摘　　要：介绍基于STC12C5A60S2单片机高速A/D转换方法。该方法充分利用STC12C5A60S2内部的硬件资源,实现了低成本、高性能的A/D转换。数据采集器将现场的模拟量经放大送STC12C5A60S2进行A/D转换后变成数字量传输到主机进行处理。本系统除了能获得较快的A/D转换速度外,转换的分辨率也可灵活设置,具有一定的使用价值。The method of based on high-speed transformation of A/D of STC12C5A60S2 SCM is introduced. The method takes full advantage of hard ware resources within the STC12C5A60S2 and it achieves low-cost, high-performance transformation of A/D. Data collector enlarges the analog in scene to send in STC12C5A60S2 conducted by A/D to convert them into digital data to transmit to the host for processing. In addition, this system can get a faster speed of transformation of A/D , the resolution of transformation can also set flexibly and it has a certain value.
