ON-BOARD TELEMETRY DATA ACQUISITION SYSTEM WITH SHOCK DATA RECORDING FUNCTION FOR SPACE LAUNCH VEHICLE

摘要

The present invention relates to an on-board remote data acquisition device including a shock data acquisition function. In particular, a signal required by a system is amplified and filtered by a plurality of temperature, pressure, vibration, and shock sensors. A signal regulator for outputting each; An analog multiplexer for selectively outputting a signal output from the signal controller according to external control; An A / D converter for converting an analog signal selected and output from the analog multiplexer into a digital data signal and outputting the analog signal to a data bus according to external control; An optical coupler for transmitting a discrete signal and an event generation signal input from an external device; A latch for storing the digital data signal output through the optical coupler and outputting the digital data signal to the data bus under external control; A microcontroller for controlling the analog multiplexer and the A / D converter to convert the analog signal input from each sensor into a digital signal, and controlling the latch to store and output the digital data signal output from the optical combiner in a latch; ; A bus controller which temporarily stores the digital data signal output through the A / D converter and the latch and transmits the stored digital data signal to the 1553B bus according to MIL-STD-1553B protocol; And a RAM for temporarily storing shock data of the shock sensor under the control of the microcontroller.;Therefore, according to the present invention configured as described above, it is possible to efficiently obtain the impact data from the remote data acquisition device without the need for a separate impact data acquisition device so that only one remote data acquisition device is mounted on the upper end of the projectile. Can reduce the weight of;Mounted Telemetry, Impact Data Acquisition Unit, Remote Data Acquisition Unit, MIL-STD-1553B, A / D Converter, Interrupt Mask
