The Design and Implementation of Telemetry Acquisition System Based on FPGA

Abstract

In order to meet the needs of telemetry test system parameters testing, we propose FPGA based on telemetry data acquisition system's overall design, and describe the methods and processes of the collection of analog signal and the reception of digital signal in detail. According to the sampling rate of the slow-changing and the rapid-changing, the frame structure is designed. Under the control of PC, data collection and coding are achived by FPGA, and real-time monitoring of data is achived through testing platform and data storage is achived by data recorders to monitor and implement, and modelsim software simulates the timing of the program. After the application of the practice, the stability and reliability of the collection system get confirmed.
