基于单总线通信技术A/D芯片的数据采集卡

Data acquisition card based on the 1-wire bus communicate technology A/D chip

针对应用数据采集的场合越来越多的情况,设计了基于单总线通信技术A/D芯片的数据采集卡,用单总线A/D转换芯片DS2450遵从单总线通信协议,将其转换结果采集到单片机的存储器中,PC机通过ISA总线利用VC++6.0编程实现,读取并显示转换结果。该采集卡可以应用在多种场合,为现场采集数据提供便利。

The acquisition of the local data is very important to the production and research. In this ease, the data acquisition card based on the 1-wire bus communicate technology A/D chip is designed. The A/D chip DS2450 follows the 1-wire bus communication protocol, and inputs the results to the register of 8751 chip. PC utilizes ISA bus, and is programmed with VC ＋ ＋ 6.0. The results can be read and displayed. This card can be used in many occasions and it can offer convenience to the local data collection.
