Application scenarios of this dataset are as follows: 1. For gas utility enterprises: This dataset enables refined hierarchical management of equipment operational health by quantitatively evaluating the operating status of gas meters. Enterprises can optimize meter inspection, maintenance and replacement plans based on the evaluation results, improve the level of full lifecycle management of equipment, reduce the risk of sudden faults, and thus ensure continuous and stable gas supply for users. 2. For government departments: This dataset provides support for macro monitoring and trend analysis of operating risks of gas facilities under their jurisdiction. Governments can carry out hidden danger investigations in key areas based on the evaluation results, improve the urban gas operation safety supervision mechanism, and realize rapid decision-making and precise scheduling during emergency response. 3. This dataset also provides support for product improvement and optimization of gas meter manufacturers. 1.
