[0082] According to the gas leakage locating method provided by the present invention, the detection mechanism 3 is set at both ends of the gas pipeline 1, and the gas flow rate inside each gas pipeline 1 can be better determined when observing the gas flow rate in step three.

[0083] The gas leakage locating method provided in the embodiment of the present invention installs the detection mechanism 3 together with the connecting piece 2 at both ends of the gas pipeline 1, so that when the gas flow rate detection and observation is performed in step three, the change of the gas flow rate inside each gas pipeline 1 can be better determined, so that when locating the leakage, it can be located on each specific gas pipeline 1, thereby making the positioning more accurate. Through accurate positioning, it is more convenient to confirm the position when repairing the leaking pipeline, thereby improving the overall maintenance work efficiency and reducing the workload of maintenance workers.

[0084] Method of use of the present invention:

[0085] The first step is to program the single chip microcomputer 32 so that the single chip microcomputer 32 forms a complete database and numbers the single chip microcomputer 32;

[0086] The second step is to put the single chip microcomputer 32, the flow rate sensor 30, the controller 33, the signal transmission module 34 and the signal enhancer 35 into the connector 2 while producing the connector 2, so that the combination forms a complete circuit;

[0087] The third step is to number the produced connector 2 according to the number of the single chip computer 32 so that the connector 2 and the single chip computer 32 are consistent in number;

[0088] Step 4: When installing the gas pipeline 1, assemble and connect each gas pipeline 1 through the connector 2, and add a power source 31 to the connector 2 after the connection is completed, so that it can work;

[0089] Step 5: During operation, when the gas in the gas pipeline 1 passes through the connector 2, the flow rate sensor 30 on the connector 2 transmits the gas flow rate detection in the gas pipeline 1 to the single chip computer 32;

[0090] Step 6: Analyze and process the detected data through the single chip microcomputer 32, and compare it with the data in the database to form an accurate result;

[0091] Step 7: The structure analyzed by the single chip microcomputer 32 is transmitted to the signal transmission module 34 through the controller 33, and the signal transmission module 34 transmits the signal data to the satellite base station, and the data signal is sent to the terminal again through the satellite base station, so as to observe and analyze whether there is leakage through the terminal;

[0092] Step eight, when there is a leakage, the data sent back by the signal transmission module 34 is displayed on the terminal. The difference between the previous and the next data is large, thus forming an abnormal point. By analyzing the abnormal point and the corresponding number, the corresponding leakage position is determined.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
