摘　　要：在遥测系统中,针对传统存储系统硬盘的功耗高、发热高、噪声大、访问速度低的问题,设计了以FPGA为主控单元,以LVDS为图像数据传输和读取的接口。以图像存储、图像传输、长线读数和实时监测为主要功能模块。以FLASH为存储单元,合理地选择了存储模块的工作模式,根据可靠性和模块化的设计原则,结合任务要求与功能指标要求,提出了高速图像存储系统的设计方案;测试与数据分析结果表明,存储速度可以达到60 Mbyte/s。具有操作简易,抗高过载,集成度高,工作稳定,耐高温的特点。本系统设计完全符合任务要求,达到规定的性能指标。In the telemetry system,the problems of high power consumption,high heating,high noise and low access speed of the hard disk of the traditional storage system are discussed.The interface of FPGA as main control unit and LVDS as image data transmission and reading is designed.The main functional modules are image storage,image transmission,long line reading and real-time monitoring.Taking FLASH as the storage unit,the working mode of the storage module is reasonably selected,and according to the design principle of reliability and modularization,the design scheme of the high-speed image storage system is put forward in combination with the functional index requirements and the task requirements.The test and data analysis results show that the storage speed can reach 60 Mbyte/s.It has the characteristics of simple operation,high overload resistance,high integration,stable work and high temperature resistance.The design of the system is fully in line with the requirements of the task and meets the specified performance indicators.
