Design of Be Able to Withstand High Overload Impact High Speed Signal Storage

摘要

Based on high-speed memory chips AT25DF641, able to withstand high overloads and the performance does not change the silicon produced the oscillator SIT8003 and high-performance microprocessor the PIC16F882, using C language programming, the realization of monolithic high-speed signal acquisition and storage function. The storage performance is as follows: analog signal (built in 10 bit A / D converter) acquisition speed is 30 us / times, digital signal acquisition speed is 0.2μs / times; storage speed is 10μs / Byte, It's storage capacity is 64Mbit; Able to withstand 150000g overload impact. The storage has 4 acquisition channels (can be expand to 13 analog signal acquisition channels max.). The mode of input may be analog signal, digital switch quantity, analog switch quantity, negative pulse and other types of signals. The memory circuit is simple and reliable, small volume, It can withstand high overload impact. It can be used for record of detector echo wave of proximity fuzes, record of output signal process of electronic fuze, and other occasions, and can also use a combination with an acceleration sensor, record by the acceleration change case of fuze, The hard target fuze overload changes of penetration process.
