The invention provides a stack self-inspection method and a stack self-inspection device. The method comprises the following steps: a main function for controlling a program calls a preset stack self-inspection subfunction to perform self-inspection when the program starts, wherein the preset stack self-inspection subfunction defines a preset size of local variable array and values of all local variables in the local variable array, and the preset size is much larger than the size of a stack used when the subfunction enabling the program to operate normally is called; after the preset stack self-inspection subfunction sends a return value to the main function, the main function is controlled to call the subfunction enabling the program to operate normally, and a compiler distributes a stack area used by the preset stack self-inspection subfunction for the subfunction enabling the program to operate normally; and when the self-inspection of the preset stack self-inspection subfunction is not passed, the program is positioned in an idle loop dead state and no longer returned. According to the method and the device provided by the invention, the C language stack can be effectively and rapidly self-inspected, operation reliability of a system is not influenced, and operation efficiency of the program is improved.
