1. A method for gas usage safety warning based on a smart gas, which is performed by a smart gas safety management platform of an Internet of Things system for gas usage safety warning based on a smart gas, comprising:
based on gas usage data, determining a gas monitoring object from at least one gas device;
determining initial objects based on the gas monitoring object and a gas usage threshold;
processing historical gas data of the initial objects by using an evaluation model to determine suspicions of the initial objects, wherein the evaluation model is a machine learning model, the evaluation model is obtained by a joint training, the evaluation model includes an object feature extraction layer, a usage feature extraction layer, a time feature extraction layer and an evaluation layer, wherein
the object feature extraction layer is used to process basic data of the initial objects to determine a basic feature vector, the basic data includes data related to a device state of the initial object;
the usage feature extraction layer is used to process the historical usage data of the initial objects to determine a usage feature vector, the historical usage data includes a usage length, a usage amount per unit time of a gas device;
the time feature extraction layer is used to process historical time data of the initial objects using gas to determine a time feature vector, the historical time data includes a start usage time point, an end usage time point, a usage count per day, and a usage count per week of the gas device;
the evaluation layer is used to process the basic feature vector, the usage feature vector and the time feature vector to determine the suspicions of the initial objects;
determining, based on the suspicions and a suspicion threshold, a target object, the suspicion threshold being determined based on feedback information of a gas user; and
sending gas usage safety warning information to a gas user corresponding to the target object.
