The existing method includes: steps of user placing an order, merchant receiving the order, merchant delivering, merchant handover, user identification and confirmation, and user settlement and evaluation. The present invention combines the offline business opportunities of liquefied petroleum gas consumption by users with the Internet of Things. This existing solution targets the link of users purchasing liquefied petroleum gas, and the involved steps are ordering gas and delivering gas (excluding the household safety inspection link), and it focuses on the application of users ordering gas. The service object is liquefied petroleum gas users. It is difficult to directly apply the foregoing existing technology to the application scenarios of the supervision and evaluation of liquefied petroleum gas enterprises.

The foregoing existing solution focuses on the risk assessment of urban gas business and can conduct evaluations on liquefied petroleum gas storage and distribution stations and supply stations. This existing technology targets the evaluation of people, machines, environment, management, etc. involved in the links such as liquefied petroleum gas warehousing, loading and unloading, and filling. The service object of the foregoing existing technology is limited to liquefied petroleum gas storage and distribution stations, supply stations or enterprises, and its technical applicability needs to be improved.

[0005] In summary, the existing liquefied petroleum gas supervision technologies mainly focus on individual links such as filling, distribution, or sales, lacking supervision in the usage link of end-users (such as catering, residents, etc.). Moreover, there is a lack of a full-process supervision system covering the production, filling, transportation, storage, and end-use of gas cylinders, resulting in an incomplete supervision chain and making it difficult to achieve systematic supervision. At the same time, the current supervision is mostly short-term and phased inspections, lacking a long-term continuous supervision mechanism, making it difficult to effectively trace the source of problems and unable to meet the government's demand for full-process traceability and comprehensive supervision from the source to the end. In addition, the risk screening of liquefied petroleum gas enterprises is not accurate enough, the data is scattered and difficult to share, further leading to low supervision efficiency, and there is an urgent need to improve it through technological innovation.

The filling, distribution, delivery and recycling records involved in the whole transfer operation process are the whole-process operation data. A process formed after the gas cylinder goes through the filling, distribution, delivery, recycling and other links is a gas cylinder use transfer. In the same gas cylinder use transfer, the records of the filling, distribution, delivery, recycling and other links of the gas cylinder have a unique same transfer batch number. If there are transfer link records with the same gas cylinder number but different transfer batch numbers within a certain period of time, it means that the gas cylinder has experienced different use transfer processes.
