基于F2806平台碳硫分析仪数据采集板设计

Design of data acquisition board for Carbon–Sulfur Analyzer

摘要:

针对传统碳硫分析仪单片机控制频繁出现通信中断及接口单一的情况，以TMS320F2806数字信号处理器作为主控单元，设计了24位高精度ADS1224芯片模数转换电路、CH376 USB通讯电路以及W5500以太网通讯电路。在CCS2.0环境实现了TMS320F2806处理器对各功能模块的SPI程序控制。调用CH376 API函数、Socket套接字编程在VC++6.0平台分别测试了USB与以太网双接口数据传输性能。结果表明TMS320F2806与各功能模块电路设计准确、时序控制有效。数据分析的准确性与精密性可以满足在工业环境下铁基合金中碳量与硫量的测定。

Abstract:

A data acquisition board used in Carbon sulfur analyzer was proposed based on TMS320F2806 Controller . 24-bit high precision chip ADS1224 sampled the output of infrared detector . At the same time, with the help of CH376 USB module and W5500 Ethernet module ,the data from the ADS1224 was transmitted from data acquisition board to pc . Double interface of carbon- sulfur analyzer was tested based on VC++6.0 platform. Comparing to conventional Carbon sulfur analyzer, the results show that the system works stably .accurately and effectively.
