| Abstract: | According to the actual function requirement of the mechanics experiment or the production processing,a data acquisition system for an electronic extensometer is designed with a high-performance single chip microcomputer,STC89C52RC.A high-precision dc chopper steady zero type operational amplifier,TLC2652 is used as the amplification chip.A 16 bits Σ-Δ A/D conversion chip,AD7705 is used as A/D conversion device.Keil C51 is used to compile the program of the single chip microcomputer,VB is used to design and develop the software of the upper computer.The cost of the system is low,the volume of the system is small,and the portability of the system is good.The test experiment result shows that the system has a high accuracy a good real-time performance,the system is suitable to the practical function requirement of the mechanics performance experiment the production processing site,and the system has a great application value. |
