摘要: A computerized, automatic, portable general earthquake observation system is disclosed. The includes a microprocessor and associated computer program stored in memory, which control other components of the through bus. Input channels for receiving signals from sensors are connected to signal conditioning module selectively coupled an analog-to-digital conversion module, both under microprocessor. pre-event data memory stores digitized sent along separate bus by module. Data analyzed information regarding disposition archival storage on internal recorder using or transmission desired external various possible modems. also time reference automatic calibration operator interface
