Instruction self-inspection method for improving reliability of electronic time fuse

Abstract

The invention discloses an instruction self-inspection method for improving the reliability of an electronic time fuse. The instruction self-inspection method comprises the following steps: adding an operation instruction, namely, a self-inspection instruction, in a setting instruction set; when a setting recognition module receives the self-inspection instruction, sending the self-inspection instruction to a self-inspection logic module after recognition; by means of the self-inspection logic module, enabling an instruction self-inspection excitation generation module to generate the self-inspection instruction and sending to a circuit core work module, namely, a time fuse timing module, executing interior self-inspection, namely, on-chip function logic self-inspection by the time fuse timing module, detecting whether the circuit is normal or not, and storing and responding the self-inspection result; and meanwhile, enabling instruction self-inspection excitation, starting to receive and judge the self-inspection result, and writing the self-inspection result and feeding back to the self-inspection module after the instruction self-inspection process is finished. The method does not need to increase the hardware overhead of a fuse system, so that the reliability and the generality of the electronic time fuse are improved, the cost is saved and the method can be widely popularized.

Description

[0001] technical field [0002] The invention relates to a command self-inspection method for improving the reliability of an electronic time fuze, which belongs to the technical field of electronic detection. Background technique [0003] With the rapid development of electronic technology, electronic components are constantly developing in the direction of miniaturization. Electronic time fuze is a new type of time fuze developed to meet the needs of the development of electronic systems, especially to meet the requirements of time fuze timing accuracy, action time, generalization, serialization, and standardization. Compared with mechanical time fuzes, electronic time fuzes have many advantages such as high timing accuracy, long action time, 100% non-destructive inspection, and easy use with directors. [0004] In the field of electronic systems, electronic time fuze circuits are usually used to complete timing control functions such as self-destruction and ignition. In...
