数据采集系统的设计

单片机作为微型计算机的一个分支，其应用系统的设计方法与一般的微型计算机应用系统的设计在许多方面是一致的。但由于单片机系统通常作为系统的最前端，设计时更应注意应用现场的工程实际问题，使系统的可靠性能够满足应用的要求。数据采集是单片机应用系统中最为重要和普遍的应用要求。数据采集的对象可以是温度、压力、流量等各种物理量。数据采集系统可以是复杂控制系统的一部分，也可以是配备显示（或打印）输出的独立系统（或仪表）。

Design of the Data Collecting System

The one-chip computer is regarded as a branch of the microcomputer,the designs of the design method of its application system and general miniature computer application system are unanimous in many aspects. But because of one-chip computer usually as to foremost, should notice using the project practical problem of the scene even more when the design system system, make the reliahle performance of the system enough to meet the request of using. It is an one-chip computer that the data are gathered the most important and general application is required in application systems. The target that the data are gathered can be such various kinds of physical quantities as temperature, pressure, flow, etc.. The data collecting system can be a part of the complicated control system, can allocate and show （or type） that exports the independence systematically （or the instrument） too.
