FIELD: seismology, national survey and data processing systems of geophysical measurements for earthquake forecasts. SUBSTANCE: programs of polling of linear cruciform groups are formed on computer and recorded in Winchester. Present program of polling is sent from computer into programmable circuit of measurement retrieval. Channel commutator in correspondence with present program conducts cyclic interrogation of single transducers-meters by connection of their outputs to input of analog-to-digital converter with discrete time interval set by program. Each connection of transducer-meter is accompanied by activation of analog-to-digital converter, which transforms amplitude of signal of transducer to digital code by standard quantization scale. Numbered readings are recorded in buffer-former. Measurement recordings by one of coordinates are formed after interrogation of all transducers of one group. Measurement recordings of other linear groups are gained in same manner. EFFECT: enhanced authenticity, precision and timeliness of prediction of earthquakes. 3 dwg |
