| description | The invention discloses a gas pipeline leakage positioning method based on time and risk dimensions, and relates to the technical field of gas pipeline monitoring, and the method comprises the following steps: determining a gas pipeline in a traceability range as a preliminary traceability object based on alarm positioning; the maximum leakage entering concentration of each gas pipeline and the alarm pipeline is obtained, and traceability objects are screened based on the leakage entering concentration; obtaining the shortest time for the gas pipeline soil to diffuse to the communication pipeline; acquiring communication pipeline diffusion time which enables the alarm point to reach the maximum alarm concentration; obtaining the shortest diffusion time when the alarm point reaches the maximum alarm concentration based on the soil diffusion time and the communication pipeline gas diffusion time, and carrying out the preliminary sorting of the traceability objects based on the gas pipeline soil diffusion time a |
