[0022] It can be understood that, with the rapid development of economy, the demand of the country for energy such as oil and natural gas is increasing, and pipeline is an important way to transport oil and natural gas economically. For natural gas pipeline, typhoon storm, high temperature and high humidity, high salt, flood disaster, collapse, debris flow, landslides, sun exposure forest fire and third party damage will cause damage risk to the buried natural gas pipeline along the planned route. The main damage to the pipeline body is caused by the environment structure along the pipeline, for example, high temperature and high humidity, high salt, etc. will corrode the pipeline body, cause pipeline damage and even leakage, external factors such as earthquakes, landslides, debris flow, etc. around the pipeline will cause the pipeline to shift, break and rupture, the quality of the pipeline body will be damaged due to problems such as welding during pipeline construction, damage to the protective layer, and the pipeline will be damaged due to third party construction such as excavator operation, vehicle rolling on the pipeline and causing collapse. Therefore, in order to ensure the safe operation of the natural gas pipeline, it is necessary to strengthen the safety control of the natural gas pipeline, and timely find the risk, so as to avoid the leakage, fire and explosion accidents of the natural gas pipeline.

[0023] Therefore, in order to realize the online monitoring function and timely warning function of the natural gas pipeline, the utility model provides a natural gas pipeline operation early warning system for detecting the natural gas pipeline, referring to Figure 1 , the natural gas pipeline operation early warning system comprises:

[0024] The pipeline detection assembly 10 is arranged around the natural gas pipeline; the pipeline detection assembly 10 is used for positioning the position of the abnormal point of the natural gas pipeline and outputting the level signal representing the position of the abnormal point when the abnormality of the natural gas pipeline is detected;

[0027] It can be understood that for natural gas pipeline, typhoon rainstorm, high temperature and high humidity, high salt, flood disaster, collapse, debris flow, landslides, sun exposure forest fires and third party damage, etc. will cause damage to the buried natural gas pipeline under the planned route. In order to ensure the safe operation of the natural gas pipeline, the inspection personnel will manually inspect along the pipeline route, and when the natural gas pipeline is found to be abnormal, the inspection personnel will timely alarm and notify the pipeline management personnel to monitor the pipeline in real time to ensure the safety of the pipeline. However, the above-mentioned pipeline safety protection method needs the inspection personnel to monitor the pipeline at all times, which not only has high artificial work intensity, but also has low monitoring efficiency. Therefore, the utility model provides a natural gas pipeline operation early warning system, which sets a pipeline detection assembly 10 around the natural gas pipeline, so that the pipeline detection assembly 10 can timely issue the position of the abnormal point of the natural gas pipeline when detecting the abnormality of the natural gas pipeline; and sets an image acquisition assembly 20 along the natural gas pipeline, so that the image acquisition assembly 20 can collect image information at multiple angles and multiple directions along the pipeline, and the central processing assembly 30 can generate corresponding abnormal pipeline image information according to the position of the abnormal point of the natural gas pipeline and the image information, and perform image prompting or alarm prompting based on the abnormal pipeline image information. Thus, the online monitoring function and timely early warning function of the natural gas pipeline are realized, the artificial work intensity is reduced, and the monitoring efficiency is improved.

[0028] In the embodiment, the pipeline detection assembly 10 is arranged around the natural gas pipeline to detect parameters of the natural gas pipeline in real time, such as stress parameters, vibration parameters, temperature parameters, speed parameters, pressure parameters, etc., and timely locate the position of the abnormal point of the natural gas pipeline when any parameter is detected to be abnormal, and output a level signal representing the position of the abnormal point to the central processing assembly 30, so that the central processing assembly 30 timely makes a prompt operation.

Through the above arrangement, the pipeline detection assembly 10 detects the stress, vibration, temperature and other parameters of the natural gas pipeline to determine whether the parameters of the natural gas pipeline are abnormal, and once the abnormality is detected, the position where the abnormality occurs is located to determine the position of the abnormal point of the natural gas pipeline, and the position of the abnormal point is output to the central processing assembly 30 in the form of a level signal, thereby realizing the parameter monitoring and timely warning function of the pipeline. The image acquisition assembly 20 acquires images along the natural gas pipeline in real time and outputs corresponding image signals to the central processing assembly 30, thereby realizing the image monitoring function of the pipeline. The central processing assembly 30 obtains abnormal pipeline image information according to the position of the abnormal point of the natural gas pipeline and the image information of the natural gas pipeline. Thus, the online monitoring function and the timely warning function of the natural gas pipeline are realized, which not only reduces the manual work intensity, but also improves the monitoring efficiency.

[0029] It should be understood that the natural gas pipeline map is pre-prepared by a worker and burned into the memory of the central processing assembly 30. When the central processing assembly 30 receives the position of the abnormal point and the real-time image information, the natural gas pipeline map stored in the memory is called, and the natural gas pipeline map is marked according to the position of the abnormal point and the real-time image information, thereby obtaining the abnormal pipeline image information.
