Design of Data Acquisition and Communication System of Remote Controller

摘要

In this paper, a kind of data acquisition and communication system of remote controller was designed. Components were selected appropriately in the system, so reduce the system cost, realize the miniaturization of the system volume and real time data acquisition and disposal, and a new method of long distance communication between SCM and computer is designed. Some chips are used to receive and send data and perform the conversion of electric level. C language is employed to perform the long distance real-time data transmission. The system structure, communication theory and software design are detailed. The data acquisition and communication module have been used in actual measure and control system, and it performs the task of long distance data acquisition and communication properly. It can be used to complete the communication of host and multi-SCM after being extended little.
