Mediation-based Middleware for Heterogeneous Instruments Unified Access

Aiming at the problems in the earthquake precursory industry that it is heterogeneous to access devices, data processing method is single, and it is difficult to manage all the devices, this paper brings up a mediation-based middleware for heterogeneous instruments, which can shield the physical connection heterogeneity and instrument protocol heterogeneity, and it can convert heterogeneous device to virtual device with unified properties, command set and data result set. A typical scene is presented to validate the method is feasible.
