The invention discloses an intelligent and electronic pain scoring system and method. The system comprises a data acquisition module, a data processing module and a data storage and display module, wherein the data acquisition module is used for acquiring pain data information of a user; the data processing module is used for receiving the pain data information from the data acquisition module, and analyzing the pain data information so as to obtain a pain evaluated value and a pain control requirement of the user; and the data storage and display module is used for storing, displaying and outputting the pain evaluated value and pain control requirement, obtained by the data processing module, of the user and an analgesia control degree. According to the system and method, large-scale evaluation in hospitals and evaluation methods of different hospitals are unified, so that corresponding unnecessary errors are eliminated to facilitate the statistical communication. The system is easy to operate, time-saving, labor-saving and stronger in intuition, is capable of decreasing corresponding workloads, improving the working efficiency, preventing interferences of human factors, and can be directly displayed on display screens.
