With the rapid development of science and technology as well as the petroleum industry, the role of a collective procurement monitoring system in petroleum resource management has become increasingly important. This article proposes a design scheme for an oil collective procurement monitoring system based on Infrastructure-as-a-Service (IaaS) cloud platform. By applying Internet of Things (IoT) technology and cloud platform technology to the oil field collective procurement process, it is possible to monitor the process in real-time, facilitate data collection, and analyze and predict data. This system utilizes the flexibility and scalability of IaaS cloud platforms with the aim of improving real-time monitoring capabilities and data processing efficiency in the collective procurement process.
