本文主要解决了计算机模拟采集领域中的两个问题：一是一块Ａ／Ｄ转换芯片可带动２ｎ（ｎ＝０，１，２，…）路模拟量的模／数转换；二是２ｎ路模拟量的转换既可以是均等的，也可以是加权的，而且转换结果的获取对控制机来说是绝对可靠的，且是实时的，本文就其工程实践提出了一系列的解决措施。
This paper mainly solves two problems in the field of computer simulation acquisition: one is that an A / D conversion chip can drive analog / digital conversion of 2n (n = 0, 1, 2, ...) The amount of conversion can be either equal or weighted, and the conversion result is absolutely reliable for the control machine, and it is real-time. In this paper, a series of solutions are put forward for its engineering practice.
