Automatic verification and automatic repair method of control software of numerical control system

Abstract

The invention provides an automatic verification and automatic repair method of control software of a numerical control system. The automatic verification and automatic repair method sequentially comprises the following steps: step 1: performing legitimacy verification on operation version by the numerical control system, and finishing the verification when the first verification result is yes; step 2: sequentially performing first automatic repair and second verification on the operation version by the numerical control system when the first verification result is no, and finishing the verification when the second verification result is yes; and step 3: performing second automatic repair and third verification on the operation version by the numerical control system when the second verification result is no, finishing the verification when the third verification result is yes and prompting a user to notice the appearance of hardware failure when the third verification result is no. According to the automatic verification and automatic repair method disclosed by the invention, the number of maintenance times of the numerical control system can be greatly reduced, and economic loss of both a manufacturer of the numerical control system and the user of the numerical control system is further reduced.

Description

technical field [0001] The invention relates to the field of numerical control, in particular to a method for automatic verification and automatic repair of control software of a numerical control system. Background technique [0002] The current CNC system generally adopts embedded system, and its system architecture generally adopts the mode of hardware + embedded operating system + control software. When the control software of the CNC system cannot start or work normally due to malicious attacks or software upgrade failures, the existing CNC system cannot automatically judge whether the control software can run normally, and the user can only use the CNC system Return it to the factory for repair or have it repaired on-site by specialized service personnel. And the repeated maintenance of the numerical control system causes different degrees of economic losses to both the numerical control system manufacturer and the numerical control system user. [0003] In addition,...
