Abstract
Aiming at the requirements of temperature measurement accuracy and acquisition and transmission speed in indus-trial production,this paper designs a multi-channel high-speed temperature acquisition and transmission system based on field-programmable gate array.First of all,the conditioning circuit is designed to ensure that the temperature signal collected by the eight-way K-type thermocouple is reliable and undistorted.Secondly,the AD7686 chip with low delay is selected to accurately con-vert the analog to digital,and the AD conversion circuit control and frame format processing logic are integrated in the monolithic FPGA,and the temperature data is stored in the FPGA.In addition,FT232HL bridge chip is used to realize the computer to read and save the data stored in FPGA and display it in real time.Finally,an experimental platform is set up to test the system.The ex-perimental results show that the acquisition accuracy of the system is not more than±0.19%,and the data return speed is 40.78 M/s,realizing accurate temperature measurement and high-speed transmission.The system is expected to be widely used in the field of hot processing.关键词
