Design of Software for Data Collection and Transmission

System

ABSTRACT

Data acquisition and transmission system has been widely applied in the fields of industrial production、agricultural production and scientific research. In addition, the remote system of data acquisition and transmission, which completed by the computer, plays an increasingly important role. This system can collect, monitor and record the technical parameters on-site in the production process. It plays a vital role to improve the product quality and increase production efficiency. This system can catch a large number of dynamic information available in the scientific study. It’s an important tool to study various changes of process.

Data acquisition system is the collection of analogy signals exported by sensors, and the conversion to digital signals which can be identified by computer, and sent to receiver to record or display for the aim of monitoring certain physical signals. When the hardware was determined, reasonable design of software can make the system realize more function and obtain higher efficiency.

This system realizes data acquisition and transmission by the Single Chip Microcomputer for the core of control, and realizes direct control to the internal unit and external chips by the using of assembly language to program, and realizes the parallel working of Single Chip Microcomputer by using the interrupt mode for the main way to information exchange. The software of system is designed to finish the control of eight analogy signal acquisition and analogy-to-digit conversion, and to control communication of the Single Chip
