Data acquisition and communication system based on PC

This paper introduces the data acquisition system based on PC by beginning with the hardware formation and working principles of the system and emphatically exploring the communication principles and approaches between PC and single-chip computer together with the points of VB communication system programming.For the data acquisition system program to be characterized by the super performance of confidential maintenance,this paper finally discusses the encryption principles and approaches of single-chip application system.The application of the system can help solve the problem of mass-data acquisition,storage and complicated chart display.
