The invention belongs to the power technology field, especially relates to a power distribution network problem code management system. A coded data memory is connected with a host computer, and the host computer is respectively connected with the coded data memory and a coded data input unit. The power distribution network problem code management system is advantageous in that a problem code generator is externally connected with a first manual input device, or is provided with the first manual input device in a built-in manner, and then identification codes are additionally provided during information code generating process without requiring the host computer, and then types and contents of coding objects are classified and identified, and then the additionally-provided identification codes are scanned to acquire the related information codes directly, and therefore speed of a user of searching the required information is accelerated, and at the same time, the coding objects can be static, dynamic, or interactive information, and then the range of the information provided for the user is wider.
