Because the environmental conditions may vary from one pipe section to another, for example, the gas pipeline may need to be divided into different pipe sections for monitoring through different terrain, soil conditions, or areas of different environmental pollution. Therefore, in the actual dividing process, the lengths of each pipe section may not be the same, and need to be preconfigured and adjusted according to the actual situation, which is not limited in the embodiment of the present application;

the preset concentration threshold value can be preset according to the actual condition of the gas pipeline and the related concentration standard; when the concentration of combustible gas exceeds a preset concentration threshold, an explosive mixture may be formed, and once an ignition source is encountered, a fire or explosion may be initiated; therefore, by monitoring the concentration of the combustible gas and ensuring that it is within a safe range, the occurrence of fire can be prevented.

By setting a plurality of preset concentration difference intervals, if the concentration difference value changes in a certain preset concentration difference interval, the corresponding preset monitoring frequency does not need to be changed, so that the condition that the monitoring frequency is frequently adjusted is reduced.
In the above embodiment, if the concentration difference is smaller, a higher monitoring frequency can be configured in the corresponding concentration difference interval, so that the concentration information of the pipe section can be obtained in time, and the safety is improved; if the concentration difference value is judged to be larger, the corresponding concentration difference value interval can be configured with lower monitoring frequency for monitoring so as to reduce the waste of monitoring resources; the monitoring frequency of different pipe sections is dynamically adjusted, so that the monitoring requirements of different pipe sections are met conveniently, and the adaptability of a monitoring system is improved.

step S301, obtaining a combustible gas concentration change value of a pipe section corresponding to a pipe section number after a preset time length;
the preset duration is a preset time interval length, for example, may be set to 5 minutes or 10 minutes, etc.; the combustible gas concentration change value is the difference value between the current combustible gas concentration and the combustible gas concentration after the preset time, the difference value is a negative value when the combustible gas concentration is increased, and the difference value is a positive value when the combustible gas concentration is reduced;
step S302, judging whether the concentration change value of the combustible gas is smaller than a preset concentration change threshold value; if yes, go to step S303; if not, not executing any operation;

step S401, determining corresponding concentration monitoring interval duration according to a preset monitoring frequency;
