The present invention discloses an intelligent ammeter software reliability detector and a detection method for intelligent ammeter software reliability. The detector consists of an embedded device of a WinCE operating system, and software reliability detection software equipped with a self-designed intelligent ammeter. According to the intelligent ammeter software reliability detection software, a software reliability analysis technology and a decompilation technology are used to design the intelligent ammeter software reliability detector. Functions of the detector are: carrying out disassembling through a binary code of the intelligent ammeter; then decompiling the computer language to be a senior programming language; and finally carrying out software reliability detection based on a static structure on the decompiled C language.
