可循环存储的记录器控制系统设计

Design of Recorder Control System with Recyclable Storage

为适应现代记录仪系统地面测试时的多次实验、循环存储、数据分类需求,设计了一种按上电次数循环存储的记录器控制系统。该系统采用STC15单片机的比较器作为电压监测模块,使用FPGA作为主控,通过长距离的LVDS线连接存储模块的FPGA。存储模块实时存储数据并检测比较器的输出,在系统完全断电前存储Flash的地址信息,达到多次上电存储的目的。通过大量上电掉电实验得知,该系统可以满足按上电次数存储的需求,为记录器的设计提供了一种新的思路。

In order to adapt to the needs of multiple experiments,cycle storage,and data classification during the ground test of modern recorder systems,a recorder control system that is cyclically stored according to the number of power-on times is designed.The system uses STC15 microcontroller comparator as the voltage monitoring module and the FPGA as the main control,connecting the memory module FPGA through long-distance LVDS lines.The storage module stores data in real time and detects the output of the comparator.Before the system is completely powered off,the address information of the Flash is stored to achieve the purpose of multiple power-on storage.Through a large number of power-on and power-off experiments,it is known that the system can meet the requirements of storage by the number of times of power-on,which provides a new idea for the design of recorders.
