Infrasound sensor array telemetry system of micro-electromechanical system

Abstract

The invention relates to an infrasound sensor array telemetric system of a micro-electronic mechanical system in the telemetric field. A data detecting control system controls a scanning orientation control system; the scanning orientation control system controls an ultralow-frequency sound wave emitting system and a micro-electronic mechanical frequency coupling sensor array and transmits feedback information to a data analyzing system; an ultralow-frequency sound wave bunch emitting system emits detecting sound wave to a geologic structure, and the detecting sound wave passes through the micro-electronic mechanical frequency coupling sensor array; the micro-electronic mechanical frequency coupling sensor array receives low-frequency signals, carries out frequency mixing and coupling for the low-frequency signals, transforms the low-frequency signals into medium-frequency signals; measuring frequency coupling signals are transmitted to an analog-to-digital conversion data transmitting network to carry out analog digital signal conversion; measured data is transmitted to a data analyzing system and a data detecting and controlling system to carry out information exchange; and analyzed data result and the feedback information are transmitted to the data detecting and controlling system. The system has the advantages of fast testing speed, strong response ability and high quality of data transmission.
