Design of Data Acquisition and Transmission System based on Single Chip Microcomputer

Data acquisition technology is a practical electronic technology, which is widely used in signal detection, signal processing, instrumentation and other fields.In recent years, with the continuous development of digital technology, data acquisition technology also presents a characteristic of faster processing and more channels.The data acquisition is to measure and control the physical quantity such as temperature, pressure, flow, speed, displacement, light intensity, sound, etc., Convert the physical quantity into electric signal of simulation physical quantity through the sensor, then process the analog electric signal and convert it into signal that computer can recognize the digital, then sent to the computer processing, storage, transmission and display.This paper describes the hardware and software system construction of data acquisition and transmission system.
