Design of Acquisition and Controlling System for Multi-channel Digital-analog Signal Based on FPGA
Acquisition Device is the core of this system. Acquisition module is controlled by the Ground monitoring device, which is responsible for collecting 48 routes analog signal with different sampling rate, receiving digital signals transported by RS-422 (1 route), and transmitting acquired analog and digital signals to ground monitoring device for real-time monitoring. At the same time, after mixing and compiling frame, Acquisition module sends signals to the storage module in parallel way. The collected signals are analyzed by means of the date which is read out of the storage module. This acquisition and controlling system has been applied in the check of flight test in one flight vehicle.
RS-422 interface digital-analog signal multichannel parallel way acquisition and controlling.
