Abstract: Effective management of system parameters of seismic instruments is very important for long-term and stable process. For some problems in EDAS-24IP parameter management model, a new type of digital seismograph parameters model based on Linux character device is developed. This model has a great improvement in stability, availability, real-time response and so on. The problem that system can't be restarted because of the loss of parameters' files disappeared.

Key words: Digital seismograph, Embedded development, Parameters management
