Abstract: Aiming at the poor universality, compatibility and extensibility of the existing remote monitoring system, a five layer architecture of remote monitoring system was proposed. The five layer architecture consists of presentation layer, business and logic layer, persistent layer, resource abstract layer and device adapter. Using the configurable page component for registration and data binding, the customization of the page was realized. The complexity and coupling of the system could be reduced by establishing components container in the business and logic layer and classifying the corresponding components. Through the establishment of the abstraction and meta abstract tree of the entity, behavior and state of the underlying equipment, the abstract specification was formulated and the adaptation program was written for its communication interface, which shielded the difference of the underlying equipment and ensured the versatility and expansibility of the system. The results indicate that the large difference among the equipment and the complex network communication environment are adapted, the underlying equipment can be free to join or exit the system, a lot of page logic development is avoided, the development costs and cycle are reduced.

Key words: remote monitor; generalized architecture; adapter; abstract programming
