The invention discloses an intelligent encoding system for detecting a live tool and particularly relates to a system for performing information query and remote monitoring and management on a tool byscanning a two-dimensional code on a tool tag. The system includes an intelligent code management platform, a two-dimensional code tag printing device and a two-dimensional code scanning device. Theintelligent code management platform automatically encodes tool information and generates the two-dimensional code, the two-dimensional code tag printing device intelligently selects a corresponding mode to print the two-dimensional code tag according to the tool type, the two-dimensional code tag is pasted to the tool, the two-dimensional code scanning device scans a tool position two-dimensionalcode and a corresponding position tool two-dimensional code, and the tool and the corresponding position information are bonded and recorded in the intelligent code management platform. According tothe system, the two-dimensional code is scanned through a mobile phone APP, the whole-process monitoring of the production and usage of the tool is performed, the system has functions of test validityperiod proximity prompt and out of validity, and the full-lifecycle management of the tool is achieved.
