Abstract: Aiming at the characteristics of the low-concentration gas power generation project in small scale, relatively simple process, the project information management being limited to the bottom-oriented process and object control, the network architecture and the software and hardware composition of the management information system were designed and analyzed according to the technology of low-concentration gas power generation and by taking the computer technology as the base and the network architecture as the support, the core database was established, various types of information resources in the production process were shared and orderly managed, the objectives of reducing the equipment failure rate, decreasing the equipment maintenance costs, standardizing the daily operation process and effectively managing and maintaining the core equipment were achieved, the formed modular architecture can effectively meet the management requirements of each position of the production units and the users at different levels..
