G20数(shu)(shu)据(ju)采集(ji)仪，简称数(shu)(shu)采仪，应用于在线监(jian)测系统的现场(chang)端(duan)。数(shu)(shu)采仪是(shi)实现采集(ji)、存储、处理各种监(jian)测仪器仪表及传(chuan)感器的数(shu)(shu)据(ju)，并(bing)完成与(yu)应用平台数(shu)(shu)据(ju)传(chuan)输的数(shu)(shu)据(ju)终端(duan)单元(yuan)，具备(bei)单独的数(shu)(shu)据(ju)处理功能。

    数(shu)(shu)采仪是现场(chang)与应(ying)用(yong)平(ping)台(tai)连接的重要(yao)仪器。数(shu)(shu)采仪通(tong)(tong)过(guo)(guo)数(shu)(shu)字通(tong)(tong)道、模拟通(tong)(tong)道、开关(guan)量通(tong)(tong)道采集监测(ce)(ce)仪表(biao)及传感器的监测(ce)(ce)数(shu)(shu)据(ju)(ju)、状态等信息(xi)，然后通(tong)(tong)过(guo)(guo)传输(shu)网(wang)络将数(shu)(shu)据(ju)(ju)、状态传输(shu)至(zhi)应(ying)用(yong)平(ping)台(tai)；应(ying)用(yong)平(ping)台(tai)通(tong)(tong)过(guo)(guo)传输(shu)网(wang)络发送控(kong)制命令，数(shu)(shu)采仪根(gen)据(ju)(ju)命令控(kong)制监测(ce)(ce)仪表(biao)工作。
