Design and Implementation of Temperature Data Collection System Based on USB

This paper introduces the design and implementation of the temperature data collection system based on the universal serial bus(USB) technology,the system is developed on the basis of the integrated use of USB interface technology,the single-chip microcomputer technology as well as the data collection technology.The design of temperature data collection system is made up of three parts:temperature data collection module,data transfer module and PC application program,which describes the configuration of temperature data collection module and data transfer module as well as the hardware implementation in the study.It analyzes the design theory and programming method of the USB communication software in detail during software design and provides development tool and implementation flow of USB firmware and driver program.The system implements data collection and control for temperature collection equipment through USB bus.The experiment shows that the system has the advantages of high speed,real-time,high cost-performance.
