1. A method for safety monitoring and early warning of a smart gas pipeline network implemented by a smart gas safety management platform, wherein the method comprises:
obtaining basic monitoring information of at least one pipeline network partition collected by distributed monitoring components arranged at a plurality of monitoring points, the basic monitoring information being collected at a preset monitoring frequency;
identifying abnormal information in the basic monitoring information;
determining at least one abnormal information distribution map based on the abnormal information and a pipeline network structure map;
determining a change feature of the abnormal information along a direction of the pipeline network based on the abnormal information distribution map;
determining a monitoring point whose change feature meets a preset change condition and an abnormal information type of the monitoring point as at least one key monitoring point and a monitoring content of the at least one key monitoring point;
determining an inspection plan and a performance allocation plan for the smart gas safety management platform based on the at least one key monitoring point and the monitoring content of the at least one key monitoring point and the basic monitoring information, the inspection plan being executed by at least one type of inspection robot, the performance allocation plan for the smart gas safety management platform at least including a maximum performance occupancy of the smart gas safety management platform for processing monitoring data, and the monitoring data referring to data in areas where different key monitoring points are located;
adjusting the preset monitoring frequency of the distributed monitoring components located at the different key monitoring points and areas surrounding the different key monitoring points based on the performance allocation plan for the smart gas safety management platform; and
generating an alarm message to be sent to a user terminal based on an inspection result of the inspection robot.
