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

摘要

The present invention relates to a remote data acquisition device, including a shock-mounted data acquisition function, in particular a plurality of temperature, pressure, vibration, and a signal conditioner for amplifying and filtering the sensing signal inputted from the impact sensor or the like for each of the output signals that are required by the system for each sensor; And the analog multiplexer for selectively outputting the signal output from the signal conditioner according to the control of the external; And A / D converter for outputting an analog signal which is output from the analog multiplexer is selected by the data bus to the A / D conversion into a digital data signal under the control of the external; And an optical coupler for delivering discrete signal and event occurrence signal input from the outside of the device; And the latch output to the data bus under the control of the outside after storing the digital data signal is output through the optical coupler; The controls the analog multiplexer and an A / D converter to vary the analog signal input from each sensor to a digital signal, and the microcontroller controls the latch to store digital data and outputting the latched signal output from the optical combiner ; The A / D temporarily stores the digital data signal is output through the converter and a latch, and the digital data signal stored in MIL-STD-1553B bus controller for transmitting to the 1553B bus according to the protocol; And under control of the microcontroller, characterized in that it comprises a RAM which temporarily stores the impact of the shock sensor data. ; Therefore, a separate impact data, according to the present invention configured as described above acquisition device the only one of the remote data acquisition unit in the upper end projectile can be reduced to ensure that the weight of the launch vehicle with the upper part by the impact data from the remote data acquisition device to be efficiently obtained without need.
