Abstract:Tmis paper introduced the real-time processing system in micro-computer,using the hard-ware interruption and clock interruption and the technique that the programs can be stayed in a internal memory of computer. The system has foreground and background processing function; multi-channel programs can be run in the CPU of main computer at the same time;the real-time processing of the data collecting,event detecting,data dumping and earthquake locationetc. can be carried out.The system is suitable to the regional telemetric seismic network or the local telemetric seismic network.
