数据采集系统硬件设计与实现

Data Acquisition System Hardware Design and Implementation

本方案利用SPCE061A集成的ADC直接将采集到的模拟信号转化为数字信号,为了保证转换的精度,在数据处理方面采用16次平滑滤波;在控制方面采用数字PID控制方案,控制效果十分理想;在进行数据处理的同时将当前的温度结果直接通过USB接口传送至上位PC,可以直接在PC端观察温度的变化曲线,并根据需要进行相应的数据分析和处理。本设计方案综合应用了系统SPCE061A的AD、Timer、TimeBase、UART等众多资源,发挥了SPCE061A的优异性能。主要说明了数据采集系统硬件设计与实现。

The program uses SPCE061A integrated ADC will be collected directly to the analog signal into a digital signal conversion in order to ensure the accuracy of the data processing smoothing filter used 16 times; in control, digital PID control scheme to control the results are quite satisfactory; in data processing, while the temperature of the results of the current directly through the USB interface to send first-bit PC, can be observed directly in the PC - side temperature curve, and in accordance with the need for appropriate data analysis and processing. The design of the system SPCE061A comprehensive application of the AD, Timer, TimeBase, UART, and many other resources, has played a SPCE061A＇ s excellent performance.
