Abstract:

The design of the suicide system for a certain type of aircraft requires a knowledge of the time of corrosion of the alloy at different temperatures in seawater.Modular hardware design is adopted using the water immersion sensor as the detection unit,clock DS12887 as the timing module,C8051F040 as the microprocessor and the serial M25P80 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.
