Abstract


Telemetry refers to an object at a distance parameter for detection, and to store the measurement results to the receiver apparatus or a next measurement technique . And because of the system formed by this technique is called telemetry system . Telemetry system is designed to be able to master a variety of timely and complete telemetry parameters , telemetry equipment performance is critical. Image telemetry system is a set of image acquisition , storage, transmission as one of the telemetry processing systems for recording different time telemetry status object scene provides a more direct method. This topic \The system consists of the video image acquisition unit, an image storage unit , the radio frequency unit and a data reading unit of four parts . Image acquisition part is mainly constituted by the ADV7180 and FPGA , the CCD image sensor PAL system video signal into a digital signal. Image storage part is mainly constituted by Flash and FPGA recorded video image data . Mainly by the nRF24L01 RF and FPGA composition. In order to quickly read the stored image data, the system design also includes USB2.0 interface , you can quickly read the data in Flash . Overall system design using Altera's second-generation Nios Ⅱ soft-core processor as the core , combined with its rich IP cores , the use of single-chip FPGA implementation of image acquisition and storage. The design is completed the system hardware , FPGA processes and systems software design , and system debugging , design fully meet the requirements.
