The invention discloses wireless bar code scanning equipment with an intelligent power saving function, which comprises an equipment use interval statistics module, a use frequency analysis module and a sleep mode automatic setting module. According to the wireless bar code scanning equipment, a function of carrying out statistics on a time interval of two adjacent times of scanning a bar code by a user is added into equipment system, a use frequency case of a client user is obtained by statistic analysis, and according to different use frequencies, different sleep modes are automatically set, and thus, when the client uses the scanning equipment under a high frequency, an optimal scanning effect can be achieved, and when a use frequency of the client is very low, an optimal power saving effect can be achieved.
