摘要
针对某型航行器自沉系统中,需要掌握某合金材料在海水中因不同温度条件下的受腐蚀时间长短。采用模块化硬件设计,使用浸水传感器为检测单元、时钟芯片DS12887为计时模块;以C8051F040为微处理器和串行M25P80为存储模块设计浸水时间记录系统。外部数据通信采用CAN总线。通过实践证明,DS12887时钟能在掉电后正常运行,但时间长,需要新设定时间,以便准时记录。
The design of the suicide system for a certain type of aircraft requires a knowledge of the time of cor- rosion of the alloy at different temperatures in seawater. Modular hardware design is adopted using the water immer- sion sensor as the detection unit, clock DS12887 as the timing module, C8051F040 as the microprocessor and the serial M25PS0 as the storage module to record the immersion time External data communication adopts the CAN bus. Practical uses show that the clock DS12887 work properly at the loss of electricity, but requires a resetting of time for accurate record if the loss lasts Very long.
