are, for example, a water flow meter or Airflow timing, the state value of the first detection point 8U and the state value of the second detection point 8D correspond to the corresponding water flow or air flow. Similarly, when the first sensor 11S and the second sensor 12S are, for example, water pressure gauges or barometers, the state value of the first detection point 8U and the state value of the second detection point 8D are corresponding The water pressure value or air pressure value. However, to facilitate the description of this embodiment, the following first sensor 11S and second sensor 12S will use a water flow meter as a main example, so the state value of the first detection point 8U and the second detection point The state values of 8D are all water flow. Therefore, the unit of the first measurement result and the second measurement result is the unit of water flow (L/min). In the above, the combination of the first sensor 11S and the first embedded device 11 can be defined as a measurement device 11G. Similarly, the combination of the second sensor 12S and the second embedding device 12 can also be regarded as the measuring device 11G. Also, in the field, the measuring device 11G can be sold separately on the market.

此外，該第二量測結果是對應於第一量測結果，上述兩結果「對應」的定義詳細來說如下：當管道8的一部份水流抵達第一偵測點8U時，第一感測器11S會偵測出該部份水流當下的流速，因而產生第一量測結果。之後，當該部份水流抵達第二偵測點8D時，第二感測器12S會偵測出該部份水流當下的流速，以產生第二量測結果。並且，由於該第一量測結果及該第二量測結果皆由該部份水流(同一瞬間的水流)有關聯，所以第二量測結果與第一量測結果屬於對應關係。此外，在沒有能量損耗的情況下，第一量測結果會相同於第二量測結果，也就是兩者的水流量會相同(流速相同)。然而，由於該部份水流經過管道8時會產生能量的損失(例如受到管壁的摩擦力或其他因數所影響)，所以在實際測量的狀態下，第二量測結果會略小於第一量測結果，也就是第二偵測點8D的水流量會略 小於第一偵測點8U。當然，兩者水流量的差距會與管道8的管長、管徑及材質息息相關。 In addition, the second measurement result corresponds to the first measurement result. The definition of the "correspondence" of the above two results is as follows: when a part of the water flow of the pipe 8 reaches the first detection point 8U, the first sense The measuring device 11S will detect the current flow velocity of the partial water flow, thus generating a first measurement result. After that, when the partial water flow reaches the second detection point 8D, the second sensor 12S will detect the current flow speed of the partial water flow to generate a second measurement result. Moreover, since both the first measurement result and the second measurement result are related by the partial water flow (water flow at the same instant), the second measurement result and the first measurement result belong to a corresponding relationship. In addition, in the case of no energy loss, the first measurement result will be the same as the second measurement result, that is, the water flow rate of the two will be the same (the same flow rate). However, due to the loss of energy when the part of the water flows through the pipe 8 (for example, due to the friction of the pipe wall or other factors), in the actual measurement state, the second measurement result will be slightly less than the first amount The measurement result, that is, the water flow at the second detection point 8D will be slightly 8U less than the first detection point. Of course, the difference in water flow between the two will be closely related to the length, diameter and material of the pipe 8.

另外，請再參閱圖1，第一嵌入設備11是用以接收該第一量測結果，且第一嵌入設備11會依據接收到該第一量測結果的時間形成一第一時間戳記。換句話說，產生該第一量測結果當下的時間也會一同被記錄於本系統中。此外，第二嵌入設備12是用以接收該第二量測結果，且第二嵌入設備12也會依據接收到該第二量測結果的時間形成一第二時間戳記。換句話說，產生該第二量測結果當下的時間也會一同被記錄於本系統中。並且，經由第一時間戳記及第二時間戳記之間的時間差異(當得知該第一量測結果的流速與上下游偵測點的距離，便能計算出該部分水流抵達至第二偵測點8D所需花費的時間)，更能確認該第一量測結果與該第二量測結果是否為對應關係。另外，GPS衛星14是以PTP協定(精密時間協議)同步時間同步伺服器13、第一嵌入設備11及第二嵌入設備12的時間。具體來說，GPS衛星透過高精度時間同步協定(PTP)校正時間同步伺服器13的時間，並將時間同步伺服器13設為主時鐘(Master clock)，而第一嵌入設備11及第二嵌入設備12設定為從時鐘(Slaver clock)，並利用高精度時間同步協定(PTP)使第一嵌入設備11及第二嵌入設備12的時間同步於時間同步伺服器13。上述中，利用PTP協定也能讓第一嵌入設備11設定為主時鐘(Master clock)，第二嵌入設備12設定為從時鐘(Slaver clock)，所以第二嵌入設備12也能單獨同步第一嵌入設備11的時間。反之，當第二嵌入設備12設定為主時鐘(Master clock)，而第一嵌入設備11設定為從時鐘(Slaver clock)時，第一嵌入設備11便能單獨同步第二嵌入設備12的時間。另外，在其他的應用上，也能將第一嵌入設備11設定為主時鐘(Master clock)，時間同步伺服器13設定為從時鐘(Slaver clock)，所以第一嵌入設備11便能同步時間同步伺服器13的時間。此外，除了使用高精度時間同步協定(PTP)來同步各項設備的時間之外，本領域通常知識者也能透過網路時間同步協定 (Network Time Protocol，簡稱NTP)同步各項設備的時間，舉例來說：第一嵌入設備11能以NTP協定同步第二嵌入設備12的時間或第二嵌入設備12以NTP協定同步第一嵌入設備11的時間。或者，第一嵌入設備11以NTP協定同步時間同步伺服器13的時間。 In addition, please refer to FIG. 1 again, the first embedding device 11 is used to receive the first measurement result, and the first embedding device 11 forms a first time stamp according to the time when the first measurement result is received. In other words, the current time when the first measurement result is generated will also be recorded in the system. In addition, the second embedded device 12 is used to receive the second measurement result, and the second embedded device 12 also forms a second time stamp according to the time when the second measurement result is received. In other words, the current time when the second measurement result is generated will also be recorded in the system. And, through the time difference between the first timestamp and the second timestamp (when the distance between the flow rate of the first measurement result and the upstream and downstream detection points is known, it can be calculated that the part of the water flow reaches the second detection (The time it takes for the measuring point 8D), and it can confirm whether the first measurement result and the second measurement result are in a corresponding relationship. In addition, the GPS satellite 14 synchronizes the time of the time synchronization server 13, the first embedded device 11, and the second embedded device 12 with the PTP protocol (Precision Time Protocol). Specifically, the GPS satellite corrects the time of the time synchronization server 13 through a high-precision time synchronization protocol (PTP), and sets the time synchronization server 13 as a master clock, and the first embedded device 11 and the second embedded The device 12 is set as a slave clock, and uses the high precision time synchronization protocol (PTP) to synchronize the time of the first embedded device 11 and the second embedded device 12 with the time synchronization server 13. In the above, using the PTP protocol can also make the first embedded device 11 set as the master clock and the second embedded device 12 set as the slave clock, so the second embedded device 12 can also synchronize the first embedded separately Device 11 time. Conversely, when the second embedding device 12 is set as a master clock and the first embedding device 11 is set as a slave clock, the first embedding device 11 can synchronize the time of the second embedding device 12 alone. In addition, in other applications, the first embedded device 11 can also be set as the master clock (Master clock), and the time synchronization server 13 can be set as the slave clock (Slaver clock), so the first embedded device 11 can synchronize time synchronization Server 13 time. In addition, in addition to using high-precision time synchronization protocol (PTP) to synchronize the time of various devices, those skilled in the art can also use network time synchronization protocol (Network Time Protocol, NTP for short) synchronizes the time of each device, for example: the first embedded device 11 can synchronize the time of the second embedded device 12 with the NTP protocol or the second embedded device 12 synchronizes the first embedded device with the NTP protocol 11 hours. Alternatively, the first embedded device 11 synchronizes the time of the time synchronization server 13 with the NTP protocol.

上述中，該第一量測結果、該第一時間戳記、該第二量測結果及該第二時間戳記皆會被傳送至時間同步伺服器13。其中，時間同步伺服器13會將該第一量測結果及第二量測結果進行比對，以產生一差異值。接著，當該差異值大於一流量誤差值時，時間同步伺服器13會立即發出一警告訊息。首先，以第一例子舉例如下：當流量誤差值被設定為2L/min，該第一量測結果為10L/min，該第二量測結果為9.5L/min時，其差異值為0.5L/min(0.5L/min的水流量差異屬於水流運送時的能量損耗)。由於差異值0.5L/min沒有超出流量誤差值2L/min，所以時間同步伺服器13不會發出該警告訊息。再者，以第二例子舉例如下：當流量誤差值同樣設定為2L/min，該第一量測結果為10L/min，該第二量測結果為7.6L/min時，其差異值為2.4L/min。由於第二例子的差異值2.4L/min已超出流量誤差值2L/min，所以時間同步伺服器13會發出該警告訊息。這也是因為差異值2.4L/min已屬於異常的流量差異，所以經由管道監測系統10便能得知在第一偵測點8U及第二偵測點8D之間已有管道洩漏的情況發生。因此，相較於傳統的漏管偵測技術，本實施例之管道監測系統10能即時偵測到漏管所在位置，也就是將漏管的範圍縮小至第一偵測點8U及第二偵測點8D之間。此外，由於本實施例可依據管道8所會產生的能量損失去設定該流量誤差值的大小，所以縱使是微小的管道洩漏(只要超出該流量誤差值)，還是會被管道監測系統10所察覺出。 In the above, the first measurement result, the first time stamp, the second measurement result, and the second time stamp are all sent to the time synchronization server 13. The time synchronization server 13 compares the first measurement result with the second measurement result to generate a difference value. Then, when the difference value is greater than a flow error value, the time synchronization server 13 will immediately issue a warning message. First, take the first example as follows: When the flow error value is set to 2L/min, the first measurement result is 10L/min, and the second measurement result is 9.5L/min, the difference is 0.5L /min (0.5L/min water flow difference belongs to energy loss during water flow). Since the difference value 0.5L/min does not exceed the flow error value 2L/min, the time synchronization server 13 will not issue this warning message. Furthermore, taking the second example as an example: when the flow error value is also set to 2L/min, the first measurement result is 10L/min, and when the second measurement result is 7.6L/min, the difference value is 2.4 L/min. Since the difference value of 2.4 L/min in the second example has exceeded the flow error value of 2 L/min, the time synchronization server 13 will issue the warning message. This is also because the difference of 2.4L/min is already an abnormal flow difference, so the pipeline monitoring system 10 can be informed that there is a pipeline leakage between the first detection point 8U and the second detection point 8D. Therefore, compared to the conventional leak detection technology, the pipeline monitoring system 10 of this embodiment can detect the location of the leak in real time, that is, the scope of the leak is reduced to the first detection point 8U and the second detection Between measuring points 8D. In addition, since this embodiment can set the size of the flow error value according to the energy loss generated by the pipeline 8, even if it is a small pipeline leakage (as long as the flow error value is exceeded), it will still be noticed by the pipeline monitoring system 10 Out.

另外，上述中，若第一嵌入設備11的時間沒有同步於第二嵌入設備12的時間，該第一量測結果、該第二量測結果及該差異值就可能是錯誤的數值參數， 不具參考性。因此，本實施例利用PTP協定(精密時間協議)讓各個設備的時間同步便能確保第一量測結果、該第二量測結果及該差異值的準確性。 In addition, in the above, if the time of the first embedded device 11 is not synchronized with the time of the second embedded device 12, the first measurement result, the second measurement result, and the difference value may be wrong numerical parameters, Not informative. Therefore, this embodiment uses the PTP protocol (Precision Time Protocol) to synchronize the time of each device to ensure the accuracy of the first measurement result, the second measurement result, and the difference value.

請參閱圖2，圖2所繪示為另一實施例之管道監測系統20。管道監測系統20與管道監測系統10的差異在於：管道監測系統20還包括一監測設備25，監測設備25例如為桌上型電腦、筆記型電腦、平板電腦或智慧型手機。其中，監測設備25是從時間同步伺服器13接收該第一量測結果、該第二量測結果及該警告訊息。這樣一來，監測設備25的使用者便能得知管道8是否有洩漏的情況發生，還能得知管道8內的水流量是否正常。 Please refer to FIG. 2, which illustrates a pipeline monitoring system 20 according to another embodiment. The difference between the pipeline monitoring system 20 and the pipeline monitoring system 10 is that the pipeline monitoring system 20 further includes a monitoring device 25, such as a desktop computer, a notebook computer, a tablet computer or a smart phone. The monitoring device 25 receives the first measurement result, the second measurement result, and the warning message from the time synchronization server 13. In this way, the user of the monitoring device 25 can know whether the pipeline 8 is leaking, and can also know whether the water flow in the pipeline 8 is normal.

請參閱圖3，圖3所繪示為再一實施例之管道監測系統30。管道監測系統30與管道監測系統10的差異在於：管道監測系統30具有二個第二感測器12S及二個第二嵌入設備12(管道監測系統10只有一個第二感測器12S及一個第二嵌入設備12)。因此，管道監測系統30便可應用於分岔的管道81上，也就是外觀為「Y」字型的管道81。並且，類似管道監測系統10的運作方式，管道監測系統30同樣能即時偵測到管道81的漏管所在位置。 Please refer to FIG. 3. FIG. 3 illustrates a pipeline monitoring system 30 according to yet another embodiment. The difference between the pipeline monitoring system 30 and the pipeline monitoring system 10 is that the pipeline monitoring system 30 has two second sensors 12S and two second embedded devices 12 (the pipeline monitoring system 10 has only one second sensor 12S and one first Two embedded devices 12). Therefore, the pipeline monitoring system 30 can be applied to the branched pipeline 81, that is, the pipeline 81 having a "Y" appearance. Moreover, similar to the operation of the pipeline monitoring system 10, the pipeline monitoring system 30 can also instantly detect the location of the leaky pipe of the pipe 81.

請參閱圖4，圖4所繪示為又一實施例之管道監測系統40。管道監測系統40與管道監測系統10的差異在於：管道監測系統4具有二個第一感測器11S及二個第一嵌入設備11、二個第二感測器12S及二個第二嵌入設備12(管道監測系統10只有一第一感測器11S及一個第一嵌入設備11、一個第二感測器12S及一個第二嵌入設備12)。因此，管道監測系統40便可應用於外觀為「X」字型的管道82。並且，相同於管道監測系統10的運作方式，本實施例之管道監測系統40同樣能即時偵測到管道82的漏管所在位置。 Please refer to FIG. 4, which illustrates a pipeline monitoring system 40 according to another embodiment. The difference between the pipeline monitoring system 40 and the pipeline monitoring system 10 is that the pipeline monitoring system 4 has two first sensors 11S and two first embedding devices 11, two second sensors 12S and two second embedding devices 12 (the pipeline monitoring system 10 has only a first sensor 11S and a first embedded device 11, a second sensor 12S and a second embedded device 12). Therefore, the pipeline monitoring system 40 can be applied to the pipeline 82 having an "X" appearance. Moreover, in the same way as the operation mode of the pipeline monitoring system 10, the pipeline monitoring system 40 of this embodiment can also instantly detect the location of the leaky pipe of the pipeline 82.
