摘　　要：数据采集技术是实现制造执行系统(MES)的关键,而目前MES在电子电路表面贴装(SMT)生产中的应用还很少,因此对数据采集技术的研究变得越来越重要。针对以上问题,对SMT中MES的数据采集技术进行了研究,并通过RS232串行接口的通讯原理,给出基于RS 232接口标准的SMT数据采集技术的详细流程。使用VC++为开发平台,以贴片机为例进行数据采集实验,实验结果表明,该数据采集技术能实时采集设备的数据,方便、灵活、便于扩充。Data acquisition technology is the key of Manufacturing Execution System（MES）, however,the present MES in the electronic circuit Surface Mount（SMT） producting is still limited, so the study on data acquisition techniques becomes more and more important. To solve these problems, the data acquisition techniques of MES in SMT need to be studied. And a detailed data acquisition process in SMT is given based on RS 232 interface standard, through introducing the communication principle of RS 232 serial interface. Using VC^＋ ＋ as a development platform, taking Mounter for example to dp experiment. The results show that the data acquisition technology studied in this paper can gather the data of equipments in real -time,and it is convenient, flexible, easy to expand.
