In this paper, SCM AT89C52 voice and the voice chip ISD2560 of storage systems, and the voice of the Sub-taking, portfolio intervals, with LCD liquid Crystal display module OCMJ2X8, can achieve a simple function of the bus station reported. System hardware circuit is simple, easy adjustment, cost-effective and practical.
