The data acquisition system is the link between the digital domain and analog domain. It has an very important function. The system applies ADC0809 as a high speed data conversion circuit to 8 road data real-time acquisition, implementation of the collected data to convert the analog quantity to digital quantity, and the transmission of real-time data were collected through RS232 to the upper PC. This system will be popular in the A/D conversion technology and single-chip microcomputer technology effectively combined, realize the high-speed communication and data exchange. System can carry on the monitoring at the same time, to the multiple points and able to communicate with computer, easy to realize the man-machine dialogue. The software is partly programmed with VC++. The software can realize the function of monitoring and controlling the whole system. It designs much program like data-acquisition treatment,data-display and data-communication ect.
