The Research of Detection Guiding Technique in Embedded System

Embedded device boots operating system directly after power, which possible can lead to the device´s abnormal starting in case that some blocks of operating system files have been damaged, EEPROM hardware goes wrong temporarily and software runes out etc. It also have no fault-tolerant processing ability, thus the reliability is reduced greatly. To solve this problem, this paper proposes a kind of detection guiding technique. On considering fault tolerance, reliability and real-time, this technique verified in low-energy x-rays lead room, is safer and more reliable than the method that common devices boot operating system directly after power or watchdog reset, and can real-timely control the latest state of the device.
