Study On The Multi-type Data Vehicle Data Recorder

With the continuous development of testing technology and recording instrument on diversification, intelligent demand, Embedded system used in large and complex system record instrument is inevitable.A new generation of embedded system not only in processing ability far outweigh the common single-chip microcomputer system, and abundant peripheral resources also greatly shorten the product development cycle.At the same time, Embedded system can better adapt to the harsh environmental conditions.This paper makes a study of the embedded system for a certain type of weapons and equipment research and development of the application of multi-type data vehicle data recorder.Realize the CAN data, RS422data, VGA high-definition image, PA1system image weapon system data collection, record and playback, data transfer function.Multi-type vehicle data recorder hardware platform using the PC104, FPGA and DSP and embedded structure, software system uses Embedded Visual C++, Verilog HDL, Lab View development, etc.This paper main job is to:1、Based on a certain type of weapon system work flow, combine the product environment adaptability and reliability requirements, Multi-type vehicle data recorder choose embedded system for system development.2、Describes the multi-type vehicle data recorder overall design plan, introduced the structure of the hardware system and software system structure design.3、For weapon system working environment requirements, introduces the multi-type vehicle data recorder engineering design method, And introduces the machine test and test.
