Methods and Internet of Things (IoT) systems for safety management of smart gas underground gas pipeline networks

An Internet of Things (IoT) system for safety management of a smart gas underground gas pipeline network, wherein the IoT system comprises a smart gas user platform, a smart gas service platform, a smart gas safety management platform, a smart gas pipeline network device sensing network platform, and a smart gas pipeline network device object platform that interact in sequence, and the smart gas safety management platform is configured to:

• obtain basic monitoring information of at least one pipeline network partition collected by distributed monitoring components arranged at a plurality of monitoring points based on the smart gas pipeline network device object platform through the smart gas pipeline network device sensor network platform, the basic monitoring information being collected at a preset monitoring frequency;
• generate at least one key monitoring point and monitoring content of the at least one key monitoring point based on the basic monitoring information, a pipeline network structure map, and a gas pipeline feature in a pipeline corridor;
• determine 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, and 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;
• adjust the preset monitoring frequency of the distributed monitoring components located at different key monitoring points and at areas surrounding the different key monitoring points based on the performance allocation plan for the smart gas safety management platform;
• and
• generate an alarm message based on an inspection result of the inspection robot and send the alarm message to the smart gas user platform through the smart gas service platform;
• wherein
• the smart gas safety management platform is configured to:
• predict a data feature of the at least one key monitoring point through a data prediction model based on the at least one key monitoring point and the monitoring content of the at least one key monitoring point;
• determine a candidate performance allocation plan according to a proportion of an amount of data transmitted to the smart gas safety management platform within a same time period based on the data feature;
• perform a plurality of rounds of iteration on the candidate performance allocation plan until a first iteration completion condition is met;
• determine the performance allocation plan for the smart gas safety management platform based on an iteration result;
• and
• wherein each of the plurality of rounds of iteration includes:
• calculating an evaluation value of the candidate performance allocation plan;
• and
• adjusting the candidate performance allocation plan based on the evaluation value to obtain an updated candidate performance allocation plan, the evaluation value including a plurality of sub-evaluation values, and the sub-evaluation values being related to data collection efficiency of the at least one key monitoring point.
